The top of the adjustment structure is fixedly connected to a fixed block. The bottom of the adjustment structure is fixedly connected to a fixed structure. A second distance sensor is provided on one side of the cross plate, and a detection head is provided on one side of the second distance sensor. The utility model is convenient for the staff to operate and record. The fixing bolts fixed on both sides of the cross plate are unscrewed, the cross plate is adjusted, and the fixing bolts are fixed to both sides of the cross plate after selecting a suitable position, thereby improving the use efficiency of the device. However, there are still areas that can be optimized in the device.

[0004] The existing devices mainly detect the levelness of various parts of the foundation by manually observing and recording the level, which makes it difficult for some devices to automatically detect and record the levelness of the foundation, resulting in inconvenience for rapid detection of the foundation. At the same time, some devices mainly use fixed-specification brackets to place the level, which makes it difficult for some devices to adjust the length of the bracket according to the detection specifications, resulting in some devices being inconvenient to detect the levelness of different distance units, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a foundation detection device for civil engineering is proposed. Utility Model Content
