Description
Technical Field

Background
In the construction of cement plants, silos for storing cement raw materials are important structures, and it is pointed out in "cement plant design code" GB50295-2016 that brick silos can be used when the silo diameter is less than 8m, prestressed concrete structures can be used when the silo diameter is greater than 18m and is economically permissible, and reinforced concrete silos can be used otherwise. The reinforced concrete silo has good air tightness, small influence by external temperature difference change, good moisture-proof and rain-proof effects, long service life and low maintenance cost. However, the existing common cast-in-place reinforced concrete silo has partial defects, such as more field wet operations, which can cause field pollution, and the problem of maintenance after the field wet operations, which prolongs the construction period. In addition, some equipment foundations on the cement production line are still cast in situ, and supporting house structures are mostly cast in situ frame structures, so that the construction efficiency is low, the construction period is long, and the environment is polluted.
Along with the rapid development of economy in China, more and more attention is paid to production efficiency and environment-friendly production. The prefabricated building adopts an industrialized production mode to build buildings and structures, improves the production efficiency, reduces the cost and the emission, and has great advantages in the aspects of resource and energy conservation and ecological environment protection.
The invention aims to develop a novel prefabricated assembled concrete silo, and aims to solve the defects existing in the existing common cast-in-place concrete silo system.
