Problems solved by technology
However, due to the geological layer conditions of the foundation or the uneven weight distribution in the storage tank, or the cement foundation has been weathered for a long time, the fixing bolts are loosened, or the bad weather, strong wind, hail or ice and snow may cause the large storage tank to tilt, causing safety hazards.
So far, there is no ideal method to solve the technical problem of tilting large storage tanks

Embodiment
[0010] refer to Figure 1-3 , The caisson foundation includes a caisson main body 1, the upper part of the caisson main body 1 is provided with a sand blowing port 3, and the elevation of the caisson main body 1 is respectively provided with a sand pumping port 2, and the caisson main body 1 is filled with sand 4 with good fluidity.
[0011] When in use, the bottom plate of the large storage tank is bolted to the top plate of the caisson foundation filled with sand with good fluidity, and the horizontal position of the storage tank is adjusted by adjusting the sand in the caisson. If the storage tank is tilted, it can be adjusted by feeding sand through the sand blowing port or pumping out sand through the sand pumping port.

The invention provides a caisson type foundation, which comprises a caisson body (1). A sand-blowing gap (3) is formed at the upper part of the caisson body (1); sand-extracting gaps (2) are formed on vertical faces of the caisson body (1) respectively; and sands (4) having good flow property are filled in the caisson body (1). During use, a base plate of a large storage tank is fixed on a top plate of the caisson type foundation filled with the sands having good flow property through a bolt, so the horizontal position of the storage tank is adjusted by adjusting the sands in the caisson. If the storage tank is inclined, the storage tank can be adjusted by feeding the sands through the sand-blowing gap or extracting the sands through the sand-extracting gaps. The caisson type foundation is scientific and rational in idea and simple and feasible in method, is free from influences of geological conditions and weather conditions, and can guarantee the use safety of the large storage tank.
Description
technical field [0001] The invention relates to a caisson foundation, which is mainly used in the fields of chemical industry, petroleum, construction and road construction, and is used for fixing large storage tanks. Background technique [0002] Due to its own weight and large volume in the prior art, cement, sand and steel bars are used as the foundation during use, and the bottom plate of the storage tank is fixed on the foundation with large bolts. However, due to the geological layer conditions of the foundation or the uneven weight distribution in the storage tank, or the cement foundation has been weathered for a long time, the fixing bolts are loosened, or the bad weather, strong wind, hail or ice and snow may cause the large storage tank to tilt, causing safety hazards. . Up to now, there is no ideal method to solve the technical problem of tilting large storage tanks. Contents of the invention [0003] The object of the present invention is to provide a caisso...
