我公司承建的某市污水处理厂氧化沟工程,长120m,宽55m,总面积达6600m~2。厚40cm 的底板由橡胶止水带分割成17块,最小块的面积为250m~2,最大块的面积为500m~2。由于每块底面积大,工程质量要求高,且采用泵送混凝土,因此,混凝土浇筑采取如下方法,取得了很好的效果。1.如图1所示,底板钢筋绑扎完成后(钢筋保护层厚度为35mm),取直径12mm 钢筋头(l=390mm)垂直于底板点焊在底板直径16mm 钢筋上,沿横向间距每米1根布置,且成一条直
The oxidation ditch project of a city sewage treatment plant contracted by our company is 120m long and 55m wide with a total area of 6600m ~ 2. The 40cm thick bottom plate is divided into 17 blocks by a rubber water stop, with the minimum block area of 250m ~ 2 and the largest block area of 500m ~ 2. As each floor area is large, high quality engineering requirements, and the use of pumping concrete, concrete pouring to take the following method, and achieved good results. 1. As shown in Figure 1, after rebar reinforcement banding is completed (rebar thickness is 35mm), take a diameter of 12mm steel head (l = 390mm) perpendicular to the floor spot welding on the floor diameter of 16mm rebar, along the lateral spacing of 1 per meter Root layout, and into a straight
