④When purchasing, pay attention that the packaging and labeling of the high-strength bolt connections at the wave beam should comply with the relevant provisions of GB/T1231.
⑤Exercise caution during guardrail construction. Choose a reputable guardrail panel installer and do not damage any buried utilities such as cables and pipes beneath the road surface.
In highway guardrail installation projects, after roadwork and pile operations are completed, the installation and construction of the guardrail panels with a wavy design can commence. Prior to the start of guardrail panel installation, a test section of several dozen meters must be set up. Only after achieving quality and experience results and obtaining approval from the project supervisor can the full-scale installation proceed. Below are the requirements and steps for the installation of guardrail panels with a wavy design.
In recent years, with the rapid development of domestic highway construction, the market for road guardrails has been expanding significantly. The position of guardrail posts is determined as follows: first, draw horizontal lines on the kerb using a marker according to the post spacing, then use measuring equipment to fit the overall smooth line shape based on the kerb and shoulder edge lines, and insert some lines using string and nails along the road and slightly upwards. Repeat the adjustment of the line shape to as closely match the overall line as possible. Finally, draw vertical lines perpendicular to the horizontal lines on this line, forming a cross, which serves as the center of the post position. When driving in the posts, strictly align them with the cross to ensure the posts maintain fundamental straightness in the longitudinal direction.
Edge stones do not produce errors in either the longitudinal or transverse directions. Therefore, only by aligning the posts according to the edge stones can we ensure that the laying direction of the protective net along the longitudinal (road) direction will not have any errors. Consequently, there will be no errors in the laying direction of the edge stones along the longitudinal (road) direction, and the protective net will not have any errors in the transverse direction. There will be no deviations in either the longitudinal or transverse directions. 1. First, determine the post spacing, using highway bridges, movable protective net openings, safety exits, elevated roads, and level crossings as laser distance measurement standards. The post spacing is either 2 meters or 4 meters, with 2-meter spacing for elevated posts and 4-meter spacing for standard posts. In actual construction, irregular spacing often occurs, and the installation location of the irregular panels is uncertain due to the undefined spacing. Therefore, when determining the post spacing, it is best to avoid irregular spacing.
