Foundation pit operation monitoring device

Abstract

The application relates to a foundation pit operation monitoring device, which comprises a main frame body and an auxiliary device. The auxiliary device is installed on the main frame body. The auxiliary device comprises a light emitting part and an optical assembly. The light emitting part is used for emitting a light beam towards the foundation pit. The optical assembly is arranged on the propagation path of the emitted light of the light emitting part and is used for diffusing the emitted light beam to form a columnar light beam to assist the foundation pit operation. During operation, the light emitting part emits a light beam towards the foundation pit. After passing through the optical assembly, the light beam is diffused to form a columnar light beam. The operation personnel can excavate the foundation pit according to the columnar light beam, for example, excavate the foundation pit along the periphery of the columnar light beam so that the pit wall of the foundation pit coincides with the periphery of the columnar light beam. In this way, the verticality and the cross-sectional size of the foundation pit excavation can be ensured, thereby improving the construction quality of the foundation pit.
