Method for determining slurry ratio of large-diameter shield tunnel synchronous grouting double slurry
The technical problem to be solved by the invention is to provide the large-diameter shield tunnel synchronous grouting double-liquid slurry proportion determination method, a reference proportion is determined through early-stage investigation and survey, different water cement ratios and a volume ratio test of liquid A and liquid B are designed, an influence rule on the slurry performance is determined, and through an on-site construction test, a large-diameter shield tunnel synchronous grouting double-liquid slurry proportion determination result is obtained. The method is based on the construction site requirement, the slurry proportion can be scientifically adjusted, and the method can be popularized and used in shield tunnel construction.
本发明要解决的技术问题是提供一种大直径盾构隧道同步注浆双液浆浆液配比确定方法，经过前期调研确定基准配比，并设计不同水灰比和A液与B液体积比试验，明确其对浆液性能影响规律，通过现场施工试验，对管片上浮和管片环缝错台反馈，确定最终浆液配比，该方法既基于施工现场需求，又可科学对浆液配比进行调整，可在盾构隧道建设中推广使用。
