Abstract
The utility model relates to a polypropylene molded drainpipe with the structure that the drainpipe is generated by a first molded pipe (1) socket with a second molded pipe (2), the socket position is seal connected by welding method, then a drainpipe with a faucet at one end and a jack at the other end is generated, a seal ring groove (8) is arranged at the jack and ring reinforced ribs (5) are uniformly arranged on the circumferential surface of the drainpipe. The utility model has the advantages of light weight, small coefficient of frictional resistance, great hardness, corrosion prevention, stretch-proofing, good seal performance at the joint of the two pipes, great anti-wear performance, long utilizing life, low demand of execution conditions, convenient construction and the like.
Description
Technical field
The utility model is polypropylene mold pressing gutter (claiming the PP-R 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 polypropylene mold pressing gutter, to overcome the defective that prior art exists.
The technical scheme that its technical problem that solves the utility model adopts is: formed by the first mold pressing pipe with same inner diameter and the second mold pressing pipe socket joint, the socket joint position is tightly connected by welding manner, constituting an end thus has bellmouth, the other end that a gutter of socket is arranged, this socket is provided with seal groove, is evenly distributed with cyclic reinforcing rib on the side face of this gutter.
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.

Fig. 3 is the structural representation of the second mold pressing pipe 2 of the present utility model.
Fig. 4 is the enlarged diagram of first mold pressing pipe 1 of the present utility model and the second mold pressing pipe, 2 socket joint states.
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 PP-R i.e. " special material of modified and reinforced die pressing product for regenerating polypropylene ", the polypropylene mold pressing gutter of making.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Structure of the present utility model is as shown in Figure 1, Figure 2, Figure 3 and Figure 4: formed by first mold pressing pipe 1 with same inner diameter and the second mold pressing pipe, 2 socket joints, the socket joint position is tightly connected by welding manner, constituting an end thus has bellmouth, the other end that a gutter of socket is arranged, this socket is provided with seal groove 8, is evenly distributed with several ringlike reinforcing rib 5 (see figure 1)s on the side face of this gutter.
Above-mentioned gutter can be made by regenerating polypropylene modified plastics or other material that meets drainage requirement, is generally finished by manufacturer.Its technical data is decided according to actual needs, and the parameter of the serial gutter product that present embodiment provides is: length is 1～2 meter; Thickness of pipe wall is 3～8 millimeters; Nominal diameter is 200～1350 millimeters, for example 200,225,300,400,500,600,700,800,900,1000,1100,1200,1350 millimeters etc.
Installation of the present utility model is generally finished by user's construction.For example, first gutter and second gutter are such socket joint assemblings: earlier " O " type rubber seal 12 is embedded in the seal groove 8, coat sliding agent, then the socket pipe 3 of first gutter is aimed at socket pipe 6 afterburning insertions of second gutter, withstand the locating surface 7-1 of the inner chamber 7 of socket pipe 6 until the end face of socket pipe 9, the two closely cooperates, and 12 sealings of " O " type rubber seal are arranged, and makes two pipe junctions non-leakage.The rest may be inferred, just can form drainage pipe (connected mode is seen Fig. 4) between two inspection shafts.
Claims (5)
1. polypropylene mold pressing gutter, it is characterized in that forming by the first mold pressing pipe (1) with same inner diameter and second mold pressing pipe (2) socket joint, the socket joint position is tightly connected by welding manner, constituting an end thus has bellmouth, the other end that a gutter of socket is arranged, this socket is provided with seal groove (8), is evenly distributed with cyclic reinforcing rib (5) on the side face of this gutter.
2. polypropylene mold pressing gutter according to claim 1 is characterized in that: the nominal diameter of every gutter is 200～1350 millimeters, and length is 1～2 meter.
3. polypropylene mold pressing gutter according to claim 1 and 2 is characterized in that: the thickness of pipe wall of every gutter is 3～8 millimeters.
4. polypropylene mold pressing gutter according to claim 1 is characterized in that: when two gutters were installed, its socket joint junction was tightly connected by the mode that " O " type rubber seal embeds in the seal groove (8).
5. polypropylene mold pressing gutter according to claim 1 is characterized in that: described gutter is made by the poly-interior alkene modified plastics of regeneration.
