The invention discloses a production process of tunnel sprayed concrete, whch belongs to the technical field of concrete production. The production process comprises the following steps of S1, preparing materials, S2, preparing materials, S3, weighing the materials according to the proportion for later use, S4, preparing a primary mixed material, S5, preparing a mixture, and S6, preparing sprayed concrete. According to the tunnel sprayed concrete disclosed by the invention, the water reducing agent, the accelerator, the early strength agent and the WS anti-seepage additive are sequentially added in the mixing process of adding clear water into the primary mixture, and the water reducing agent can improve the strength of the concrete and reduce the subsequent use amount of the accelerator, the early strength agent and the WS anti-seepage additive at the same time, so that the production cost of the tunnel sprayed concrete is reduced; the accelerator can accelerate the setting speed of the tunnel sprayed concrete, the early strength agent can improve the early strength of the tunnel sprayed concrete, the WS anti-seepage additive can improve the compactness and impermeability of the tunnel sprayed concrete, and the addition of various additives can improve the overall quality of the tunnel sprayed concrete, thereby improving the quality of tunnel construction.
本发明公开了一种隧道喷射混凝土的生产工艺，属于混凝土生产技术领域，包括以下步骤：S1：制备材料；S2：准备材料；S3：按照比例称量材料，备用；S4：制初混料；S5：制混合料；S6：制喷射混凝土；本发明隧道喷射混凝土在初混料加清水搅拌过程中依次添加减水剂、速凝剂、早强剂和WS抗渗添加剂，减水剂能够提高混凝土强度的同时减少后续速凝剂、早强剂和WS抗渗添加剂使用量，降低隧道喷射混凝土生产成本，速凝剂能够加快隧道喷射混凝土凝结速度，早强剂能够提高隧道喷射混凝土早期强度，WS抗渗添加剂能够提高隧道喷射混凝土密实度和抗渗性，多种外加剂的添加，能够提高隧道喷射混凝土整体的质量，从而提高隧道施工的质量。
