Double-ring-hoop-shaped grouting reinforcement structure for tunnel underneath passing existing pipeline and construction method of double-ring-hoop-shaped grouting reinforcement structure
The invention discloses a double-ring-hoop-shaped grouting reinforcement structure for a tunnel to pass through an existing pipeline under the tunnel and a construction method of the double-ring-hoop-shaped grouting reinforcement structure. Comprising an arc-shaped curing belt located below a pipeline, a semicircular grouting reinforcement area connected with the arc-shaped curing belt and wrapping the pipeline, and a grouting isolation belt half surrounding the pipeline, and the grouting isolation belt is formed by grouting and filling a semicircular grouting channel in the grouting isolation belt with composite fiber ultra-high performance cement grouting materials. According to the method, a micro-disturbance non-excavation grouting reinforcement technology is adopted, so that an earth body covered on the underground pipeline does not need to be excavated integrally, and the pipeline reinforcement cost is greatly saved; the method is very suitable for urban areas with dense population and depopulated areas with complex terrains, has little influence on natural landscapes such as surrounding stratum landforms and vegetation sceneries, has a certain environmental protection effect, and is particularly suitable for key engineering pipeline reinforcement construction of underground large-diameter super-long pipelines under other construction disturbance.
本申请公开了一种隧道下穿既有管线的双环箍形注浆加固结构及其施工方法，该结构包括双环箍形注浆加固区，包括位于管道下方的弧形固化带、与所述弧形固化带连接并包裹所述管道的半圆形注浆加固区以及半包围所述管道设置的注浆隔离带，所述注浆隔离带是通过在其内的半圆形注浆通道内注浆填充复合纤维超高性能水泥注浆料而成。本申请通过采用微扰动非开挖注浆加固技术，无需整体开挖地下管道上覆土体，极大节约管道加固成本；无论是在城区人口密集处，还是在地形复杂的无人区都极为适用，且对周边地层地貌、植被风景等自然景观影响甚微，具有一定的环境保护作用，特别适用于地下大直径超长管道在其他施工扰动下的重点工程管道加固施工。
