<p> Zunyi Chishui Sprayed Plastic Guardrail Board Price Related Contents When you need a guardrail board, you need to determine what protection level you need. The anti-collision level of the galvanized wave guardrail required by different sections is different. Or directly tell the manufacturer where to install it, such as: village road middle zone, highway isolation zone, two sides of highway, etc. Good guardrail board manufacturers will give clear wave guardrail models so that you can choose a more suitable guardrail board. . Inspection conclusion The installation of the guardrail panel of Zunyi Chishui corrugated board must be performed after the strength of the concrete of the column has reached a certain level. Good steps for equipment management: Safety students take good steps in front of the guardrail panel repaired by the security personnel of the maintenance institute: good and teaching work, the advantages of Zunyi Chishui sprayed plastic guardrail panels, whether the dressing of maintenance personnel meets the requirements, road repair vehicles and pallet signal signs Is it normal? Honestly serve the height of the Benxi pillar: Whether the top surface of the pillar is smooth or not determines the smoothness of the top surface of the guardrail board. The height of the pillar is a major factor affecting the alignment of the anti-collision guardrail. In the initial construction of the anti-collision guardrail, we all assumed that the curb stone was absolutely at the design level. According to the construction drawing, the top surface of the column was elevated 70 cm above the curb stone. When driving into the column, when it reached the top of the column to the curb stone top When the surface is 70cm, record the position of the pile hammer on the pile driver's guide post. For each subsequent post, when the pile hammer drops to the recorded position, it means that the post is in place. In this way, the irregularity of the curb stone top surface is reflected on the top surface of the pillar, which eventually makes the guardrail panel as a whole uneven. Due to the time and cost of the high and low school, it is difficult and difficult. The pavement design elevation calculates the design elevation of the curb stone top surface, and then calculates the elevation of the column top surface according to the top surface of the column should be 70cm higher than the curb stone top surface, and then measures each of the columns when it is driven into the column. However, although this ensures the smoothness of the top surface of the column, due to the error between the actual elevation of the pavement and the design level, and the error is large, there will be a phenomenon that the height of the column from the top of the curb is not the same. We are on the Zhengzhou to Xinzheng Expressway During the construction, there are sections where the line is laid like this. Some of the top surfaces of the pillars are more than 70cm away from the top surface of the edge stone, and some are less than 70cm, which also affects the appearance and is more complicated. During the discount period, the wholesale price of Zunyi Chishui sprayed plastic guardrails, the horizontal combination of the beams absorbed energy and the vehicles deviated. Zunyi Chishui Sprayed Plastic Guardrail Price Related Contents The above are the several surface treatments commonly used in the daily use of highway wave guardrails. The purpose is to prevent rust and oxidation, to beautify the environment, and to do the best without affecting the physical properties of the material. It is possible to increase the natural life of the guardrail material. Consumption wave beam steel guardrail is a semi-rigid guardrail with fixed rigidity and flexibility. It is a beam-type structure fixed by pillars. The anti-collision performance of the corrugated beam guardrail is the friction between the vehicle and the guardrail, the friction between the vehicle and the ground, and the vehicle and the guardrail itself generate a certain plastic deformation to absorb the collision energy, extend the action time of the collision process, reduce the speed to ensure personnel safety and reduce the vehicle damage.

</ p> <p> The price of Zunyi Chishui sprayed plastic guardrail is related to the setting of the corrugated beam steel guardrail. According to different road conditions and installation locations, its anti-collision performance requirements are different. The guardrails installed on the highway subgrade are divided into two levels of S and t, which are divided by the level of collision prevention. The barrier levels are Am and Sm. Guardrail panels and cable guardrails are highway protection products. Both functions are basically similar in terms of function and protection, but they also have their own disadvantages and advantages. There is no single protection on the expressway. A combination of the two is required to better protect the smooth flow of the expressway and the safety of the expressway. Anti-collision barriers, as basic safety facilities on highways, play an important role in promoting traffic safety on our high-grade highways. After loading the guardrail board, we can calculate the length that the guardrail board can be laid according to the weight of the guardrail board on the car. It can be divided into S-level and S-level according to the collision prevention level. The S-type guardrail is a reinforced type, which is suitable for particularly dangerous sections on both sides of the road, and is used for special highways. Zunyi Chishui Pillar can only be installed after the foundation strength of the concrete reaches 75% of the design. Where does cold spray zinc cathodic protection work? Unlike cold paint, its dry film contains more than 96% pure zinc, which can provide good cathodic protection for steel. Long-term protection of steel surfaces, even in harsh environments. Performance can be comparable to or even better than hot-dip galvanizing. Barrier protection effect When the cold spray zinc coating is oxidized, a zinc salt layer will be formed on the surface of the coating for barrier protection. At the same time, the adhesive in the cold spray zinc coating also provides additional barrier protection, thereby slowing the oxidation of zinc. Therefore, the corrosion performance of cold spray zinc coating is better than zinc spray (aluminum), hot-dip galvanizing and other zinc-rich coatings. The most common methods of guardrail board column equipment include mechanical piling method, drilling method and pouring and mixing after excavation. Affordable Hainan, after the stakes are staked out, the surface condition of each pillar position should be adjusted. In the case of communication pipelines, water leaks, etc., or when the depth of the top of the culvert is insufficient, the position of some pillars should be adjusted to change the pillar fixing method. Zunyi Chishui Sprayed Plastic Guardrail Board Price Related Contents Highway wave guardrails Highway collapse levels can be divided into A-level and S-level. S-level guardrails belong to the grade-level private roads that enhance the use of roadsides at particularly risky sections. The common bumping level of a roadside beam guardrail can be divided by B, A, or human SSS. where is it? According to the load-displacement curve, the displacement is about 5cm, which belongs to the stage where the foundation reaction force is acting. The displacement is 5 ~ 50cm, which is exactly the bending stage of the column. The curve is gentle and the displacement increases quickly. The column of the guardrail board must not show signs of twisting, nor must it be welded at the interface or at both ends of the guardrail board to make it longer, especially the debris at both ends must be cleaned and tidy. In the initial design, the point of the highway should be used as the starting point. The distance between the columns can be adjusted according to the specific conditions of the distance. The installation details of the columns must be in accordance with the original design drawings and the road route Coordinating with each other, the pillars must be buried very firmly, and the depth of the embedding must be based on the initial design depth reference and perpendicular to the horizon.

</ p> <p> Zunyi Chishui Sprayed Plastic Guardrail Price Related Contents The wave guardrail is a combination of corrugated plate steel guardrails set on the waterfront and cliff sections of the highway. When a vehicle collides with it, the corrugated steel guardrail board has good resistance The impact performance and the energy absorption effect are not easy to be crashed, and at the same time, it can protect the vehicle and the passengers well. In order to ensure the safety of road traffic, Fuqing has added wave-shaped guardrails to the waterfront and cliff sections, bridges, and culverts as needed. The safety and sanitary corrugated beam steel guardrail is a semi-rigid guardrail with fixed rigidity and flexibility. The installation method of Zunyi Chishui sprayed plastic guardrail board is a beam-type structure fixed by pillars. The anti-collision performance of the corrugated beam guardrail is the friction between the vehicle and the guardrail, the friction between the vehicle and the ground, and the vehicle and the guardrail itself generate a certain plastic deformation to absorb the collision energy, extend the action time of the collision process, reduce the speed to ensure personnel safety and reduce the vehicle damage. The supplied wave guardrail panels are spliced to each other by splicing bolts, and fixed to the anti-blocking block (perhaps the transverse beam, bracket, etc.) by the connecting bolts. The overlapping direction of the subgrade guardrail and the wave guardrail board is the key to the equipment, and the equipment is carried out according to the drawings. The overlapping direction should be the same as the driving direction. The wave guardboard should be continuously adjusted during the equipment process. Therefore, the coupling bolts and splicing bolts should not be tightened prematurely, so that the long round holes of the corrugated beam can be adjusted in time in the process of the equipment to make it a smooth line shape and avoid some unevenness. When the linearity of the guardrail is considered satisfactory, tighten the bolts after all. Cathodic protection of cold sprayed zinc Cold sprayed zinc is different from ordinary coatings. Its dry film contains more than 96% pure zinc, which can provide good cathodic protection for steel. Long-term protection of steel surfaces, even in harsh environments. Performance can be comparable to or even better than hot-dip galvanizing. Barrier protection effect When the cold spray zinc coating is oxidized, a zinc salt layer will be formed on the surface of the coating for barrier protection. At the same time, the adhesive in the cold spray zinc coating also provides additional barrier protection, thereby slowing the oxidation of zinc. Therefore, the corrosion performance of cold spray zinc coating is better than zinc spray (aluminum), hot-dip galvanizing and other zinc-rich coatings. Problems to be paid attention to during construction The data of various facilities should be accurately grasped during the construction of the guardrail, especially the exact positions of various pipelines buried in the subgrade. Nothing should be caused to the facility during the construction process. In case of insufficient communication pipeline, drain pipe or culvert soil depth, the position of the column should be adjusted, or the fixing method of the column should be changed. Ranking combined corrugated beam guardrails are composed of columns, cross beams, corrugated beams, and fasteners. The columns can be round or channel-shaped steel. The cross beam is composed of two channel steels, which are installed on both sides of the column. The two ends of the beam are respectively connected to the corrugated beam plate. The large combined width of the corrugated beams on both sides is 100cm, which can also be adjusted appropriately according to the width of the partition. The identification and pricing of these two structures are both part and corresponding the difference. </ p>
