Problems solved by technology

The inventor believes that rock fragmentation means that its utilization rate will be greatly reduced, and at the same time, the treatment of crushed stone will also increase the project cost; the traditional blasting method has problems such as large vibration, crushed stone splashing, and dust pollution, which seriously affect the safety of construction personnel and are not conducive to Environmental protection; at the same time, removing drilling and other equipment before blasting will affect construction efficiency
[0005] In the existing technology, domestic researchers have done less research and development on tunnel mobile hard rock micro-damage cutting devices, and there is no complete set of tunnel hard rock integrity excavation devices

Embodiment 1

[0037] In a typical implementation of the present invention, this embodiment discloses a tunnel hard rock micro-damage cutting device 12, which includes a columnar body and multiple reciprocating mechanisms, and the multiple reciprocating mechanisms are connected to the side of the columnar body. Each reciprocating mechanism can reciprocate along the radial direction of the columnar body. During this process, the reciprocating mechanism can protrude beyond the side of the columnar body when it moves outward. When the columnar body moves, the outer surface of the reciprocating mechanism The end just can touch the hard rock around, thereby completes cutting action; The front end of columnar main body is spike-like, so that enter drilling hole; The front end of cylindrical main body is also equipped with image sensor 15.

[0038] In this embodiment, the reciprocating mechanism uses a hydraulic cylinder 11, and the hydraulic cylinder 11 is also connected to other components in the ...

Embodiment 2

[0043]In a typical implementation of the present invention, this embodiment discloses a tunnel hard rock micro-damage cutting system, including a car body 13, a hard rock drilling construction unit, a hard rock cutting construction unit, a self-unloading tipping bucket 1, and a visual operation The terminal, wherein, the hard rock drilling construction unit, the hard rock cutting construction unit, the dump bucket 1 and the visual operation terminal are all installed on the vehicle body 13 .

[0044] The hard rock drilling construction unit in this embodiment uses the tunnel hard rock micro-damage cutting device 12 in Embodiment 1. Other mechanisms capable of expanding the borehole can also be used, and details will not be repeated here.

[0045] Further, the hard rock drilling construction unit includes a first power arm 4 and a drilling device 7, the first power arm 4 is installed on a crawler trolley, and the front end of the first power arm 4 is detachably connected to the...

Embodiment 3

[0063] In a typical implementation of the present invention, this embodiment discloses a method for micro-damage cutting of hard rock in tunnels. Using the system in Embodiment 2, the four columns of hydraulic cylinders 11 are respectively named as the first hydraulic cylinder 11, The second hydraulic cylinder 11, the third hydraulic cylinder 11 and the fourth hydraulic cylinder 11, wherein the first hydraulic cylinder 11 and the third hydraulic cylinder 11 are vertically arranged, and the second hydraulic cylinder 11 and the fourth hydraulic cylinder 11 are horizontally arranged, so the first hydraulic cylinder 11 and the third hydraulic cylinder 11 are arranged horizontally. One hydraulic cylinder 11 and the third hydraulic cylinder 11 can be called longitudinal hydraulic cylinder 11, and the second hydraulic cylinder 11 and the fourth hydraulic cylinder 11 can be called horizontal hydraulic cylinder 11, including the following steps:

Abstract

The invention discloses a tunnel hard rock micro-damage cutting device, system and method, and belongs to the technical field of underground engineering construction. The tunnel hard rock micro-damage cutting device, system and method have the advantages of being high in mechanization degree, good in rock integrity and easy to support; and while high excavation efficiency is guaranteed, damage to the natural environment can be reduced, the device comprises a columnar main body and a plurality of reciprocating motion mechanisms, wherein the reciprocating motion mechanisms are all connected to the side face of the columnar main body, the multiple reciprocating motion mechanisms can reciprocate in the radial direction of the columnar main body, the front end of the columnar main body is spine-shaped, and an image sensor is further installed at the front end of the main body.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a tunnel hard rock micro-damage cutting system and a construction method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the process of building high-speed railways in mountainous areas, the construction of tunnels often accounts for the largest proportion of the entire project workload, so the tunnel excavation speed and construction quality directly affect the social and economic benefits brought by high-speed railways. [0004] At present, in the process of tunnel excavation in my country, blasting is usually used in areas with good geological conditions. The blasting is accompanied by a large amount of rock being broken to separate it from the parent rock. The inventor believes that rock fragmentation me...
