Description

A new green belt water storage structure

technical field

The utility model belongs to the field of municipal greening engineering, in particular to a green belt water storage structure.

Background technique

In recent years, the global average temperature has gradually increased, leading to more and more extreme weather, such as the frequency of heavy rainfall has increased than before. Therefore, the pressure on urban drainage pipe network systems has become increasingly prominent. At present, the central green belt or the machine-non-separation belt in most cities in my country is often designed to be slightly higher than the road surface elevation. The green belt only plays the role of urban greening, and does not have the function of collecting rainwater and accelerating road drainage, resulting in municipal drainage. The drainage pressure of the pipe network is high, and the phenomenon of urban water accumulation is prone to occur when the rainfall is heavy, which has a serious impact on urban traffic.

Aiming at the design defects of traditional green belts, a patent application titled "A Green Belt Drainage Structure" and publication number CN105178208A discloses a method for accelerating the drainage speed of the road surface, that is, firstly introduce rainwater into the green belt, A permeable square pipe is arranged inside, and the permeable square pipe leads to the municipal drainage pipe. This method has a certain effect on speeding up the road drainage, but this method has the disadvantage of poor durability. The permeable square pipe adopts a permeable concrete structure, and the permeable concrete is prone to clogging. Lose the drainage effect; the name is "sinking type green belt and construction method thereof", and the patent application with publication number CN106069296A discloses a kind of green belt structure with water storage effect, a water storage pool is set at the bottom of the green belt, and a A controller with a central processing unit, an infrared human body sensing module, a voice prompt module, a color changing module, and a GSM remote module. When constructing according to this method, the project cost is much higher than the traditional construction method, the later maintenance cost of the control system is high, and the construction is complicated. At the same time, this method does not make a waterproof layer at the bottom of the green belt, and the rainwater is easy to seep into the road structure layer and soak the road structure. , resulting in cracks, thereby reducing the service life of the road.

2. Set up a reservoir at the bottom of the green belt, which can collect and store excess water in the green belt. At the same time, the setting of the sprinkler system realizes the secondary utilization of rainwater, which has the effect of energy saving and environmental protection, and improves the utilization rate of rainwater;

3. The setting of the anti-filter geotextile can prevent the planting soil in the green belt from affecting the water permeability of the reinforced concrete cover, and ensure that the water can pass through the reinforced concrete cover and infiltrate into the reservoir;

4. The setting of the drainage pipe can ensure that the excess water in the reservoir is discharged into the municipal drainage pipe network in time to prevent water accumulation in the green belt.
