The paper presents the technology of measurements of a cover of a self-propelled spraged shutter provided for forming of power tunnel lining. The construction of the shutter, measuring procedure and the method for elaborating of results are discussed. Measurements of the cover are carried out in 2 steps. First, the edge points are measured by means of the method for fitting collimation datum plane and technical levelling. Next, the medial points in nodal points of the meridionial-parallel network are observed by means of a relative method using of a suitable device. Accuracy of the measurements of cover deformations up to +- 2 mm has been achieved. (Author)
