Kunming Lu advised that the model of the high-speed wave guardrail end was meticulously damaged. Technical innovation Kunming Lu advises the use of Q235 ordinary carbon structural steel as the steel material for wave guardrail panels, columns and anti-blocks and connecting bolts (referring to the connecting bolts between columns and guardrails). Manufacturing costs: industrial, agricultural, municipal, transportation Fences, decoration, protection and other facilities. Welcome to call Zhenjiang for galvanizing treatment: When serving sincerely on the guardrail, its rigidity and flexibility allow it to quickly absorb collision energy, thereby changing out of control. Kunming Lu advises the high-end waveform guardrail end model to work carefully with the waveform beam guardrail panels and columns. The steel used for the anti-blocking block and the connecting bolt (referring to the connecting bolt between the column and the guardrail) is Q235 ordinary carbon structural steel, and its technical conditions should conform to the provisions of the "Carbon Structure Drawing". The yield point of the steel should not be less than 235Mpa. The tensile strength should be in the range of 38 460Mpa. When the bending radius does not exceed 5 times, cracks do not occur. The resource-impregnated wave guardboard is a plastic coating process, which is to coat plastic on the substrate (usually metal), such as: our daily clothes drying racks, pliers handles, cut rubber covers, various Handrails, etc. According to whether heating is required, it can be divided into hot dip and cold dip. According to the raw materials of dip, it can be divided into dip and powder dip. Expressway wave guardrail board dipped plastic is to heat the metal and spray plastic powder uniformly on the metal to form a plastic film, or heat the dipped plastic solution into metal parts to cool the plastic and cover the metal surface. This process is widely used because it does not require molds, has low processing costs, is easy to form, and can process a variety of shapes. High-speed guardrail slabs can be used to treat the surface in this way, but the cost is higher than plastic spraying and the effect is better. Others are more used for wire mesh products. Customer first
Kunming Lu advised that the high-end wave guardrail end models should be carefully made. Therefore, it is necessary to maintain a good mental state in the construction project of sprayed plastic guardrails so that the entire construction of the sprayed guardrails can be completed. Therefore, when choosing the season for the construction of guardrail panels, if it is not particularly urgent, the spring and autumn seasons must be selected. These two seasons are more conducive to the installation of sprayed guardrail panels and are suitable for the safe construction of sprayed guardrail panels. season. Because the role of the wave barrier is very huge, Runjin reminds everyone: every driver and master must protect public transportation facilities to ensure the safety of others, and at the same time ensure their own safety. Monitoring data show that on August 19, the Shanghai rebar inventory totaled 250,000 tons, a decrease of 650,000 tons from last weekend; wire rods of 50,000 tons, an increase of 0.2 million tons from last weekend; Reduced by 10,000 tons over the weekend. According to the relevant spot introduction, Kunming Lu advised high-speed wave guardrails, the total size of Shanghai's construction steel stocks was 37,000 tons, which was 550,000 tons less than last weekend. Last week, Shencheng continued to experience high temperatures, and the transaction remained sluggish. The monitored daily purchase data of the Shanghai snail terminal dropped by 63% month-on-month. However, due to environmental protection factors, steel mills in the surrounding Jiangsu region have limited production and reduced production, and the market inventory has continued to decline. Corrugated beam guardrails are classified according to the setting location and the collision level. According to the setting location, it can be divided into roadside fences and divider fences. It can be divided into B-level and B-level according to the collision prevention level. The guardrail is a reinforced type, which is suitable for use on particularly dangerous sections of the roadside, and Class B is used for special highways. Kunminglu advises greening and beautification is an important part of highway maintenance. It is an important factor to prevent soil erosion, stabilize roadbeds, reduce noise, protect the environment, and create a beautiful and comfortable driving environment. It is also a beautiful scenery of highways. According to the good needs of trees and the special requirements of road traffic, timely take technical measures such as watering, fertilization, plastic trimming, and pests and diseases to keep the green matter in a good growth state. Maintain green plants, remove debris, prevent damage caused by other reasons, make timely repairs to improve the survival rate and preservation rate of seedlings, and achieve their ecological functions and landscape effects. Inspection environment Road guardrail can be divided into a variety of anti-blocking blocks galvanized / plastic sprayed according to different materials. Click to view Yancheng can be divided into roadside fences and divider fences according to the setting location. Kunming Lu advises that the high-speed wave guardrail end model is meticulous in workmanship for the guardrail board. In general, the processing of the guardrail board has a good anti-blocking product property: hot-dip galvanized electrostatic spray anti-blocking block. Treatment, the inner coating is hot-dip galvanized, and the surface coating is made of full polyester powder coating, which is firmly combined with the substrate by electrostatic spraying. The anti-blocking block is a part of the highway wave guardrail used for the safety protection of the fence decoration in the transportation industry. Corrugated beam splicing phase inspection environment
Kunming Lu advises that the high-end wave-shaped guardrail end models are made of meticulous plastic spray products, which are mostly used indoors, and plastic-impregnated products are mostly used outdoors, which are more expensive than plastic sprays. The material has the characteristics of being softened by heat and being able to solidify and form a film after cooling. It is mainly a physical melt plasticizing film forming process. Inspection results The bridge structure anti-collision guardrail is an exposed project that is only visible during driving of the structure and affects the aesthetic appearance. The quality of the project and the accuracy of the geometric dimensions directly affect the overall image of the project, so the quality requirements are very high. high. How to ensure the geometric size and beautiful appearance of the anti-collision guardrail is the goal pursued by the construction unit. Due to the shape characteristics of the anti-collision guardrail, the construction technology is difficult to master. How to develop a course to do good road maintenance is an important topic that our maintenance staff must consider. Highway maintenance is divided into daily maintenance, regular maintenance, special maintenance, and improved maintenance according to the country. The daily maintenance of the work we are currently engaged in is frequent daily operations of highway components (including auxiliary facilities) as needed every year. The purpose is to keep the highway in good condition and level. The routine maintenance projects mainly include: cleaning of roads and other parts, repair of minor damage and replacement of facilities, mowing of grass and tree branches, snow removal in winter, deicing, and emergency interrupted traffic Handling. Guardrail guards are important. Some highways are closer to the village, and some can't go to the sides of the highway to steal guardrail guards. As a result, there is a large amount of rainwater in the column of the guardrail board. The rainwater is corrosive to varying degrees, and the protection effect of the column is seriously affected for a long time. Since the guardrail board is a protective facility applied on the highway, Kunming Lu advises the installation standard of high-speed wave guardrails. It receives wind and sun all year round. Kunming Lu advises the installation height of high-speed wave guardrails. Dip coating or spray coating of steel plates; I believe everyone has heard of it. How to explain the fence plate? Here ’s what it means: In short, it ’s a protective facility made for the safety of the vehicle while it ’s driving; it ’s the deformation of the pillars to absorb the collision energy, and force the out of control vehicle to change direction, return to the normal driving direction, and prevent the vehicle from crashing. Out of the way to protect vehicles and passengers and reduce losses.
