Abstract

The utility model discloses a composite corrosion-resistant reinforced concrete drainage connecting pipe. The main body of the connecting pipe is a concrete or reinforced concrete hollow pipe body, the two ends of the pipe body are provided with a spigot and a bell and spigot, and the pipe bodies are in spigot connection by the port; the utility model is characterized in that the spigot and the bell and spigot on the two ends are coated with corrosion-resistant rubber, the spigot of the pipe body is inserted into the bell and spigot of the other pipe body, all the contact surfaces are in elastic contact of the rubber and the rubber, and a rubber seal ring is arranged between the spigot and the bell and spigot. The design effectively solves the problems that the traditional reinforced concrete drainage connecting pipe is easy to corrode, damage and leak, and has the advantages of high rigid strength, large compression-resistant load, good sealability, large extent of the pipe base deformation-resistance, good corrosion-resistant performance, long service life, simple and convenient laying construction and the like.

Description

A kind of reinforced concrete drainage connecting pipe of composite anti-corrosive

Technical field

The utility model relates to the technical field of municipal administration, agricultural water supply and sewerage pipeline, is the drainage connecting pipe of matrix with concrete, reinforced concrete particularly.

Background technique

At present, traditional concrete pipe or the concrete reinforced pipe of the many employings of municipal or agricultural supplying drainage, these water supply and sewerage pipelines directly come into operation after by concrete or reinforced concrete moulding by casting, because the intrinsic material behavior behind the concrete formation, port connection between its tube and tube is rigidly connected basically, only be provided with seal ring in the port joint, this single seal ring sealing, gap between the interface tube is bigger, poor sealing performance, occur the seepage phenomenon easily, cause the very stiff and demanding ground of interface tube damaged because of pipeline foundation distortion also very easily, cracking, seepage.On the other hand, concrete decay resistance is relatively poor, and during especially as drainage pipeline, easily by acid and alkali corrosion, the gap at pipe joint place is easier the corrosion just, makes generally be no more than 20 years the working life of pipeline.Though and the plastic pipe decay resistance better, good airproof performance, fatal defective is poor, the rigidity intensity difference of its resistance to compression weight bearing power, as easy as rolling off a log pressurized and breakage.Therefore, the structure of traditional concrete or the reinforced concrete drainage connecting pipe raising that haves much room for improvement.

The model utility content

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, proposes that a kind of rigidity intensity height, resistance to compression load are big, good seal performance, strong, the anti-pipeline foundation amplitude of deformation of corrosion resistance are big, the reinforced concrete drainage connecting pipe of the composite anti-corrosive of long service life.

The purpose of this utility model is achieved by the following technical solution: a kind of reinforced concrete drainage connecting pipe of composite anti-corrosive, main body is the hollow body of concrete or reinforced concrete, the two ends of hollow body form socket and joint socket respectively, insert to hold by port between body and the body and be connected, it is characterized in that: all posted antiseptic rubber on the socket at each hollow body two ends and the joint socket, the body socket inserts the joint socket of another body, all surface of contact all are Elastic Contact of rubber and rubber, and also are provided with rubber seal between socket and the joint socket.Further, for guaranteeing the sealing of pipe joint, the antiseptic rubber of hollow body port posts and extends to inboard wall of tube body, and the inwall seam crossing between two body sockets and joint socket has posted sealing corrosion rubber in addition again.Particularly, its thickness of the antiseptic rubber that posts is 0.5--5mm.

She Ji linkage structure has tangible advantage like this:

1, body adopts concrete or reinforced concrete, and rigidity intensity height, resistance to compression load are big, and each port is with in adopting antiseptic rubber, body to be connected with body to be just and is softened, and forms flexible sealing with seal ring.

2, the body port forms the sealing of three levels of end face, inner and outer surface and seam, and anti-pipeline foundation amplitude of deformation is big, has solved the leakage problems of conventional art effectively.

3, adopt antiseptic rubber, acidproof, alkaline-resisting, anticorrosive property, impervious good reaches more than 50 years working life.

4, constructing operation is extremely easy, quick, and the labor intensity that connects is installed is reduced greatly, the cost performance height, soundness is good, is easy to again safeguard, and the segmentation mounting or dismounting are very convenient.

Embodiment

Embodiment one, referring to Fig. 1 one Fig. 2, the main body of the municipal drainage connecting tube of the composite anti-corrosive of present embodiment is a reinforced concrete hollow body 1, the two ends of hollow body 1 are shaped to respectively can insert each other to hold and connect stepped shaft socket 11 and the joint socket 12 that cooperates, and specialization is that the end face and the surface of the socket 11 of hollow body 1 have posted antiseptic rubber 2; The end face of joint socket 12 and surface have also posted antiseptic rubber 2, and antiseptic rubber 2 extends to the inwall of hollow body 1 in the lump.When two hollow bodys connect, cover one rubber seal 4 on socket 11, body socket 11 inserts the joint socket 12 of another body, contact with end face until end face, making all surface of contact all is Elastic Contact of rubber and rubber, at last, the seam crossing between socket 11 and joint socket 12 posts in addition again and is bonded with sealing corrosion rubber 21.Like this, body and body are connected to form the sealing of three levels, first level be mouth of pipe inside and outside wall with rubber seal 4 between " rubber-seal ring-rubber " contact; Second level is that joint socket 12 contacts with socket 11 end faces " rubber-rubber "; Tri-layer is the sealing corrosion rubber 21 of inwall seam crossing.Wherein the thickness of antiseptic rubber 2 is 1.2mm, and the thickness of sealing corrosion rubber 21 is 1.5mm.

Embodiment two, referring to Fig. 3-Fig. 4, the structure of present embodiment and embodiment one are roughly the same, just the main body of waste pipe adopts concrete hollow body 3, and the socket 31 of hollow body 3 is different with the form of joint socket 32, has adopted the structure that is tightly connected that two body front/rear ends contact, the centre is provided with seal ring 4.Inwall seam crossing between socket 31 and the joint socket 32 has posted sealing corrosion rubber 21 again, and antiseptic rubber 2, sealing corrosion rubber 21 are identical rubber.In the present embodiment, antiseptic rubber can be selected the high molecular polymer rubber of liquid state for use, adopts the mode that applies to post, be bonded on the body, its smooth surface, even after the dried solid moulding.

Certainly, only enumerated two kinds of preferred implementation here, in fact, the shape of body, structure etc. can change in response to the needs of practice of construction laying, and the protection category that these are equal to, varied configurations roughly the same all should belong to this patent repeats no more here.
