Stiffened composite prefabricated enlarged toe pile and pile forming method thereof
The invention discloses a stiffened composite prefabricated enlarged toe pile and a pile forming method thereof. The stiffened composite prefabricated enlarged toe pile is composed of an inner enlarged toe concrete pile and peripheral equal-diameter stiffened solidified soil piles, wherein the inner enlarged toe concrete pile is a reinforced concrete precast pile, is in an inverted T shape and is composed of a pile end with an enlarged section and a pile body with a uniform section, and the peripheral equal-diameter stiffened solidified soil piles are pile bodies which are formed by changing foundation soil in pile holes into flow-state solidified soil through a mechanical drilling machine and solidifying the flow-state solidified soil. The pile forming method comprises the steps of changing the foundation soil in the pile holes into the flow-state solidified soil through the mechanical drilling machine, and implanting the inner pile into a pile position before the flow-state solidified soil is initially set. According to the stiffened composite prefabricated enlarged toe pile, various defects of a traditional cast-in-place enlarged toe pile are overcome, and the stiffened composite prefabricated enlarged toe pile is suitable for different stratums; and the method has green, environment-friendly, safe and reliable social benefits, can reduce the construction cost of the enlarged toe pile and shorten the construction period and has a great economic value.
本发明公开了一种劲性复合装配式扩底桩及其成桩方法，其劲性复合装配式扩底桩是由内芯的扩底混凝土桩和外围的等直径劲性固化土桩组成；内芯的扩底混凝土桩为钢筋混凝土预制桩，呈倒T形，是由扩大截面的桩端和等截面的桩身构成；外围的等直径的劲性固化土桩是由机械钻孔机具将桩孔内的地基土变成流态固化土固结成的桩体；其成桩方法是由机械钻孔机具将桩孔内的地基土变成流态固化土，在流态固化土初凝前将内芯桩植入到桩位中的方法。该专利解决了传统现浇扩底桩存在的各种缺陷，适用于不同的地层；并具有绿色、环保和安全可靠的社会效益，同时能降低扩底桩的造价和缩短工期，具有重大的经济价值。
