Internal steel plate assembly type circular underground granary with prefabricated caulking strips

Abstract

The invention provides an internal steel plate assembly type circular underground granary with prefabricated caulking strips. The planar shape of the underground granary is circular, and the underground granary comprises multifunctional columns (1), multiple prefabricated granary wallboards (2), a granary roof (3), a granary bottom (4), and multiple fabricated caulking strips (5), wherein the granary wallboards (2) are prefabricated steel plate-concrete arc boards in the plane, the circumferences of the granary wallboards (2) are respectively connected with the multifunctional columns (1) and the prefabricated caulking strips (5) to form an integral cylinder structure; the multifunctional columns (1) locate the granary wallboards (2), the depth of each column anchoring into the earth is larger than the depth of the granary bottom (4), and the multifunctional columns (1) are main stress components for bearing the pressure of earth and the pressure of grains and resisting the floating force. The underground granary is characterized in that each multifunctional column (1) is divided into a plurality of sections from the top to the bottom, a first layer of granary wallboard is arranged on the inner side of the first section at the top layer, a second layer of granary wallboard is arranged on the inner side of the second section, and the granary wallboards are arranged in the same manner till the bottom layer of granary wallboard is also arranged, thereby forming the structure of the assembly type circular underground granary. The granary wallboards (2) are prefabricated composition boards formed by inner-side steel plates (9), ground anchors (10) and outer-side concrete (11), and the circumferences of the granary wallboards (2) are coated with steel plate seals.

Description

technical field [0001] The invention relates to the technical field of underground granaries, in particular to an assembled circular underground granary with prefabricated caulking strips. 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 and cohesive soil areas with low groundwater levels, such as cave warehouses, trumpet warehouses, double-curved arch warehouses, semi-underground warehouses, and cave-shaped trumpet warehouses; at the same time, most of the underground warehouses that have been built are made of bricks. Masonry structure, small storage 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. There are still some problems to be solved in the popularization and application of the above-mentioned new warehouse types, such as: (1) High standard waterproof and moisture-proof requirements for underground grain storage to ensure that the warehouse body does not leak or seep within the service life

The coiled material used at this stage is easy to age, the construction process is complicated and difficult, and it is prone to construction quality problems

(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] Prefabricated structures are 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. The quantity is large, which does not conform to the national sustainable development policy of energy conservation and environmental protection
