Description

Technical Field

[0001] This utility model relates to the technical field of shallow circular silo wall construction, and in particular to a small-scale test sliding device. Background Technology

[0002] The construction of shallow circular silo walls typically employs slipform construction technology. For example, patent application CN113006468A describes a slipform construction method for shallow circular silos, including the following steps: S1 material preparation, S2 measurement and layout, S3 formwork installation (using the formwork to delineate the silo wall to be poured), S4 platform construction, S5 jacking and fixing, S6 concrete pouring (initial slipforming), and S7 normal slipforming. This slipforming process is continuous; once the concrete at the bottom of the silo wall has hardened to a certain degree and reached a certain structural strength, the formwork is vertically raised a certain height, and concrete pouring continues. Therefore, the setting properties of the concrete used have a significant impact on the slipforming speed and quality. However, concrete with the same composition exhibits different setting properties under different climatic conditions, so a concrete mix formula suitable for the local climate of the project site needs to be determined before the construction of shallow circular silo walls. In actual operation, technicians adjust the concrete formula on-site to meet construction requirements. However, this concrete formula relies on the experience of construction workers and needs to be verified in step S6. If the verification fails, the concrete formula needs to be readjusted and the site cleaned up in preparation for re-verification. The verification cost of a suitable concrete formula remains high. There is an urgent need for a device that can reduce the cost of concrete formula verification. Utility Model Content
