Temporary Fence

1. The construction site fence network shall be implemented as soon as possible after the completion of the roadbed project; the contractor shall formulate a detailed application plan for the supervision engineer before the construction. The contractor shall, according to the approved construction organization design, carry out the construction and lofting according to the requirements of the drawings and the actual terrain and features, determine the centerline of the column, carry out the necessary clearing and excavation of the roots to construct the barrier according to the specified slope and line shape. 

2. The burying of the column should be carried out in sections. First bury the columns at both ends, then pull the wires to bury the middle columns. Viewed from the longitudinal direction, the axis of the column should be in a straight line. There must be no uneven phenomenon: from the height point of view, the top of the column should be smooth and there should be no unevenness.

3. If there is a break in the Palisade Fencing or at the intersection of roads, the spacing of the columns may be adjusted as needed. When crossing the river, when the width of the river is not more than 6m, it should be connected as shown in the drawings or with barbed wire; when the width of the river is greater than 6m, the barrier should be closed and connected.

4. When the drawings require that the columns, supports or heads be buried in the concrete foundation, the contractor shall install the necessary temporary cables or supports to hold the columns in place until the concrete hardens. Concrete regimen during 7d. No material or parts should be installed or tightened on the columns, cables and supports. All columns shall be laid vertically in accordance with the drawings and lines.

All mesh and wire shall be tight and not deformed, and the installation height shall comply with the drawings. After the isolation barrier is installed, the foundation of the column needs to be compacted.

6. Where the high-voltage transmission line passes through the installation barrier, the isolation booklet shall be connected to the ground wire as specified by the power department. When the wires are parallel or nearly parallel to the isolation barrier and the wires are above the isolation barrier, ground wires should be buried at each end or at a spacing of no more than 400 m, with a grounding resistance of less than 102 (ohms).

7. The barrier should be set along the terrain. If necessary, geotechnical leveling is required to achieve a neat appearance. In low-lying areas. When the vertical profile of the ground is abrupt and cannot maintain the specified net height from the ground, a longer column can be used and then multiple strands of barbed wire can be pulled. The vertical clearance between the barbed wires is equal to or less than 150 mm. After excavation or drilling, all columns shall be buried as approved. Generally, the column should be slanted on both sides of the column every 100m to ensure its stability: where the barrier is in the direction of change, the column should be provided with three-way diagonal support.

8. The protective net on the bridge shall be installed as shown on the drawings and firmly installed on the column or support; the metal mesh shall be stretched and tightened, and the entire structure shall not be distorted.

The above is the introduction of the guardrail installation requirements for the Boundary Fence Supplier, I hope to help everyone.
