. When users install modular bridge expansion joints, once collision and deformation occur, it is difficult to repair
It is a qualified product, so during the entire installation process Measures must be taken to protect and no vehicles are allowed to pass through.
The construction unit must carefully operate the product. If it is difficult to adjust on site, the finished product of the expansion joint must be carefully and carefully inspected. Unqualified Transported to the site.
Before installation of modular bridge expansion joints, the position and size must be checked with the design drawing and on-site
and then placed firmly into the reserved slot.
. The gaps at the joints on the bridge must be sealed with polyethylene foam boards to prevent concrete from being poured in when pouring the protective tape, which will cause the joints to fail. At the same time, concrete must not be poured into the device to avoid changing the image. The tape is blocked.
.After the installation of the complete modular bridge telescopic device protective tape and the concrete pouring, it must
be timely sprinkled and cured the day before to facilitate the increase in strength and prevent the occurrence of cracks.
< r (>Model-type bridge expansion joint installation methods and technical measures:
First, we use fences to enclose each expansion joint of the bridge. The fences should be reinforced to ensure that they are firm. And assign a special person to guard it, and any unrelated personnel are strictly prohibited from entering. In order to ensure the quality of the expansion joint, the construction of the expansion joint is carried out by a professional construction team and experienced operators. First, release the center line of the expansion joint, and then draw the edge line of the expansion joint groove. Finished After the line, lay colored strips of cloth along both sides of the line, and use sealing tape to fix the strips of cloth along the marked line to prevent contamination of the oil surface. Use an asphalt concrete cutting machine to cut the paved road surface.
The seams should be aligned with the pavement joints on both sides. The depth of the seams should be Clean the sand and gravel, remove the wooden boards, and remove other debris with water. After removal, move the colored strips down accordingly to strengthen protection and prevent damage to the corners of the expansion joints. After cleaning the expansion joint groove (including debris around the support), fill the expansion joint with foam board. The foam board must be filled tightly. If the oil surface on both sides of the groove is uneven, the width of the groove should be widened to cut off the uneven oil surface. Make sure the groove is at least as deep as possible after removal. Then use a wrench to adjust the previously laid-down embedded steel bars to the appropriate position. After completion, ask the supervision engineer for acceptance. After that, check the quality of the expansion joint, and install it in the groove after passing the inspection.
