[0002] In order to quickly drain the water on the bridge surface and prevent rainwater from accumulating on the bridge deck and seeping into the beam body to affect the durability of the bridge, when designing the bridge, in addition to setting up longitudinal and transverse slope drainage on the bridge deck, a certain number of drainage pipes are needed to form a complete drainage system. The types of drainage pipes generally include metal drainage pipes, reinforced concrete drainage pipes, transverse drainage pipes, etc. The bridge deck drainage system should be set with longitudinal and transverse slopes and drainage holes on the bridge deck to reduce the water on the bridge surface and achieve the purpose of combining prevention and drainage.
[0003] A filter plate is usually installed at the entrance of the drainage pipe on the bridge. The filter plate is welded to the drainage pipe. The filter plate is usually just a simple circular cover. Foreign objects can easily clog the filter plate on the bridge deck, resulting in low drainage efficiency of the bridge deck and water accumulation on the bridge deck, which affects driving safety. Moreover, foreign objects can easily get entangled on the filter plate, which is troublesome to clean. Therefore, we designed a bridge deck drainage system that uses a tetrahedron to replace the filter plate. It is difficult for foreign objects to cover and clog it completely, so that the accumulated water can enter the drainage pipe from multiple sides, thereby improving drainage efficiency. Moreover, after foreign objects get entangled, the tetrahedron can be removed to facilitate the cleaning of the entangled objects. Utility Model Content

[0028] Embodiment 2:
[0029] Figure 1-4A bridge deck drainage system according to an embodiment of the utility model is shown, wherein a drainage pipe 1 is pre-buried on the bridge, a plurality of reinforcing rods 14 are welded to the bottom of the drainage pipe 1, a concrete layer 15 is arranged on the bridge deck, the drainage pipe 1 is fixed on the bridge deck through the concrete layer 15, the reinforcing rods 14 are pre-buried in the concrete layer 15, a slope which is level with the bottom of the inner cavity of the drainage pipe 1 is arranged above the concrete layer 15, the outer end of the drainage pipe 1 extends to the outside of the bridge, the inner end of the drainage pipe 1 is flush with the bridge fence, the connection between the drainage pipe 1 and the bridge can be reinforced by the arrangement of the reinforcing rods 14, and the drainage pipe 1 is prevented from slipping off the bridge deck, and a conical filter 2 is arranged at the right end of the drainage pipe 1, the conical filter 2 is provided at the bottom of the inner cavity of the drainage pipe 1, and the conical filter 2 is provided at the bottom of the inner cavity of the drainage pipe 1. A plurality of strip-shaped drain outlets 3 are provided on the three surfaces of the conical filter element 2, a strip-shaped mounting plate 4 is welded on the top of the conical filter element 2, a movable strip-shaped extrusion plate 5 is arranged on the left side of the strip-shaped mounting plate 4, a movable groove 11 is provided on the left side of the strip-shaped mounting plate 4, a rotating shaft rod 12 is fixedly connected to the inner cavity of the movable groove 11, the strip-shaped extrusion plate 5 is rotatably connected to the surface of the rotating shaft rod 12, an extrusion groove 6 matched with the strip-shaped extrusion plate 5 is provided on the top of the right end of the drain pipe 1, two symmetrical threaded holes 9 are provided on the strip-shaped mounting plate 4, the inner cavity of the threaded hole 9 is threadedly connected with a hexagonal screw 7, one end of the hexagonal screw 7 is fixedly connected with a frustum rod 8, and the strip-shaped extrusion plate 5 is placed on the top of the frustum rod 8.
[0030] Working principle: When the utility model is used, the user picks up the conical filter 2, and inserts the strip extrusion plate 5 on the left side of the strip mounting plate 4 into the inner cavity of the extrusion groove 6. During this period, the positioning plate 13 is inserted into the inner cavity of the drain pipe 1 to guide the conical filter 2. After the conical filter 2 contacts the drain pipe 1, the hexagonal screw 7 is inserted into the inner cavity of the threaded hole 9 and the threaded hole 9 is screwed. The female thread relationship makes the hexagonal screw 7 and the cone rod 8 rotate and move toward the inner cavity of the extrusion groove 6. The thick end of the cone rod 8 contacts the strip extrusion plate 5 so that the strip extrusion plate 5 is axially connected with the rotating shaft rod 12. The strip-shaped extrusion plate 5 is rotated upward to squeeze the inner wall of the extrusion groove 6, so that the conical filter element 2 is fixedly installed.

It is difficult for foreign objects to cover and block it completely, so that the accumulated water can enter the drain pipe from multiple sides, thereby improving the drainage efficiency. Moreover, after the foreign objects are entangled, the quadrangular pyramid can be removed, so it is convenient to clean up the entangled objects.
[0031] In summary, the bridge deck drainage system, by picking up the conical filter 2, inserting the strip extrusion plate 5 on the strip mounting plate 4 into the inner cavity of the extrusion groove 6, at this time, the conical filter 2 is attached to the end of the drain pipe 1, and then the hexagonal screw 7 is picked up and inserted into the inner cavity of the threaded hole 9, and then the hexagonal screw 7 is screwed, so that the cone rod 8 and the hexagonal screw 7 rotate and move deep into the inner cavity of the extrusion groove 6, and the cone rod 8 and the hexagonal screw 7 drive the strip extrusion plate 5 to rotate upward, so that the strip extrusion plate 5 is squeezed on the inner wall of the extrusion groove 6, so as to fix the conical filter 2, and the conical filter 2 can be achieved. By using a tetrahedron instead of a filter plate, it is difficult for foreign objects to completely cover and block it, so that accumulated water can enter the drain pipe from multiple sides, thereby improving drainage efficiency. Moreover, once foreign objects are entangled, the tetrahedron can be removed, making it convenient to clean the entangled objects. This solves the problem that a filter plate is generally provided at the inlet of the drain pipe on the bridge. The filter plate is welded to the drain pipe. The filter plate is generally just a simple circular cover plate. Foreign objects can easily block the filter plate on the bridge deck, resulting in low water drainage efficiency on the bridge deck, water accumulation on the bridge deck, affecting driving safety, and foreign objects can easily entangle on the filter plate, making cleaning more troublesome.
