After arriving at the site, a person with abundant experience is required to carry out overall evaluation on the surrounding environment of the lodging electric pole to determine a construction scheme, which comprises the following aspects:

1. Evaluating field work environment

The on-site water level is measured, the surrounding topography environment is observed, the construction scheme is determined, the environmental water depth exceeds 1.7 meters, the operation risk and the rail installation difficulty are too high, and the operation of a positive pole is not suitable to be carried out. According to different water levels, materials with different lengths are selected to manufacture the fence, and in the actual rush repair process, if the condition that the angle steel with the side length of 60mm is stressed and deformed is found, angle steel strips with the side length of 80mm or 100mm are adopted as materials for manufacturing the caisson on site.

2. Material preparation and fence fabrication

(1) Material preparation

Due to the bearing capacity of the ship, the fence cannot be integrally transported and installed due to the volume and the weight, fence assembly materials need to be prepared in advance, and the fence is assembled on site:

a) Punching angle steel bars 211 forming the fence 21 according to a designed position, cutting a tip end with an oblique angle of 30-45 degrees at the bottom so as to insert the tip end into the ground below the water bottom, and fixing and assembling the angle steel bars 211 by screws or welding and assembling the angle steel bars 211 on site by using the connecting steel bars 212;

b) A material with proper toughness is selected as a traction stay rope, and the length of the stay rope is generally not less than 1.5L (L is the length of a lodging tower), so that the traction device 11 applies a pulling force to the rod body 1;

c) As the fixture 22, sand bags, stones, etc. to be easily transported are prepared, transported to the rail 21 by a ship, and put into the rail 21 to form the anchor assembly which is not easily pulled.

(2) Manufacturing fence

The personnel take the boat to reach the appointed repair position, wear whole body water suit and get into the aquatic and form a rail 21 with 2-3 meters long angle steel through welding or bolted connection, will rail 21 nail into the submarine underground more than 1.2 meters (be greater than half of angle steel strip 211 total length to keep it not take place the displacement), put 40 sand bags/sand stones about 1.2 tons in the steel cage and weigh, use as the temporary earth anchor of dead lever. To ensure that the sandbag is not flushed away by water, the angle bar 211 generally needs to extend above the water surface a certain distance.

In order to pull up the rod 1 more easily and keep the pulled up state of the rod 1 in the water jet, the rail is provided in such a manner as shown in fig. 2 that a plurality of (generally only two) anchor assemblies are provided around the rod 1 at different positions relatively upstream positions, so that the rod 1 can be pulled up and kept in the pulled up state more easily according to the triangular stable structure.

In hoisting machinery, wire jackets are often used to secure the wire rope to avoid damage to the wire rope from abrasion or friction with other objects during movement.

2. The vertical rod body scheme is selected: according to the inclination angle of the lodging pole and the horizontal plane, whether the supporting rod 14 shown in fig. 1 is needed to be used in the process of correcting the pole is judged. The length of the supporting rod 14 is greater than the height from the bottom of the rod body 1 to the position where the supporting rod is connected by the pull rope 12, so that the pulling force for pulling the rod body 1 is changed from the overall downward direction to the overall upward direction, and the gravity applied to the rod body can be overcome, so that the rod body 1 can be pulled up more easily.

3. Correcting the rod body 1

Attention is paid to the following points:

a) The operator can tighten the pull rope 12 by controlling the tractor 11 to gradually correct the rod body 1. Before correction, the fixing drill rod 13 is nailed into the heel part of the rod body 1 for 2 meters so as to fix the root part of the rod body 1 at the original position, and the rod body is prevented from being displaced in the correcting process and after the correction is completed.

B) The rod body 1 needs to be held tightly by the oil silk sleeve 15, a support is arranged at the bottom of the connecting position of the rod body 1 and the oil silk sleeve 15, sand bags are continuously stacked around the fixing drill rod 13 for reinforcement, and the fixing drill rod and the anchoring assembly ensure that the rod body 1 is firm. So as to prevent the rod body 1 from shaking or tilting during the lifting process.

C) After the rod body 1 is corrected, the inclination angle is generally within a safe and reasonable range (generally 85-90 degrees) depending on the water flow direction, so that the requirement that the power supply line is far away from the water surface can be ensured, and the stable state of the current inclination angle can be maintained through the pulling action of the upstream anchoring assembly.
