Single-point settlement monitoring hole backfilling device and backfilling method
The backfilling device comprises a liquid pump assembly, the slurry suction end of the liquid pump assembly is connected with a filling slurry stirring container through a pipeline, the slurry discharge end of the liquid pump assembly is connected with the top of a connecting rod through a pipeline, and a slurry discharge hole is formed in the bottom of the connecting rod. The backfilling method comprises the following steps: drilling a monitoring hole; temporarily sealing the hole; expanding the orifice to form a top anchoring end backfilling groove; excavating a monitoring hole residual slurry discharge groove; temporary hole sealing is canceled; opening a slurry discharge hole; forming a connecting rod; the connecting rod is arranged in the monitoring hole; communicating a liquid pump assembly; installing a filling slurry stirring container; performing anti-seepage protection treatment; preparing filling slurry; filling slurry is injected; cleaning the slurry; the overflow condition is observed; installing a displacement sensor; and carrying out equipment debugging and field protection. The backfilling compaction of the monitoring hole can be ensured, and the reliability of monitoring data is improved.
本发明公开了一种单点沉降监测孔回填装置及回填方法，其回填装置包括液泵组件，液泵组件的浆液吸入端与填充浆液搅拌容器通过管线连接，液泵组件的浆液排出端与连接杆顶部通过管线连接，连接杆底部设置浆液排出孔。其回填方法，包括以下步骤：钻监测孔；临时封孔；扩大孔口形成顶部锚固端回填槽；开挖监测孔残留泥浆排出槽；取消临时封孔；开浆液排出孔；组成连接杆；连接杆装入到监测孔；连通液泵组件；安装填充浆液搅拌容器；进行防渗保护处理；配置填充浆液；注入填充浆液；清理泥浆；观察溢出情况；安装位移传感器；进行设备调试和现场保护。本发明能够保证监测孔回填密实，提高监测数据可靠性。
