Construction method for crack resistance of plateau tunnel lining concrete
The invention belongs to the technical field of tunnel construction, and relates to a construction method for crack resistance of plateau tunnel lining concrete, which comprises the following steps: S1, screening of concrete raw materials: screening all raw materials according to the requirements of crack resistance of plateau tunnel lining concrete and the following requirements; s2, according to the anti-cracking performance requirement of the plateau tunnel lining concrete, the raw materials screened in the step S1 are adopted, and anti-cracking concrete is formed according to the set mixing proportion; s3, preparation before concrete pouring; s4, the concrete is put into a mold, poured and vibrated; and S5, concrete curing. According to the method, the concrete mixing proportion is designed, the concrete is poured in a mold, and the vibration and curing temperature and humidity in the concrete pouring process are controlled, so that the concrete shrinkage rate is reduced, and the anti-cracking performance of the concrete is improved.
本发明属于隧道施工技术领域，涉及一种用于高原隧道衬砌混凝土抗裂的施工方法，包括以下步骤：S1、混凝土原材料筛选：根据高原隧道衬砌混凝土抗裂性能要求，按照以下要求筛选各个原材料；S2、根据高原隧道衬砌混凝土抗裂性能要求，采用步骤S1筛选的原材料并按照设定的配合比形成抗裂混凝土；S3、混凝土浇筑前准备；S4、混凝土入模、浇筑、振捣；S5、混凝土养护。本发明通过设计混凝土配合比、混凝土入模浇筑、控制混凝土浇筑中振捣及养护温湿度，使得混凝土收缩率降低，提高混凝土的抗裂性能。
