Description
Technical field
The present invention relates to underground granary technical field, and in particular to a kind of interior stepped prefabricated assembled rectangle of encased steel plate
Underground granary.
Background technology
Underground granary is built under shallow layer surface, long-term low-temperature grain-storage, is kept grain quality, is suppressed insect pest, avoids
Fumigated using toxic agents, resistance corollary failure and many merits such as dual-purpose of drawing, many experts are consistent with scholar to think reasonable
Promote and apply underground grain storehouse new system and new technology, can realize low-temperature environment-friendly, it is energy saving save land, detraction of guaranteeing the quality, ecological grain storage.
The existing underground granary in China generally in the relatively low general loess of level of ground water and is adapted to being stained with property regional, such as cave dwelling
Storehouse, loudspeaker storehouse, double curvature arch storehouse, semi-underground bin, hole shape loudspeaker storehouse；Underground bin built at the same time is mostly brickwork construction, and capacity is small, accounts for
Ground area is big, mechanization degree is low.
The Novel underground silo that level of ground water is higher, complex geological condition region can promote and apply is useful in order to build,
Some national patents and document it is also proposed circular grain bin, the large space Underground Rectangular that cylinder, semicircular cylinder surround, and combined type is enclosed in stake
The storehouse such as underground bin type, but the popularization and application of above-mentioned new storehouse type, also there are some urgent problems to be solved, such as：(1) underground grain storage
Storehouse has high standard waterproof, moisture-proof requirement.Ensure that warehouse is water-tight within service life, it is impermeable；The web material of use is easy
Aging, working procedure is complicated, and difficulty is big, construction quality problem easily occurs.(2) the wet construction environment construction period of deep basal pit
It is long.After excavation of foundation pit, precipitation, orlop is cast-in-place, bulkhead slding form operation needs to carry out in wet construction environmental condition for a long time, labor intensity
Greatly, long construction period, construction cost are high.(3) pattern foundation pit supporting structure is costly.For such deep basal pit, " piling bar+waist rail+water shutoff steel
Plate " pattern foundation pit supporting structure is relatively inexpensive mode, but expense accounts for the 25-30% of civil engineering construction cost, and construction cost is higher.
A kind of underground granary of the disclosure of the invention of Application No. CN200910207155.1, including silo roof, bulkhead and orlop,
The bulkhead Covered with Angles, waterproof that steel plate can be separately as bulkhead, damp-proof layer, also can bulkhead be connected to be formed with steel member with steel plate
The bulkhead of combining structure carrys out waterproof, moisture-proof.The shape of underground granary bulkhead is linear or shaped form, as cylindrical shape, square tube shape,
Semicircle bulkhead etc..The invention solves the problems, such as the waterproof and dampproof of orlop by encased steel plate.At the same time when orlop is constructed,
Steel plate is as template, and quickening speed of application, reduces construction cost, but its construction is constructed for cast in situs, and the construction party
The deficiencies of method needs to carry out excavation of foundation pit, so of high cost there are integral constructing, long construction period.
A kind of underground granary of the disclosure of the invention of Application No. CN200910207154.7, including silo roof, bulkhead and orlop,
The bulkhead is divided into inner and outer wall, is linked to be entirety using connector between inner wall and outer wall, cavity is formed between inner wall and outer wall,
The cavity is used for the detection and reparation of underground granary leak, and for underground granary ventilation and the detection of grain feelings.The invention silo
Excavation of foundation pit is also required to, there is the deficiencies of high construction trouble, construction cost, long construction period.
Prefabricated construction is one of the effective way for realizing building structure industrialization and building energy conservation section row, for a long time with
Come, concrete construction mainly use site operation traditional work mode, industrialization degree is low, water consume, energy consumption, artificial rubbish,
Quantity of wastewater effluent is big, does not meet national energy-saving and the Sustainable development policies of environmental protection., can be pre- with factory using fabricated construction
System, assembled in situ, realize building structure industrialization, while can effectively improve material in building energy conservation and the effect of structural behaviour
Rate, save the energy and resource, reduces the harmful effect of building waste and environment, reduces construction site limitation etc..Therefore, in order to carry
For it is a kind of " it is fast, good, save " the new storehouse type of underground grain storage, research and develop prefabricated assembled Novel underground storehouse has become required.
The content of the invention
It is an object of the invention to provide a kind of interior stepped prefabricated assembled rectangular underground granary of encased steel plate, this is prefabricated
Assembled underground granary can replace waterproof roll and prefabricated bulkhead plate outer reinforcement using encased steel plate, with preferable waterproof,
Anti-seepage effect and comprehensive benefit；Prefabricated bulkhead plate can be produced in prefabricated components factory normalization, and processing and manufacturing quality can be effective
Control again energy conservation and environmental protection, Prefabricated Assembling, mechanization installation, can crossed construction, shorten the construction period.In addition,
Prefabricated warehouse structure can be used as foundation pit supporting system, save pattern foundation pit supporting structure cost, reduce construction investment.
The present invention solution be：A kind of prefabricated assembled underground granary, the flat shape of the underground granary is rectangle,
Including orlop, the prefabricated bulkhead plate of polylith, silo roof, multiple function, reinforcing prop, the prefabricated bulkhead plate is rectangle prefabricated chunk,

Example IV provides the special mask coating in prefabricated bulkhead plate outer surface to six, prefabricated bulkhead plate is played protection,
Corrosion-resistant acts on, and plays the role of antiseepage, sealing to bulkhead, can spray when prefabricated bulkhead plate is prefabricated or assemble storehouse at the scene
Sprayed during wall, fundamentally solve corner, gap, irregular structure junction leakage etc. technical barrier, enhance underground
The water resistance of silo.Glass fibre is added in mask coating, the toughness and tensile strength of coating is considerably increased, delays
The time of coating cracking, increase its service life, and also there is certain supporting role for bulkhead.The antifreezing agent of addition can
To reduce damage of the low temperature to mask coating, the safe operation of cold district winter underground granary ensure that.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff makes technical scheme, without departing from technical solution of the present invention
Spirit and scope, should all cover among scope of the presently claimed invention.
