Slipform construction scheme for shallow round warehouse

Sliding form technology is applied in many engineering and construction aspects, so let’s take a look at it with the editorShallow round warehouse slipformWhat are the contents of the implementation plan of the construction plan?

1,The design of the sliding formwork device mainly adopts the stereotyped combined steel formwork; the lifting frame adopts"Door" type frame; the console should be set on the ground, and two three-stage parallel oil circuits should be connected to it; the jack should be a hybrid jack, and the operating platform is composed of an inner and outer pick frame and an inner and outer hanger.

2,In the theoretical design of sliding form steel structure, theoretical calculations and check calculations must be carried out according to the steel structure theory before construction, and some unfavorable factors such as construction load and wind load of the sliding device must be comprehensively considered. For the lower part of the inner and outer cantilevers, horizontal trusses and triangular trusses made of steel pipes are used. The two trusses form a polygonal arched three-dimensional space truss connection circle along the circumferential direction of the tube wall to achieve the overall rigidity and stability of the platform. For the silo diameter contact ring, a flexible platform composed of drum ring suspension cables is generally used. In addition, for the hydraulic lifting system, double jacks should be installed on both sides of the larger opening and the load concentration part at the same time. In order to make the platform evenly lifted, To minimize concentration.

3.In the construction of slipform concrete in the shallow round warehouse, it is necessary to control the strength of the concrete from the mold to ensure the quality of the concrete. If the strength of the mold is too small, then the phenomenon of concrete flow and mortar will appear on the wall of the cylinder, and the strength of the concrete from the mold is too high. Will cause cracks and scratches on the silo wall. In the hot summer season, water reducing agent should be added to the concrete during construction to reduce water consumption, delay the time of concrete setting and improve the workability of concrete, and configure day and night according to the large temperature difference between day and night in the local area. The mix ratio of the concrete can meet the requirements of the slipping speed for the strength of the concrete from the mold.
