A support device for inspection well lining repair

Abstract

A supporting device used for inspection well liner repair is used for supporting a repair piece and comprises a blocking section portion and a supporting portion used for supporting the blocking section portion. The blocking section portion is a circular component; the supporting portion comprises a reinforcing piece, a longitudinal supporting piece, a transverse supporting piece and a supporting base used for supporting and fixing the transverse supporting piece, the reinforcing piece, the longitudinal supporting piece, the transverse supporting piece and the supporting base are sequentially arranged, the supporting base is arranged on the inner wall of an inspection well in a supporting mode and is connected with the transverse supporting piece through an inner spiral piece in a screwing mode, the distance between the inner spiral piece and the transverse supporting piece is adjustable, the end of the reinforcing piece is set to be telescopic, and the reinforcing piece is matched with an inner spiral structure between the supporting base and the transverse supporting piece through the telescopic end of the reinforcing piece, so that the whole supporting portion can be adjusted in a self-adaptive mode so as to be adapted to different pipe diameters, and the longitudinal supporting piece, and the transverse supporting piece and the supporting base can support the circular component together. The supporting device used for inspection well liner repair can be adapted to operations of inspection wells with different pipe diameters automatically, is simple in structure and convenient to use and saves operation cost.

Description

technical field [0001] The invention belongs to the field of municipal drainage construction equipment, and in particular relates to a supporting device for repairing the lining of an inspection well. Background technique [0002] In the past, when repairing the inner lining of urban underground inspection wells, in order to prevent the soft inner lining material from sinking at the mouth of the inspection well when repairing the inner lining of the inspection well, bricks were used at the inner mouth of the pipeline. Build a brick wall block by block to support the lining repair materials. Bricks, cement, yellow sand and other materials need to be used. After building, it will take 2-3 days of maintenance before the inspection well lining can be repaired. Remove after repair. Bricks, cement, yellow sand, etc. used for brick seals are all disposable, which wastes resources. After demolition, a large amount of construction waste will be generated, polluting the environment, ...

AI Technical Summary

Problems solved by technology

Bricks, cement, yellow sand, etc. used for brick seals are all one-time use, which wastes resources. After demolition, a large amount of construction waste will be generated, polluting the environment, brick seals need time for maintenance, and delay the progress of the project.

[0003] If airbags are used to block, due to the chemical reaction of the lining material during the inspection well lining repair construction, a large amount of heat will be generated. The high temperature will increase the pressure in the airbag and may burn the airbag, resulting in the explosion of the airbag and engineering accidents.
