The width and elevation of joints between beam segments should be adjusted along the bridge by telescopic devices.

During installation, the width a of the expansion device along the direction of the bridge should be symmetrically placed on the gap of the expansion joint, and the elevation of the top surface should be consistent with the design elevation, then the horizontal steel bar should be penetrated, and both sides of the anchoring steel bar on the expansion device and the embedded steel bar on the beam should be welded firmly.

Matters needing attention in beam construction:

According to the field investigation, a well with a depth of 60m and a diameter of φ50cm is drilled at the edge of subgrade to ensure the production and living water. A 4*5*2m reservoir is set at the site, pumped to the reservoir by a water pump, and then maintained by the reservoir through an intelligent spray maintenance system, and then flows into the sedimentation tank through the drainage ditch of the beam field and discharged to the reservoir to form a circulation system, which can ensure the construction water.
