Filling type injection material and process for tunnel water leakage and sand leakage emergency rescue
The invention belongs to the technical field of new materials for tunnel emergency rescue, and particularly relates to a filling type injection material and process for tunnel water leakage and sand leakage emergency rescue. In a filling type injection material, the polymer water-absorbent resin particles pre-absorb water to enable the polymer water-absorbent resin particles to have injectability; preparing Portland cement into cement slurry, and uniformly mixing the cement slurry with the super absorbent polymer which pre-absorbs water to obtain SAP cement slurry; and then the grouting body and the water glass are injected into the erosion cavity together, the erosion cavity can be completely blocked after the grouting body is condensed, and the cement in the grouting body uniformly wraps the high-molecular water-absorbent resin, so that the cement and the high-molecular water-absorbent resin form a structural whole. According to the invention, the high-molecular water-absorbent resin and the cement slurry are uniformly mixed and then are injected into the erosion cavity together with the water glass; while erosion holes are blocked, certain pressure can be borne, a tunnel is supported, and uneven settlement of the tunnel is prevented; the slurry preparation method is simple, the time required by the grouting process is short, and the formed grouting body can play roles in plugging leakage water and bearing load at the same time.
本发明属于隧道抢险新材料技术领域，具体涉及一种用于隧道漏水漏砂抢险的填充式注入材料和工艺。填充式注入材料中，先通过高分子吸水树脂颗粒预吸水使其具有可注性；将硅酸盐水泥配置为水泥浆液后，与预吸水后的高分子吸水树脂均匀混合，得到SAP水泥浆液；随后将其与水玻璃一同注入侵蚀空洞，注浆体凝结后即可将侵蚀空洞完全封堵，且注浆体中水泥均匀包裹高分子吸水树脂，二者形成结构性整体。本发明利用高分子吸水树脂与水泥浆液均匀混合后再与水玻璃一同注入侵蚀空洞；在封堵侵蚀空洞的同时，可以承担一定的压力，承托隧道，防止隧道不均匀沉降；浆液配置方法简单，注浆过程所需时间短，成型后的注浆体能同时发挥封堵渗漏水和承担荷载的作用。
