Insertion groove type underground barn with internally covered plastics and prefabricated barn wall

Abstract

The invention relates to a prefabricated and assembled underground barn, which comprises a barn bottom, a plurality of prefabricated barn wall plates, a barn roof and multifunctional columns, wherein each barn wall plate is of an integral structure formed by combining a plastic plate arranged at the inner side and a concrete plate arranged at the outer side; connecting devices are arranged on the periphery; through the connecting devices, the barn wall plates can be connected with the adjacent barn wall plates and the multifunctional columns; the multifunctional columns can be used for positioning the barn wall plates; the soil entering depth of the multifunctional columns is greater than the depth of the barn bottom; the multifunctional columns are major stress components for bearing soil pressure and grain lateral pressure and resisting the buoyancy force. The prefabricated and assembled underground barn is characterized in that the multifunctional columns are separated into a plurality of sections from top to bottom; a first layer of barn wall plate is arranged at the inner side of the first section at the uppermost layer; and a second layer of barn wall plate is arranged at the inner side of the second section; the similar setting mode is used till the lowermost layer of barn wall plate is reached; an assembled underground barn structure is formed; steel plates are covered on the left end part and the right end part of the prefabricated barn plates; the left end of the prefabricated barn plates is provided with a convex trapezoidal or semicircular plug; and the right end of the prefabricated barn plates is provided with a concave trapezoidal or semicircular insertion groove.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to a slot-type underground granary with inner plastic prefabricated walls. 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 ...

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 quality problems are prone to occur

(2) The wet working environment of deep foundation pit has a long construction period

After the excavation of the foundation pit and precipitation, the cast-in-place construction of the warehouse floor and the sliding form construction of the warehouse wall need to be carried out in a wet working environment for a long time, which has high labor intensity, long construction period and high construction cost

(3) The cost of foundation pit support is high

The granary of this invention also requires foundation pit excavation, which has disadvantages such as troublesome construction, high construction cost, and long construction period.

[0007] The prefabricated structure is one of the effective ways to realize the industrialization of building structures and building energy saving and emission reduction. For a long time, concrete buildings mainly adopt the traditional operation method of on-site construction, with a low degree of industrialization, water consumption, energy consumption, artificial waste, and sewage discharge. A large amount does not conform to the national sustainable development policy of energy conservation and environmental protection
