A detection device for detecting load-bearing deformation of concrete foundation

Abstract

The invention discloses a detecting device for detecting concrete foundation bearing deformation. The detecting device has a rigid support platform; a gantry component is fixed on the rigid support platform, and has a top beam and two stand columns perpendicular to the top beam; the gantry component is perpendicularly mounted on the rigid support platform by two stand columns; a concrete foundation test block is placed on the rigid support platform between the two stand columns; the peripheral outer wall of the concrete foundation test block is coated with a rubber gasket, a heating boundary stopper and a boundary restraint block in sequence from inside to outside; the boundary restraint block is fixed on the rigid support platform between the two stand columns; a strain sensor and a temperature sensor are embedded in the upper surface of the concrete foundation test block in a staggered manner at intervals; and a hydraulic jack capable of sliding along the top beam is mounted on the top beam of the gantry component. The detecting device can detect the strain condition borne by the concrete foundation test block through adjusting the magnitude of pressure applied to the concrete foundation by the hydraulic jack.

Description

technical field [0001] The invention relates to a detection device for detecting bearing deformation of a concrete foundation. Background technique [0002] In the field of construction engineering, the concrete foundation is considered as a rigid body in the process of foundation construction, and attention is paid to problems such as cracks and fractures of concrete. However, in the field of mechanical engineering, more attention is paid to the influence of micro-deformation of the concrete foundation on the accuracy of machine tools, especially for large electromechanical equipment. It is said that its large self-weight and large load characteristics, its working accuracy and life are affected by the deformation of the concrete foundation, especially the low bearing capacity caused by the insufficient rigidity of the concrete foundation, which directly leads to the bearing deformation of precision equipment and seriously affects the equipment. Working accuracy and accurac...
