Description

Rainwater collection and utilization system for municipal engineering

Technical Field

The utility model belongs to the technical field of the technique of municipal construction and specifically relates to a rainwater collection utilizes system for municipal works is related to.

Background

With the acceleration of the urbanization process, some urban water resource shortage, water environment pollution, flood disasters, ecological environment deterioration and other problems in China are very serious. Rainwater is taken as a key element in a water circulation system and plays an important role in the process of constructing the urban sustainable water circulation system. Therefore, how to effectively collect and utilize the urban rainwater has become an important issue which needs to be paid attention to environment, municipal administration, planning, building, landscape, water conservancy and the like.

At present, urban rainwater is mainly drained into an urban underground water pipe network through drainage ditches on two sides of a road and finally converged into rivers, seas and lakes. However, since the urban rainwater usually carries some urban garbage and pollutants, the urban rainwater is directly discharged into rivers, seas and lakes to cause pollution pressure to the water environment; on the other hand, the effect of directly converging urban rainwater to rivers, seas and lakes is very limited, and the rainwater is not effectively utilized.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatic collect and filter the rainwater and can be applied to a rainwater collection and utilization system for municipal works that urban afforestation irrigated.

The utility model discloses a can realize through following technical scheme:

After more sundries are accumulated on the filter screen, the filter screen can be taken off from the inner side surface of the drainage brick for cleaning or replacement, and the drainage smoothness of the drainage ditch is kept.

Further setting the following steps: the longitudinal section of the drainage brick is in a trapezoid shape with a wide upper end and a narrow lower end, a first-stage rigid sieve plate is arranged on the cross section of the middle line of the drainage brick, and the shape and the size of the cross section of the middle line of the drainage brick are the same as those of the first-stage rigid sieve plate.

Through adopting above-mentioned technical scheme, set up one-level rigidity sieve on the cross section of drainage brick median line department, one-level rigidity sieve can filter the water that gets into in the escape canal before the filter screen, reduces the possibility that the filter screen is blockked up.

Further setting the following steps: the drainage brick is characterized in that an embedding strip is arranged at the middle line of the drainage brick, and the edges of two opposite sides of the first-stage rigid sieve plate are arranged on the embedding strip.

By adopting the technical scheme, the edges of the two opposite sides of the first-stage rigid sieve plate are placed on the embedding strips at the middle line of the drainage brick, so that the first-stage rigid sieve plate can be easily taken down from the drainage brick, and sundries on the first-stage rigid sieve plate can be conveniently cleaned.

Further setting the following steps: the top surface opening of sump pit just is equipped with second grade rigidity sieve.

Through adopting above-mentioned technical scheme, the top surface of sump pit sets up the second grade rigidity sieve, and the filterable rainwater permeable second grade rigidity sieve of process infiltration water layer gets into the sump pit, and during the grit that the second grade rigidity sieve prevented among the infiltration water layer got into the sump pit, it was still less to store up the grit in the sump pit.

Further setting the following steps: one side of the water collecting well is communicated with an inspection well, one end of the water pipe is connected with a water outlet of the water pump, and the other end of the water pipe penetrates through the inspection well and extends into a green belt on one side of the road.

Through adopting above-mentioned technical scheme, the water pipe passes the inspection shaft and extends to the greenbelt in, and municipal administration maintenance workman can get into the inspection shaft and overhauls water pipe and water pump, maintains for a long time.

Further setting the following steps: one end of the water pipe extending into the green belt is provided with a high-pressure spray head.

Through adopting above-mentioned technical scheme, set up high pressure nozzle on the water pipe, can enlarge irrigation scope, irrigate more evenly comprehensively.

To sum up, the utility model discloses a beneficial technological effect does:

(1) a water permeating layer and a water collecting well are arranged below the drainage ditch, rainwater collected into the drainage ditch can gradually penetrate through the water permeating layer to enter the water collecting well, most of garbage pollutants in the rainwater are retained in the drainage ditch and the water permeating layer, a water pump in the water collecting well pumps the collected rainwater into a green belt on one side of a road through a water pipe, irrigation on green plants on the road is achieved, the rainwater can be automatically filtered, collected and utilized, municipal construction cost is reduced, and the water collecting well is more environment-friendly;

(2) a filter screen is laid on the inner side surface of the drainage brick, a first-stage rigid sieve plate is arranged on the middle line of the drainage brick, rainwater and sewage enter a drainage ditch and are filtered twice through the first-stage rigid sieve plate and the filter screen, and then are filtered for the third time through a water seepage layer, so that the rainwater and sewage filtering effect is better, and a water seepage port of the drainage brick is not easy to block;

(3) dig at sump pit one side and establish the inspection shaft, the water pipe passes from the inspection shaft, makes things convenient for the municipal administration maintenance workman of later stage to overhaul water pipe and water pump.
