Concrete moulding bed structure and pouring method

Abstract

The invention discloses a concrete moulding bed structure and a pouring method, belonging to the treatment before pouring of concrete on the foundation in the building construction. The invention aims to solve the problems frequently occurred in the existing common brick moulding bed construction that a great quantity of clay bricks are needed, one-time moulding cannot be realized and a great quantity of backfill is needed after the completion of the construction. The invention provides a structure and pouring method which are time-saving, labor-saving and are beneficial to the environmental protection. The concrete moulding bed structure provided by the invention is composed of a concretemoulding bed, a foundation pit outer wall and a moulding bed foundation pit inner wall, wherein the concrete moulding bed is formed by pouring along the foundation pit outer wall and molded in the longitudinal direction, and the concrete tie shuttering tightly contacts the foundation pit outer wall. The pouring method of the concrete moulding bed structure provided by the invention comprises the steps of performing earth excavation, performing foundation pit dewatering, setting up a concrete moulding bed inner side formwork, pouring the concrete moulding bed, removing the formwork and the like.

Description

technical field [0001] The invention relates to reinforcement of building foundation pits, in particular to foundation tire molds. Background technique [0002] At present, in the process of building construction, brick tire molds are often used. This processing method is simpler and more economical than other methods. However, the processing method of the brick tire mold itself also has some disadvantages. [0003] Brick tire formwork first needs to build bricks in the foundation pit. Since construction workers need to go down the foundation pit to build bricks, a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the construction of these brick tire molds is completed, a large gap will inevitably be formed between the brick tire molds and the outer wall of the foundation pit, thereby requiring a large amount of backfill, which greatly wastes manpower and material resources, increases the constructi...

However, the processing method of the brick tire mold itself also has some disadvantages

[0003] Brick tire formwork first needs to build bricks in the foundation pit. Since construction workers need to go down the foundation pit to build bricks, a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the construction of these brick tire molds is completed, a large gap will inevitably be formed between the brick tire molds and the outer wall of the foundation pit, thus requiring a large amount of backfill soil, which greatly wastes manpower and material resources, increases the construction procedure, and delays the construction time.

From this point of view, the brick tire mold itself is a processing method with many processes, a large workload, and cannot be formed at one time.

In addition, the brick tire mold requires a large amount of clay bricks, which will cause great harm to the environment
