Description

Technical Field

[0002] With the development of modern industrial technology, the requirements for construction projects are constantly increasing. The in-situ reconstruction and expansion of mountain tunnels requires excavation while maintaining the safety of the existing structure, and the newly poured lining often forms a complex spatial interface with the original support.

[0003] Traditional fixed concrete curing devices have multiple limitations in practical applications: their installation process is cumbersome and inefficient. Particularly noteworthy is the design of the fixed nozzle trajectory, which easily leads to curing blind spots at the joints between old and new structures. Furthermore, rigid supports are difficult to adapt to the installation requirements of the gradually changing sections of the tunnel cross-section in reconstruction and expansion projects, ultimately resulting in curing effects in different areas of the structure failing to meet standard requirements. This dual deficiency affects both construction quality and the curing efficiency of tunnel reconstruction and expansion projects.

[0004] Based on the above-mentioned technical problems, this utility model provides a concrete curing device for in-situ expansion of mountain tunnels. Utility Model Content

Both the straight section 1 and the curved section 15 are provided with spiral grooves, and the spiral grooves on the straight section 1 and the spiral grooves on the curved section 15 are connected.

[0040] In operation, this utility model first uses a support assembly to build the pipeline, and then installs the pipe head fixing assembly on the track. One end of the water pipe 9 is fixed to the pipe head fixing assembly, and the position of the nozzle is adjusted. The pipe head fixing assembly is moved along the drive track 6 by the drive wheel. The drive track 6 is arranged along the spiral groove, which can synchronously drive the end of the water pipe 9 to move along the spiral groove, thereby enabling the nozzle to move to different positions. Then, water is supplied to the water pipe 9, and the water is sprayed out through the nozzle at the end of the water pipe 9 to cure the concrete lining of the tunnel.

[0041] This invention adjusts the position of the nozzle by setting a positioning module, ensuring that the device can maintain the condition of each position. It also makes it easy to adjust the maintenance efficiency of the device according to the site environment, which greatly improves the efficiency of the maintenance device.

Finally, the position of the pipe head retainer 2 is transmitted to the controller. The controller can be set according to the specific usage environment. For example, it can be controlled by a microcontroller or by a PLC, ARM (Advanced RISC Machine), FPGA (Field-Programmable Gate Array), etc. This embodiment does not make specific limitations.

[0048] The design was further optimized so that the pipeline consists of several hollow pipe sections, which are spliced ​​together by a docking assembly. The hollow pipes have spiral grooves, and the hollow pipes at both ends are detachably connected to the support assembly.
