Cofferdam-free installation and construction method for bridge underwater straining beam
The invention relates to a cofferdam-free mounting construction method for a bridge underwater straining beam, and belongs to the field of hydraulic engineering. The cofferdam-free mounting construction method for the bridge underwater straining beam comprises the steps that S200, two bottom steel pipes are inserted into the water bottom; s300, the pile casings are hoisted and are in butt joint with the tops of the corresponding steel pipes; the pile casings are communicated with the corresponding steel pipes; ensuring that the first-order protective plates on the two protective cylinders are oppositely arranged; s400, a vertical reinforcement cage is inserted and extends into the steel pipe, and the bottom of the vertical reinforcement cage is inserted into the water bottom; s500, concrete is injected into all the steel pipes; s600, concrete in the pile casing is removed; the first-order protection plate is dismantled; s700, a cross beam is poured; s800, the cross beam is moved to the position between the two pile casings, and transverse reinforcement cages exposed out of the two ends of the cross beam are inserted into openings of the pile casings; it is ensured that the transverse reinforcement cage does not interfere with the vertical reinforcement cage; s900, a second-order protective plate is inserted into the opening of the protective cylinder, and the bottom of the second-order protective plate makes contact with the upper surface of the cross beam; s1000, concrete is poured into the pile casing; and S2000, after the concrete is solidified, the second-order protective plate and the protective cylinder are dismantled.
本发明涉及一种桥梁水中系梁无围堰安装施工方法，属于水利工程领域，桥梁水中系梁无围堰安装施工方法包括：S200、将两个底部钢管插入水底；S300、起吊护筒并将护筒对接对应的钢管顶部；使护筒与对应的钢管连通；确保两个护筒上的一阶护板相对设置；S400、将竖向钢筋笼插入并沿伸至钢管内部，底部插入水底；S500、向各钢管内注入混凝土；S600、去除护筒内的混凝土；拆除一阶护板；S700、浇筑横梁；S800、将横梁移动至两护筒之间，横梁两端漏出的横向钢筋笼插入护筒的开口内；确保横向钢筋笼不会与竖向钢筋笼产生干涉；S900、在护筒的开口处插入二阶护板，二阶护板的底部接触横梁的上表面；S1000、在护筒内浇筑混凝土；S2000、等待混凝土凝固后拆除二阶护板与护筒。
