Abstract
The invention discloses a kind of drilled pile pile foundation secondary pile hole cleaning device, comprise clear water pressurizer, described clear water pressurizer comprises the body of a top closure, and on the roof of body, have two holes, and each described hole is provided with being in charge of of upwards extending, and one of them is in charge of and is connected with High Pressure Air Compressor, another is in charge of and is connected with clear water supply line, the bottom of described body and the tubes connection of pile foundation.Simultaneously the present invention also provides a kind of method utilizing this device to carry out hole clearly, by injected clear water and compressed air in clear water pressurizer conductive pipe, clear water is arrived at the bottom of stake holes hole fast, and is mixed to form mud with sediment and flows out stake holes, enters sedimentation basin.The present invention can ensure the quality of pile, and simple to operate, speed is fast, efficiency is high.
Description
Technical field
The present invention relates to bored pile mud replacement technique, be specifically related to a kind of drilled pile pile foundation secondary pile hole cleaning device and clear hole method.
Background technology
After drilled pile pile foundation puts in place under reinforcing cage, if not poured pile base concrete immediately, dregs in stake holes in mud can precipitate again, cause pile bottom sediment blocked up, when pile bottom sediment reaches the bearing capacity that certain thickness can reduce stake, in order to ensure carrying out smoothly of filling concrete, secondary pile hole cleaning must be carried out, clear hole is the mud substituted in foramen primum, cascalho in cleaning hole, and before reducing perfusion, the relative density, sand factor etc. of slurries make its index that conforms with the regulations.Adopt tradition conventional change slurry processes carry out clearly hole time, because clear water proportion is little compared with mud, the mixing velocity of clear water and mud is slow, causes clearly that hole efficiency is low, consuming time longer.
Summary of the invention
The object of the present invention is to provide a kind of efficiency high, can ensure that clear hole quality meets the drilled pile pile foundation secondary pile hole cleaning device of actual needs and utilizes this device to carry out the method in hole clearly.
For reaching above-mentioned purpose, drilled pile pile foundation secondary pile hole cleaning device provided by the invention, comprise clear water pressurizer, described clear water pressurizer comprises the body of a top closure, and on the roof of body, have two holes, and each described hole is provided with being in charge of of upwards extending, and one of them is in charge of and is connected with High Pressure Air Compressor, another is in charge of and is connected with clear water supply line, the bottom of described body and the tubes connection of pile foundation.
The lower end of described conduit is 5 ~ 15cm apart from the distance at the bottom of stake holes hole.
The diameter of described body and the internal diameter of conduit suitable.
Another technical problem to be solved by this invention, provide a kind of and utilize above-mentioned drilled pile pile foundation secondary pile hole cleaning device to carry out the method in hole clearly, its step is as follows:
Step one, conduit 2 is dropped to 5 ~ 15cm at the bottom of stake holes 1 hole;
Step 2, clear water pressurizer is arranged on the upper end of conduit;
Step 3, on clear water pressurizer is in charge of is connected with High Pressure Air Compressor, another on clear water pressurizer is in charge of and is connected with clear water supply line;
Step 4, open the valve of clear water supply line, and start High Pressure Air Compressor, by injected clear water and compressed air in clear water pressurizer conductive pipe, clear water is arrived at the bottom of stake holes hole fast, and be mixed to form mud with sediment and flow out stake holes, enter sedimentation basin;
Step 5, after the concentration of hydraulic mixture in stake holes reaches set quota, close valve and the High Pressure Air Compressor of clear water supply line.
The invention has the beneficial effects as follows: because the present invention utilizes injected clear water and compressed air in clear water pressurizer conductive pipe, the clear water liquid level pressure in conduit is made to be greater than slurry liquid surface pressure outside conduit, at the bottom of clear water in conduit will arrive at fast, the disturbance velocity of pile bottom sediment is accelerated, clear water and sediment rapid mixing also form mud, along with the continuous injection of clear water, mud just can dilute gradually and discharge stake holes, until the concentration of mud reaches required standard.So the present invention can ensure the quality of pile, and simple to operate, speed is fast, efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of clear water pressurizer in the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Drilled pile pile foundation secondary pile hole cleaning device as depicted in figs. 1 and 2, comprise clear water pressurizer 3, described clear water pressurizer 3 comprises the body 3a of a top closure, and on the roof of body 3a, have two holes, and each described hole is provided with upwards extend be in charge of 3b, and one of them is in charge of 3b and is connected with High Pressure Air Compressor 4, another is in charge of 3b and is connected with clear water supply line 5, and the bottom of described body 3a is connected with the conduit 2 of pile foundation.The lower end of described conduit 2 is 5 ~ 15cm, preferably 10cm apart from the distance at the bottom of stake holes 1 hole.
As shown in Figure 1, utilize above-mentioned drilled pile pile foundation secondary pile hole cleaning device to carry out the method in hole clearly, its step is as follows:
Step one, conduit 2 is dropped to 5 ~ 15cm, preferably 10cm at the bottom of stake holes 1 hole;
Step 2, clear water pressurizer 3 is arranged on the upper end of conduit 2;
Step 3, on clear water pressurizer 3 is in charge of 3b is connected with High Pressure Air Compressor 4, another on clear water pressurizer 3 is in charge of 3b and is connected with clear water supply line 5;
Step 4, open the valve of clear water supply line 5, and start High Pressure Air Compressor 4, by injected clear water and compressed air in clear water pressurizer 3 conductive pipe 2, enable clear water arrive at the bottom of stake holes 1 hole fast, and be mixed to form mud with sediment and flow out stake holes 1, enter sedimentation basin;
Step 5, after the concentration of hydraulic mixture in stake holes 1 reaches set quota, close valve and the High Pressure Air Compressor 4 of clear water supply line 5.
The present invention utilizes injected clear water and compressed air in clear water pressurizer 3 conductive pipe 2, the clear water liquid level pressure in conduit 2 is made to be greater than slurry liquid surface pressure outside conduit 2, at the bottom of clear water in conduit 2 will arrive at fast, the disturbance velocity of pile bottom sediment is accelerated, clear water and sediment rapid mixing also form mud, along with the continuous injection of clear water, mud just can dilute gradually and discharge stake holes 1, until the concentration of mud reaches required standard.
