Abstract
The utility model relates to a double-wall corrugated pipe with bilayer wall spigot-and socket mouth, which consists of an inner-layer straight pipe and an outer-layer corrugated pipe of the double walls; wherein, corrugated pipe is fixedly adhered to the outer surface of the straight pipe; one end of the straight pipe is an end-expansion pipe socket; the corrugated pipe extends to the pipe socket, taking a corresponding shape of that of the pipe socket, and is fixedly adhered to the outer surface of the pipe socket; the other end of the straight pipe is a spigot; the outer surface diameter of the socket is smaller than or equal to that of the wave crest at the middle piece of the corrugated pipe; the wave crest outer surface diameter at one end of the spigot is smaller than or equal to the internal diameter of the socket and the wave crest at the spigot is provided with a sunk groove embeddable into an elastic seal ring. The utility model has the advantages of that: seal ring materials are substantially saved due to identical outer diameters of socket and pipe material, thereby lowering much manufacture cost; equal product size and height during manufacture and storage is convenient for transportation and storage and easy to be stacked in order; with the end-expansion pipe socket pipe distortion is avoided, surely guaranteeing product sealing performance after construction.
Description
[technical field]
The utility model relates to a kind of pipe configuration, the particularly a kind of high density polyethylene (HDPE) with dual-layer wall joint socket (HDPE) double-wall corrugated pipe that is applied to sewer or rainwater that buries ground.
[background technique]
At present, the collection of municipal sewage treatment and rainwater has been the strategic emphasis of the national economic development.Buried drain pipe comprises sewage pipe and row's rainwater pipe.Drainage pipeline networks mainly adopts cheapest concrete pipe or concrete reinforced pipe.Because its life-span short (only less than is 20 years), connect not tight, sealing is poor, bury the uneven settlement of ground soil in addition, the place of being tightly connected is gone to pot, causes effluent seepage, severe contamination environment and underground water, the concrete pipe leakage can reach more than 30% in the municipal sewage pipe network according to statistics, and this phenomenon has become the big public hazards in the modern city life.In addition, concrete duct construction inconvenience, operating expenses height.At present, because new type plastic pipe has in light weight, advantages such as intensity is high, easy construction, materials province, the fields such as electric sheath, construction drainage, municipal drainage, field irrigation that are widely used in communicating by letter, and will progressively replace the waste pipe of traditional material.
In the prior art, a kind of polyethylene double-wall corrugated pipe with double-walled unification bellmouth is arranged, comprise straight tube and the bellmouth of being located at the straight tube end.This straight tube is made of dual-layer wall, and its internal layer is smooth straight tube; Skin is the bellows on the outer surface that fits in the internal layer smooth straight; This bellmouth is the double-walled unification bellmouth that is made of internal layer bellmouth and outer bellmouth.That this polyethylene double-wall corrugated pipe has is in light weight, the characteristics of simple installation, wear-resistant, corrosion-resistant, long service life, can be widely used in fields such as municipal engineering, environmental protection, agricultural drainage and irrigation, expressway, railway, electric power, communication and discharge of industrial wastes.But because due to its structure, the seal ring volume of use is bigger, needs cost of material higher; In addition,, be difficult for neat the stacking or transportation, cause the distortion of enlarging easily, influence the sealability after product is constructed in the production of product, when handing over the storehouse.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of double-wall corrugated pipe with dual-layer wall joint socket is provided.
The utility model has adopted following technical proposal to solve its technical problem: a kind of dual-layer wall joint socket double-wall corrugated pipe, comprise double walled internal layer straight tube and outer bellows, this bellows fixedly fits in the outer surface of straight tube, straight tube one end is the bellmouth of enlarging, bellows extends to this straight tube socket and is and the corresponding shape of this bellmouth, and fixedly fit in outer surface with this straight tube socket, the other end of straight tube is a socket, it is characterized in that: the outer surface diameter of this bellmouth is smaller or equal to crest outer surface diameter on the bellows stage casing, crest outer surface diameter on socket one end is smaller or equal to the socket internal diameter, and is equipped with the groove to the embedded elastic seal ring of lower recess on the crest of spigot.
The ring stiffness height that the utility model is had except general high density polyethylene (HDPE) dual-layer wall joint socket double-wall corrugated pipe, the impact strength height, not cracky is installed in transportation, long service life, connect the sealing ne-leakage, the engineering comprehensive cost is not higher than outside the advantages such as cement pipe, because the utility model is consistent the external diameter of bellmouth and the external diameter of tubing, make the utility model save sealing ring material in a large number, thereby greatly reduce manufacture cost, and producing, when handing over the storehouse, the size height of product is consistent, be very easy to stack neat, transportation, store very convenient, its enlarging of pipeline can not cause distortion, has guaranteed the sealability after product is constructed really.

Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model joint socket after being connected;
The local amplification view of A portion among Fig. 3 Fig. 2.
Each sequence number is expressed as respectively among the figure:
1-straight tube 2-bellows 3-bellmouth
4-socket 5-crest 6-elastic seal ring
The 7-groove
D-bellmouth outer surface diameter d-bellows stage casing crest outer surface diameter
Crest outer surface diameter f-socket internal diameter on the F-socket
[embodiment]
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
With reference to Fig. 1, the utility model comprises double walled internal layer straight tube 1 and outer bellows 2, this bellows 2 fixedly fits in the outer surface of straight tube 1, one end of straight tube 1 is the bellmouth 3 of enlarging, bellows 2 extends to these straight tube bellmouth 3 places and is and this bellmouth 3 corresponding shapes, and fixedly fitting in outer surface with these straight tube bellmouth 3 places, the other end of straight tube is a socket 4
The outer surface diameter D of bellmouth 3 described in the utility model is smaller or equal to crest outer surface diameter d on the bellows stage casing, crest outer surface diameter F on socket one end is smaller or equal to socket internal diameter f, and is equipped with the groove 7 to the embedded elastic seal ring 6 of lower recess on the crest 5 at socket 4 places.
The crest 5 of above-mentioned socket 4 places one end can be a plurality of, but is equipped with two at least, and all is equipped with the groove 7 to the embedded elastic seal ring 6 of lower recess on each crest 5.
With reference to Fig. 2 and Fig. 3, during the utility model engineering construction elastic seal ring 6 is embedded groove 7, the dual-layer wall socket with pipeline inserts bellmouth then, realizes that spigot and socket type flexibly connects method, has solved the masty problem that is tightly connected of general large-bore plastics waste pipe.The utility model is pressed in it and is all reached more than the 0.15MPa through connecting leakage test.
Total engineering cost of the present utility model can be lower than traditional concrete pipe, reduces about 30% than the cost of faucet concrete pipe, and construction period can shorten greatly, and has good economic benefit.
