Problems solved by technology
The existing fixed pre-buried channel technology is to use binding wires or directly open holes on the formwork to fix the channels. The technical disadvantage of using binding wires is that after the channels are fixed on the steel mesh with binding wires, the position of the channels is not easy to adjust. Ensure the accuracy of the pre-embedded position of the channel; the technical disadvantage of directly opening a hole on the formwork to fix the channel is that the formwork only has one positioning hole, it is not easy to find the channel, and there is no way to stop the slurry

The invention discloses a fixed installation structure and method for a pre-buried channel in a mine digging method trolley. The fixed installation structure for the pre-buried channel in the mine digging method trolley comprises the channel, a trolley template, positioning nuts, T-shaped bolts, grout stopping insertion pieces and anchor rods. The anchor rods are installed on the back of the channel, positioning holes are formed in the trolley template, the positioning nuts are welded to the trolley template, U-shaped grooves are formed in the positioning nuts, the T-shaped bolts penetrate through the positioning nuts and the positioning holes in the trolley template, the grout stopping insertion pieces are inserted into the trolley template through the U-shaped grooves in the positioning nuts and the positioning holes, grout stopping plugs are arranged on the grout stopping insertion pieces, the grout stopping insertion pieces plug the positioning holes in the trolley template through the grout stopping plugs, and the anchor rods on the back of the channel are fixed to rebars through insulating binding wires. The fixed installation structure and method are convenient to use, installation is simple, and installation steps are simplified.
Description
technical field [0001] The invention relates to the technical field of channel installation methods, in particular to a structure and method for fixing and installing a pre-buried channel on a mining trolley. Background technique [0002] The pre-buried channel can be used in subway, high-speed rail, intercity and other urban rail transit projects, and can also be used in housing construction, water conservancy and hydropower, nuclear power, comprehensive pipe gallery and other projects; the application of pre-buried channel technology, the way of pre-buried channel Instead of the traditional way of chemical anchor bolts and metal brackets, it can greatly facilitate the installation of equipment and pipelines in the later stage, making the layout of equipment and pipelines convenient and flexible, greatly improving the on-site installation and construction environment, and can efficiently improve the installation work efficiency and shorten the construction period. And it ca...
