Porous cast-in-place box culvert bottom plate and construction method

Abstract

The invention discloses a porous cast-in-place box culvert bottom plate and a construction method, and belongs to the technical field of concrete pouring. The method comprises the steps that 1, a reinforcement cage is bound, specifically, reinforcing steel bars are supported in an auxiliary mode through a reinforcement cage binding jig frame, the reinforcing steel bars are bound to form the reinforcement cage, and then the reinforcement cage binding jig frame is removed; 2, an outer side truss supporting rail moving side formwork is installed; 3, a hanging type anti-floating easily-disassembled inner side corner formwork is installed; 4, concrete pouring is conducted, specifically, the positions of the formworks on the two sides are adjusted, and then concrete pouring is conducted; and 5, form removal is conducted, specifically, after the strength of the poured concrete reaches the standard, the hanging type anti-floating easily-disassembled inner side corner form is removed. By reducing the binding difficulty of the box culvert reinforcement cage, the mounting and positioning precision of the porous box culvert bottom plate template is improved, and the construction quality and the construction efficiency of the porous cast-in-place box culvert bottom plate are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring, in particular to a bottom plate of a porous cast-in-place box culvert and a construction method. Background technique [0002] In the construction process of municipal engineering, the construction of box culvert reinforced concrete structure has always been a key part that restricts the construction period and reflects the construction quality. In the construction of traditional reinforced concrete box culvert structures, the cast-in-place concrete box culvert generally needs to be divided into multiple sections for construction, and the support is erected and removed once for each section. However, this method requires a lot of labor and construction The efficiency is low, the construction period is long, and there are great safety hazards. [0003] According to the construction requirements of municipal engineering in recent years, reinforced concrete box culvert structure projects o...
