Description

Technical Field

[0001] The invention relates to the field of bored cast-in-place piles, in particular to a high-efficiency slurry discharge device for bored cast-in-place piles. Background Art

[0002] Bored and cast-in-place piles refer to piles made by forming pile holes in the foundation soil by means of mechanical drilling, steel pipe squeezing or manual excavation at the construction site, and placing steel cages and pouring concrete in them. According to different hole-forming methods, cast-in-place piles can be divided into several categories, such as sinking pipe cast-in-place piles, bored and cast-in-place piles and excavated and cast-in-place piles. Bored and cast-in-place piles have been widely used in the foundations of structural engineering such as roads and railway bridges due to their mature construction technology, high bearing capacity and wide application range. During the construction process of bored and cast-in-place piles, concrete slurry needs to be discharged into the casing for pouring, so a slurry discharge device is required for operation. The existing slurry discharge device is composed of a funnel and a bracket. When discharging concrete slurry, the speed is relatively slow, and the concrete entering the site blocks the slurry discharge port, which needs to be manually unblocked, which seriously affects the work efficiency. At the same time, the existing slurry discharge device has fixed specifications. When pouring bored and cast-in-place piles of different specifications, the slurry discharge port and the pouring port often do not fit together or cannot be contacted.

[0003] According to patent CN201921702788.5, a high-efficiency grouting device for bored cast-in-place piles relates to the field of building construction technology, specifically a high-efficiency grouting device for bored cast-in-place piles, comprising a grouting tank, an asynchronous motor is fixedly connected to the middle of the upper surface of the grouting tank, a protective cover located on the surface of the asynchronous motor is fixedly installed in the middle of the upper surface of the grouting tank, a vent is opened on one side of the upper surface of the grouting tank, and a feed pipe is fixedly installed on the other side of the upper surface of the grouting tank. The high-efficiency grouting device for bored cast-in-place piles utilizes the cooperation of a pushing column and a spiral pushing plate, and the spiral pushing plate is driven to rotate by the pushing column, and the concrete in the inner cavity of the grouting tank is pushed and poured by the spiral pushing plate, thereby avoiding the problems of serious concrete blockage and slow grouting speed of the grouting device of the traditional bored cast-in-place pile, and improving the working efficiency of the high-efficiency grouting device for bored cast-in-place piles.

[0004] The above patent is prone to unstable support during use, and the docking with the injection pipe by hoisting requires manual assistance, which is troublesome to operate and does not have the function of fine-tuning the position, so the device is manually pushed for alignment, resulting in high fatigue strength. In addition, after the device is used, it is inconvenient to clean the inside, and the concrete agglomeration is likely to affect subsequent use.
