Hunan highway guardrail installation waveform guardrail installation company

①, when the wave beam installation, splicing each other by stitching bolt by bolt mounting to the post or crossbar. Mosaic wave beam direction is critical installations to ensure the overlapping direction should be consistent with the directions of traffic during construction. ②, wave beam during the installation process should continue to be adjusted, thus connecting bolts and splice bolt tightening is premature to use during the installation process a long hole wave beam of time to adjust, to form a smooth linear, avoid local unevenness. ③, when installing wave beam should be coordinated with the top surface of the road vertical curve. And check the fence linear, when determining linear smooth and relatively straight and smooth, the only final tightening bolts. 5 Note ① construction should be fully prepared, road construction Stake find exact position. Stakeout should precise error is within a predetermined range. ② column construction should be scrupulous, its verticality, spacing, bolt hole locations and other dimensions shall comply with the requirements, do not meet the requirements for immediate rework, while reworked should be strictly in accordance with norms JTJ074-94 regulations. Packaging and identification ③ waveform slab, columns and other components shall comply with the provisions of GB6725. When the fence can not purchase in bulk, and should ensure that the lifting, transportation, stacking process does not result in deformation of the product, damage (injury). Reliable transport process should be fixed, to prevent damage to the finish or cause bumps collision member deformed. ④ Note waveform Lianggao Jiang splice junction bolt packaging and labeling should be consistent with the relevant provisions of GB / T1231 when purchases. ⑤ fence construction when the operation should be cautious, not undermine buried under the pavement cables, pipelines and other facilities. Waveform guardrail highway guardrail manufacturer is the most important transportation infrastructure, our highways are developed from the 1980s, its national economy and social development plays an important influence. Important highway maintenance and security facilities. Highway guardrail is a typical cold-formed steel products, the specification is 4320 * 310 * 3 The company introduced the United States adopted the strip mill R425 automatic leveling, precision feeding punching, 18 rolls slowly forming, computer cut-off and other advanced process conditions, the maximum guarantee the geometric dimensions and linearity guardrail plate. Its cross-sectional dimension in full compliance YB4081-92 standards. Uses: Widely used in highways. Material: Stainless steel guardrail technical field of high intensity: The utility model fence panels, mainly used for road lanes split protection. Background: the current highway guardrail typically galvanized steel, resulting problems include: 1, leaf rust easily oxidized, 2, easily scratched car, 3, the production cost is relatively high, 4, less impact likely to cause deformation of the guardrail, 5, production process prone to contamination. The utility model technical problem to be solved is to overcome the deficiencies in the prior art exists, and to provide a good impact resistance, low cost, long life, high security, environmental protection, highway guardrail good effect board. The utility model fence solve the technical problems the technology used in the program are: the guardrail plate wherein the plate body is made of high molecular weight PVC material, without preservative, such as spraying process in production, truly green, and because the PVC material costs much lower than steel, lower its overall cost; the guardrail was M-shaped mechanical structure, a reinforcing plate hole exhibition along a direction parallel to the plate body, strengthen the wells coated with hot-melt glass fiber as a reinforcing rib, at the same time In the upper plate to strengthen the impact strength, the protrusions provided with two rows of holes and strengthening ribs. A, PVC highway guardrail new compared with the prior art, have good impact resistance, low cost, long life, high security, environmental protection, etc. 310MM width tailgate thickness: 3MM, 4MM. 1 t guardrail may be paved: 80 meters thick 3MM, 4MM 61 m thick. 3MM per kilometer thick heavy 12.3 tons, 4MM thick heavy 16.388 tons. Second, the column: roughness specification Q114, Q140MM length with generally 1.85 m, 1.95 m, 2 m, 2.15 m, 2.27 Mi Bi thick 4.5MM. Third, each with a 250 kilometer fence panels. Column spacing of 4 meters per kilometer by 250 columns, ends 2, column caps 250, 250 sets of screws, brackets 250, discourage block 250.
