Description

The modified and reinforced pressure water pipe of regenerating polypropylene

Technical field

The utility model is the modified and reinforced pressure water pipe of regenerating polypropylene (claiming the RPP.M gutter again), is used for row's rainwater, sewage, the combined sewage of urban municipal construction and building field.

Background technology

The drainage pipe that urban sewerage and drainage is at present used is used concrete reinforced pipe more.Because concrete reinforced pipe is very heavy, all make troubles for transportation and construction, high differential settlement ground with weak soil geology to underground water level is incompatible especially.Because it is the steel concrete pipe construction needs lifting appliance, bigger to construction environment and urban traffic influence.In addition, the reinforced concrete sewer pipe inner wall coarse, the coefficient of friction resistance is big, and corrosion-resistant causes application life short.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of regenerating polypropylene modified and reinforced pressure water pipe, to overcome the defective that prior art exists.

The technical scheme that its technical problem that solves the utility model adopts is: the branching pipe butt joint by same structure forms, and every joint branching pipe is formed by A mould pipe with same inner diameter and the butt joint of B mould pipe.Described two mould pipes, its two ends all have socket pipe, socket pipe respectively, and the surface of its body all is distributed with cyclic reinforcing rib; Surface in the socket pipe body end of B mould pipe is provided with seal groove; In the inner chamber of the socket pipe of the socket pipe insertion B mould pipe of A mould pipe, the two tight fit and sealing are connected as one.

The utlity model has in light weightly, the coefficient of friction resistance is little, and rigidity is big, and is corrosion-resistant, stretch-proof, and two pipe junction good seal performance, anti-wear performance is good, long service life, and to the less demanding advantage such as convenient of constructing again of execution conditions.

The specific embodiment

The utility model relates to the energy saving and environment friendly drainage pipe of row's rainwater that a kind of urban municipal construction and building field use, sewage, combined sewage, it is as base stock with discarded plastics, toughness reinforcing again, supercharging after processing and become RPP.M i.e. " special material of modified and reinforced die pressing product for regenerating polypropylene ", the polypropylene of making (RPP.M) mold pressing drainage pipe.

The utility model is described in further detail for following embodiment and accompanying drawing:

Structure of the present utility model is as shown in Figure 1, Figure 2, Figure 3 and Figure 4: the some joint branching pipes butt joints by same structure form, and every joint branching pipe is formed by A mould pipe 2 with same inner diameter and 1 butt joint of B mould pipe.Described two mould pipes, its two ends all have socket pipe, socket pipe respectively, and the surface of A mould pipe body 15 and B mould pipe body 16 all is distributed with several ringlike reinforcing rib 5 and a ring-type convex tendon 4, along the uniform arrangement of axis.Surface in the socket pipe 3 body ends of B mould pipe is provided with seal groove 8.In the inner chamber 7 of the socket pipe 6 of the socket pipe 14 insertion B mould pipes of A mould pipe, the two tight fit and sealing are connected as one.

A mould pipe of the present utility model and B mould pipe are assembling butt joints like this: earlier " O " type rubber seal 17 is put in the seal groove 8, coat sliding agent, then the socket pipe 14 of A mould pipe is aimed at socket pipe 6 afterburning insertions of B mould pipe, withstand the locating surface 7-1 of the inner chamber 7 of socket pipe 6 until the outer end of socket pipe 14 end face 13, the two closely cooperates, and 17 sealings of " O " type rubber seal are arranged, and make two pipe junctions non-leakage, constitute a joint branching pipe thus.

Above-mentioned branching pipe can be made by regenerating polypropylene modified plastics or other material that meets drainage requirement, is generally finished by manufacturer.Its technical data is generally: 0.2～1.5 meter of internal diameter, 1～2 meter of length; Or decide according to actual needs.

The butt joint that the utility model respectively saves between the branching pipe is to be formed by its adjacent socket pipe and socket pipe, finishes when generally being constructed by the user.Concrete method of attachment is: the socket pipe 3 of the B mould pipe of first segment gutter, its port one 1 by the socket pipe 10 of the A mould pipe of the second joint gutter stretches in the inner chamber 12, withstand the locating surface 12-1 of the inner chamber 12 of socket pipe 10 until the end face of socket pipe 3, the two inner junction constitutes being connected of the first segment and the second joint gutter thus by 17 sealings of " O " type rubber seal; And the like, until the designing requirement that reaches whole gutter length.

The utility model gutter tubing also can make full use of the performance characteristics of expanding with heat and contract with cold of plastics, and for example: it is two meter 1 joint that the tubing of DN1000mm is sold, and is divided into 1 meter 1 joint processing when the tubing of two meter one joint of processing.Promptly the effective length of (A mould pipe) pipe with bellmouth is that 1 meter actual (tube) length is 1.1 meters, and it is that 1 meter physical length is 1.14 meters that carrying spigots has the effective length of (B mould pipe) pipe of seal groove.The tail end of " A mould pipe " is that the bellmouth internal diameter that external diameter 1038mm length 100mm will insert in " B mould pipe " is (this material rate of expanding with heat and contract with cold is 13 ‰-15 ‰) in the 1025mm.The characteristic of utilizing this material to expand with heat and contract with cold is exactly done " A mould pipe " earlier and is cooled off naturally and do " B mould pipe " after 24 hours again and immediately cooled " A mould pipe " inserted in " B mould pipe " after " B mould pipe " demoulding.Tubing mechanical strength and the hot strength of such two meter 1 joint is with disposable to add two meter 1 tubing that saves of section chief the same.Naturally use after cooling off polypropylene welding rod to weld in junction again Deng the tubing that connects, both guaranteed that the junction is non-leakage, increased tensile strength again with 1 mitron by the electrical heating welding gun with material.The odds ratio that designs 1 meter long 1 joint will approach much with two meters long 1 tube walls that save shaping pipe of bore, because two meter 1 joint shaping pipe wall with bore approached, the plastic raw materials of heating does not just reach required mobile temperature at the die cavity tail end and just flows motionlessly in die cavity, and what work it out is the waste product tubing that is not fully filled die cavity.The cost of raw and processed materials of polypropylene of the present utility model like this (RPP.M) mold pressing tubing lacks than the moulding of two meter 1 joint, simultaneously, has increased the market competitiveness and the occupation rate of market of this tubing.
