Not to hurt the highway pavement concrete slab rapid removal equipment

Not to hurt the rapid removal of the deck slab concrete deck highway maintenance equipment to break construction technique concrete deck highway maintenance rid process, do the preliminary work, depending on the thickness of the concrete deck, steel the thickness and density of the steel mesh, etc., using a total of four bridge to get rid of the construction process, are outlined below, for comparison, learning and reference. First, do a good job security for high-speed bridge to get rid of security, there are four considerations: First place may appear in the bridge for pedestrians and vehicles (except channels) do a good job security side of the bridge and the bridge, the main is the use of safety net, or a double safety net or safety net plus color of the cloth. The second is for more intensive pedestrian traffic interchange and access roads at, to make a rigid protection, mainly bracket. The third is to bridge the gap filling (including port side joints, drain holes, etc.). Fourth, in the construction of the bridge should have a bridge security officer responsible for security field. Second, find the interface to determine the construction process of high-speed bridge pavement layer thickness difference between the larger, multiple construction points to use handheld before construction picks dug out a 30-50cm groove, find bridge deck plate, cross beams interface, and then determine local regions except cutting depth according to the thickness of the interface. Third, get rid of the bridge construction technology force Thatta crusher to break law 5cm thicker than plain concrete deck, first use of air gun drilling (hole depth attention to a uniform thickness and concrete), drill spacing of 30cm * 40 ~ 50cm ( * Column row spacing distance); and hydraulic crusher into 30cm * 40 ~ 50cm chunk; and finally labor, crowbar move. Also be sure to clean up when you pay attention to slag clean, close to the barrier wall to tank to crack and pops, excluded from the hole and the column down to 20cm. For thicker than 10cm of reinforced concrete bridge network, we can use the crusher to break laws, but to narrow the distance between holes is 20cm * 20cm, slightly tilted to the free surface while drilling, while finding reinforced the free end of the head, according to the tip Reinforced flexibility to determine the location of the cloth hole, slag picks assistance will also be required.
