Bottom-supported self-elevating platform and pile inserting method
The invention discloses a bottom-supported self-elevating platform and a pile inserting method. The pile inserting method of the bottom-supported self-elevating platform comprises the following steps:S10, the platform is shifted to a specified position; S20, pile legs are pre-stretched; S30, a lower floating body is descended to a seabed; S40, an upper ship body is lifted away from the water surface; S50, the lower floating body is pre-loaded to a target load; S60, the pile legs are pre-loaded to a target load; and S70, the upper ship body is lifted to a working air gap. According to the pileinserting method of the bottom-supported self-elevating platform, a large amount of ballast water does not need to be injected, the problem of poor platform stability caused by surge attack is solved, and the pile inserting method is suitable for the softer ground; and in addition, the platform is more stable through the mode that the lower floating body and the pile legs bear together and the load is adjustable.
本发明公开了一种坐底自升式平台及插桩方法，其中坐底自升式平台插桩方法包括：步骤S10：平台移位至指定位置；步骤S20：预伸桩腿；步骤S30：下放下浮体至海床；步骤S40：抬升上船体离开水面；步骤S50：预压载下浮体至目标载荷；步骤S60：预压载桩腿至目标载荷；步骤S70：抬升上船体至工作气隙。本发明的坐底自升式平台插桩方法，无需大量注入压载水，同时既解决了因涌浪侵袭而导致平台稳定性较差的问题，又适用于较软质地；另外通过下浮体与桩腿共同承担且载荷可调的模式使平台更稳定。
