Structure and Construction Method for Controlling Cracks in Side Wall of Underground Structure

Abstract

The invention discloses a structure for controlling underground structure side wall cracks, comprising a concrete wall body internally provided with a structural reinforcing mesh, a steel barrel and baffles ; a deformation joint is longitudinally arranged at the concrete wall body; the steel barrel is provided with the deformation joint, the deformation joint is located in the steel barrel, the steel barrel is filled with concrete, the barrel walls on the left side and the right side of the steel barrel are connected with the concrete wall on two sides of the deformation joint to form a whole,the barrel wall on the front side and the rear side of the steel barrel extends out of the concrete wall, and the steel barrel is fixedly connected with the structural reinforcing mesh; and the baffles are fixedly arranged on the left side and the right side of the steel barrel respectively and are perpendicular to the deformation joint. According to the structure, a structural steel bar frame isfixedly connected with the steel barrel, the baffles are used for connecting concrete inside and outside the steel barrel, the steel barrel and the concrete are connected into a whole, and the overall strength and rigidity are improved. The overall safety of the structure is not damaged by insufficient strength or rigidity at the deformation joint position. Construction is simple and convenient,and implementation is convenient.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a structure for controlling cracks in side walls of underground structures and a construction method thereof. Background technique [0002] The existing concrete often produces cracks during construction and use. The main reason for the cracking is the temperature stress caused by the temperature difference between the inside and outside of the concrete; the shrinkage stress caused by the shrinkage of the concrete during the setting and hardening process and the structure often restricts its shrinkage; the tensile strength of the concrete is insufficient. (Affected by its material itself, construction mix ratio, reinforcement situation, maintenance conditions, construction quality and other factors). At present, the principle of crack control is to reduce the temperature difference between the inside and outside of the concrete, optimize the material to reduce its shrinkage, ...
