Precast pile stress release hole for soft soil foundation and construction method
The invention discloses a precast pile stress release hole for a soft soil foundation and a construction method, and the method comprises the following steps: S100, drawing a plane layout diagram of the stress release hole according to the field condition, and carrying out hole site lofting on the plane layout diagram; s200, a site hole site is determined according to the plane layout diagram, after a drilling machine is in place, hole guiding is conducted through the drilling machine, construction is conducted in cooperation with a punching and pulling machine, and a pile casing is buried into the site hole site; s300, a drilling machine is used for conducting rotary excavating and drilling operation in the sequence from slow to fast till the drilled hole reaches the preset depth, and hole completion of the soil hole is achieved; s400, the structure of the stress release unit is optimized according to the hole completion size of the soil hole, and the specific size suitable for the field actual engineering geology is determined; s500, the punching and pulling machine is used for being aligned with the center of the soil hole to hoist the stress releasing unit into the soil hole, and the stress releasing unit is controlled not to float upwards; and S600, the steel casing is slowly pulled out through vibration of a beating and pulling machine, and a cover plate is manufactured through a formwork batten to protect the hole opening of the stress release hole. And the problem of soil squeezing effect of the soft soil foundation is solved.
本发明公开了一种用于软土地基的预制桩应力释放孔及施工方法，方法包括：S100、根据现场情况绘制应力释放孔的平面布置图，并对该平面布置图进行孔位放样；S200、根据平面布置图确定现场孔位，钻机就位后由钻机进行引孔，配合打拔机施工，埋设护筒至现场孔位中；S300、使用钻机按照先慢后快的顺序进行旋挖钻孔作业，直至钻孔达到预设深度，实现土孔的完孔；S400、根据土孔的完孔尺寸优化应力释放单元的结构，确定适用现场实际工程地质的具体尺寸；S500、利用打拔机对准土孔中心将应力释放单元吊装入土孔中，控制应力释放单元不上浮；S600、使用打拔机震动缓慢拔出钢护筒，采用模板木方制作盖板对应力释放孔洞口进行防护。解决了软土地基挤土效应的问题。
