Step-like prefabricated assembling type round underground barn externally clad with steel plates

Abstract

The invention provides a prefabricated assembling type underground barn. The plane shape of the underground barn is round; the underground barn comprises a barn bottom, a plurality of prefabricated barn wall plates, a barn top, a multifunctional column and a reinforcing column; the barn wall plates are arc-shaped prefabricated plate blocks and a connecting device is arranged at the periphery; the barn wall plates can be connected with the adjacent barn wall plate, the multifunctional column or the reinforcing column through the connecting device; the multifunctional column is used for positioning a barn wall; the depth of anchoring the multifunctional column into soil is greater than the depth of the barn bottom and the multifunctional column is a main stress component for bearing the soil pressure and the grain pressure and resisting buoyancy; the prefabricated assembling type round underground barn is characterized in that the multifunctional column is divided into a plurality of sections from top to bottom; a first-layer barn wall plate is arranged at the inner side of the first section of the uppermost layer; the reinforcing column is firstly arranged at the inner side of the second section so that the inner side face of the reinforcing column is leveled with the inner side face of the first-layer barn wall plate; a second-layer barn wall plate is arranged on the inner side face of the reinforcing column, so that the first-layer barn wall plate and the second-layer barn wall plate are partially overlapped; a similar setting manner is adopted so that the second-layer barn wall plate and a third-layer barn wall plate are partially overlapped until the barn wall plate on the bottommost layer is overlapped to form the step-like assembling type round underground barn.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to a stepped prefabricated and assembled circular underground granary 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 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
