A kind of technological method of drcp type pipe jacking regulating pipe

Abstract

The invention provides a process method for a DRCP type pipe jacking adjustment pipe, the method comprising the following steps: a. adding an adjustment pipe height bracket corresponding to the height in the molding cavity of the existing standard length molding die; b. Adjust the steel ring of the pipe socket to support and fix it in the forming cavity of the forming mold; c. By installing the locking force in the outer mold body, the steel ring hoop of the adjusting pipe socket is rounded to ensure the tightness of the steel ring of the regulating pipe socket The shape and position deviation of the working end face meets the working requirements; d. The inner wall of the outer mold body and the ring surface of the outer wall of the adjusting pipe socket steel ring are in contact to form a good seal, which can prevent annular water leakage and slurry leakage; e. At least one layer of double-sided adhesive is bonded to the inner circle of the end plate of the adjusting pipe socket along the peripheral surface. The invention rounds the outer wall of the steel ring of the adjusting pipe socket through the locking force when the outer mold body is closed, eliminating the need for adjusting the pipe socket. The steel ring is deformed, and the installation of a seal on the inner wall of the outer mold body can effectively prevent the occurrence of annular water leakage and slurry leakage in the regulating pipe.

Description

technical field [0001] The invention relates to the technical field of forming technology of reinforced concrete pipe jacking regulating pipes for jacking construction, in particular to a process method of DRCP type pipe jacking regulating pipes. Background technique [0002] Reinforced concrete drainage pipes for jacking construction method (hereinafter referred to as jacking pipes) are reinforced concrete pipe products that are connected end to end in the underground by means of trenchless construction and continuous jacking construction to form underground pipelines (or pipe galleries). It has been widely used in pipeline projects crossing roads, rivers, railways, etc., as well as urban buildings. In the process of pipeline jacking, the general method is to place the pipes that exceed the actual pipeline length first between the working pit and the receiving pit. Realize the penetration of the pipeline, and then use manual or mechanical means to cut off or destroy the exc...

[0002] Reinforced concrete drainage pipes for jacking construction method (hereinafter referred to as jacking pipes) are reinforced concrete pipe products that are connected end to end in the underground by means of trenchless construction and continuous jacking construction to form underground pipelines (or pipe galleries). It has been widely used in pipeline projects crossing roads, rivers, railways, etc., as well as urban buildings. In the process of pipeline jacking, the general method is to place the pipes that exceed the actual pipeline length first between the working pit and the receiving pit. Realize the penetration of the pipeline, and then use manual or mechanical means to cut off or destroy the excess concrete pipe body exposed at the hole. Since the jacking pipe is a reinforced concrete structure with high strength and large pipe size, it is difficult to install in such a space as a working pit. In a narrow place, it will be very difficult to cut and remove the redundant concrete pipe body, time-consuming and labor-intensive, and the safety factor of the workers is low. Therefore, in order to respond to the actual length of the engineering pipeline in the field construction, the production It is imperative to produce adjusting pipes of different lengths that can match the length of the pipeline
