The construction method has important practical value in promoting the rain water collection, storage and utilization technology development in areas which lack water resources, in particular dry and semi-dry areas.
Description
Technical field
The invention belongs to drought-hit area agricultural life, production and improvement of the ecological environment water saving, retaining and water conservation technical field, relate generally to the material and technology of building water storage facilities, particularly a kind of method of utilizing soil curing material to build water storage facilities, this method is applicable to the storing facilities of water in rural area, handles as antiseepages such as water cellar, water kiln, pond, fish pond, dykes.
Background technology
China is a drought and water shortage country, water resources ownership per capita 2200m
3, only be world occupancy volume per person's 1/4, now still have 2.5 hundred million people's dysdipsias, account for 20% of country's total population, wherein part population is positioned at bitter inferior area, and the rainwater that utilizes water cellar to collect is important water source; About 1,100,000,000 mu of China's nonirrigated farmland area accounts for about 60% of China's cultivated area, and no irrigating facility and water condition can only rely on the natural rainfall resource to keep plant growth.The essential measure of realizing dry farming field-crop high yield, stable yields is utilization rate and the utilization ratio that how effectively to improve the natural rainfall resource.Facts have proved that collection rain supplement irrigation agricultural is to realize the effective way of above-mentioned target.Moreover, China is owing to influenced by monsoon climate, and rainfall undue concentration, and spatial and temporal distributions inequality make rainfall and crop need the water asynchronism(-nization) step, cause long-term arid and seasonal drought serious.Theory and practice proves that rainwater collection storage utilization technology is to solve water resource to lack the especially effective way of arid and semi-arid area people's productive life water of area.Storing facilities of water such as water cellar are the important contents of this technical system, also are one of its key technologies.At present, build water cellar material red clay, cement mortar, concrete or the Polypropylence Sheets etc. of adopting more.Red clay has good barrier performance and water quality preferably, but material is difficult to obtain, and construction technology is very loaded down with trivial details, does not adopt substantially at present; Cement mortar and concrete material have favorable durability and barrier performance, the at present employing more, but owing to reasons such as raw-material shortage such as sandstone make cost comparatively expensive, and water quality constantly is under suspicion; The coating materials anti-seepage effect is better, but durability is relatively poor.The shortcoming of these materials has greatly limited the development and the utilization of rainwater collection storage utilization technology.Therefore, seek a kind of economy, efficient, environmental protection, and the novel storing facilities of water material of being convenient to construct and construction technology thereof are problem demanding prompt solutions always.
Summary of the invention
