Abstract

The invention discloses a movable assembling type natural rainfall collection, storage and concentrated water supply system. The system comprises an underground water tank body, wherein a top cover is paved above the water tank body; the water tank body is made of a high-density polyethylene film and the top cover is in a multilayered composite structure including a bracket layer, a covering layer, a heat preservation layer, a soil layer and a ground layer in sequence from bottom to top; the top cover is internally provided with a water outlet pipeline penetrating the whole top cover to stretch into water of the water tank body. According to the movable assembling type natural rainfall collection, storage and concentrated water supply system, the high-density polyethylene film is creatively applied to the water tank body of the water supply system and can be buried into the ground for a long time, and no water dissolved-water substances are formed; a tank body can be naturally deformed and adapted along the deposition of a base groove after water is stored in the whole water tank body so that the service life of the system is prolonged; natural rainfall is sufficiently permeated into the water tank body by adopting the design of the top cover and the supporting strength is good.

Description

A kind of mobile assembling natural precipitation is collected, deposit, central water supply system

Technical field

The present invention relates to a kind of water system, particularly relate to be applicable to the poor arid area of western part of China can realize that natural precipitation is collected, deposit, central water supply system.

Background technology

In the similar area in China's western region or other countries, due to immiseration, the reason such as dry, large-area lack of water is a huge difficult problem in the local lives of the people all the time.Due to the social mobility in Chinese society's transitional period, in order to ensure necessary living water use, local women becomes the essential labour power in rural area, western poor arid area, they have to come and go every day several in, tens li of hill paths give life water for change.

For the problems referred to above, need on the one hand to strengthen local water supply project, but this needs huge economic input and long-term construction, not can realize in a short time; Need collection and the storage work of strengthening local natural precipitation on the other hand.For this reason, the All-China Women's Federation in 2000, Beijing Municipal Government, the Chinese Central Television (CCTV) sponsors, Chinese women's expansion funds can specifically be undertaken " be with one's heart at western share mother love " century, love took action large-scale public welfare activities, solicit contributions goodness-sum 1.16 hundred million yuan, for setting up " the liking mother's water cellar of the earth " project special fund, but, " mother's water cellar " this project to adopt be the most traditional mode of building underground tank by laying bricks or stones, it is large to there is labour intensity in this construction mode, a large amount of consumption highly energy-consuming material (portland cement), high cost and security reliability is poor, application life short the and consume material not drawback such as recoverable.

Specifically, portland cement water tank there will be material and spills in water the problem affecting water quality in Long-Time Service process, the more important thing is that long-term immersion can cause water slowly to penetrate cement, owing to permeating the existence of rear potential energy difference, oozing out of water can be more and more severe, causes finally losing use value; Simultaneously, traditional this structure design does not consider the problem how adding precipitation and collect completely, adopt open vinyl cover easily to cause a large amount of sewage to flow into or disposed waste inflow, adopt mudding lid that precipitation then can be caused to penetrate and cannot realize precipitation collecting function slowly.

Further, in long-term extension process, researcher finds the immovability due to this design tank body, cause its discarded rate high, easily occur discarding water tank along with many reasons such as building construction, resident's resettlement, village variations, cause huge economic waste.

Summary of the invention

Applicant is as the enterprise at building field long-term R & D, the needs in west area were fully taken into account in recent years in research process, creationaryly develop that a kind of removable fabricated natural precipitation is collected, deposit, central water supply system, this system not only effectively can realize collection and the storage of natural precipitation, and can assembling be moved, change the position of water system as required flexibly.

Specifically, the present invention is achieved through the following technical solutions:

A kind of mobile assembling natural precipitation is collected, deposit, central water supply system, comprises the water pot body being positioned at underground, above water pot body, is equipped with top cover; Wherein, water pot body is density polyethylene film with high material, top cover is multi-layer compound structure, bottom-uply be followed successively by shelf layer, covering layer, insulation layer, soil horizon and ground floor, have in top cover and run through whole top cover and be deep into outlet pipeline in water pot body water, the mouth of pipe place of outlet pipeline has pumping device.

Water storage container is made by adopting density polyethylene film with high (HDPE), can for a long time direct-burried in underground, material environment-protecting asepsis, without any water-soluble effluent, the more important thing is that HDPE material is pliable and tough, intensity is high, puncture-resistant, and after retaining, tank body can be out of shape adaptation naturally with foundation trench sedimentation, thus is applicable to the geographical environment of various harshness.The more important thing is, adopt the water pot body of HDPE material pliable and tough collapsible, lightweight (3kg/ cubic meter volume), can migrate with residence and move, and keep good application life (reaching more than 50 years), dead meal reproducible utilization.

According to the needs of design, above-mentioned water pot body section used is trapezoidal or rectangle, consider that maximizing precipitation collects, preferably trapezoidal, the grade of side slope that its side covers is 1:(0.5-1) (H/L, i.e. bottom width under the waist longitudinal projection on the longitudinally height/slope on slope).

Collecting to strengthen precipitation, can realize precipitation in Precipitation Process and can effectively enter water pot body, can preventing pollution thing and household garbage flow into again, and ensure effectively to form water pot body to cover, shelf layer is prefabricated reinforced concrete beam or wood purlin; Covering layer is precast concrete plate or reed matting cob; Insulation layer is straw insulation layer; Ground floor is for paving brick.

Said structure, has good support strength, and its structure can not form obstruct, even if also can ensure rapid osmotic when light rain to rainwater; The aperture of paving brick then effectively prevents pollutant and rubbish, and shelf layer then ensure that and effectively supports whole top cover; Insulation layer and tectal existence then have certain filter effect to precipitation.

When reality is constructed, top cover is opened the inflow that an open plate with suitable bore can ensure rainwater, closes this opening at ordinary times.

Although boiled use after normally utilizing pumping device to be extracted out by the water in water pot body in practice, but also having that some such as keep fowls, having a bath etc. uses the situation of unboiled water, in order to ensure the clean of water, between outlet pipeline to the mouth of pipe, strainer being installed.

Described strainer, can adopt the water filter that this area is common arbitrarily, such as active carbon water filter, millipore water strainer etc.

In order to strengthen fixed effect, water pot body opening part is fixedly connected with top cover by stud structure.

Above-mentioned stud structure can be cork, bolt etc.

Improved by said structure, water system hinge structure provided by the invention creates huge technological progress, fully ensure that collection and the storage of rainwater, and ensure that the application life of product.
