Construction method of plastic concrete deep anti-seepage wall crossing strong-leakage collapse-prone backfill stratum
The invention relates to the technical field of water conservancy projects, and discloses a construction method of a plastic concrete deep anti-seepage wall crossing a strong-leakage easily-collapsed backfill stratum. Preparing wall-fixing slurry; measuring and setting out, and constructing a guide wall; pre-filling thick slurry into a backfill layer; forming holes and grooves; cleaning holes and changing slurry; grouting pipes are buried, and guide pipes are poured; and pouring plastic concrete. The backfill layer is pretreated, namely thick slurry is pre-poured, so that the diaphragm wall process can be more efficiently and stably implemented in water and electricity projects under complex conditions, the grooving guarantee rate is greatly improved, and the additional labor, machine and time cost caused by adverse factors such as frequent hole collapse during grooving and incapability of returning slag due to leakage of wall fixing slurry of the strong leakage backfill layer is avoided. And the diaphragm wall slotted hole uses positive electricity glue as a tackifier to prepare bentonite slurry, so that the wall fixing effect is improved.
本发明涉及水利工程技术领域，公开了跨强漏失易坍塌回填地层塑性混凝土深厚防渗墙施工方法，槽段划分；固壁泥浆配置；测量放样及导墙施工；回填层预灌浓浆处理；造孔成槽；清孔换浆；埋设灌浆管及浇筑导管；塑性混凝土浇筑。通过对回填层进行预处理即预灌浓浆，使得防渗墙工艺可以更高效、稳定地在复杂条件水电项目中实施，大大提高了成槽保证率，避免了因成槽时频繁塌孔、强漏失回填层固壁泥浆漏失无法返渣等不利因素额外投入的人工、机械、时间成本。防渗墙槽孔使用正电胶为增粘剂配置膨润土泥浆，以提高固壁效果。
