Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] In concrete implementation, the present invention is realized by the following steps:

[0010] Step 1: Use a hammer and a steel drill to remove the rocks loosened by the cannon at the test point;

[0011] Step 2: Find a relatively flat place on the left and right walls of the cave or the top and bottom of the cave next to the test point, or manually chisel it, erect the first support beam 2a, and install wires on both ends of the first support beam. The rod or hydraulic device 3 is pushed against the wall of the cave, and the lead screw or hydraulic device is adjusted to make it tight to ensure firmness;

[0012] Step 3: Based on the length of the first support beam, select the second support beam 2b so that it is at the same height as the first support beam, install screw or hydraulic device on both ends of the second s...

Abstract

The invention relates to a preparation method of a rock mass sample. The problems that a current rock mass test piece is difficult to prepare, the cost is high, the operation is fussy, the period is longer, and the efficiency is low can be effectively solved. The method comprises the following steps of: eliminating a stone which is shaken loosely at a testing point, digging out a plane on a hole wall near the testing point, erecting a first supporting beam on the plane, leaning two ends of the first supporting beam against the hole wall, and then erecting a second supporting beam on the same plane of the first supporting beam in a parallel way, respectively leaning two ends of the second supporting beam against the hole wall, vertically hinging a third supporting beam sliding freely on the first supporting beam and the second supporting beam, and then mounting an electric core drilling device freely sliding on the third supporting beam, positioning the electric core drilling device above a testing plane for locking; drilling the prominent part of the testing plane to a determined height by using a drilling head, drilling to remove a convex part, and grinding the testing plane to make into the test piece in a rock mass deformation test. The equipment in the method provided by the invention is simple, is easy to mount and use, and is easy to operate; the cost is low; the efficiency is high; and the purpose is wide.

Description

technical field [0001] The invention relates to a rock mass sample, in particular to a method for preparing a rock mass sample. Background technique [0002] At present, the preparation of rock mass test specimens relies on stonemasons to dig out rock masses with chisels and hammers; The cost is high, and the operation is cumbersome, the cycle is long, and the efficiency is low, which has gradually become incompatible with the current rock mass test technology. Therefore, it is imperative to innovate and improve it. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a method for preparing rock mass samples, which can effectively solve the difficulties in preparing rock mass test specimens, high cost, cumbersome operation, long period, The problem of inefficiency. [0004] The technical scheme solved by the present invention is to remove the loose stones ...
