Earth surface deep layer grouting process
The invention provides an earth surface deep layer grouting process. A drill rod retreating type 30 meters earth surface deep layer grouting method is adopted, the pre-grouting reinforcement and the tunnel excavation are separated, grouting and excavation are synchronously carried out, when the method is adopted for earth surface deep layer grouting, the construction period can be remarkably shortened, and the earth surface grouting effect can be revealed through grouting effect verification and test section excavation in combination with temporary road occupation of road traffic, earth surface pipeline distribution, precise hole distribution and precise control area grouting. The earth surface deep layer grouting process has the advantages of being efficient and rapid in grouting, outstanding in effect and the like, separation of stratum grouting pre-reinforcement and tunnel excavation is achieved, the grouting operation environment is guaranteed, occupational health of grouting workers is facilitated, and the better application prospects are achieved.
本发明提供了一种地表深层注浆工艺，采用钻杆后退式30m地表深层注浆方法，将预注浆加固与隧道开挖分离，实现了注浆与开挖双同步进行。采用本发明所述方法进行地表深层注浆，不仅能够显著缩短施工工期，还能结合道路交通临时占道、地表管线分布，精准布孔和精准控域注浆，经注浆效果验证和试验段开挖揭示地表注浆效果。本发明提供的地表深层注浆工艺具有注浆高效快捷、效果突出等特点，实现了地层注浆预加固与隧道开挖的分离，保证了注浆操作环境，便于注浆工人的职业健康，具有良好的应用前景。
