Suspension bridge as a kind of auxiliary transportation amusement facilities, because of its beautiful shape, extensive participation, transcendent experience, more and more by the majority of investors Qin favor. Suspension bridge, also known as suspension bridge, consists of suspension cables, towers, booms, anchor spindles, stiffened beams and bridge deck system. It is a bridge with tension suspension cables as the main load-bearing member. Because the suspension cable is subjected to tension, no bending and fatigue caused by stress reduction, can be made of high-strength steel wires, so the suspension bridge spanning capacity is the bridge system in the zui big. According to the size of the stiffness of the bridge deck system, suspension bridge can be divided into flexible suspension bridge and rigid suspension bridge. Flexible suspension bridge deck system generally does not have stiffening beams, so the stiffness is small, under the action of vehicle loads, the bridge deck will change with the shape of the suspension cable and produce S-shaped deformation, unfavorable to traffic, but it is simple construction, generally used as a temporary bridge. The deck of rigid suspension bridge is strengthened by stiffened beams with greater stiffness. Stiffened beams can withstand vertical loads with the overall structure of the bridge. In addition to the above forms, in order to enhance the stiffness of the suspension bridge, can also be used in the form of double chain suspension bridge and inclined boom suspension bridge, but the structure is more complex.
Daily routine inspection, mainly bridge deck planks firmly, there is no obvious cracking, handrail whether there is a loose place, etc., a month should carefully check the main load-bearing structure, such as the foundation whether there is shifting, loose, etc., whether the wire rope is intact, whether the wire rope anchors are worn out, whether the bridge is tilted, the bridge body sagging amplitude, the wind cable is firm, the wind cable foundation is loose, etc.. This is our public service in accordance with the relevant provisions of the state to the scenic area to develop the daily workflow: opening time, the bridge should be directed by staff at both ends, to prevent too many tourists on the bridge, such as tourists focused on the phenomenon of crowding, should be timely channeled away to stop tourists deliberately swaying to stop tourists jumping, rolling, etc., to prohibit tourists from climbing, stepping on the guardrail, after the closure of the park to clean up the bridge surface, daily inspection, such as the discovery of routine problems, according to the equipment safety use, maintenance manual to solve the problem If you find routine problems, you can solve the problem according to the equipment safety use, maintenance manual, if you can not solve the problem, please contact my production unit in time.
