. In Great Britain July 1, 1946 7 Claims.

The present invention relates to gulleys or catchpits for drainage purposes and particularly for road surface water drainage.

According to the present invention a gulley is formed of a number of gulley'sections superimposed one upon the other ofwhich at least one section, which is other than the lowermost or pit section, is provided with one or more openings or connections therein to permit of discharge from or inlet and discharge to and from the gulley. Preferably the lowermost section is closed at its lower end to form a closed ended gulley. V V

The invention includes an assembly of gulley sections adapted to be superimposed one upon the other to form a complete gulley, said sections including a bottom section which is preferably closed at one end and another section or sections having one or more openings or connections therein.

A further feature of the invention consists of an assembly of gulley sections adapted to be superimposed one upon the other to form a complete gulley in which three and preferably four openings are provided in one or more of said sections other than the lowermost or pit section and at least one pipe connection and at least one closure blank each adapted to be fitted in any one of said openings. 7

A still further feature of the invention consists of ,an assembly of gulley sections adapted to be superimposed. one upon the other to form a complete gulley and having one or more openings formed in the walls thereof complementarily in adjacent gulley sections. The centre ofeach opening should preferably coincide with the junction of the adjacent sections in which it is formed so that one half of each opening extends down wardly from the upper edge of one section and the other half extendsupwardly from the lower edge of the section next above.

The invention furthermore includes an assembly of gulley sections adapted to besuperimposed one upon the other to form acomplete gulleyand at least one blank and at leastone pipe connection each adapted to be receivedin any one of a number of openings formed inthe walls of said sections complementarily in adjacent sections other than the lowermost section, said connections and blanks being formed with an abutment or abutments thereon for locking engagement with the walls of the sections in which said openings are formed, whereby saidblanks and con nections can be locked in position in the openings formed between said adjacent section'sand at the same time serve to lock saidadjacent sec-' tions against transverse relative movement.

' The said pipe connections may be of different sizes or may include both spigot and socket connections.

The range of connections may include angled connections to enable pipes to be connected other than perpendicularly to the gulley. Thus for example a spigot or socket connection may be formed with the spigot or socket at an angle of 30 to the axis of that portion of the connection the said connections are preferably of circular or square cross-section to correspond with the shape of the gulley openings.

The sections are preferably keyed together by any suitable means. For example the inter-engaging end faces of the section may have opposed peripheral recesses or grooves or arcuate, V or other cross section adapted to receive a cement or other jointing material therebetween whereby to form a strip or bead engaging complementarily in the opposed recesses whereby to seal and'lock the sections against transverse Alternatively they may be keyed together by surround movement relatively to one another.

ing concrete or cement, and in one mode of carrying the invention into eifect the sections are relatively lightly constructed so as to require an' outer reinforcement of concrete, cement or the like in relation to which the sections act as a shuttering.

The manufacture of a gulley in a number of sections enables the sections to be handled more easily than a gulley formed in one piece and enables gulleys to be installed more quickly and cheaply than when made of brickwork. More-- over gulleys according to the present invention can be installed by unskilled labour whereas brickwork gulleys must be built by skilled labourf Since the gulley of the present invention is formed of sections the level of the openings or branches can be suitably arranged to suit local conditions and to suit the nature of the pipes with which the gulley is used. Thus a gulley used with metal pipes laid across a carriageway may have the openings or branches relatively high whilst if used with concrete pipes the openings or branches may be relatively low so as to afford protection for the pipes and to leave room when necessary for a suitable thickness of concrete to be placed around the pipes in the carriageway. Again gulleys of varying depth may be formed by the use of a greater or lesser number of sections or by the use of sections of greater or lesser depth and the depth of the pit beneath the openings or branches may be suitably chosen to correspond with the amount of silt which may be anticipated to collect in the gulley.

Gulleys according to the present invention can be used in a variety of ways to meet a variety of requirements. For example a gulley may merely collect water from a road and pass it away through an outlet opening or branch in which case it will require only one opening or branch in its side wall. In addition to collecting water from the road it may receive water from another gulley on the opposite side of the road or further up the road and pass the water away, in which case it will require two openings or branches, whilst again it may receive water from a gulley on the opposite side of the road and from another gulley spaced therefrom on the same side of the road and also discharge the water so collected in which case it will require three openings or branches. In certain cases it may be necessary for a gulley to have four openings or branches. In order to avoid or economise in the installation of inspection chambers it may often be advisable to connect a number of gulleys at one side of the road in series and these gulleys may be individually connected with individual gulleys on the opposite side of the road. In this arrangement inspection chambers may be entirely dispensed with or the gulleys may be connected at infrequent intervals with widely spaced inspection chambers.

These various requirements could be met by manufacturing a variety of branched or apertured gulleys but the present invention provides a range of standard gulley sections, pipe connections and blanks from which gulleys of suitable depth and having a suitable number of openings or branches can be built up to suit the various requirements.

For this purpose a preferred form of assembly consists of a closed ended pit section which may be of rectangular form, a pair of intermediate sections which are complementarily apertured to provide four openings spacedaround the periphery thereof with the centre of each aperture at the junction of the two sections, and other sections of varying depth which may be arranged above said apertured sections and/or if desired also intermediate of said apertured sections and the pit section. When the sections are of rectangular form said openings are preferably formed one in each face.

The formation of the openings in two adjacent gulley sections facilitates the installation of the closure blanks and the connections, since the blanksand connections can be set in the openigs in the lower section, whereupon the upper section may be applied.

The invention is further described with reference to the accompanying drawings in which:

Fig. 1 is a diagrammatic plan view illustrating by way of example a typical road drainage scheme which may be carried out with standard gulley assemblies according to the present invention.

Fig. 2 is a perspective view of a preferred form of concrete gulley according to the present invention.

Fig. 3 is a horizontal sectional view taken in the plane containing the axes of the connections.

Fig. 4 is a erspective view showing in spaced relationship the concrete gulley sections employed in the assembly of the gulley illustrated in Figs. 2 and 3.

Figs. 5 to 8 illustrate a number of pipe connections formed of concrete for use in conjunction with the gulley sections shown in Fig. 4.

Fig. 9 illustrates a blank formed of concrete for use in connection with the gulley sections shown in Fig. 4.

Fig. 10 is a sectional view of a pipe connection similar to that of Fig. 5 but with an angled spigot.

Fig. 11 is a sectional view of a trapped connection.

Fig. 1 illustrates a typical road drainage scheme which may be carried out with the standard gul-v ley assemblies of the present invention. Gulleys I, 2, 3; 4, 5 are arranged in series with one another on one side of a road so that the gulley I discharges into gulley 2 and the gulley 2 discharges into gulley 3 and so on whilst the end gulley 5 discharges through a connection 6 to a ditch, river, main drainage line or the like. Gulleys I, 8, 9, I3, I I on the opposite side of the road discharge respectively to the gulleys I, 2, 3, 4, 5. Thus the gulleys 1,3, 9, III, II require only a single outlet connection I2. The gulley I requires two connections I3 and I4. Gulley. 2 requires three connections I3, I4, I5. Gulley 3 requires three connections I3, I 5, l6. Gulley 4 requires. three connections I3, I6, I1, whilst gulley 5 requires three connections 6, I3, I1. The diameter of the pipes connecting the gulleys 3, 4 and 5 is greater than the dimeter of the pipes connecting the gulleys I, 2 and 3.

.The various gulleys required in the drainage scheme illustrated in Fig. 1 with different sizes, numbers and dispositions of connections can all be built up from standard gulley sections with standard blanks and connections in accordance with the present invention.

The gulley illustrated in Fig. 2 consists of gulley sections 20, 2|, 22, 23, 24 which are illustrated in spaced relationship in Fig. 4. It will be seen that the lowermost or pit section is closed at its lower end 25 to form a closed ended gulley. Two intermediate sections 2I, 22 have circular openings 26, 21, 28 and 29 formed complementarily in the side walls thereof with the centre of each opening at the junction of the sections 2I, 22. The said openings may if desired be of any other suitable shape such for example as square.

In they preferred form of construction illustrated the assembly consists of five gulley sec tions but an additional section or sections similar to the sections 23, 24 but of different depth may be included in order to increase the range of overall depth of the gulley which ma be built up and of course in the case of ashallow gulley, the sections 23 and 24 may be omitted.

Preferably each pair of opposing peripheral faces 30, 3| of the sections is provided with opposed peripheral grooves or recesses located approximately at the midwidth of the walls of the sections. For the sake. of clarity these grooves are not shown in the drawings. On assembly these grooves may be filled with cement or other jointing material to form a sealing and locking;

bead between each pair of interengaging sections. Each complete gulley includes a grid section 32 which may be of any suitable form and forms no part of the present invention.

It will be observed that the inner faces of the walls of the gulley sections 2|, 22 are each circularly recessed as at 33 to form a reduced wall portion or flange surrounding each opening 26, 21, 28, 29. The flange so formed is adapted to engage in an annular recess formed between flanges 34, I9 formed on standard connections 35, 36, 31, 38 illustrated in Figs. 5 to 8, and on standard blanks 39 illustrated in Fig. 9. Each recess 33 is adapted to receive the flange 34 of a standard connection or blank whereb to maintain a relatively smooth surface within the gulley. The dimensions of the flanges 34, I9 of the standard connections 35, 36, 31, 38 and blank 39 are all alike to enable any connection or blank to fit in any opening 26, 21, 28, 29 in sections 2|, 22.

Fig. 5 represents in front and side elevation a 6 inch standard spigot connection 35. Fig. 6 represents a 6 inch standard socket connection 36, Fig. 7 a 9 inch standard spigot connection 31 and Fig. 8 a 9 inch standard socket connection 38. The range of sizes of standard connections may of course be increased, and for example the range may include also 4 inch spigot and socket connections.

The range of connections may include angled spigot and socket connections and, by way of example, an angled spigot connection 40 is shown in Fig. 10 wherein the spigot 4| is inclined at an angle of about to the axis of the flanges I9, 34.

The range of connections may also include one or more trapped connections to enable a gulley to be connected to a foul sewer. Such a trapped connection 42 is shown by way of example in Fig. 11. This connection embodies the flanges I9, 34 and a well 43 depending from its lower side. An isolating wall 44 extends downwardly from the upper side of the connection and enters the wall 43. The isolating wall 44 preferably has a rodding aperture 45 therein approximately coincident with the axis of the connection to enable a rod to be passed therethrough to clear an obstruction, the aperture 45 being normally sealed by a suitable plug.

It will be appreciated that the gulleys 1, 8, 9, I0, H as shown in Fig. 1 can each be built up using gulley sections 2024 as shown in Fig. 4 with three standard blanks 39 closing three of the openings 26, 21, 28, 29 and using a standard spigot or socket connection 35 or 36 to form the outlet 12. If a large number of gulleys 1H were required a number of gulley sections 2|, 22 having only a single opening 26 or 21 could be constructed. The gulley I can be formed by using two blanks 39 and two of the connections 35, 36. The gulley 2 can be formed by using one blank 39 and three of the connections 35, 36. The gulley 3can be formed by using one blank 39, two of the connections 35, 36 and one of the connections 31, 38. Gulleys 4 and 5 can be formed by using one blank 39, one of the connections 35, 36 and two of the connections 31, 38.

It will be observed that the gulley illustrated in Figs. 2 and 3 corresponds to the gulley 4 shown in Fig. 1 and is built up with opposed 9 inch spigot and socket connections 31, 38 with a blank 39 and a 6 inch spigot connection 35.
