Pile casing guiding device for deep-water shallow-coverage large-diameter pile casing cast-in-situ bored pile
The invention relates to the technical field of cast-in-situ bored pile construction, and particularly discloses a deep-water shallow-coverage large-diameter pile casing guide device for a cast-in-situ bored pile, which comprises a base ring, a plurality of adsorption parts are arranged on the lower side of the base ring, the lower side of each adsorption part adsorbs and fixes a lifting appliance, the lower sides of the lifting appliances are jointly and fixedly connected with a lifting ring, and the lower side of the lifting ring is coaxially and fixedly connected with an outer pile casing; the device further comprises a sinking ring, the sinking ring is located below the hanging ring, the sinking ring and the hanging ring are fixedly connected together through a pull rope, and at least one supporting rod is rotationally connected to an outer ring of the sinking ring. The guide device has the beneficial effects that the sinking ring sinks into a riverway to a riverbed under the action of gravity, at the moment, the bottoms of the three supporting rods and the bottoms of the reinforcing plates make close contact with the inclined face of the riverbed, and therefore the outer pile casing is supported; in addition, the pile casing does not deviate due to the fact that the upper surface of the riverbed is an inclined plane any more.
本发明涉及钻孔灌注桩施工技术领域，具体公开了一种深水浅覆盖大直径护筒钻孔灌注桩护筒导向装置，包括基环，基环下侧装有多个吸附件，每个吸附件下侧均吸附固定吊具，吊具下侧共同固定连接吊环，吊环下侧同轴固定连接外护筒；本发明还包括沉入环，沉入环位于吊环下方，且沉入环与吊环通过拉绳固定连接在一起，沉入环的外环上转动连接至少一个支撑杆。本发明的有益效果：发明所提供的一种深水浅覆盖大直径护筒钻孔灌注桩护筒导向装置把沉入环在重力作用下沉入河道直至河床上，此时三个支撑杆、加固板底部均与河床的倾斜面紧密接触，从而对外护筒进行支撑，如此外护筒不会再因为河床上表面为倾斜面而发生偏移。
