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

The invention discloses a flexible-pier horizontal separation seam construction method and construction device. The flexible-pier horizontal separation seam construction device comprises a combined drawing plate, the combined drawing plate comprises bottom drawing plates, hard foam plates, edge sealing drawing plates and top drawing plates, the hard foam plates are positioned above the bottom drawing plates and adjacently connected with the bottom drawing plates, first side faces of the hard foam plates are flushed with second side faces of the bottom drawing plates, the edge sealing drawing plates are positioned above the bottom drawing plates and adjacently connected with the bottom drawing plates, third side faces of the edge sealing drawing plates are adjacently connected with fourth side faces of the hard foam plates, the fourth side faces and the second side faces are oppositely arranged, the top drawing plates are positioned above the hard foam plates and the edge sealing drawing plates and adjacently connected with hard foam plates and the edge sealing drawing plates, fifth sides of the top drawing plates are top drawing plates are flushed with the first side faces. The construction method and the construction device have the advantages of deep seam, high seaming accuracy and good seaming accuracy.

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 a horizontal partition fracture of a flexible bridge pier. Background technique [0002] With the continuous development of my country's economy, the requirements for the quality of urban bridge construction are getting higher and higher, and the requirements for the landscape of bridges are also getting higher and higher, making bridges become a landscape of a city, or even become a city business card. [0003] At present, most of the bridges are multi-span bridges. Generally, the two ends of the multi-span bridges will be equipped with rigid abutments, and the middle piers are all set as flexible piers, so that when the bridge piers are subjected to the thrust of the pier top, A large horizontal displacement can occur within a safe range, and it is guaranteed that in the direction along the bridge, the ...
