摘要：

以深部地下工程的加固和高压突水治理为研究对象，对一种新型化学注浆材料的化学反应封堵机制进行了可行性分析，并针对化学浆液的流动性、渗透性、抗冲刷性以及固结体的强度、水质毒理等因素进行了室内试验研究，详细地分析了浆液的物理化学特征，给出了浆液最佳配比值以及相应的性能指标。结合高压突水工程实例，开展现场注浆封堵试验，检验浆材用于突水封堵治理的可行性，并与超细水泥、水泥-水玻璃、尿醛树脂等常见注浆材料的封堵效果进行对比。试验结果表明：该化学浆液具有反应块、强度高、抗冲刷性强、无毒以及良好的渗透性和遇水膨胀功能，在现场应用中表现出良好的可控性和可泵性以及理想的注浆效果，与水泥类和一些常用化学浆材相比，具有运输快捷、配料方便、工艺简单的优点，所得结论对后续研究具有重要借鉴意义。

Abstract:

In order to resolve the treatment of inrush of high-pressure water and reinforcement in deep underground engineering, combined with the reinforcement mechanism research of chemical grouting material, not only the feasibility of a new type of chemical grout has been studied, but also the experimental research on properties of new types of chemical grout, such as mobility, penetrability, strength, anti-brushing performance, water genotoxicity and so on are performed in the laboratory; therefore the physicochemical characteristics of has been analyzed; the proper proportion of new chemical grout and its relative specifications have been given. In addition, based on a project case under water-inrush hazard, the field experiment has also been carried out; contrasted to other types of grout, such as cement with super fine slag, cement and water glass double grouts, and urea resin harnstoffharz, the applications and advantages of this chemical grout on inrush of high-pressure water controlling has further been proved. It is shown that this new chemical grout is quick reaction, high strength, well scouring resistance, innocuous and excellent performance of permeability and hydro-expansiveness. Ideal grouting effect has been reached for its good controllability and pumpability in the field test, contrasted to the styles of cement grouting material and some common chemical grout material, it has advantages of rapid transportation, convenient proportioning and simple technology; the conclusions obtained will devote to the following studies.

Key words: reinforcement, grouting material, grouting mechanism for waterproof, laboratory test, field test
