And the second method comprises the following steps: because the total station is not easy to place or operate at the circle center position, the steel tape is adopted for monitoring, one end of the steel tape is fixed at the circle center, and the other end of the steel tape is rotated and measured.
During winter construction, the early strength agent is added into the concrete, so that the concrete can meet the requirement of form removal strength in advance, the scaffold (high-formwork scaffold is large in usage amount and high in overall lease cost) can be detached as early as possible, the utilization rate of turnover materials is improved, or the lease cost of the materials is reduced.
After concrete pouring is finished, a specially-assigned person is dispatched to use the total station to recheck and check the bolt by adopting the same method, and maintenance is well done.
Specifically, the construction of the special-shaped ring beam is divided into four flow construction sections according to the expansion joints, each flow construction section comprises two special-shaped ring beams with the same specification, and flow operation is adopted, so that the utilization rate of turnover materials is greatly improved, the construction efficiency of the second section and the later construction sections is greatly improved, and the work group and work nest phenomenon caused by simultaneous operation of all the sections is avoided.
