Abstract

The invention discloses a multifunctional testing device used for a lining structure. The multifunctional testing device is composed of a counterforce apparatus and a loading module. The counterforceapparatus is produced by bending and welding steel plates. The loading module is composed of a hydraulic jack, a force-transmission steel plate, a stratum spring, a steel base plate, and a rubber baselayer. One end of the jack is connected with the counterforce steel plate, the other end is connected with the stratum spring through the force-transmission steel plate, and the other end of the stratum spring is connected with the steel base plate and the rubber base layer. The multifunctional testing device has the advantages of simple processing production, good integral stability, and convenient operation, and has integral and local loading function. The multifunctional testing device can be widely used for the lining structure tests of tunnels under various conditions such as bias, relaxground pressure and lining backside cavity.

Description

technical field [0001] The invention belongs to the field of tunnel and underground construction engineering, and relates to a multifunctional device for researching lining structure tests. Background technique [0002] The preliminary study of my country's 13th Five-Year Development Plan aims to "deeply promote the development of the western region, promote the construction of national key infrastructure to the western region, accelerate the improvement of the railway and highway skeleton network in the western region, and solve the problem of the "short board" of transportation in the western region." "As a work focus. Most of the western regions of my country are mountainous. In order to improve the route alignment, shorten the mileage, and increase the operating speed, it is necessary to build roads or railway tunnels in many cases. How to ensure the safe and normal operation of traffic tunnels in the western region is one of the important research contents to achieve th...
