At present, the construction of large industrial plants becomes an effective assistance method for poverty elimination, hardness elimination and comprehensive rehabilitation realization in various cities, the demands of emerging industrial parks in various cities on the plants are increasingly strengthened, the problems of short construction period, high requirements and more process conversions generally exist in the construction process of the large plants, and the pouring of the upright columns and the ground beams is the key for the technical quality control of the plants. There are three main methods for constructing the columns and the ground beams nowadays:

1) firstly, completing all earthwork backfilling, then performing reverse excavation, and finally completing integral pouring of the stand column and the ground beam; however, in this method, the reverse excavation has a problem of repeated excavation and filling of earth, and has a high requirement for precise construction and a long construction period.

2) The second method is that firstly, the upright post pouring is completed, the ground beam steel bars are reserved, then the earthwork backfilling is carried out, the ground beam and the steel bars reserved on the upright post are dug out, then the ground beam is constructed (the steel bars are bound, the mold is filled and the pouring is carried out), and finally the residual earthwork is backfilled; however, the method has complex processes, and the processes need to be matched with each other; the waiting time of the two concreting of the upright post and the ground beam is long; the reserved ground beam reinforcing steel bar is not easy to excavate mechanically, the manual excavation work amount is large, and the efficiency is low; the steel structure anchor bolt pre-buried on the stand is destroyed easily.

3) And thirdly, firstly, completing foundation pouring, then pouring the upright posts and the ground beams, and finally backfilling earthwork after all pouring and curing are completed. However, in the method, the concrete curing time is long, and the earthwork backfilling waiting time is long; the backfill soil under the ground beam is not easy to tamp, the construction difficulty is high, and the quality of the backfill soil cannot be guaranteed.

In the method, the construction of the upright column and the backfilling of the foundation earthwork are carried out in a staggered manner, so that the construction period of the project is prolonged.
