Description

Cube rock sample reinforcement and repair grouting test device and its application method
Technical field
The present invention relates to rock sample test field, especially a kind of cube rock sample reinforcement and repair grouting test device and its make Use method.
Background technique
The rock mass of nature often haves the defects that a large amount of microcosmic or macroscopical, presence of these joint fissures such as joint fissure Stress field, seepage field and chemical fields inside strong influence rock mass structure, property often control entire rock mass structure Stabilization.While it is one of an important factor for influence slope deforming is with destruction that joint fissure, which is also, in engineering construction, because of section Manage crack influence and generate such as landslide, the bad geological phenomenon of the high slope instability of avalanche it is commonplace.But due to joint Crack is generally minor structure, and scale is smaller, and is distributed with certain locality;Simultaneously because joint fissure becomes with condition Change and continuous development and change, therefore, the influence of its side slope is also the process of a continuous development, and the harm of side slope also tends to With certain concealment.Therefore, in engineering geological investigation, it is not as good as large sizes such as weak structural face, karst collapse, ancient slides Geological structure is taken seriously like that, tends to ignore.After typical Three Gorges Projects are completed, the reservoir level of reservoir area of Three Gorges is substantially improved And the circulation change between 145-175 Micoud water falling zone, the region there's almost no vegetation, and ROCK MASS JOINT, crack are abundant Development, opening width is larger, and in layering disintegration, broken trend, and this destroy is in progressive development trend, the object of jointed rock mass Reason, change of mechanical property will directly affect the stabilization of reservoir stability, it is likely that make stable reservoir stability to unstable side To development.Therefore, it is badly in need of a kind of available experimental rig of laboratory to the specific joint plane of rock (by direct shear test device, system The specific joint plane produced) consolidation by grouting test is carried out, referential data is provided for field-hardened rock cranny.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of cube rock sample reinforcement and repair grouting test device and its Application method can solve the problem of can not carrying out laboratory's consolidation by grouting test to the specific joint plane of rock at present, realize The monitoring of grouting pressure during the whole test process provides referential data for construction site consolidating crack crack.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of cube rock sample reinforcement and repair filling Experimental rig is starched,
The rock sample shear surface provisions for grouting fixing bracket including height-adjustable rock sample and being matched with rock sample shear surface, Rock sample shear surface provisions for grouting is installed in the fixed bracket of rock sample;
In the fixed bracket of rock sample, connected between fixed bracket base and fixed bracket upper cover plate by the four columns of surrounding Connect, be transversely mounted under passing through respectively between the ipsilateral two root posts between fixed bracket base and fixed bracket upper cover plate item and On be transversely mounted item connection, it is each on be transversely mounted item and under be transversely mounted on item and offer at least one rock sample fixation hole respectively, Rock sample fixing bolt passes through rock sample fixation hole and matches with the rock sample to reinforcement and repair, is above transversely mounted item and is transversely mounted item under Between each column on provisions for grouting fixing bolt and lower provisions for grouting fixing bolt are installed;
In rock sample shear surface provisions for grouting, the front side strip of paper used for sealing, left side strip of paper used for sealing, the right side strip of paper used for sealing that are matched with each rock sample shear surface The square body to form an inner hollow is connected by the fixed patch of strip of paper used for sealing interface between rear side strip of paper used for sealing, front side strip of paper used for sealing is to have one Determine thickness with the rock sample open box body of contact surface, the pulp exhaust pipe with pressure gauge, front side envelope are communicated on rear side strip of paper used for sealing The inlet pipe with micro-high-pressure pump is communicated on item.
Fixed bracket base is threadedly coupled with four columns, and fixed bracket upper cover plate is vertical by cover board fixing bolt and four Column connection.
It front side strip of paper used for sealing, left side strip of paper used for sealing, right side strip of paper used for sealing and rear side strip of paper used for sealing and is installed on rock sample by rubber sheet gasket respectively, and The sealing function of each strip of paper used for sealing and rock sample is realized by rubber sheet gasket.
Front side strip of paper used for sealing with a thickness of 2 centimetres.
It is a kind of that rock sample reinforcement and repair grouting test is carried out using above-mentioned cube rock sample reinforcement and repair grouting test device Method, method includes the following steps:
Step 1: fixed bracket base being placed on testing stand, then the rock sample to reinforcement and repair is placed on fixed branch Four columns are mounted on fixed bracket upper cover plate by frame pedestal middle position, guarantee each column bottom surface and fixed bracket base Bottom surface is concordant, the mounting and fixing bracket upper cover plate on column, so that fixed bracket upper cover plate covers on the rock sample to reinforcement and repair;
Step 2: horizontal under the appropriate location bonding on each column according to the position of shear surface on the rock sample to reinforcement and repair It to mounting bar and is above transversely mounted item, rock sample fixing bolt passes through down the rock sample for being transversely mounted item and being above transversely mounted on item and fixes Hole simultaneously pushes against rock sample;
Step 3: left side strip of paper used for sealing, right side strip of paper used for sealing and rear side strip of paper used for sealing being fitted together to form an entirety, by the entirety Be installed on each corresponding position of the shear surface of the rock sample to reinforcement and repair, then by the fixed patch of strip of paper used for sealing interface by left side strip of paper used for sealing and Right side strip of paper used for sealing connect both ends connection with the left and right ends of front side strip of paper used for sealing respectively, is filled by upper provisions for grouting fixing bolt and lower grouting It sets fixing bolt rock sample shear surface provisions for grouting is fixed on the shear surface to the rock sample of reinforcement and repair, completes rock sample shear surface The installation of provisions for grouting;
Step 4: by one end cap of grouting hose at inlet pipe, the other end is protruded into the container for filling grouting slurries, will be gone out One end cap of hose is starched on pulp exhaust pipe, the other end protrudes into the container for containing grouting waste liquid, adjusts pressure gauge, beats Micro-high-pressure pump is opened, rock sample shear surface consolidation by grouting test can be carried out.
