我们公司施工的污水处理厂生化水池项目,地处松花江沿岸,体量较大,长113.8m,宽59.8m,高7.2m,底板厚60cm,自然地面下埋深3.000m。水池底板和池壁不设施工缝,混凝土强度等级:底板C35,池壁C40。抗冻等级为F200,抗渗等级为P8。为保证生化水池的整体刚度和抗渗性,设计采用了超长预应力筋张拉施工技术。由于地下水位较高,施工难度较大,具体施工方法及技术要点如下。一、底板施工
The sewage treatment plant biochemical tank project constructed by our company is located on the coast of the Songhua River with a large volume of 113.8m long, 59.8m wide, 7.2m high and a bottom plate thickness of 60cm. The buried depth of natural ground is 3.000m. Pool floor and pool wall without facilities joints, concrete strength rating: floor C35, pool wall C40. Antifreeze grade F200, impermeability grade P8. In order to ensure the overall rigidity and impermeability of biochemical tanks, the design uses a long prestressed tendons tension construction technology. Due to the high groundwater level, the construction is difficult, the specific construction methods and technical points are as follows. First, the floor construction
