Description

Seepage stagnation type storage regulation sponge parking lot

Technical Field

The utility model relates to a sponge city construction field especially relates to a novel infiltration type regulation and storage sponge parking area.

Background

The construction of the sponge city is conducted in China, the concept of the sponge city is continuously understood and accepted by people in the construction process, but with the promotion of the construction of the sponge city, the construction technology of the existing sponge city cannot face heavier working conditions, and particularly cannot effectively solve the problem that rainwater is stored in a parking lot in the sponge construction process.

The main theory in sponge city at present is at first through reducing the comprehensive net flow coefficient in the place thereby reduce the rainwater runoff, and the discharge that produces the runoff rainwater is reduced to the rethread LID retaining facility to reach the sponge city theory of "infiltration stagnation holds net usefulness row" in proper order. But when the idea is applied to a large parking lot, the ground is difficult to fall for the following reasons: firstly, a sponge city needs a large number of permeable facilities to reduce the comprehensive net flow coefficient of a site, the load intensity of the existing permeable facilities cannot reach the load intensity of the traditional non-permeable pavement of the same level, and the maintenance times and frequency of the parking lot are undoubtedly increased for the parking lot with frequent vehicle access; if the maintenance frequency and frequency of the parking lot are reduced, the elevation and grade of the materials used by the permeable facility must be increased, which is not different from the cost input of one-time construction. Secondly, the parking lot belongs to the place with a high hardening area and a small greening area, the greening space is often designed into a belt shape or a point shape, the water storage capacity of the sinking facilities made in the green lands is extremely limited, and the annual runoff total amount control rate required by the place is difficult to achieve, so that a water storage module needs to be built when the indexes are reached, excessive rainwater in the water storage module cannot be completely utilized, and the sponge is often discharged in order to prevent the water body from smelling, and the sponge does not exert the effect of the sponge in fact.

Chinese patent publication No. CN210714001U discloses an ecological parking lot for controlling rainwater runoff, wherein a rainwater garden planting area is arranged on a parking lot body, an anti-seepage membrane is arranged above an original soil layer on the bottom surface of the rainwater garden planting area, a water collecting blind pipe, a gravel layer, a filter layer and a planting soil layer are sequentially arranged above the anti-seepage membrane from bottom to top, and rainwater above the anti-seepage membrane is finally discharged into a municipal rainwater system. This solution has the following drawbacks:

(1) although the method can achieve the purpose of effective peak-shifting drainage, after rainwater permeates into the pebble bed, the rainwater cannot effectively permeate into the ground due to the impermeable membrane and the seepage pipes in the pebble bed, and the requirement of 'seepage in seepage stagnation storage and purification drainage' cannot be met. (2) Because the existence of a large amount of facilities that permeate water in the place leads to the inside of the facility that permeates water of a large amount of flowing water in the afforestation earth, has greatly improved the maintenance cost of nursery stock.

Chinese patent publication No. CN109296231A discloses a sponge ecological parking lot, which comprises a parking space, a plant box, a rainwater storage system and a watering and spraying system, wherein the parking lot collects rainwater with a large water tank, and then the rainwater is sprayed back to the site for recycling through a series of electric control systems with electric control and intelligent capabilities. The parking lot has the following disadvantages: (1) this parking area relies on digital systematic control to carry out the regulation of each item function of sponge completely, needs professional maintainer alignment to carry out periodic inspection and maintenance to need add a large amount of automatically controlled and digital equipment in the one-time construction process, make one-time construction cost and later maintenance expense all very high. (2) The running experience of sponge cities in this few years shows that after rainfall, green plants are irrigated and maintained for 2-3 days, rainwater can smell after being stored in underground water storage facilities for 2 days, and can become black and smelly after being stored for 5 days, so that the use of a parking lot can be influenced by peculiar smell caused by irrigation with the water body. (3) The rainwater is more in suspended substance, adopts the mode of sprinkling irrigation, little sprinkling irrigation to water, can produce great work load to watering facility, very easily damages equipment, consequently need frequently to block up and damage equipment and change, has increased the maintenance cost. (4) All control circuits of the scheme are distributed underground, and safety accidents such as electric leakage and the like are easy to happen if the control circuits are not maintained properly.

Chinese patent publication No. CN111395099A discloses a sponge ecological parking lot, which comprises a drainage system and a plurality of groups of parking units, wherein each group of parking units drains rainwater into a biological retention area, and then drains rainwater into a municipal rainwater system from the biological retention area. The parking lot has the following disadvantages: (1) the drainage areas of the plurality of groups of parking units are provided with vegetable layers, so that the maintenance difficulty is improved, and the device is not suitable for the condition of large load intensity of a parking lot. (2) The vegetation layer is coated by pervious concrete, the concrete is rigid, the plants cannot root downwards, and the vegetation maintenance difficulty is high. (3) The infiltration of rainwater only stops in the surface layer, and excessive rainwater can only be discharged into recycling system or rainwater pipe network, and plain soil layer has blockked rainwater infiltration, can't replenish groundwater, can't reach the requirement of "oozing stagnated and hold and arrange with arranging" middle "and ooze".

Therefore, the sponge parking lot which can be infiltrated, stagnated, stored and discharged in a real sense needs to be developed.
