The prefabricated assembly-type reinforced concrete inspection well has the advantages that connecting joints of the lower well chamber, the upper well chamber and the cover plate are flexible tongue-and-grooves, the well chambers are connected with a pipeline through flexible tongue-and-grooves, the flexible joints are sealed by rubber rings, rigid tongue-and-grooves are sealed by cement mortar, the well chambers and the pipeline are connected by both rigid joints and flexible joints, and the well chambers are connected with the pipeline by pipes not larger than 1000mm, so that when the pipeline differentially settles, joint breakaway or pipeline breakage can be effectively avoided; a bottom plate is prefabricated together with the prefabricated lower well chamber during production, so that a construction seam is reduced, integrity of the inspection well is increased, operating safety of the pipeline is improved, and floating resistance of the inspection well is improved.
Description
Technical field
The invention belongs to a kind of underground structure, particularly a kind of underground reinforced concrete pipiline prefabricated assembling type reinforced concrete prefabricated units and manufacture method.
Background technology
Existing various underground pipeline manholes all adopt loam brick to build by laying bricks or stones and finish: 1, its intensity is low, and speed of application is slow, easy to leak, poor durability, and application life is short, is unfavorable for that the Three Eastern Provinces use coldly.2, the loam brick manhole is formed by brick masonry, and is difficult fully non-leakage, adds northeast cold ground freeze injury, and effluent seepage polluted underground water resource does not meet environmental protection policy.3, fired clay brick uses loam brick to cause the clay resource waste in a large number.4, the field operation time long, the wet trade workload is large, curing time is long, the long period can not backfill, the construction period is long, even environment and constructor's life security around threatening.5, only be example take Beijing, more than 200 kilometers in annual about newly-built pipeline need be built more than 10000 of various pipe manholes, uses loam brick more than 2,500,000.Country also prohibites and uses loam brick as building material at present, and it is imperative to carry out in this case the prefabricated assembling type reinforced concrete manhole.
At present, the domestic application concrete inspection well substitutes brick masonry manhole product, mainly contains prefabricated assembling type reinforced concrete manhole and building-brick type concrete masonry units manhole, also has cast in situs steel concrete manhole.The prefabricated assembling type reinforced concrete manhole has intensity height, assemblingization rapid construction and the tight characteristics of seam, can fundamentally solve the shortcoming of loam brick manhole, thereby can make manhole reach the advantages such as bearing capacity is large, non-leakage, speed of application is fast.Building-brick type concrete masonry units manhole, just solution is never used the loam brick problem, and building-brick type concrete masonry units manhole and cast in situs steel concrete manhole fundamentally do not solve other problems.The prefabricated assembling type reinforced concrete manhole is that current application is the most extensive, a kind of urban construction duct products that development prospect is best.
Summary of the invention
Purpose of the present invention is just providing a kind of assembling manhole that can realize suitability for industrialized production, the technical problem of instead of clay brick masonry manhole.Make its assembling flexibly, constructability.Thereby safety and the compliance of various conduit runnings have been improved.
The technical scheme of the prefabricated assembled manhole of the present invention: by the prefabricated chamber of going into the well, prefabricated upper well chamber, prefabricated pit shaft, interface is linked to be integral body from bottom to top, and the well room cover plate is arranged between well chamber and the pit shaft, is equipped with cover plate, well lid on the pit shaft, it is characterized in that:
The shape of above-mentioned prefabricated assembling type reinforced concrete manhole has circle, rectangle.
Above-mentioned circular pit shaft is to connect prefabricated regulating block below the prefabricated cover plate, and prefabricated pit shaft, cover plate connecting interface are the rigidity tongue and groove, cover plate and well lid connection reservation anchor bolt;
Above-mentioned (circle) prefabricated chamber of going into the well, prefabricated upper well chamber, prefabricated cover plate connecting interface are flexible tongue and grooves, and (rectangle) prefabricated well chamber, prefabricated well room cover plate connecting interface are the rigidity tongue and grooves.It is flexible tongue and groove that (rectangle) prefabricated well chamber is connected with pipeline.
Above-mentioned prefabricated upper well chamber, the chamber of going into the well, well room cover plate, pit shaft, cover plate have the lifting hole(eyelet) of reservation.
Above-mentioned interface is sealed with cement mortar by the rigidity tongue and groove, flexible interface wedge-shaped rubber rubber sealing.
Marking time of above-mentioned prefabricated well chamber and shaft in wall is to reserve mark time position, hole or the pre-buried parts of marking time.
The material of the above-mentioned prefabricated chamber of going into the well, upper well chamber, cover plate, pit shaft, walling crib is C30 steel concrete.
Above-mentioned prefabricated well chamber is the connected mode that rigid interface and flexible interface combine with being connected of pipeline, prefabricated well chamber connecting pipe connects with being not more than 1000mm tubing, therefore when pipeline generation differential settlement, can effectively avoid occuring the phenomenon of interface disengaging or pipeline break.Be not failure of pipeline, thereby improve the conduit running safety.
Above-mentioned circle (rectangle) well chamber is formed by connecting by prefabricated upper well chamber, the prefabricated chamber of going into the well, wherein be reserved with wellhole on the prefabricated well room cover plate, have the preformed hole connecting pipe uses in the prefabricated chamber of going into the well, it is prefabricated together base plate when the prefabricated chamber of going into the well produces, reduce constuction joint one, increase the manhole globality, improved manhole anti-floating ability.
Prefabricated assembling type reinforced concrete manhole of the present invention is with advanced Core Vibrated Casting Process production, and production efficiency is high.
Beneficial effect: the prefabricated assembling type reinforced concrete manhole is finished by reinforced concrete prefabricated, and well chamber and pit shaft are regulated by different moduluses and be assembled, and it is supporting with various pipeline, the rapid construction of realization pipeline assemblingization.The prefabricated assembling type reinforced concrete manhole does not use loam brick, is conducive to protection of the environment.Fast than brick masonry manhole speed of application, quality is high, compressive resistance is high, can stand rolling of heavy-duty machinery, is conducive to the problem of subsiding of solving road well chamber.Advantage with intensity height, antiseep, frost resistance, corrosion resistance are all high than loam brick, thereby have prolonged application life, can satisfy design standard and construction requirement.The construction of manhole is become fast, simple, save lay bricks, jointing.Wipe one's face, the precipitation operation, improved greatly labor productivity and operating efficiency, accelerated the cycle of infrastructure construction.The manhole that can be widely used in various coal gas, water, electricity, heating line.
