At the two ends of the road or railway under construction, we will find that many guardrails are installed, but they are not only for beautiful decorative effect, but also for other safety protection effects. Because these guardrail products are generally similar to the following anti-collision guardrail boards, that is, building materials that can play a buffering role in the event of car accidents or friction problems, the materials of the products are relatively stable, and their solid performance characteristics enable them to reduce personal and property losses and safety troubles to a certain extent. Please refer to the following in advance for details.

First, the price of anti-collision guardrail plate

1, Sunac crash barrier

Company name: Maanshan Rongchuang Stainless Steel Composite Pipe Industry Co., Ltd.

Starting price:? ￥88? /meter

2. Dragonfly? Crash barrier? guardrail

Company name: Shandong Longfei Metal Material Co., Ltd.

Starting price:? ￥68? /meter

3. Taitong Traffic Hot Galvanized Wave Barrier? crash barrier

Company name: guanxian Taitong Traffic Facilities Co., Ltd.

Starting price:? ￥4200? /meter

The above prices are for reference only.

Second, the manufacturer recommended anti-collision guardrail

1, Shandong Longfei Metal Material Co., Ltd. covers an area of more than 80,000 square meters and employs nearly 100 people. Specializing in the production and sales of bridge anti-collision guardrail, anti-collision guardrail column, stainless steel composite pipe, guardrail column (steel plate column), stainless steel carbon steel composite round pipe, square pipe, rectangular pipe, oval pipe series and other new metal materials. In addition, a metal guardrail engineering production and installation company was established, which integrates production, sales, design, production and installation, and has a perfect operation mode. The company has 24 complete stainless steel and stainless steel composite pipe production lines, as well as various metal processing equipment (CNC plasma cutting machine, punching machine, scouring bed, etc. ), and has an independent zinc plating and plastic spraying workshop to handle the surface effect of steel plate. Stainless steel composite round tube, square tube, rectangular tube and elliptical tube series products have the advantages of corrosion resistance, wear resistance and beautiful appearance of stainless steel, as well as good bending strength and impact resistance of carbon steel and low price, and are widely used in landscape guardrails, bridge guardrails, collision guardrails, urban guardrails, road guardrails, pedestrian handrails, sports equipment, vehicle construction, textile machinery and medical devices.

2. Sichuan Meitong Intelligent Technology Co., Ltd. is a high-tech enterprise oriented to intelligent transportation application, specializing in core software development, intelligent transportation system integration and operation services, intelligent transportation engineering, security engineering, intelligent transportation Internet of Things data system and decision support, highway transportation facilities engineering, design and construction, R&D and related intelligent transportation products manufacturing. Has obtained a number of intelligent transportation engineering professional construction qualifications; The enterprise has passed ISO900 1:2008 product quality system and GB/T50430:2007 construction enterprise quality management system certification and ISO 1400 1:2004 environmental management system certification.

Third, what are the main points of construction?

1) The elevation measurement of the crash barrier is controlled by the elevation of the top surface of the barrier;

2) The induced joint (false joint) shall be cut by wire with a depth of 5 mm after form removal ... The deformation joint and induced joint of guardrail shall be fully considered to be unified with the template joint;

3) The top surface of guardrail must be calendered;

4) Concrete must be poured in layers, and vibration should be strengthened at the curved surface to reduce the generation of bubbles;

5) Select special release agent to ensure uniform color and smooth surface of concrete;

6) Pay attention to the reservation of embedded parts and installation notches of expansion joints when installing templates; Install the external formwork with a small wheeled cantilever portal frame and temporarily fix it;

7) Concrete curing adopts continuous drip irrigation with one cloth and one plastic;

In some public places, including both ends of railways and highways or inside hospital parks, you will find a number similar to that mentioned above. They are made of solid and reliable building materials with reasonable structural design, so they can play a buffering role in the event of a car accident, prevent vehicles from falling into the river, and further reduce personal and property losses. In addition, the late use of qualified anti-collision guardrail plates should be controlled in combination with construction steps and skills.
