Safety protection scheme for the hottest high volt

  • Detail

High voltage line tower safety protection scheme

the tensile testing machine for plot a project of Xuzhou Gulou square comprehensive development project fully develops the expertise of each motor. The large-scale fine testing instrument is located in Xuzhou City, Jiangsu Province, and the project is about 2.5 kilometers away from the urban area of Xuzhou. To the west of the project is Zhongshan North Road, the main commercial road, and to the north is the Second Ring North Road, with convenient transportation

the project consists of 13 residential buildings, of which the 367899 tower has 34 floors above the ground, and the total height of the building is 99.05 meters; 1 245tower has 33 floors above the ground, and the total height of the building is 96.15m; The above ground structures of 10 ; The above ground structures of the 13 \e tower are all 6 floors, and the total height of the building is 19.60m. The above ground building area of the project is 146750.90m ⊃;, The total building area is 197173.90m ⊃;. This scheme is a safety protection scheme prepared for the construction of pile foundations of 3 -, 7 -, and 8

2.1 the protective frame is about 11m long, 6.5m wide and fully covered

2.2 all protective frames shall be made of Moso bamboo. The longitudinal distance (span) of vertical poles shall be 0.9m, the horizontal distance between vertical poles shall be 0.6m, and the step distance of vertical poles shall be 1m. The first longitudinal and horizontal horizontal poles shall be 15cm above the ground as sweeping poles. The safety distance between the protective frame and high-voltage lines and poles shall not be less than 1.5m. The specific details are attached:

2.3 the protective frame shall be fully hung with dense mesh for safety, and the top shall be paved with safety bags. The above two kinds of safety must be firmly and reliably hung, The pocket shall be tightened horizontally on the top surface to ensure that each point of the pocket is more than 1.5m from the top of the high-voltage line or pole

all protective frames are set up with moso bamboo. Bamboo sticks and thick bamboo pieces are used to closely connect the Moso bamboo that cross or overlap each other. The annual sales volume of bamboo sticks reaches 500000. The diameter is not less than 6mm, and the length is not less than the diameter of the passing Moso Bamboo pole. The thickness of the bamboo piece is not less than 5mm, and the width is not less than 8cm. The length should ensure that each side of the two connecting rods is not less than 10cm, the diameter of the small end of the Moso bamboo pole is not less than 8 cm, and the cross bar is not less than 7 cm, The holes of bamboo chips and moso bamboo poles shall all be drilled with a manual electric drill of appropriate diameter, and the end of the bamboo stick shall not be exposed outside the bamboo pole

3.2.1 the longitudinal horizontal bar shall be erected outside the vertical bar. When erecting the first step of longitudinal horizontal bar, the first longitudinal and horizontal horizontal bar shall be 15cm above the ground as the sweeping bar, and the verticality of the vertical bar must be ensured. When erecting the longitudinal horizontal bar, people must cooperate with the operation. One person in the middle shall connect the bar, lay it flat, and connect and nail it from the big end to the small end

3.2.2 the diagonal bracing shall be close to the vertical pole, and then the personnel above shall nail the diagonal bracing and the vertical pole with a nail hammer and a bamboo stick. The rafters on the pile (capping) of the diagonal bracing shall face upward, and the vertical pole shall be nailed to the longitudinal horizontal pole. The diagonal bridging is at an included angle. The diagonal bridging is evenly distributed in 3 rows in the longitudinal direction (four rows in the longitudinal direction). A row of diagonal bridging is set for every 2 rows of vertical poles in the transverse direction (one row is arranged at the other two ends). The longitudinal and transverse diagonal diagonal bridging is erected from the top of the protective frame to the bottom of the protective frame. The diagonal bridging should avoid the transformer and the electric pole

astm G105 SAE Recommended Practice (Falex dry sand/rubber wheel apparatus) and other standards 3.2.3 the effective lap length of two rod connection shall not be less than 1.5m. The lap joint of two rods shall be nailed symmetrically and evenly on both sides with thick bamboo slices. The lap points of adjacent two rods must be staggered. The horizontal and oblique rod connections shall be made. The small end shall be pressed on the big end. See the connection node 1 and 2 drawings of rod and rod for the connection details of the lap joint

3.2.4 the methods and means of up, down, left and right calibration are basically 1. When transferring the bamboo pole, the operator should coordinate and cooperate, pay attention not to collide with the upper personnel and the connected pole, and the lower pole handing personnel should not let go until the upper personnel catch the pole

3.2.5 when two poles cross, they must be firmly connected, and the bamboo pole must not touch the empty line of the external power frame

3.2.6 when the pole height exceeds or approaches the high-voltage line during erection, two ropes shall be pulled at the upper end of the bamboo, and one person shall pull it at the side away from the high-voltage line to prevent the bamboo from toppling towards the high-voltage line

3.2.7 in case of underground obstacles at individual upright poles, the pole may not be erected first. After other upright poles are erected, the sweeping pole and the first step horizontal pole shall be nailed on two horizontal poles. If two consecutive upright poles or the shelf end upright poles cannot be erected normally, two auxiliary upright poles shall be erected to connect with the horizontal pole
