Corrugated guardrail is a common traffic safety facility, which is widely used on both sides of highways, primary roads, secondary roads and other roads, aiming to reduce the occurrence of traffic accidents and ensure the safety of pedestrians and drivers. The following will introduce the construction plan and technical measures of the corrugated guardrail.
First, the basic concept of corrugated guardrail
The corrugated guardrail consists of a series of corrugated beam plates, usually made of galvanized steel or aluminum alloy plates, which are fixed on both sides of the road by connectors and columns. The corrugated beam plate has good bending stiffness and bearing capacity, which can effectively absorb the energy of the vehicle during collision and reduce the damage to the vehicle and the injury to personnel. The appearance of the corrugated guardrail is simple and beautiful, and it also has a certain anti-glare and induces the effect of sight, which improves the traffic safety and comfort of the road.
Second, the corrugated guardrail construction plan
1. Construction preparation.
Before construction, it is necessary to make full technical and material preparations. Technical preparation includes familiarity with design drawings, understanding of construction specifications and related technical requirements, conducting site surveys and measurements, etc. Material preparation includes the procurement of qualified corrugated beams, plates, connectors, columns and other materials, and ensuring that the quality of the materials meets the design requirements.
2. Foundation construction.
The foundation construction of the corrugated guardrail includes column burial and concrete pouring. When burying the column, the position and depth of the column should be determined according to the design requirements to ensure the verticality and stability of the column. When pouring concrete, the concrete should be prepared according to the number and proportion required by the design, and the compactness and strength of the concrete should be ensured.
3. Corrugated beam plate installation.
The installation of corrugated beams and slabs is a key link in the construction of corrugated guardrails. Before installation, the quality and specifications of the corrugated beam plate should be checked to see if they meet the design requirements, and they should be numbered and positioned according to the design drawings. During installation, the corrugated beam plate should be fixed to the column with suitable connectors, and the horizontal and vertical degree of the beam plate should be ensured. At the same time, the connection between adjacent beams and plates should be tight and smooth, and there is no obvious height difference.
4. Acceptance and maintenance.
After the construction is completed, the acceptance work should be carried out to check whether the indicators of the corrugated guardrail meet the design requirements. For the parts that do not meet the requirements, they should be rectified in time. In the process of daily use, the corrugated guardrail should be regularly maintained and maintained to maintain its good use condition and appearance quality.
Third, the corrugated guardrail technical measures
1. Material selection.
The selection of high-quality corrugated beams, connectors and columns is the prerequisite to ensure the quality of corrugated guardrails. Materials with good corrosion resistance, aging resistance and impact resistance should be selected, and the quality and specifications of the materials should be ensured to meet the design requirements.
2. Construction process control.
In the construction process, the construction technology and operating procedures should be strictly controlled to ensure that the construction quality of each link meets the requirements. For key parts and important processes, quality inspection and control should be carried out to prevent quality problems and potential safety hazards.
3. Optimization of technical measures.
In the construction process, the construction plan and technical measures should be optimized and adjusted according to the actual situation. For example, for road sections with complex terrain, the position and depth of the columns should be adjusted according to the actual situation to ensure the stability and safety of the corrugated guardrail.
Corrugated guardrail is one of the important facilities to ensure road traffic safety. In the actual construction process, the basic concept and construction requirements of the corrugated guardrail should be fully understood, the construction technology and quality should be strictly controlled, and the technical measures should be optimized and adjusted in combination with the actual situation. Only in this way can we ensure the construction quality and use effect of the corrugated guardrail, and provide a strong guarantee for road traffic safety. Corrugated guardrails
