Construction process for ultrahigh and ultra-thick pool wall of sewage treatment plant
The invention provides a sewage treatment plant ultra-high and ultra-thick pool wall construction technology, and relates to the technical field of sewage treatment, and the technology comprises the following steps: S1, positioning measurement; s2, earth excavation is conducted; s3, supporting the foundation pit; s4, cleaning a bottom layer; s5, pool wall pouring is conducted, specifically, the pool wall is divided into a plurality of pouring areas with the same height according to the height, and the pouring areas are divided into a left pouring area, a middle pouring area and a right pouring area in the longitudinal direction according to the thickness of the pool wall; s6, the formwork is dismantled; s7, surface treatment; and S8, backfilling the foundation pit. The left pouring area and the right pouring area are firstly poured, so that the prefabricated formwork is fixedly connected with the pouring area and the right pouring area, then concrete pouring in the middle pouring area is conducted, and the solidification period of super-thick concrete is shortened by conducting regional pouring on pool wall concrete; and meanwhile, the probability that cavities are formed after the concrete is solidified due to non-uniform vibration during concrete pouring is reduced, and the difficulty of super-thick concrete during formwork laying is also reduced due to partitioned pouring.
本发明提供污水处理厂超高超厚池壁施工工艺，涉及污水处理技术领域，包括以下步骤S1、定位测量；S2、土方开挖；S3、基坑支护；S4、底层清理；S5、池壁浇筑：将池壁高度拆分成若干高度相同的浇筑区域，根据池壁厚度将浇筑区域沿纵向分为左浇筑区、中浇筑区和右浇筑区；S6、模板拆除；S7、表面处理；S8、基坑回填。通过先浇筑左浇筑区和右浇筑区使得预制模板分别与浇筑区和右浇筑区进行固定连接，然后进行中浇筑区内混凝土的浇筑，通过对池壁混凝土分区域进行浇筑使得超厚混凝土的凝固周期得到缩短，同时减少混凝土在浇筑时由于振捣不均匀导致混凝土凝固后空洞的概率，而分区进行浇筑也降低了超厚混凝土在铺设模板时的难度。
