Cast-in-place pile grouting device and method
The invention relates to the technical field of grouting of cast-in-place piles, and provides a grouting device and method for cast-in-place piles. The grouting mechanism comprises a grouting hose, a vibrating device and a guide steel pipe; the guide steel pipe is positioned in the reinforcement cage; the vibrating device is in sliding fit with the guide steel pipe; the grouting mechanism comprises a grouting device, a grouting steel pipe, a pile end grouting head, a plurality of pile side temporary closing assemblies and a grouting lifting mechanism. The grouting steel pipe is nested in the guide steel pipe, and the top of the grouting steel pipe is connected with a grouting device; a plurality of side grouting holes are formed in the side wall of the guide steel pipe in the vertical direction at intervals; slurry discharging holes are formed in the side wall of the grouting steel pipe; and pile side temporary sealing assemblies are arranged on the inner wall of the grouting steel pipe, and the grouting lifting mechanism is used for lifting the multiple pile side temporary sealing assemblies one by one so as to open the grout discharging holes one by one. The vibrating effect is better, grout is discharged from the grout discharging holes layer by layer to reinforce soil on the side of the pile, grouting is uniform, the grouting pressure is large, and the bearing capacity of a single pile is improved.
本申请涉及灌注桩注浆技术领域，提供了一种灌注桩注浆装置和方法，包括：灌浆机构和注浆机构；灌浆机构包括：灌浆软管、振捣装置和导向钢管；导向钢管位于钢筋笼内；振捣装置与导向钢管滑动配合；注浆机构包括：注浆装置、注浆钢管、桩端注浆头、多个桩侧临时封闭组件、注浆提升机构；注浆钢管嵌套于导向钢管内部，注浆钢管的顶部连接注浆装置；导向钢管的侧壁沿竖向间隔设置有多个侧注浆孔；注浆钢管的侧壁设置有排浆孔；注浆钢管的内壁设置有桩侧临时封闭组件，注浆提升机构用于逐一提升多个桩侧临时封闭组件以逐一的开启排浆孔。本发明的振捣效果更好，浆液逐层的从排浆孔排出加固桩侧土体，注浆均匀，注浆压力大，提高了单桩承载力。
