Description

Technical Field

[0001] The invention relates to the technical field of foundation monitoring, and in particular to a building foundation settlement monitoring system. Background Art

[0002] With the development of construction technology, various types of formwork systems must be used in the construction of cast-in-place concrete structures. In the construction of cast-in-place concrete structures, engineering accidents of formwork collapse often occur. The main reasons for the safety accidents of formwork collapse are multifaceted, such as excessive formwork bearing load, excessive deformation of the formwork itself, insufficient bearing capacity of the foundation of the formwork support frame, etc. Due to the above reasons, the formwork support frame components fail, local collapse or overall instability occurs, resulting in engineering damage and malignant safety and quality accidents such as casualties of on-site workers. With the development of social economy and the advancement of science and technology, the scale, space and volume of construction projects are gradually increasing, and the plane and facade of buildings are more complex and diverse, so higher requirements are needed for the safety management of formwork construction.

[0003] In the analysis of template collapse and instability accidents, accidents caused by foundation problems account for a large proportion. The foundation of the template support frame is not properly treated, or the construction is not strictly carried out according to the construction specifications, resulting in insufficient foundation bearing capacity, settlement during the concrete pouring process, and the sinking of the support frame and excessive deformation of the frame are the main causes of template safety accidents.
