Method and manufacturing method based on reinforced concrete special-shaped pipe culvert design

Abstract

The invention discloses a reinforced concrete special-shaped pipe culvert design method and manufacturing, and relates to the field of reinforced concrete special-shaped pipe culvert design and production. According to the internal force distribution condition, constructional bars are arranged in the left side and the right side of the inner wall of a pipe culvert, the constructional bars are arranged on the upper side and the lower side of the outer wall of the pipe culvert, and the constructional bars are arranged on the left side and the right side of the outer wall of the pipe culvert according to internal force; structural bars are arranged on the upper side and the lower side of the inner wall of the pipe culvert according to internal force, the compressive property of concrete and the tensile property of steel bars are fully exerted, and the structural bars and the length size in the circumferential direction are determined according to structural design. By adjusting the shape of the bottom of the pipe culvert, the concentration ratio of foundation counterforce is weakened, the trend is uniform, the internal force of the pipe culvert is changed, the maximum bending moment of the bottom of the pipe is reduced, and the internal force is adjusted structurally; the bottom plate and the side plate for prefabricating the concrete foundation in a factory ensure the product quality and realize batch production; the construction period of a pipe culvert construction site is shortened, and the safety risk caused by the fact that the groove cannot be backfilled for a long time is reduced.

Description

technical field [0001] The invention relates to the field of design, production and installation of reinforced concrete special-shaped pipe culverts, in particular to a method and manufacture based on the design of reinforced concrete special-shaped pipe culverts. Background technique [0002] With the continuous improvement of national infrastructure, a large number of applications of reinforced concrete and prestressed reinforced concrete pipes and culverts, the goal of energy conservation and environmental protection has been vigorously promoted in the country. The amount of cement, sand, gravel and steel bars is very large. How to further develop technological inventions The role of the material can be fully exerted, thereby saving the amount of material and further reducing the consumption of high energy-consuming industries, which has become a field that can make a difference. [0003] However, the existing reinforced concrete pipe culverts are generally designed and a...

Problems solved by technology

[0003] However, the existing reinforced concrete pipe culverts are ordinary and conventional reinforcement design and configuration methods, which are generally circular or elliptical, evenly and symmetrically arranged, and there is a large waste of reinforcement configuration in parts with small internal forces.

[0004] In the current reinforced concrete pipe culverts, the ordinary pipe body is generally round, oval or flat-bottomed, and the pipe body is round or has a partial straight section. There is no adjustment of the internal force to reduce the internal force, and the internal force cannot be realized. The effect of relatively uniform distribution; ordinary pipe culverts adopt the method of pouring concrete on the construction site, the construction period is too long, and the pipe culvert trenches are placed for too long, which brings about disadvantages such as reduced benefits, complicated construction organization and landslides
