Abstract
The utility model discloses a city utility tunnel compound seal strip, this sealing strip is described by the elastic rubber body and the bluk recombination of chance water inflation rubber in echelon, wherein, meets water inflation rubber position and inclines in trapezoidal base, and the setting is personally experienced sth. Part of the body at the offside of meeting the water inflation rubber body to the elastic rubber, the utility model discloses an add the elastic rubber body, make this sealing strip can be according to the structural feature of piping lane box culvert, be embedded into the slot of piping lane in a flexible way, the installation of being convenient for, again because its self elasticity functional characteristics, the outside chance water inflation rubber body can effectively be supported to sealing strip installation back, strengthens holistic leakproofness, meeting the water inflation rubber body and having the water of chance inflation, the sealed function of the automatic healing compensation of inflation that absorbs water repeatedly, its life through the two compound back, when guaranteeing good sealing performance, lengthens whole life than the extension greatly of the elastic rubber body greatly simultaneously, reaches the technical requirement of the century -old use of underground pipe gallery engineering.
Description
Technical field
The utility model relates to a kind of rubber weather strip, particularly relates to a kind of compound sealing strip for Urban Underground piping lane.
Background technology
At present, what the box culvert pipeline great majority in Urban Buried Pipeline Network engineering adopted is putty type weather strip or elastic caoutchouc weather strip, in known technology, what the box culvert pipeline great majority adopted in urban pipe network engineering adopted is exactly the sealing of this putty type, and putty type weather strip product does not have elastic material.There is the problem that this product is not easily installed and installed rear poor sealing; And elastic caoutchouc weather strip is due to the problem of existing formula technique, after the use of certain hour (as 5 years, 10 years etc.), flexibility decrease, also exists the problem of poor sealing equally.
As shown in Figure 1, Fig. 1 product is the putty type weather strip shape that present industry uses, during use, putty weather strip is embedded in the groove of box culvert pipeline, product self does not have elasticity and solid shape, so can cause install time product due to be putty-like state be not easy embed pipeline design sealed groove in, or the shape of not fixing due to self after installing can come off, and affects installation rate.Simultaneously, because whole material is all putty type, after in the sealed groove of the design of product embedding pipeline, the shape that putty weather strip is not fixed due to self and elasticity are as support, time has been grown and may come off and in sealed groove internal strain, cause the poor sealing of product; Elastic caoutchouc weather strip can make up the deficiency of putty type weather strip to a certain extent, but shortcoming is that application life is shorter.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, uses century-old technical requirements to reach Urban Underground pipe gallery, and propose one and be easy to install, good sealing effect, reaches century-old compound sealing strip application life.
The utility model is achieved through the following technical solutions: Urban Underground pipe gallery compound sealing strip, and sealing bar is formed by elastic rubbery body and hydro-expansive rubber bluk recombination.
Further, the design of sealing bar interface shape is in trapezoidal.
Further, the hydro-expansive rubber body in sealing bar is positioned at trapezoidal bottom avris, and elastic rubbery body is arranged on the offside of hydro-expansive rubber body.
Further, hydro-expansive rubber body is also provided with an arc gap, the installation that this breach is designed to product provides reliable guarantee.
Owing to have employed said structure, the utility model compared with prior art, there is following beneficial effect: by setting up elastic rubbery body, sealing bar according to the design feature of piping lane box culvert, can be embedded in the groove of piping lane neatly, be convenient to install, again due to the spring function feature of himself, after weather strip is installed, can the hydro-expansive rubber body of effective supports outer, strengthen the sealing of entirety; Hydro-expansive rubber body has water-swellable, repeatedly to absorb water the automatically healing compensation sealing function that repeatedly expands, and the sealing for product provides better guarantee.Its application life, comparatively elastic rubbery body extended greatly simultaneously, after the two compound, while guaranteeing excellent sealing performance, greatly extended whole service life, improve the reliability of installation, reached the technical requirements that underground pipe gallery engineering a century uses.
Accompanying drawing explanation
Fig. 1 is putty type sealing joint strip schematic cross-section in prior art;
Fig. 2 is the utility model schematic cross-section.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1:
As shown in Figure 2, Urban Underground pipe gallery compound sealing strip in the present embodiment is composited by elastic rubbery body 1 and hydro-expansive rubber body 2, wherein, the global design of sealing bar is trapezoidal, hydro-expansive rubber body 2 is positioned at trapezoidal bottom avris, elastic rubbery body 1 is arranged on the offside of hydro-expansive rubber body 2, namely trapezoidal top margin side.For ease of installing, hydro-expansive rubber body 2 is also provided with arc gap 3.
When this weather strip uses, what first make dimension according to the size of underground pipe gallery meets weather strip, the Cross section Design trapezoidal shape of weather strip is beneficial to installation, section area 20-40%mm larger than piping lane pipeline groove area, object is the inherent difficult drop-off of groove utilizing the spring function of elastic rubbery body 1 and be tightly supported on box culvert pipe.The hydro-expansive rubber body 2 of elastic rubbery body 1 offside is placed in the sealing position that piping lane is coupled to each other, after hydro-expansive rubber body 2 meets water, automatically repeatedly can absorb water and repeatedly expand, there is healing compensation sealing function automatically, effectively increase sealing and the application life of product.Meanwhile, owing to being provided with elastic rubbery body 1, product possesses certain resilient shapes when mounted, effectively can solve the problem come off after product is not easily installed and installed, accelerate the installation rate of product, improve process operability, add the operation strategies of this product.
Certainly, in other embodiments, can be different according to the use occasion of piping lane, exchange the position of elastic rubbery body 1 and hydro-expansive rubber body 2.
