Construction method of super-large-area concrete anti-cracking and anti-floating structure
The invention discloses a construction method of an ultra-large-area concrete anti-cracking and anti-floating structure, which comprises the following steps: step 1, preparation before construction: dividing a large surface of a construction site into warehouses, and entering the construction site after materials required for construction are accepted and accepted to be qualified; secondly, reinforcing steel bars for concrete pouring are bound, the water stop steel plates are welded, and the water stop steel plates are welded through the double-face full-length welding technology; thirdly, concrete pouring is conducted, construction is conducted through a warehouse jumping method, and pre-control measures are taken in advance on the easily-cracked portions of concrete; fourthly, the temperature post-cast strip and the joint of all the blocks are continuously constructed through the temperature post-cast strip, and local strengthening treatment is conducted on the post-cast strip, the deformation joint and the induction joint; fifthly, rotary excavating and hole forming are carried out, cast-in-situ bored pile construction is carried out on the cast-in-situ bored concrete integration, and a cast-in-situ pile is anchored into a foundation bottom plate; step 6, protecting and accepting finished products; the iron gauze or the small-diameter reinforcing mesh is additionally arranged on the foundation surface rib, so that the crack resistance of the concrete is improved.
本发明公开了一种超大面积混凝土防裂抗浮构造施工方法，包括以下步骤：步骤一、施工前准备，对施工现场大面进行分仓，将施工所需材料验收合格后进场；步骤二、绑扎混凝土浇筑用钢筋，并且对止水钢板进行焊接，止水钢板采用双面满焊的焊接工艺；步骤三、混凝土浇筑，采用跳仓法施工，并对混凝土易开裂部位提前进行预控措施；步骤四、温度后浇带，各区块交接处采用温度后浇带行连续施工，对后浇带、变形缝、诱导缝进行局部加强处理；步骤五、旋挖成孔，在浇筑后的混凝土集成进行钻孔灌注桩施工，将灌注桩锚入基础底板；步骤六、成品保护及验收；本发明在基础面筋上增设铁丝网或小直径钢筋网，以提高混凝土抗裂性。
