Definitions

  • the present application relates to a squeezing and expanding perfusion technique, and more particularly to a reinforced and expanded pile bearing plate reinforcement device.
  • the squeezed and expanded pile is a new type of variable section pile type in recent years, which has the characteristics of multi-layer distributed bearing. It is based on the borehole of the bored pile, using special equipment to squeeze into the upper and lower symmetrical cavity in the pile body, and then the pile body, the bearing plate and the pile root jointly formed by pouring the concrete, As shown in Figure 1. Because the bearing plate increases the effective bearing area of the pile body, it has a compacting effect on the surrounding soil during the expansion and expansion.

It is beneficial to greatly shorten the length of the pile, reduce the amount of concrete, and save the construction period, which has a very broad application prospect.

技术领域
本申请涉及挤扩灌注技术,尤其涉及一种挤扩灌注桩承力盘配筋装置。
背景技术
挤扩灌注桩是近年来新兴的一种变截面桩型,具有多层分散承载的特点。它是在钻孔灌注桩钻孔的基础上,使用专用的设备在桩身挤扩成上下对称的空腔,然后浇灌混凝土后形成的桩身、承力盘和桩根共同承载的桩型,如图1所示。由于承力盘增大了桩身的有效承载面积,挤扩时对周围土体有挤密作用,与普通直孔灌注桩相比,挤扩灌注桩充分利用了土层的地基承载力,单桩承载力比普通直孔灌注桩有较大提高,并具备良好的抗拔承载性能。有利于大大缩短桩长、降低混凝土用量、节约工期,具有非常广阔的应用前景。
研究表明,挤扩灌注桩在承载时,承力盘承受了大部分桩基荷载,此时,承力盘主要承受压剪应力,在现实中,由于承力盘位于桩身位置,无法为承力盘进行常规的抗剪配筋,承力盘容易损坏。
