Background
Grouting is a construction method for improving the self performance of a reinforced rock mass, and is generally used for building engineering, mine engineering, hydraulic engineering, tunnel engineering and the like. The essence of grouting is that grouting equipment is used for injecting prepared grout into a rock mass needing grouting through a preset grouting pipeline, so that the grout permeates into cracks and cavities of the broken surrounding rocks and is solidified to form an integral structure with the broken surrounding rocks, and the cohesion and the tensile strength of the broken surrounding rocks can be obviously improved. On one hand, the broken surrounding rock is transformed from a complete load body into a structural body with certain bearing capacity after grouting, so that the stress of the supporting structure is reduced; on the other hand, for the passive supporting mode, the grouting and filling enable the supporting structure to be stressed uniformly, and the full exertion of the supporting capacity is facilitated. For the anchor rod support, grouting can improve the acting foundation of the anchor rod support, is beneficial to exerting the advantages of the anchor rod support, and effectively limits the loosening and deformation of surrounding rocks, thereby playing a role in stabilizing a reinforced structure.
The degree to which the pores and cracks are filled with grout is called the grout saturation, and generally the greater the saturation, the higher the strength of the injected medium. In engineering operation, grouting generally adopts a quantitative injection method, so that slurry in a stratum often has certain fluidity after grouting is finished, and therefore, the slurry can continuously run off towards the front edge under the action of gravity, so that holes which are originally filled are re-hollow, namely, the filling is unsaturated, and the overall strength of the grouted slurry is weakened. Therefore, unsaturated filling is a common problem in grouting engineering, great hidden danger is brought to the engineering, and cavities generated by unsaturated grouting in concrete are difficult in the construction process all the time. In addition, the grouting saturation directly influences the service life and the safety risk of the engineering construction, so that the economic loss and the social influence caused by the grouting saturation are huge.
Consequently, now lack a grout saturation intellectual detection system, simple structure, reasonable in design realizes the detection of the different degree of depth grouting pressure, is convenient for accurately judge the grout saturation, ensures the construction quality of being in a milk.
