Coastal region shield tunnel synchronous grouting material and preparation method thereof
The invention discloses a synchronous grouting material for a shield tunnel in a coastal region and a preparation method thereof, and the synchronous grouting material for the shield tunnel in the coastal region comprises the following raw materials in parts by weight: 20-40 parts of cement, 10-25 parts of steel slag powder, 80-120 parts of shield muck, 15-35 parts of phosphogypsum, 120-150 parts of unpurified sea sand, 4-6 parts of an early strength agent, 1-3 parts of a conditioner and 100-125 parts of mixing water. Wherein the use amount of the shield muck is calculated according to the mass without water, and the use amount of the mixing water contains the water content in the shield muck; coastal resources and the muck generated by shield construction are fully utilized as raw materials, other raw materials are used in a matched mode, the use amount of cement and river sand is greatly reduced, the building muck is consumed, and therefore the cost is reduced, and green and low-carbon production of the synchronous grouting material is achieved.
本发明公开了一种沿海地区盾构隧道同步注浆材料及其制备方法，述沿海地区盾构隧道同步注浆材料包括以下重量份的原料：水泥20‑40份、钢渣粉10‑25份、盾构渣土80‑120份、磷石膏15‑35份、未净化海砂120‑150份、早强剂4‑6份，调理剂1‑3份，拌合水100‑125份，其中盾构渣土的用量以不含水质量计，拌合水的用量包含了盾构渣土中的含水量；本发明充分利用沿海资源和盾构施工所产生的渣土为原料，配合其他原料的使用，大幅降低水泥、河砂用量，消纳建筑渣土，从而降低成本，实现同步注浆材料的绿色化、低碳化生产。
