古田岭里水库土坝涵洞周边高喷加固处理方法

高压喷射灌浆是土坝防渗加固最常用、技术相对成熟的方法之一,但在实际施工中,位于坝体较高部位的涵洞处理一直是个难题。福建古田县岭里水库土坝高喷加固处理时,通过精确布孔、钻孔,结合采用各种喷射的灵活组合和喷嘴方向的调节等措施,使得涵洞周边喷灌质量达到了土坝除险加固的规范要求。现场静水头压水试验证明古田县岭里水库土坝总体防渗效果较好。实践证明古田县岭里水库采用的土坝高喷加固涵洞周边处理方法对类似工程具有一定的参考与借鉴价值。

The High Pressure Spouting and Strengthening Treatment Method around the Culvert of the Gutian Lingli Reservoir

High pressure spouting grouting is one of the most common and mature methods in the seepage control and strengthening of the earth fill dam.Actually,how to treat the culvert in a higher position of the dam is a problem.When they carry out the high pressure spouting and strengthening treatment in Fujian Gutian lingli Reservoir,they take various measures,such as accurate interstices and drillings,adopting various spouting methods and adjusting the nozzle directions,which makes the sprinkler irrigation quality around the culvert meets the stand requirements to reinforce the earth fill dam.The site static head pressurized test indicates that the high pressure spouting and strengthening method which Gutian Lingli Reservior adopts to treat the culvert has a good result,which has some reference values for similar projects.
