Abstract
The utility model discloses a kind of pressure-resistant corrosion-resisting flexible joint for underground plastic drainage pipeline, the joint includes flexible steel in flat section tubing and two section support tubes, flexible steel in flat section tubing is elastic rubber pipe, its both ends is socketed on drainpipe respectively, the support tube is hard polyethylene chloride tube, it is arranged on inside flexible steel in flat section tubing, support tube is identical with the external diameter of drainpipe, regulation gap is provided between support tube and drainpipe and between two section support tubes, the device pressure-resistant corrosion-resisting, convenience quick for installation, can solve because the differential settlement of drainpipe periphery soil layer makes pipeline be caused its crackle or even the phenomenon being broken by detrusion, avoid the generation of draining seepage accident, it is simple in construction, it is easily achieved.
Description
Technical field
Subsurface drainage field is the utility model is related to, a kind of specially resistance to compression for underground plastic drainage pipeline is resistance to
Corrode flexible joint.Belong to drainage pipeline accessories field.
Background technology
With the development of China's urban and rural health building cause, plastic drain-pipe is because with light inexpensive and corrosion resistant feature
It is widely used in domestic hygiene drainage system.
At present, as sanitary apparatus in junction chamber and outdoor lower well or the rigidity plastics pipeline of septic tank, plastic draining
In use when its periphery soil layer differential settlement, pipeline is deformed by longitudinal shear to be caused its crackle or even is broken pipe,
Because these problems all occur at underground concealed position, it is difficult to find, when draining, seepage accident will be produced in underground.
People's generally use two kinds of basic fundamentals solve the above problems.A kind of technology is only with material systems such as rubber tubes
Into flexible steel in flat section tubing as joint, although the joint can solve when drainpipe periphery soil layer is uneven heavy to a certain extent
Caused pipeline crack or phenomenon of rupture during drop, but because this kind of joint flexible steel in flat section tubing be easy to by its periphery soil to
Interior crimp, prevent draining from unimpeded.Another method is using a kind of flexible joint of built-in steel-wire carcass, this kind of joint
Built-in steel-wire carcass although there is supporting role, it is well known that sanitary sewage mostly has acid-base property or contains salt, steel wire
Long period of soaking rots corrosion and avalanche in this Sewage Environment, most loses draining work(such as the result of former technique at last
Can, these are all physical presence and urgent problem.
Utility model content
The purpose of this utility model is to provide a kind of pressure-resistant corrosion-resisting flexible joint for underground plastic drainage pipeline,
Solve the problems, such as proposed in background technology.
To solve the above problems, the utility model provides following technical scheme：It is a kind of for underground plastic drainage pipeline
Pressure-resistant corrosion-resisting flexible joint, the joint include flexible steel in flat section tubing and two section support tubes, and flexible steel in flat section tubing is elastic rubber pipe, its
Both ends are socketed on drainpipe respectively, and the support tube is hard polyethylene chloride tube, is arranged on inside flexible steel in flat section tubing, support tube
It is identical with the external diameter of drainpipe, it is provided with regulation gap between support tube and drainpipe and between two section support tubes.
Compared with prior art, the beneficial effects of the utility model are as follows：
1. the utility model, by setting two section support tubes in flexible steel in flat section tubing, between support tube and drainpipe and two save
Regulation gap is provided between support tube, adds the freedom of movement of joint, can effectively be overcome because of drainage pipeline periphery soil
The differential settlement of layer, pipeline is set to be caused its crackle even phenomenon of rupture to be occurred by detrusion.
2. the utility model by flexible steel in flat section tubing set two section support tubes and be provided with regulation gap, support tube with
It is also equipped with adjusting gap between drainpipe, while the joint bigger freedom of movement of offer is provided, soil layer butt joint can be resisted
Radial pressure, avoid the radial deformation phenomenon of flexible steel in flat section tubing, ensure the smooth circulation of draining.
3. support tube of the present utility model is hard polyethylene chloride tube, there is the characteristics of intensity highly corrosion resistant, overcome existing
There is the drawbacks of using steel-wire carcass not corrosion-resistant within a fitting in technology, improve the service life of joint, service life and row
Water pipe is synchronous.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 to Fig. 2 is referred to, the utility model provides a kind of technical scheme：It is a kind of for underground plastic drainage pipeline
Pressure-resistant corrosion-resisting flexible joint, the joint include flexible steel in flat section tubing 2 and two and save support tube 4, and flexible steel in flat section tubing 2 is elastic caoutchouc
Pipe, its both ends are socketed on drainpipe 1 respectively, and the support tube 4 is hard polyethylene chloride tube, is arranged in flexible steel in flat section tubing 2
Portion, support tube 4 is identical with the external diameter of drainpipe 1, and regulation is provided between support tube 4 and drainpipe 1 and between two section support tubes 4
Gap 3.
Use process：Outside flexible steel in flat section tubing 2 serves good undertaking and made during the use of whole drainpipe 1
With the support tube 4 inside flexible steel in flat section tubing 2 is dual tube designs, adds durability and the switchover capability of a variety of radians, is secondly propped up
There is regulation gap 3 in the gap that stay tube 4 is set, flexibly crooked radian can be adjusted, further increase flexibility and connect
The service efficiency of head, then drainpipe 1 is external diameter 110mm, wall thickness 3.2mm hard polyethylene chloride tube, is intercepted from drainpipe 1
Two segment length are that 5cm pipe makes support tube 4, and support tube 4 is placed in into internal diameter 106mm, wall thickness in 6mm standard silicone rubbers pipe
Portion, the two regulation gaps saved between support tubes 4 are 2cm, and the both ends of flexible silicone rubber pipe are socketed on drainpipe 1 respectively, are covered
Spreading degree 15cm, the gap for making drainpipe 1 and support tube 4 is 2cm, and flexible joint can realize 20 ° of bendings, work well, and is made
Convenient and quick construction, when buried depth of pipeline is 1.8 meters, support tube is indeformable.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
