Composite stiff pile head connecting method for pile foundation engineering
The invention discloses a composite stiff pile head connecting method for pile foundation engineering, which comprises the following steps of: firstly, manufacturing a prestressed high-strength pipe pile, namely mounting a double-T-shaped grouting sleeve, mounting a mold, pouring concrete, performing prestressed tensioning, forming, performing autoclaved curing and the like. Secondly, static pile pressing of the outer core cement pile is conducted on site through a high-pressure equal-diameter deep stirring technology; then, a reinforcing steel bar supporting plate is installed in the tubular pile cavity, and the upper structural reinforcing steel bar is connected with the tubular pile head connecting reinforcing steel bar through the double-T-shaped grouting sleeve. And then, high-strength grouting materials are injected into the double-T-shaped grouting sleeves through the grouting openings, so that the upper structure steel bar connecting signs and the pipe pile head connecting steel bars are tightly connected in the high-strength grouting materials. And finally, strength detection is conducted on the pile head node, and after the strength meets the requirement, the next procedure is conducted.
本发明公开了一种用于桩基工程的复合劲性桩桩头连接方法，包括以下步骤：首先，制作预应力高强管桩，其中包括安装双“T”型灌浆套筒、模具安装、灌注混凝土、预应力张拉、成型和蒸压养护等。其次，在现场使用高压等径深层搅拌工艺进行外芯水泥桩的静力压桩。然后，在管桩空腔内安装钢筋托板，并通过双“T”型灌浆套筒将上部结构钢筋与管桩桩头连接钢筋相连。随后，使用高强灌浆料通过灌浆口注入双“T”型灌浆套筒，使上部结构钢筋连接示意和管桩桩头连接钢筋在高强灌浆料内紧密相连。最后，对桩头节点进行强度检测，当强度达到要求后，进行下一道工序。
