Abstract

The invention discloses a pre-stressed anchor rod for an underground engineering model test. The pre-stressed anchor rod comprises a rod body, trays, a spring and a nut, wherein the two trays and the nut are sleeved on the rod body in sequence; and the spring is also sleeved on the rod body and arranged between the two trays. The invention also discloses an operation method for the pre-stressed anchor rod for the underground engineering model test. The operation method comprises three steps including drilling, installing the anchor rod and applying pre-stress. By the pre-stressed anchor rod. the problem of simulation of the pre-stressed anchor rod in the model test is solved, and the pre-stressed anchor rod has the advantages that (1), the manufacturing is simple and the cost is low; (2), the dimension of the anchor rod and the pre-stress are adjustable, so as to satisfy various similarity ratio requirements of the model test; (3), and the pre-stressed anchor rod can be widely used for geomechnical model test research in such underground engineering fields as water conservancy, traffic, mine and the like.

Description

technical field [0001] The invention relates to a geomechanics model test technology, in particular to a prestressed anchor rod used in an underground engineering model test and a construction method. Background technique [0002] The geomechanics model test is to convert the actual project into an indoor model for test simulation according to the similarity theory, which is conducive to highlighting the main contradictions in the complex test process, and is easy to grasp and discover the inner connection of the phenomenon. Among them, the underground engineering model test is the tunnel It is an effective method and means to conduct simulations for underground projects such as mines, coal lanes, etc., and to guide the design and construction of underground projects. In the underground engineering model test, after the cavern is excavated, it is necessary to simulate the support of the cavern, such as simulated bolt support. Prestressed anchors still lack effective means, ...
