As preferably, described top comprises top cover and supports the supporting structure of top cover, in cap base, one circle top cover bearing ring is set.Supporting structure is for strengthening the stability of top cover, and bearing ring is for the structural strength of further reinforced top.
As preferably, upper strata pearlife concrete ring beam, load distribution plate that foam glass brick is set in lower floor's pearlife concrete ring beam of foam glass brick, middle cement board, ring bottom being followed successively by from top to bottom, described bottom heat insulation layer are set in cement board, ring, the outer tank bottom of described outer pot bottom is placed under the cement board of bottom and is placed on concrete foundation platform, in the middle of described middle pot bottom is placed in, on cement board, the interior tank bottom of described interior pot bottom is placed on load distribution plate.The intensity of foam glass brick is high and can be adiabatic well.
As preferably, on the outer wall of described outer tank, middle tank and inner canister, some crab-bolts are set respectively, in crab-bolt end Transducers Embedded in Concrete basic platform.Crab-bolt, for strengthening the stability of each tank, is able to take the effect such as earthquake loading, wind load.
As preferably, on described outer tank, middle tank and inner canister inwall, some stiffening rings are set respectively.Stiffening ring is for strengthening the intensity of outer tank, tank and inner canister, so that tank body is not easy distortion in the time receiving External Force Acting.
As preferably, the thermoinsulation material of filling in the interlayer heat insulation layer between interlayer heat insulation layer and middle tank and outer tank between described inner canister and middle tank is pearlife and glass fibre elasticity blanket.
As preferably, described inner canister, middle tank entirety are stainless steel manufacture, and described outer tank is low alloy steel manufacture.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, be made up of three layers of inner canisters, middle tank, outer tank, under normal operating conditions, inner canister stores liquid, the whole fluid product of the lower tank stores of situation leaking in inner canister, and the boil-off gas of LNG Liquefied natural gas is by outer tank stores;
2, compared with single appearance tank, when inner canister is leaked, no liquid, gas escape; Compared with double volume tank, boil-off gas cannot be overflowed, and therefore entirely to hold tank Safety performance high for three wall metals;
3, invest lowly, be about prestressed reinforced concrete and entirely hold 1/3 of tank cost; Construction period is short, is about prestressed reinforced concrete and entirely holds 1/2 of tank construction period;
4, three wall metals hold tank entirely without cofferdam, and floor space is little, the occasion that applicable Safety performance is had relatively high expectations, natural condition are severe.
