Abstract

The invention relates to a measuring and warning device, in particular to a simple and convenient metro station compression resistance degree measuring and warning device. The invention provides a simple and convenient metro station compression resistance degree measuring and warning device which can further detect the ground and can reduce errors. A simple and convenient metro station compression resistance degree measuring and warning device comprises a mounting plate. The first fixing columns are connected to the bottom of the mounting plate in a front-back symmetry manner; the tires are rotationally connected to the interiors of the two first fixing columns; the rear side of the top of the mounting plate is connected with the handle; the contact switch is arranged on the rear side of the top of the mounting plate; the middle of the top of the mounting plate is connected with the second fixing column; the electric push rod is arranged in the middle of the upper portion of the second fixing column. Through the arrangement of the iron block, the iron block can further detect the ground, the detection effect is better, and then errors can be reduced.

Description

technical field [0001] The invention relates to a warning device for measurement, in particular to a simple warning device for measuring the anti-pressure degree of a subway station. Background technique [0002] With the rapid development of the times, many cities have opened subways, which have brought great convenience to people's travel. When subways are built, they are generally built underground. Dig the tunnel, and then build the subway station. After the tunnel is dug, the compressive capacity of the tunnel needs to be tested to avoid subsequent ground collapse. [0003] The existing detection device includes tires, a first fixed column, a mounting plate, a second fixed column and a test block. People usually drive the test block to move down to contact with the ground through the detection device, so that the test block can measure the resistance of the place. Whether the pressure level is qualified or not, people need to observe the testing place to see if the tes...
