Post-cast strip structure and construction method thereof
The invention provides a post-cast strip structure. The post-cast strip structure comprises concrete bottom plates and a post-cast strip, wherein the concrete bottom plates are located on the two sides of the post-cast strip, a corrugated formwork is arranged between the concrete bottom plates and the post-cast strip, a horizontal water stop belt is arranged in the middle of the formwork in a penetrating mode, and the two ends of the water stop belt extend into the concrete bottom plates and the post-cast strip respectively. The post-cast strip structure further comprises a plurality of joint bars and expansion water stop bars, wherein the joint bars penetrate through the post-cast strip, the two ends of each joint bar extend into the corresponding concrete bottom plate, and the expansion water stop bars are arranged in the post-cast strip. The invention further provides a construction method of the post-cast strip structure. By the adoption of the post-cast strip structure and the construction method, the number of construction procedures is small, the process is simple, the overall structural rigidity of the concrete bottom plates is high, the anti-seepage performance of the bottom plate structure is good, cracks and shrinkage deformation are not prone to occurring, and the overall construction quality of a spillway bottom plate and an upper structure of a hydropower station reaches the excellent level.
本发明提供了一种后浇带结构，包括混凝土底板和后浇带，所述混凝土底板位于所述后浇带的两侧，所述混凝土底板和后浇带之间设有呈波纹状的模板，所述模板的中部穿设有水平的止水带，所述止水带的两端分别延伸至所述混凝土底板和后浇带中；还包括多根插筋和膨胀止水条，所述插筋贯穿所述后浇带，其两端分别延伸至所述混凝土底板中，所述膨胀止水条设置在所述后浇带中。本发明还提供了一种前述的后浇带结构的施工方法。采用本发明的后浇带结构和施工方法，施工工序少、工艺简单，混凝土底板整体结构刚度高，底板结构防渗性能好，不易出现裂缝及收缩变形，可确保水电站溢洪道底板及上部结构整体施工质量达到优良水准。
