A construction method of pile-pier integrated structure

Abstract

The invention discloses a construction method for a pile and pier integrated structure. The method includes the steps that an underground pile foundation is constructed at first, and then pile and pier connecting construction is performed; afterwards, an underground tool and a ground tool are installed in sequence, and hoisting and accurate adjusting of the pier position are conducted after installation is completed; and finally concrete is poured to the pile and pier connecting position. The underground tool is arranged between a pile ladling boundary line and a pier bottom, position adjustment of a pier is greatly facilitated after the pier is changed to be in a floor pier mode from a suspended pier form, and thus pier positioning precision can be controlled more easily. Moreover, by the adoption of a limiting space formed by longitudinal and transverse limiting baffles arranged at the top of the underground tool, when the pier is inserted into the limiting space, the pier can be preliminarily positioned naturally, and therefore the pier can be accurately positioned only through fine adjustment of the pier position on this basis, and the process of pier positioning is simplified.

Description

technical field [0001] The invention relates to a pile foundation and a bridge pier, in particular to a construction method for an integrated structure of a pile foundation and a bridge pier. Background technique [0002] The pile foundation is composed of foundation piles buried in the ground and caps connected to the pile tops, and bridge piers are piers built above the caps for support. Existing pile foundations and bridge piers are mainly used for vertically supported buildings such as bridges, and the loads they bear are also vertically directed to the ground, so there are very high requirements for the compressive capacity of pile foundations and bridge piers, but for some For buildings with lateral load or bending moment, the existing pile foundations and bridge piers lack sufficient resistance to pullout and flexure, resulting in the need for a large number of reinforcements when applied to these buildings, and there is a lack of applicable standards or methods that ...
