Grouting bamboo joint pile foundation and construction method thereof
The invention discloses a grouting bamboo joint pile foundation which comprises a bamboo joint pile sinking underground, the bamboo joint pile comprises a pile body and bamboo joint protrusions arranged on the pile body, at least one pipe inserting hole set is formed in the bamboo joint pile, and each pipe inserting hole set comprises a pipe inserting hole formed in the corresponding bamboo joint protrusion. A wrapping shell formed by cement paste is arranged between the bamboo joint pile and the underground soil body, the cement paste is injected through a grouting pipe inserted into the pipe inserting hole, and after the cement paste is injected, the grouting pipe is pulled out and recycled. The invention further discloses a construction method of the grouting bamboo joint pile foundation. The pipe inserting holes are formed in the bamboo joint protrusions, so that the grouting pipe can gradually inject cement paste into the gap between the bamboo joint pile and the underground soil body from bottom to top, by means of the segmentation effect of the bamboo joint protrusions, a leaking stoppage air bag is avoided, the grouting pressure of a local area can be increased, the density of cement soil in the corresponding area is increased, and the grouting efficiency is improved. And the distance of the cement paste permeating into the surrounding soil body is adjusted so as to guarantee the pile side friction resistance.
本申请公开了一种注浆竹节桩基础，其包括下沉在地下的竹节桩，竹节桩包括桩身和设置在桩身上的竹节凸起，在竹节桩上设置有至少一个插管孔组，每个插管孔组均包括设置在每一竹节凸起上的一个插管孔，在竹节桩与地下土体之间具有由水泥浆所形成的包覆壳，水泥浆由插入到插管孔内的注浆管注入，在完成水泥浆的注入后，注浆管被拔出回收。本申请还公开了注浆竹节桩基础的施工方法。本申请在竹节凸起上设置插管孔，使得注浆管能够由下向上逐渐向竹节桩与地下土体之间的缝隙内注入水泥浆，利用竹节凸起的分割作用，避免采用堵漏气囊，还能对局部区域提高注浆压力，以提高相应区域内水泥土的密度，以及水泥浆渗入到周围土体的距离，以保证桩侧摩阻力。
