Slot-type prefabricated assembly-type round underground granary clad with steel plates externally

Abstract

The invention discloses a prefabricated assembly-type underground granary, which comprises a granary bottom, prefabricated granary wall plates, a granary top and multifunctional columns, wherein the granary wall plates are arc-shaped prefabricated plate blocks; connecting devices are arranged on the peripheries of the granary wall plates; the granary wall plates can be connected with the adjacent granary wall plates and the multifunctional columns through the connecting devices; the multifunctional columns are used for locating a granary wall; the depths that the multifunctional columns are anchored into earth are more than the depth of the granary bottom; the multifunctional columns are main stress components for bearing the pressure of the earth and the lateral pressure of grains and resisting buoyant force. The prefabricated assembly-type underground granary is characterized in that the outer sides, the left ends and the right ends of the prefabricated granary wall plates are all clad with steel plates; further, the left ends of the prefabricated granary wall plates are provided with convex-type trapezoidal or semi-elliptical plugs; the right ends of the prefabricated granary wall plates are provided with concave-type trapezoidal or semi-elliptical slots; the multifunctional columns are divided into several sections from tops to bottoms; the inner sides of first sections of the uppermost layer are provided with a first layer of the granary wall plates; the inner sides of second sections are provided with a second layer of the granary wall plates; the granary wall plates are arranged until the bottommost layer of the granary wall plates by using a similar arrangement way, so as to form a round assembly-type underground granary structure.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to a prefabricated and assembled circular underground granary with slot-type outsourcing steel plates. 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.

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 qualit
