Abstract

This utility model relates to the field of drainage structure technology, and in particular to a temporary drainage structure for road reconstruction. A connecting groove is formed on one side of the trench, and an overlapping edge is fixedly connected to the other side of the connecting groove. A first groove is formed at the upper end of the overlapping edge, and a sealing gasket is connected within the first groove. A hollow rubber ring is fixedly connected to the bottom end of the sealing gasket. Several second grooves are formed on one side of the overlapping edge, and each second groove contains a sphere. A connecting rod is fixedly connected to one side of each sphere, and one end of each connecting rod extends into the first groove. A fixing member is connected to the upper end of the trench. This utility model uses the displacement of the spheres to move the connecting rods, applying pressure to the hollow rubber ring, causing it to deform. The deformed hollow rubber ring pushes the sealing gasket upwards, making the sealing gasket tightly fill the gap between the overlapping edge and the connecting groove, thereby significantly improving the sealing performance at the connection between the two trenches and effectively preventing water leakage from the joint.

Description

Technical Field

[0001] This utility model relates to the field of drainage structure technology, and in particular to a temporary drainage structure for road reconstruction. Background Technology

[0002] During the reconstruction of municipal roads, in order to avoid the accumulation of rainwater in low-lying areas and to ensure that there is no water accumulation on the road surface during construction, it is usually necessary to set up temporary drainage structures along both sides of the road and in low-lying areas to concentrate the rainwater runoff and discharge it outside the construction area.

[0003] Currently, the most common temporary drainage structure uses prefabricated drainage ditches. During installation, a trench is dug in the ground beforehand, and then the prefabricated drainage ditches are arranged in sequence and embedded in the trench. The openings of the prefabricated drainage ditches face upwards, and several prefabricated drainage ditches are fixed together by connectors. After the prefabricated drainage ditches come into contact, the contact surface of the prefabricated drainage ditches is rough, resulting in poor sealing at the connection, which makes the temporary drainage structure prone to leakage at the connection of adjacent prefabricated drainage ditches. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as poor sealing at the joints, which makes the temporary drainage structure prone to leakage at the joints of adjacent prefabricated drainage ditches. Therefore, a temporary drainage structure for road reconstruction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a temporary drainage structure for road reconstruction, including a ditch. Several connecting screws are connected to the upper end of the ditch, and grating plates are inserted between the connecting screws. A connecting groove is formed on one side of the ditch, and an overlapping edge is fixedly connected to the other side of the connecting groove. A first groove is formed at the upper end of the overlapping edge, and a sealing gasket is connected inside the first groove. A hollow rubber ring is fixedly connected to the bottom end of the sealing gasket. Several second grooves are formed on one side of the overlapping edge, and a sphere is provided in each second groove. A connecting rod is fixedly connected to one side of each sphere, and one end of each connecting rod extends into the first groove. A fixing member is connected to the upper end of the ditch.

[0007] Preferably, the sealing gasket is a corrosion-resistant elastic rubber sealing gasket.

[0008] Preferably, the sealing gasket and the hollow rubber ring are an integral structure.

[0009] Preferably, one end of each connecting rod is fixedly connected to a compression block.

[0010] Preferably, the fixing member includes a limiting groove, the limiting groove being provided to the upper end of the groove, a U-shaped plate being inserted into the limiting groove, and a handle being fixedly connected to the upper end of the U-shaped plate.

[0011] Preferably, the U-shaped plate is made of stainless steel.

[0012] Preferably, a filter mechanism is connected between the connecting screws on the same side. The filter mechanism includes a fixing plate, which is connected between the two connecting screws. Several stop bars are connected at equal intervals along the length direction at the upper end of the fixing plate.

[0013] Preferably, some of the aforementioned levers are arranged perpendicularly to the fixed plate.

[0014] The temporary drainage structure for road reconstruction proposed in this utility model has the following advantages:

[0015] The displacement of the sphere drives the connecting rod to move and apply pressure to the hollow rubber ring, causing it to deform. The deformed hollow rubber ring pushes the sealing gasket upward, making the sealing gasket tightly fill the gap between the overlap edge and the connecting groove, thereby significantly improving the sealing performance of the connection between the two grooves and effectively preventing water leakage from the joint.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-5 A temporary drainage structure for road reconstruction includes a ditch 1, with several connecting screws 2 connected to the upper end of the ditch 1. A grid plate 3 is inserted between the connecting screws 2. A fixing nut 4 is connected to each connecting screw 2. A connecting groove 5 is opened on one side of the ditch 1. An overlapping edge 6 is fixedly connected to the other side of the connecting groove 5. A first groove 7 is opened at the upper end of the overlapping edge 6. A sealing gasket 8 is connected in the first groove 7. The sealing gasket 8 is a corrosion-resistant elastic rubber sealing gasket. A hollow rubber ring 9 is fixedly connected to the bottom end of the sealing gasket 8. The sealing gasket 8 and the hollow rubber ring 9 are an integral structure. Several second grooves 10 are opened on one side of the overlapping edge 6. A ball 11 is provided in each second groove 10. A connecting rod 12 is fixedly connected to one side of each ball 11. One end of each connecting rod 12 extends into the first groove 7. A pressing block 13 is fixedly connected to one end of each connecting rod 12. A fixing member 14 is connected to the upper end of the ditch 1.

[0024] Work process:

[0025] During installation, the overlapping edge 6 is inserted into the connecting groove 5 of another groove 1. When the overlapping edge 6 moves to the predetermined depth, the ball 11 contacts the inner wall of the connecting groove 5. As it continues to advance, the inner wall of the connecting groove 5 squeezes the ball 11, forcing the ball 11 to gradually retract into the second groove 10. During this process, the displacement of the ball 11 drives the connecting rod 12 to move. The connecting rod 12 further pushes the extrusion block 13. The movement of the extrusion block 13 applies pressure to the hollow rubber ring 9, causing it to deform. The deformed hollow rubber ring 9 pushes the sealing gasket 8 upward, so that the sealing gasket 8 tightly fills the gap between the overlapping edge 6 and the connecting groove 5, thereby significantly improving the sealing performance at the connection of the two grooves 1 and effectively preventing water leakage from the joint.

[0026] After the grooves 1 are connected, the two grooves 1 are locked together by the fastener 14 to ensure that they are in a stable pressing state. Finally, the grating plate 3 is installed onto the connecting screw 2.

[0027] Example 2: When fixing the two grooves 1, it is inconvenient to fix them quickly, refer to... Figure 3 As another preferred embodiment of the present utility model, the difference from embodiment 1 is that the fixing member 14 includes a limiting groove 141, the limiting groove 141 is provided to the upper end of the groove 1, a U-shaped plate 142 is inserted into the limiting groove 141, the U-shaped plate 142 is a stainless steel plate, and a handle member 143 is fixedly connected to the upper end of the U-shaped plate 142.

[0028] When fixing the two grooves 1, hold the handle 143 with your hand, and drive the U-shaped plate 142 to move through the handle 143, so that the two ends of the U-shaped plate 142 are inserted into different limiting grooves 141 respectively, thereby fixing the two grooves 1. The two grooves 1 are easy to fix.

[0029] Example 3: During drainage, large debris in the water tends to accumulate at the upper end of the grating plate 3, thus affecting the water flow through the grating plate 3. (Refer to...) Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a filter mechanism 15 is connected between the connecting screws 2 on the same side. The filter mechanism 15 includes a fixing plate 151, which is connected between the two connecting screws 2. A plurality of baffles 152 are connected at equal intervals along the length direction at the upper end of the fixing plate 151. The baffles 152 are perpendicular to the fixing plate 151. The connecting screws 2 limit and fix the fixing plate 151, and the fixing plate 151 fixes the baffles 152. The baffles 152 block large debris in the water and prevent large debris from accumulating at the upper end of the grid plate 3.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
