Stiff composite expanded head anchoring body and construction method thereof
The invention provides a stiff composite expanded-head anchoring body and a construction method thereof. The stiff composite expanded-head anchoring body comprises an expanded-head anchor rod part, a cement-soil mixing pile part and an accessory part. The expanded head anchor rod part comprises an expanded section and a non-expanded section, the expanded section is composed of a main reinforcement, a retractable reinforcement cage and an expanded section grouting body, and the non-expanded section is composed of a main reinforcement and a non-expanded section grouting body. The cement-soil mixing pile part is formed by mixing a soil body and cement and located on the upper portion of the stiff composite expanded head anchoring body. The non-expanded section of the expanded head anchor rod part penetrates through the axis of the cement mixing pile part, the expanded section is located below the cement mixing pile part, and the top end of the expanded section is embedded into the bottom end of the cement mixing pile part. The accessory part comprises an anchor head bolt, an anchor head base plate, a reinforcement cage upper bolt, a reinforcement cage lower bolt and a reinforcement cage loading plate. By means of the method, the construction speed is increased, the economic cost is reduced, and certain reference value is achieved for research of the power transmission line infrastructure rock-soil body reinforcement technology.
本发明提供一种劲性复合扩大头锚固体及其施工方法，包括扩大头锚杆部分、水泥土搅拌桩部分和配件部分。扩大头锚杆部分包括扩大段和未扩大段，其中扩大段由主筋、可收缩钢筋笼和扩大段注浆体构成，未扩大段由主筋和未扩大段注浆体构成。水泥土搅拌桩部分由土体与水泥搅拌而成，位于劲性复合扩大头锚固体的上部。扩大头锚杆部分的未扩大段贯穿于水泥土搅拌桩部分轴线，扩大段位于水泥土搅拌桩部分下方，扩大段顶端嵌入水泥土搅拌桩部分底端。配件部分包括锚头螺栓、锚头垫板、钢筋笼上部螺栓、钢筋笼下部螺栓和钢筋笼载荷板。通过本发明，施工速度加快，经济成本降低，对输电线路基础建设岩土体加固技术研究具有一定参考价值。
