Construction method of water trestle ground screw miniature steel pipe pile
The invention discloses a construction method of a water trestle road ground screw miniature steel pipe pile. The construction method comprises the steps that a water operation platform is built; the overwater operation platform comprises a floating base and a screwing machine fixing door frame. Positioning and paying off are conducted in the construction area of the water trestle to be constructed, and the target pile position and the ground screw elevation are determined; the ground screw miniature steel pipe pile is vertically arranged at a target pile position, a screwing machine is connected with the pile top of the ground screw miniature steel pipe pile, and the screwing machine is fixed to a screwing machine fixing portal; a screwing machine is controlled to rotationally lower the ground screw miniature steel pipe pile to the ground screw elevation position; and under-pressure grouting construction of pile body cement mortar is carried out on the ground screw miniature steel pipe pile. The technical problem that large and medium-sized machines cannot enter a site to carry out large-area construction in overwater operation construction is solved.
本发明公开了一种水上栈道地螺丝微型钢管桩施工工法，包括：搭建水上操作平台；水上操作平台包括：漂浮底座和旋紧机固定门架；在待施工水上栈道的施工区域进行定位放线，并确定目标桩位和地螺丝标高；将地螺丝微型钢管桩垂直立于目标桩位处，将旋紧机与地螺丝微型钢管桩的桩顶连接，并将旋紧机固定于旋紧机固定门架上；控制旋紧机对地螺丝微型钢管桩进行旋转下桩至地螺丝标高位置；对地螺丝微型钢管桩进行桩身水泥砂浆的带压注浆施工。本发明缓解了水上作业施工中大中型机械无法进入现场开展大面积施工的技术问题。
