A deep hole pile slag removal system

Abstract

The invention discloses a slag removing system for a deep hole pile. The slag removing system comprises a sedimentation pool, a slurry pool and a slurry pump arranged in the slurry pool, and further comprises a slag removing barrel used for being placed into the hole pile, and a lifting device used for lifting the slag removing barrel. An outlet of the slurry pump is connected with a grouting guiding pipe. A sleeve pipe mechanism which can allow the grouting guiding pipe to penetrate through is coaxially arranged in the middle of the slag removing barrel; the diameter of the slag removing barrel is smaller than that of the hole pipe with slag to be removed, and thus a space which can allow the to-be-removed broken slag to pass through is formed between the slag removing barrel and the inner wall of the hole pipe with the slag to be removed; a filter net which can allow slurry to flow through is arranged at the bottom of the slag removing barrel, and the hole diameter of the filter netis smaller than the minimum diameter of the to-be-removed broken slag; and lifting lugs are further arranged on the slag removing barrel, and a lifting rope of the lifting device is connected to the lifting lugs. The slag removing system has the advantages that structural design is reasonable, operation is convenient, the slag removing system can be suitable for the hole piles with various depths,slag removing is complete, the efficiency is high, the pile forming quality in the later period is advantageously improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a slag cleaning system for deep hole piles. Background technique [0002] Hole cleaning is to clean the bottom of the hole. If the sediment is too thick, it is easy to cause interlayers, broken piles, or even waste piles when pouring concrete underwater. Therefore, it is very necessary to clear the holes of the cast-in-place piles. At present, the clearing of hole piles mainly uses a mud pump to input a certain proportion of mud into the conduit, and the pressured mud is discharged through the bottom of the conduit. The sediment at the bottom of the hole is suspended under the impact of the sprayed mud, and the mud and sediment in the hole run upward along the pile hole, are discharged from the hole, enter the sedimentation tank, filter out the sediment in the mud, and then flow into the mud tank again, and then pass through the mud The pump rushes into the hole an...

Problems solved by technology

[0003] However, the sediment at the bottom of the hole is usually the gravel produced during the punching process. The gravel will also sink under its own gravity when it floats up with the mud. Therefore, the maximum floating height of the gravel is limited.

At present, for punched piles with a depth of less than 20 meters, high-power mud pumps can be used to blow them out of the hole with mud, but for punched piles with a depth greater than 20 meters, especially those with a depth of more than 30 meters, the gravel will rise with the mud. After reaching the highest point, it cannot continue to rise, and will eventually fall back to the bottom of the hole, making it impossible to completely remove the slag from the hole pile, which will affect the quality of the pile in the later stage
