Abstract

The invention relates to the field of civil engineering, in particular to an impact holing super-long cast-in-situ bored pile and a construction method. The construction method comprises the following steps of building a drilling platform, mounting a steel casing, performing drilling construction, performing holing inspection and slag removal treatment, binding a reinforcement cage, performing mounting construction and performing concrete pouring. The construction method is used for solving the construction problem of the impact holing super-long cast-in-situ bored pile, meets the requirements of structural construction, effectively reduces the engineering cost, accelerates the construction speed, and can obtain better technical and economic benefits when being applied to actual engineering.

Description

technical field [0001] The invention relates to the field of civil engineering, and more particularly relates to an impact hole-forming super-long bored pile and a construction method. Background technique [0002] With the continuous development of the scale of highway construction in my country, the total mileage of highway bridges continues to increase. During the construction of highway bridges, due to the influence of various factors such as superstructure, load properties, and hydrogeological conditions, the span of bridges continues to increase; To improve the bearing capacity of the bridge foundation, the pile diameter and pile length of the bridge pile foundation are correspondingly required to be larger and larger. Therefore, a large number of large-diameter and super-long bored piles have appeared in the project. [0003] At present, the construction of conventional ultra-long bored piles has problems such as the large area of ​​the construction platform occupied b...
