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

Embodiment Construction

[0038] The following is attached Figure 1-4 The application is described in further detail.

[0039] The embodiment of the present application discloses a pile foundation structure constructed by a rotary drilling rig.

[0040] refer to figure 1 and figure 2 , a pile foundation structure constructed by a rotary drilling rig, comprising a pile body 1 along the vertical direction, the pile body 1 itself is made of concrete material, a reinforcement cage skeleton 2 is arranged inside the pile body 1, and the reinforcement cage skeleton 2 is assembled in a reinforcement field, And after the pile hole is cleared, it is hoisted into the pile hole. The reinforcement cage skeleton 2 includes a plurality of main reinforcements and a plurality of stirrups. The plurality of main reinforcements are evenly arranged along the circumferential direction, and the stirrups are welded with each main reinforcement in a ring shape; the pile body 1 and is located near the top of the pile body ...

Abstract

The invention relates to a rotary drilling rig construction pile foundation structure, and belongs to the field of building construction. The rotary drilling rig construction pile foundation structurecomprises a pile body in the vertical direction, a reinforcement cage framework is arranged in the pile body, and a fixing part is arranged on position, close to the top end of the pile body, on thepile body and is arranged in the circumferential direction of the pile body; and a plurality of sets of fixing pieces are arranged at the positions, where the fixing part is located, of the reinforcement cage framework, the multiple sets of fixing pieces are evenly arranged at intervals in the vertical direction, each fixing piece is composed of a plurality of fixing steel bars, the multiple fixing steel bars are evenly arranged at intervals in the circumferential direction of the reinforcement cage framework, and the fixing steel bars extend into the fixing part in the direction away from thereinforcement cage framework. The rotary drilling rig construction pile foundation structure has the effect that the situation that a reinforcement cage floats can be reduced conveniently.

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...
