Roads and bridges should be arranged within the support cushion stone steel mesh, bar diameter of not less than 8mm, spacing appropriate for the 50mm * 50mm, should be connected to the vertical steel reinforcement inside the piers, stone pad for pouring concrete strength not less than C40, at the same time, the top surface of the concrete pad stone should be pre-calibrated with a spirit level, and strive to smooth rather than smooth, clean surface and to ensure unidirectional sliding bearings, dry, sand and other fluorine-free. Highway bridge bearing pad stone top surface elevation should strive bearing pad stone top surface will be the same elevation level, this top must be strictly controlled. The same highway bridge support cushion stone height should be less than 0.5mm, its relative height should not exceed 1.5mm vertical sliding bearings, in order to avoid bias, the initial shear deformation and appear uneven force phenomenon. Roads and bridges now pouring into every branch of installation is relatively simple, highway bridge bearing construction sequence, cleaning and sorting support cushion stone, the first branch before receiving seat cushion top surface of the stone bridge pier or remove loose sand table keep the pad stone top surface clean and free of oil directional sliding bearings, if elevation deviation stone piers support cushion is too large, use a dry hard cement mortar to adjust. Ensure flatness and precision elevation pad stone. On the lower part of the construction design drawings, not only to the abutments, piers reserved hole itself, but also to draw a reference line around the bridge and use it to identify all the abutment pier on the baseline measurement, but also the upper structure construction should pay attention to issues such as long bridge, span long, diagonal size, highway bridge bearing centerline of the highway bridge bearing position, the direction of the highway bridge bearing installation, bearing underside design height and the top surface of the lower structure design height indicated on the design drawings. Construction should pay attention to the problem of holes for construction, bridge construction at the top and bottom for construction by different construction units, lower structure construction unit, we must fully consider the construction work of the next class of tectonic units set aside for construction of the hole. During the construction, highway bridge bearings seriously in accordance with design drawings confirm the location, height, size bearings, roads and bridges bearing anchor bolt aperture, depth and vertical degree, the general accuracy of reserve requirements for construction hole locations. Design height 10mm-30mm. Vertical plane position 20mm highway bridge bearing anchor bolts below.
