Karst landform cavity treatment method
The invention belongs to the technical field of cavity treatment, and discloses a karst landform cavity treatment method. The karst landform cavity treatment method comprises the steps of tunnel bottom grouting reinforcement, tunnel body primary support reinforcement, pile foundation construction, joist construction and tunnel body lining, wherein in the pile foundation construction step, construction preparation, pile casing burying and following, drilling machine installation, slurry preparation, percussion drilling hole forming construction, final hole detection, hole cleaning, reinforcement cage manufacturing and installation, underwater concrete pouring and quality inspection and testing are conducted; in the joist construction step, foundation pit excavation, foundation treatment, reinforcement and formwork construction and concrete pouring are conducted; and in the tunnel body lining step, waterproof and drainage construction, lining reinforcement construction and concrete construction are conducted. According to the karst landform cavity treatment method, targeted grouting reinforcement is conducted according to the tunnel bottom soil type, a tunnel bottom silty clay section is subjected to phi 76 steel flower tube steel tube group pile grouting reinforcement treatment, tunnel bottom karst filler is solidified, and thus the tunnel bottom safety is higher; a secondary lining mode is adopted in the tunnel body lining process, and thus firmness is higher; and a tunnel is further subjected to waterproof and drainage treatment, and thus water leakage of the tunnel can beeffectively prevented.
本发明属于溶腔处理技术领域，公开了一种用于喀斯特地貌溶腔处理方法，包括：隧底注浆加固；洞身初期支护加固；桩基施工：施工准备、护筒的埋设和跟进、钻机的安装、泥浆制备、冲击钻成孔施工、终孔检测、清孔、钢筋笼制作安装、水下砼灌注、质量检验与试验；托梁施工：基坑开挖、基础处理、钢筋、模板施工、砼浇筑；洞身衬砌：防排水施工、衬砌钢筋施工、砼施工。本发明根据隧底土壤类型进行针对性的注浆加固，隧底粉质黏土段采用Φ76钢花管钢管群桩注浆加固处理，隧底岩溶填充物固结，使得隧底安全性更高；在洞身衬砌过程中采用二次衬砌的方式，牢固性更高；还对隧道进行防排水处理，可有效防止隧道渗漏水。
