In the construction of power transmission and transformation engineering of a power grid, a newly-built power transmission line often geographically crosses a straddled object such as an operated high-voltage power transmission line or a highway, and a ground wire of the newly-built power transmission line needs to cross the straddled object. In order to ensure a safe distance between the ground wire and the object to be straddled, an insulating safety net needs to be erected between the ground wire and the object to be straddled in advance. The safety net and its supporting device are collectively called a spanning frame.
The spanning frames adopted in the current spanning construction comprise moso bamboo spanning frames, cableway type spanning frames, frame body spanning frames and the like. The traditional spanning frames have certain defects, such as the condition that the applicable voltage level of the moso bamboo spanning frames and the scaffold spanning frames is low, the voltage level is easy to be limited by terrain and the moso bamboo quality is easy to be damaged; the cableway type crossing frame has wide application range, portability and good use, but the span between the brackets at the two ends is large, and the looseness of the cableway is reduced greatly after the cableway is subjected to impact load, so that the safety distance between the safety net and a crossed object is difficult to ensure; the automation level of the frame body crossing frame is low, the installation of the frame body crossing frame is more dependent on auxiliary lifting tools, the transportation amount is large, the installation is not convenient enough, and in the frame body erecting process, workers work aloft, and high aloft falling risks exist.

Therefore, in order to meet the construction requirements of different construction sites and improve the protection requirements of the spanning frame, a construction method of the full-protection spanning frame is needed.

s1, installing a jacking structure, fixing jacking equipment in a base, and fixing a sleeve frame on the periphery of the base;
s2, balancing the top-layer vertical frame structure, taking a sleeve frame at the highest position of a basic horizontal line as a reference, and according to measurement data, compensating the height difference of the top-layer vertical frame structures in the sleeve frames at other positions, so that the top-layer vertical frame structures are at the same horizontal position;
S3, installing an anti-falling structure, wherein anti-falling side plates are fixed on two sides of the sleeve frame, when the vertical frame structure is lifted, the rebound clamping part rotates to avoid, and when the vertical frame structure is removed from the lifting force, the square pipe frame of the vertical frame structure is arranged on the rebound clamping part;
s4, building a frame body, pushing the top layer vertical frame structure into the sleeve frame from a side gap of the sleeve frame, and lifting the top layer vertical frame structure to the top of the sleeve frame by jacking equipment, wherein the top layer vertical frame structure is limited by an anti-falling structure; the transverse frame is connected with the side edge of the top-layer vertical frame structure through the corner frame, and the transverse frame is kept at a horizontal position; the jacking equipment circularly jacks the standard vertical frame structure to be abutted to the top-layer vertical frame structure;
S5, paving a protective net, wherein one ends of a plurality of guide ropes are fixed on a transverse frame on one side, the other ends of the guide ropes uniformly penetrate through the protective net, one side of the protective net is fixed on the transverse frame on one side, and the other side of the protective net is connected with a plurality of traction ropes; the end part of the guide rope with the hook is hung on the transverse frame on the other side through the unmanned aerial vehicle, the traction rope is hung on the transverse frame on the other side through the unmanned aerial vehicle again, and the traction rope is pulled through manpower or pulling equipment, so that the protective net is pulled and paved.
9. The method for constructing a jacking full-protection crossing frame according to claim 8, wherein the method comprises the following steps: the wire pulling structure is fixed, a winch is arranged on the side edge of the sleeve frame, a hanging ring assembly is arranged at the end part of the transverse frame, the ground is fixed at one end of the wire pulling, the other end of the wire pulling winds around the hanging ring assembly to be wound in the winch, the wire pulling at the end part of the transverse frame is continuously paid off until the wire pulling is built to a proper height, the wire pulling is stopped to pay off, and the transverse frame is fixed and tensioned.
