Description
Technical Field
The application belongs to the technical field of road rainwater treatment, and particularly relates to a road rainwater storage and purification system for a non-concave machine non-isolation belt.
Background
The current popular road rainwater control method is to set a rainwater garden, a sinking green land and the like on two sides of a road, or to construct a green isolation belt into a concave shape, and then set the rainwater garden by combining with terrains so as to realize the effect of regulating and purifying the road rainwater. The common principle of a road rainwater garden is as follows:
as shown in fig. 8, in the conventional road sponge facility, the rainwater runoff passes through the road cross slope, enters the submerged rainwater garden through the vegetation buffer zone, then passes through the infiltration purification, enters the municipal rainwater pipe network through the blind pipe and the drainage rainwater pipe, and the out-of-standard rainwater is discharged through the overflow well. The facility has good effect of regulating and purifying the road rainfall runoff, and is widely applied. However, in actual engineering, the terrain where the rainwater garden is located is often a greenbelt which is raised or is flush with the road, and in order to obtain enough depressed storage space, a large excavation amount and sinking amount are required, so that the construction cost of sponge facilities is high. In addition, the landscape effect of the original green land is greatly reduced by excavating the original green land. Conventional road rain gardens often fail to function adequately due to a number of constraints.
In addition to traditional road stormwater gardens, some researchers are exploring other new road stormwater control systems. Chinese patent document CN206359928U discloses a "concave greenbelt structure applied to road machine non-isolation belt". The method is characterized in that sediment and impurities carried by road surface runoffs are intercepted by a groove structure of a sewage interception section of a concave green land; and densely planting shrubs at the connecting section of the dirt intercepting section and the concave section to effectively intercept garbage and floating suspended matters in road runoff. But this method has the following disadvantages: the system is not suitable for a mechanical non-isolation belt or a mechanical non-isolation belt of a non-concave road, has poor landscape effect and has large requirements on the section space of the whole system. Chinese patent document CN 108118769A discloses a "sponge city rainwater stagnating and storing purifying system". The method is that the sinking green land is led into a rainwater multifunctional collecting well and a deslagging and sand settling device, and the removal efficiency of suspended matters with the grain diameter of more than 125 mu m can reach 70 percent. But this method has the following disadvantages: is mainly suitable for rainwater purification, has high equipment cost and is not suitable for non-concave green lands.
The common mechanical and non-isolation belt in China is in a convex or level form with the road surface, and the construction form has good landscape effect, but is unfavorable for the construction of road sponge facilities. The traditional road sponge urban facilities all need a certain surface concave space, so that rainwater runoffs are converged to enter the sponge facilities during raining, and further collection and purification are performed. Therefore, in actual engineering, under the condition of encountering a non-recessed isolation belt, the construction of the road rainwater sponge facility cannot be easily realized, and in order to achieve the expected rainwater control effect, higher cost investment is required, and a larger construction space is reserved. In addition, due to the fact that a concave space is needed to be arranged in the construction of the traditional road sponge facility, the original landscape effect of the non-isolation belt of the machine is often damaged.
