Thixotropic slurry and pipe jacking construction method based on thixotropic slurry
The invention belongs to the technical field of underground engineering construction, and particularly relates to thixotropic slurry and a pipe jacking construction method based on the thixotropic slurry. The thixotropic slurry comprises the following components: a matrix, a stabilizer, a curing agent, a slow release agent and water, the curing agent comprises a curing agent A and a curing agent B; the curing agent A is at least one of calcium-containing soluble salt, calcium-containing soluble alkali, magnesium-containing soluble salt and magnesium-containing soluble alkali; the curing agent B is salt, a salt solution or gas which can react with the curing agent A to generate insoluble precipitates; and the curing agent B is embedded in the degradable material to form an embedded material which is independent of other components. According to the thixotropic slurry, the lubricating effect of the thixotropic slurry is guaranteed, meanwhile, the thixotropic slurry has the self-hardening function, according to the pipe jacking construction method based on the thixotropic slurry, thixotropic slurry replacement is not needed, the operation process is shortened, and the production cost is reduced.
本发明属于地下工程施工技术领域，具体涉及一种触变泥浆和基于其的顶管顶进施工方法。该触变泥浆包括以下组分：基质、稳定剂、固化剂、缓释剂和水；所述固化剂包括固化剂A和固化剂B；所述固化剂A为含钙元素的可溶性盐、含钙元素的可溶性碱、含镁元素的可溶性盐、含镁元素的可溶性碱中的至少一种；所述固化剂B为能够与固化剂A反应生成不溶性沉淀的盐、盐溶液或气体；所述固化剂B被包埋于可降解材料中形成包埋物，独立于其他组分存在。该触变泥浆，在保证其润滑效果的同时使其具备了自硬化功能，基于该触变泥浆的顶管顶进施工方法，无需进行触变泥浆置换，缩减了操作流程，降低了生产成本。
