Bridge usage & maintenance


Following maintenance measures shall be adopted while using the bridge.


(I) Signs on bridgehead Traffic signs shall be set on both bridgeheads, showing load level, speed

limit, etc., with strict precaution against overload. If necessary, adopt compelling measures for load

and speed limit.


(II) Regular inspection and maintenance, which shall include


1. Check regularly various pins, bolts, beam clamps and sway braces, so as to maintain in a proper

status.


2. Check regularly whether there is any uneven sedimentation to the bed plate of girder and block of

bridge approach, and deal with any problems immediately.


3. Smear grease around the pin for preventing rainwater from entering the aperture of pinhole. Smear

grease around the outer part of bolt for preventing against rust.


4. Measure regularly the midspan deflection for finding whether there is gradual enhancement. The

speed of deflection enhancement shall be in direct proportion with the wearing degree of pin

and pinhole, and the enhancing degree shall be very small. If the speed of deflection enhancement

is too fast, it shows that there’s damage to pin, pinhole, upper or lower truss chord member

(including reinforced chord member), therefore, detailed inspection shall be made for adopting

measurement.


5. Check regularly whether there is any crack to the male end of lower truss chord member. If there

is any, measure the length of crack, and take monitoring measurements for preventing the truss

from damaging, and replace the truss in time.


6. Check regularly whether there is any fracture, curve or unevenness to bridge plate. Replace the

damaged immediately. If there is frequent pass of creeper truck on the bridge, track plate should

be paved for avoiding fast abrasion.


7. Bridge components or accessories, except the touching parts, have painted two coats of paint.

For long usage and protecting the steel material, the best thing would be to paint all one coat

after erecting the bridge. Some components need pre-paint before erection.


8. Clean the bridge deck regularly.
