Description

A kind of stepped prefabricated assembled circular underground granary of encased steel plate
Technical field
The utility model is related to underground granary technical field, and in particular to a kind of stepped prefabricated assembled circle of encased steel plate Shape 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 generation, it is to avoid It is stifling using toxic agents, resist corollary failure and many merits such as dual-purpose of drawing, many experts are consistent with scholar to think reasonable Popularization and application underground grain storehouse new system and new technology, can realize low-temperature environment-friendly, energy-conservation save land, detraction of guaranteeing the quality, ecological grain storage.
The existing underground granary of China typically in the relatively low general loess of level of ground water and is adapted to being stained with property area, such as cave dwelling Storehouse, loudspeaker storehouse, double curvature arch storehouse, semi-underground bin, hole shape loudspeaker storehouse;Simultaneously built underground bin is generally brickwork construction, and capacity is small, accounts for Ground area is big, mechanization degree is low.
In order to build be useful in that level of ground water is higher, complex geological condition region can popularization and application Novel underground silo, Some national patents and document it is also proposed circular grain bin, and combined type is enclosed in the large space Underground Rectangular that cylinder, semicircular cylinder are surrounded, stake The storehouse such as underground bin type, but the popularization and application of above-mentioned new storehouse type, also in the presence of some problem demanding prompt solutions, such as:(1) underground grain storage Storehouse has high standard waterproof, moistureproof 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 trade environment construction period of deep basal pit It is long.After excavation of foundation pit, precipitation, orlop plate is cast-in-place, bulkhead slding form operation needs to be carried out in wet trade environmental condition for a long time, and work is strong Degree is big, long construction period, and construction cost is 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, steel plate can separately as the waterproof of bulkhead, damp-proof layer, also can bulkhead be connected to be formed with steel plate steel member The bulkhead of combining structure comes waterproof, protection against the tide.Underground granary bulkhead is shaped as linear or shaped form, such as cylindrical shape, square tube shape, Semicircle bulkhead etc..The invention solves the waterproof and dampproof problem of orlop plate by encased steel plate.Constructed in orlop simultaneously When, steel plate accelerates speed of application as template, reduces construction cost, but its construction is constructed for cast in situs, and the construction Method needs to carry out excavation of foundation pit, so there is the deficiencies such as integral constructing high cost, 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, and entirety is linked to be using connector between inwall and outer wall, and cavity is formed between inwall 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 such as construction trouble, the high, long construction period of construction cost.
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 is mainly using the traditional work mode of site operation, and industrialization degree is low, water consume, energy consumption, artificial rubbish, Quantity of wastewater effluent is big, does not meet the Sustainable development policies of national energy-saving and environmental protection.Using fabricated construction, can be pre- with factory System, assembled in situ, realize building structure industrialization, while material can be effectively improved in building energy conservation and the effect of structural behaviour Rate, energy saving and resource, reduce harmful effect, the limitation of reduction construction site of building waste and environment 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, researching and developing prefabricated assembled Novel underground storehouse has turned into required.

The outer surface of bulkhead plate 5 sprays mask coating, and the mask coating includes that the material of following weight portion is made:Stone 105 parts of oil asphalt, 13 parts of glass fibre, 10 parts of bentonite, 9 parts of emulsifying agent, 2.5 parts of dispersant, 2.5 parts of stabilizer, Organic fluoride 35 parts of modifying cinepazid emulsion, 3.5 parts of antifreeze.
The emulsifying agent uses hydrogenated tallow amine, the dispersant to use glyceryl monostearate, the stabilizer to use Sulfate, the antifreeze uses ethylene glycol.
Example IV to six provide the special mask coating in bulkhead plate outer surface, bulkhead plate is played protection, corrosion-resistant work With, antiseepage, sealing are played a part of to bulkhead, can be sprayed when bulkhead plate is prefabricated or be sprayed when assembling bulkhead at the scene, from The technical barriers such as the junction seepage of corner, gap, irregular structure are fundamentally solved, the water proofing property of underground granary is enhanced Energy.Glass fibre is added in mask coating, the toughness and tensile strength of coating is considerably increased, has delayed coating cracking Time, increase its service life, and also there is certain supporting role for bulkhead.The antifreezing agent of addition can reduce low temperature pair The damage of mask coating, it is ensured that the safe operation of cold district winter underground granary.
Finally illustrate, above example is only used to illustrate the technical solution of the utility model and unrestricted, this area Other modifications or equivalent that those of ordinary skill is made to the technical solution of the utility model, without departing from this practicality The spirit and scope of new technique scheme, all should cover in the middle of right of the present utility model.
