Description
Technical field
The utility model relates to seal correlative technology field, more particularly to one kind connects for prefabricated mixed mud piping lane spigot-and-socket
The compound wedge-shaped sealing strip of the water-swellable of mouth.
Background technique
Sealing strip is for being sealed between connection object, preventing from leaking, realizing closed common component.Existing sealing
Part is usually to utilize elasticity caused by the elasticity (such as elastic rubber) or seal configuration design of material, makes sealing element in object
Linkage interface generates flexible deformation, is filled, blocks to the gap of object linkage interface, realizes the purpose of sealing.
Currently, since precast concrete pipe gallery bell socket waterproof product is generally wedge-type seal item, only a kind of bullet
Property material, the problem of will appear seal failure after product breakage or long-time service, product service life is not grown.And it is prefabricated mixed
In assembly, piping lane surface mixed mud and sealing strip need to compress and rub solidifying soil piping lane bell socket, can generate larger resistance
Power, so that assembling construction difficulty is big.
Utility model content
To solve the above problems, the utility model provides a kind of compound wedge-shaped sealing strip of water-swellable, which is met
The water expansion compensation sealing performance of sealing strip, extends the service life of sealing strip, and structure is simple, and assembling construction is easy.

Further ground preferred embodiment can also be set in the body interior along the perforation extension of sealing strip length direction
Through-hole.The seal pressure of sealing strip, increases the elastic deformation space of sealing strip when design through-hole can further optimize installation,
Make installation is more convenient to be easy.
Further, the second outer convex globoidal is formed with the described first outer convex globoidal corresponding section in the water-swellable layer,
The first outer convex globoidal is connect with the described second outer convex globoidal rounding off, forms the outer convex globoidal of a semicircle.In ontology
The upper end being connected with water-swellable layer is designed to convex globoidal outside semicircle, is also the installation for facilitating sealing strip, reduces sealing strip
With the frictional force on precast concrete pipe gallery surface.
The utility model has the following beneficial effects:
1, in the present solution, using elastic rubber material as weatherstrip body, and it is compound equipped with water-swellable on the body
Layer, makes sealing strip that can be entrenched in concrete pipe gallery interface effective sealed interface after compression；Water is met because water-swellable layer has
Expansion, absorb water the automatic healing compensation sealing function of expansion repeatedly repeatedly, caused by can preventing because ontology breakage, deformation being used for a long time
Seal failure extends the service life of sealing strip.
2, precast concrete pipe gallery bell socket piping lane surface concrete and sealing strip in assembly needs to compress and rub
It wipes, biggish frictional resistance can be generated, in chamfered portion design water-swellable layer, installation in surface spray water, water-swellable
Layer absorbs the water of sprinkling, forms the surface with lubricating action, can effectively reduce between piping lane surface concrete and sealing strip
Frictional resistance is conducive to assembling construction.
3, the through-hole that weatherstrip body side design inner concave arc surface and body interior design perforation extend, during installation to close
Strip of paper used for sealing applies certain pressure, and sealing strip can get bigger flexible deformation, so that sealing strip is easily installed；In addition, sealing
The semicircle outer convex globoidal of upper design, can effectively reduce frictional resistance, facilitate installing and using for sealing strip.
