Embodiment Construction

[0022] The construction method of the concrete pile that is made up of 3 piles as an embodiment of the present invention, it comprises the following steps, at first, as figure 1 As shown in a, according to the geological exploration report and the load on the upper part of the building, a better foundation soil is selected as the bearing layer at the pile end, and the hole is formed after the pile position is selected on the foundation; then, as figure 1 As shown in b, the pile hole 1 is formed according to the design depth; then, as figure 1 As shown in c, a reinforcement cage 2 is placed in the pile hole 1, and concrete 3 is poured to form a central stressed pile 4; after that, as figure 1 As shown in d, a hole is formed close to the central force-bearing pile, and the depth of the hole is less than the length of the pile body of the central force-bearing pile, and greater than 5 to 6 times the pile diameter of the central force-bearing pile; then, as figure 1 As shown in e...

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...
