Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, and in particular to a seepage-guiding and pressure-bearing composite road drainage structure. Background Technology

[0002] Traditional drainage relies excessively on underground pipe networks, which not only increases municipal construction and maintenance costs but also easily leads to resource waste. New drainage technologies are urgently needed to reduce reliance on pipe networks, reduce system pressure, and achieve the recycling of rainwater resources. The permeable and pressure-bearing composite structure, with its dual mechanism of internal road surface drainage and external diversion, can divert rainwater before it accumulates in large quantities, effectively relieving pressure on the pipe network and reducing the probability of urban flooding.

[0003] A search revealed Chinese Patent Publication No. CN220846920U, which discloses a wear-resistant pavement structure using anti-detachment small-particle-size damping drainage asphalt. This structure comprises an SBS modified asphalt layer, a small-particle-size drainage asphalt layer, an asphalt roll functional layer, and a damping structure layer. The wear-resistant pavement structure is a composite pavement structure, with the SBS modified asphalt layer, small-particle-size drainage asphalt layer, asphalt roll functional layer, and damping structure layer stacked sequentially from top to bottom. This composite pavement structure offers advantages such as strong mechanical properties and high wear resistance. The anti-detachment small-particle-size damping drainage asphalt layer significantly improves asphalt layer detachment and enhances drainage flow. The novel composite anti-detachment small-particle-size damping drainage asphalt wear-resistant pavement structure can improve the long-term durability of the pavement and reduce pavement maintenance costs. However, the installation of the drainage system involves cumbersome procedures and is prone to loose component connections due to inaccurate manual measurement and positioning.

[0030] Working principle: The positioning post 2072 engages with the positioning hole 2073, initially completing the installation of the drain plate 202 and the water collection tank 1.

This design prevents the drainage plate 202 from deforming and being damaged due to excessive local stress, extending the service life of the drainage structure and ensuring long-term stable drainage function. At the same time, when the water flows, debris is initially intercepted by the drainage plate 202 and then intercepted by the collection box 2091, preventing blockage inside the drainage system, ensuring unobstructed drainage channels, and protecting the safety of pedestrians and vehicles. The drainage plate 202 can be opened, and the collection box 2091 can be lifted by the handle 2092 to clean up the intercepted debris, reducing maintenance difficulty and cost, and minimizing the impact on traffic and the surrounding environment. The pipes are connected by connecting pipe 302 to drain pipe 301. The sealing sleeve 303 is fitted to drain pipe 301, and then the sliding adjusting ring 306 is fitted to the fixing ring 304. Finally, the fastening bolt 307 passes through the fixing ring 304 and engages with the fixing block 305 to achieve a fixed connection between drain pipe 301 and connecting pipe 302. There is no need for complicated measurement and angle adjustment. During installation, simply slide to the interface position and then fix it by adjusting ring 306, fixing ring 304 and fastening bolt 307. No professional equipment is required, which shortens the construction time and reduces the impact on traffic and residents' lives. At the same time, the structure is stable and can ensure the long-term stable operation of the drainage system and reduce safety hazards caused by leakage.
