[Bridge expansion joints] transportation and installation of bridge expansion joints [] means of transport (1)] [bridge expansion joint devices are generally based on a group of four, when manufacturers supply has been fixed as well. Holistic telescopic device strapped to the flatbed, slow speed when cornering want to prevent overturning. (2)] [bridge expansion joint device shall be transported to classify each bridge bridge site, and a detailed check. [Installation] bridge expansion joints (1) kerf: Deck asphalt concrete paving is complete and the conservation of lancing after forming, before the beginning of the cut seam, which calls for asphalt pavement roughness testing, test results fulfill the requirements, it determined in accordance with the requirements of the construction drawings and accurately measure the width of the slot highway bridge expansion joints Recommended stakeout, and can pull two colored nylon rope as the kerf reference line, this will ensure accurate size slit, slit straight. (2) slotted: with picks slotting, grooving depth of not less than 12cm .. The first part of the asphalt pavement with two picks chisel cut sutural addition, bridge expansion joints [] after notching within notches to clear out all the debris, and the remaining residue with water cannons rinse. Cut sutures asphalt concrete pavement outside, in front slotted first color of the cloth or steel cover for protection, so that one can be slotted debris generated unity on top, on the other hand can be prevented when the slit powder contaminated surfaces. (3) Correction reinforced: Because when passing vehicles and paved road construction machinery and vehicles rolling, there will be some embedded steel deformed or broken welds should be corrected in accordance with the requirements of welding, to meet the embedded steel Dimensions requirements and installation of bridge expansion joints [requirements] means, at least to ensure that there are two on each side and embedded steel welding firm per 1m range. [Opinion] bridge expansion joints and bridge expansion joint damage repair [] means from the point of view of practice and relevant information, regardless of W, V-type, hollow rubber body type can be used. Colloid is not wrong in itself, but in the entire telescopic device structure design is reasonable. West Germany Maurer's telescopic device, in recent years, the application of more TST telescopic device design is reasonable, while driving it has a high stiffness, deformation of flexible time and temperature variations. From now the construction of a bridge expansion joints [] device, the flatness of the comb plate telescopic device is better, not only because adding a sufficient number of plates to increase the stiffness of the deformable body, but there are a sufficient number of rivets to make stretch coupling body with bridge expansion joints deformable body is strong, not like the original hollow rubber expansion joints as easily prolapse. And improved construction techniques, can play a waterproof, dustproof effect. The disadvantage is deformed like inflexible. [Destruction] bridge expansion joints form by Hulunbeier six routes and 15 medium-sized bridge the technical condition of roads and bridges survey GB Modular expansion joints, reinforced concrete bridge expansion joints were found to have varying degrees of damage, breakage rate more than 40%. The main form of expansion joints are: zinc metal joints, steel expansion joints, rubber expansion joints. Failure phenomena manifested in joints throughout the fall class quality bridge expansion joints, bridge beams to cover up and down through lost convergence between the hole and the hole; steel welded joints open, the wheels grind into the seam, making joints squeezed Man, lost telescoping effect;] [bridge expansion joints on both sides of the deck coverings wheels crushed, broken concrete was squeeze into the seam, and some are dirt, debris blockage that would not achieve the telescopic effect; vehicle The ends of the beam impact action causes crushing, so that the width of the individual bridge expansion joint reaches 10 ~ 30 m.
