Large-diameter while-drilling pipe-following drainage pile device and construction method thereof
The invention discloses a device of a large-diameter while-drilling pipe-following drainage pile and a construction method of the large-diameter while-drilling pipe-following drainage pile, a concrete drainage plate is fixed on a pile body of a prefabricated pipe pile while the prefabricated pipe pile drills along with a spiral drill bit, and the pipe pile with the prefabricated concrete drainage plate can be brought into a foundation together. According to the while-drilling pipe-following drainage pile, slurry pollution caused by drilling grouting is avoided, meanwhile, the concrete drainage plate can quickly reduce the water content of cement around the pile, the curing time of the cement around the pile is shortened, the bearing capacity and stability of the prefabricated pipe pile are guaranteed, the concrete drainage plate can help drainage consolidation of soil around the pile, and the construction efficiency is improved. The concrete drainage plate is fixed to the pipe pile body while drilling, drainage consolidation of the soil body around the pile can be accelerated, the bearing capacity and long-term use of the pile foundation can be guaranteed, and the construction method is simple and convenient to implement and high in practicability. The strength of the soil body around the pile is improved, so that the bearing capacity and the deformation resistance of the pile foundation are enhanced, and the concrete drainage plate is convenient to replace and can guarantee long-term use of the pipe pile. And the method is suitable for construction in various complex environments.
本发明公开了一种大直径随钻跟管排水桩的装置及其施工方法，预制管桩随着螺旋钻头钻进的同时，在预制管桩桩身固定混凝土排水板，可以将有预制混凝土排水板的管桩一同带入地基，随钻跟管排水桩在避免钻孔注浆导致泥浆污染的同时，混凝土排水板可以起到快速减少桩周水泥的含水率，减少桩周水泥的固化时间，保证预制管桩的承载能力和稳定性，且混凝土排水板可以帮助桩周土体的排水固结，提高桩周土体的强度，从而强化桩基的承载力和抗变形能力，混凝土排水板自身方便替换，可以保证管桩的长久使用，本发明采用在随钻跟管桩身固定混凝土排水板，可以加快桩周土体的排水固结保证桩基的承载能力和长久使用，适用于多种复杂环境的施工。
