Abstract

The invention discloses an unconsolidated formation grouting experimental device. The unconsolidated formation grouting experimental device comprises a grouting machine tool, a grouted body container (18), a water pressure control system, a confining pressure system and a monitoring system. The grouting machine tool is communicated into an accommodating cavity of the grouted body container (18); the water pressure control system is communicated into the accommodating cavity of the grouted body container (18) through a conveying pipeline (14); the confining pressure system comprises a pressure source gas cylinder (10), a gas pipe (12) and a high-pressure gas bag (17) arranged in the grouted body container (18), and the high-pressure gas bag (17) after gas filling is attached to the inner wall of the grouted body container (18); and the monitoring system comprises an external information collection device (21) and a pressure sensor (19) arranged in the grouted body container (18), and the information collection device (21) is connected with the pressure sensor (19) through a connecting wire (22). The unconsolidated formation grouting experimental device disclosed by the invention has the advantages of simple structure, convenience in assembly, easiness in measurement operation, accurate and reliable test results, wide range of applications and the like.

Description

technical field [0001] The invention relates to a grouting experimental device which can be widely used in the fields of water conservancy engineering, mining engineering, geological engineering, foundation treatment and the like, and in particular relates to a loose stratum grouting experimental device. Background technique [0002] Grouting is an engineering measure with strong practicability and a wide range of applications. However, due to the complexity of the grouted body and the high concealment of engineering implementation, the design of grouting parameters and the inspection of grouting effects are extremely empirical. In particular, the characteristics of heterogeneity and anisotropy are very significant for loose overburden layers, weak interlayer layers, dissolution (fault) layers, and deep dense sand-bearing layers, etc. It is difficult to implement grouting control and achieve uniform grouting for anti-seepage and reinforcement grouting. In the current grouti...
