Large-scale tank body foundation provided with communication channels, and construction method of large-scale tank body foundation

Abstract

The invention discloses a large-scale tank body foundation provided with communication channels, and a construction method of the large-scale tank body foundation, and solves the problem that a conventional large-scale tank body provided with reinforced concrete channels which communicate with each other is liable to incline and topple over. A box-shaped concrete inner channel (4) which is independently cast is formed in the inner side of an inner and outer channel communication hole (3); asphaltic felt (9) is arranged between the box-shaped concrete inner channel (4) and the inner side wall of a rigid concrete annular wall (2) near the inner and outer channel communication hole (3); a box-shaped concrete outer channel (10) is arranged on the outer side of the inner and outer channel communication hole (3); the rigid concrete annular wall (2) outside the box-shaped concrete inner channel (4) which is independently cast is filled with grading sandy gravel (5); an asphaltic sand pad layer (6) is arranged on the top end surface of the grading sandy gravel (5); and a large-scale tank body (7) is arranged on the asphaltic sand pad layer (6). The large-scale tank body foundation is low in construction difficulty, and low in investment cost.

Description

technical field [0001] The invention relates to the foundation of a large tank body such as a water tank or an oil tank in a water system or an oil system in a thermal power plant, in particular to a foundation and a construction method for passing through a pipeline at the foundation bottom of a large tank body. Background technique [0002] In the water system or oil system of large and medium-sized thermal power plants, large-scale tank equipment such as desalted water tanks, spray water tanks or fuel tanks with large capacity need to be installed. Connected reinforced concrete trenches. Due to the heavy weight of large storage tanks, their structures are mostly thin-walled steel structures, which are sensitive to uneven settlement of the foundation. Therefore, the tank foundations are generally designed as rigid ring walls filled with graded sand and pebbles. However, the trench penetrating into the tank foundation is a reinforced concrete rigid structure, and two rigid...
