Description

Sponge City Rainwater Comprehensive Utilization System

technical field

The utility model relates to a sponge city, in particular to a rainwater comprehensive utilization system for a sponge city.

Background technique

Sponge city is a new concept of urban construction proposed by the state. The Ministry of Housing and Urban-Rural Development requires that by 2020, more than 20% of the urban built-up area will meet the target requirements, and by 2030, more than 80% of the area will meet the target requirements. It can be seen from this that the country urgently needs to improve the living environment of residents and the urban water environment. The sponge city requires the city to have the functions of infiltration, stagnation, storage, purification, utilization and drainage when it rains. The proportion of road pavement in the whole city is about 30%, and there are problems of runoff pollution and water waste caused by rainwater scouring the road surface. Therefore, it is very important to give full play to the role of municipal roads and sidewalks in sponge cities.

At present, the construction of sponge cities has begun to be vigorously promoted and applied in China. Some of the existing sponge facilities are difficult to maintain and repair, and have no effect on rainwater utilization. The characteristics of infiltration, stagnation, storage, purification, use and discharge in sponge engineering have not been fully utilized. In particular, there is no reasonable realization of the utilization of rainwater resources.

Contents of the invention

The technical problem to be solved by the utility model is to provide a sponge city rainwater comprehensive utilization system, which can relieve the discharge pressure of the municipal pipe network when the rainstorm hits and increase the utilization rate of rainwater at the same time.

The technical solution adopted by the utility model to solve the technical problem is: to construct a sponge city rainwater comprehensive utilization system, including an ecological isolation pier, a rain garden, a permeable hose network, a drainage ditch, an integrated filter storage tank and a rainwater pipe;

Set up permeable bricks on the sidewalk surface, lay permeable hose nets under the permeable bricks, bury and install drainage ditches at the lower part of the sidewalk near the motorway, set up ecological isolation piers and permeable bricks in the square area, and bury an integrated filter water storage tank under the rain garden;

The square area filters and collects rainwater through permeable bricks and then flows into the water storage tank of the ecological isolation pier. The rainwater collected by the water storage tank is introduced into the ecological isolation pier through the buried water absorption strips to replenish water for the plants; the sidewalk passes through the permeable bricks and The rainwater collected by the permeable hose network flows into the rainwater pipe through the gutter, and the rainwater pipe is connected to the municipal pipe network and the integrated filter storage tank.

In the above solution, the permeable brick is a permeable brick with a replaceable filter element.

In the above solution, the drainage ditch is a replaceable seepage net drainage ditch. Implementation of the utility model sponge city rainwater comprehensive utilization system has the following beneficial effects:

The utility model can provide the required water resources for the public area, and also play a role in regulating and storing the discharge pressure of the rainwater municipal pipe network. The utility model has the advantages of low construction cost, energy saving and environmental protection, improves the efficiency of rainwater recycling, purification and utilization, improves the urban greening rate, and saves greening maintenance costs at the same time. Fully realize the functions of infiltration, stagnation, storage, purification, utilization and drainage in the sponge city.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

As shown in Figures 1-6, a sponge city rainwater comprehensive utilization system of the present invention includes an ecological isolation pier 1, a rain garden 3, a permeable hose network 4, a drainage ditch 5, an integrated filter storage tank 6 and a rainwater pipe 7.

Set permeable bricks 2 on the sidewalk surface, lay permeable hose net 4 under the permeable bricks, bury and install drainage ditches 5 at the lower part of the sidewalk near the motorway, set ecological isolation piers 1 and permeable bricks 2 in the square area, and bury integrated filtration under the rain garden 3 Water storage tank 6.

The square area filters and collects rainwater through the permeable bricks 2 and then flows into the water storage tank of the ecological isolation pier 1. The rainwater collected by the water storage tank is introduced into the ecological isolation pier 1 through the buried water absorption strips to replenish water for the plants. The rainwater collected by the sidewalk through the permeable bricks and the permeable hose network 4 flows into the rainwater pipe 7 through the gutter 5, and the rainwater pipe 7 is connected to the municipal pipe network and the integrated filter storage tank 6.

In this embodiment, the permeable brick 2 is a permeable brick 2 with a replaceable filter element, and the drainage ditch 5 is a replaceable seepage net drainage ditch 5 .

The utility model work process is as follows:

The square area filters and collects rainwater through replaceable permeable bricks 2 and flows into the aquifer and the invisible water storage tank of the ecological isolation pier 1.

The ecological isolation pier 1 introduces the collected rainwater through the capillarity principle through the embedded water-absorbing strips to replenish water for the plants. In the dry season, after the water level in the reservoir drops to the control line, the management room will replenish water to the invisible water storage tank through the water supply pipe.

The sidewalk area uses ordinary permeable bricks and a permeable hose network to speed up the infiltration of rainwater to ensure that the sidewalk can keep walking in rainy season without splashing water.

The rainwater infiltrated into the aquifer flows into the rainwater pipe network through the replaceable seepage net gutter 5 to further purify and filter the rainwater. The seepage net of the replaceable seepage net gutter 5 can be plugged and replaced, which is convenient for maintenance and replacement, and can ensure long-term and effective filtration of rainwater.

The collected, filtered and purified rainwater flows into the municipal pipe network through the rainwater pipe 7, and the excess purified rainwater flows into the gabion wall of the rain garden 3 to wash the gabion wall, and the washed rainwater flows into the rain garden 3 for watering.

The excess rainwater for irrigation will flow in through the overflow wellhead of the integrated filter water storage tank 6, and the rainwater will be filtered and purified again for storage and utilization. To provide the public areas with the water resources they need, and also to regulate and store the discharge pressure of the rainwater municipal pipe network.

Embodiments of the present utility model have been described above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative, rather than restrictive. Under the enlightenment of the utility model, personnel can also make many forms without departing from the scope of protection of the purpose of the utility model and claims, and these all belong to the protection of the utility model.
