Abstract

The invention discloses a double-liquid grouting device for geotechnical engineering foundation reinforcement. The double-liquid grouting device comprises a shell, two sets of symmetrically-arranged rotating bottom plates are arranged in the shell through material guiding pipelines in a rotationally connected mode, accommodating cavities used for accommodating cement slurry materials and water glass are fixedly formed in the rotating bottom plates, a material pumping structure communicating with the accommodating cavities through material guiding pipelines and intermittently pumping the materials is further fixedly arranged in the shell, the material pumping structure and the material guiding pipelines are driven synchronously by a transmission structure, and a movable upper cover structure used for plugging the accommodating cavities is further arranged at the upper end of the shell in a movably assembled mode. According to the double-liquid grouting device, double-pipe grouting can be formed, according to the optimal material grouting ratio summarized by actual construction, the material grouting mode can ensure that the cement slurry materials and the water glass in the two setsof accommodating cavities are grouted in 1:1, thus the construction quality is ensured, the construction precision is improved, and the more scientific and accurate effects are achieved relative to atraditional mode of controlling the grouting amount.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a double-fluid grouting equipment for geotechnical engineering foundation reinforcement. Background technique [0002] The grouting reinforcement of the foundation pit stratum is to increase the strength, stiffness and impermeability of the soil by means of grouting, so that it can meet the requirements of the foundation pit project. [0003] In the prior art, during grouting, grouting equipment can be used to inject cement and water glass respectively in proportion, which can act in the foundation pit and obtain a reinforcement effect. In the prior art, in order to achieve a fixed injection ratio of cement and water glass, quantitative and constant speed operation is required, and the traditional casing is not easy to use, so it is difficult to achieve consistency between the actual operation effect and the theoretical effect. Contents of the invention [000...
