Automatic foundation pit support monitoring system

Abstract

The invention discloses an automatic foundation pit support monitoring system. The automatic foundation pit support monitoring system comprises an enclosure body, an anchor cable axial force monitoring device is arranged on the enclosure body and comprises an anchor cable arranged on the enclosure body in a penetrating mode and a tensioning mechanism used for providing tension for the anchor cable, one end of the anchor cable is poured into a slope body, a hole allowing the anchor cable to penetrate is formed in the enclosure body, and the tensioning mechanism is arranged at the end, away from the slope body, of the anchor cable and clamps the anchor cable. The anchor cable axial force monitoring device further comprises an anchor cable meter, the anchor cable meter and the anchor cable are concentrically arranged, an angle adjusting assembly is arranged on the enclosure body, a sleeve is arranged between the anchor cable meter and the tensioning mechanism, and the sleeve abuts against the anchor cable meter and the tensioning mechanism. Tensioning force is provided for the anchor cable through the tensioning mechanism, stress dissipation of the anchor cable meter is monitored, so that dissipation of prestress of the anchor cable is indirectly obtained, the prestress variable quantity of the slope body around the foundation pit is judged, workers can take and formulate necessary engineering measures in time, potential safety hazards of construction are reduced, and the construction safety is improved.

Description

technical field [0001] The invention relates to the field of foundation pit monitoring, in particular to an automatic monitoring system for foundation pit support. Background technique [0002] The foundation pit is an earth pit excavated according to the base level and foundation plane size during the design of the building foundation. Foundation pit collapse is a safety accident that occurs frequently during the construction process, which not only brings a lot of economic losses, but also causes casualties. [0003] In order to reduce the probability of foundation pit collapse and reduce the losses caused by foundation pit collapse, the existing foundation pit needs to be protected and supported by support structures after excavation, and the support is monitored by testing equipment at regular intervals The deformation and displacement of the structure can be used to judge the safety of the project, detect possible collapse hazards in time, and take and formulate necess...

Problems solved by technology

[0004] However, since the deformation and displacement of the foundation pit support structure are usually affected by the stress state of the slope around the foundation pit, if the stress state of the slope around the foundation pit changes and cannot be detected in time, the support structure will be affected. Irreversible deformation, displacement, and even collapse are prone to occur due to the stress of the slope around the foundation pit, which seriously threatens the construction safety of the foundation pit
