Description

Technical Field

[0001] This utility model relates to the field of tunnel construction machinery technology, and in particular to a slotting device for pre-reserved slots for tunnel blind pipes. Background Technology

[0002] When tunnel projects traverse complex geological environments, problems such as groundwater leakage and accumulation of water in surrounding rock fissures can easily lead to water seepage, frost heave, or erosion of the lining structure, threatening the structural safety and operational life of the tunnel. As a core drainage facility, drainage blind pipes need to be precisely laid out through pre-reserved trenches to achieve directional drainage of groundwater. Currently, the main construction methods for pre-reserved trenches are the pre-embedded pipe method and the post-trenching method. The post-trenching method involves manually cutting the trench after the tunnel lining is poured, using handheld cutting tools to create the installation space for the blind pipe. This method is labor-intensive, slow in cutting, affects the construction progress, and easily generates dust, impacting the tunnel working environment. Utility Model Content
