Embodiment Construction
[0040] The following is attached Figure 1-5 The application is described in further detail.
[0041] The embodiment of the application discloses a construction method for improving the concrete density of bored piles. Include the following steps:
[0042] S1: Insert the conduit 1 into the pile hole 2, and install the vibrating device on the side wall of the conduit 1;
[0043] S2: Pour concrete into the conduit 1, the concrete flows out from the bottom of the conduit 1, part of the outflowing concrete is at the bottom of the pile hole 2, and part of it is turned up along the outer wall of the conduit 1;
[0044] S3: Before the conduit 1 is lifted upwards, start the vibrating device. After starting the vibrating device, the vibration source of the vibrating device rotates intermittently around the conduit 1. The vibrating device vibrates and vibrates the concrete through the conduit 1, and vibrates in the Lift the catheter 1 upwards at the same time, so that the catheter 1 ...

The invention relates to a construction method for improving the concrete compactness of a drilled pile. The construction method comprises the following steps that S1, a guide pipe is guided into a pile hole, and a vibrating device is mounted on the guide pipe; S2, concrete is poured into the guide pipe and flows out of the bottom of the guide pipe, one part of the flowing-out concrete is located at the bottom of the pile hole, and the other part of the flowing-out concrete overturns along the outer wall of the guide pipe; S3, before the guide pipe is lifted upwards, the vibrating device is started, the vibrating device vibrates, the concrete is vibrated through the guide pipe, the guide pipe is lifted upwards when the vibrating device vibrates, and the guide pipe vibrates while being lifted; S4, then the guide pipe is lifted upwards by a certain distance, the vibrating device is closed, concrete continues to be poured into the guide pipe, after pouring and before the guide pipe is lifted upwards, the vibrating device is started again, the guide pipe is lifted upwards when the vibrating device vibrates, and the guide pipe vibrates while being lifted; and S5, the step S4 is repeated. The problems that the concrete compactness in the pile hole is low, and the pile forming quality is poor are solved.
Description
technical field [0001] The application relates to the field of bored piles, in particular to a construction method for improving the concrete compactness of bored piles. Background technique [0002] Cast-in-situ pile refers to the pile hole formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation at the project site, and a pile made by placing a steel cage and pouring concrete in it. According to different hole-forming methods, Cast-in-situ piles can be divided into several categories such as immersed pipe piles, bored piles and bored piles. [0003] Bored cast-in-place piles are formed by directly opening holes on the designed pile positions with a circular cross-section. After the holes are formed, a reinforcement cage is placed in the holes, and concrete is poured through the conduit. A part of the concrete poured into the pile hole is at the bottom of the pile hole, and a part is turned up along the outer wall of the cond...
