我厂生产的振动桩机由于简单实用,经济社会效益显著,近年来得到广泛应用。该桩机是由走管式桩架和DZ型振动锤配套而成,主要用来施工混凝土灌注桩、砂(或石灰、碎石)挤密桩等。桩管直径在200mm以上,对于较细的袋装砂井(俗称砂袋桩)从未施工过。1987年由于施工需要,我厂对沉桩部分作了改装设计,在温州机场工地取得良好效果。袋装砂井实际上就是堆载前设置的垂直排水通道,主要用以缩短排水时间,提高预
The vibratory pile driver produced by our factory is widely used in recent years due to its simplicity and practicality, and remarkable economic and social benefits. The pile driver is composed of pipe-type pile holder and DZ-type vibratory hammer. It is mainly used for the construction of concrete cast-in-place piles, sand (or lime, gravel) compaction piles and so on. The diameter of the pile pipe is more than 200mm, and it has never been constructed for the fine sand-packed sand wells (commonly known as sandbag piles). In 1987, due to construction requirements, our factory made a retrofit design for the pile-sinking section and achieved good results at the Wenzhou Airport site. Bag-packed sand well is actually a vertical drainage channel set before loading, mainly used to shorten the drainage time and improve pre-
