Road subsiding green belt and construction method

Abstract

The invention relates to a road subsiding green belt. Multiple curbstone and multiple n-shaped vertical curbstone are arranged on the left side and the right side of the green belt correspondingly. The left sides of the curbstones and the right sides of the n-shaped vertical curbstones are provided with a bicycle lane and a motor vehicle lane at a certain inclination angle correspondingly. An overflowing gutter inlet is formed in the green belt. A filter screen used for filtering sundries is arranged at the top of the overflowing gutter inlet. The bottom of the overflowing gutter inlet is connected with a gutter inlet connecting pipe. The bottom of the gutter inlet connecting pipe is connected with a rainwater pipeline. Prefabricated flow stop weirs are fixed to a subsiding green belt structure through flow stop weir end tenons and fixing soil nails, stability is good, and the structure is prevented from being damaged. The prefabricated flow stop weirs are arranged in the subsiding green belt, the construction speed is increased, meanwhile, the prefabricated flow stop weirs can prevent rainwater from scouring soil in the green belt, and water and soil losses are reduced.

Description

technical field [0001] The invention relates to the technical field of pavement road engineering, in particular to a road sunken green belt and a construction method. Background technique [0002] Driven by urbanization and industrialization, my country's material conditions and economic level have undergone a qualitative leap. However, in the process of rapid but unhealthy urbanization, we have long faced environmental problems such as urban waterlogging, rainwater runoff pollution, and ecological environment deterioration. Therefore, we urgently need an environmental protection measure that can not only realize the accumulation, infiltration and purification of rainwater in the urban area, but also ensure the safety of urban drainage and waterlogging prevention. In order to improve the utilization rate of rainwater resources and improve the ecological environment protection mechanism, the design concept of "sponge city" came into being. [0003] The existing green belts s...

Problems solved by technology

At present, there are green belts on both sides of some roads and on both sides of the walking road in the garden, and drainage ditches are set outside the green belts. In rainy days, the rainwater on the road will first pass through the green belts and then flow into the drainage ditch, which will drain the green belts. The surface soil, leaves, etc. rush into the drainage ditch, which will easily lead to soil erosion, siltation in the drainage ditch, etc., and the surface nutrients in the green belt will also be lost. At the same time, the road rainwater carries a large amount of soil into the rainwater pipe, causing the rainwater pipe to be blocked.
