Open caisson blade foot structure, open caisson sinking intelligent control system and construction method
The invention discloses an open caisson blade foot structure, an open caisson sinking intelligent control system and a corresponding construction method. The open caisson blade foot structure comprises a blade foot sector ring section with a mud sleeve and a blade foot sector ring section without a mud sleeve, and the blade foot sector ring section with the mud sleeve and the blade foot sector ring section without the mud sleeve are alternately welded in the circumferential direction to form the open caisson blade foot structure. The radial outer ring section of the non-mud sleeve blade foot sector ring section is flush with the outer surface of the well wall of the open caisson; the radial outer ring section with the mud sleeve blade foot sector ring section is a mud collecting groove with an upward opening, and the radial outer wall of the mud collecting groove protrudes out of the outer surface of the well wall of the open caisson. The well wall corresponding to the blade foot sector ring section without the mud sleeve plays a role in positioning, guiding and deviation prevention of the open caisson, deviation correction of the open caisson is carried out by applying different pressures to different parts of the mud sleeve, grouting does not impact a sandy gravel stratum, rapid forming of a mud lubricating layer is facilitated, and the situation that a large amount of mud enters the sandy gravel stratum and pollutes underground water is also prevented.
本发明公开了一种沉井刃脚结构、沉井下沉智能控制系统及相应的施工方法。沉井刃脚结构包括有泥套刃脚扇环段和无泥套刃脚扇环段，有泥套刃脚扇环段和无泥套刃脚扇环段在周向方向上交替焊接形成沉井刃脚结构；无泥套刃脚扇环段的径向外环段与沉井的井壁外表面相平齐；有泥套刃脚扇环段的径向外环段为开口向上的集泥槽，集泥槽的径向外壁凸出沉井的井壁外表面。无泥套刃脚扇环段对应的井壁对沉井起到定位、导向和防偏的作用，通过对泥浆套不同部位施加不同压力来进行沉井纠偏，注浆不冲击砂卵石地层，既有利于泥浆润滑层快速形成，也防止泥浆大量进入砂卵石地层而污染地下水。
