Embodiment Construction

[0029] The present invention is introduced below by accompanying drawing.

[0030] figure 1 The structure of an excavation device 100 for excavating a single hole for roadbed filling according to the present invention is shown. Such as figure 1 As shown, the digging device 100 includes a frame 10 . The frame 10 includes a frame body 13, and the frame body 13 is in the shape of a rectangular plate. A support plate 14 is provided on the edge of the upper end surface of the frame body 13 , and the support plate 14 is arranged on opposite short sides of the frame body 13 . A plurality of guide posts 11 are arranged between the support plates 14 , the guide posts 11 are above the frame body 13 and on the same horizontal plane, and the guide posts 11 are parallel to each other. For example, in figure 1 In the illustrated embodiment, the frame 10 is provided with two guide posts 11 . The structure of the rack 10 is simple, easy to install, and low in manufacturing cost.

Abstract

The invention provides a device for digging out roadbed filler single holes. The device comprises a rack, a power mechanism, a first drill pipe and a hydraulic propelling system, and further comprisesat least one second drill pipe, wherein a guide column is arranged on the rack; the power mechanism is arranged on the guide column and can move along the guide column; the first drill pipe is mounted on the rack; a drill bit is mounted at the front end of the first drill pipe; the rear end of the first drill pipe is detachably connected with a connecting part of the power mechanism in a drivingmode; and the hydraulic propelling system is used for propelling the drill pipe to drill; and the second drill pipes can be inserted in space between the first drill pipe and the power mechanism so asto increase the digging-out length. The invention further provides a method for digging out the roadbed filler single holes. In the method, digging-out operation can be implemented by the device.

Description

technical field [0001] The invention relates to the field of high-speed railway roadbed maintenance equipment, in particular to a digging device for digging a single hole for roadbed filler. The invention also relates to an excavation method for a single hole of roadbed filler using the excavation device. Background technique [0002] In recent years, with the rapid development of high-speed railways, large-scale high-speed railways have been built in my country, which has brought great convenience to people's travel. However, during the operation of high-speed railways, there will be some disease problems in the high-speed railway embankment, for example, the embankment will appear arching phenomenon due to the expansion material contained in the embankment bed filler or the instability of the embankment foundation structure. [0003] From top to bottom, the subgrade of high-speed railway is track slab, supporting layer, surface layer of subgrade bed, bottom layer of subgr...
