Treatment and construction method of super-pouring pile head

Abstract

The invention discloses a treatment and construction method of a super-pouring pile head. A reinforcement cage is manufactured, and the reinforcement cage comprises a main body reinforced bar and a spiral reinforced bar, wherein the main body reinforced bar comprises a plurality of longitudinal reinforced bars which are mutually parallel to each other, are vertically distributed on the same circumference at equal intervals and are encircled to form a columnar structure; the spiral reinforced bar is spirally circled on the outer side of the columnar structure formed by encircling the pluralityof longitudinal reinforced bars; the top parts of the longitudinal reinforced bars are bent to separately form first bending reinforced bars and second bending reinforced bars; a sleeve is sleeved onthe columnar structure formed by the second bending reinforced bars; and the reinforcement cage is put in a pile hole, drilling is carried out and then concrete is poured, the reinforcement cage is annularly cut to the position of the sleeve after the concrete is condensed to a certain extent, the annularly-cut pile head is removed, and the first bending reinforcement is drawn out of the concrete.According to the treatment and construction method of the super-pouring pile head disclosed by the invention, the construction strength is reduced, the construction cost is reduced, the constructionnoise is reduced, the construction period is shortened, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a construction method for overfilling pile heads. Background technique [0002] Pile is an ancient craft, which has played an important role in the construction of ancient houses and bridges. With the development of the times, piles made of reinforced concrete are widely used in modern buildings. Modern pile foundations are divided into prefabricated piles and cast-in-situ piles according to the construction method. Among them, bored cast-in-place piles have small deformation and good stability under the action of earthquake force, and can effectively solve the weak foundation in earthquake areas and the earthquake resistance of liquefied foundations. And is widely used. [0003] In the construction of modern architectural soil engineering, bridge soil engineering, municipal engineering, water conservancy engineering, etc., pile foundations are generally adopted, so high requirement...

AI Technical Summary

Problems solved by technology

[0004] At present, the construction of super-filled pile head and the effective pile length are carried out at the same time without any other measures. The construction of removing the pile head generally adopts the method of pneumatic pick and manual hard chisel, which leads to high noise in the later operation process, low construction efficiency, and poor quality of pile head removal. It is obviously poor; especially for the removal of pile heads with a large amount of work, there is obviously a shortage of labor force, and the construction cost increases, which seriously affects the progress of the construction period and the goal of safe and civilized construction
