Filling type injection material and process for water leakage and sand leakage plugging emergency rescue
The invention belongs to the technical field of tunnel emergency rescue, and discloses a filling type injection material and process for water leakage and sand leakage plugging emergency rescue. Macromolecule water-absorbent resin particles, water, ordinary Portland cement and water glass are prepared; the high-molecular water-absorbent resin particles pre-absorb water, so that the injection property is realized; the preparation method comprises the following steps: preparing ordinary Portland cement into a cement solution, and preparing the cement solution and water glass into cement-water glass double-liquid slurry; a mixture of high-molecular water-absorbent resin particles and water is injected into the leakage holes, after the high-molecular water-absorbent resin particles absorb water and expand and the leakage water flow is reduced to be stable, cement and water glass double-liquid slurry is injected into the leakage holes, and after the cement and water glass double-liquid slurry is condensed, the leakage holes are completely blocked. According to the method, a mixture of the super absorbent polymer (SAP) and the cement-water glass double-liquid slurry is utilized, the SAP material is firstly injected into a water leakage place, then the cement-water glass double-liquid slurry is injected, and through experimental research, the leaking stoppage effect of the method is superior to that of a traditional double-liquid slurry plug.
本发明属于隧道抢险技术领域，公开了一种用于漏水漏砂封堵抢险的填充式注入材料和工艺，准备高分子吸水树脂颗粒，水，普通硅酸盐水泥，水玻璃；通过高分子吸水树脂颗粒预吸水使其具有可注性；将普通硅酸盐水泥配置为水泥溶液后，将水泥溶液与水玻璃配置为水泥水玻璃双液浆；将高分子吸水树脂颗粒与水的混合物注入渗漏空洞，待高分子吸水树脂颗粒吸水膨胀并使渗漏水流量减小直至稳定后，将水泥水玻璃双液浆注入渗漏空洞，水泥水玻璃双液浆凝结后将渗漏空洞完全封堵。本发明利用高分子吸水树脂(SAP)与水泥水玻璃双液浆混合物，在渗漏水的地方先注入SAP材料，然后再注入水泥水玻璃双液浆，经试验研究，本发明堵漏效果优于传统的双液浆堵。
