Tunnel construction double-liquid grouting machine
The invention belongs to the technical field of tunnel construction, and particularly relates to a tunnel construction double-liquid grouting machine which comprises a grouting head, the top end of the grouting head is connected with a first grouting pipe in a penetrating mode, one side of the first grouting pipe is provided with a second grouting pipe, and the second grouting pipe is connected with the grouting head in a penetrating mode. A one-way valve element is fixed to the output end of the second grouting pipe, a transition groove is formed in the grouting head and located outside the one-way valve element, the bottom face of the inner wall of the transition groove is an inclined face, and a mixing groove is formed in the grouting head and located below the first grouting pipe. Through the design that the bottom face of the inner wall of the transition groove is an inclined face, discharging of grout can be more effectively accelerated, the discharged grout has a certain initial speed, and therefore mixing of the two kinds of grout is facilitated, meanwhile, a partition plate is arranged to shield the grout in the first grouting pipe to a certain degree, and the grouting efficiency is improved. The situation that slurry of the first grouting pipe is mixed into the transition groove, and consequently the interior of the transition groove is blocked is prevented to a certain extent.
本发明属于隧道施工技术领域，具体的说是一种隧道施工双液注浆机，包括注浆头，所述注浆头顶端贯通连接有第一注浆管，所述第一注浆管一侧设置有第二注浆管，所述第二注浆管与注浆头贯通连接，所述第二注浆管输出端固定有单向阀芯，所述注浆头内部且位于单向阀芯的外部开设有过渡槽，所述过渡槽内壁的底面为斜面，所述注浆头内部且位于第一注浆管的下方开设有混合槽；通过过渡槽内壁底面为斜面的设计可以更加有效的加速浆液的排出，并使得排出的浆液具备一定的初始速度，从而便于两种浆液的混合，同时设置分隔板可以对第一注浆管内的浆液进行一定的遮挡，一定程度预防了第一注浆管的浆液混入到过渡槽内，造成过渡槽内部出现堵塞的情况。
