The invention provides an injection forming mold and method for measuring the undulating form of a structural surface. The forming mold comprises fixed supporting rods anchored in an engineering rockmass, a frame-shaped piece covering the surface, with undulating form to be measured, of the engineering rock mass, a communicating pipe arranged on the frame-shaped piece and used for injecting an injection molding material into the frame-shaped piece, sealing gasket bases used for sealing gaps between the bottom of the frame-shaped piece and the engineering rock mass, as well as counter-force arm rods and limiting arm rods, wherein one ends of the counter-force arm rods and limiting arm rods are rotatably arranged on the fixed supporting rods and the other ends of the counter-force arm rodsand limiting arm rods are in contact with the frame-shaped piece, the counter-force arm rods are in contact with the top face of the frame-shaped piece, the limiting arm rods are in contact with the side faces of the frame-shaped piece, the counter-force arm rods and the limiting arm rods are used for extruding and fixing the frame-shaped piece to the surface, with the undulating form to be measured, of the engineering rock mass, and the injection molding material is injected into the frame-shaped piece through the communicating pipe and contains the undulating information of the structural surface after being solidified. The mold and method are not limited by engineering site conditions, the formed plastic part containing the undulating form of the structural surface can be manufactured on site, and the information of the undulating form of the structural surface can be represented through the injection molding material.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an injection molding mold and a method for measuring the undulation shape of a structural surface. Background technique [0002] Engineering rock mass is composed of rock and structural planes, and the rock mass structure type controlled by structural planes is an important factor affecting the stability of rock mass under engineering loads. The long-term research on the structural plane of rock mass shows that the topographic features such as undulation and roughness are one of the important factors affecting its mechanical parameters. The most popular way to obtain the shape information of structural surface fluctuations is to use 3D scanning technology. The principle is to project additional energy (such as visible light) to the object, and calculate the 3D spatial information through the reflection of energy. The indoor laboratory has good light and is easy ...
