Problems solved by technology

[0002] The construction plant is built directly on the ground, which causes the ground to bear a lot of pressure, but the ground's bearing capacity for pressure is often relatively poor. In order to ensure the stability of the construction plant, it is often necessary to reinforce the ground or improve the ground. In the face of pressure bearing, the most common way is to drive piles on the foundation, but the existing pile driving method is only to drive the prefabricated pile foundation directly into the foundation, the pile foundation has the same diameter up and down, and the bottom of the pile foundation faces the bottom The area for pressure transmission is small, which leads to the low bearing capacity of the pile foundation, which leads to poor stability of the building built on the pile foundation, and has certain safety hazards

Embodiment 1

[0038] Embodiment 1: A kind of construction plant pile foundation, refer to the attached figure 1 , including a cylindrical pile basic body 1, a pile tip 2 fixedly connected to the bottom of the pile basic body 1, and a connecting pipe 4 fixedly connected to the middle position of the top of the pile basic body 1; the pile tip 2 is conically arranged and connected to the pile The base body 1 is coaxial, and the sharp corner of the pile tip 2 is located on the side of the pile tip 2 away from the pile base body 1; the connecting pipe 4 is arranged coaxially with the pile base body 1 .

[0039] See attached figure 2 And attached image 3, the top of the pile basic body 1 is provided with a groove 11, the connecting pipe 4 is located in the groove 11, the height of the top of the connecting pipe 4 is lower than the height of the top of the groove 11; the groove 11 is circularly arranged and the groove 11 is connected to the The tube 4 is coaxially arranged; the bottom of the c...

Embodiment 2

[0043] Embodiment two: a kind of construction workshop piling process, comprises the following steps:

[0044] a. Determine the pile position: measure and mark the position on the ground where piles need to be driven;

[0045] b. Ground cleaning: Before piling, the ground needs to be cleaned up, and the construction site needs to be investigated, and overhead wires, underground wires, water supply and drainage pipes and other facilities that hinder the construction and affect the safe operation of the construction should be removed first. and displacement, and then carry out subsequent construction;

[0046] c. Pile driver in place: move the pile driver to the position where piling needs to be performed, and make the pile driver vertical, fix the fixed equipment such as locks for hoisting, and lift the basic body 1 of the pile so that the position of the pile tip 2 is aligned with the center of the pile position, Then slowly put the pile basic body 1 into the soil, and the...

Embodiment 3

[0050] Embodiment three: a kind of construction workshop piling process, comprises the following steps:

[0051] a. Determine the pile position: measure and mark the position on the ground where piles need to be driven;

[0052] b. Ground cleaning: Before piling, the ground needs to be cleaned up, and the construction site needs to be investigated, and overhead wires, underground wires, water supply and drainage pipes and other facilities that hinder the construction and affect the safe operation of the construction should be removed first. and displacement, and then carry out subsequent construction;

Abstract

The invention discloses a construction workshop pile foundation and a construction workshop piling process using the pile foundation, relates to the technical field of pile foundation construction, solves the problem of low bearing capacity of the existing pile foundation, and the main point of the technical scheme is that the pile foundation includes pile Basic body, pile tip and connecting pipe; the bottom of the connecting pipe is provided with a connecting hole; Determine the pile position; b. Ground cleaning; c. The pile driver is in place; d. Pile stabilization and piling; e. High-pressure gas loosens the soil; f. Cement slurry pouring; high-pressure gas is sprayed through the jet holes around the bottom of the pile foundation to loosen the soil near the bottom of the pile foundation, and the slurry is sent into the gaps in the soil near the bottom of the pile foundation through the jet holes, so that the cement After the grout is solidified, the contact area between the bottom of the pile foundation and the bottom of the foundation will be increased, and the bearing capacity of the pile foundation will be improved.

Description
