Constructional engineering complex foundation grouting equipment

LIU GUOQIANG / CHEN HONG

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.

本发明公开了一种建筑工程复杂地基注浆设备，涉及地基注浆技术领域，包括：底座；注浆管，穿射于所述底座且伸入地层中；双液双压注浆组件，具有第一注浆管、第二注浆管以及一出液端，所述第一注浆管、第二注浆管中的浆液成分不同，所述出液端与注浆管相连通；以及供浆组件，其能够为所述双液双压供浆组件进行分别供浆，且所述第二注浆管与所述供浆组件之间设置有脉冲供浆组件，以便以脉冲形式提高注浆压力；且注浆时，先由所述第一注浆管以第一注浆压力进行注浆；之后由第二注浆管以第二注浆压力进行注浆，从而提高了注浆效果。
