Pile wall fissure-shaped karst cave blocking method
The invention discloses a plugging method for a pile wall fissure-shaped karst cave, which comprises the following steps of: S1, accurately and detailedly exploring the size and depth of an exposed karst cave so as to determine a treatment scheme of the karst cave; s2, after a construction scheme is determined, necessary materials and construction machines such as telescopic steel pipes, expandable foam sprayers, wood formworks and air bags are prepared; s3: a, a crack-shaped karst cave with an upward trend: obliquely drilling a hole in the karst cave at a certain distance above an opening of the upper karst cave until the karst cave is opened, meanwhile, supporting a mold at the opening of the karst cave to seal the karst cave, reserving a hole in a template at the opening of the upper karst cave, and densely filling a gap between the template and the opening of the karst cave by using an expandable foam spray; and b, the downward crack-shaped karst cave is formed, specifically, a telescopic spring steel pipe extends into the karst cave by a certain distance through a tool to be supported, the problem that in the pile construction process, the karst cave is encountered can be solved, the construction period can be shortened, manpower and material resources can be saved, and engineering construction can be conducted smoothly.
本发明公开了一种桩壁裂隙形溶洞的封堵方法，其包括：S1：对暴露出的溶洞大小、深度进行准确详细勘探，从而确定溶洞的处置方案；S2：确定施工方案后，准备好可伸缩式钢管、可膨胀式泡沫喷剂、木模板、气囊等必要材料和施工机具；S3：a.走向朝上裂隙形溶洞：在上侧溶洞口上方一定距离，斜向溶洞钻孔，直至打通溶洞，同时在溶洞口支模将溶洞封住，并在上侧溶洞口处的模板预留一个孔洞，利用可膨胀式泡沫喷剂将模板与溶洞口间的缝隙填充密实；b.走向朝下裂隙形溶洞：利用工具将可伸缩式弹簧钢管伸入溶洞内一定距离支撑住，本发明能够解决桩施工过程中遭遇溶洞的有害情况，能够加快工期，节省人力物力，使工程施工顺利进行下去。
