The application discloses a method for excavating a connecting channel by using a plasma torch, and the method comprises the following steps: carrying out freezing construction in a stratum until a freezing wall is closed, and the soil in the excavation path of the connecting channel is frozen into a frozen soil body; drawing an excavation contour line of the connecting channel on a working face, the excavation contour line is drawn according to the excavation path of the connecting channel, and the excavation contour line is located in the enclosure of the freezing wall; S2, drawing a cutting line on the working face, the cutting line is located in the enclosure of the excavation contour line of the connecting channel; S3, cutting the frozen soil body along the cutting line by using the plasma torch to obtain a cutting groove; and S4, inserting a nozzle of the plasma torch into the cutting groove. By reasonably designing the cutting line layout and the cutting unit area and combining the high-efficiency melting and crushing of the frozen soil body by the plasma torch, the method overcomes the shortcomings of low efficiency and great difficulty of the traditional construction method, and improves the construction efficiency and safety of the connecting channel.

The invention relates to the technical field of photovoltaic supports, and particularly discloses an anti-seismic and anti-displacement photovoltaic support which comprises a base frame, a first anti-seismic rod is arranged at the upper end of the base frame, a second anti-seismic rod is arranged at the upper end of the base frame, an anti-seismic force unloading assembly is arranged at the upper end of the second anti-seismic rod, and connecting assemblies are arranged at the upper ends of the anti-seismic force unloading assembly and the first anti-seismic rod correspondingly. A third anti-seismic rod is arranged between the base frame and the second anti-seismic rod, and the base frame, the second anti-seismic rod and the third anti-seismic rod form a triangular structure; force is effectively unloaded, springback is prevented, the hidden crack risk of the photovoltaic equipment is reduced, the secondary damage risk of springback is reduced, cooperative shock resistance is achieved, the overall stability of the photovoltaic equipment is improved, one-way dissipation and controlled reset of vibration energy are achieved, and secondary impact damage caused by instantaneous springback of a traditional spring is reduced.
