Abstract

The invention belongs to the technical field of civil engineering construction, and relates to an immersed pipe device for the construction of cast-in-place piles in air-containing soil layers, which includes a hollow pipe body, and the upper and lower ends of the hollow pipe body are respectively detachably connected with an exhaust device and an air intake. device, the bottom of one end of the hollow pipe body is provided with an air intake device connected to the pile tip valve, and the air intake device is arranged between the pile tip valve and the block on the inner wall of the hollow pipe, and the air intake device consists of A breathable layer, a lightweight material layer and a filter layer connected in sequence from top to bottom, a plurality of air intake holes are distributed on the light material layer, a piston is arranged in the air intake hole, and a gap between the piston and the breathable layer Connected by springs. The invention is safe, reliable, cost controllable, and flexible to operate. On the one hand, it can prevent engineering disasters caused by gas eruption in the gas-bearing soil layer, and on the other hand, it can ensure the pile quality of the pile body. It is suitable for shallow seas and shallow gas distribution areas on land. And it can form the reuse of clean energy, and its engineering application prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to an immersed pipe device for construction of cast-in-place piles in air-containing soil layers and a construction method thereof. Background technique [0002] The most common gas-bearing soil layer is gas-bearing sediments distributed in marsh wetlands, estuaries, deltas, lakes and seabeds. Generally, various strata are distributed from 20m to 1500m below the surface, and this area will involve a lot of engineering construction. In order to prevent the impact of shallow gas geological disasters on construction projects, it is necessary to formulate a reasonable and reliable special construction plan. At present, pile foundation is the foundation form often used in air-bearing soil areas, and cast-in-situ piles have been proved to be extremely flexible by engineering practice, but traditional methods cannot be constructed in air-bearing soil are...
