Description

Technical Field

[0001] The utility model relates to the technical field of foundation piles, in particular to a building foundation pile construction device. Background Art

[0002] Pile foundation is a professional term in building structure. To understand its meaning, we must understand what pile foundation, group pile foundation and single pile foundation are. Pile foundation: a foundation composed of piles and a cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations.

[0003] Generally, when installing pile foundations, pressure is applied to the pile foundations by hammering them down so that the pile foundations are inserted vertically into the foundation. When the pile foundations are hammered down and inserted vertically into the foundation, the pile foundations may deviate from the vertical direction during the construction process. Such tilted pile foundations will cause differences in the density of the foundations around the pile foundations, which will seriously affect the stabilizing effect of the pile foundations on the foundations.

[0012] Furthermore, the multiple reset springs are all in a reset state, the multiple buffer springs are all in a compressed state, and the ends of the multiple push rods that are away from each other are chamfered. The chamfered setting of the push rods can make the arc-shaped push block and the push rod contact stably, avoiding motion interference between the push rod and the arc-shaped push block.

[0013] The beneficial effects of the utility model are:

[0014] 1.

The side surfaces of the multiple slides 2 that are away from each other are fixedly connected with buffer springs 9, and the other ends of the multiple buffer springs 9 are fixedly connected to the push rod 6 close to them. The installed buffer spring 9 can assist in buffering the impact force received by the slide 2 through the elastic deformation force of the spring, and can push the contact member 3 to reset through the reset force of the buffer spring 9.

[0024] The side surfaces of the multiple slides 2 that are close to each other are fixedly connected with return springs 10, and the other ends of the multiple return springs 10 are fixedly connected to the inner wall of the fixed frame 1. The installation of the return springs 10 can further buffer the impact force through the deformation force of the return springs 10, and cooperate with the slide 2 and the push rod 6 to squeeze the air in the slide 2 to achieve the energy absorption effect. The multiple return springs 10 are all in a reset state, and the multiple buffer springs 9 are all in a compressed state. The ends of the multiple push rods 6 that are away from each other are chamfered. The chamfered setting of the push rod 6 can make the arc-shaped top block 14 stably contact with the push rod 6, thereby avoiding motion interference between the push rod 6 and the arc-shaped top block 14.

[0025] The bottom surface of the fixed frame 1 is fixedly connected with a counterweight 11, and the bottom surface of the counterweight 11 is fixedly connected with a plurality of circumferentially distributed conical rods 12.
