Construction of Pile Foundation Structure and Construction Method by Rotary Drilling Rig

Abstract

The application relates to a pile foundation structure constructed by a rotary drilling rig, which belongs to the field of building construction, and includes a pile body along the vertical direction, a steel cage skeleton is arranged in the pile body, and a fixing part is arranged on the pile body near the top of the pile body , the fixing part is arranged along the circumferential direction of the pile body, multiple sets of fixing parts are arranged at the position of the fixing part on the reinforcement cage skeleton, and the multiple sets of fixing parts are arranged at even intervals along the vertical direction, and the fixing parts are composed of a plurality of fixing steel bars, A plurality of fixing steel bars are evenly spaced along the circumference of the reinforcement cage skeleton, and the fixing reinforcement bars extend into the fixing portion toward a direction away from the reinforcement cage skeleton. The present application has the effect of facilitating the reduction of the occurrence of reinforcement cage floating.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a pile foundation structure constructed by a rotary drilling rig and a construction method thereof. Background technique [0002] The pile foundation constructed by the rotary drilling rig generally refers to the pile type constructed by the rotary drilling rig, also known as the rotary drilling cast-in-situ pile. Big labor costs. [0003] Existing authorized announcement number is that the Chinese patent of CN210827441U discloses a kind of rotary-dug bored cast-in-situ pile structure, comprises ground, and the inside of described ground is provided with borehole, and the inside of described borehole is placed with main reinforcement, and the inside of described main reinforcement Stirrups are connected to the outside, and a limit ring is provided at the bottom of the borehole close to the main reinforcement. There are two limit rings in total, and the two limit ri...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that in the process of pouring the concrete of the rotary excavation pile, if the construction personnel operate improperly or the concrete pouring speed is too fast, the reinforcement cage will appear to float, although the use of the partition board can play a certain role. The limiting effect, but it is still easy to appear that the partition is lifted by the steel cage
