Description
Technical field
The present invention relates to underground granary technical fields, and in particular to a kind of bilayer assembled underground granary.
Background technology
Underground granary is built under shallow layer surface, long-term low-temperature grain-storage, is kept grain quality, is inhibited insect pest, avoids
It is stifling using toxic agents, corollary failure and dual-purpose equal many merits of drawing are resisted, 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 lower general loess of level of ground water and is suitble 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 simultaneously is mostly brickwork construction, and capacity is small, accounts for
Ground area is big, mechanization degree is low.
It is useful in the Novel underground silo that level of ground water is higher, complex geological condition region can promote and apply in order to build,
Some national patents and document also proposed circular grain bin, the large space Underground Rectangular that cylinder, semicircular cylinder surround, and combined type is enclosed in stake
The storehouses such as underground bin type, but the popularization and application of above-mentioned new storehouse type, there is also 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, is susceptible to construction quality problem.(2) the wet construction 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 carry out in wet construction environmental condition for a long time, and labour is strong
Big, long construction period is spent, 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.
Application No. is a kind of underground granary of the disclosure of the invention of 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 connect to be formed with steel member with steel plate
The bulkhead of composite structure carrys out waterproof, moisture-proof.The shape of underground granary bulkhead be linear or curved shape, as cylindrical shape, square tube shape,
Semicircle bulkhead etc..The invention solves the problems, such as the waterproof and dampproof of orlop plate by encased steel plate.It constructs simultaneously in orlop
When, steel plate accelerates speed of application as template, reduces construction cost, but its construction, which is cast in situs, constructs, and the construction
The deficiencies of method needs to carry out excavation of foundation pit, and it is of high cost to there is integral constructing in this way, long construction period.
Application No. is a kind of underground granary of the disclosure of the invention of 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, forms cavity 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
It is also required to excavation of foundation pit, 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 the Sustainable development policies of national energy-saving and environmental protection.It, can be pre- with factory using fabricated construction
System, assembled in situ, realize building structure industrialization, while can effectively improve material building energy conservation and structural behaviour effect
Rate, energy saving and resource, reduce the harmful effect of building waste and environment, reduce 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 have become it is required.

When siding, height is excavated first and is greater than or equal to prefabricated bulkhead plate height, diameter is greater than or equal to the space of warehouse overall diameter, together
When ensure that the soil body does not cave in digging process, could giving prefabricated bulkhead plate to install in this way, there are construction space, guarantee bulkhead plates
Construction safety is smoothed out；When cutting depth is below level of ground water, precipitation is first carried out, is then excavated；It installs
After every layer of prefabricated bulkhead plate, the slip casting between bulkhead surrounding soil and prefabricated bulkhead plate ensures when excavating next layer soil body, this
Layer soil body does not cave in, safety when to ensure that subsoil excavates.
When every layer of prefabricated bulkhead plate installation, outer bulkhead plate is welded to connect with adjacent multiple function first, ensures prefabricated storehouse
Siding is reliably connected with multiple function, is then welded to connect inner barn wall plate and adjacent multiple function, and water is welded with junction steel plate
Put down adjacent inner barn wall plate, finally poured in the cavity that multiple function, contiguous prefabricated inner barn wall plate and junction steel plate surround with
Prefabricated inner barn wall plate is identical or the water-proof concrete of a high strength grade.
Adjacent level prefabricated bulkhead plate in left and right carries out the installation of neighbouring vertical prefabricated outer bulkhead plate after installing：First
By the prefabricated chunk of inner barn wall vertical outboard alignment up and down, then with junction steel plate on the outside, inside welding it is adjacent prefabricated up and down
Plate finally pours identical as prefabricated bulkhead plate on the outside, in the cavity that surrounds of inside junction steel plate and contiguous prefabricated plate
Or the water-proof concrete of a high strength grade.Neighbouring vertical prefabricated outer bulkhead plate carries out neighbouring vertical after installing
The installation of prefabricated inner barn wall plate：First by the prefabricated chunk of outer bulkhead vertical outboard alignment up and down, then with junction steel plate on the outside,
The adjacent prefabricated chunk up and down of inside welding, finally on the outside, in the cavity that surrounds of inside junction steel plate and contiguous prefabricated plate
Pour the water-proof concrete of identical as a prefabricated bulkhead plate or high strength grade.By above-mentioned construction method, open successively from top to bottom
Excavator body and the prefabricated bulkhead plate of installation, the cylinder warehouse structure that every layer of bulkhead plate is formed can be used as foundation pit supporting system, in this way, very
Silo warehouse structure is combined into one with foundation pit supporting system well, not only saved caused by independent progress pattern foundation pit supporting structure at
This, substantially reduces construction investment, and substantially reduce the construction period of entire engineering.
