A pile stabilizing device for rock-socketed pile steel casing

Abstract

The invention discloses a pile stabilizing device for a socketed pile steel casing. The pile stabilizing device comprises the steel casing, a mold bag is arranged at the bottom end of the steel casing, and communicating pipes are arranged on the mold bag. End openings of the communicating pipes are formed over the water surface and provided with floating bodies so that it can be guaranteed that the communicating pipes are located over the water surface all the time, and concrete pouring guide pipes can be conveniently inserted in the communicating pipes at any time. The multiple communicating pipes are uniformly arranged on the mold bag so that it can be avoided that concrete pouring fails due to blockage of one communicating pipe, and concrete in the mold bag can be uniformly distributed. The pile stabilizing device has the advantages of being capable of ensuring the working performance of the steel casing, preventing the steel casing from leaking grout in the process of drilling a hole or pouring concrete in the hole, increasing the hole forming rate, shortening the construction cycle, improving the pile foundation hole construction efficiency and greatly reducing the pile foundation hole construction cost.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a steel casing stabilizing pile for rock-socketed piles and a leak-proof device, which is used for stabilizing piles with steel casings for bare rock foundations. Background technique [0002] Rock-socketed piles are currently widely used in pier and bridge pile foundation projects. For areas with thin or no covering layers, it is difficult to stabilize the steel casing of rock-socketed piles. Island stabilized pile method and independent drilling platform construction method. The pre-drilling method uses a drilling rig to pre-drill holes in the rock, and then inserts the steel casing into the hole, and then continues to make holes in the casing. This method requires high pre-drilling costs, low position accuracy, and the drilling process. Severe slurry leakage; the island building method requires a large amount of sand and gravel, which is difficult to use ...

Problems solved by technology

The pre-drilling method uses a drilling rig to pre-drill holes in the rock, and then inserts the steel casing into the hole, and then continues to make holes in the casing. This method requires high pre-drilling costs, low position accuracy, and the drilling process. Severe slurry leakage; the island building method requires a large amount of sand and gravel, which is difficult to use when the channel is narrow or the water flow rate is high, and the island building material is a non-adhesive material, and the filler is easy to leak into the hole during the drilling process In the construction method, not only the quality of the pile is affected, but also the casing will be unstable due to the leakage of the island building material; the independent drilling platform construction method uses the independent platform itself to stabilize the steel casing and drill holes, but the cost is high, and the mud in the casing cannot Guarantee, affect the quality of hole formation and concrete pouring quality
