Method for manufacturing pile foundation for additionally installing elevator
The invention provides a method for manufacturing a pile foundation for additionally installing an elevator, which comprises the following steps of: manufacturing a base plate, pre-embedding a claw type anchor rod, and reserving a pile pressing hole of which the cross section is in the shape of a wedge with a narrow upper part and a wide lower part; erecting static pile pressing equipment on the base plate, and pressing the precast pile into the foundation by the static pile pressing equipment; after the precast pile is pressed in, static pressure pile equipment is dismantled, anchoring steel bars are welded to the pile end, cross connecting steel bars are welded to the claw type anchor rod in a cross mode, and the anchoring steel bars, the cross connecting steel bars and the claw type anchor rod are welded into a whole; formwork erecting is conducted on the periphery of the claw type anchor rod, concrete is poured to cover the pile pressing hole, the prefabricated pile, the claw type anchor rod, the anchoring steel bars and the cross connecting steel bars, and the concrete and the base plate form a whole; according to the method, drilling is not needed firstly, counter force is provided for static pressure pile equipment through the dead weight of the base plate, the precast pile is locked through extrusion of the wedge-shaped pile pressing opening, the precast pile and the base plate are combined more tightly and firmly, construction is noiseless, muddy water cannot be discharged, pollution is avoided, and the construction efficiency is improved.
本发明提供一种用于加装电梯的桩基制作方法，包括如下步骤：制作基板，预埋爪式锚杆，并预留压桩洞口，压桩洞口的横截面形状为上窄下宽的楔形；在基板上架设静压桩设备，静压桩设备将预制桩静压入地基；预制桩压入后拆除静压桩设备，在桩端焊接锚固钢筋，在爪式锚杆上交叉焊接有交叉连接钢筋，并将锚固钢筋、交叉连接钢筋以及爪式锚杆焊接形成整体；在爪式锚杆四周支模，灌注混凝土覆盖压桩洞口、预制桩、爪式锚杆、锚固钢筋和交叉连接钢筋，并与基板形成整体；本发明无需先钻孔，利用基板的自重给静压桩设备提供反力，且楔形的压桩洞口挤压将预制桩锁紧，使预制桩与基板的结合更为紧密牢靠，施工无噪声，不会排出泥水无污染，施工效率提高。
