Abstract

The invention discloses a structure of apparatus and buttress integrated foundation in a steam turbine room; the structure comprises a raft; a pad layer is arranged below the raft; plain fills for backfilling after all the apparatus and buttress integrated foundation in the steam turbine are constructed, are arranged above the raft. With the adoption of the basic structure of the integrated raft, the repeated construction problem that the earth has to be excavated and backfilled for multiple times when needing to change and enlarge the apparatus and buttress integrated foundation in the steam turbine, is avoided; the unnecessary waste in the construction is avoided, the construction cost is saved, and the construction period is shortened. And the foundation structure using the above integrated raft further can effectively reduce the differential settlement between the foundations of the apparatus.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to an integral foundation structure of equipment in a steam turbine house and a support pier. Background technique [0002] Among the overall foundations of equipment and buttresses in the steam turbine house, except for deep buried foundations such as steam turbine foundations, circulating water pits, and condensate pump pits, they are all foundations or trenches for equipment with small loads and shallow buried depths. The distribution of these foundations or trenches is complex and wide, covering almost the entire area of ​​the turbine house. [0003] The practice in the prior art generally adopts independent foundations after excavation, and once the strength of the foundations reaches the standard, the earthwork will be backfilled. However, due to the frequent changes in the technology and professional materials of the project, and the large time distribution ...
