Construction method of impervious concrete horizontal construction joint
The invention relates to the technical field of construction, in particular to a construction method of an impervious concrete horizontal construction joint, which comprises the following steps: pouring lower-layer three-graded concrete; chiseling or flushing on the horizontal plane; pouring second-grade rich slurry concrete for 3d-5d, wherein the strength grade of the second-grade rich slurry concrete is the same as that of the third-grade concrete; and pouring the upper-layer three-graded concrete. According to the method, the second-level mixed slurry-rich concrete is poured at the horizontal construction joint of the three-level mixed concrete which is poured in a layered mode, pores of the three-level mixed concrete on the lower layer are filled and compacted, and therefore the anti-seepage grade of the horizontal construction joint reaches the W5 grade, the three-level mixed concrete on the upper layer is poured together with the second-level mixed slurry-rich concrete, boundaries of the two are mutually fused, and the anti-seepage performance of the horizontal construction joint is improved. The concrete can be regarded as integral concrete, the anti-permeability grade can reach the W6 grade of a concrete body, it means that the anti-permeability grade of the concrete poured in a layered mode is at least the W5 grade and is far higher than the W1 grade of the concrete poured on the lower-layer three-graded concrete directly, and the anti-permeability performance of the horizontal construction joint is improved.
本发明涉及施工技术领域，是一种抗渗混凝土水平施工缝的施工方法，包括浇筑下层三级配混凝土；水平面凿毛或冲毛；3d‑5d浇筑二级配富浆混凝土，强度等级与三级配混凝土强度等级相同；紧接浇筑上层三级配混凝土。本发明通过在分层浇筑的三级配混凝土的水平施工缝处浇筑二级配富浆混凝土，填充密实下层三级配混凝土的孔隙，从而提高水平施工缝的抗渗等级达到W5级，而上层三级配混凝土紧接二级配富浆混凝土一同浇筑，两者界限相互交融，可视为整体混凝土，抗渗等级能够达到混凝土本体的W6级，意味着分层浇筑的混凝土的抗渗等级至少为W5级，远高于直接在下层三级配混凝土上浇筑上层三级配混凝土的W1级的抗渗等级，提高水平施工缝的抗渗性能。
