Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing of description and specific embodiment:

[0036] Such as figure 1 shown. The slag cleaning machine used for pile bottom sediment cleaning includes slag cleaning device 1, main controller 6, bracket 9, distribution box 8, lifting device, horizontal moving device, floating water cable 4, etc.

[0037] The structure of the slag removal device 1 is as figure 2 As shown, the slag removal device includes an outer cover 15, and the outer cover 15 is provided with a slag suction pipe 14 for absorbing sediment. 15, the slag suction pipe inlet 3 at the bottom of the slag suction pipe 14 spreads outwards in a trumpet shape; at least three layers of sediment filter screens 13 are arranged between the outer cover 15 and the slag suction pipe 14, and the sediment filter screen 13 The diameters of the mesh holes decrease sequentially from top to bottom, the height of the position of the ...

Abstract

The invention discloses a sediment removal machine for removing sediment at the bottom of a pile and a working method thereof. The sediment removal machine comprises a sediment removal device and a main controller for controlling work of the sediment removal device. The sediment removal device comprises an outer cover, a sediment suction tube for sucking the sediment is arranged in the outer cover, and the bottom end of the sediment suction tube extends out of the outer cover so that the sediment at the bottom of the pile can be sucked into the outer cover. At least one layer of sediment filter screen is arranged between the outer cover and the sediment suction tube. The positions where the sediment filter screens are located are lower than an outlet of the sediment suction tube. A water outlet is formed in the bottom surface of the outer cover so as to discharge return mud flowing down the sediment filter screens. A sediment amount sensor is arranged on the upper portion of the inner side face of the outer cover and connected with the main controller. Mud displacement does not exist, mud pouring is not needed, the automation degree is high, operability is high, the sediment removal efficiency and effect are improved, the hole collapse risk caused by mud displacement is avoided, and the problem that the environment is polluted because a large amount of mud is used is solved.

Description

technical field [0001] The invention relates to the technical field of pile bottom sediment cleaning in geotechnical engineering, in particular to a pile bottom cleaning machine and a working method thereof, and is especially suitable for bored pile bottom cleaning. Background technique [0002] Bored pile is one of the main foundation forms widely used at the present stage. It has the advantages of high bearing capacity, small settlement, flexible and convenient fabrication, and wide application conditions. It is widely used in the foundation of construction engineering and bridge engineering. However, during the construction of the pile foundation, limited by the construction technology and construction quality, before the final hole and before concrete pouring, a certain thickness of relatively weak sediment is often formed at the bottom of the pile. In particular, it is difficult to effectively control the sediment at the bottom of super-long cast-in-situ piles. Many eng...
