In the soil foundation pit engineering monitoring project, the horizontal displacement of the deep layer is a project to be measured in the first-level foundation pit and the second-level foundation pit of the safety grade, and a project to be measured is suitable for the third-level foundation pit of the safety grade. Generally, the horizontal displacement of the deep layer of the monitored soil body is preferably arranged at the middle part, the external corner and the representative part of the periphery of the foundation pit. When the horizontal displacement of the deep layer is observed by an inclinometer, an inclinometer pipe needs to be drilled and embedded in the soil body. The common inclinometer pipe is generally made of PVC, ABS and aluminum alloy materials, the pipe length is usually 2 meters for convenient transportation and construction embedding, the joint part is made of the same material with the length of about 0.2m, and the joint part is butted according to the design length when being embedded in soil. In the in-service use, because the problem of joint department leakproofness, often can appear advancing the phenomenon of soil in the deviational survey pipe, the granule of silt is too little, and it will be intraductal along deviational survey union coupling gap entering through water pressure to meet water, so can cause the bottom of deviational survey pipe to be full of earth for a long time, and the deviational survey pipe is abolished, monitoring data's disappearance.
