Tunnel anchoring grouting material and preparation method thereof
The invention discloses a tunnel anchoring grouting material and a preparation method thereof, and belongs to the technical field of open joint grouting materials. The tunnel anchoring grouting material is prepared from the following raw materials in parts by weight: 410 to 530 parts of cement, 30 to 50 parts of fine aggregate, 10 to 25 parts of coarse aggregate, 100 to 200 parts of quartz sand, 40 to 75 parts of expanding agent, 3 to 5 parts of polycarboxylic acid early strength type water reducing agent, 1 to 3 parts of slow release agent, 2 to 10 parts of reinforcing agent, 2 to 10 parts of filling agent, 2 to 5 parts of modified flowable agent, 1.5 to 3 parts of hybrid fiber, 0.1 to 1 part of dispersing agent and 1 to 5 parts of defoaming agent. The invention also discloses a preparation method of the tunnel anchoring grouting material which is prepared by uniformly mixing the raw materials according to the steps. The tunnel anchoring grouting material provided by the invention has a relatively good anti-cracking effect, is high in water seepage prevention capacity, is not easy to crack, damage, sink, frost boiling and mud discharging after being quickly condensed, and is relatively long in service life.
本发明公开了一种隧道锚固灌浆料及其制备方法，属于离缝灌浆料技术领域。公开了一种隧道锚固灌浆料，以重量份数计包括以下原料：水泥410‑530份、细骨料30‑50份、粗骨料10‑25份、石英砂100‑200份、膨胀剂40‑75份、聚羧酸早强型减水剂3‑5份、缓释剂1‑3份、补强剂2‑10份、填充剂2‑10份、改性流动剂2‑5份、混杂纤维1.5‑3份、分散剂0.1‑1份、消泡剂1‑5份；还公开了将各原料按照步骤混合均匀的隧道锚固灌浆料的制备方法。本发明提供的隧道锚固灌浆料具有较好的抗开裂效果，防渗水能力强，在快速凝结后不易开裂、破损、下陷、翻浆冒泥等现象，使用寿命较长。
