Background
At present, inspection wells generally applied to rainwater pipelines, sewage pipelines and various pipelines are mostly built by cement or bricks, and the connection method between the inspection wells and the pipelines mainly comprises butt joint slurry sealing or large and small sleeve joint. Pipelines and inspection wells built by the materials and the technology are easy to be damaged by collapse, cracking, breaking and the like, and the service life of the structure is short; in addition, the method also has the problems of long construction period, low efficiency, high cost, easy environmental pollution and the like. With the development of national infrastructure, corrugated steel is increasingly applied to construction of traffic engineering, municipal engineering, hydraulic engineering, military engineering and the like due to the advantages of excellent physical and mechanical properties, high construction efficiency, wide application range, strong environmental friendliness, good economic benefit and the like. In recent years, an attempt to put corrugated steel materials into the construction of inspection wells and underground pipelines is also made, but as the application history of corrugated steel in China is short, the corresponding technology is still in an immature stage, and serialization, standardization and standardization are lacked, so that the application of the corrugated steel at present is far from achieving the excellent performance and effect of the corrugated steel materials, even a certain loss is caused, and the application of the corrugated steel is influenced, and the problem lies in the connection form of the corrugated steel structures.
The existing corrugated steel inspection well has the following defects and shortcomings:
(1) inspection well lid and well cover are directly withheld and are circled at the corrugated steel wall of a well for thereby the well lid is directly passed to the corrugated steel pipe wall with pressure when receiving to roll and is caused the inspection well wall of a well to warp and sink, and further, the pressure that the wall of a well receives can directly transmit pipeline and junction in the pit, causes the pipeline to warp and break, and the well lid also can damage because the atress is inhomogeneous in addition.
(2) The corrugated steel inspection well wall and the pipeline are connected in a pipe orifice butt joint mode, irregular and rough welding seams are easily formed during welding due to the fact that the waveform and the radian of the pipe wall and the wall of the well are different, the quality of the welding seams of the type of the interface is poor, the strength is weak, and the corrugated steel inspection well wall and the pipeline are prone to fracture and leakage due to collision and cantilever concentrated bending stress in the construction and use processes.
(3) In addition to the pipe orifice butt joint, the flange butt joint is also one of the connection methods which are commonly adopted, but the rigid butt joint of the flanges forms stress concentration so as to generate crack fracture and leakage.
Based on the structure, the invention designs a novel corrugated steel inspection well structure and a construction method to solve the problems.
