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.

Between, while ensureing that the soil body does not cave in digging process, could giving prefabricated bulkhead plate installation in this way, there are construction spaces, ensure pre-
Bulkhead plate construction safety processed is smoothed out;When cutting depth is below level of ground water, precipitation is first carried out, is then opened
It digs;After installing every layer of prefabricated bulkhead plate, the slip casting between bulkhead surrounding soil and prefabricated bulkhead plate, in this way, the soil body, slurry and
Prefabricated bulkhead plate forms a closely knit entirety, ensures that this layer soil body does not cave in when excavating next layer soil body, under ensureing
Safety when layer soil excavates.When every layer of prefabricated bulkhead plate installation, first by prefabricated bulkhead plate and adjacent multiple function or reinforcing prop
Welding, ensures that prefabricated bulkhead plate is reliably connected with multiple function or reinforcing prop, then uses junction steel plate weld horizontal contiguous prefabricated
Bulkhead plate;After the prefabricated bulkhead plate installation of adjacent upper layer and lower layer is in place, first with the neighbouring bulkhead of elongated fillet weld seam, then edge
Weld seam circumferential direction installs ribbed stiffener, finally installs oblique stiffening plate;After neighbouring bulkhead construction, in horizontally adjacent prefabricated storehouse
Siding pours the water-proof concrete with prefabricated bulkhead plate ad eundem.By this construction method, the soil body and peace are excavated successively from top to bottom
Prefabricated bulkhead plate is filled, the cylinder warehouse structure that every layer of prefabricated bulkhead plate is formed can be used as foundation pit supporting system, in this way, well will
Silo warehouse structure is combined into one with foundation pit supporting system, has not only saved cost caused by independent progress pattern foundation pit supporting structure, greatly
It is big to reduce construction investment, and substantially reduce the construction period of entire engineering.

Corrosion-resistant acts on, and plays the role of antiseepage, sealing to bulkhead, can spray when prefabricated bulkhead plate is prefabricated or organize at the scene binning
Sprayed when wall, fundamentally solve corner, gap, irregular structure junction leakage etc. technical barriers, 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 increases its service life, and also has 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 examples are only used to illustrate the technical scheme of the present invention and are not limiting, this field is common
Other modifications or equivalent replacement that technical staff makes technical scheme of the present invention, without departing from technical solution of the present invention
Spirit and scope, be intended to be within the scope of the claims of the invention.
