Description
Technical field
The present invention relates to bridge construction technical fields, specifically, being that be related to a kind of flexible pier horizontal subdivision disconnected
The construction method and its constructing device of seam.
Background technology
With the continuous development of China's economy, the requirement for Urban Bridge Construction quality is also higher and higher, and to bridge
Landscape requirement it is also higher and higher so that bridge becomes a line of scenery in a city, even becomes city
Business card.
Currently, most bridge is multispan bridge, the larger abutment of rigidity can be arranged in the both ends of general multispan bridge,
And middle pier is then disposed as flexible pier so that, can be in the range of safety when bridge pier is when by pier top thrust
It is interior that larger horizontal displacement occurs, and ensure on the direction along bridge, the horizontal connection between the bridge pier of bridge by completely every
It is disconnected so that each bridge pier individually bears the brake force transmitted on bridge or tractive force.Further, since the horizontal thrust of bridge pier is by each
The rigidity of pier is distributed so that the horizontal thrust very little being assigned on each bridge pier, the safety that protection bridge uses.
However, in order to ensure the landscape of bridge, generally can ornamental blocks be set in the outside of bridge pier, to play dress to bridge
Decorations act on, and in order to enable ornamental blocks can normal use, need to ensure the whole stress that ornamental blocks are not involved in bridge pier.But
Since larger horizontal displacement can occur when by horizontal thrust for bridge pier, often so that ornamental blocks more or less can be by bridge pier
On horizontal thrust involve, lead to the damage of ornamental blocks, there are security risks.
And way conventional at present is that horizontal joint is cut into molding ornamental blocks, is subject to reduce ornamental blocks to the greatest extent
Horizontal thrust on bridge pier, still, there are depth as shallow, cutting difficulty for the horizontal joint which is cut into greatly, at seam
The problems such as size and effect can not ensure, construction safety risk is high and of high cost.Further, since the horizontal joint being cut into
Depth as shallow so that ornamental blocks still can be caused ornamental blocks to be easily damaged, there are security risks by the horizontal thrust on bridge pier.
Invention content
To solve the above-mentioned problems, the main object of the present invention is to provide a kind of easy to operate, big at seam depth, smart at seam

Extruding and shift.
Then, the second supporting template 8 is installed along the circumferential profile of the top surface of the bridge pier elementary section 91 poured, and is formed and is waited for
Pour cavity 93.
In addition, completing the first bottom pumping board 20, the first edge sealing pumping board 40, the first top layer pumping board 50, the second bottom pumping board
200, after the installation of the second edge sealing pumping board 400, the second top layer pumping board 500 and the second supporting template 8, each pumping board and second are supported
The installation site of template 8 is checked and is corrected, and is prevented each pumping board and the position of the second supporting template 8 from large error occur, is kept away
Exempt from influence horizontal subdivision breaking joint at seam size, at seam precision and at seam quality.
It pours and curing step：
As shown in fig. 6, carrying out concreting to cavity 93 to be poured, and the concrete after pouring is conserved, shape
The bridge pier elementary section of Cheng Xin.
Demoulding step：
As shown in Figure 7 and Figure 8, first, after the completion of concrete curing, the first bottom pumping board 20 is released, the first edge sealing is taken out
Plate 40, the first top layer pumping board 50 are fixedly connected with the first supporting template 7；Similarly, the second bottom pumping board 200, second is released
Edge sealing pumping board 400, the second top layer pumping board 500 are fixedly connected with the first supporting template 7.
