Application of soil hardener in wall body building of greenhouse

Abstract

The invention discloses application of a soil hardener in a wall body building of a greenhouse and prepared solidified soil. A preparation method of the soil hardener comprises the following steps of: dissolving 2.5 percent of hydroxypropyl methyl cellulose and 5 percent of polyacrylamide into 22.5 percent of water to form aqueous solution; adding 70 percent of water glass, uniformly stirring, adding 0.2 percent of curing agent basic solution into 99.8 percent of tap water with low salinity, and uniformly mixing to form hardener diluent; mixing 6 percent-8 percent of cement into 94 percent-92percent of plain soil to prepare mixing soil; uniformly spraying 12 percent of hardener diluent into 88 percent of mixing soil by several times, uniformly mixing, preparing to obtain the solidified soil, feeding into a walling die, uniformly paving on a working face, and dynamic consolidation compacting, wherein the maxim compacted density is 1.76g / cm<3>; and laminating and nourishing for 10-15 days, so that the soil hardener can come into use. The soil hardener in the wall body building of the greenhouse is suitable for the construction field of an aeolian sandy soil type wall body of a winter-warmed greenhouse, and has wide applicability.

Description

technical field [0001] The invention relates to a technical field of application of building materials; in particular, the invention relates to the technical field of specific application of a soil curing agent in the wall construction of a wind-warming type greenhouse in sandy soil. Background technique [0002] In recent years, all localities have attached great importance to the development of facility agriculture, and promoted facility agriculture as an effective measure to optimize the agricultural industrial structure, build modern agriculture, promote overall increase in agricultural production, effectively increase farmers' income, maintain social stability, and achieve an overall breakthrough in urban and rural planning. [0003] The development of facility agriculture internationally has a history of more than 100 years in Europe. The Netherlands is the birthplace of modern agriculture; real greenhouses only emerged in the 1950s, but large-scale modern facility agr...

Problems solved by technology

[0007] Although the reinforced concrete structure greenhouse has a service life of more than 30 years, its supporting functions, thermal insulation performance, protection level, labor intensity, wall compression resistance, etc. have been greatly improved and improved compared with civil structure greenhouses, but its high cost 300,000 to 400,000 / mu, which discourages farmers; on the other hand, the large amount of lime, cement, fly ash, crushed stone, gravel and other traditional wall building materials used in brick walls consumes resources and energy. Wasted land, destroyed vegetation, and emitted carbon dioxide and other greenhouse gases are all contrary to current energy conservation, emission reduction, and sustainable development policies and regulations

[0008] Steel structure greenhouses, aluminum alloy structure greenhouses and other material greenhouses, the cost of these high-end greenhouses is even more unacceptable to farmers, and the possibility of their promotion is obvious. The existing technology urgently needs a low-cost, reasonable structure, suitable for Characteristics of sandy soil types in Fengtarim Basin, Xinjiang and suitable building materials for the construction of existing winter warm greenhouses
