INTRODUCTION:
Xinyi City rents 18-meter bridge inspection vehicle, bridge guardrail installation vehicle, Xinyue Road Bridge toll-free hotline 135-0000-3760, Ms. Fang, WeChat mobile phone with the same number, online all the year round. Damage analysis: First of all, the structure itself (design reason), the principle of this kind of expansion device is to meet the expansion and contraction of the beam by the shearing deformation of rubber between the upper and lower grooves. Steel plates are embedded in the telescopic body, bearing load across the gap of the beam end, and anchoring steel plates are arranged on both sides, which are connected with the beam end by bolts and installed in blocks per meter, so the integrity is poor. Because of the large horizontal friction of this type of telescopic device, the requirements for the anchoring system are extremely high. Secondly, the product quality is not good, for example, the material performance of rubber, the material and reasonable arrangement of stiffening steel plate, the bonding strength between steel plate and rubber, the control of temperature and humidity during production and so on are all very strict, and there are some quality problems, such as whole plate breakage, degumming, adhesive layer wear, steel plate exposure, anchor bolt shearing rubber plate flying out and so on, which are directly related to the quality of rubber expansion device itself, large lateral width and large stiffness difference. Xinyi City rents 18-meter bridge inspection vehicle, bridge guardrail installation vehicle, and rents Xinyue Road Bridge free consultation hotline 135-0000-3760, Ms. Fang, WeChat hand.
