Description
Technical field
The utility model relates to a kind of manhole.
Background technology
Prefabricated cement block manhole: prefabricated cement block manhole major defect is heavy; difficulty of construction is large; execution conditions require high; maintenance is difficult for; the particularly main of manhole access; the bore of arm, quantity, direction; the changing factor of absolute altitude is many; be difficult to realize plant layoutization and produce solution, therefore, be difficult to extensive use in little municipal administration and one residential; China applies experience repeatedly repeatedly in many cities; fail really to promote, its reason is except cost factor always, and main still macro environment is not enough to support extensive use.
Fiberglass sand inclusion manhole: fiber glass reinforced plastics inspection well is the manhole of preparing with glass fiber reinforced unsaturated polyester resin based composites, compare with traditional material, the advantage such as that fiber glass reinforced plastics inspection well has is lightweight, corrosion-resistant, easy for installation, long service life.Some Domestic unit is studied and tests fiber glass reinforced plastics inspection well, also successfully manufactures experimently out a collection of fiber glass reinforced plastics inspection well and applied on market.But because fiber glass reinforced plastics inspection well is to carry out secondary perforate connection after adopting glass fiber reinforced plastic wound tube moulding again, on-the-spot manual connection is very difficult, the waste of material that perforate is got off is not recyclable, so production efficiency is low, chute weak effect, junction shearing force is very low, add after unsaturated polyester resin crosslinking curing, the material that perforate is got off is difficult to reclaim, so it is high to cause very large waste of material and price to occupy, is also not suitable with environmental requirement.In addition, glass fiber reinforced plastics product is larger to workman's injury in process of production, and labour protection problem is serious.These factors are enough to cause fiber glass reinforced plastics inspection well to use in limited range.
Welding is wound around and rotational molding technique manhole: adopt thermoplastic rotation molding, external exploitation early.Key industry is used high density polyethylene (HDPE) (HDPE), polyvinyl chloride (PVC) material, adopt spiral winding and welding, rotational molding technique, production can divide field fabrication and two kinds of methods of prefabrication, advantage is energy-conserving and environment-protective, lightweight, corrosion-resistant, discharge performance is good, long service life, solved especially the switching performance of pipeline and well, good airproof performance, has avoided underground water source secondary pollution.Shortcoming is that site prefabrication has certain environmental requirement, speed is slow, cycle is long, the problems such as the artificial property of welding procedure safety factor, the technique of current domestic rotational moulding inspection well because of cost drop into very little, approximately 1,500,000 RMB just can put into production, and large-scale injection moulding company drops into all more than 50,000,000, can imagine that rotomoulded articles just splices the slightly better manufacture craft of manhole than manual being welded.Cannot compare far away with mold pressing, injection moulding manhole, be applicable to the microminiature enterprise that financial strength is limited, technical level is not high and make plastic inspection well.Subject matter: " with low content of technology, " " product wall unevenness is even ", " not high, the fine and closely woven bubble of product density is many ", " the product process-cycle is longer; thus be unsuitable for producing in enormous quantities ", " bottom designed arc-shaped appearance defect, building site install can not put steady ", " perforate when mounted of arm socket, increase difficulty of construction and hidden leakage defect ", " pipeline reducing diameter needs welding gun welding gap; operating personnel are had to particular/special requirement, is difficult to spread and uses ".
Once injection moulding plastic inspection well: this well feature is made up of well seat, pit shaft, well lid and accessory.Sewage inspection well is provided with guiding gutter, and rainwater inspection well is provided with the shape of mud sinking chamber structure.All well seats are all disposable mold pressing, injection mo(u)lding, welding technique.Combination is in the use installed very convenient quick, and pit shaft can directly measure intercepting at the scene according to absolute altitude, and overall performance is high.Subject matter is: the production technology of disposable injection-moulded plastic manhole determines that each assembly must adopt a mold, and the injection machine that must be equipped with equivalent pressure just can complete, and therefore, meet above condition and have three large problems in China.(1) disposable injection moulding manhole sets foot in two large industry, Mould Machining and plastic cement manufacturing industry.Generally plastic cement manufacturing enterprise impotentia mold developing, and mold manufacturing industry does not relate to plastic products manufacture, therefore relatively disconnect technically, though be related but not tight, have certain distance, particularly in mould development, lack can referential technical data for disposable plastic manhole, the time of having researched and developed because of the cycle long, have a big risk, therefore two large industry large scale investments exist sight property.(2) want to improve product specification, its kind is too many, drops into hugely, and the people's no fund that forms understanding technology and market drops into, and the people who has fund not understand technology and market dare not drop into.(3) injection moulding well is thermoplastic, this kind manhole performance issue is can not low temperature resistant >-5 DEG C and high temperature <70 DEG C, and weatherability is poor, and northern area can not be used (to the north of the Yellow River), intensity and stiffness are low, and application life is short.The cost of raw material is high, so price comparison is high.
