#-shaped reinforced open caisson for soft soil geological rotational flow tank and construction method

Abstract

The invention relates to a #-shaped reinforced open caisson for a soft soil geological rotational flow tank and a construction method. The open caisson comprises an open caisson body, wherein the open caisson body comprises a sidewall; grids connected with the sidewall are arranged at the lower part of the inner wall of the sidewall; fillers are arranged at the lower parts and blank spaces of the grids; a baseplate is arranged on the top surfaces of the grids. According to the invention, the open caisson body is manufactured on the earth surface, and then gradually sinks under the action of dead weight, plain concrete is poured into the lower parts and blank spaces of the grids for sealing the bottoms, finally, a reinforced concrete baseplate is poured on the top surfaces of the grids; the grids bear the pressure of water and soil outside the open caisson during the open caisson construction process so as to guarantee the settling velocity of the open caisson body is uniform and stable, and prevent inclination during the open caisson construction process, and after the sedimentation is completed, the grids, the open caisson body baseplate and the bottom sealing plain concrete are stressed jointly so as to guarantee the strength and safety of the open caisson baseplate. According to the open caisson and the construction method, the structure is simple, the stress is reasonable and specified, the construction is convenient, the rigidity of the open caisson and the stability in sinking are improved, and the open caisson construction safety in soft soil area is guaranteed.

Description

technical field [0001] The invention relates to an underground structure, in particular to a well-shaped reinforced caisson for a geological swirling pool on soft ground and a construction method thereof. Background technique [0002] The metallurgical industry needs to configure a large number of swirl pools, but the swirl pools have large diameters and deep buried depths, making design and construction difficult. When the geological conditions are good, the construction scheme of large excavation is generally adopted for the swirling pool. In soft soil areas, the construction scheme of large excavation is difficult to realize, and the construction scheme of underground diaphragm wall and caisson is generally adopted. The construction scheme of underground diaphragm wall construction, the swirl pool is composed of two systems of underground diaphragm wall and inner cylinder, the construction period is long and the construction cost is high. The construction scheme of the c...
