A prefabricated circular underground granary with outsourcing steel plate

Abstract

A steel plate-clad prefabricated circular underground granary that is circular in plane shape and comprises a bottom, a plurality of prefabricated wall plates, a roof and a multifunctional column; the wall plates are arc prefabricated plates, connectors are arranged around each arc prefabricated plate, and one wall plate can be connected with the adjacent wall plate and the multifunctional column through the corresponding connectors; the multifunctional column can position a granary wall, depth of the multifunctional column anchored in soil is greater than bottom depth of the granary, and the multifunctional column is a main bearing member for bearing soil pressure, cereal pressure and resistive floating force; the granary is characterized in that the multifunctional column includes multiple segments from top to bottom, the uppermost first segment is provided with a first wall plate layer on the inner side, the second segment is provided with a second wall plate layer on the inner side, and the similar arrangement is carried out until the lowest wall plate layer to form the prefabricated circular underground granary; the prefabricated wall plates are of integrated structure formed by combining an outer steel plate and an inner concrete plate, the outer steel plate and the inner concrete plate are connected through anchors, and both the left and right ends of each prefabricated wall plate are clad with U-shaped steel plates.

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 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 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
