预制桩是在工厂或工地加工制作的钢筋混凝土成品桩。一般较短的桩多在预制厂生产,而较长的桩则在打桩现场或附近就地预制。预制桩可分为桩尖、桩身和桩顶三段。预制桩具有制作方便、成桩速度快、桩身质量易于控制、承载力高等优点,且不受地下水位影响,不存在泥浆排放问题,是最常用的一种桩型。沉桩的施工方法有锤击沉桩法、静力压桩法、振动法、旋入法和水冲沉桩法。本文现就预制桩的制作、起吊、运输和堆放技术办法做浅要探讨和谈论。 Prefabricated piles are manufactured in the factory or site of the finished steel reinforced concrete piles. Generally shorter piles are often produced at prefabricated plants while longer piles are prefabricated on-site at or near the piling site. Precast piles can be divided into pile tip, pile and pile top three sections. Precast piles have the advantages of easy manufacture, fast pile forming speed, easy control of pile mass, high bearing capacity, etc., and are not affected by groundwater level. There is no problem of mud discharge, which is the most commonly used pile type. Sinking construction methods hammer hammer sinking method, static pressure pile method, vibration method, screwing method and sinking pile method. This article is on precast piles production, lifting, transport and stacking techniques to do a brief discussion and discussion.
