Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to an inner-hanging drainage device for the wind nozzle of a box girder. Background Technique

[0002] The steel box girder structure is a structural form widely used in bridge structures, usually composed of a top plate, a bottom plate, webs, diaphragms, longitudinal diaphragms, stiffeners, etc., which are connected by full welding. The existing drainage method of the box girder is as described in the patent number "CN111364364A". Before pouring the concrete of the box girder, steel bars, street lamp bases, pipes, and drainage pipe embedded parts are installed. The embedded drainage pipes are usually PVC drainage pipes or cast iron drainage pipes. By opening drainage holes on the surface of the box girder, the accumulated water on the surface of the box girder is introduced into the embedded drainage pipes through the drainage holes. Since the drainage pipes are embedded in the box girder during concrete pouring, once a certain part of the drainage pipe is damaged, its embedded layout in the box girder is very difficult to replace, and it is not easy to carry out later maintenance. Therefore, it needs to be solved urgently. Content of the Utility Model

[0003] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an inner-hanging drainage device for the wind nozzle of a box girder. The utility model can realize the external installation of the drainage pipe of the box girder, which is convenient for later maintenance.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] An inner-hanging drainage device for the wind nozzle of a box girder, including a box girder. The top of the box girder extends horizontally to both sides to form a box girder top plate for fixing the wind nozzle. Anti-collision guardrail bases are installed on both sides of the box girder along the length direction of the box girder. The upper edge of the wind nozzle is provided with a maintenance guardrail base parallel to the anti-collision guardrail base. The maintenance guardrail base, the anti-collision guardrail base and the box girder top plate enclose a U-shaped water collection channel. A drainage mechanism for draining water into the water collection channel is arranged on the anti-collision guardrail base; water inlets are opened on the surface of the box girder top plate, and a water trough corresponding to the position of the water inlets and used for draining water outward is installed at the bottom of the box girder top plate.

[0006] As a further scheme of the utility model: the water inlets are arranged at intervals on the box girder top plate along the direction parallel to the anti-collision guardrail base. The water trough is of a U-shaped trough plate structure with an open top. The water trough is arranged along the length direction of the water inlets, and each water inlet is located above the opening of the water trough.

[0007] As a further scheme of the utility model: a stainless steel inner lining is arranged on the inner wall of the water trough, and the top of the stainless steel inner lining is arranged in a closed-mouth shape, so as to correspond to the width of the water inlets.

[0008] As a further scheme of the utility model: the surface of the box girder top plate is arranged obliquely from top to bottom along the direction away from the anti-collision guardrail base.

[0009] As a further solution of the utility model: inspection guardrail bases and anti-collision guardrail bases are respectively arranged with inspection guardrails and anti-collision guardrails along the length direction of the box girder, and an inspection passage for personnel to pass through is formed between the inspection guardrail and the anti-collision guardrail.

[0010] As a further solution of the utility model: the bridge deck paving of the box girder is located between the two anti-collision guardrail bases, and the height of the bridge deck paving is higher than the plate surface height of the box girder top plate. The drainage mechanism is a water diversion pipe that penetrates the anti-collision guardrail base and is inclinedly arranged. One end of the water diversion pipe is flush with the bridge deck paving, and the other end of the water diversion pipe is flush with the box girder top plate.

[0011] As a further solution of the utility model: the air nozzle includes an air nozzle side plate that is inclinedly arranged at one end away from the box girder. An air nozzle partition plate with its plate surface arranged vertically connects and fixes the air nozzle side plate, the box girder top plate, and the box girder web. Reinforcing ribs are arranged along the length direction of the box girder on the plate surfaces of the air nozzle partition plate and the box girder web.

[0012] As a further solution of the utility model: water inlet gratings are installed on each water inlet.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model opens water inlets on the box girder top plate. The water on the box girder bridge deck is led to the area between the inspection guardrail base and the anti-collision guardrail base through the water diversion pipe of the anti-collision guardrail base, and is drained into the water tank through the water inlets. Its external drainage layout facilitates the later maintenance of the drainage system, and the drainage system has a long working life.

[0015] 2. The utility model designs the water tank as a U-shaped trough plate. After its top opening corresponds to each water inlet, it can directly receive the accumulated water flowing down from the water inlets. The water tank can be directly welded and fixed to the box girder top plate, and the space of the air nozzle structure is utilized to install the water tank to realize the external drainage of rainwater from the box girder; a stainless steel lining is installed on the inner wall of the water tank. While draining water through the stainless steel lining, the water tank itself is prevented from being corroded; after the accumulated water on the bridge deck is led to the box girder top plate through the inclined water diversion pipe, the inclined design of the box girder top plate can guide the accumulated water to the water inlets and quickly drain it outwards.

[0016] 3. The air nozzle side plate, air nozzle top plate, and box girder web of the utility model are welded and fixed to form the air nozzle structure of the box girder. The air nozzle partition plate can not only play a connecting role but also support the water tank from bottom to top, improving the stability of the drainage system during fixation.
