[0002] With the accelerated development of urbanization, there are more and more spatial conflicts between the planning and construction of municipal infrastructure and the overhead power lines inside and outside the city. Carrying out basic engineering construction within the protection range of high-voltage lines not only threatens the safe operation of high-voltage power lines, but also directly threatens the safety of construction workers. Therefore, it is very important to ensure safe and reliable construction under high-voltage lines, especially low-headroom high-voltage lines.

[0003] Construction within the protection range of high-voltage lines needs to keep a safe control distance in the vertical and horizontal directions, and set up a cordon. When the vertical distance between the lowest point of the 110KV high-voltage line and the ground is 18m, construction within the protection range of the 110KV high-voltage line needs to keep a safe control distance of no less than 6m in the vertical and horizontal directions, and set up a cordon at the site 10m outside the projection of the high-voltage side conductor. Therefore, when the safe construction height of the cast-in-place pile is insufficient, there are problems such as limited height of activities such as cast-in-place pile drilling, steel cage hoisting, and concrete pouring, and high construction safety risks.

The vertical network 1 is composed of two rows of lattice columns 7, a height limit rope and colorful flags 8. The two rows of lattice columns 7 are erected on both sides of the interlocking pile position 6. The horizontal network 2 is composed of a number of warning poles and colorful flags 8. A number of warning poles are erected near the interlocking pile position 6. The projection width of the high-voltage line 3 is 5m, and the vertical distance between the lowest point of the high-voltage line 3 and the ground is 18m.

[0027] Through the setting of the vertical sealing net 1 and the horizontal sealing net 2, the machinery in the construction process can be restricted from exceeding the sealing net height in the vertical direction, and the machinery exceeding the sealing net height can be restricted from entering the sealing net area in the horizontal direction. The vertical sealing net 1 and the horizontal sealing net 2 formed by the binding of the colorful flags 8 are eye-catching, which plays a good warning role, avoiding the major economic losses and adverse social impacts caused by power outages in the urban power grid due to electric shock, and also ensuring the safety of life and property on site and normal construction. The prices of materials such as the lattice columns 7, height limit ropes and colorful flags 8 that constitute the vertical sealing net 1 and the horizontal sealing net 2 are low, and the sealing nets are safe and convenient, low in maintenance cost, and can be reused, with low overall cost.

[0028] Specifically, in this embodiment, the two rows of lattice columns 7 are evenly arranged along the direction of the interlocking pile positions 6 .

[0029] The vertical sealing net 1 formed by the lattice columns 7 and the colored flags 8 can cover the interlocking pile positions 6 and limit the height of the construction machinery within the range, thereby ensuring construction safety and avoiding electric shock.

[0030] Specifically, in this embodiment, the distance between every two adjacent lattice columns 7 in the two rows of lattice columns 7 is 20 m, and the height of the lattice columns 7 is less than or equal to 12 m.

[0031] The height of the lattice columns 7 can be used to limit the height of the construction machinery within the influence range of the vertical sealing net 1 to no more than 12 m, thereby ensuring a safe distance between the construction machinery and the high-voltage line 3 .

[0032] Specifically, in this embodiment, the height limit rope is tied at the top of two rows of lattice columns 7, the height limit rope connects the two rows of lattice columns 7, and several vertical height limit ropes are evenly tied at intervals of 4m in the direction perpendicular to the lattice columns 7. The same height limit rope is tied to several vertical height limit ropes, and colorful flags are tied to several height limit ropes to ensure construction and production needs.

[0033] Specifically, in this embodiment, the height-limiting rope is an insulating Dini code rope, and the height-limiting rope and the colorful flags 8 are arranged in a criss-cross pattern.

[0034] Specifically, in this embodiment, the vertical distance between the vertical sealing net 1 and the high-voltage line 3 is not less than 6m, which can ensure a safe distance between the construction machinery and equipment near the high-voltage line 3 and the edge line of the overhead power line.

[0035] Specifically, in this embodiment, the horizontal fence 5 is set at a distance equal to 20m from the projection of the high-voltage line 3, so that the area between the vertical sealing net 1 and the horizontal fence 5 can be used as a mud pool, a steel cage stacking area, a slag stacking area and a temporary transportation channel, and certain warnings are given to large machinery and vehicles to restrict them from entering the area near the high-voltage line 3, thereby ensuring construction safety.

[0036] Specifically, in this embodiment, several warning poles in the horizontal sealing net 2 are erected at a projection extension distance of the high-voltage line 3 that is greater than or equal to 10m, and several warning poles are evenly arranged along the direction of the bite pile position 6. The distance between every two adjacent warning poles in the horizontal sealing net 2 is 20m, and the height of the warning pole is 4m. The colorful flags 8 in the horizontal sealing net 2 are tied between several adjacent warning poles.

[0037] The driving routes of large machinery and vehicles exceeding the height of the vertical sealing net 1 can be restricted to prevent them from touching the high-voltage wire 3.

[0038] The above statement is a technical solution based on the standard 110KV high-voltage line, which can be changed according to the actual numerical KV high-voltage line safety distance.

[0039] Specifically, in this embodiment, the distance between two rows of lattice columns 7 and the projection of the high-voltage line 3 is not less than 6 m.
