Description
Technical field
The utility model relates to a kind of oil tank soil protection body, is specifically related to a kind of oil tank reinforced earth protection body and construction method thereof.
Background technology
The oil storage of earthing oil tank is one of important way of world front oil strategic reserves.The construction program of earthing oil tank, normally first excavates out certain space downwards on level land or hillside, builds up oil tank, and then build tank room revetment by laying bricks or stones, and cast watch box vault, waits and assemble tank accessories, finally remake earthing process.
China's earthing construction requirement tank room vault thickness of earth covering should be no less than 0.5m, and the earthing width on enclosure wall top is generally not less than 1.5m, and the earthing gradient is not less than 1:1.5.Tradition earthing directly piles up the earthwork around oil tank, and the capacity of earthing oil tank is generally 1000-10000m
3, bulky, be difficult to after earthing to certain altitude continue upper soil and machinery compacting cannot be adopted, structural instability.This earthing method exists takes up an area greatly, and earth volume is large, does not cover the problems such as soil, be difficult to meet earthing standard-required, and earthing is easily washed away by rainwater, needs every year to drop into a large amount of maintenance costs, wastes time and energy.
Utility model content
For making up the deficiencies in the prior art, the utility model provides one to save the area, and reduces earth volume, can greening and environmental protection, camouflage, cost low and there is oil tank reinforced earth protection body and the construction method thereof of stronger anti-seismic performance.
The utility model is achieved by the following technical solution:
A kind of oil tank reinforced earth protection body, comprise ground and reinforced earth protection body, its special character is: described reinforced earth protection body adopts geogrids layer and packing layer to replace pressing and forms, oil tank surrounding adopts unidirectional geo-grid, adopt pitman and last layer to carry out tension outside the unidirectional geo-grid of lower one deck to be connected, pile up mount compacting inside the unidirectional geo-grid of lower one deck, and compress the unidirectional geo-grid of last layer.
Oil tank reinforced earth protection body of the present utility model, Qiang Wai side, described reinforced earth protection body lateral is enclosed with turf.
Oil tank reinforced earth protection body of the present utility model, roof adopts one to two layer of direction earthwork grille, and in direction earthwork grille, layering is filled with filler, and the superiors are paved with turf or grass-seed.
Oil tank reinforced earth protection body of the present utility model, described ground comprises some layers of direction earthwork grille, and in direction earthwork grille, layering is filled with filler, and the direction earthwork grille number of plies is determined according to original soil bearing stratum depth.
Oil tank reinforced earth protection body of the present utility model, the material of described unidirectional geo-grid and pitman is high density polyethylene (HDPE), and the material of direction earthwork grille is polypropylene, and filler is soil or chip ballast; Geo-grid carbon black content is no less than 2%, and Granular composite is even, lustrous surface.
The construction method of oil tank reinforced earth protection body of the present utility model, its special character is: comprise the following steps: (1) lays ground; (2) main body bottom completely spreads unidirectional geo-grid, metope parcel planting soil, and outer side slope lays turf, and inner vertical metope code bag makes real, and filler divides two-layer backfill, and after compacting, every layer thickness is 60 centimetres, adopts machinery or hand compaction; (3) unidirectional geo-grid outside interlayer from the second layer adopts pitman to carry out being connected with last layer and reserve geo-grid with inner side and strain, and mount, laying turf are planted, inner side code bag in outside again code, and filling compaction, until design elevation; (4) the unidirectional geo-grid anti-package of the last one deck in top; (5) tank body top completely spreads filler, manually makes real, and direction earthwork grille laid by filler, continues filler, manually flattens, makes real; (6) second layer direction earthwork grille laid by tank body vault, backfill compacting after last one deck unidirectional geo-grid connection tank body top direction earthwork grille entirety of reinforced earth protection body top anti-package also expires turfing or grass-seed, tank body vault continues upper soil to design elevation, manually flattens, makes real and expire turfing or grass-seed.
The beneficial effects of the utility model are: this oil tank reinforced earth protection body adopts Fill Reinforced With Geogrids flexible structure, because the unidirectional geo-grid of high density has unique durability, high strength, invasion and attack not by strong wind, rainwater destroy, extend its application life, solve traditional earthing oil tank large volume earthwork evacuation, transport, occupation of land and cannot the difficult problem of earthing.Meanwhile, also have greening and environmental protection, hidden, camouflage, not easily to give away one's position and the advantage such as cost is low, both protected the permanent of tank body, and additionally reduced land used and earth volume, easy construction, speed are fast, and have good adaptive capacity to ground.For 10 meters of high oil tanks: adopt the utility model oil tank reinforced earth protection body can save earth volume about 50% than traditional oil tank earthing, save land area about 60%.This project Fill Reinforced With Geogrids be propose in current domestic the first national standard use new technology, new technology, new construction, new material typical case, there is domestically leading level, also the beginning of national defence and front oil strategic reserves engineering use flexible structure scheme has been started, the basis making oil tank reinforced earth protection body engineering be difficult to carry out scheme in tradition steps a significant step, further extensive use will have been obtained gradually in similar or Other Engineering from now on.
