Embodiment Construction

[0032] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. As a part of this specification, the principles of the present invention will be described through examples. Other aspects, features and advantages of the present invention will become clear through the detailed description. In the referenced drawings, the same reference numerals are used for the same or similar components in different drawings.

[0033] It should be noted that all directional indications (such as up, down, outside, inside, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly. where "before" corresponds to Figure 1 to Figure 2 On the left si...

Abstract

The invention discloses a rock roadway bursting and cutting united tunneling device and a control method thereof. The rock roadway bursting and cutting united tunneling device comprises a rock mass, an impact drill for drilling the rock mass, an injector for injecting a bursting agent into a drill hole formed in the rock mass through the impact drill and a tunneling machine for forward tunneling after the bursting agent acts in the drill hole for a period of time and the rock strength is reduced. The bursting agent is injected into a pre-processed expanding hole to reduce the rock strength byadopting a non-explosion tunneling method, and construction is performed by using a tunneling method to achieve the purpose of tunneling in a non-explosion way. An explosion way is not used in the tunneling process, the pollution is small, the cost is low, a construction period is short, the danger of landslide is effectively avoided, and lots of tunneling problems caused by the fact that the explosion way cannot be used in the cities are solved.

Description

technical field [0001] The invention belongs to the technical field of rock excavation, and in particular relates to a rock roadway swelling and cutting combined excavation device and a control method thereof. Background technique [0002] At present, roadway excavation is very important in the current urban construction. In the roadway excavation work, there are rocks with high hardness. The traditional method uses blasting to excavate, but when encountering railways and building excavation work, the blasting method will cause Violent vibrations of superstructures and railways cause dangers such as landslides, which have great obstacles to construction and cause harm to people and property, and prolong the construction period and increase the difficulty and cost of construction. [0003] Therefore, a fast and efficient tunneling technology and method is designed to solve the above problems. Contents of the invention [0004] Based on the above deficiencies in the prior a...
