Inner and outer plastic wrapping prefabricated underground barn

Abstract

The invention provides an inner and outer plastic wrapping prefabricated underground barn. The inner and outer plastic wrapping prefabricated underground barn comprises a barn bottom, multiple prefabricated barn wallboards, a barn top and multifunctional columns. The barn wallboards are of overall structures formed by inner plastic plates, outer plastic plates and concrete plates between the inner plastic plates and the outer plastic plates, connecting devices are arranged on the peripheries of the barn wallboards, and the barn wallboards can be connected with the adjacent barn wallboards and the multifunctional columns through the connecting devices. The multifunctional columns are wrapped by plastic plates, the barn wallboards can be positioned, the depth of the portions, anchored into soil, of the multifunctional columns is larger than the depth of the barn bottom, and the multifunctional columns are main force bearing components for bearing soil pressure and grain side pressure and resisting buoyancy. The barn is characterized in that the multifunctional columns are divided into multiple segments from top to bottom, a first barn wallboard layer is arranged on the inner side of the first section of the uppermost layer, a second barn wallboard layer is arranged on the inner side of the second section till the lowest barn wallboard layer by means of the similar arrangement mode, and then the assembled underground barn structure is formed.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to a plastic prefabricated underground granary. Background technique [0002] Underground granaries are built under the shallow surface, which can store grain at low temperature all year round, maintain grain quality, inhibit the occurrence of pests, avoid fumigation with toxic chemicals, resist natural damage, and be used for both war and peace. Many experts and scholars agree that it is reasonable to promote the application of underground granaries The new system and new technology of grain storage can realize low-temperature environmental protection, energy saving and land saving, quality assurance and loss reduction, and ecological grain storage. [0003] The existing underground granaries in my country are generally located in general loess areas with low groundwater levels and suitable for sticky areas, such as cave warehouses, trumpet warehouses, double-curved a...

AI Technical Summary

Problems solved by technology

[0003] The existing underground granaries in my country are generally located in general loess areas with low groundwater levels and suitable for sticky areas, such as cave warehouses, trumpet warehouses, double-curved arch warehouses, semi-underground warehouses, and cave-shaped trumpet warehouses; Brick structure, small warehouse capacity, large floor area and low degree of mechanization

[0004] In order to build a new type of underground granary that can be popularized and applied in areas with high groundwater levels and complex geological conditions, some national patents and documents have also proposed a circular granary, a large underground rectangle surrounded by cylinders and semi-cylinders, and a pile-enclosed compound type. However, there are still some problems to be solved in the popularization and application of the above-mentioned new warehouse types, such as: (1) Underground grain storage warehouses have high standards of waterproof and moisture-proof requirements

Ensure that the warehouse body does not leak or seep water within the service life; the coiled material used is easy to age, the construction process is complex and difficult, and construction qua...
