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

Abstract

A prefabrication assembly type underground granary comprises a granary bottom, a plurality of prefabricated granary wall plates, a granary top, multifunctional pillars and a plurality of layers of enhancing pillars, wherein each granary wall plate is of an integral structure formed by combining a plastic plate on the inner side and a concrete slab on the outer side, the granary wall plates are provided with connection devices on the peripheries, and can be connected with the adjacent granary wall plates, the multifunctional pillars and the plurality of layers of enhancing pillars by means of the connection devices; the multifunctional pillars can be used for positioning the granary wall plates, and are main stress components for bearing soil pressure and grain side pressure and resisting buoyance, and the depth of each multifunctional pillar anchored into soil is deeper than the depth of the granary bottom; the underground granary is characterized in that 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, the corresponding enhancing pillars are firstly arranged on the inner side of the corresponding second section, the inner side faces of the enhancing pillars are 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 the first-layer granary wall plate and the second-layer granary wall plate are partially overlapped; by using an arrangement mode similar to that above, each second-layer granary wall plate and a third-layer granary wall plate are partially overlapped, and overlapping is performed until the bottommost-layer granary wall plate is overlapped, thus forming the step-like assembly type underground granary.
