Construction method of diversion trench refractory concrete junction surface
The invention provides a construction method of a diversion trench refractory concrete junction surface. The construction method of a diversion trench refractory concrete junction surface comprises the following steps that when a main body structure is constructed, an inverted trapezoidal batten is arranged on the upper side surface of a bottom die of a main body structure template; after the main body structure template is reinforced, joint bars are inserted into the bottom die, and concrete pouring is conducted; after the template is removed, the trapezoidal battens are removed, and a trapezoidal groove is formed in the bottom face of the main body structure; steel bars of a refractory concrete layer are bond on the joint bars; and after steel bars of the refractory concrete layer are bound, layered spraying construction is conducted on the lower portion of the main body structure through a concrete spraying machine, and the refractory concrete layer is formed. The method has the beneficial effects that the groove is reserved in the main body structure, so that the mechanical occlusal force of the concrete is enhanced, and the bonding effect of main body concrete and post-pouring refractory concrete is improved.
本发明提出了一种导流槽耐火混凝土结合面的施工方法，包括：进行主体结构施工时，在主体结构模板的底模上侧面设置倒梯形木条；在主体结构模板加固完成后，在底模上插设插筋，并进行混凝土浇筑；拆模后，剔除梯形木条，在主体结构底面上形成梯形沟槽；在插筋上绑扎耐火混凝土层的钢筋；在耐火混凝土层的钢筋绑扎完成后，在主体结构的下部，通过混凝土喷射机分层喷射施工，以形成耐火混凝土层。本发明的有益效果在于，本发明采用在主体结构上预留沟槽，增强了混凝土机械咬合力，提高了主体混凝土和后浇筑耐火混凝土粘结效果。
