Twin block sleepers guard Baoding in Hebei mold factory is specialized in the production of railway sleepers shield manufacturers, the company focused on high guard rail pillow production, the company produced double-block sleepers guard, sleeper shield, heavy sleepers protective cover, SK-2, double-block sleepers guard, Subway sleepers shields, and other products for slab track and Borg-track sleepers, submerged rail sleepers, as long sleepers embedded sleeper, short embedded sleeper sleeper etc., can also be customized plug-processing, the company has many years of experience in the production of sleepers shield, I produced the sleeper foot guard afraid strong impact, etc., product quality assurance, price concessions, Welcome friends to inquire order. This product uses the methods and precautions Step 1: Before pouring clean up debris pouring surface, may not have water before pouring the filling layer invert wet after watering. To ensure fresh concrete sleeper with a combination of good, need to spray before pouring on the sleeper 1. Covering sleepers, fasteners and rail with protective cover. Check the adjustment screw each rail rafts whether vacant. Check the terminals are dense paste the template. Straight sections corresponding end position of each track on both sides of the deck (4 points), the curve corresponding to each channel bed board lots on both sides of the ends and the middle position (6 points) and the top surface elevation measured templates and design elevation (consider drainage slope) control technician Inverse position by pouring surface was technical director after review with double-sided adhesive tape on the side of the logo template, the top surface of the rail in the calculation for the design elevation, on the outside of the line low 15mm, relying on the line side High 5mm, inspector template based on the measured top surface elevation and the design elevation difference between the steel tape measure to check the correct position of double-sided adhesive, double-sided adhesive edge line of the top surface of the concrete pouring for the line of control; to both sides of the template Under the double-sided adhesive edge for the two end points, close to the pull side sleeper ink lines in the corresponding side sleeper elastic line, as the drainage slope control lines. Step 2: Check and confirm the track row retest results. Before pouring the concrete, orbital geometry of the review, exceeding the allowable deviation should be re-adjusted. Step 3: concrete mixing and transport. Road mattress centralized mixing concrete by mixing station, using concrete trucks pouring straight unloading way (single line during the construction) construction. After the use of concrete trucks concrete transported to the construction site, should be checked every vehicle of concrete slump, air content and temperature indicators before discharge after passing; Step 4: Concrete cloth. Using one end to the other end of the continuous, when the concrete sleepers from a sleeper automatic overflow to the next post, before moving to the next one before pouring sleeper continue to move forward. When unloading straight pouring concrete truck chute Go to the top of the rail to be pouring row (down spout about 20cm above the top rail, by adjusting the adjustable spout under the bottom of the concrete truck cranked device implementation, adjustable range of 80 ~ 160cm ), cutting open the valve. Cutting process must pay attention to timely vibrators, slowly cutting should be uniform, not the impact of rail and sleeper exhaust shield. Step 5: The product is optional ring use, special attention must be cleaned after each infusion guard above the debris and water slurry, to pave the way for the next use.
