Method for preparing post-wall grouting material by utilizing waste amphibole muck through earth pressure shield
The invention relates to a method for preparing a post-wall grouting material by utilizing waste amphibole muck through earth pressure shield. The method comprises the following steps: (1) cleaning and drying muck discharged during shield excavation of a amphibole stratum; (2) conveying the muck treated in the step (1) to a screening machine for screening to remove large particles; and (3) replacing part of medium sand in the original post-wall grouting material with the sieved muck, and then adding bentonite, fly ash, cement and water to prepare the post-wall grouting material. The grouting material comprises cement, coal ash, bentonite and screened muck, the treated muck replaces part of river sand in traditional materials, the problem that sand in the Jinan area is difficult to purchaseis solved, and the muck recycling process method is economical and environmentally friendly.
本发明涉及一种土压盾构利用废弃闪长岩渣土配制壁后注浆材料方法，包括以下步骤：（1）将闪长岩地层盾构开挖时排出的渣土进行清洗、烘干；（2）将经过步骤（1）处理的渣土送至筛分机进行筛分，去除大颗粒；（3）将过筛后的渣土替代部分原壁后注浆材料中的中砂，再加入膨润土、粉煤灰、水泥和水制成壁后注浆材料。本发明的注浆材料包括水泥、粉煤灰、膨润土、经过筛分的渣土，其中经过处理的渣土替代了部分传统材料中的河砂，解决了济南地区中砂采购困难的问题，是一种既经济又环保的渣土再利用的工艺方法。
