Description

Technical Field

[0001] This application relates to the field of municipal siphon drainage technology, and in particular to a modular self-adjusting siphon drainage pavement system. Background Technology

[0002] When implementing self-regulating siphon drainage for road surfaces, a modular self-regulating siphon drainage pavement system is often used. This system is composed of prefabricated modules and can automatically adjust the siphon effect according to the water accumulation to achieve rapid drainage. It can efficiently remove road water, reducing traffic congestion, vehicle skidding, and other safety hazards caused by water accumulation. Its modular design makes installation and maintenance more convenient, reduces construction costs and difficulty, and can adapt to different road conditions and climates, improving road durability and ensuring good road performance in various environments. This system is used because traditional drainage methods suffer from low drainage efficiency, easy clogging, and difficult maintenance, while it better meets the requirements of modern roads for rapid drainage and long-term stable operation.

[0003] The modular self-adjusting siphon drainage pavement system, through its integrated modular design, can automatically adjust the drainage speed according to the water accumulation situation, quickly remove water from the road surface using the siphon principle, while maintaining a compact structure and easy installation, ensuring that the road can quickly restore its traffic capacity under various weather conditions.

[0004] In existing modular self-regulating siphon drainage pavement systems, most siphon drainage pavements use fixed filters or simple grilles to intercept impurities. These filtration structures can only trap larger particulate pollutants and are ineffective at filtering fine impurities such as mud, sand, and leaf debris. This can easily lead to blockage of drainage channels, weaken the siphon effect, and affect drainage efficiency. At the same time, traditional filtration devices are often fixedly connected to the drainage system, requiring disassembly of the entire structure for maintenance and cleaning. This operation is complex, time-consuming, and labor-intensive, increasing maintenance and time costs. Therefore, a modular self-regulating siphon drainage pavement system is proposed to solve the above problems. Utility Model Content

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0040] Example: A modular self-adjusting siphon drainage pavement system, referring to Figure 1 and Figure 3 The system includes a road surface 1, which also guides rainwater to the drainage mechanism 2. During the rainwater discharge process, it can effectively prevent rainwater from scouring and eroding the soil around the road and protect the stability of the road foundation. The drainage mechanism 2 is installed on the inner side of the top of the road surface 1. When rainwater falls on the road surface, due to the slope of the inner side of the top of the road surface 1, the rainwater will naturally flow to the inlet of the drainage mechanism 2. After the grid of the inlet intercepts debris, the rainwater flows along the guide channel and enters the collection box 3 through the connecting pipe 7 under the action of gravity.

[0041] Specifically, the road surface 1 and the drainage mechanism 2 are connected. The inner top of the road surface 1 has a slope, which can guide rainwater to the inlet of the drainage mechanism 2. The inlet grille can intercept debris. Rainwater enters the collection box 3 under the action of gravity through the diversion channel and connecting pipe 7. When rainwater is discharged, it can prevent rainwater from washing away and eroding the soil around the road, and protect the stability of the road foundation.

[0042] A collection box 3 is fixedly connected to the internal space of the road body 1 to collect rainwater from various drainage wells 26 for centralized storage and treatment. During the rainwater discharge process, the collection box 3 can regulate the water volume. When the rainfall is large, it can temporarily store excess rainwater to relieve drainage pressure. When the rainfall is small, it can slowly discharge the stored rainwater to maintain stable drainage operation. A shut-off mechanism 4 is set on one side of the outside of the collection box 3 to control the discharge of rainwater in the collection box 3. The drainage flow rate is flexibly adjusted according to the amount of rainwater, water level and other conditions. Under normal circumstances, the shut-off mechanism 4 is in the open state to allow rainwater to be discharged smoothly. In case of emergency such as heavy rain, the shut-off mechanism 4 can be automatically closed by the control unit to prevent excessive rainwater discharge and waterlogging.

When the rainfall is light, it slowly discharges the stored rainwater to maintain stable drainage operation. A shut-off mechanism 4 is set on one side of the outside of the collection box 3 to control the rainwater discharge inside the box. It can flexibly adjust the drainage flow according to the amount of rainwater, water level and other conditions.

The shut-off mechanism 4 outside the collection box 3 can control the rainwater discharge according to the amount of rainwater and the water level. Under normal circumstances, the shut-off mechanism 4 is open to allow rainwater to be discharged. In case of emergency such as heavy rain, it is automatically closed to prevent flooding.

[0063] The motor 431 drives the transmission shaft 432 to rotate, which in turn drives the butterfly valve 434 to rotate via the rotating rod 433, thereby controlling the opening and closing of the outlet pipe 42 and the drainage flow. The sealing gasket 435 enhances the sealing performance at the joint between the butterfly valve 434 and the outlet pipe 42. The sealing ring 48 inside the outlet pipe 42 prevents leakage at the joint surface. At the same time, the positioning air pipe 5 in the collection box 3 discharges the air inside the pipe before the siphon starts. After the rainwater passes through the filter inlet pipe 6 to filter large particles of impurities, it enters the connecting pipe 7. The pressure pipe 8 on the left side of the connecting pipe 7 is filled with water by a high-level water tank or pump to quickly form a negative pressure at the initial stage of siphon start-up. The siphon drainage pipe 9 on the right side discharges the high-speed water flow formed by the siphon to the municipal pipe network, ultimately realizing the transportation of rainwater to the external drainage components through the outlet pipe 42.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
