A suction type slag cleaner

Abstract

The invention provides a sucking-in type slag removing machine. The sucking-in type slag removing machine comprises a closed barrel body, at least one slag sucking pipe and a slag sucking device; a hoisting arm is installed on the top of the barrel body; the bottom segment of the barrel body is provided with a sealed slag outlet; the slag sucking pipe is installed in the barrel body in the axial direction of the barrel body; the inlet end of the slag sucking pipe stretches out of the bottom of the barrel body, and the outlet end of the slag sucking pipe is arranged in the barrel body; the slagsucking device is installed above the side portion of the outlet end of the slag sucking pipe, and is used for generating negative pressure sucking force in the barrel body and sucking and discharging slurry after a sediment-slurry mixture is separated; the sediment-slurry mixture in a drill hole / well enters the barrel body to be dispersed under the effects of the sucking force of the slag sucking device; sediment falls into the bottom segment of the barrel body, and the slurry is discharged outwards by the slag sucking device to be circulated. The sucking-in type slag removing machine belongs to an active slag removing manner, the slag removing machine can be used for removing large-particle-diameter stone slag and can also be used for removing slag in slurry holes and clean water holes,slag removing can be performed even though mud making and slag mixing are not needed, and the sucking-in type slag removing machine is high in slag removing effect and wide in using range.

Description

technical field [0001] The invention relates to the technical field of concrete pouring pile foundation construction in construction and traffic engineering and the field of well bottom dredging, in particular to a suction-type slag cleaner for removing sediment at the bottom of pile holes and silted sediment at the bottom of well holes. Background technique [0002] In the construction of the concrete pouring pile foundation project, whether it is the pile foundation drilling operation or the hole cleaning operation before pouring concrete, it is necessary to remove a large amount of sediment formed at the bottom of the pile hole. The cleaning method of the hole bottom directly determines the operation efficiency and cleaning. Therefore, it is very important to choose cleaning methods and cleaning tools scientifically and reasonably. In addition, similar problems are also faced in the operation of cleaning up the silt accumulated at the bottom of the wellbore. [0003] At ...

AI Technical Summary

Problems solved by technology

The cleaning effect of this slag cleaning method is obvious. Since the equipment used is relatively large and the installation and disassembly are complicated, it is usually only used for secondary hole cleaning.

This method uses the buoyancy of the mud at the bottom to discharge the sediment. Therefore, when the mud concentration is low or the diameter of the sediment block is large, it is difficult to clean the hole thoroughly.

[0007] The above three hole cleaning methods all use the suspension of mud to clean the drilling slag, but for the slag cleaning of the mud concentration is low or even the clear water hole, the slag cleaning progress is slow, and the slag cleaning is not thorough, and the relevant requirements cannot be met.

In addition, for some situations where slag falls in the follow-up work (such as lowering the steel cage) after the hole cleaning operation has been completed, all existing secondary hole cleaning measures cannot really solve the problem.
