Description

Technical Field

[0001] The present application relates to the technical field of foundation pit settlement detection devices, and in particular to a foundation pit settlement detection device. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to make the earth slope stable. The slope size is determined according to relevant construction regulations. For deeper excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits even use underground continuous walls and column-type bored cast-in-place pile interlocking methods to prevent the outer soil layer from collapsing. In order to prevent the foundation pit settlement from damaging the building, detection devices are often used during the construction process to conduct real-time detection of the foundation pit settlement, so as to facilitate timely measures.

[0003] When the existing detection device is used, a static level is usually used to detect the settlement of the foundation pit in real time. The static level is fixedly installed at a detection point in the foundation pit that is flush with the reference point. When the detection point undergoes a longitudinal relative displacement change, the high-precision pressure sensor in the static level senses the internal liquid pressure change, thereby detecting the foundation pit settlement through the pressure change.

[0004] However, when using the above method for detection, in order to prevent the static level from being moved by external forces during use and thus affecting the detection, it is often necessary to fix the static level on the stone pier or wall at the detection point. Usually, a mounting hole is opened on the stone pier or wall, and then expansion screws are installed in the mounting holes in sequence. The static level is fixed by the expansion screws. This method is often troublesome to operate, and the process of installing the expansion screws is time-consuming and laborious, and the loading and unloading efficiency is often relatively low. Therefore, those skilled in the art provide a foundation pit settlement detection device to solve the problems raised in the above background technology. Utility Model Content
