Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck pavement drainage, in particular to a flexible drainage unit and a flexible drainage system. Background Technique

[0002] The viaduct is a bridge that spans roads in urban construction. The multi-layer three-dimensional structure ensures the smooth flow of urban traffic. However, there are currently many problems with the bridge deck drainage system, which have an impact on traffic and safety.

[0003] First of all, the drainage holes on the bridge deck are mostly arranged intermittently, and the accumulated water cannot be quickly discharged. At the same time, the drainage holes are relatively small and are easily blocked by sundries. When the instantaneous rainfall is too large, rainwater is likely to accumulate on the road surface. The tires of vehicles traveling at high speeds are affected by the accumulated water and are prone to skidding and losing control. The splashed water will affect the passage of vehicles and pedestrians in the lower layer.

[0004] In addition, the paving process of the road surface cannot effectively ensure that the drainage holes are at a lower position, resulting in water accumulation and puddles in some sections.

[0005] Moreover, the interlayer water cannot be discharged. The existing drainage system can only drain the road surface, but the water that seeps into the asphalt concrete paving layer cannot be treated, resulting in water backflow problems at the expansion joints or wet joints.

[0006] The accumulated water on the bridge deck will corrode the expansion joints, reduce the concrete strength, and shorten the service life of the bridge. The accumulated water seeps from the bridge to under the bridge and spreads along the bridge deck. When it flows to the abutment cap, it is easy to cause corrosion of the bearings and affect the bearing performance. At the same time, due to the dark space under the bridge, the wall surface will have water stains for a long time after water seepage, breed moss, turn black in color, affect the durability of the concrete structure, the beauty of the bridge deck, and the performance of other components.

[0007] The existing drainage system cannot effectively solve the above problems. Therefore, it is necessary to design a new drainage system that can improve the existing problems of road surface water accumulation and interlayer water backflow. Content of the Utility Model

[0040] Next, with reference to the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] The object of the present utility model is to provide a flexible drainage unit and a flexible drainage system to solve the problems existing in the above-mentioned prior art, which is conducive to the drainage of road surface water and interlayer water, and improves the existing problems of road surface water accumulation and interlayer water backflow.

[0042] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] As Figures 1 to 9 shown, the present utility model provides a flexible drainage unit, including a portal drainage plate. Inside the portal drainage plate 1, longitudinal support ribs 2 and transverse support ribs 3 are arranged at a certain interval. The longitudinal support ribs 2 are arranged along the extending direction of the portal drainage plate 1 and are provided on the top surface 1-1 and two side surfaces 1-2 of the portal drainage plate 1. The transverse support ribs 3 are also of portal structure and are arranged inside the portal drainage plate 1. The longitudinal support ribs 2 and the transverse support ribs 3 are connected to form a framework. The connection between the longitudinal support ribs 2, the transverse support ribs 3 and the portal drainage plate 1 can adopt connection methods such as welding, plugging, bolts, etc. Drainage holes are arranged in an array on the top surface 1-1 and the side surface 1-2 of the portal drainage plate 1. The drainage holes include top surface drainage holes 1-3 and side surface drainage holes 1-4. Both the top surface drainage holes 1-3 and the side surface drainage holes 1-4 adopt a flanging process to increase the stiffness of the drainage hole positions.

[0044] As Figure 5 and Figure 15 shown, in order to achieve a better drainage effect, the side surface drainage holes 1-4 of the portal drainage plate 1 adopt a folding flanging, that is, three sides are connected, and the remaining side is open and folded parallel to the back of the opening, and is arranged perpendicular to the axis of the opening, which can prevent debris from entering. The top surface drainage holes 1-3 of the portal drainage plate 1 can adopt the same folding flanging as the side surface drainage holes 1-4, or can adopt an inner hole flanging different from the structure of the side surface drainage holes 1-4. As Figure 6 shown, during inner hole flanging, the hole position material is bent inward to form a support perpendicular to the hole surface.

[0045] In one of the embodiments, by arranging a plurality of flexible drainage units on the bridge surface in sequence and then connecting the head and the tail, a complete flexible drainage system can be formed. As Figures 10 to 14As shown, each unit is connected end to end. When the hook connection form of the U-shaped drainage board 1 is adopted, as shown in the figure, two adjacent flexible drainage units are respectively named the first unit and the second unit. The tail end A of the first unit is connected to the head end B of the second unit. The connection method is the hook connection. The hook connection means that there are hook-shaped parts similar to the buckle structure at the A end of the first unit and the B end of the second unit, and the two hook-shaped parts are hooked together to form a whole. When the convex hole connection method of the U-shaped drainage board 1 is adopted, a spherical structure protruding inward or outward is provided at the A end of the first unit, and a round hole or an oblong hole of corresponding size is provided at the B end of the second unit. The protruding spherical structure is inserted into the round hole under the action of an external force, and the protruding structure is stuck to form a whole. When the rivet connection of the U-shaped drainage board 1 is adopted, corresponding holes are provided at the A end of the first unit and the B end of the second unit, and the rivet is passed through the two holes and then fixedly connected. Similarly, the bolt connection method is the same, and the welding is directly positioned and welded into one body. Other connection methods can also be adopted, which will not be elaborated here.

[0046] For the unit structure with requirements for the turning radius, when connecting, each connection method needs to leave a corner displacement space. For example, there is a moving space on both sides of the hook connection, the B end of the second unit in the convex hole connection is an oblong hole, and the convex spherical structure can move in the oblong hole. One end of the rivet connection is a petal-shaped hole formed by superimposing two oblong holes, and the rivet can move in the petal-shaped hole after being fixed. The same applies to other situations.

[0047] In another embodiment, each unit is connected end to end. When the longitudinal support rib plate 2 is used for connection, the A end of the first unit adopts a longitudinal support rib plate 2 in the shape of a square tube, and a connection groove is opened at its end. A round hole is opened on the side wall of the connection groove. The end of the longitudinal support rib plate 2 at the B end of the second unit is provided with a connecting rod, and a spherical protrusion is provided at the end of the connecting rod. After the connecting rod at the B end of the longitudinal support rib plate 2 of the second unit is inserted into the connection groove of the longitudinal support rib plate 2 at the A end, the spherical protrusion protrudes from the round hole, and the two units are connected into one body. An opening groove can also be provided at the A end of the first unit, and the diameter of the groove opening is smaller than the inner diameter. The connecting rod at the B end of the second unit has a structure with a large outer diameter at the end and a small outer diameter at the root. After the connecting rod at the B end is forced to be inserted into the opening groove at the A end, the protrusion at the B end of the connecting rod enters the opening groove, and the two units are connected into one body. Other plug-and-lock connections, rivet connections, bolt connections, welding and other connection methods for the longitudinal support rib plate 2 will not be elaborated here.

[0048] For the unit structure with requirements for the turning radius, when connecting, each connection method needs to leave a corner displacement space. For example, the round hole at the A end is set as an oblong hole, and the opening groove is set as a long opening groove, so that the protrusion at the B end can move at the A end. The same applies to other situations.

[0049] On the above basis, in one of the embodiments, the present invention provides a method for combining a flexible drainage system, including the following steps:

[0050] Step 1: A plurality of longitudinal support ribs 2 and transverse support ribs 3 are arranged inside the portal drainage board 1 at a set spacing to form a flexible drainage unit.

[0051] Step 2: A plurality of flexible drainage units are arranged along the entire road surface. The adjacent two flexible drainage units are connected by the portal drainage board 1 or the longitudinal support rib 2, and the connection can achieve a fold angle within a preset angle range to achieve different bending radii and meet the requirements of the road surface turning radius.

[0052] The length of each unit and the turning radius ability are designed according to the actual situation and will not be described in detail here.
