Embodiment 1

[0039] A four-layer multi-block tunnel shotcrete operation planning method for an automatic wet spraying machine, the planning method comprising the following steps:

[0040] Step 1: Shotcrete of the rock surface layer is to pretreat the original rock surface formed by blasting;

[0041] Step 2: On the basis of step 1, the bottom layer shotcrete is performed, starting from the rock surface until the area behind the covered steel arch is shot;

[0042] Step 3: On the basis of step 2, the core layer is sprayed, and the middle of the adjacent steel arch is sprayed on the basis of the bottom layer shotcrete;

[0043] Step 4: On the basis of step 3, spray the leveling layer, and continue to spray concrete with a thickness of 3 cm on the basis of the completion of the core layer spraying.

[0044] Further, the step 1 is specifically to fill up the pit on the original rock surface, and the method used in the shotcrete operation of the rock surface layer is to spray at a fixed attitu...

Abstract

The invention discloses a four-layer multi-block tunnel spraying operation planning method for an automatic wet spraying machine. Step 1: Shotcrete on the rock surface, which is to pretreat the original rock surface formed by blasting; Step 3: On the basis of Step 2, spray the core layer, and spray the middle of the adjacent steel arches on the basis of the bottom layer shotcrete; Step 4: On the basis of Step 3, carry out the shotcrete for the leveling layer , On the basis of the completion of the core layer shotcrete, continue to spray concrete with a thickness of 3cm. The present invention aims to solve the technical problem that the above-mentioned existing tunnel spraying operation method cannot meet the operation requirements of an automatic wet spraying machine.

Description

technical field [0001] The invention belongs to the field of tunnel construction, and in particular relates to a four-layered multi-block tunnel shotcrete operation planning method for an automatic wet shotcrete machine. Background technique [0002] At present, most of the tunnel shotcrete operations are manually controlled shotcrete robotic arms. The operating environment is extremely harsh, the working conditions are poor, and the process takes a long time, which seriously endangers the health of workers, and the quality of the completion is poor, which cannot meet the high efficiency and high surface area of ​​tunnel support. quality requirements. The automatic wet spraying machine currently being developed can solve the above problems well, but the traditional manual spraying operation method cannot meet the operation requirements of the automatic wet spraying machine. SUMMARY OF THE INVENTION [0003] The present invention provides a four-layered multi-block tunnel ...
