Detailed Embodiment

[0022] The present utility model will be further described below with reference to the drawings.

[0023] A slag cleaning tool for bored cast-in-place piles, comprising a slag cleaning cylinder 1, a slag cleaning support 2 and a slag cleaning box 3. The slag cleaning support 2 is fixed inside the slag cleaning cylinder 1. A floating plate 4 that can move up and down relative to the slag cleaning support 2 is provided on the slag cleaning support 2. In this device, the floating plate 4 can move up and down relative to the slag cleaning support 2, ensuring that the floating plate 4 can be stably separated from or covered with the slag cleaning support 2, and ensuring the stability of the use of this device. The slag cleaning box 3 is detachably installed inside the slag cleaning cylinder 1, and the slag cleaning box 3 is adapted to the slag cleaning support 2, so as to collect the muck into the slag cleaning box 3. During the slag cleaning interval, the muck in the slag cleaning box 3 can be quickly replaced by replacing the slag cleaning box 3, thereby improving the construction convenience and the slag cleaning efficiency.

[0024] During use, the slag cleaning cylinder 1 is placed into the cast-in-place pile. This device sinks in the cast-in-place pile. The floating plate 4 is affected by water and floats relative to the slag cleaning support 2, so that the slurry water with muck flows into this device. After this device sinks in place, this device is lifted. The floating plate 4 is affected by water and abuts against the slag cleaning support 2. The slag cleaning support 2 screens the slurry water, so that the large-particle muck remains in the slag cleaning cylinder 1, and the large-particle muck is collected in the slag cleaning box 3.

[0025] A plurality of guide rods 5 are provided on the slag cleaning support 2. The floating plate 4 is installed on the slag cleaning support 2 in a liftable manner through the guide rods 5. Preferably, the floating plate 4 is provided with guide holes that cooperate with the guide rods 5. The aperture of the guide holes is larger than the diameter of the guide rods 5, so as to ensure that the floating plate 4 can float relative to the guide rods 5.

[0026] The slag cleaning support 2 is of a conical structure. A plurality of through slots 2-1 are evenly distributed on the slag cleaning support 2. The large-particle muck is screened through the through slots 2-1, so that the large-particle muck remains in the slag cleaning cylinder 1.

[0027] The slag cleaning support 2 is connected inside the slag cleaning cylinder 1 through a connecting rod 6, so that a slag collection groove is formed between the slag cleaning support 2 and the slag cleaning cylinder 1. The large-particle muck is collected into the slag cleaning box 3 through the slag collection groove.

[0028] The slag cleaning box 3 is of an annular structure. An annular opening is provided at the top of the slag cleaning box 3 for collecting large-particle muck. Among them, the inner side of the annular opening abuts against the slag cleaning support 2, and the outer side of the annular opening abuts against the slag cleaning cylinder 1, so as to ensure that the muck completely falls into the slag cleaning box 3. Since the slag cleaning box 3 is of an annular structure, a liquid flow channel 3-1 is formed in the middle of the slag cleaning box 3. The liquid flow channel 3-1 is adapted to the slag cleaning support 2, that is, the slag cleaning support 2 is arranged opposite to the liquid flow channel 3-1, so that during the sinking process of this device, the slurry water flows into this device through the slag cleaning support 2.

[0029] A limiting ring 1-2 is provided at the bottom of the slag cleaning cylinder 1, and the upper end surface of the slag cleaning box 3 abuts against the limiting ring 1-2 to prevent the slag from being discharged outside the device through the gap between the slag cleaning cylinder 1 and the slag cleaning box 3.

[0030] An installation bracket 7 is provided at the bottom of the slag cleaning cylinder 1, and the slag cleaning box 3 is installed on the slag cleaning cylinder 1 through the installation bracket 7. The installation bracket 7 includes a connecting column 7-1 and a bottom plate 7-2. The bottom plate 7-2 is installed at the bottom of the slag cleaning cylinder 1 through the connecting column 7-1. A through hole 7-3 is provided in the middle of the bottom plate 7-2, and the through hole 7-3 is adapted to the slag cleaning box 3, that is, the through hole 7-3 is arranged opposite to the liquid flow channel 3-1 to facilitate the slag slurry water to flow into the device.

[0031] A connecting plate 1-1 is provided on the outer side wall of the slag cleaning cylinder 1, and a locking plate 3-2 is provided on the side wall of the slag cleaning box 3. The connecting plate 1-1 and the locking plate 3-2 are connected by bolts to ensure the locking of the slag cleaning cylinder 1 and the slag cleaning box 3, prevent the slag cleaning cylinder 1 and the slag cleaning box 3 from being misaligned, and thus prevent the slag from being discharged outside the device through the gap between the slag cleaning cylinder 1 and the slag cleaning box 3.

[0032] To improve the filtering efficiency of the device, a plurality of liquid discharge holes 3-3 are provided on the side wall of the slag cleaning box 3 to improve the outflow of the slag slurry water outside the device.
