Pile foundation dismantling underwater platform and construction method
The invention relates to a pile foundation dismantling underwater platform and a construction method, the pile foundation dismantling underwater platform comprises barges, a crane ship and a steel platform frame, the multifunctional steel platform frame is erected between the two barges, and the multifunctional steel platform frame is provided with a platform top surface steel plate with an operation hole easy to open and close and a material moving and placing device; the construction method for dismantling the underwater platform through the pile foundation comprises the steps that construction preparation is conducted; setting out a pile position; constructing a construction platform; a pile foundation is in place, and a pile casing is embedded; high-pressure water and compressed air are used for punching and friction reduction; removing the old pile; and pile hole backfilling. The method has the beneficial effects that high-pressure water and compressed air are adopted for punching and friction reduction, the construction process is relatively simple, the construction efficiency is high, time can be gained for subsequent procedures, and the construction progress is guaranteed; the platform top material moving and placing device is adopted, and the problem that in the prior art, material conveying equipment lacks a fixing device is solved; and by adopting the easy-to-pull-out mud surface stabilizing device for the steel casing, the stability of the soil body after the steel casing is pulled out is ensured.
本发明涉及一种桩基拆除水中平台及施工方法，这种桩基拆除水中平台包括驳船、起重船和钢平台架，多功能钢平台架设在两艘驳船之间，多功能钢平台架上设有带易启闭操作孔的平台顶面钢板和物料移放装置；这种桩基拆除水中平台的施工方法包括步骤：施工准备；桩位放样；施工平台建设；桩基就位，埋设护筒；高压水及压缩空气冲孔减摩；旧桩拆除；桩孔回填。本发明的有益效果是：采用高压水及压缩空气冲孔减摩，施工工艺相对简单，施工效率高，可以为后续工序赢得时间，保证了施工进度；采用平台顶部物料移放装置，解决了现有技术中的物料运送设备缺乏固定装置的问题；采用钢护筒易拔除泥面稳固装置，确保钢护筒拔除后土体稳定。
