Deep and thick easy-to-collapse stratum double-pile-casing wall protecting and hard rock rotary excavating hob base expanding construction equipment
The invention relates to the technical field of pile hole bottom expanding, and discloses double-pile-casing wall protection and hard rock rotary excavating hob bottom expanding construction equipment for a deep and thick easy-to-collapse stratum. Comprising a vibratory hammer, an outer pile casing, an inner pile casing, a rotary drilling rig, a cone barrel drill and a reamer bit, wherein the outer pile casing and the inner pile casing are tripped into a soil layer by utilizing the vibratory hammer, the rotary drilling rig is used for drilling a soil body from the soil layer in the inner pile casing to form a soil layer hole, the cone barrel drill is used for drilling and coring in a rock stratum to form a rock stratum hole, and a plurality of rotary drilling hobs expanding outwards or folding inwards are arranged on the periphery of the reamer bit. The rotary excavating hob is used for expanding and cutting the inner side wall of the rock stratum hole in the rock stratum hole, so that the rock stratum hole forms an expanded hole; the inner pile casing is arranged in the outer pile casing; the bottom of the inner pile casing abuts against the rock stratum, and the soil layer hole and the expansion hole are communicated up and down to form a pile hole. The hole cleaning structure is arranged outside the pile hole, then a reinforcement cage is put into the pile hole, concrete is poured, a cast-in-place pile can be formed, and the effects of being reliable in quality, rapid in drilling and expanding, safe, convenient to use and economical in cost are achieved.
本发明涉及桩孔扩底的技术领域，公开了深厚易塌地层双护筒护壁与硬岩旋挖滚刀扩底施工设备，包括振动锤、利用振动锤下入在土层中的外护筒以及内护筒、对内护筒中的土层钻取土体以形成土层孔的旋挖钻机、在岩层中钻进取芯以形成岩层孔的牙轮筒钻以及扩孔钻头，扩孔钻头的外周设有多个朝外扩张或朝内收拢的旋挖滚刀，旋挖滚刀在岩层孔中对岩层孔的内侧壁进行扩张切屑以使岩层孔形成扩张孔；内护筒布设在外护筒中；内护筒的底部抵接在岩层上，土层孔与扩张孔上下连通，形成桩孔；桩孔的外部设有清孔结构，而后再通过在桩孔中下入钢筋笼以及灌注混凝土，即可形成灌注桩，达到了质量可靠、钻扩快捷、安全便利、成本经济的效果。
