Synchronous grouting slurry for shield construction of different stratums
The invention provides synchronous grouting slurry for shield construction of different stratums. The synchronous grouting slurry is prepared from the following components in parts by weight: 100 to 200 parts of cement, 50 to 650 parts of bentonite, 200 to 900 parts of sand and 300 to 500 parts of water. According to the method, the mix proportion of synchronous grouting slurry for different stratums is provided in a targeted mode, ground subsidence can be controlled within the standard requirement range, and the method has an auxiliary effect on posture adjustment of the shield tunneling machine; the quality of tunnel forming segments is improved, and the occurrence frequency of segment defects is reduced; and the requirements of diffusion velocity, area, final setting time, strength and the like of different stratum properties can be met.
本发明提供一种不同地层盾构施工同步注浆浆液，将水泥、膨润土、砂和水按照如下的重量配比配制：水泥100‑200份、膨润土50‑650份、砂200‑900份，水300‑500份。本发明有针对性地提出应对不同地层的同步注浆浆液的配合比，有利于将地面沉降控制在规范要求范围内，对盾构机姿态调整有辅助作用；有利于提高隧道成型管片质量，降低管片缺陷出现频次；有利于满足不同地层性质扩散速度，面积、终凝时间、强度等要求。
