The purpose of this utility model, the lateral pressure resistant tightness barn structure technology that be to provide a kind of and can solve above deficiency of the prior art, is applicable to use in newly-built silo and existing old storehouse transformation and upgrade, construction/improvement cost is lower simultaneously.
The concrete technical scheme of the utility model lateral pressure resistant tightness silo is as follows: in silo furred ceiling bottom surface, be provided with polyurethane coating foaming layer; On silo interior wall, from main body wall toward in, be followed successively by polyurethane coating foaming layer, the steel screen layer that is filled with mortar and putty surface layer; On described silo interior wall and the polyurethane coating foaming layer of laying under furred ceiling be connected as a single entity; The aperture of described gauze wire cloth is 10mm * 10mm～40mm * 40mm, and gauge of wire used is Φ 1.0mm～Φ 2.0mm; Described mortar adopts environmental protection mortar, and thickness is 5mm～15mm;
Silo terrace surface is followed successively by plain soil layer, cement stabilized macadam stabilized zone, high strength elastic sealing coiled material layer and concrete layer from the bottom to top; And described high strength elastic sealing coiled material layer is provided with U-shaped flanging at terrace and silo interior wall joint.
Wherein, the polyurethane coating depth of foam that is positioned at described silo furred ceiling bottom surface is preferably 20mm～80mm; Polyurethane coating depth of foam on described silo interior wall is preferably 10mm～50mm; The thickness of the polyurethane coating foaming layer of described silo furred ceiling and silo interior wall lap-joint is not less than 100mm; The density of the polyurethane coating foaming layer on described silo interior wall should be not less than 55kg/m
3.The polyurethane coating foaming layer that is positioned at wall corner preferably adopts arc-shaped transition.
Facts have proved: after adopting the technical scheme of the utility model lateral pressure resistant tightness silo to undergo technological transformation to silo interior wall, furred ceiling and ground, silo tightness and wall lateral pressure resistant power are significantly improved, there is heat preservation and insulation moisture proof and anti-condensation performance simultaneously, can meet low temperature or the controlled atmosphere Green Grain Storage high request to whole tightness raising in silo wall lateral pressure resistant power, storehouse completely.Relevant test data shows: when test pressure is from-drop to-150pa of 300pa, the pressure half-life is greater than 300s, shows that silo tightness meets the requirements completely, and thermal insulation humidity resistance is good; Meanwhile, the lateral pressure that ground and silo interior wall can carry the high Bulk Grain of 8-10m.The technical scheme of the utility model lateral pressure resistant tightness silo can be used in newly-built silo and the transformation and upgrade of old storehouse, there is the low and low advantage of difficulty of construction of cost, contribute to improve grain depot grain storage ability, reduce grain storage cost, be specially adapted to modernization high request silo as the construction of large storehouse, silo, to advancing modernization green energy conservation grain storage technology and grain security significant.
