Problems solved by technology

In order to avoid or reduce the above adverse effects, it is usually necessary to set up vertical drainage bodies in the foundation first, and take measures such as pile jumping construction technology. The construction technology of jumping piles is relatively complicated, which makes the construction operation complicated and the construction cost high

Embodiment Construction

[0007] Below in conjunction with accompanying drawing, the present invention is described in further detail;

[0008] like figure 1 As shown, a certain number of small holes 4 penetrating through the pipe wall 3 are opened on the pipe wall 3 of the pipe pile main body 1, a pipe pile driving part 2 is arranged on the upper part of the pipe pile main body 1, and a tapered pile is arranged on the lower part of the pipe pile main body 1. Boot 5, in the pile hole 8 of pipe pile main body 1, be placed with water pump 6, a drainage pipe 7 is installed on the water pump 6, and water pipe 7 other end passes pipe pile and replaces part 2, stretches to the outer end.

[0009] Before piling, first pass one end of the drainage pipe 7 through the pipe pile replacement part 2, put the water pump 6 at the other end of the drainage pipe 7 into the pile hole 8 of the pipe pile main body 1, and place the pipe pile replacement part 2 On the pipe pile main body 1, the piling can be started, and w...

Abstract

The invention provides a quick drainage tubular pile which comprises a tubular pile body and a tubular pile alternating beating piece. The quick drainage tubular pile is characterized in that small holes with a certain number are formed in the pipe wall of the tubular pile body, the small holes penetrate through the pipe wall, underground water can directly enter a pile hole, the tubular pile is prevented from bearing super-static hole water pressure, lateral displacement or ground protrusions are avoided, and therefore pile breakage, pile body inclination and other engineering accidents can be avoided, the tubular pile alternating beating piece is arranged on the upper portion of the tubular pile body, a conical pile shoe is arranged on the lower portion of the tubular pile body, a water suction pump is arranged in the pile hole of the tubular pile body, a drainage pipe is arranged on the water suction pump, and the other end of the drainage pipe penetrates through the tubular pile alternating beating piece and stretches to the outer end of the tubular pile alternating beating piece. The water in the pile hole can be directly pumped out through the water suction pump, and therefore the super-static hole water pressure in a foundation is promoted to dissipate, the soil-squeezing effect and post-construction settlement are reduced, the tubular pile can be normally used, and the quick drainage tubular pile is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a quick drainage pipe pile. Background technique [0002] Prefabricated pipe piles are widely used in construction projects because their quality is easy to guarantee and the bearing capacity of single piles is high. They are often used in foundation treatment construction. When pipe piles are constructed in viscous soil foundations, Excess static pore water pressure will be generated in the ground, causing lateral displacement or ground uplift, which may cause engineering accidents such as broken piles and pile body tilting, which will have a great impact on the construction quality of the project, and even cause irreparable losses. When the soil between the piles of the prefabricated tubular pile composite foundation bears a large load or the foundation soil is under-consolidated, there will be excess static pore water pressure between the piles. If there is no vert...
