Full-section prefabricated immersed tube concrete anti-crack construction method
The invention discloses a full-section prefabricated immersed tube concrete anti-cracking construction method, and belongs to the technical field of concrete anti-cracking. Comprising the following steps that in the full-section prefabricated immersed tube steel bar binding process, a chiseling-free steel bar net is used for conducting longitudinal binding in the direction of a traffic lane of a prefabricated immersed tube so that a bottom plate, side walls, a middle partition wall and a top plate of the prefabricated immersed tube can be divided into a plurality of common pouring areas and regulation and control pouring areas, the wall thickness of the regulation and control pouring area is greater than that of the adjacent common pouring area; temperature stress meters used for monitoring temperature monitoring data in concrete in real time are embedded in the multiple common pouring areas and the regulation and control pouring areas of the prefabricated immersed tube respectively; and when concrete is poured into the prefabricated immersed tube, concrete doped with a hydration heat regulation and control material is poured into the regulation and control pouring area, concrete with a common mixing proportion is synchronously poured into the adjacent common pouring area, and after the overall pouring of the prefabricated immersed tube is completed, corresponding curing measures are taken according to temperature monitoring data obtained by the temperature stress meter in real time.
本发明公开了一种全断面预制沉管混凝土抗裂施工方法，属于混凝土抗裂技术领域，包括如下方法步骤：在全断面预制沉管钢筋绑扎过程中用免凿毛钢筋网沿预制沉管的行车道方向纵向绑扎以使预制沉管的底板、侧墙、中隔墙和顶板分割成若干个普通浇筑区和调控浇筑区，其中，调控浇筑区的墙体厚度大于相邻普通浇筑区的墙体厚度；在预制沉管的若干个普通浇筑区和调控浇筑区中分别埋设用于实时监测混凝土内部温度监测数据的温度应力计；预制沉管浇筑混凝土时，在所述调控浇筑区浇筑掺有水化热调控材料的混凝土，并同步在相邻所述普通浇筑区浇筑普通配合比混凝土，待预制沉管整体浇筑完成后，根据所述温度应力计实时获取的温度监测数据进行相应养护措施。
