Constructional engineering complex foundation grouting equipment

Abstract

The invention discloses constructional engineering complex foundation grouting equipment, and relates to the technical field of foundation grouting. The constructional engineering complex foundation grouting equipment comprises a base, a grouting pipe, a double-liquid double-pressure grouting assembly and a slurry supply assembly, and the grouting pipe penetrates through the base and extends into the stratum; the double-liquid double-pressure grouting assembly is provided with a first grouting pipe, a second grouting pipe and a liquid outlet end, grout components in the first grouting pipe and the second grouting pipe are different, and the liquid outlet end communicates with the grouting pipes; and the slurry supply assembly can supply slurry to the double-liquid double-pressure slurry supply assembly, and a pulse slurry supply assembly is arranged between the second grouting pipe and the slurry supply assembly so that the grouting pressure can be increased in a pulse mode. In the grouting process, grouting is carried out through the first grouting pipe at the first grouting pressure; and then, the second grouting pipe is used for grouting at the second grouting pressure, so that the grouting effect is improved.

Description

technical field [0001] The invention relates to the technical field of foundation grouting, in particular to complex foundation grouting equipment for construction engineering. Background technique [0002] In construction engineering, the weight of buildings basically needs to be carried by foundations. Natural foundations can be used when the geological conditions of the soil layer are good; For geology, artificial reinforcement of the foundation is required. Among them, foundation grouting is a common method of foundation reinforcement. During construction, holes are drilled at the designated position of the foundation, and then the prepared grout is injected into the formation through the grouting pipe. , combined with the soil, thereby improving the strength of the soil, but the existing grouting equipment has low grouting efficiency, and it is difficult to penetrate the grout into the tiny pores in the formation to combine with the soil, and the grouting effect is poor...
