Construction method of temporary steel bridge underwater steel pipe pile foundation for hard rock riverbed
The invention discloses a construction method for an underwater steel pipe pile foundation of a temporary steel bridge for a hard rock riverbed. The construction method comprises the steps that the position of a steel pipe pile is positioned, and drilling is conducted; processing a steel casing; a steel pipe pile reinforcement cage framework is manufactured, and after the steel pipe pile reinforcement cage framework partially penetrates into the steel pipe pile, the steel pipe pile reinforcement cage framework and the steel pipe pile are fixed; the end, provided with the steel pipe pile reinforcement cage framework, of the steel pipe pile penetrates into the end, not provided with the iron wire net ring, of the steel casing, and then the steel casing and the steel pipe pile are fixed; cleaning a riverbed near the drill hole and the pile position; slowly lowering the steel pipe pile to enable the steel pipe pile reinforcement cage framework to accurately enter the drilled hole; after the perpendicularity of the steel pipe pile is adjusted, concrete is poured into the steel pipe pile through an opening in the upper end of the steel pipe pile. According to the construction method of the temporary steel bridge underwater steel pipe pile foundation for the hard rock riverbed, the construction steps are simple, related materials are easy to obtain on site, the cost is low, construction can be completed conveniently and rapidly, and the application prospect is good.
本发明公开了一种硬岩河床用的钢便桥水下钢管桩基础施工方法，步骤：定位钢管桩位置并钻孔；加工钢护筒；制作钢管桩用钢筋笼骨架，并将钢管桩用钢筋笼骨架部分穿入钢管桩中后将钢管桩用钢筋笼骨架与钢管桩固定；将钢管桩安有钢管桩用钢筋笼骨架端从钢护筒未安铁丝网圈端穿入，再将钢护筒与钢管桩固定；清理钻孔及桩位附近河床；缓缓下放钢管桩使得钢管桩用钢筋笼骨架准确进入所钻孔内；调整钢管桩垂直度后通过钢管桩上端开口向钢管桩内灌注混凝土。本发明的硬岩河床用的钢便桥水下钢管桩基础施工方法，施工步序简单，所涉及到的材料均为现场易得的，成本低廉，可以方便快捷地完成施工，应用前景好。
