Background
The drainage of the existing bridge expansion joint device has the following three modes: 1. direct drainage, rainwater and lime soil on the bridge are directly drained from the bridge without any measures, and adverse effects are caused on the bridge structure and the environment. 2. The waterstop is a V-shaped structure, two sides of the waterstop are embedded in the special-shaped steel mounting grooves respectively, two sides of the waterstop are supported by the special-shaped steel to tilt upwards, and rainwater and lime soil on the bridge are stored in the waterstop for a long time to cause adverse effects on the bridge structure and the bridge expansion device. 3. In part of urban projects with higher water stopping and draining requirements, the retaining walls on two sides of the bridge are supported by special-shaped steel to be tilted upwards, holes are dug from the bottom of the water stop belt, and the holes are connected and drained by PVC civil water guide pipes.
The drainage effect of the three water stopping and drainage devices is not thorough, a small amount of water accumulation can be caused, and the accumulation of the dust is serious. For the scheme that the two sides of the water stop are upwards tilted through the special-shaped steel supports, after long-term use, the water stop and the water guide are easy to damage, and the sealing performance is reduced. In addition, because the bridge has the elasticity, when high temperature, the crack is very little between the bridge, and waterstop end structure is fragile, and debris such as stone, dust can fall into lower floor's bridge, cause the potential safety hazard to bridge lower floor's driving, and can influence bridge life. In summary, there is a need for further improvement of the water stopping and guiding device of the conventional bridge expansion joint device.

In order to solve the problem that the water guide end is difficult to connect with stainless steel in construction, the upper water stop belt is an upper canvas water stop belt, the lower water stop belt comprises a lower stainless steel water stop belt and a lower canvas water stop belt which are mutually connected, and the lower water guide end is arranged on the lower canvas water stop belt.
The water stop belt can be in various forms, and preferably, the cross sections of the upper water stop belt and the lower water stop belt are U-shaped.
Preferably, in any one of the above schemes, the upper part of the upper water stop band is fixed on an upper water stop band hanging plate which is fixed on a bridge body in advance, the inner side of the upper part of the lower water stop band is provided with a pressing plate, and the lower water stop band is riveted on a bottom plate which is fixed on the bridge body in advance through the pressing plate and an anchoring screw.
Compared with the prior art, the utility model has the advantages of: this stagnant water of bridge expansion joint device, water guide device adopt two-layer waterstop structure from top to bottom, and under the condition that the damage appears in upper waterstop, the silt and the water of seepage can be inserted the bridge drainage system by lower floor's waterstop to avoid causing the potential safety hazard to the lower floor driving, reduce the influence to the bridge life-span. And the upper water guide pipe of the upper water stopping end is inserted into the lower water guide pipe of the lower water stopping end, so that smooth drainage between the upper water guide pipe and the lower water guide pipe can be ensured.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the water stopping and guiding device for a bridge expansion joint device of the present embodiment includes a water stopping strip and a water guiding tip installed at an end of the water stopping strip. Wherein, the waterstop is bilayer structure, including ending water tape 1 and lower waterstop 2, goes up water tape 1 and lower waterstop 2 and all is the strip, and the cross section all is the U type. Correspondingly, the water guide end comprises an upper water guide end 3 and a lower water guide end 4, wherein the upper water guide end 3 is installed at the end part of the upper water stop belt 1, the bottom of the upper water guide end 3 is provided with an upper water discharge port 31, and the upper end of the upper water guide pipe 5 is installed on the upper water discharge port 31; the lower water guide end 4 is installed at the end part of the lower water stop 2, the lower water guide end 4 is positioned under the upper water guide end 3, the bottom of the lower water guide end 4 is provided with a lower water outlet 41, the upper end of the lower water guide pipe 6 is installed on the lower water outlet 41, and the lower end of the upper water guide pipe 5 extends into the lower water guide pipe 6.
The upper water guide end 3 is arranged on the outer side of the upper water stop belt 1, an upper water guide pressing plate 7 is arranged at the corresponding position on the inner side of the upper water stop belt 1, and the upper water guide end 3 and the upper water guide pressing plate 7 are fixedly connected through a screw 9. The lower water guide end 4 is arranged on the outer side of the lower water stop belt 2, a lower water guide pressing plate 8 is arranged at the corresponding position on the inner side of the lower water stop belt 2, and the lower water guide end 4 and the lower water guide pressing plate 8 are fixedly connected through a screw 9. Therefore, the water stop belt is completely and tightly attached to the corresponding water stop end, the sealing protection effect is achieved, and the sealing performance and the reliability of the device are improved.
In addition, the upper stop water band 1 of the present embodiment is an upper canvas water stop band, and the lower water stop band 2 includes a lower stainless steel water stop band 21 and a lower canvas water stop band 22 which are connected to each other. Thus, the upper water guide end 3 is installed on the upper canvas waterstop, and the lower water guide end 4 is installed on the lower canvas waterstop 22, so that the problem that the water guide end is difficult to connect with stainless steel during construction can be solved. And the main structure of the lower water stop adopts a stainless steel plate to be molded, so that the structure is firm, the cost is low, and the service life is long.
The water stopping and guiding device of the embodiment provides a mounting structure at one end of the water stopping belt, the other end of the water stopping belt is provided with the water stopping end heads, the water stopping end heads play a role in stopping water, the water stopping end heads can adopt a conventional structure, and description is omitted here. In addition, the other end of the water stop belt can also adopt the same water guide end.
As shown in fig. 3, the mounting structure of the water stopping and guiding device is as follows: the upper part of the upper stop water hose 1 is fixed on an upper stop water hose hanging plate 101 which is fixed on a bridge beam body 100 in advance through an anchoring screw 103 to form an upper water stop structure, and the upper water stop structure is positioned below a seam crossing plate 105 of the expansion joint device; the lower water stop 2 is provided with a pressing plate 102 on the inner side of the upper part thereof, and the lower water stop 2 is riveted on a bottom plate 104 which is fixed on the bridge beam body 100 in advance through the pressing plate 102 and an anchor screw 103 to form a lower water stop structure.
This stagnant water, water guide device adopt double-deck waterstop structure back, in case damage appears as last waterstop 1, the silt and the water of seepage can be by lower waterstop 2 access bridge drainage system, debris such as stone, dust can not fall into lower floor's bridge to avoid causing the potential safety hazard to lower floor's driving, reduce the influence to the bridge life-span.
In addition, because smooth and smooth installation between the waterstop of this embodiment and the stagnant water end does not have the installation closed angle, waterstop long service life, stagnant water, water guide structure still have the plastic deformation characteristic, and when the crack is very little between the bridge under the high temperature weather, the structure can not damage, still can keep good drainage and leakproofness. And, stagnant water, the water guide device of this embodiment can be applicable to the bridge expansion joint device of multiple specification, and the commonality is good, can promote on a large scale.
