The invention relates to the technical field of grouting machines, and provides a high-pressure jet grouting device for civil engineering, comprising a grouting pipe head provided with a plurality of first grouting ports; the reinforcing pipe head is provided with a plurality of second grouting openings and a plurality of reinforcing holes, the grouting pipe head is sleeved with the reinforcing pipe head, a mounting space is formed between the reinforcing pipe head and the grouting pipe head, and the reinforcing holes are located in the two sides of the second grouting openings; one end of each connecting channel communicates with the first grouting opening, and the other end of each connecting channel communicates with the second grouting opening; the first moving part is movably arranged on the reinforcing pipe head and located outside the installation space. By means of the technical scheme, the problems that in the prior art, when high-pressure grout and airflow are used for cutting and drilling holes, the cutting force cannot be adjusted when cutting and grouting are conducted on different soil bodies under the same geology, and meanwhile when a drill rod is used for drilling holes, broken stone is prone to being clamped in gaps of drilling tools, and further drilling is affected are solved.
本发明涉及注浆机技术领域，提出了一种土木工程用高压喷射注浆装置，包括注浆管头，具有若干个第一注浆口；加强管头，具有若干个第二注浆口和若干个加强孔，加强管头套设在注浆管头外，加强管头和注浆管头之间具有安装空间，加强孔位于第二注浆口两侧；连接通道，具有若干个，连接通道一端连通第一注浆口，另一端连通第二注浆口；第一移动件，移动设置在加强管头上，且位于安装空间外。通过上述技术方案，解决了现有技术中的高压浆液和气流切割钻孔时对于同一地质下的不同土体在切割注浆时，无法调节切割力，同时钻杆在钻孔时，打碎的碎石，容易卡接在钻刀的间隙处，影响进一步打孔问题。
