1, the pre buried steel beam plate if the position is wrong or leakage is pre buried, is the anchorage method to reinforced fill. |
2, after cutting to clean up the link anchor. |
3, steel welding seam welding should be enough, to firmly. |
4, the elevation of the surface of concrete to prevent the right, jump out of the vehicle. |
5, the expansion joint anchorage firm, not loose, flexible and effective. |
6, the curing time of concrete should be enough, not because of lack of maintenance time open to traffic. |
1, the design of the bridge expansion joint is not a week. |
2, the problems of expansion joint device |
3, after the pouring of expansion device of pressure filling material selection |
4, the construction is not reasonable |
5, continuous joint setting is not perfect |
1, due to transportation expansion device length limit, can block manufacturing, field stitching. Expansion device stored in the site should be placed in parallel, not cross stacking, to prevent deformation. |
2, the factory, connecting fixture only as transport convenience, the gap is not fixed position. Expansion device installation, should be recognized under the supervision engineer. Can have provisions such as design documents, the provisions of the bridge design documents as the basis. |
3, a retracting device of hoisting, will be reserved for concrete groove hair and clean. When installing expansion device along the bridge to the width of a value to deal with that on expansion joint gap, and the top surface elevation and elevation design of anastomosis after pad, then wear a balance to the connection level reinforced, telescopic device on the anchor bars and beam embedded bars on both sides of the welded (as far as possible to increase the length of welding and welding point, to extend the service life of the telescopic device), to relax the fixture, the free expansion. At this time stretching device has entered the working state. |
4, to complete the process, install the necessary template, in order to prevent the inflow of mortar joints, and then carefully washed. In the concrete pouring preformed groove is larger than that of C50. The concrete pouring concrete should take necessary measures to vibration compacting. |
5, after the initial setting of concrete, pull out the template, timely removal of the foreign body in the expansion joint and special shaped steel. |
