Karst cave pouring and backfilling construction method for flow-state solidified soil
The invention discloses a karst cave pouring and backfilling construction method for flow-state solidified soil. The filling process comprises the steps that S1, site muck sampling is conducted, the ratio of muck to a curing agent is determined after an underwater pouring test, the collected muck is stirred, and after the curing agent is added, the flow-state solidified soil is formed; s2, a pouring hole and an exhaust hole of the karst cave are formed, a measuring rope is vertically placed, and the depth and the water level height of the karst cave are measured; s3, the steel guide pipe is inserted into the bottom of the karst cave, a steel funnel is arranged above the pouring hole, the steel funnel is connected with the steel guide pipe, and flow-state solidified soil is conveyed into the karst cave through the steel funnel; s4, after the fluid-state solidified soil is solidified, hardened and formed, core pulling sampling is conducted, and strength detection is conducted. According to the karst cave pouring and backfilling construction method for the flow-state solidified soil, the flow-state solidified soil is used for pouring the karst cave, the tamping action is avoided, and due to the fact that materials are taken from an existing construction site, the muck outward transportation cost and the material cost can be effectively reduced.
本发明公开了一种流态固化土的溶洞灌注回填施工方法，填筑过程包括：步骤S1.现场渣土采样，经水下灌注试验后确定渣土与固化剂之间的比值，将采集的渣土搅拌、添加固化剂后形成流态固化土；步骤S2.设置溶洞的灌注孔与排气孔，垂放测量绳，测量溶洞深度与水位高度；步骤S3.钢导管插入溶洞的底部，并在灌注孔上方设置钢漏斗，钢漏斗连接钢导管，通过钢漏斗向溶洞内部输送流态固化土；步骤S4.待流态固化土凝固硬化成型后，抽芯取样并进行强度检测。本发明提供一种流态固化土的溶洞灌注回填施工方法，使用流态固化土浇注溶洞，避免了夯实动作，且由于是现有施工地取材，能够有效减少渣土外运成本与材料成本。
