Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to reinforced concrete drainage pipes with flood discharge structures. Background Technology

[0002] Urban expansion is accompanied by large-scale infrastructure construction. Large areas of green space and farmland have been replaced by buildings, roads, and plazas. These artificial structures are mostly made of impermeable materials, hindering the natural infiltration of rainwater into the ground. Rainwater must be discharged through drainage pipes. While urban drainage systems are built to design standards and can meet drainage needs when cities are small, they become increasingly inadequate to cope with rising rainwater volumes as cities develop. Heavy rainfall in short periods puts immense pressure on urban drainage systems. Traditional reinforced concrete drainage pipes, limited by diameter and drainage capacity, cannot discharge large amounts of rainwater in time, leading to urban flooding. Flooding not only affects urban traffic and damages infrastructure but also causes serious losses to residents' lives and property, even threatening their safety. Reinforced concrete drainage pipes with flood discharge structures play a crucial role in protecting water resources. During flood season, they can discharge floodwaters in an orderly manner, preventing floods from flowing freely in cities or other areas and reducing pollution and damage to water sources.

[0003] The reinforced concrete drainage pipe structure with flood discharge includes the pipe body, flood discharge outlet, filter screen, reinforcing structure, and interface. However, during flood discharge, the impact force of high-speed water flow can damage the pipe body and flood discharge outlet. Existing technologies improve the structural strength and impact resistance of the connection by strengthening the structural design of the pipe body and flood discharge outlet, increasing the steel reinforcement and reinforcing ribs around the flood discharge outlet, and conducting regular structural inspections of the pipe body to promptly identify potential structural problems and repair and reinforce them to solve the problem of pipe body structural damage. However, the pipe connection method is complicated to install, consumes time and manpower, and is difficult to disassemble when the pipe needs maintenance, repair, and replacement, increasing maintenance costs and difficulty.

[0006] As a further description of the above technical solution:

[0007] The closing mechanism includes two L-shaped frames, the bottom of which is fixedly connected to the top of the reinforcing steel drainage pipe.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes multiple positioning posts, the outer walls of which are fixedly connected to the middle of the connecting pipe. Multiple positioning holes are opened on the right side of the steel drain pipe, and the right side of the positioning post engages with the inner wall of the corresponding positioning hole.

[0010] As a further description of the above technical solution:

[0011] The installation assembly includes two installation blocks. The adjacent sides of the installation blocks are fixedly connected to the front and rear sides of the steel drainage pipe. The right ends of the front and rear sides of the positioning hole are both fixedly connected to installation blocks.

[0012] As a further description of the above technical solution:

[0013] The sliding assembly includes two H-shaped blocks, with one adjacent side of the H-shaped block slidably connected to the opposite side of the mounting block, and an L-shaped plate rotatably connected to the left side of each H-shaped block.

[0014] As a further description of the above technical solution:

[0015] The fixing component includes fastening bolts. Fastening bolts are slidably connected to the left side of the second mounting block. The left side of the L-shaped plate has a mounting hole.

[0019] The top of the positioning hole is connected to a cleaning port, the top of the cleaning port is threaded with a sealing cap, and the bottom of the cleaning port is fixedly connected with a sealing gasket.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the connecting pipe is engaged with the positioning hole on the left side of the steel drainage pipe through the positioning column to achieve the initial fixing effect. Then, the H-shaped block on the outer side of the first mounting block is slid to slide into the inner side of the second mounting block to achieve the initial limiting. Finally, the L-shaped plate is rotated to engage the second mounting block, and the fastening bolt passes through the mounting hole to achieve the fixed installation effect. This reduces the installation difficulty and allows for convenient disassembly during maintenance and replacement. The filter plate inside the connecting pipe achieves the filtration effect, preventing pollution to the surrounding environment.

[0022] 2. In this utility model, by pulling up the positioning pin to release the engagement with the left hole, the baffle can be rotated. After opening the right side of the steel drain pipe, the positioning pin is released to engage with the right hole, thus opening the baffle. This effectively prevents the baffle from being accidentally opened due to the external force of water flow impact. At the same time, by engaging the positioning pin with the right hole, the baffle can be kept firmly in the open position, ensuring the stability of the flood discharge process and avoiding the impact of baffle shaking and displacement on the flood discharge effect.

The outer wall of each positioning post 5 is fixedly connected to the middle of the connecting pipe 4 to ensure the stability and reliability of the positioning post 5. The right side of the steel drain pipe 1 has multiple positioning holes 3, the size of which matches the positioning post 5. The right end of the positioning post 5 engages with the inner wall of the corresponding positioning hole 3 to achieve a positioning effect. The fixing plate 13 provides additional support. There is a sliding push rod 14 in the middle of the fixing plate 13, which can push the baffle 202 to rotate, facilitating the opening of the baffle 202.

[0040] Working principle: Connecting pipe 4 is engaged with positioning hole 3 on the left side of steel drain pipe 1 through positioning post 5 to achieve initial fixation. Then, H-shaped block 8 on the outside of installation block 1 7 is slid in to slide into the inside of installation block 2 10 to achieve initial positioning. Finally, L-shaped plate 9 is rotated to engage installation block 2 10, and fastening bolt 12 passes through installation hole 11 to achieve fixed installation. The operation is simple and quick, reducing installation difficulty and improving construction efficiency. It does not require a lot of time for alignment and adjustment, making it suitable for large-scale pipeline installation projects. It can also be easily disassembled during maintenance and replacement. In addition, the filter plate 6 achieves filtration during flow, which can prevent large debris from accumulating and rotting in the pipeline, thereby reducing odors and harmful gases caused by the rotting of debris and preventing pollution to the surrounding environment.

[0041] By pulling up the positioning pin 207 to release its engagement with the left hole 204, the baffle 202 can be rotated. After opening the right side of the steel drain pipe 1, the positioning pin 207 is released, causing it to engage with the right hole 204, thus opening the baffle 202. This effectively prevents the baffle 202 from being accidentally opened due to the external force of water flow. When the baffle 202 is rotated to the open position, the engagement of the positioning pin 207 with the right hole 204 ensures that the baffle 202 remains firmly in the open position, guaranteeing the stability of the flood discharge process and preventing the flood discharge effect from being affected by the shaking or displacement of the baffle 202.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
