Concrete prefabricated culvert pipe processing method

Abstract

A concrete prefabricated culvert pipe processing method comprises the steps that S1, a steel reinforcement framework is manufactured, transverse steel reinforcements are annularly distributed in a seam welder according to the actual size of the inner diameter of a ring reinforcement of the steel reinforcement framework to be manufactured, the ends of the transverse steel reinforcements are limited through a limiting machine, longitudinal steel reinforcements are welded to the outer surfaces of the transverse steel reinforcements through the seam welder, and the steel reinforcement framework is manufactured; S2, mold assembling is conducted; S3, concrete is prepared; S4, pipe manufacturing is performed; and S5, demolding and curing are carried out. The limiting machine is arranged to limit the ends of the transverse steel reinforcements and keep the transverse steel reinforcements in a horizontal state, so that the limiting machine is matched with the seam welder to enable the longitudinal steel reinforcements and the transverse steel reinforcements to be welded, the diameter of the steel reinforcement framework obtained through welding is unchanged, and the steel reinforcement framework can be used for manufacturing culvert pipes. Moreover, through limitation of the ends of the transverse steel reinforcements by the limiting machine, the relative displacement between the transverse steel reinforcements is not changed, the limiting precision requirement is met, and the limiting operation can be continuously kept.

Description

technical field [0001] The invention belongs to the technical field of concrete culvert pipes, in particular to a processing method for concrete prefabricated culvert pipes. Background technique [0002] Culvert pipe refers to a kind of pipeline buried below the surface, which is cast with reinforced concrete, commonly known as cement pipe, and is generally used as a water pipeline. Generally, the culvert pipes are prefabricated, and then sent to the construction site for laying. When processing the culvert pipes, the steel skeleton is first made, and then concrete is poured into the steel skeleton. Or mechanical welding, but both of the above two methods need to place the horizontal reinforcement evenly in a circle first, and then weld the longitudinal reinforcement to the horizontal reinforcement. Since the horizontal reinforcement has a certain length, it is necessary to manually adjust the horizontal reinforcement to keep the horizontal reinforcement. In order to ensure...

Problems solved by technology

Generally, the culvert pipes are prefabricated and then sent to the construction site for laying. When processing the culvert pipes, the steel skeleton is firstly made, and then concrete is poured into the steel skeleton. After forming, the culvert pipe preparation is completed. When making the steel skeleton, manual welding is generally used Or mechanical welding, but both of the above two methods need to place the horizontal reinforcement evenly in a circle first, and then weld the longitudinal reinforcement to the horizontal reinforcement. Since the horizontal reinforcement has a certain length, it is necessary to manually adjust the horizontal reinforcement to keep the horizontal reinforcement. In order to ensure that the longitudinal steel bars are welded to the outer surface of the horizontal steel bars and the diameter of the steel frame remains unchanged, on the one hand, manual adjustment is required, and on the other hand, the accuracy of manual adjustment is not enough. If the level of the horizontal steel bars cannot be maintained, the diameter of the steel frame will change. , if the range of change is large, the concrete placed on the surface of the steel skeleton cannot completely wrap the steel skeleton, or the diameter of the culvert will be affected by the increase of the thickness of the concrete, which will directly affect the preparation of the culvert
