Abstract
The utility model discloses a be used for prosthetic synchronous compound butt joint hose of drainage pipe, including interface, basic unit and compound barrier layer in the basic unit, it is regional that the hose connector both ends are equipped with the meshing, just the hose bonds into the tube -shape through the meshing, uses and glues the seam crossing with the consistent membrane strip cover barrier layer of barrier layer material, utilizes hot -pressing composite's mode, with the synchronous hot -pressing composite of the two -layer material in the interior outside. Hose connector adopts engagement means to bond, and each layer seam can stagger, and is synchronous compound, can avoid stress concentration in the problem of seam crossing, is favorable to the upset construction.
Description
Technical field
The utility model belongs to drainage pipeline and repairs field, more particularly to a kind of synchronization for drainage pipeline reparation is combined
Docking flexible pipe.
Background technology
Increasing with urban development to infrastructure needs amount, the total amount of China's underground piping rapid growth in recent years,
Each city has formed densely covered sewer system.The existing water supply in the whole nation, draining, combustion gas and heat supply this 4 class municipal administration basis set
Apply underground utilities length and surpassed 1,720,000 kilometers, at present still with annual 100000 kilometers of speed increase.Currently, China's underground piping
Net situation allows of no optimist, and structural and feature disease is serious, run, drip, leak generally existing, the ground that piping disease is caused
Collapse and happen occasionally, annual rainy season, municipal drainage is not smooth, cause ponding serious, traffic is blocked, to urban construction and people's lives
Make troubles, or even harm the people's lives and property safety.
At present, when domestic tubular nonwoven compound material makes, first with non-weaving cloth as skeleton, antiseepage is uniformly coated
Film, is prepared into plane non-weaving cloth composite material；Then the width of non-weaving cloth composite material is docking together,
Can be made into tubular nonwoven compound material.To being connected to 2 kinds of modes, one is suture；Two is heat pressure adhesive.The tubulose of suture is non-
Woven cloths composite, the thickness of its seam crossing is 2 times of other parts thickness, and when lining is actually turned over, the suture of seam crossing holds
It is easily broken off by concentrated stress, and sewing needle will not only pierce through the non-weaving cloth of softness during suture, also pierce through harder
Antiseepage film, causes suture relatively difficult, sutures inefficient, while seam crossing can produce many pinpricks, particularly turns over lining construction
Afterwards, pinprick can deformed in tension and expansion, leave seepage hidden danger and influence sealing, typically up to less than the anti-gas permeability of composite,
Anti- water penetration and when turning over lining mechanical property requirement.In addition, the tubular nonwoven compound material of heat pressure adhesive, its interface exists
Soaked for a long time in water, easily cracking, it is also difficult to reach the anti-gas permeability of composite, the requirement of anti-water penetration.
Utility model content
To solve the above problems, it is soft that the utility model provides a kind of compound docking of the synchronization for drainage pipeline reparation
Pipe, it can effectively solve the problems, such as that liner hose interface is run into using suture or heat pressure adhesive etc..
To achieve the above object, the utility model provides following technical scheme：It is a kind of for drainage pipeline repair it is same
The compound docking flexible pipe of step, including interface, basic unit and the impervious barrier that is compounded in basic unit, it is characterised in that：The hose connection two
End is provided with mesh regional, and the flexible pipe is bonded into tubular by engagement.
The impervious barrier of the mesh regional, basic unit are respectively adopted upper and lower docking mode connection.
The thickness of the mesh regional impervious barrier is equal, and the thickness of the mesh regional basic unit is less than the flexible pipe basic unit
Thickness.
The basic unit is non-woven fabrics, and the impervious barrier is polyurethane film.
The length of the mesh regional is 5-10cm.
The flexible pipe also includes antiseepage film bar, and the antiseepage film bar is on the impervious barrier seam.
The bonding of the mesh regional non-woven substrate uses non-woven fabrics glue special, the mesh regional polyurethane barrier
The bonding of layer uses polyurethane film glue special, the film bar to use polyurethane film special glue with the bonding of polyurethane barrier layer
Water.
Compared with prior art, the beneficial effects of the utility model are：(1) hose connection described in the utility model is used and nibbled
Conjunction mode is connected, and each layer interface staggers connection, keeps the material of main part of interface consistent, can avoid the problem of stress concentration, meanwhile,
Each layer interface connection is respectively adopted special adhesive, improves its adhesion efficiency and flexible pipe sealing；(2) polyurethane film impervious barrier
Interface is provided with polyurethane film bar, can improve the waterproof and barrier properties of hose connection, there is provided its sealing.

Specific embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of compound docking of synchronization for drainage pipeline reparation of the utility model offer is soft
Pipe, including interface, basic unit and the impervious barrier that is compounded in basic unit, it is characterised in that：The hose connection two ends are provided with region of engagement
Domain, and the flexible pipe is bonded into tubular by engagement.
The impervious barrier of the mesh regional, basic unit are respectively adopted upper and lower docking mode connection.
The thickness of the mesh regional impervious barrier is equal, and the thickness of the mesh regional basic unit is less than the flexible pipe basic unit
Thickness.
The basic unit is non-woven fabrics, and the impervious barrier is polyurethane film.
The length of the mesh regional is 5-10cm.
The flexible pipe also includes antiseepage film bar, and the antiseepage film bar is on the impervious barrier seam.
The bonding of the mesh regional non-woven substrate uses non-woven fabrics glue special, the mesh regional polyurethane barrier
The bonding of layer uses polyurethane film glue special, the film bar to use polyurethane film special glue with the bonding of polyurethane barrier layer
Water.
Further, a kind of manufacturing process steps of convertible liner hose are as follows：
(1) polyurethane barrier tunic and non-woven substrate are combined by the tape casting, and region of engagement is reserved at interface two ends
Domain；
