Description

A kind of storm water management system

Technical field

The utility model relates to the rainwater utilization technical field, particularly a kind of storm water management system.

Background technology

At present, prior art provides rainwater utilization to be: build a little open-air other escape canals of rainwater collecting pit, highway and the storm sewer exhaust system of building class at the concrete of using that is to use.The rainwater that this old-fashioned traditional mode is collected is evaporated very soon, and water quality is also poor, and not environmental protection can not be filtered into clean rainwater and replenish groundwater resources then.Do not subtract the effect of flood, environment protection emission yet.Open open-air collecting pit and escape canal easily frequently cause dangerous accident, also are the hotbeds of insect and carrier, and easily producing has the worm of falling ill, and jeopardizes human health, except the health and safety problem, does not have the effect of rainwater catchment system basically.Also take a large amount of land areas.The city is had the problem of a negative effect.

Traditional construction drainage mode is that rainwater and sanitary sewage are flowed into Wastewater Treatment Plant or directly enter the river through the pipe drainage system, has not only polluted the river, has also polluted the environment and the face of land and underground water.Also surrounding air is polluted simultaneously.These traditional mode construction durations are long, process is loaded down with trivial details, cost is high, also be unfavorable for large-scale application.

Traditional civil engineering rainwater collecting pit reinforcing bar mixes the defective of earth: 1: from great; 2: crack resistance is poor, once the cracking pond is meaningless; 3: bearing capacity is limited; 4: construction is complicated, operation many (formworks, tie up reinforcing bar, build, maintenance etc.), 5: long in time limit; Construction is subjected to the influence of season, weather bigger; In a single day concrete structure destroys, and its reparation, reinforcing, reinforcement be difficulty relatively.Bulk life time 12 years, the life-span is shorter.

Wherein, preferably, the below of the described first rainwater matrix also is provided with second raintank, and described second raintank and first raintank all are wrapped in described infiltration geotextiles the inside simultaneously, be equiped with water level sensor in described second raintank, an end of water pump inserts described second raintank.

Wherein, preferred, the other end of described water pump is connected with irrigation rig.

Wherein, preferred, also be equiped with the fine sand layer between the infiltration geotextiles of this first rainwater matrix and second raintank and the described antiseepage plastic membranous layer.

Wherein, preferred, described second raintank also is communicated with the second rainwater matrix by pipeline, and the described second rainwater matrix comprises first raintank composition, and the described second rainwater matrix is permeated geotextiles or wrapped up by the antiseepage plastic membranous layer.

Wherein, preferred, described first and second raintank all are by an assembled rectangular box of polylith plastic plate.

Wherein, preferred, described second band drain is cellular.

By implementing above technical scheme, have following technique effect: this storm water management system is by collection, infiltration, delay, overanxious rainwater; Can flood control and disaster reduction, erosion and deposition control; The aquifer recharge of drinking water supply and safety is protected water resource; Make land reclamation, increase the value in soil; Reduction is to the dependence of tap water; Rainwater matrix norm blocking structure design, low maintenance degree reduce, and install fasterly, safer, more convenient, and cost is cheaper.

Description of drawings

The structural representation of the storm water management system that Fig. 1 provides for the utility model;

The structural representation of the first rainwater matrix that first raintank that Fig. 2 provides for the utility model embodiment is formed.

The specific embodiment

In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model provides a kind of storm water management system, as shown in Figure 1, comprise: the dmp filter well 3 that inserts sewer pipe 2, this sewer pipe 2 is switched to first band drain 1 of roof, described dmp filter well 3 is switched in second band drain 5, described second band drain, 5 coated outside have infiltration geotextiles 4, the below of described second band drain 5 is provided with collecting pit, described collecting pit coated outside has the antiseepage plastic membranous layer, be equiped with the first rainwater matrix of first raintank, 11 compositions of a plurality of modulars in the described collecting pit, the external surface of the described first rainwater matrix is enclosed with infiltration geotextiles 4.Rainwater through roofing or surface soil 6 penetrate in the band drain 1, can be with dmp filter before entering band drain 1 through soil and river sand; Rainwater is entered in the dmp filter well 3 by sewer pipe 2 and filters once more, enters then by in the band drain 5 of infiltration geotextiles 4 parcels; This moment, the rainwater in the band drain 5 was again through pipeline or directly be penetrated in the whole collecting pit that is surrounded by antiseepage plastic membranous layer 12, the first rainwater matrix that first raintank 11 of the modular in collecting pit is formed is by infiltrative geotextiles 4 environmental sealings of tool, and the rainwater that infiltration is come in the space that the first rainwater matrix forms is stored.
