Abstract

The invention relates to a reinforcement cage structure for a karst area pile foundation, and relates to the technical field of building construction. The structure comprises a reinforcing steel bar outer frame and a reinforcing steel bar inner frame; the reinforcing steel bar outer frame comprises a plurality of outer main reinforcements and a plurality of outer hoop steel plates fixedly connected with the peripheries of the outer main reinforcements; the reinforcing steel bar inner frame comprises a plurality of inner main reinforcements and a plurality of inner hoop steel plates fixedly connected with the peripheries of the inner main reinforcements; and reinforcing rib frames are arranged on the side walls, away from the inner main reinforcements, of the outer hoop steel plates and located between the reinforcing steel bar outer frame and the reinforcing steel bar inner frame. The reinforcement cage structure for the karst area pile foundation and a pile foundation construction method have the advantages that the overall structural strength of the reinforcement cage is effectively improved, and therefore the foundation pile construction quality is improved.

Description

technical field [0001] The application relates to the technical field of building construction, in particular to a steel cage structure for pile foundations in karst areas and a pile foundation construction method. Background technique [0002] The karst area refers to the special landform formed by the long-term dissolution of soluble rocks such as limestone and dolomite by corrosive water; , The enhanced permeability usually easily causes problems such as insufficient bearing capacity of the foundation, collapse of the roof of the underlying karst cave, subsidence of the foundation, uneven settlement of the foundation, etc., which have a great impact on the construction and use of the project. [0003] The relevant authorization announcement number is the Chinese patent of CN108589718U, discloses a kind of pile foundation construction method in karst area, comprises the following steps: Utilize rotary drill and percussion drill to carry out advanced drilling; Carry out an...
