Description

Technical Field

[0001] The invention relates to the technical field of foundation pit support, and in particular to a multi-dimensional foundation pit support deformation monitoring system. Background Art

[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, an excavation plan should be formulated based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage should be done well. If the excavation is not deep, the slope can be stabilized by the method of side slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] The foundation pit in the prior art provides support through the support method to protect the workers in the foundation pit to complete safe operations. However, the pressure on the outer soil layer of the foundation pit is relatively large, and the support structure will collapse, thereby affecting the safety of use. Therefore, it is necessary to complete real-time monitoring of the support deformation. The prior art can monitor the support after deformation and provide alarm warnings. However, it also takes sufficient time to evacuate safely after the support is deformed. Therefore, the evacuation time is short and safety is not guaranteed. The present invention monitors the supporting soil layer and senses the risk of soil collapse in advance, thereby strengthening safety guarantees and increasing the safe evacuation time.

When the thrust of the soil layer is large, the support steel block 10 will damage the support of the triangular steel block 9, completing the staged support effect, and the outer support sleeve 6 of the support rod 11 is fixed to the support plate 1 to achieve support firmness. One end of the support rod 11 is fixedly connected with the support plate 5, and the support plate 5 structure corresponding to the support plate 1 is fit with the surface of the soil layer 7, and then the pointed cone rod 22 is inserted into the interior of the soil layer 7.
