Problems solved by technology

However, since the bridge pier will undergo a large horizontal displacement when it is subjected to a horizontal thrust, the decorative blocks will often be more or less affected by the horizontal thrust on the pier, resulting in damage to the decorative blocks, which poses a safety hazard
[0005] At present, the conventional method is to cut horizontal seams on the formed decorative blocks to minimize the horizontal thrust on the pier received by the decorative blocks. However, the horizontal seams cut out by this construction method have shallow depth, difficult cutting, and seam formation The size and effect cannot be guaranteed, the construction safety risk is high, and the cost is high.
In addition, due to the shallow depth of the cut horizontal seam, the decorative block will still be pushed horizontally by the pier, causing the decorative block to be easily damaged, posing a safety hazard

Abstract

A flexible-pier horizontal separation seam construction method and a construction apparatus therefor. The flexible-pier horizontal separation seam construction apparatus (1) comprises a combined drawing plate. The combined drawing plate comprises s bottom drawing plate (2), a hard foam plate (3), edge sealing drawing plate (4), and a top drawing plate (5); the hard foam plate (3) is located above the bottom drawing plate (2) and adjacently connected to the bottom drawing plate (2); a first side surface (31) of the hard foam plate (3) is flushed with a second side surface (21) of the bottom drawing plate (2); the edge sealing drawing plate (4) is located above the bottom drawing plate (2) and adjacently connected to the bottom drawing plate (2); a third side surface (41) of the edge sealing drawing plate (4) is adjacently connected to a fourth side surface (32) of the hard foam plate (3); the fourth side surface (32) is provided opposite to the second side surface (21); the top drawing plate (5) is located above the hard foam plate (3) and the edge sealing drawing plate (4) and adjacently connected to the hard foam plate (3) and the edge sealing drawing plate (4) respectively; a fifth side surface (51) of the top drawing plate (5) is flush with the first side surface (31). Also provided is a construction method for the construction apparatus. The flexible-pier horizontal separation seam construction method and the construction apparatus therefor both have the advantages of high seaming depth, high seaming accuracy, and good seaming quality.

Description

Technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular, to a construction method and a construction device for the horizontal separation of flexible bridge piers. Background technique [0002] With the continuous development of our country’s economy, the requirements for the quality of urban bridge construction are getting higher and higher, and the requirements for the landscape of the bridge are also getting higher and higher, making the bridge a landscape of a city, or even a city’s landscape. business card. [0003] At present, most bridges are multi-span bridges. Generally, the two ends of multi-span bridges are equipped with abutments with greater rigidity, and the middle piers are all set as flexible piers, so that when the piers are subjected to the thrust of the pier top, A large horizontal displacement can occur within a safe range, and the horizontal connection between the piers of the bridge is completely i...
