摘要：

为解决传统黄土防灭火浆体易沉降、堵管路、堆积失效的工程难题,提升稠化浆体悬浮稳定性,对黄土颗粒开展力学分析,探明搅拌时间、搅拌速度、颗粒粒径通过改变颗粒间作用力影响悬浮特性;结合极差、方差、回归及响应面分析,明确因素主次、最优参数区间,并通过现场注浆监测验证参数实用性。研究结果表明:浆体搅拌时间A和浆体搅拌速度B会使稠化浆体剪切稀化,从而改变稠化浆体三维网状结构及分子间的缠结作用;黄土颗粒大小C会影响黄土颗粒在浆体中的比表面积、力学作用和聚团行为,三者共同影响浆体稠度和悬浮性能;A为5 min,B为1 000 r/min,C为140目时,稠化浆体静态悬浮率最优,达到82.5%;各因素对静态悬浮率δ影响的主次排序为B>A>C,搅拌速度是影响稠化浆体静态悬浮率的重要因素;影响稠化浆体材料悬浮效果的因素最优范围为4.3 min≤A≤5.9 min、B=1 000 r/min、108目≤C≤167目,分析结果与极差方差分析结果基本一致;现场注浆过程中的监测及注浆结果验证了实验室得出的最优制备参数对于现场注浆效果具有较好的指导作用。

Abstract:

To address the engineering problems of traditional loess fire-extinguishing slurry, such as easy sedimentation, pipeline blockage and accumulation failure, and improve the suspension stability of thickened slurry, mechanical analysis of loess particles was carried out to derive the settling velocity formula. It was clarified that stirring time, stirring speed and particle size affect suspension characteristics by changing the interaction forces between particles. Combined with range analysis, variance analysis, regression analysis and response surface analysis, the priority of influencing factors and the optimal parameter range were determined, and the practicability of the parameters was verified through on-site grouting monitoring. The results show that the stirring time of slurry A and the stirring speed of slurry B can cause shear thinning of the thickened slurry, thereby changing its three-dimensional network structure and intermolecular entanglement; the size of loess particles C will affect their specific surface area, mechanical effects, and agglomeration behavior in the slurry. These three factors together affect the consistency and suspension performance of the slurry. The static suspension rate of the thickened slurry reaches the optimal level of 82.5% when A is 5 min, B is 1000 r/min, and C is 140 mesh. The primary and secondary ranking of each factor on the static suspension rate δ is B>A>C, indicating that stirring speed is a key factor affecting the static suspension rate of thickened slurry. The optimal ranges of factors influencing the suspension effect of thickened slurry materials are determined as 4.3 min ≤ A ≤ 5.9 min, B = 1000 r/min and 108 mesh ≤ C ≤ 167 mesh. The analysis results are basically consistent with those of range and variance analysis, which verifies the validity of the range and variance analysis results. Field grouting test results verify that the optimal preparation parameters obtained from laboratory experiments provide reliable guidance for on-site grouting performance.

Key words: on-site preparation, fire prevention and extinguishing, thickened slurry, suspension performance, response surface, static suspension rate, on-site factors
