Description

Assembled earthing brick wall structure and construction method thereof Technical Field The invention belongs to the technical field of earthing tanks, and particularly relates to an assembled earthing brick wall structure and a construction method thereof. Background The storage tank is arranged in an underground shelter which consists of a protective wall and a top cover. The protective wall is prefabricated by bricks, stones and concrete or is formed by casting concrete in situ, and the storage tank in the form is commonly called a earthing tank or an earthing storage tank. Compared with a storage tank directly exposed to the external environment, the use of the earthing storage tank can reduce evaporation loss and delay deterioration of petrochemical products stored in the tank. Because the earthing storage tank has good tightness, and the top and the periphery are covered with soil with the thickness of not less than 0.5m, the indoor air temperature of the tank is stable, the influence of the atmospheric environment temperature is small, the breathing volatilization loss of the storage tank is reduced, and the deterioration of petrochemical products is delayed. The earthing tank has certain protection capacity for hiding effect on air, and is safe, and the earthing tank can hide the storage tank well through earthing and vegetation covering, so that the possibility of enemy detection and enemy detection is reduced. In addition, the storage tank chamber protection body has certain protection capability, not only can resist certain attack of enemies, but also can prevent open overflow after the storage tank fires and explodes, and lighten the influence degree on the adjacent storage tank. The construction process of the prior art earthing tank usually comprises the steps of firstly excavating a certain space downwards on a flat land or a hillside, constructing a storage tank, then constructing a tank room retaining wall, casting a protective body vault, and the like, assembling storage tank accessories, and finally carrying out earthing treatment.
