A kind of plastic module combination water pool
Affiliated technical field
The present invention relates to rainwater collects and a kind of water storage infiltration facility that utilizes.
Background technology
Collect rainwater, implementing soil infiltration is a kind of rainwater utilization mode commonly used.Facility commonly used is the steel concrete infiltration pond of the brick infiltration well or the side-wall hole of side-wall hole.Brick infiltration well, waste land resources, manually building by laying bricks or stones wastes time and energy.The infiltration pond of steel concrete is to be mixed by cement, stone, sand and water to stir, be cast in and be banded with the touching in the plate of cage of reinforcement, tear open to touch through the maintenance of certain hour and form, operation is various, and the construction period is long, the side-wall hole way has more increased the difficulty and the cost of construction, when removing for some reason, remove big, the discarded concrete block of difficulty in the pond, form building waste, contaminated environment.
Summary of the invention
In order to waste land resources from overcoming brick infiltration well and steel concrete infiltration pond, construction period is grown and abandons the pond and remove difficulty, the deficiency of building waste contaminated environment, the invention provides a kind of plastic module combination water pool, be assembled into the pond skeleton with plastic module, be used different clad materials, constitute plastic module combination water pool pond body, the pond can constitute the reservoir with simple function or have water storage concurrently and the infiltration pond of infiltration dual-use function.
The technical solution adopted for the present invention to solve the technical problems is: plastic module combination water pool, by pond, pond body, pond water inlet sand sediment trap, pond wet well, high and low position abat-vent, several parts such as pond water-in and water-out water pipe, pond bleed off pipe, pond aerating system are formed.The skeleton of pond, pond body is formed by the water storage module combinations of polypropylene plastics injection mo(u)lding.The plastic module monomer is cuboid, and the water-in and water-out interface tube of DN125 and DN150 is offered at the module two ends respectively, the inside modules hollow out, and void content reaches 95%, thereby has guaranteed that water can flow freely between module.The load pillar in the module and the Connection Card of module and intermodule make module and pond skeleton have enough supporting capacitys.Coat waterproofing geomembrane around the skeleton of pond, the pond has single water storage function; Wrap up permeable geotextiles pond around the skeleton and then have water storage and infiltration dual-use function concurrently.In pond water inlet sand sediment trap, realize the caliber conversion of rainwater pipe and pond water inlet pipe, help the deposition of silt.Establish a supply-water pump in the wet well of pond and supply water to the user, the pond is inner when needing to clean, and cooperates with the aerating system of being made up of air compressor and compressed air hose, has dashed the heavy mud at the bottom of the pond, and supply-water pump transforms dredge pump discharge body refuse water into.The air that high and low position abat-vent helps pond water surface upper space flows, and prevents that water quality of pond from worsening.
The invention has the beneficial effects as follows, be the reservoir of water cell with the plastic module, adopts assembling construction, convenient, fast; Detachable strange land is built or plastics recycling again; Change the clad material of pond skeleton, can make common reservoir or infiltration type reservoir.Present technique helps protecting land resources, and good economic benefit and social benefit are arranged.

The specific embodiment
In Fig. 1, the rainwater of collection is sent into pond water inlet sand sediment trap (2) with rainwater pipe (1), and in sand sediment trap, oarse-grained sedimentation is got off in the rainwater.Water inlet sand sediment trap (2) millpond water inlet pipe (4) links to each other with plastic module combination water pool pond body (6), into water threeway (3) is equipped with in pond water inlet pipe (4) end, the lower water inlet of threeway is established screen cloth (3-1), and the pond is full of the unnecessary rainwater in back and overflows from bleed off pipe (9).Water storage when the user supplies water, starts the supply-water pump of being located in the pond wet well (14) (15) with plastic module combination water pool, opens the valve (11) on the pressure water supply pipe (10), and at this moment, the blowoff valve (13) on the pond blow-off pipe (12) cuts out.When plastic module combination water pool is assembled into the use of infiltration pond, after the rainfall, flow into the rainwater in the pond, see through the permeable geotextiles (7-2) and side, the pond back-up sand layer (8-2) that are wrapped in the side, pond and in soil, permeate, self-restraint underground water.The valve (16) of pond outlet pipe (17) in the wet well of pond opened at ordinary times, closes when overhauling supply-water pump (15) or cleaning out well (14), prevents that the rainwater in the pond from pouring in the well.When inside, pond is cleaned, open air compressor (21) to compressed air hose (20) aerating system air feed, dashed the heavy mud at the bottom of the pond, body refuse water is imported in the wet well (14) by pond outlet pipe (17), open the supply-water pump (15) in the pond wet well (14), the blowoff valve of opening on the pond blow-off pipe (12) (13) is discharged body refuse water, and the valve (11) on pond feed pipe this moment (10) is closed.The air that low level abat-vent (5-1), high-order abat-vent (5-2) help pond water surface upper space flows, and prevents that water quality of pond from worsening.The sand bedding of pond top board (8-1) is used to keep the geotechnological performance of geotextiles, and the levelling layer of sand (8-3) of tank floor is used to guarantee that pond, pond body (6) is evenly stressed.Pond basal layer (18), soil rammed earth (19) are the general measures fixed by requirement of engineering.
