Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.
It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein. Accordingly, the scope of the present invention is not limited by the specific embodiments disclosed below.
As shown in fig. 1, the large-particle-size sediment cleaner at the bottom of the ultra-deep pile hole provided by the present application comprises a conduit 100, a cylinder 200 and a filter cover 300. The guide tube 100 and the cylinder 200 each have two ports communicating with each other, and since the guide tube 100 and the cylinder 200 are vertically placed in the stake hole in use, the two ports of the guide tube 100 and the cylinder 200 are now named as an upper port and a lower port for convenience of description. The cylinder 200 is sleeved on the lower part of the guide pipe 100, the axis of the cylinder 200 and the axis of the guide pipe 100 extend in the same direction, the lower port of the guide pipe 100 is positioned at the inner side of the lower port of the cylinder 200, and the lower port of the guide pipe 100 is higher than the lower port of the cylinder 200; the filter cover 300 is arranged in the cylinder 200, specifically in an annular cavity between the cylinder 200 and the conduit 100, a through hole is arranged in the middle of the filter cover 300 for the conduit 100 to pass through, the filter cover 300 is sleeved outside the conduit 100 through the through hole, and the edge of the filter cover 300 is fixed on the inner wall of the cylinder 200.
As shown in fig. 2, when large-particle-size sediments at the bottom of a pile hole are cleaned, the cleaner provided by the application is placed into the pile hole through the lifting mechanism 400, and is lifted by 30-40cm after being sunk into the bottom of the pile hole, so that a slurry discharge channel is reserved between the lower port of the cylinder body 200 and the bottom of the pile hole. Then, the upper port of the guide pipe 100 is connected to the grouting pump 500. When no mud is discharged from the lower port of the conduit 100, the mud pressure inside and outside the lower port of the conduit 100 is the same. When mud is pressed into the guide pipe 100 by the grouting pump 500, the mud entering the guide pipe 100 is discharged from the lower port of the guide pipe 100 at a certain flow rate and rushes to the bottom of the pile hole, so that sediments with large particle sizes at the bottom of the pile hole are flushed away, and the sediments rise to a certain height along with the mud.
In the process of discharging the slurry from the lower port of the guide pipe 100, the pressure in the region between the outer side of the lower port of the guide pipe 100 and the lower port of the cylinder 200 is reduced, so that a downward suction force is generated in the cylinder 200, and the flushed large-particle-size sediment is sucked into the cylinder 200. In the process that the sediment and the slurry descend in the cylinder body 200, the sediment is intercepted by the filter cover 300, and the slurry flows downwards through the filter cover 300, so that the collection of the sediment with large particle size is realized. After grouting for a certain time, the cleaner is lifted to the ground through the lifting mechanism 400, and the sediments in the filter cover 300 are poured out. In order to ensure the suction force in the negative pressure region, a height difference of about 10-25cm is formed between the lower port of the cylinder 200 and the lower port of the guide tube 100, and the diameter difference between the lower port of the cylinder 200 and the lower port of the guide tube 100 is 0.2-0.3 times of the inner diameter of the guide tube 100.
Referring to fig. 1 again, further, in order to prevent the filter cap 300 from being blocked and difficult to form a negative pressure region when more filter residues are deposited on the filter cap 300, in the cleaning device provided by the present application, the filter cap 300 is set to be a cone shape, specifically, a cone structure with a thick top and a thin bottom, which can increase the effective area of the filter cap 300, so that the filter residues are firstly accumulated at the lower part of the cone structure to prevent the filter cap 300 from being blocked.
In a preferred embodiment, the cartridge 200 includes a large-diameter straight cartridge 210 and a small-diameter straight cartridge 220, and the lower port of the catheter 100 is located in the small-diameter straight cartridge 220. The inner diameter of the large-diameter straight cylinder 210 is larger than that of the small-diameter straight cylinder 220, and the filter housing 300 is arranged in the large-diameter straight cylinder 210; further, the large-diameter straight cylinder 210 and the small-diameter straight cylinder 220 are connected by the tapered cylinder 230, so that the slurry smoothly passes through the tapered cylinder 230 and the small-diameter straight cylinder 220 from the large-diameter straight cylinder 210 and then is discharged out of the pipe 100.
Further, the conduit 100 and the cylinder 200 are connected by a connecting rod 610, and the connecting rod 610 is distributed between the conduit 100 and the cylinder 200 in an annular array, so that the relative position between the cylinder 200 and the conduit 100 is positioned, and the slurry and the sediment are not hindered from flowing into the cylinder 200.
In order to connect the barrel 200 with the lifting mechanism 400 conveniently, a suspension arm 620 is arranged on the barrel 200, a lifting ring 630 is arranged on the suspension arm 620, the lifting mechanism 400 can be selected from a crane or a hoist, and the lifting ring 630 is connected with the crane or the hoist through a traction rope 640 and used for controlling the cleaner to lift and sink. Specifically, the suspension arms 620 are uniformly distributed on the periphery of the guide pipe 100, one end of each suspension arm is fixed to the cylinder 200, and the other end of each suspension arm is fixed to the guide pipe 100.
