Heavy-caliber reinforced concrete pipe pull-type opening alignment method

Abstract

The invention relates to a heavy-caliber reinforced concrete pipe pull-type opening alignment method. The method is characterized by including the following steps that a, a pipe installation longitudinal center line is formed on a reinforced concrete base plate (1) in a popping manner; b, a winch (2) is installed on the reinforced concrete base plate (1); c, a baffle (8) is installed at the crossing point of the pipe installation longitudinal center line formed in the popping manner and a transverse starting pint line of a first-section pipe (5); d, heel blocks (4) are symmetrically placed on the two sides of the pipe installation longitudinal center line formed in the popping manner; e, the first-section pipe (5) is hoisted by a crane to the concrete wedge-shaped heel blocks (4) to be in place; f, the pipe top elevation is rechecked; g, a second-section pipe (6) is hoisted to the concrete wedge-shaped heel blocks (4) to be in place; h, the step f is repeatedly executed; I, a steel wire rope (3) of the winch (2) penetrates the interior of the first-section pipe (5) and the interior of the second-section pipe (6); k, the step g to step j are repeatedly executed, and a next-section pipe is installed; and l, after pipe installation is completed, the winch (2) and the baffle (8) are dismounted, and a next work procedure is executed for construction. The heavy-caliber reinforced concrete pipe pull-type opening alignment method has the beneficial effects that pipe opening alignment is simple, and operation is easy and convenient.

Description

Technical field [0001] The invention relates to a pipeline installation method, in particular to a traction type matching method for large-diameter reinforced concrete pipelines. Background technique [0002] Large-diameter reinforced concrete pipes mainly refer to pipes with a diameter of Ф1000mm or more. At present, the largest diameter of reinforced concrete pipes produced in my country has reached Ф3500mm. They are mainly used for laying rainwater, sewage, irrigation and drainage and other gravity pipelines, and a small amount is used in road jacking projects. , It is widely used. [0003] The joint forms of large-diameter reinforced concrete pipes mainly include tongue-and-groove type, socket type and steel socket type. In the pipeline laying process, the pipeline counterpart is an important part of the laying. The quality of the counterpart directly affects the tightness of the joints, the elevation of the pipeline and the axis deviation. At present, cranes are usually used ...

AI Technical Summary

Problems solved by technology

At present, cranes are usually used to directly hoist the counterparts in China. This method has problems such as the joint ends of the pipe joints are not in place, the joints between the pipe joints are not tight, and the pipe elevation and axis deviation do not meet the requirements of the specifications. Water leakage often occurs during use, which affects The service life of the pipeline, in severe cases, will cause road surface subsidence, affecting pedestrian and driving safety
