Manufacturing method of tunnel sprayed concrete
The invention relates to the technical field of sprayed concrete, and particularly discloses a manufacturing method of tunnel sprayed concrete, which comprises the following steps: S1, sequentially adding coarse aggregate, part of fine aggregate and cement into a stirrer, and uniformly stirring; gradually adding the residual fine aggregate, the active additive, the water and the water reducing agent in batches in the stirring process, and uniformly stirring to obtain a coarse sprayed concrete mixture; s2, adding a catalyst and an accelerator into the rough sprayed concrete mixture, and stirring for 2-3 minutes to obtain a sprayed concrete mixture; and S3, spraying the sprayed concrete mixture on the surface of the tunnel rock surface, and solidifying to obtain the tunnel sprayed concrete.
本发明涉及喷射混凝土技术领域，具体公开了一种隧道喷射混凝土的制作方法，包括以下步骤：S1：在搅拌机中依次加入粗集料、部分细集料和水泥搅拌均匀；然后在搅拌过程中，逐步分批加入剩余细集料、活性添加剂、水和减水剂，搅拌均匀，得到粗制喷射混凝土拌合物；S2：在上述粗制喷射混凝土拌合物中加入催化剂、速凝剂，搅拌2～3分钟，得到喷射混凝土拌合物；S3：将喷射混凝土拌合物喷涂在隧道岩面表面，凝固，得到隧道喷射混凝土。
