[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment: A bridge drainage device for bridge engineering, such as Figure 1As shown, it includes a bridge deck 1 and a supporting structure 2 fixedly connected thereto. The bridge deck 1 is formed in one piece by pouring concrete on a plurality of arranged steel bars. The concrete has good plasticity and can be formed into various building components through design and formwork. The high strength of concrete and steel bars enables the manufactured bridge deck 1 to withstand greater forces. At the same time, the bridge deck 1 made of concrete is relatively rough, which can provide a certain friction for pedestrians and vehicles when passing, avoiding slipping during passing, thereby ensuring the safety and service life of the bridge deck 1. The load of the bridge deck 1 can be effectively transmitted and dispersed through the supporting structure 2, which helps to maintain the overall structural safety of the bridge and prevent damage to the bridge due to overload or environmental factors.

[0022] like Figure 1-Figure 2 As shown, the support structure 2 includes a plurality of top rods 3 fixedly connected to each other, a plurality of inclined support rods 4 and a plurality of bottom rods 5, the top rods 3, the support rods 4 and the bottom rods 5 are all made of 7075 aluminum alloy material, and the 7075 aluminum alloy material has a very high strength level, so that the manufactured support structure 2 can withstand a large external force without being easily deformed, and the 7075 aluminum alloy material also has good corrosion resistance, so that the manufactured support structure 2 is not easily eroded by rainwater and rusted, and the stability of the support structure 2 can be maintained for a long time, and the bridge deck 1 is provided with a plurality of long strip-shaped drainage grooves 6 and a plurality of rectangular drainage grooves 7 along its length direction, and the plurality of drainage grooves 7 are all located at both ends of the bridge deck 1 in the length direction, and the bottom surface of the bridge deck 1 and the top surfaces of the plurality of support rods 4 are fixedly connected to each other by a plurality of fasteners 13, and the fasteners 13 used to fix the bridge deck 1 and the support rods 4 are all located between adjacently arranged steel bars to avoid the fasteners 13 from damaging the steel bars during connection.

[0023] like Figure 1-Figure 2 As shown, the width of the bridge deck 1 is the same as the distance between the two side end faces of adjacent support rods 4 that are away from each other. The main support rod 4 passes through the drain groove 7 and is fixedly connected to the top surface of the bottom rod 5 by the argon arc welding method. The side of the top rod 3 close to the bridge deck 1 is fixedly connected to the ends of several support rods 4 away from the bridge deck 1 by the argon arc welding method. The connection between the bottom rod 5, the support rod 4 and the top rod 3 can be sealed by the argon arc welding method to prevent moisture and dust from entering the connection and affecting the connection effect.

[0024] like Figure 1-Figure 2As shown, a plurality of support rods 4 are provided with an arc-shaped guide groove 18 along the length direction thereof and on the side away from the bridge deck 1, and the end of the guide groove 18 away from the top rod 3 is interconnected with the drain groove 27, and the side of the top rod 3 away from the bridge deck 1 is provided with an arc-shaped guide groove 29, and a through hole 10 is provided at the connection between the top rod 3 and the support rod 4, so that the end of the guide groove 29 away from the bottom rod 5 can be interconnected with the guide groove 18 through the through hole 10. The length of the drain groove 27 is greater than the width of the bottom rod 5, and the water on the support structure 2 can be discharged separately through the interconnected guide groove 18, guide groove 29 and drain groove 27, so as to prevent the water on the support structure 2 from flowing into the bridge deck 1, thereby reducing the drainage burden of the bridge deck 1.

[0025] like Figure 1-Figure 5 As shown, two sidewalks 11 are provided on the side of the bridge deck 1 close to the top rod 3. The sidewalk 11 is integrally formed by pouring concrete on a plurality of arranged steel bars. When the bridge deck 1 is formed, two rectangular protrusions 15 are reserved on the side close to the top rod 3. When the sidewalk 11 is formed, an integral rectangular recess 16 is reserved on the bottom surface. The cross-sectional size of the recess 16 is the same as that of the protrusion 15. The two sidewalks 11 are clamped on the bridge deck 1 through the recess 16 and the protrusion 15. The end surfaces of several sidewalks 11 that are away from each other are fixedly connected with the end surfaces of several support rods 4 that are close to each other on both sides of the length direction of the bridge deck 1 through several fasteners 13. The sidewalk 11 is located above the drain groove 2 7. The bottom surface width of the sidewalk 11 is greater than the length of the drain groove 2 7 away from the support rod 4. The sidewalk 11 can be used for pedestrians to pass through and is also used to cover the drain groove 2 7 to prevent objects from falling out of the bridge from the drain groove 2 7.

[0026] like Figure 1-Figure 4 As shown, several reinforcements 12 are symmetrically arranged along the length direction of the drain grooves 6. The reinforcements 12 are made of 7075 aluminum alloy and have high strength and resistance to deformation. The several reinforcements 12 are fixedly connected to the inner wall of the drain grooves 6 by several fasteners 13. The fasteners 13 are bolts made of stainless steel. The top surfaces of the several reinforcements 12 are flush with the top surface of the bridge deck 1. The support of the several reinforcements 12 reduces the deformation and damage of the drain grooves 6 caused by long-term vehicle rolling. Several adjacent reinforcements 12 and the inner wall of the drain grooves 6 are surrounded by several rectangular drainage outlets 14. The surfaces of the two sidewalks 11 for pedestrians to pass are slightly inclined downward in the direction of approaching each other. Without affecting the passage of pedestrians, the moisture on the sidewalks 11 can be gathered on the bridge deck 1, and the moisture on the bridge deck 1 can be quickly discharged through the several drainage outlets 14 to avoid the formation of water accumulation on the bridge deck 1 and affecting the passage.

[0027] Working principle: The water on the supporting structure 2 is discharged from the bridge separately through the interconnected guide groove 1 8, guide groove 2 9 and drain groove 2 7, thereby reducing the drainage burden of the bridge deck 1. The large number of drainage outlets on the bridge deck 1 can quickly discharge the gathered water from the bridge, thereby ensuring the normal passage of vehicles and pedestrians. The several reinforcements 12 in the drain groove 6 reduce the damage to the drainage outlet 14 caused by vehicle rolling, ensuring the effective drainage performance of the drainage outlet 14.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
