Embodiment approach

[0056] 1) Select the sample size of the test structural surface: select the corresponding structural surface sample according to the test design plan, and formulate the combination plan of the limit block, and conduct the direct shear test through the following sample loading process.

[0057] 2) Select the type and quantity of the limit blocks in the upper and lower plate shear boxes: in order to effectively fix the structural surface samples in the upper and lower plate shear boxes, it is necessary to select the limit blocks in the upper and lower plate shear boxes according to the sample size of the structural surface The type and quantity of blocks.

[0058] 3) Install the hoisting collar 902: the hoisting collar 902 is connected to the lug 501 of the outer frame of the lower shear box through the collar bolt 901, which can realize the connection of the lower shear box N and the lifting machine.

[0059] 4) Lifting the lower panel shear box N: hoist the lower shear box N t...

Abstract

The invention relates to a position limiting block combined multi-size structure surface shearing box, which comprises an upper disc shearing box and a lower disc shearing box, wherein the lower discshearing box comprises a position limiting block 1, a position limiting block 2, a position limiting block 3, a position limiting block 4, a lifting collar, a collar bolt and a lower disc shearing boxouter frame, the upper disc shearing box comprises a position limiting block 1, a position limiting block 2, a position limiting block 3, a position limiting block 4, a lifting ring, a position limiting block fixing bolt and an upper disc shearing box outer frame, and the combination mode and the position of the position limiting blocks of the upper disc shearing box and the lower disc shearing box are the same. According to the present invention, the position limiting block combined multi-size structure surface shearing box with characteristics of good test effect, convenient operation, short construction period, low cost and small occupation space is provided.

Description

technical field [0001] The invention relates to a combined multi-size structural surface shear box based on limit blocks, which is suitable for indoor direct shear tests on structural surfaces of various sizes, and belongs to the field of engineering technology. Background technique [0002] In human engineering activities, engineering accidents caused by rock mass deformation and instability emerge in endlessly, causing huge loss of life and property. The study of the size effect of the rock structural plane is of great significance to guide the stability of rock mass engineering. A series of dimensions (100mm×100mm, 100mm×150mm, 100mm×200mm, 150mm×200mm, 200mm×200mm, 200mm×250mm, 250mm × 250mm, 200mm × 300mm, 250mm × 300mm, 300mm × 300mm) direct shear test of the rock structural surface, the rock structural surface shear box of the corresponding size is required, and the usual practice is that each size of the rock structural surface sample needs A shearing box that match...
