Description
Technical field
The present invention relates to the linkage field of plastic inspection well seat and pipeline, refer more particularly to and be convenient to the bell and spigot that pipeline is connected with manhole and the well seat with this bell and spigot.
Background technology
Manhole is for rain sewage vent line, the vertical shaft that underground utilities position is built at a certain distance, in order to connect the pipeline use of different tube diameters, different directions, differing heights, main confession maintainer people makes regular check on dredging pipeline, removes mud foreign matter, prevents line clogging etc., is one of urban road underground foundation facility.
Due to plastic drain-pipe and plastic inspection well lightweight, corrosion-resistant, pipe ring stiffness can design as required, sealing joint is good, non-leakage, effectively can prevent the pollution to underground water, and speed of application, hydraulics, cost performance etc. are all better than cement sewer pipe and the brick manhole of sand-lime, therefore use in a large number in the rain sewage drainage system such as town road, one residential.What the well seat part of plastic inspection well adopted mostly is disposable rotation molding, reaches the connection changing caliber and angle with accessories such as reducing joint, angle joint and rubber seal.Bell mouth of plastic inspection well is the undertaking pipe fitting that manhole connects different tube diameters, different directions, differing heights pipeline, should be connected, be connected again with plastic conduit with manhole well seat.Pit shaft, the connection of entering (going out) waterpipe and well seat adopt the flexible bayonet joint of rubber seal or heat shrinking sleeve to connect, the angle change among a small circle can be adapted to, convenient and quick construction, good seal performance, antiseep, effectively preventing the secondary pollution to underground water, is a kind of environmental protection and energy saving building materials.Bellmouth is connected with manhole well seat and is mostly Integratively formed structure and flange connection.
In existing technology, bell and spigot is all integrated, when adopting the bayonet joint of rubber seal flexibility, is difficult to be inserted in bell and spigot by pipeline opening, especially for corrugated conduit; In addition, pipeline just to backfill after all pipelines such as Shi Shi and well seat are completed laying, so after well seat and pipeline connect, pipeline may be made to be moved due to the operation of next well seat, thus affects the sealing that a well seat is connected with pipeline; Moreover the well seat of prior art and pipeline not easily split in the later stage, be not easy to the maintenance in later stage.
Through retrieval, Chinese patent application publication No.: CN102168431A, denomination of invention is: manhole, and it comprises well head, pit shaft and well body, and described well head is located at described upper wellbore, and described lower wellbore is located at described well body, and wherein, described well body is Split type structure.By well body is designed to Split type structure, this application case is easy to manufacture, cost reduces, and at the construction field (site), be convenient to and pipeline assembling, process complexity reduces, but does not consider the sealing of manhole well seat in this application case, after the segmentation of well body, the sealing of whole well body can not ensure, the steadiness that pipeline is connected with well seat is not too high.
