Description

Technical Field

[0001] The present invention relates to the technical field of bridge support, and more specifically, to a pile cap foundation and a construction method thereof. Background Art

[0002] The cap is an important part connecting the pile foundation and the bridge. It is necessary to transfer the load on the bridge to the pile foundation. The cap plays a decisive role in whether the bridge is stable. The cap is usually embedded in the top of the pile foundation, and the bridge is embedded in the top of the cap. The cap, pile foundation and bridge are all rigidly connected.

[0003] The existing patent number 202122562774.1 is a pile cap foundation and its construction method. When in use, the cap and the pile foundation can produce relative displacement in the horizontal direction through the setting of the fixed component. The gravel layer and the rubber layer can make the cap and the pile foundation produce relative displacement in the vertical direction, which plays a buffering role and extends the service life of the bridge.

[0004] Based on the above, the inventors found that: the above patent adopts a buffer component and a gravel layer and a rubber layer to achieve a buffer effect. Although it can extend the service life of the bridge, the firmness of the bridge support structure is relatively poor. When the bridge shakes, problems such as concrete cracking and steel bar bending will still occur. Therefore, in view of this, the existing structure is studied and improved, and a pile cap foundation and a construction method thereof are provided, in order to achieve a more practical purpose. Summary of the invention
