Soil dissolving hole treatment construction method
The invention discloses a soil dissolving hole treatment construction method, and relates to the technical field of soil dissolving hole construction, and the method comprises the following steps: S1, hole arrangement and pipeline installation; s2, grouting is conducted; and S3, pile casing follow-up is carried out. According to the method, a method of combining steel casing follow-up and rubble and clay filling is adopted for small and medium soil dissolving holes, a method of combining steel casing follow-up and pre-grouting is adopted for large and ultra-large soil dissolving holes, and the problem of how to quickly and safely carry out pile foundation construction in karst development areas close to existing bridges, pipelines and the like is effectively solved.
本发明公开了一种溶土洞处理施工方法，涉及溶土洞施工技术领域，步骤包括：步骤S1：布孔及安装管道；步骤S2：注浆；步骤S3：护筒跟进。本发明通过对小、中型溶土洞采取钢护筒跟进及片石与粘土填充组合的方法，对大型、超大型溶土洞采取钢护筒跟进和预注浆组合的方法，有效的解决了岩溶发育地区临近既有桥梁、管线等如何快速安全的进行桩基施工的难题。
