Abstract

The invention relates to a measuring device for the foundation pit deformation and a measuring method. The measuring device comprises a measuring structure body and a tilt measuring device. An embedded working cement block fixes the measuring structure body near the contact point of the foundation pit to be tested. The side of the measuring structure body close to the contact point is provided with a probe system. The displacement deformation of the foundation pit is obtained by measuring the distance between the probe of the probe system and the contact point. The tilt measuring device can berotatably disposed inside the measuring structure body for correcting measurement errors caused by tilting of the measuring structure body. According to the measuring device for the foundation pit deformation and the measuring method, the deformation of the foundation pit can be measured in real time, and the hysteresis problem of the measurement results in the existing foundation pit deformationmeasurement is effectively solved.

Description

technical field [0001] The invention relates to a foundation pit deformation measurement device and a measurement method, belonging to the technical field of foundation pit construction engineering. Background technique [0002] At present, my country's infrastructure has entered the peak period of construction and is developing rapidly. Most engineering projects will carry out the construction of foundation pit excavation. During the excavation process of the foundation pit, a large amount of materials are stacked around the foundation pit due to site restrictions. , and layered excavation makes the pit bottom uneven, or changes in the geological conditions of the excavation section will cause the foundation pit to be in a state of asymmetric stress, which will cause uneven deformation of the foundation pit. [0003] The foundation pit is often accompanied by strong environmental effects during the construction, and the excavation of the foundation pit can easily cause the c...
