Step-like prefabrication assembly type round underground granary with steel plates wrapped internally and externally

Abstract

A prefabrication assembly type round underground granary comprises a granary bottom, a plurality of prefabricated granary wall plates, a granary top beam plate, multifunctional pillars and a plurality of layers of enhancing pillars, wherein the granary wall plates are arc prefabricated plates, and can be connected with the adjacent granary wall plates, the multifunctional pillars and the plurality of layers of enhancing pillars by means of connection devices; each multifunctional pillar is used for positioning a granary wall, and the depth of each multifunctional pillar anchored into soil is greater than the depth of a granary bottom plate; each multifunctional pillar is divided into a plurality of sections from top to bottom, the inner side of each first section on the uppermost layer is provided with a first-layer granary wall plate, one enhancing pillar is firstly arranged on the inner side of the corresponding second section, the inner side face of each enhancing pillar is enabled to be flush with the inner side face of the first-layer granary wall plate, then a second-layer granary wall plate is arranged on the inner side face of the corresponding enhancing pillar, and each first-layer granary wall plate and the corresponding second-layer granary wall plate are partially overlapped; by using an arrangement mode similar to that above, the second-layer granary wall plates and third-layer granary wall plates are partially overlapped, and overlapping is performed until the bottommost-layer granary wall plate is overlapped; the inner-side and outer-side steel plates and concrete therebetween are connected by adopting rivets.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to a ladder-shaped prefabricated circular underground granary both inside and outside covered with 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
