Description
Technical field
The invention belongs to Green Grain Storage technical field, be specifically related to a kind of Cang Ding and bulkhead is the underground granary pattern of the paraboloid of revolution。
Background technology
China has long using underground space to store the history of grain。After the founding of the state, underground granary construction be carry out prepare for war, an important component part of strategy and policy of preparing against natural disasters。Original underground bin is being investigated, is being excavated and on the basis of research, built the underground granary of various ways treatment in accordance with local conditions, but level of ground water lower ground district all built in by these silos, and be the less masonry structure of capacity or reinforced concrete structure by various places。The shortcoming that this kind of underground granary capacity is little, intensity is low, water resistance is not good significantly limit the promotion and application of large-scale low-temperature Green Grain Storage technology。In view of underground bin have occupation of land less, good concealment, airtight and temperature is low, stability of grain storage is good, saves the advantage such as the energy, developing a kind of large-scale green ecological grain storage new storehouse type with fine stress performance is the key issue technically solved at present。
Summary of the invention
For solving the problem that existing underground granary capacity is little, intensity is low, water resistance is not good, the present invention proposes a kind of new storehouse type, this storehouse type adopts paraboloid of revolution shape Cang Ding, ring beam, the compound mode of paraboloid of revolution shape bulkhead and Multi-functional vertical straight channel, in underground structure stress, storehouse body overall structure can be born bigger soil pressure and water pressure and meet maximum crack width and require to ensure not seep water, and single storehouse capacity is up to more than 2000t。In turnover grain, the paraboloid of revolution design of bulkhead itself can realize the gravity flow of grain, and the grain certainly flowed down can pass through the vertical transport equipment in Multi-functional vertical straight channel, it is achieved high efficiency operation of delivering from godown。
The technical solution adopted for the present invention to solve the technical problems is: the underground granary of a kind of paraboloid of revolution shape, including paraboloid of revolution shape Cang Ding, paraboloid of revolution shape bulkhead, ring beam, Multi-functional vertical straight channel, grain-entering mouth, conveying grain into storehouse shunting trousers pocket, vertical transport equipment, grain feelings detection equipment, Bulk Grain automobile, moving belt conveyer。Paraboloid of revolution shape storehouse is pushed up reasonable stress and water can be prevented to be detained for a long time at storehouse top surface, eliminates infiltration hidden danger；Paraboloid of revolution shape bulkhead not only reasonable stress, and the waterproof weak link at handing-over position at the bottom of tradition underground granary cylindrical shape bulkhead and storehouse can be avoided well, it is also possible to utilize the features of shape of himself to complete grain gravity flow；Ring beam, between bulkhead and storehouse push up, provides bigger hoop constraint to bulkhead and top edge position, storehouse, it is prevented that the excessive underground bin seepage problem caused in crack or crack occur；The Multi-functional vertical straight channel of circular cross-section is positioned at warehouse middle part, with bottom bulkhead, Cang Ding top and ground be connected, be used for inside it vertical transport equipment is installed；Being provided with Multifunctional mouth on multifunctional vertical conduit wall, Multifunctional mouth connects with warehouse grain storage layer, can be entered inside warehouse by Multifunctional mouth, it is achieved the ventilation of warehouse, artificial maintenance and plant maintenance；Conveying grain into storehouse shunting trousers pocket is arranged on multifunctional vertical channel roof, can fit into grain cause for gossip and now uniformly enter grain operation；Vertical transport equipment is used for lift grain, by vertical transport equipment, grain can be transported to ground place, it is achieved high efficiency grain delivers from godown operation；Grain feelings detection equipment is arranged on bulkhead inner surface, is used for monitoring grain storage grain feelings in storehouse, it is ensured that stored grain quality；Bulk Grain automobile and moving belt conveyer rest on the ground, and are conveying grain into storehouse and the significant levels transporting equipment delivered from godown。
The invention has the beneficial effects as follows: compared with traditional underground granary, the features such as underground grain storage new storehouse type has mechanization degree height, holding capacity of bin is big, storability good, version is simple for this, excellent in mechanical performance, be prone to anti-floating and water-proofing treatment, cost are low；Compared with the silo of ground, this whole warehouse of underground grain storing granary locates below ground level, and not only can ignore the impact of geological process, have good shock resistance, also have energy-conservation, save land, the feature of good concealment。Use underground granary to carry out bulk grain storage, be both beneficial to guarantee national food security, ensure economic construction, be conducive to again Green Grain Storage and health。Realizing intensive, the automatization of underground space grain storage, mechanization, containerization requirement, fully exploitation and the application underground space and superficial-layer geothermal energy, have important research and using value。
