Problems solved by technology

[0002] With the continuous improvement of living standards, bridge vehicles have entered thousands of households. In order to alleviate the traffic pressure, the bridges that have been built are facing the need of widening. The connection between the widened beams is corroded, resulting in unstable connection, poor integrity of the widened beam body, and reduced service life of the widened bridge. Therefore, we propose a waterproof splicing for municipal bridge widening structure

Embodiment

[0028] 1) Splicing and splicing preparation: first form the independent support block 4 and the T-shaped support bridge 6, then fix the joist 8 on the pier and the widened beam body 5 by screws or by pouring, and install the independent support block 4 On the left and right groups of joists 8, install the road surface waterproof assembly 13 and the widened road surface 12 in sequence, then insert the positioning rod 11 into the through hole reserved on the road surface waterproof assembly 13 and the widened road surface 12, and finally screw in the bolt 10 Fix the fixing plate 9 on the right side of the widening beam body 5 to complete the widening operation of the bridge deck 1. In order to strengthen the support, a transverse reinforcement component 7 can be installed on the T-shaped support bridge 6;

[0029] 2) Construction of transverse reinforcement components: Insert the roofless reinforcement box 71 into the grouting groove 74 from front to back, and then the sealing pl...

Abstract

The invention discloses a waterproof splicing structure for municipal bridge widening, and belongs to the technical field of bridges. The structure comprises a bridge deck, the right end of an inserting block is connected with an independent supporting block, the right end of the independent supporting block is connected with a widening beam body, and the right side of the top of the independent supporting block is provided with a widening road surface; a road surface waterproof assembly is arranged between the widened road surface and the bridge floor, firstly, independent supporting blocks and a T-shaped supporting bridge are formed, then the joists are fixed to the bridge piers and the widened beam body through screws or in a pouring mode, and the road surface waterproof assembly and the widened road surface are sequentially installed. In order the reinforce the support, a transverse reinforcing assembly can be additionally arranged on the T-shaped supporting bridge, the topless reinforcing box is inserted into the grouting groove from front to back, concrete is injected into the topless reinforcing box at the moment, the concrete enters the grouting groove and the grouting groove through the grouting holes, and after the concrete is solidified, the supporting effect of the topless reinforcing box can be improved through the concrete reinforcing layer; the special-shaped concrete reinforcing layer can grasp the widened beam body and the T-shaped supporting bridge.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a waterproof splicing structure for municipal bridge widening. Background technique [0002] With the continuous improvement of living standards, bridge vehicles have entered thousands of households. In order to alleviate the traffic pressure, the bridges that have been built are facing the need of widening. The connection between the widened beams is corroded, resulting in unstable connection, poor integrity of the widened beam body, and reduced service life of the widened bridge. Therefore, we propose a waterproof splicing for municipal bridge widening structure. Contents of the invention [0003] The object of the present invention is to provide a waterproof splicing structure for widening municipal bridges, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the foll...
