Abstract

The invention discloses a tunnel fan supporting structure bearing capacity detecting device which comprises a steel wire rope set formed by a plurality of steel wire ropes arranged side by side. Two ends of each steel wire rope are connected with a hoisting plate, and the hoisting plate is connected with an embedded part in a tunnel lining. A steel plate base is arranged in the middle of the steel wire rope set, a lifting jack is arranged on the steel plate base, a column-type weighing sensor is arranged on the lifting jack, and the top end of the column-type weighing sensor makes contact with the tunnel lining. The tunnel fan supporting structure bearing capacity detecting device has the advantages of being simple and compact in structure, low in cost, easy and convenient to install and adjust, easy to operate, stable in work, safe in structure, reliable in result, capable of being used repeatedly, suitable for various types of tunnel fan supporting structures, and the like.

Description

technical field [0001] The invention belongs to the technical field of testing equipment for structural engineering, and in particular relates to a bearing capacity testing device for a tunnel fan support structure. Background technique [0002] The installation quality of the tunnel fan is of great significance to the operation safety of the tunnel. By testing the bearing capacity of the tunnel fan support structure, the safe operation of the tunnel can be effectively guaranteed; According to Article 3.6.2.2 of the Code (JTJ026.1-1999), the structural strength of the supporting fan should be guaranteed to be more than 15 times the actual static load, and the load test of the supporting structure should be done before the fan is installed. [0003] In the prior art, there are many types of supporting equipment for testing the bearing capacity of the tunnel fan support structure, but the following disadvantages generally exist: the supporting equipment is bulky, inconvenient,...
