Embodiment 1

[0014] The continuous processing method of T-beam bridge deck comprises the following steps:

[0015] a. Clean up the micro seams on the damaged bridge deck, remove the surface material, and expose the fresh concrete surface;

[0016] b. Re-set the connecting steel bar according to the original steel bar label in a conventional method;

[0017] c. Set the lining plate under the T-beam wing plate, and set the channel steel hanging beam on the top of the T beam. The channel steel hanging beam and the lining plate are fixed by connecting bolts. The channel steel hanging beam is embedded in the T beam and can be stretched forward and backward. , the connecting bolts are set in the channel steel channel;

[0018] d. Brush hot asphalt on the concrete surface, pour asphalt mortar and tamp it while it is hot, so that the treated part is flush with the original bridge deck.

Embodiment 2

[0020] The continuous processing method of T-beam bridge deck comprises the following steps:

[0021] a. Clean up the micro seams on the damaged bridge deck, remove the surface material, and expose the fresh concrete surface;

[0022] b. Re-set the connecting steel bar according to the original steel bar label in a conventional method;

[0023] c. Set the lining plate under the T-beam wing plate, and set the channel steel hanging beam on the top of the T beam. The channel steel hanging beam and the lining plate are fixed by connecting bolts. The channel steel hanging beam is embedded in the T beam and can be stretched forward and backward. , the connecting bolts are set in the channel steel channel;

[0024] d. Adhesive joint tape on the concrete surface, pour asphalt mastic and compact it, so that the treated part is flush with the original bridge deck.

Abstract

The invention disclose a T beam bridge deck continuous processing method, which belongs to the maintenance treatment field of bridge deck diseases. The method bonds hot bitumen or a joint adhesive tape and asphalt mastic to maintain and treat a wet joint of the bridge deck, the construction quality is excellent, the speed is rapid, and the effect is remarkable.

Description

technical field [0001] The invention relates to the field of bridge deck disease maintenance and treatment, in particular to a continuous treatment method for T-beam bridge decks. Background technique [0002] A large number of bridge deck disease investigations have found that after the wet joints between beams are damaged, the pavement surface of the bridge deck will show different degrees of network cracks, which will cause pits, transverse cracks and subsidence of the asphalt concrete surface. The processing method in the prior art is as follows: first, clean up the damaged bridge deck trace seams to expose the fresh concrete surface; then reset the connecting steel bars; finally set the lining plate under the T-beam wing plate, and pour C40 concrete again. However, after use, it is found that the effect of this emergency repair filling method is not obvious. Contents of the invention [0003] The technical task of the present invention is to provide a continuous trea...
