Abstract
The invention discloses a drilling pile foundation secondary hole cleaning device which comprises a clean water pressurizer, wherein the clean water pressurizer comprises a pipe body with a sealed top end, two holes are formed on the top wall of the pipe body, upward extending branch pipes are respectively arranged on the holes, one branch pipe is connected with a high pressure air compressor, the other branch pipe is connected with a clean water supply pipe, and the bottom end of the pipe body is connected with a guide pipe of a pile foundation. The invention further provides a hole cleaning method by using the drilling pile foundation secondary hole cleaning device. The hole cleaning method is characterized in that the clean water pressurizer injects clean water and compressed air into the guide pipe, and the clean water can fast reach the hole bottoms of the pile holes and is mixed with sediments to form mud to flow out of the pile holes and flow into a settling pond. The drilling pile foundation secondary hole cleaning device and method can ensure the quality of finished piles and is simple to operate, fast and high in efficiency.
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 hole cleaning device and clear hole method.
Background technology
After the drilled pile pile foundation puts in place under reinforcing cage, if poured pile base concrete immediately not, dregs in the stake hole in the 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 guarantee carrying out smoothly of concrete perfusion, must carry out the clear hole of secondary, clear hole is the mud of substituting in the foramen primum, cascalho in the cleaning hole, and the relative density of slurries, sand factor etc. make its index up to specification before reducing to pour into.When adopting the conventional slurry method of changing of tradition to carry out clearly the hole, because clear water proportion is little than mud, the mixing velocity of clear water and mud is slow, causes that hole efficient is low clearly, and is consuming time longer.
Summary of the invention
The object of the present invention is to provide a kind of efficient height, can guarantee that clear hole quality satisfies the drilled pile pile foundation secondary 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 hole cleaning device provided by the invention, comprise the clear water pressurizer, described clear water pressurizer comprises the body of a top closure, and have two holes at the roof of body, and be provided with upwardly extending being in charge of on each described hole, and one of them is in charge of with High Pressure Air Compressor and links to each other, another is in charge of with the clear water supply line and is connected, and the bottom of described body is connected with the conduit of pile foundation.
Distance at the bottom of the hole, following end distance stake hole of described conduit is 5～15cm.
The diameter of described body and the internal diameter of conduit are suitable.
Another technical problem to be solved by this invention provides a kind of and utilizes above-mentioned drilled pile pile foundation secondary hole cleaning device to carry out the method in hole clearly, and its step is as follows:
Step 4, open the valve of clear water supply line, and start High Pressure Air Compressor, by injecting clear water and compressed air in the clear water pressurizer conductive pipe, clear water can be arrived at the bottom of the hole, hole fast, and mixes with sediment and to form mud and flow out a hole, enter sedimentation basin;
The invention has the beneficial effects as follows: inject clear water and compressed air in the clear water pressurizer conductive pipe because the present invention utilizes, make the interior clear water liquid level pressure of conduit greater than the outer mud liquid level pressure of conduit, at the bottom of clear water in the 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 and discharge a stake hole gradually, reaches required standard up to the concentration of mud.So the present invention can guarantee the quality of pile, and simple to operate, speed is fast, efficient is high.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of clear water pressurizer among the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Drilled pile pile foundation secondary 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 have two holes at the roof of body 3a, and be provided with the upwardly extending 3b of being in charge of on each described hole, and one of them is in charge of 3b and links to each other with High Pressure Air Compressor 4, and 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 of pile foundation 2.Distance at the bottom of 1 hole, following end distance stake hole of described conduit 2 is 5～15cm, preferably 10cm.
As shown in Figure 1, utilize above-mentioned drilled pile pile foundation secondary hole cleaning device to carry out the method in hole clearly, its step is as follows:
Step 4, open the valve of clear water supply line 5, and start High Pressure Air Compressor 4, by injecting clear water and compressed air in clear water pressurizer 3 conductive pipe 2, clear water can be arrived at the bottom of 1 hole, a hole fast, and mix with sediment and to form mud and flow out a stake hole 1, enter sedimentation basin;
The present invention utilizes in clear water pressurizer 3 conductive pipe 2 and injects clear water and compressed air, make clear water liquid level pressure in the conduit 2 greater than the outer mud liquid level pressure of conduit 2, at the bottom of clear water in the 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 and discharge a stake hole 1 gradually, reaches required standard up to the concentration of mud.
