highway guardrail tools is an important part of the road safety facilities. Its main function is to prevent the vehicle from getting out of the road and through the central separation belt, thus reducing the severity of the accident.

In order to prevent the vehicle from getting out of the road or breaking into the direction of the lane, it is necessary to require the guardrail to have enough mechanical strength to resist the collision of the vehicle and protect the personnel from the damage. The structural forms of guardrails mainly include semi rigid guardrails, rigid guardrails and flexible guardrails. Each form has its adaptability. At present, it is widely used as a semi rigid guardrail.

Wave beam guardrail is a common form of semi rigid guardrail. It has a certain stiffness and toughness. It mainly absorbs energy through the deformation of the beam, column and soil foundation. It is easy to replace the damaged part and has a certain line of sight induction.

Corrugated highway guardrail tools is composed of wave guardrail, column, bracket, block, end, fastener and foundation. The material of the barrier plate, column and resistance block are ordinary carbon structural steel. The material of the splicing bolt is No. 45 steel, 20TiB steel, nut 35 steel, the washer is flat steel and strip steel, and the connecting bolt is ordinary carbon steel. All parts of the guardrail must be treated with anticorrosion.

The testing items of the wave beam guardrail are four parts of appearance quality, geometric shape and size, steel plate material performance and coating quality. The sampling method should be based on sampling standard, and the test method is based on GB700JT/T 281. The quality inspection after installation mainly includes horizontal alignment, geometric size and strength performance.

highway guardrail tools is a wall guardrail structure with a certain cross-section shape, which belongs to a rigid guardrail. The concrete guardrail is made of cement, gravel, water and steel bar. The concrete guardrail formwork is an indispensable and important tool in the prefabrication process. It directly affects the quality of precast concrete and needs to check the size and quality of the steel formwork. The quality of the concrete base course affects the quality after installation, and the quality of the base should be checked according to the specifications. The appearance quality and geometric size of concrete guardrail must be tested.

The cable guardrail is a flexible guardrail twisted by wire rope. According to the location, two categories can be divided into the roadside and the central divider. The embedment conditions can be divided into two categories: buried in the road and concrete. The concrete foundation can not be inserted into the columns and the depth of the columns can not be guaranteed. The cable adopts 3X7 galvanized / right-handed structure with high strength and good corrosion resistance. The cable guardrail is composed of an end column, an intermediate end column, an intermediate column, a bracket, a cable anchor, and a fastener. The quality of cable guardrail should be examined in terms of corrosion resistance, material properties, geometric dimensions and appearance quality.

highway guardrail tools choose

Because the application field of road guardrail is very wide, we will use road guardrail in many times, so what should we pay attention to when choosing highway guardrail tools? Today HongDa introduce it. According to the introduction of road fence manufacturers, we need to pay attention when choosing highway guardrail tools:

1、The quality of the highway guardrail tools and frame of the road guardrail, the highway guardrail tools and frame of the guardrail is also a place which is lower than that of the angle steel and the round steel, but the angle steel and the round steel in different parts should be different.

2、In general, it is necessary to pay attention to the uniformity of the sprayed plastic, and the quality of the coating is also essential. Again, it is the management of the spray technology and the advanced degree of the equipment.

3、The quality of highway guardrail tools is made by welding of different sizes of wire rod (Tie Si). The diameter and strength of the wire rod directly affect the quality of the mesh. In the field selection, we should choose the finished product Tie Si produced by the regular manufacturer; the next is the welding of the mesh or the preparation process. This is mainly the view of the technology. The skilled and operational skills between the operator and the good production machinery are usually well connected with each welding or fabrication point. Some of the regular guardrails produced by Anping are produced by automatic welding machines, while manual welding is used in a small factory, and the quality is usually very difficult to ensure.
