Description

Technical Field

[0001] The utility model relates to the technical field of bridge drainage, in particular to a bridge drainage leakage prevention structure. Background Art

[0002] Bridges are indispensable road structures in modern urban construction. They can be used for walking and driving by people and vehicles. People attach great importance to the safety of bridges. In rainy weather, in order to avoid excessive accumulation of water on the bridges, which would pose a safety hazard to vehicle driving, drainage devices are now added to bridge construction. The drainage devices in bridge construction generally choose to drain water through the concrete structure inside the bridge.

[0003] After searching, a Chinese patent discloses a bridge drainage structure (authorization announcement number CN207582299U), including a bridge body and bridge pillars supporting it, water holes are set on both sides of the bottom plate of the bridge body to discharge the accumulated water on the bridge body, and a water pipe sealed and connected to the water hole is set at the lower end of the bridge body. The water pipes located on one side of the bridge body are all connected to a manifold, and the lower end of the manifold is connected to a vertical drainage pipe with a stirring device arranged inside. The stirring device rotates when the drainage pipe discharges water. Although the patented technology has a reasonable structure, the stirring device is driven by the impact of the discharged water flow to clean the drainage pipe, thereby preventing mud, sand and dust from accumulating in the drainage pipe and clogging the drainage pipe.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when a car passes over the above bridge, it will cause certain vibrations to the bridge itself, and will also cause the water pipe connections inside the bridge concrete to vibrate and cause them to loosen, thereby causing water leakage. Once the water flows into the concrete, it may cause the concrete to be corroded, resulting in a series of adverse effects such as dents on the surface of the bridge body. Utility Model Content

[0005] In view of the existing technology, when a car passes over the above-mentioned bridge, it will cause certain vibrations to the bridge itself, and will also cause the water pipe connections located inside the bridge concrete to vibrate and cause them to loosen, thereby causing water leakage. Once the water flow enters the concrete, it may cause the concrete to be corroded, causing depressions on the surface of the bridge body and a series of other adverse effects. The main purpose of the utility model is to provide a bridge drainage and leakage prevention structure.

[0006] The technical solution of the utility model is as follows: a bridge drainage and leakage prevention structure, including a fixed seat, a first drain pipe and a second drain pipe are slidably connected inside the fixed seat, arc blocks are arranged on both sides of the first drain pipe and the second drain pipe, both ends of the interior of the fixed seat are provided with limiting grooves used in conjunction with the arc blocks, the arc blocks are slidably connected to the inner walls of the corresponding limiting grooves, threaded rods are rotatably connected on both sides of the fixed seat, movable disks are threadedly connected on the outer sides of the threaded rods, connecting rods are rotatably connected on both sides of the movable disk, the arc blocks are rotatably connected to one end of the connecting rod away from the movable disk, a first sealing mechanism is arranged on the side close to the first drain pipe and the second drain pipe, and a second sealing mechanism is arranged on the inner walls of the first drain pipe and the second drain pipe.

[0007] By adopting the above technical solution, the movement of the movable plate is driven by the rotation of the threaded rod, which in turn can drive the rotation of the connecting rod, thereby driving the arc block to slide in the limiting groove, so that the first drain pipe and the second drain pipe can be quickly connected, and during the connection process, the first drain pipe and the second drain pipe can be more tightly connected.

[0008] As a preferred embodiment, the first sealing mechanism includes a fixing ring 2 fixedly connected to the inner wall of the second drain pipe, a first sealing ring is fixedly connected to the side of the fixing ring 2 close to the first drain pipe, a fixing ring 1 is fixedly connected to the inner wall of the first drain pipe, a first sealing groove used in conjunction with the first sealing ring is provided on the side of the fixing ring 1 close to the fixing ring 2, and the first sealing groove is clamped with the first sealing ring.

[0009] By adopting the above technical solution, through the coordinated use of the first sealing ring and the second sealing groove, the sealing performance between the first drain pipe and the second drain pipe can be improved, thereby reducing water leakage at the connection.

[0010] As a preferred embodiment, the second sealing mechanism includes a second sealing ring fixedly connected to the outside of the first drain pipe, and a second sealing groove for use with the second sealing ring is opened on the side of the second drain pipe close to the first drain pipe, and the second sealing ring is snap-connected to the second sealing groove.

[0011] By adopting the above technical solution and using the second sealing ring in conjunction with the second sealing groove, the sealing performance between the first drain pipe and the second drain pipe can be further improved.

[0012] As a preferred embodiment, mounting seats are fixedly connected to both sides of the arc block, two bolts are threadedly connected to the interior of the mounting seats, and the mounting seats are respectively connected to the first drain pipe and the second drain pipe through bolts.

[0013] By adopting the above technical solution and using two bolts, the arc block can be fixedly installed on the outside of the first drain pipe and the second drain pipe respectively.

[0014] As a preferred embodiment, the outer sides of the fixing seat, the first drain pipe and the second drain pipe are coated with a corrosion-resistant layer, and the corrosion-resistant layer is a zinc-rich paint.

[0015] By adopting the above technical solution and using zinc-rich paint, the corrosion resistance of the fixing seat, the first drain pipe and the second drain pipe can be improved.

[0016] As a preferred implementation, one end of the threaded rod away from the fixing seat is fixedly connected with an adjusting knob.

[0017] By adopting the above technical solution, the threaded rod can be driven to rotate.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, when the first drain pipe and the second drain pipe need to be installed, the threaded rod can be rotated to drive the movement of the movable plate, and then the connecting rod can be driven to rotate, so that the arc block can be driven to slide in the limiting groove, so that the first drain pipe and the second drain pipe can be quickly connected, and the first sealing mechanism and the second sealing mechanism can be connected more tightly during the connection process of the first drain pipe and the second drain pipe. After the device is installed, concrete can be poured to seal the threaded rod, and water leakage is not easy to occur.
