Municipal underground pipeline partition construction device

Abstract

A municipal underground pipeline partition construction device comprises a left clamping plate, a right clamping plate and an air bag ring, wherein the left clamping plate and the right clamping plate are symmetrically arranged left and right, and the air bag ring is located between the left clamping plate and the right clamping plate. The center of the air bag ring is provided with a center hole. The center of the right end of the left clamping plate is provided with a left sleeve of which an opening faces towards the right clamping plate. The center of the left end surface of the right clamping plate is provided with a right sleeve of which an opening faces towards the left clamping plate. The left sleeve and the right sleeve both extend into the center hole. The left sleeve is further internally provided with a sliding ring groove extending left and right. The right end of the sliding ring groove is provided with a communicating groove communicating with the sliding ring groove. A sliding sleeve is slidably installed in the sliding ring groove. The left sleeve penetrates through the communicating groove and is fixedly connected with the sliding sleeve. The left clamping plate and the right clamping plate are internally provided with a left driving assembly and a right driving assembly correspondingly. An abrasion-resistant rubber cushion ring is fixedly arranged in the position, located on the left-right symmetrical axis, of the outer wall of the air bag ring.

Description

technical field [0001] The invention relates to the field of municipal construction, in particular to a municipal underground pipeline partition construction device. Background technique [0002] Under the municipal roads, various pipes are often installed, such as drainage pipes, sewage pipes, etc. These underground pipes are generally buried underground during the construction of municipal roads. However, during long-term use, cracks will appear in the underground pipes, especially It is at the joint of two pipelines. Therefore, cracks will appear in the underground pipeline, and construction personnel need to perform welding seam treatment. Since the pipeline is buried underground, construction personnel need to drill into the pipeline to complete the welding seam treatment. For seam construction, construction personnel need to cut off the flow before drilling into the pipeline, but the pipeline is generally fluid, so it cannot be stopped immediately after the cut is comp...

[0002] Under the municipal roads, various pipes are often installed, such as drainage pipes, sewage pipes, etc. These underground pipes are generally buried underground during the construction of municipal roads. However, during long-term use, cracks will appear in the underground pipes, especially It is at the joint of two pipelines. Therefore, cracks will appear in the underground pipeline, and construction personnel need to perform welding seam treatment. Since the pipeline is buried underground, construction personnel need to drill into the pipeline to complete the welding seam treatment. For seam construction, construction personnel need to cut off the flow before drilling into the pipeline, but the pipeline is generally fluid, so it cannot be stopped immediately after the cut is completed, and there will still be fluid, so that the welding seam construction cannot be carried out in time, and If the gate valve for cutting off is accidentally opened during weld construction, construction personnel are prone to accidents, so there is a great safety hazard during weld construction
