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.
⑤Caution should be exercised during the guardrail installation to avoid damaging any buried facilities such as cables and pipes beneath the road surface.
In highway guardrail installation projects, once road construction and pile work are completed, the installation and construction of the guardrail panels with a wavy design can begin. Prior to the start of the guardrail panel installation, a test section of several dozen meters must be set up to ensure quality and gain experience. Only after obtaining the engineering supervisor's approval can the full-scale installation proceed. Below are the requirements and steps for the installation of guardrail panels with a wavy design.
Installation of Highway Guardrails: 2. Vertical Alignment: First, draw lines on the curbs using a red pencil at the spacing of the posts, then lay a line using rope and nails along the road direction, adjusting the line continuously. Next, find a vertical line perpendicular to the parallel line on the line, then find a vertical line perpendicular to the horizontal line on the horizontal line. Place a line along the horizontal line in the direction of the horizontal line, ensuring the horizontal line is perpendicular to the horizontal line.
3. Control Column Height: The stability of the decorative column ceiling determines the stability of the guardrail panel wall, which in turn dictates the height of the columns as a high factor in preventing collision line damage. During the initial construction process of the collision prevention columns, we assume that the curb stones are undoubtedly at the designated elevation, as per the construction drawings, with the architectural elevation of the column wall exceeding the curb stone by 1750 px. When driving in a column, each column is set at the designated elevation, as per the construction drawings, with one wall height exceeding the curb stone by 1750 px. Then, after each column is driven, when the pile hammer falls on a column, each column must be struck until it reaches the next column. This process is repeated until the column height is achieved. For the construction of highway guardrails, the column height is adjusted based on the construction drawings, ensuring that each column is sufficiently high.
The coated guardrail panels can have a lifespan of several decades under natural conditions. The guardrail with corrugated beams is typically categorized by the installation location and collision resistance grade. By installation location, they can be divided into roadside guardrails and median divider guardrails. By collision resistance grade, they usually fall into Aji and B grades. Aji guardrails are reinforced and suitable for particularly dangerous roadside sections, while B-grade is used for highways. To expand industrial transfer and development space, the large-scale development of the environmental protection industry can increase the supply of scarce resources while also expanding the market space for economic growth.
