Description
Technical field
The utility model is related to seal correlative technology field, the sealing strip in more particularly to a kind of field of sealing technology.
Background technology
Present Urban Underground walkway, cable passage etc. are laid with using prefabricated box culvert, and so construction can save
Duration is easily guaranteed that construction quality, reduces labour, while will not cause too much influence to urban transportation and civil plantation.
Since box culvert is generally embedded in underground, if sealing is bad, underground water is easy to infilter box culvert, destroys the environment in box culvert passage,
The especially underground pipe galleries waterproof such as electric power box culvert seems extremely important, in this case, for the sealing joint strip of building field
It comes into being.
At present, most of box culvert pipeline in Urban Buried Pipeline Network engineering is using putty type sealing strip either elasticity
Rubber weather strip, putty type sealing strip product do not have elastic material.There is product it is not easy to install and installation after poor sealing
The problem of；And elastic rubber sealing strip due to existing formula technique the problem of, after the use of certain time（After 10-15 not
Deng）, flexibility decrease, the problem of equally existing poor sealing.
Either putty type sealing strip or elastic rubber sealing strip, box culvert component surface is inherently relatively rough, in addition
Easy particle concentrations impurity on sealing surface, for sealing strip is enabled to reach preferable sealing effect, for mixed muds such as box culverts
Sealing strip on component, which plays good sealing function, needs the seal pressure of bigger.Then for using putty type at present
Sealing strip either elastic rubber sealing strip cannot reach one preferably than pressure value, therefore, design it is a kind of it is simple in structure,
Performance is stable, high sealing is than the sealing strip of pressure, is the technical issues of those skilled in the art institute is urgently to be resolved hurrily.
Utility model content
The utility model provides a kind of box culvert piping lane sealing strip that can improve seal pressure, which applies in box culvert
After piping lane sealing surface, seal pressure value can be significantly increased.
The utility model is realized by the following technical solutions：
A kind of box culvert piping lane sealing strip that can improve seal pressure, including elastic rubber weatherstrip body, further includes one
It is compounded in the first hydro-expansive rubber body of elastic rubber weatherstrip body upper surface and is integrally compounded in elastic rubber sealing strip
Second hydro-expansive rubber body of body lower face is provided on sealing surface along close where the first hydro-expansive rubber body
The semicircular notch that strip of paper used for sealing length direction opens up is provided on sealing surface along sealing where the second hydro-expansive rubber body
Several evenly arranged zigzag notches that length direction opens up.
Further, it is described by the first hydro-expansive rubber body, elastic rubber weatherstrip body, the second hydro-expansive rubber
The sealing sliver transvers section that bluk recombination forms is trapezoidal.
Further, offer on the lateral surface of the elastic rubber weatherstrip body and set along sealing strip length direction
Oval notch.
Further, the quantity of the semicircular notch is even number.
Further, the semicircular notch is in symmetric relation compared with the center line of elastic rubber weatherstrip body longitudinal direction.
Further, round hole, the round hole edge are further opened at the center of the elastic rubber weatherstrip body
The two ends that sealing strip length direction runs through sealing strip.
The beneficial effects of the utility model are：
1st, by adding elastic rubbery body, make the sealing strip that can be neatly embedded into according to the design feature of piping lane box culvert
It in the groove of piping lane, is easily installed, and due to the spring function feature of its own, after sealing strip installation, can effectively support outside
Hydro-expansive rubber body, enhance whole leakproofness；Hydro-expansive rubber body has water-swellable, absorb water repeatedly expands repeatedly
Automatic healing compensation sealing function, better guarantee is provided for the leakproofness of product.
2nd, semicircular notch and zigzag notch are provided on the top and bottom of elastic rubber weatherstrip body, it is above-mentioned
On the one hand notch can effectively reduce weatherstrip body face area, when the height dimension of weatherstrip body is close compared to for installing
When the sealing groove height of strip of paper used for sealing is bigger than normal, when applying certain compression to weatherstrip body, compared to traditional sealing strip, sheet
Sealing strip can obtain the flexible deformation of bigger, in this way, may be such that this sealing strip can be more smoothly mounted in seal groove；Into
One step, more than smaller face area be conducive on sealing surface obtain bigger seal pressure, may be such that this sealing strip have
There is more preferable or more reliable sealing effect；Further, when the impurity on sealing surface is close to notch, the table of weatherstrip body
Face more can readily generate enough deformations, influence the reliable of sealing to avoid the excessive gap of area is generated on sealing surface
Property；Meanwhile above-mentioned notch can also be used for positioning of the sealing strip in seal groove, particularly zigzag notch be convenient for it is other close
Sealing is to cooperation, so that sealing strip is installing the stability with position in the course of work.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further the utility model.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1, the utility model provides a kind of box culvert piping lane sealing strip that can improve seal pressure, including elasticity
