Method for rapidly constructing light formwork of reinforced-concrete-cast-in-place circular draining inspection well

Abstract

The invention discloses a method for rapidly constructing a light formwork of a reinforced-concrete-cast-in-place circular draining inspection well. The method includes the following construction steps that the inner formwork is installed; reinforcing steel bars of the inspection well are completely bound, and casting of bottom plate concrete is completed; the side boundary of the inner formwork is correctly defined on a concrete bottom plate, holes are drilled in the inner side of the well wall along the side boundary through an electric drill, reinforcing steel bar heads are inserted, and four reinforcing steel bar heads are perpendicularly inserted along the center and used for positioning the position of the inner formwork; the inner formwork is formed by two semicircular light wood formwork bodies, the two semicircular light wood formwork bodies are spliced into a circle on a flat plane, and opposite pulling is carried out with twine tighteners along oppositely-supported positions of the perpendicular abutted seam; after being externally assembled completely, the inner formwork is manually carried and placed into a well chamber and fixed. According to the method, the semicircular light wood formwork bodies are prefabricated and manually carried and installed on site, construction of the draining inspection well is rapid, and the formwork of the reinforced-concrete-cast-in-place circular draining inspection well is formed by splicing steel formwork bodies or narrow-strip wood formwork bodies.

Description

technical field

[0001] The invention relates to the field of reinforced concrete cast-in-place drainage inspection wells, in particular to a method for quickly constructing lightweight templates for reinforced concrete cast-in-situ circular drainage inspection wells. Background technique

[0002] Generally, municipal reinforced concrete cast-in-place circular drainage inspection wells are spliced ​​with steel formwork or narrow strip wooden formwork. The steel formwork has a large weight and cannot be transported manually. It needs the cooperation of hoisting machinery, which is inconvenient to splice and install; the wooden formwork is cut into narrow strips and assembled into a circle. Shaped formwork, large joints, easy to cause slurry leakage, and the geometric size is not easy to control.

[0003] With the acceleration of urban and rural construction in our country, the problem of environmental pollution is also more serious. In order to prevent sewage leakage in the m...
