Filling and replacement construction method for flow-state solidified soil karst cave
The invention discloses a construction method for filling and replacing a flow-state solidified soil karst cave, which comprises the following construction procedures in the process of filling the karst cave: preparing flow-state solidified soil by taking slurry at the upper part of the karst cave as a raw material, pouring the flow-state solidified soil to the bottom of the karst cave through a pipeline, circularly extracting the slurry at the upper part of the karst cave, preparing the flow-state solidified soil and pouring the flow-state solidified soil. And stopping pouring the flow-state solidified soil until the specific gravity of the extracted slurry at the upper part of the karst cave is equal to or close to the specific gravity of the prepared flow-state solidified soil. The invention provides a construction method for filling and replacing a flow-state solidified soil karst cave, which comprises the following steps: preparing flow-state solidified soil by using original materials in the karst cave and local materials used on a construction site, pouring the flow-state solidified soil to the bottom of the karst cave, and lifting original underground water and sinking mud in the karst cave by using the fluidity and strength of the flow-state solidified soil, so as to realize filling and replacement of the karst cave. And through continuous extraction and pouring, a filling body for backfilling the karst cave is uniform and does not generate gaps, so that the backfilling quality of the karst cave is ensured.
本发明公开了一种流态固化土溶洞填筑置换施工方法，在填筑溶洞的过程中，以溶洞上部浆液为原料制备流态固化土，将流态固化土通过管路灌注至溶洞底部，循环抽取溶洞上部浆液、制备流态固化土及灌注流态固化土的施工工序，直至抽取的溶洞上部浆液的比重与制备的流态固化土的比重相等或相近，停止灌注流态固化土。本发明提供一种流态固化土溶洞填筑置换施工方法，利用溶洞内原有材料以及施工现场就地取材制备流态固化土，通过向溶洞底部灌注流态固化土，利用流态固化土的流动性与强度，抬高溶洞内原有地下水与沉底泥浆，并将二者抽取成为流态固化土的原材料，通过不断地抽取与灌注，使得回填溶洞的填充体均匀且不产生空隙，保证溶洞回填质量。
