Description

Technical Field

[0001] The present application relates to the technical field of ash tank foundations, and in particular to a steel foundation for a concrete ash tank. Background Art

[0002] During the construction process, it is generally necessary to build a new concrete mixing station near the project site to mix concrete to meet the needs of the project. The mixing station is generally composed of a mixing plant, an ash tank, and a sand and gravel aggregate silo. In the construction of traditional mixing stations, the ash tank foundation is generally a reinforced concrete raft foundation, and the foundation is connected to the ash tank column with embedded bolts. However, due to the narrow terrain and limited construction site of some projects, the mixing station site is mostly a fill foundation or soft mud roadbed area. The bearing capacity of the foundation in such areas is low, and uneven settlement is prone to occur, which is not conducive to the stability of the structure. The solution is usually to replace the foundation or stabilize the natural settlement. This type of construction process has a long construction period and high cost, which is not conducive to the advancement of engineering construction. Utility Model Content

[0026] In traditional mixing station construction, the ash tank foundation is generally a reinforced concrete raft foundation, and the foundation is connected to the ash tank column with embedded bolts. However, due to the narrow terrain and limited construction site of some projects, the mixing station site is mostly a fill foundation or soft mud roadbed area. The bearing capacity of the foundation in such areas is low, which is prone to uneven settlement and is not conducive to the stability of the structure. The solution is usually to replace the foundation or stabilize it with natural settlement. This type of construction process has a long construction period and high cost, which is not conducive to the advancement of engineering construction.

[0027] In response to the above problems, an embodiment of the present application provides a concrete ash tank steel foundation, which can be cut according to the on-site terrain to construct a double-layer reinforced concrete raft slab. By combining the double-layer reinforced concrete raft slab with the steel foundation component, the concrete ash tank steel foundation can be used in complex and poor geological areas, and multiple ash tank foundations can be combined into a whole to avoid uneven settlement in weak areas, increase foundation stability, and improve the safety performance of the concrete ash tank foundation.
