The utility model discloses tunnel face extrusion deformation monitoring equipment, and belongs to the technical field of tunnel engineering. The monitoring device is composed of a PVC measuring pipe,a rubber sleeve and a laser scanner. The specific use method is as follows. The measuring pipe is formed by connecting a series of PVC threaded pipes through a rubber sleeve. One end of the PVC pipeis a semi-sealed section; t-shaped crossed fluorescent lines are arranged along the diameter and radius of the semicircle of the semi-sealed section; the intersection point is used as a measuring point; the method comprises the steps that firstly, a PVC pipe is constructed, then a measuring pipe is inserted into a tunnel face rock-soil body, grouting is conducted to enable the PVC pipe and the rock-soil body to be cemented firmly, then a laser scanner is used for collecting three-dimensional coordinates of all measuring points of the PVC measuring pipe at different time periods, finally, dataare processed, and settlement displacement and horizontal displacement of soil bodies at different depth measuring points in the axial direction of a tunnel can be obtained. The device is easy to operate, human influence factors in the monitoring process are reduced to the maximum extent, monitoring data can reflect settlement deformation and extrusion deformation of soil in front of a tunnel faceto the maximum extent, and a basis is provided for evaluating the influence of construction on the stability of surrounding rock.
