Combined pile and construction technology thereof

Abstract

The combined pile comprises a fixing pile column, a fixing hole is formed in the inner wall of the middle of the fixing pile column, a protection hollow end is fixedly connected to the inner wall of the fixing pile column, a hydraulic extrusion column is connected to the inner wall of the protection hollow end in a sleeving mode, and a threaded groove is formed in the outer wall of one end of the hydraulic extrusion column; the outer wall of one end of the fixed pile is movably sleeved with a fixed friction end, and a threaded groove is formed in the inner wall of the fixed friction end. According to the device, the fixing pile is arranged, so that the device fixing effect is achieved, force transmission is facilitated through the hydraulic extrusion column, control over the whole device by hoisting equipment is facilitated through the fixed friction end, the buffering effect is achieved through the telescopic fixing hollow cabin and the elastic spring, and the fixing circular ring is arranged, so that the device is convenient to use. And through the arrangement of the first hydraulic cabin, the hydraulic transmission column and the second hydraulic cabin, transmission of hydraulic oil is facilitated.

Description

technical field [0001] The invention relates to the technical field of pile body installation, in particular to a combined pile and a construction technique thereof. Background technique [0002] Piling refers to driving the piles into the ground to make the foundation of the building firm; while the end-bearing pile is a pile whose superstructure load is mainly borne by the resistance of the pile end. In the stress layer, the final penetration is mainly controlled during piling, and the soil entry elevation is used as a reference. The final penetration should be measured when there is no damage to the top of the pile, no eccentricity when hammered, the drop distance of the hammer meets the regulations, and the pile cap and pile pad are normal, etc. proceed below. [0003] In the process of using traditional piles, the piles are generally put into the reserved pits manually, and then the concrete is poured manually to achieve the purpose of fixing. In the process of not po...

Problems solved by technology

[0003] In the process of using the traditional piles, the piles are generally put into the reserved pit body manually, and then the concrete is artificially poured to achieve the purpose of fixing, but the traditional piles are in In the process of not pouring, it mainly relies on its own weight to achieve a stable effect. During the process of stabilization, the body shape may tilt, and then it needs to be stabilized by manual use of lifting equipment, which is very important. It is troublesome, and the piles are mainly used to bear the overall force, but the overall force point is located at the bottom, and if the building is hit by external devices or natural disasters, it is easy to cause the piles to tilt phenomenon, which in turn leads to a certain impact on the overall building's compressive capacity, which in turn leads to certain economic losses and has certain dangers.
