Description

Technical Field

[0001] This utility model relates to the field of bridge drainage technology, and in particular to a bridge drainage line structure. Background Technology

[0002] A bridge is a structure built to cross natural or man-made obstacles, spanning rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, substructure, and ancillary structures. The superstructure mainly refers to the bridge span structure and bearing system; the substructure includes abutments, piers, and foundations. Bridge drainage pipes remove accumulated water from the bridge surface, preventing water buildup that could affect friction and impede vehicle movement. Generally, bridge drainage uses cast iron pipes connected to PVC drainage pipes for relay drainage.

[0003] In existing bridge drainage systems, the drainage pipes are typically circular. During installation, these circular pipes are fixed to the structural surface at only one support point, increasing the risk of pipe falling or deforming during drainage. Furthermore, circular drainage outlets generate upward convection under high-speed water flow, reducing drainage capacity. Additionally, the connection between drainage pipes relies solely on a single fitting for surface fixation, failing to achieve seamless integration. Therefore, this application provides a bridge drainage system structure to meet these requirements. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a bridge drainage line structure to address the issue that existing drainage pipes are typically circular pipes. During installation, circular pipes are fixed to the structural surface at only one support point, which increases the risk of pipe falling and deformation during drainage. Furthermore, circular drain outlets generate upward convection under high-speed water flow, resulting in reduced drainage volume. Additionally, the connection between drainage pipes is only surface-fixed through a single fitting, making seamless connection impossible.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A bridge drainage system structure includes a bridge body. A drain outlet is provided on one side of the surface of the bridge body, and a drainage stabilizing mechanism is installed on the inner side and below the drain outlet. The drainage stabilizing mechanism includes a water collection pipe end and a pipe clamp bracket. An insert block is fixedly provided on the inner side of the upper end of the water collection pipe end, and an iron filter plate is embedded above the insert block. An adjustment assembly mechanism is installed on the outer side of the pipe clamp bracket, and an adapter mechanism is installed inside and on one side of the pipe clamp bracket. The water collection pipe end is fixedly installed in the middle of the drain outlet. A first drain pipe is fixedly connected to the end of the water collection pipe end, and a sealing component is installed at the end of the first drain pipe. The sealing component includes a flow-blocking frame, and installation components are installed on both sides of the flow-blocking frame and the first drain pipe. A second drain pipe is fixedly provided at the lower end of the flow-blocking frame, and a pipe clamp bracket is installed on the outer side of a section of the second drain pipe.

[0007] Optionally, the sealing assembly includes a flow-blocking frame, which is fixed to the top of the second drain pipe. A mounting frame is fixed to the inner side of the flow-blocking frame, and a baffle is fixed to the upper inner side of the mounting frame. A first sealing gasket is installed in the mounting area formed between the mounting frame and the baffle, and a second sealing gasket is fixed to the end of the first drain pipe.

[0008] Optionally, the first sealing gasket and the second sealing gasket are sized to fit together.

[0009] Optionally, the installation component includes a first screw groove, which is symmetrically opened on both sides of the end section of the first drain pipe. The flow-blocking frame has second screw grooves on both sides, and a first locking screw is screwed into the middle of the second screw groove.

[0010] Optionally, the adjustment assembly mechanism includes an adjustment component, which is installed on one side of the pipe clamp bracket. The adjustment component includes two guide brackets, and the ends of the two guide brackets are connected to an assembly plate. The assembly component is installed on the four periphery of the assembly plate.

[0011] Optionally, the adjustment assembly includes inner guide rods, which are symmetrically fixed on both sides of one side of the pipe clamp bracket. The inner sides of the two inner guide rods are provided with slots, and a guide frame is provided around one section of the two inner guide rods. A connecting frame is fixed inside one section of the two guide frames, and a fixing block is fixed in the middle of the connecting frame. Return springs are fixed on both sides of the fixing block, and hand-held blocks are fixed at the top of the two return springs. A locking rod is fixed on one outer section of the two hand-held blocks, and guide rods are provided on both sides of the connecting frame.

[0012] Optionally, the guide rod and the hand-held block are connected by a movable guide, and the dimensions of the locking rod fixed on the outer side of a section of the hand-held block and the locking groove provided on the inner side of the inner guide rod are matched.

[0013] Optionally, the assembly component includes a third screw groove, and the third screw grooves are distributed on the four periphery of the assembly plate, with a second locking screw screwed in the middle of the four third screw grooves.

[0014] Optionally, the adapter mechanism includes an inner groove, which is located in the middle of the pipe clamp holder. A positive and negative lead screw is installed in the middle of the inner groove, and lead screw sleeves are screwed on both sides of the middle of the positive and negative lead screws. A limiting guide is fixed on the inner side of the two lead screw sleeves. A sliding groove for guiding the limiting guide is provided in the middle of the inner side of the inner groove. A toothed block is provided around one end of the positive and negative lead screw, and an adjusting sleeve is installed around the toothed block. An aligning toothed groove is provided on the inner side of the adjusting sleeve.

[0015] Optionally, the toothed block provided around one end of the positive and negative lead screws is sized to match the alignment toothed groove provided inside the adjusting sleeve.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a drainage stabilization mechanism, both ends of the water collection pipe are integrally and fixedly connected to the drain outlet and the first drainage pipe, respectively. These three are a whole, so when water flows downward from the highest point, it cannot seep into the structural layer of the bridge itself. Moreover, with the fixed flow guidance of the first drainage pipe, there will be no leakage or splashing during the drainage process. The connection between the first drainage pipe and the second drainage pipe is equipped with a sealing component and an installation component. The first sealing gasket is embedded in the middle of the mounting frame inside the flow-blocking frame where they are connected, and a second sealing gasket is fixed at the end of the first drainage pipe. When the two pipes are connected, the second sealing gasket can fit perfectly against the first drainage pipe. The threaded structure on the sealing gasket, in conjunction with the mounting components, ensures a tight seal between the first and second drainage pipes, preventing any leakage. Next, pipe clamps are installed around one section of the second drainage pipe to connect the structural surface and the pipe body. This increases the pipe's stability during drainage, preventing it from falling off or deforming. Furthermore, the rectangular design of the pipes increases drainage volume and speed. When air is impacted by the water flow, it flows towards the inner corner of the pipe, avoiding direct resistance and preventing upward convection. This efficiently increases drainage volume and enhances the safety of the bridge itself.

[0018] By setting an adjustable assembly mechanism, when the distance between the pipe clamp bracket and the required assembly surface is far, the operator can use two fingers to pinch the two hand blocks on one side of the bracket connected to the middle of the two guide brackets. At this time, under the compression of their respective connected return springs, the two hand blocks cooperate with the guide rod to drive the two clamp rods to disengage from the corresponding slots inside the inner guide rods. The operator can then adjust the extension length of the two inner guide rods and the guide brackets in sequence. After adjustment, slowly release the hand so that the two clamp rods are locked into the corresponding slots of the two inner guide rods to form a stable limit. This adjusts the distance between the pipe clamp bracket and the structural surface. After adjustment, the assembly plate can be securely installed on the structural surface using the assembly components.

[0019] By setting up an adaptation mechanism, when dealing with pipes of different sizes, personnel can manually rotate the adjusting sleeve to rotate the positive and negative screws. In this state, the screw sleeves interacting with the screws can move relative to each other with their fixed limiting guides and guides from the sliding grooves. This allows the two limiting guides to be adapted to the fixed limiting of pipes of different sizes. After adjustment, personnel can use the fit between the alignment toothed groove on the inner side of the adjusting sleeve and the toothed block on one end of the positive and negative screws to detach the adjusting sleeve from the screws. The adjusting sleeve can then be carried during subsequent maintenance, thus avoiding unauthorized adjustments by outsiders and improving safety. Attached Figure Description

[0036] The working principle of the technical solution provided by this utility model is as follows:

These three are a whole, so when water flows downward from the highest point, it cannot seep into the structural layer of the bridge itself.

Then, a pipe clamp 36 is installed around a section of the second drainage pipe 35 to connect the structural surface and the pipe body. This increases the stability of the pipe during drainage, preventing detachment and deformation. Furthermore, the rectangular design of the pipe increases the drainage volume and speed. When air is impacted by the water flow, it flows towards the inner corner of the pipe, avoiding direct resistance and preventing upward convection. This efficiently increases the drainage volume and enhances the safety of the bridge. The pipe clamp 36... When the distance between the position and the required assembly surface is far, the operator can use two fingers to pinch the two hand blocks 617 on one side of the connecting frame 614 connected to the middle of the two guide frames 613. At this time, under the compression of their respective connected return springs 616, the two hand blocks 617 cooperate with the guide rod 619 to guide and drive the two locking rods 618 to disengage from the corresponding slots 612 inside the inner guide rods 611.

After adjustment, slowly release the hand so that the two locking rods 618 are locked into the corresponding slots 612 of the two inner guide rods 611 to form a stable limit. This adjusts the distance between the pipe clamp 36 and the structural surface. After adjustment, the assembly component 6 is used. 3. Securely install the assembly plate 62 onto the structural surface. Finally, when different sizes of pipes are involved, personnel can manually rotate the adjusting sleeve 77 to rotate the positive and negative screw 72. In this state, the screw sleeve 73, which interacts with the screw, can move relative to the screw with its fixed limiting guide 74 and guide it with the sliding groove 75. This allows the two limiting guides 74 to be adapted to the fixed limiting of different sizes of pipes. After adjustment, personnel can use the matching toothed groove 78 on the inner side of the adjusting sleeve 77 and the toothed block 76 on one side of the positive and negative screw 72 to disengage the adjusting sleeve 77 from the positive and negative screw 72.
