Slurry making construction method suitable for tunnel vault grouting site
The invention discloses a construction method suitable for slurrying and grouting at a tunnel vault with a mold, the core is a technology of'grouting agent and field proportioning ', the grouting agent is composed of a plurality of additives, mainly including a plastic expanding agent, a powder water reducer, an expanding agent, a water-retaining agent, an early strength agent, a defoaming agent and other additives, and industrialized production can be carried out. Construction technicians mix cement, sand and water on site with the grouting agent to prepare the grouting material on site, and the grouting material is used for providing the tunnel vault grouting material. According to the technical scheme provided by the invention, the production cost is reduced, the energy consumption is reduced, required admixture bags are all independently packaged, the field debugging difficulty is reduced, the admixture is stirred when being used, the material waste is reduced, and the service life of the material is prolonged; and the required cement, sand, admixture and the like can be directly made of local materials, so that the packaging and transportation cost is greatly reduced, and the economic benefit and the social benefit are remarkable.
本发明公开了适用于隧道拱顶带模制浆注浆施工方法，核心为“注浆剂+现场配料”技术，注浆剂由多种外加剂组成，主要包括塑性膨胀剂、粉体减水剂、膨胀剂、保水剂、早强剂、消泡剂及其他外加剂等，可进行工厂化生产。施工技术人员利用现场的水泥、砂及水与注浆剂进行混合，现场配制成注浆料，用于提供隧道拱顶注浆料。本发明所述的技术方案降低了生产成本，减少能耗，所需外加剂料包均为独立包装，降低了现场调试难度，随用随拌，减少材料浪费，延长材料的使用寿命；所需的水泥、砂、外掺料等可直接利用当地材料，大大降低了包装、运输成本，经济效益和社会效益显著。
