Construction of concrete piles

Abstract

A construction method for concrete pile includes such steps as choosing the stratum with high loading-bearing power, forming a pile hole with predefined depth, constructing a pile in the pile hole, forming several pile holes surrounding said finished pile and with the depth which is shorter than that of said finished pile but 5-6 times greater than the diameter of said finished pile, and constructing the protective piles. Its advantages are high resistance to horizontal push force and less consumption of raw materials.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the construction technology of piles. Background technique [0002] With the development of my country's economic construction, there are more and more construction projects such as bridges, elevated railways, and high-rise buildings, and the requirements for the bearing capacity of piles in the foundation are also getting higher and higher. Horizontal thrust requirements are also getting higher and higher. In order to improve the horizontal thrust resistance of the pile, the method of increasing the pile diameter and the length of the pile is mainly used at present to increase the overall strength of the pile body to improve the horizontal thrust resistance of the pile, which invisibly increases the consumption of building materials and causes the construction cost. High, long construction period. [0003] According to the mechanical characteristics of the pile in the foundatio...

AI Technical Summary

Problems solved by technology

Then as long as the diameter of the pile body 5 to 6 times the pile diameter from the top of the pile is increased, that is, the strength of the pile body at the point of maximum stress is strengthened, the ability of the pile to resist horizontal thrust will naturally be improved, so it is not necessary to increase the pile body as a whole. Increased diameter to improve pile resistance to horizontal thrust
