Description

A stepped prefabricated rectangular underground granary covered with steel plates

technical field

The utility model relates to the technical field of underground granaries, in particular to a stepped prefabricated and assembled rectangular underground granary with outsourcing steel plates.

Background technique

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.

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 storage capacity, large floor space and low degree of mechanization.

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 urgently 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 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 work environment of deep foundation pit has a long construction period. After foundation pit excavation 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, resulting in high labor intensity, long construction period and high construction cost. (3) The cost of foundation pit support is high. For this kind of deep foundation pit, "steel pile + waist beam + water sealing steel plate" foundation pit support is a more economical way, but the cost accounts for 25-30% of the civil construction cost, and the construction cost is relatively high.

The invention whose application number is CN200910207155.1 discloses an underground granary, which includes a roof, a wall and a bottom. The steel plates are connected by steel members to form a combined structure of the warehouse wall to prevent water and moisture. The shape of the wall of the underground granary is straight or curved, such as cylindrical, square, semicircular, etc. The invention solves the waterproof and moisture-proof problem of the bottom plate of the warehouse through the outsourcing steel plate. At the same time, when the construction is carried out at the bottom of the warehouse, the steel plate is used as a formwork to speed up the construction and reduce the construction cost. However, the construction is pouring on site, and this construction method requires excavation of the foundation pit, so the overall construction cost is high and the construction period is long. insufficient.

The invention with application number CN200910207154.7 discloses an underground granary, including a roof, a wall and a bottom. The wall is divided into an inner wall and an outer wall. A cavity is formed between them, and the cavity is used for detection and repair of water leakage in the underground granary, and for ventilation of the underground granary and detection of grain conditions. The granary of the invention also needs foundation pit excavation, which has disadvantages such as troublesome construction, high construction cost, and long construction period.

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. The amount is large, which does not conform to the national sustainable development policy of energy conservation and environmental protection. The prefabricated structure can be prefabricated in the factory and assembled on site to realize the industrialization of building structures. At the same time, it can effectively improve the efficiency of materials in building energy saving and structural performance, save energy and resources, reduce construction waste and adverse effects on the environment, and reduce construction site restrictions. Wait. Therefore, in order to provide a "quick, good and economical" new type of underground grain storage, it has become necessary to develop a prefabricated new type of underground storage.
