Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0025] In the pile foundation underpinning process, the traditional construction method is changed, and the underpinning foundation pile is firstly constructed, and then the cap is poured. The present invention comprehensively considers the connection between the foundation pile and the cap in the pile foundation underpinning process, and proposes A new method for connecting fo...

Abstract

The invention relates to improvement in the pile foundation underpinning field, in particular to a connecting structure and method for foundation piles and a bearing platform in pile foundation underpinning. The connecting structure comprises an original pile foundation, the bearing platform, concrete, steel sleeves and anchor bolts, wherein the one or more underpinning foundation piles are arranged on one side of the original pile foundation, and underpinning foundation pile reserved main reinforcements stretch out from the underpinning foundation piles; the bearing platform is connected with the original pile foundation, and bearing platform reserved main reinforcements stretch out from the lower side of the bearing platform; the underpinning foundation pile reserved main reinforcements and the bearing platform reserved main reinforcements are wrapped by the concrete; the concrete is wrapped by the steel sleeves; and the steel sleeves and the concrete are fixed through the anchor bolts. The problem of new connection in pile foundation underpinning is solved successfully, and smooth proceeding of a reconstruction project of a bridge in a certain place is guaranteed.

Description

technical field [0001] The invention relates to improvements in the field of pile foundation underpinning, in particular to a connection structure and connection method between foundation piles and caps in pile foundation underpinning. Background technique [0002] When the ordinary pile foundation is connected with the cap, the pile foundation construction is generally carried out first, and the reserved main reinforcement of the pile foundation and the main reinforcement of the cap are anchored, and then the concrete pouring of the cap is carried out. [0003] The major drawbacks of the prior art are: [0004] 1. Underpinning foundation piles often settle, especially after they are stressed; [0005] 2. During the preparation process, the bearing platform is easily damaged due to uneven force. Contents of the invention [0006] Purpose of the invention: In order to provide a connection structure and connection method between foundation piles and caps in pile foundation...
