Bridge expansion joint repair a construction plan, the construction is completed delivery of the process, due to a variety of factors that make a small amount of damage to the bridge deck and bridge slab partial transverse cracks appeared Second, the construction process of the second order, a deck panel repair program, traffic control because of the bridge has been put into use, so the construction of a certain degree of difficulty. According to the actual situation, in order to ensure the passage of vehicles, in the construction process only by adopting the principle of single opening single construction; construction area and the area of ??the use of reflective traffic barrels and reflective tape clearly isolate, not foreign construction workers during the construction activity in the construction area. Construction point at a distance of 300 m, 250 m and 200 m were placed seats obvious warning signs and speed limit signs, hand in the construction of fixed point 200 meters away to warn command; all construction personnel outer wear reflective clothing when work is prohibited hee laugh slapstick, and out of the quarantine zone. Machinery and equipment parked orderly, neatly stacked materials, clearly marked, and to ensure that non-lane away. Ensure construction and traffic safety; arranged as shown in Figure 1. 2, due to the bridge deck refurbishment of reinforced concrete structures belong to the entire board, in order to ensure the passage of the vehicle at the time of the refurbishment using framing piece construction. ①. Amend parts of the first with a single cutter will destroy part of the deck panels vertical and horizontal cut along a straight line to ensure straight-degree sector, can not destroy the original steel cutting, and does not break other parts intact. If at the time of the original steel cutting caused damage and destruction should be replaced to ensure the integrity of the structure of the surface layer of steel. Get rid of the use of pneumatic or electric impact drill drilled, drilled in addition to the original position of the grassroots; when not playing chisel construction on damage to the grass-roots structure; after chiseled artificial excavation. Construction waste disposal unified carried away when not invade the lane placement. Due to get rid of the construction process to keep the original steel structure, partial rupture and damage at the use of welding methods lap full complement. Clean-up drilling site, and rinse with water. ②. When pouring concrete pouring, waterproof adhesive can be used to cast parts of paintbrushes, the direct use of concrete ready-mixed concrete, concrete tanker arrived with a trolley of luck to cast parts. After the concrete into the drilling site by hand with a shovel will pave concrete spread, first insert tamping concrete vibrators, then flatbed concrete vibrators vibration compacting the concrete and vibration level. Then roll and artificial clappers will smooth concrete surface pressure light, until the concrete has some time before the concrete along the lines of the original embossed to form a standard concrete pavement. ③. After pouring the concrete curing molding to strengthen conservation, sent sprinkler and water conservation wet burlap cover. Conservation of 28 days to clear the road, and construction another one. ④ The construction process using assembly-line construction, the construction order: left front left lane - the right and the left hand lane - After the left lane on the left - the left front and right line - the line on the left and right rear - front right side of the left lane - Right before the line to the right - the right and the right line. The order both to ensure the continuity of the construction but also ensures that the concrete curing time. All use of reinforced concrete are first quality inspection, and physical properties of steel tested before use. Each step of the construction process, quality inspection personnel have accepted and be carried out under the supervision of a process by consent. Concrete pouring process have quality control inspectors and supervision present.
