Seabed automatic drilling type piling device and method
The invention discloses a seabed automatic drilling type piling device and method. The seabed automatic drilling type piling device comprises an expansion fixing module, an upper anchoring module, a lower anchoring module, a chip removal module and a drilling module, and a mooring rope can be dragged to automatically drill into a seabed rock stratum to achieve anchoring; the drilling module can drill the seabed rock stratum; the chip removal module can automatically transfer rock chips to the rear of the device, so that efficient chip removal and drilling are realized; the upper anchoring module and the lower anchoring module play a role of fixing the device during drilling, and can assist in anchoring after drilling to a specified anchoring depth; when an extrusion head is subjected to upward pulling force applied by the mooring rope, an expansion cover in the expansion fixing module deforms and opens under the action of the extrusion head, the friction force between the expansion cover and the rock chips is increased, and therefore reliable anchoring is achieved. The problems of insufficient seabed shallow non-diagenetic piling depth and unreliable anchoring are mainly solved, high automation and controllable piling depth are realized, and the seabed automatic drilling type piling device and method are suitable for piling operation requirements of different water depths and various seabed lithology.
本发明公开了一种海底自动钻进式打桩装置及方法，它由膨胀固定模块、上部锚定模块、下部锚定模块、排屑模块和钻进模块组成，可以拖动缆绳自动钻进到海底岩层中实现锚定；钻进模块可以钻开海底岩层，排屑模块可将岩屑自动运移到装置后方，实现高效排屑与钻进；上部锚定模块和下部锚定模块在钻进时起到固定装置作用，在钻到指定的锚定深度后，可以辅助锚定；挤压头受到缆绳施加的向上拉力时，膨胀固定模块中的膨胀盖在挤压头作用下会变形张开，增大膨胀盖与岩屑的摩擦力，从而实现可靠锚定。本发明主要解决了海底浅层非成岩打桩深度不够，锚定不可靠的问题，实现了高度自动化，且打桩深度可控，适用于不同水深和多类海底岩性打桩作业需求。
