Carrier pile machine compaction karst cave filler and karst cave filling method
The invention discloses a carrier pile machine compaction karst cave filler and a karst cave filling method, and relates to the technical field of karst cave filling. According to the karst cave filler, soil mixed stone prepared by mixing stone flakes and broken stone, gravels, backfill clay, cement and fly ash according to a ratio of 1:1:3:0.2:0.2 is used as a filler, drilling is performed by a rotary drilling machine, karst cave is filled to the ground layer by layer through a carrier pile machine, stone flakes are used as bottom, soil mixed stone prepared by mixing broken stone, gravel, backfill clay, cement and fly ash is used for gap filling, and compaction is performed layer by layer. According to the invention, the adopted raw materials are simple and easy to obtain, the used engineering instruments are convenient and conventional, the requirement and specification of karst cave filling can be met after layer-by-layer compaction, the pile forming quality of a karst cave area isensured, the filling efficiency and the pile forming quality are high, and the method is suitable for application and popularization.
本发明公开一种载体桩机夯实溶洞填充物及溶洞填充方法，涉及溶洞填充技术领域。本发明的溶洞填充物以片石及碎石、砂石、回填粘土、水泥和粉煤灰按1:1:3:0.2:0.2混合的土夹石作为填充物，由旋挖机打孔并由载体桩机逐层的将溶洞进行填充至地面，以片石为底，碎石、砂石、回填粘土、水泥和粉煤灰的混合土夹石作为间隙填充，逐层夯实，采用的原材料简单易得，同时使用的工程器械方便常规，通过逐层夯实后能满足溶洞填充的要求和规格，确保溶洞区域的成桩质量，有较高的填充效率和成桩质量，适合推广应用。
