Abstract

The utility model discloses a J-shaped bridge drainage device, which is arranged on a steel bridge (3) and comprises a J-shaped drainage groove (1), a clapboard (2) and a water collection pipe (4); the drainage channel (1) is symmetrically arranged along the outer edges of two sides of the steel bridge (3), the partition plates (2) are longitudinally arranged along the steel bridge (3) at intervals, the partition plates (2) are welded at the lower end of the drainage channel (1), and the drainage channel (1), the partition plates (2) and the steel bridge (3) are welded into a whole; it has overcome prior art and has difficult to ensure that the bridge floor ponding is whole to be collected to and to the great shortcoming of the mediation of drainage management and the work degree of difficulty of decontaminating, has overall structure simply, and construction convenience compares traditional centralized drainage device, reduces engineering cost, the obvious advantage that improves of its economic benefits.

Description

J-shaped bridge drainage device

Technical Field

The utility model relates to water source protection area or tourist attraction steel construction bridge drainage facility technical field specifically are a bridge drainage device of J shape.

Background

As shown in fig. 1-2: the drainage structure of the existing steel bridge is schematically shown, the drainage structure comprises a water drain pipe 6, a water collecting pipe 4, pipe clamps 7, a filter screen and the like, the water drain pipe 6 is arranged along the longitudinal direction of the steel bridge 4 at certain intervals, and the water collecting pipe 4 is arranged along the longitudinal direction of the steel bridge 3. High both sides are low in the middle of the bridge floor, and rainwater flows to the lower position in both sides along the bridge floor, collects bridge floor ponding through bridge floor wash-off pipe 6, is discharged the bridge floor ponding to municipal pipe network by collector pipe 4.

Usually, the sidewalk or the crash barrier 5 prevents the accumulated water on the bridge floor from overflowing, and plays a role in retaining water. However, this drainage arrangement makes it difficult to ensure that the deck ponding is collected and drained outside the protected area.

For the steel bridge crossing a water source protection area or a tourist attraction, because the requirement on environmental protection is higher, accumulated water on the bridge deck needs to be completely discharged to the outside of the protection area, and each drop of sewage is ensured not to flow into the protection area. To the drainage design of this type of bridge, obviously traditional concentrated drainage setting is difficult to satisfy the requirement completely, and the bridge floor ponding overflows under the special circumstances need be avoided addding higher breakwater on the one hand, and on the other hand needs to establish steel members such as similar railing as far as possible in the outlet conduit inboard to the mediation and the work of decontaminating to drainage management degree of difficulty is great.

Therefore, a drainage device is urgently needed to solve the above problems.

Disclosure of Invention

The utility model relates to an overcome the weak point of above-mentioned background art, and provide a bridge drainage device of J-shaped.

The utility model aims at being implemented through the following technical scheme: a J-shaped bridge drainage device is arranged on a steel bridge and comprises a J-shaped drainage groove, a partition plate and a water collection pipe; the edge the both sides outer fringe symmetry of steel bridge be provided with water drainage tank, follow steel bridge longitudinal separation arrange the baffle, the baffle welding at water drainage tank's lower extreme, water drainage tank, baffle and steel bridge between weld mutually even as an organic whole.

In the above technical scheme: one end of the drainage groove is welded with the steel bridge, and the other end of the drainage groove extends out of the outer edge of the steel bridge and the top of the drainage groove is higher than the horizontal plane of the steel bridge.

In the above technical scheme: the both ends of water drainage tank all be provided with the collector pipe and link up each other.

The utility model has the advantages of as follows: 1. the utility model provides a water drainage tank symmetry sets up at the horizontal outermost edge of steel bridge, and water drainage tank height is interior low outward, and uncovered arranging can be fast with the discharge of the whole ponding collection of bridge floor, ensures that each drip of bridge floor does not flow into the protection zone, and the at utmost satisfies the environmental protection requirement.

2. The utility model provides a water drainage tank is uncovered arranging, conveniently seeks the problem when overhauing, conveniently cleans and dredge when decontaminating.

3. The utility model provides a water drainage tank can confirm outside baffle height according to bridge floor ponding flow, especially to the pipeline bridge under the booster condition, can avoid booster liquid excessive.

4. The utility model provides a water drainage tank simple structure, construction convenience compares traditional centralized drainage device, reduces engineering cost, and its economic benefits obviously improves.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to FIGS. 3-4: a J-shaped bridge drainage device is arranged on a steel bridge 3 and comprises a J-shaped drainage channel 1, a partition plate 2 and a water collection pipe 4; edge the both sides outer fringe symmetry of steel bridge 3 be provided with water drainage tank 1, follow 3 longitudinal separation of steel bridge arrange baffle 2, baffle 2 welding be in water drainage tank 1's lower extreme, water drainage tank 1, baffle 2 and steel bridge 3 between weld mutually even as an organic whole. One end of the drainage channel 1 is welded with the steel bridge 3, the other end of the drainage channel extends out of the outer edge of the steel bridge 3, and the height of the top of the drainage channel is higher than the horizontal plane of the steel bridge 3; the both ends of water drainage tank 1 all be provided with collector pipe 4 and through connection each other.

The utility model discloses a following specific work process: be "J shape" water drainage tank 1 along 3 bilateral symmetries of steel bridge set up in outer fringe, low in the water drainage tank outer height, uncovered arranging, bridge floor sewage flows into water drainage tank fast, sets up baffle 2 and water drainage tank welding in order to support water drainage tank along 3 vertical every certain distance of steel bridge. The J-shaped drainage channel 1 is connected with a water collecting pipe at the bridge head of two banks of the steel bridge 3 to discharge sewage outside the protection area. The height of the outer baffle of the J-shaped drainage channel (1 in figure 1) can be determined according to the drainage flow of the bridge deck.
