The invention provides a large door opening funnel ring beam reinforcing and supporting method for a large-
diameter silo slip form lifting
system, which is based on the large-
diameter silo slip form lifting
system, and the slip form lifting
system comprises a template system, an operation platform system and a hydraulic system, the construction method comprises the following specific steps in sequence: construction preparation, template system
assembly, operation platform system
assembly, hydraulic system
assembly, slip form lifting system reinforcement and slip form construction, slip form lifting system disassembly and
silo top construction. Wherein a door opening reinforcing step and a funnel ring beam reinforcing step are arranged between the slip form construction step and the slip form lifting system dismantling step. The method has remarkable effects in the aspects of construction efficiency, reinforcing and stability of a large-
diameter silo slip form lifting system, a reserved large door opening reinforcing and supporting technology in the slip lifting process and a funnel ring beam reinforcing and supporting technology, meanwhile, the situation that a large reserved opening stops sliding and waits is avoided, the forming quality and construction efficiency of concrete are improved, and the construction cost is reduced. And the
coal storage silo has wide application prospect and popularization value at the moment that the
coal storage silo becomes larger and larger.
