Equipment for karst geology pile foundation drilling and grouting method for construction thereof
The invention belongs to the field of pile foundation percussion drills, and particularly relates to equipment for karst geology pile foundation drilling and a grouting method for the construction thereof. The equipment comprises a percussion drill mechanism, a swing limiting mechanism, and a grouting auxiliary mechanism; the percussion drill mechanism is hung on a steel wire rope A of a percussion drilling machine; and the percussion drill mechanism conducts reciprocating percussion crushing on a rock stratum under the reciprocating traction of the steel wire rope A, and then a percussion drill hole is formed in the rock stratum. According to the equipment for karst geology pile foundation drilling and the grouting method for the construction thereof, through effective cooperation of the swing limiting mechanism and the percussion drill mechanism, effective percussion drilling operation is carried out on the geology of a plurality of vertically and continuously distributed karst caves, and the swing limiting mechanism carries out proper swing limitation on the percussion drill mechanism according to the steep degree of slopes at the bottoms of the karst caves.
本发明属于桩基冲击钻领域，尤其涉及一种用于岩溶地质桩基钻孔的设备及其施工的灌浆方法，它包括冲击钻机构、限摆机构、灌浆辅助机构，其中冲击钻机构吊挂在冲击钻探机的钢丝绳A上，冲击钻机构在钢丝绳A的往复牵引下对岩层进行往复冲击破碎，进而在岩层上形成冲击钻孔；本发明通过限摆机构与冲击钻机构的有效配合对竖直连续分布若干溶洞的地质进行有效的冲击钻孔作业，限摆机构根据所遇溶洞底部斜坡的陡峭程度对冲击钻机构进行适当的摆动限制。
