The offshore circular bearing platform reinforcing steel bar partition reinforcement treatment construction method can be suitable for solving the problem of connection of the bored piles and the bearing platform reinforcing steel bars during offshore large bridge foundation construction, it is guaranteed that the bored piles and the bearing platform better form a whole, and therefore the overall construction quality is guaranteed.

Description

Technical Field

[0001] The present invention belongs to the field of bridge construction, and particularly relates to a construction method for reinforcing the cut-off of steel bars of a circular cap in the sea. Background Art

[0002] In the construction of large-scale bridges in the sea, the construction of the pile foundation of the bridge usually starts with the construction of bored piles and then the construction of the cap. After pouring the bored piles, it is necessary to do a good job in the connection treatment of the steel bars of the bored piles and the steel bars of the cap. If the connection problem is not handled well, the overall foundation quality will be insufficient. Summary of the Invention

[0003] In order to properly handle the connection problem of the steel bars of the bored piles and the steel bars of the cap, a construction method for reinforcing the cut-off of steel bars of a circular cap in the sea is proposed.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0005] A construction method for reinforcing the cut-off of steel bars of a circular cap in the sea includes the following steps:

[0006] When there is a conflict between the steel bars of the cap and the steel bars of the bored piles, the steel bars of the cap are cut off.

[0007] Furthermore, the steel bars and the strip steel plates of the steel casing are spot-welded.

[0008] Furthermore, the tendon bundles and the steel casing are welded on both sides.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The construction method for reinforcing the cut-off of steel bars of a circular cap in the sea according to the present invention can be applied to the construction of the foundation of large-scale bridges in the sea to handle the connection problem of the steel bars of the bored piles and the cap, ensuring that the bored piles and the cap better form an integral body, thus ensuring the overall construction quality.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0019] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0020] Embodiment 1

[0021] A construction method for reinforcing and separating the steel bars of a circular cap on the sea includes the following steps: When there is a conflict between the cap steel bars and the bored pile steel bars, the cap steel bars are cut off. The steel bars and the strip steel plates for cutting the steel casing are spot welded; the steel bar bundles and the steel casing are welded on both sides.

[0022] The above method is applicable to dealing with the connection problem between the bored pile and the cap steel bars during the construction of the foundation of a large bridge on the sea, ensuring that the bored pile and the cap better form an integral body, thereby ensuring the overall construction quality. The on-site operation is simple and fast, and the treatment effect is good.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
