Problems solved by technology

The present invention can solve the shortcomings of non-excavation repair technologies such as pipeline spraying: 1. The density of the inner lining layer is insufficient after spraying repair; 2. The space of the inspection well is narrow and cannot be wiped after spraying repair, resulting in uneven inner lining; 3. The sprayed inner lining does not form a skeleton structure, and the structure of the inspection well cannot be reinforced; 4. Before spraying and repairing, the connecting pipes of the inspection well need to be blocked and water diverted

Abstract

The invention provides an inspection well trenchless reparation device and a reparation method thereof, and belongs to the field of municipal construction. The device includes an airbag, and the airbag includes a main airbag arranged vertically, and a flow guide airbag vertically connected with the bottom of the main airbag. A plurality groups of cushion block groups are evenly arranged on the outer wall of the main airbag along the longitudinal and circumferential ranges, each group of cushion block groups includes at least one cushion block connected together in a bonding mode, a slurry injecting pipe fixing hole is formed in the cushion block, a slurry injecting pipe is connected in the slurry injection pipe fixing hole in a bonding mode, a plurality of slurry injecting holes are formedin the slurry injecting pipe, and slurry injecting is carried out in the slurry injecting pipe. The invention further provides an inspection well trenchless reparation method of the reparation device, and the method can solve the defects that 1 the compactness of a lining layer after spraying reparation is insufficient; 2 the space of an inspection well is narrow, and the inspection well cannot be troweled after the spraying reparation so that the lining layer is not level; 3 a skeleton structure is not formed in a spraying lining layer, and the inspection well structure cannot be reinforced;and 4 a connecting pipeline of the inspection well is subjected to blocking and water transferring before the spraying reparation.

Description

Technical field [0001] The invention belongs to the technical field of municipal construction, and in particular relates to an inspection well non-excavation repair device and a repair method thereof. Background technique [0002] Due to the high amount of corrosive gas in the inspection well and improper operation and maintenance, the brickwork or prefabricated inspection well has serious corrosion, leakage and other defects, which not only affects the normal use of the inspection well, but also easily leads to accidents such as ground collapse around the inspection well. occur. In view of defects such as corrosion and leakage of inspection wells, the industry's solutions to such problems include the excavation of new inspection wells or the repair of inspection wells by spraying. Both have the following defects: [0003] Excavation and new construction: 1. Excavation and construction will not only cause social and environmental impacts, but also cause serious traffic congestion ...
