During the construction process of foundation pit excavation, in order to prevent landslides and ensure construction safety, when the excavation depth or filling height of excavation or filling exceeds a certain limit, a slope with a certain gradient should be made at its edge. The slope gradient of the foundation pit is an important factor directly affecting the stability of the foundation pit. Therefore, it is necessary to detect the slope gradient. At present, the measurement method is mainly used for detection, with large detection errors, and it is impossible to detect the slope change point, and the scope of use is relatively narrow. Content of the Utility Model

[0003] The purpose of this application is to provide a foundation pit slope detection device to solve the problems of large detection errors, inability to detect slope change points, and relatively narrow scope of use in the existing slope detection methods.

[0004] To solve the above technical problems, this application provides a foundation pit slope detection device, including:

[0005] A bottom plate, on which a plurality of threaded fixing rods are screwed. An installation groove penetrating through the bottom is provided at a position near one end of the bottom plate. A measuring plate is rotatably installed in the installation groove through a connecting shaft. An expansion rod is hinged on the bottom plate, and the upper end of the expansion rod is hinged to the bottom side of the measuring plate. An angle gauge corresponding to the measuring plate is fixed on one side of the bottom plate. One end of the bottom plate away from the expansion rod is rotatably installed with a connecting rod through an installation component, and a digital display inclinometer is fixed at the lower end of the connecting rod.

[0006] On the basis of the above embodiment, as a preferred embodiment, the installation component includes an installation rod, both ends of which are threaded. One end of the installation rod penetrates through the connecting rod and extends into the bottom plate, and a limit nut is screwed on the other end of the installation rod.

[0008] On the basis of the above embodiment, as a preferred embodiment, a pointer fitting the angle gauge is further fixed on one side of the upper end of the measuring plate.

[0009] It should be detailed in the solution that the lower ends of the threaded fixing rods are all pointed.

[0010] On the basis of the above embodiments, as a preferred implementation manner, the operation handle and the connecting rod are integrally formed.

[0011] Compared with the prior art, a foundation pit slope detection device provided by the utility model includes a bottom plate. A plurality of threaded fixing rods are screwed on the bottom plate. An installation groove with a bottom-through structure is arranged at a position near one end of the bottom plate. A measuring plate is rotatably installed in the installation groove through a connecting shaft. A telescopic rod is hinged on the bottom plate, and the upper end of the telescopic rod is hinged to the bottom side of the measuring plate. An angle protractor corresponding to the measuring plate is fixed on one side of the bottom plate. One end of the bottom plate far away from the telescopic rod is rotatably installed with a connecting rod through an installation component, and a digital display inclinometer is fixed at the lower end of the connecting rod. When in use, the bottom plate needs to be placed on a flat slope, and the measuring plate is located at the slope change point. Press down the bottom plate to insert the lower ends of the threaded fixing rods into the soil, and adjust the insertion depth of each threaded fixing rod according to the actual situation by screwing the threaded fixing rods to improve the fixing firmness of the bottom plate. Then, control the telescopic rod to stretch and drive the measuring plate to rotate so that the measuring plate is closely attached to the slope change point. At this time, by reading the position of the measuring plate on the angle protractor, the angle of the slope change point can be obtained. Subsequently, by operating the installation component and rotating the connecting rod to drive the digital display inclinometer to act and fit with the slope, the value displayed on the digital display inclinometer at this time is the angle of the slope.
