Description

Technical Field

[0001] The utility model relates to a tool for installing a pipe segment grouting sleeve, in particular to an auxiliary installation tool for the pipe segment grouting sleeve. Background Art

[0002] During the installation of tunnel segments, there are gaps between the segments and the strata, between adjacent segments, and between the segments and the shield shell. In order to fill these gaps and increase the sealing, structural strength and stability of the underground structure, it is necessary to use grouting pipes to fill the slurry behind the segment wall. When constructing grouting pipes, workers usually use manual twisting to fix the grouting pipes at the designed position after the segment reinforcement is tied. However, this method of connecting the grouting pipes to the grouting heads by hand twisting may have some defects: the connection is not firm and there is a risk of leakage: the manual connection method may not ensure that the connection between the grouting pipe and the grouting head is firm. During the construction process, if the connection is not tight or firm enough, it may cause the grouting pipe and the grouting head to loosen or fall off, affecting the effect of grouting construction. Low construction efficiency: the hand-tightening connection method requires workers to spend more time and energy to operate, which may result in lower construction efficiency compared to other more efficient connection methods. Especially in large-scale projects, the hand-tightening connection method may increase the construction period and cost. Safety hazards: If the hand-tightening connection is not firm enough, there may be safety hazards. At the construction site, if the grouting pipe is not firmly connected to the grouting head, there is a risk of falling off or loosening, which may cause worker injuries or other accidents.
