Construction method for eliminating side friction of pile foundation
The pile foundation side friction eliminating construction method comprises the following steps that firstly, after a reinforcement cage is machined, the outer side of an empty pile section of the reinforcement cage is wrapped with an inner protection wall, the inner protection wall is formed by overlapping galvanized iron sheets, the outer side of the inner protection wall is wrapped with an anti-seepage layer, the anti-seepage layer is formed by overlapping a plurality of polypropylene fiber coiled materials, and the outer side of the anti-seepage layer is wrapped with an anti-seepage layer; the outer side of the empty pile section of the reinforcement cage is wrapped with an outer protection wall, the outer protection wall is formed by overlapping galvanized iron sheets, then rubber water stop strips are installed between the top and the bottom of the inner protection wall and the top and the bottom of the outer protection wall, then the reinforcement cage is hoisted and put down, concrete is poured into the reinforcement cage, pile foundation maintenance is conducted, and finally pile foundation static load test detection is conducted; materials are simple, the cost is low, the pile foundation reinforcement cage horizontally lying on the flat ground is supported through the profiling supporting frame and the jack, the galvanized iron sheet and the polypropylene fiber coiled material can simply and rapidly wrap the outer side of the pile foundation reinforcement cage, the number of workers needed for wrapping the inner protection wall, the outer protection wall and the impermeable layer is reduced, and the construction efficiency is improved.
本发明公开一种桩基侧摩阻消除施工方法，包括以下步骤：首先，待钢筋笼加工完成后，在钢筋笼的空桩段外侧包裹内护壁，内护壁由镀锌铁皮搭接而成，其次在内护壁的外侧包裹防渗层，防渗层由若干丙纶卷材搭接而成，接着在钢筋笼的空桩段外侧包裹外护壁，外护壁由镀锌铁皮搭接而成，随后在内护壁和外护壁的顶、底之间安装橡胶止水条，然后起吊并下放钢筋笼，向钢筋笼内灌注混凝土，进行桩基养护，最后进行桩基静载试验检测；本发明的材料简单且成本也较低，通过仿形支撑架和千斤顶支撑横躺在平地上的桩基钢筋笼，使得镀锌铁皮和丙纶卷材能够简单快捷的包裹在桩基钢筋笼的外侧，减少了包裹内、外护壁和防渗层时所需的人员数量，加快了施工效率。
