Embodiment 1

[0040] Specifically, the ventilation pipe 3 is built in parallel in the pipe wall of the ventilation sink 1, and the high-pressure airflow of the air compressor is introduced into the bottom inner wall of the ventilation sink 1 through the air pipe 3, and is released at the air outlet 6 of the inner wall. When the rapid pile forming device works, the power device 2 is activated, the power device 2 drives the ventilation sinker 1 to rotate, and a number of conical pins 8 are arranged on the lower surface of the ventilation sinker 1. When the ventilation sinker 1 descends, it encounters relatively hard When there are stones or hard soil, the conical pin 8 rotates with the ventilation immersion tube 1, which can break or loosen the harder stones or hard soil, so that the ventilation immersion tube 1 can sink into the soil more easily. When the ventilation immersion pipe 1 is sunk into the ground to a certain depth, the air compressor 5 is started, and the compressed air is filled ...

Embodiment 3

[0044] see Figure 4-Figure 6As shown, the ventilation pipe 3 can be solved by fixing the small-diameter steel pipe on the inner wall, the outer wall and the middle of the ventilation sink pipe 1 in parallel. If the ventilation tube 3 is arranged in the middle of the ventilation sink tube 1 , connecting blocks are arranged at intervals in the longitudinal direction to fix the ventilation tube 3 and the inner wall of the ventilation sink tube 1 . When the rapid piling device works, the power device 2 is activated, the power device 2 drives the ventilation sinker 1 to rotate, and a number of conical pins 8 are arranged on the lower surface of the ventilation sinker 1. When the ventilation sinker 1 descends, it encounters relatively hard When the rock or hard soil is hard, the conical pin 8 rotates with the ventilation immersion tube 1, which can break or loosen the harder stone or hard soil, so that the ventilation immersion tube 1 can sink into the soil more easily. When the v...

Abstract

The invention belongs to the field of engineering construction, and particularly relates to a rapid pile forming device and a pile forming method thereof. The rapid pile forming device comprises a ventilation immersed tube, wherein at least one ventilation tube is arranged on the wall of the ventilation immersed tube; one end of the ventilation tube is connected with an air compressor; the other end of the ventilation tube is provided with an air outlet; the air outlet is located in the inner wall of the ventilation immersed tube; and the outer wall of the ventilation immersed tube is connected with a power device. According to the rapid pile forming device, soil in the ventilation immersed tube is discharged to form a hole through compressed air mainly and air pressure. By means of the rapid pile forming way, the working efficiency is improved, and the pile foundation construction cost is reduced. The discharged soil, curing agents such as cement and materials such as water are mixedto form a flow-state mixture to be poured into a pile, so that the stirring uniformity of the curing agents such as cement and the soil and the construction efficiency of the whole construction process are improved. Meanwhile, the whole construction cost is greatly reduced, the whole structure is simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the field of engineering construction, and in particular relates to a rapid pile forming device and a pile forming method. Background technique [0002] At present, in the field of engineering construction, especially in the field of foundation pit support, SMW construction method piles are widely used. SMW construction method piles are particularly affected by factors such as stratum conditions, equipment status and the proficiency of construction operators. Many projects have many problems, which affect the construction period and construction cost of the project. The principle of SMW construction method is to use special equipment to mix cement and other solidifying agents and soil evenly to form a cylindrical shape with a certain depth, insert a section steel in the center of the cylindrical shape, and combine the cement and soil with the section steel to form a combination with a certain bending resistance. This kind of c...
