ECS deck continuous device end waterproofing

In order to prevent the water in the rubber seal tape from flowing toward the abutment, the splay heads can be installed at both ends of the ECS deck continuous device. The swell of the ECS deck continuous device can be different according to different road designs (warp length and angle). The squat is usually placed inside the collision wall.

The main reasons that affect the damage of ECS deck continuous devices

The ECS deck continuous device is exposed to the repeated action of vehicle loads due to the weak position of the beam end structure, and is exposed to nature, and is affected by various natural factors. Therefore, the telescopic device is easily damaged and difficult to repair. Parts. There are many reasons for the damage of the telescopic device. 1785855258 pay

The main reasons are:

1, poor design

The end of the beam was not carefully considered when designing. Under repeated loading, failure of the beam end caused the failure of the telescopic device. In addition, sometimes the amount of deformation is not calculated properly, and an excessive expansion distance is used, causing the expansion and contraction device to break.

2, ECS bridge continuous device itself

The structural rigidity of the telescopic device itself is insufficient. The strength of the anchored component is insufficient, resulting in varying degrees of damage during operation.

3. The improper selection of the post-casting and filling materials for the ECS deck continuous device.

The post-press filler material of the telescopic device was not seriously treated and carefully selected, resulting in a decline in the operational quality of the telescopic device and resulting in varying degrees of disease.

4, improper construction

During the construction process, the distance between the continuous devices of the beam end ECS bridge deck was not completed according to the design requirements, and it was artificially enlarged and reduced. The position of the positioning angle steel was incorrect, and the telescopic device could not work normally. This will result in the following conditions: due to too small a gap, the rubber expansion joint will produce a bump due to the over-extrusion of the protrusion; because of the excessive sewing distance, the shear force under the load and the inertia of the vehicle will loosen. The expansion joint rubber brings out the positioning angle, creating another type of jump. When the construction of the retractable device anchor steel welding is not solid enough, or the phenomenon of missing embedded anchor steel bar, causing hidden dangers to the expansion joint itself; construction of the installation of the retractable device is not good, after the bridge deck pavement expansion joints pouring is not good, During use, the expansion joints are damaged due to repeated loads.

5, ECS deck continuous device settings are not perfect

In order to reduce expansion joints, a large number of continuous beams or continuous decks are now used. Continuous seams need to be set up on the bridge deck. Currently, the continuous seams are not well-prepared, resulting in continuous seam damage and bridge jumping. The width and depth of the deformed false seams are not standardized enough and are not uniform in the continuous seams of the bridge deck, which also affects the normal work of the continuous seams to varying degrees.
