Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a tunnel soil layer construction splitting grouting pipe. Background Art

[0002] In tunnel engineering, especially in the construction of urban underground transportation systems, the problem of poor geological conditions of soil layers is often encountered. These strata usually have low bearing capacity and high water permeability, which leads to construction difficulties and increased safety risks. At present, grouting is a common method for strengthening the foundation in construction projects. In the construction of subway tunnel soil layers, it is often necessary to build foundation columns or bases. At present, the grouting pipes are fixed with perforations set at equal angles around them, so that cement slurry can be radially sprayed around. In order to avoid cement slurry from being poured into non-pouring areas during construction, curtain piles must be made around the work area so that the cement slurry is limited by the curtain piles.

[0003] Traditional grouting pipes are usually connected to grouting machines. However, if the project requires it or the grouting pipe is damaged or fails to function, the grouting pipe needs to be replaced or repaired. However, in this process, it is inconvenient to replace or repair the grouting pipe, which greatly affects the work efficiency. Therefore, we propose a tunnel soil construction splitting grouting pipe to solve this problem. Utility Model Content
