Abstract

The invention provides a strength detection device for tunnel wall construction. The strength detection device comprises a resiliometer, a mounting base, a top cover, supporting legs, a positioning base, a height adjusting frame, a horizontal adjusting frame, an adjusting lead screw and a motor. The mounting base is movably connected to the upper portion of the horizontal adjusting frame, the mounting base is also movably connected to the upper portion of a horizontal scale frame, a front sliding frame is fixedly connected to the front portion of the lower surface of the mounting base, a rearsliding frame is welded to the rear portion of the front sliding frame, and an upper sliding frame is fixedly connected to the upper portion of the mounting base; the two ends of the adjusting lead screw are movably connected to the surface of the mounting base through bearings. The motor is fixedly connected to the bottom surface of the mounting base; and the resiliometer is movably connected tothe upper part of the mounting base. Compared with an existing method for measuring the hardness of concrete through a resiliometer, the strength detection device has the advantages that the mechanical support is used for conducting constant-speed feeding, measurement errors caused by factors such as angle deviation and unstable feeding speed easily occurring in the manual measurement process areavoided, and the measurement precision is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel wall strength detection equipment, and more specifically relates to a strength detection device for tunnel wall construction. Background technique [0002] After the tunnel is opened, concrete needs to be used to reinforce the inner wall. After the processing is completed, the hardness of the concrete is tested using a rebound hammer. The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The bullet rod deforms the local concrete and absorbs part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the hammer. When all the rebound kinetic energy is converted into potential energy, the rebound of the hammer reaches the maximum distance. The instrument will measure the maximum rebound distance of the hammer by The rebound value (the ratio of the maximum rebound distance to the initial length of the spring) is displayed in the n...
