Abstract
Description
Technical Field
[0001] The invention relates to a method for treating water leakage between piles of full-tube bite piles in a subway station, belonging to the technical field of subway construction. The invention also relates to a drainage device for water leakage between piles of full-tube bite piles in a subway station. Background Art
[0002] In the construction of urban rail transit projects, most subway stations are located in busy areas of the city. Construction in busy areas is inevitably restricted by the site and road traffic. In order to reduce the impact of construction on the surrounding environment, the construction of subway stations with full-tube bite piles has become more common and the technology has become more mature. Full-tube bite piles are a kind of foundation pit retaining structure, which is composed of an unreinforced super-slow-setting concrete pile (A pile) and a reinforced concrete pile (B pile) arranged at intervals. By forming a mutual bite arrangement between the piles, a good anti-seepage and retaining effect is achieved. During the construction process, the construction sequence and timing of piles A and B are crucial to prevent leakage between piles. When leakage occurs between piles, the conventional method is to find the leakage point and then plug it. Because the leakage point between piles is hidden and difficult to be found, the conventional plugging method is easy to be incomplete, and often there is a situation where one side is plugged and the other side leaks, which makes it difficult to plug the leakage and wastes a lot of manpower and material resources. In addition, the conventional plugging method cannot achieve rapid plugging operations, which affects subsequent construction. Summary of the invention
[0003] In view of the above-mentioned defects existing in the prior art, the present invention provides a method for treating the leakage water between two whole piles without finding the leakage point or plugging the leakage point.
[0004] The present invention is realized through the following technical scheme: a method for treating water leakage between piles of full-pipe bite piles in a subway station, characterized in that: after a leaking pile is found, a drainage pipe made of PVC material is vertically arranged in the inner pile seam of the leaking pile, a plurality of drainage holes are arranged on the pipe body of the drainage pipe, and then a horizontally arranged drainage groove is respectively arranged in the middle and bottom of the pile seam with a quick leak-stopping spirit and the drainage pipe is wrapped in the drainage groove, the drainage groove is sealed and connected to the pile bodies on both sides, the drainage groove is filled with crushed sponge to effectively collect the water leakage between the piles, and then a whole sponge block is covered on the outside of the drainage pipe along its height direction, and it is fixed to the pile body with a long nail; a collecting pipe is connected to the bottom of the drainage pipe; the water leakage between the piles enters the drainage pipe through the drainage holes on the drainage pipe and is drained out through the collecting pipe.
[0005] In the present invention, two drainage grooves divide the pile joint into two parts, the middle drainage groove is used to collect the leakage water in the upper part of the piles, and the bottom drainage groove is used to collect the leakage water in the middle and lower parts of the piles. The leakage water between the piles and the leakage water collected in the drainage groove can enter the drainage pipe through the drainage holes on the drainage pipe, and be discharged through the collection pipe connected to the drainage pipe at the bottom. The whole sponge block arranged outside the drainage pipe can absorb the leakage water itself on the one hand, which is convenient for collecting the leakage water between the piles. On the other hand, it can prevent the external concrete from clogging the drainage hole, thereby ensuring the drainage effect. The method of the present invention can effectively collect the leakage water between the piles without affecting the subsequent construction.
[0006] Furthermore, the distance between the drainage trough at the bottom and the bottom of the pile is 1 m.
[0007] Furthermore, to ensure the drainage effect, the diameter of the drainage hole of the drainage tube is 10 mm.
[0008] The present invention also provides a leakage drainage device between piles of a full-sleeve interlocking pile in a subway station, which is characterized in that it includes a drainage pipe, a drainage groove, and a collecting pipe. The drainage pipe is vertically arranged in the pile gap on the inner side of the leaking piles and is arranged to pass through the pile gap up and down. A plurality of drainage holes are arranged on the pipe body of the drainage pipe. The collecting pipe is connected to the lower end of the drainage pipe. A horizontally arranged drainage groove is respectively arranged in the middle and bottom of the pile gap. The drainage groove is sealed and connected to the pile body surfaces on both sides, and the drainage groove at least extends to a position tangent to the outer diameters of the two pile bodies. A plurality of broken sponge blocks are arranged in the drainage groove. The drainage pipe passes through the drainage groove and a sealing arrangement is arranged between the two. The outer side of the drainage pipe is covered with a whole sponge block along its height direction.
[0009] Furthermore, the diameter of the drainage hole of the drainage tube is 10 mm.
[0010] Furthermore, the distance between the drainage trough at the bottom and the bottom of the pile is 1 m.
[0011] The beneficial effects of the present invention are as follows: the present invention can effectively collect and drain the seepage water between the piles, and can drain the seepage water between two whole piles without directly finding the leakage point, without affecting the subsequent construction, greatly reducing the consumption of manpower and material resources, and can save a lot of construction costs. Moreover, the present invention has thorough drainage, and can effectively overcome the problems of difficult and incomplete plugging in conventional plugging methods. The present invention can conveniently and quickly use conventional materials to solve the problem of seepage water between piles under the premise of digging and draining, with fast construction speed, reduced construction period, and saved construction costs.

[0015] The present invention will be further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:
[0016] The following explanation is based on the use of full-casing interlocking piles in subway stations with a pile length of 18m and a pile diameter of 1m.
[0017] As shown in the attached drawings, a method for treating water leakage between piles of full-pipe interlocking piles in a subway station is provided. The method uses a drainage device to collect the water leakage between the piles and drain it out. The drainage device used is: including a drainage pipe 1, a drainage groove 3, and a collecting pipe 6. The drainage pipe 3 is a PVC pipe with a diameter of 25 mm. The drainage pipe 3 is vertically arranged in the pile gap on the inner side of the leaking pile and is arranged through the pile gap from top to bottom. The body of the drainage pipe 1 is provided with a plurality of drainage holes 5, and the diameter of the drainage hole 5 is 10 mm. The collecting pipe 6 is connected to the lower end of the drainage pipe 3. The drainage groove 3 is respectively arranged in the middle and bottom of the pile gap. The drainage groove 3 is arranged horizontally, and the drainage groove 3 is sealed and connected to the surface of the pile body 4 on both sides to collect the water leakage between the piles. To ensure the collection of the leakage water, the drainage groove 3 at least extends to a position tangent to the outer diameter of the two pile bodies. The drainage groove is an oval groove with a length of 40 cm and a height of 30 cm. The drainage groove 3 is filled with a number of broken sponge blocks to ensure the effective collection of water leakage between the piles. The drainage pipe 1 passes through the drainage groove 3 and the two are sealed. The outer side of the drainage pipe 1 is covered along its height direction with a whole sponge block 2 with a length of 17 m, a width of 0.4 m, and a thickness of 0.1 m.
[0018] The specific method of treating the leakage water between piles by using the above drainage device is:
[0019] After finding the leaking pile, the whole drainage pipe 1 is vertically set in the inner pile seam of the leaking pile, and then a drainage groove 3 is set in the middle and bottom of the pile seam respectively with quick leak-proof spirit and the drainage pipe 1 is wrapped in the drainage groove 3. The drainage groove 3 is sealed and connected with the pile bodies on both sides. The drainage groove at the bottom is 1m away from the bottom of the pile. The drainage groove 3 is filled with broken sponges to effectively collect the leaking water between the piles, and then a whole sponge block 2 with a length of 17m×width of 0.4m×thickness of 0.1m is covered on the drainage pipe 1 outside, and it is fixed on the pile body 4 with long nails every two meters. Finally, the collection pipe 6 is connected with a three-way joint at the bottom of the drainage pipe 1. In order to ensure the drainage effect of the three-way drainage pipe, the leak-proof spirit can be wrapped outside the three-way joint. The present invention can effectively collect the leakage water between piles through the larger drainage groove 3. The leakage water between piles enters the drainage pipe 1 through the drainage holes on the drainage pipe 1 and is drained out through the collection pipe 6. The leakage water between piles can be drained out at any time without affecting subsequent construction.
[0020] The quick leak-proof plugging agent used in the present invention is a waterproof leak-proof plugging material that can quickly solidify and harden. It is a prior art and can be purchased. The present invention uses the quick leak-proof plugging agent to quickly and reliably form the required drainage groove at the pile joint, and the construction is convenient and fast.
[0021] The method of the present invention is used to treat water leakage between piles of full-casing interlocking piles. There is no need to find the leakage points between the piles or to plug the leaks. The leakage water between the piles can be collected and drained out at any time through the drainage device, which does not affect the subsequent construction. The water leakage problem between the piles can be solved conveniently and quickly using conventional materials under the premise of digging and draining. The method effectively solves the problems of difficulty in plugging leaks, incomplete plugging, and large use of manpower and material resources in conventional plugging methods. The present invention adopts a drainage device to collect and drain the leakage water between the piles. The drainage is thorough, which can greatly reduce manpower and material resources and save a lot of construction costs.
[0022] The other parts of this embodiment are all prior art and will not be described in detail here.
