Problems solved by technology

[0005] The purpose of the present invention is to solve the increasing demand for the construction of cross-river and sea-crossing tunnels in the prior art. However, during the construction of underwater tunnels, it is not uncommon to encounter boulders in front, and it is difficult to quickly deal with them, which affects tunnel construction. Due to the problems of high efficiency and safety, a device and method for cutting the boulder in front of the tunnel by using high-pressure water are proposed

Abstract

The invention discloses a method for cutting a boulder in front of a tunnel by using high-pressure water. The method comprises the following steps that step one, first water isinjected into a water storage tank, then a base isplaced on a moving mechanism and sent into the tunnel; step two, then according to the environmental conditions in the tunnel, the height of a water cutting device is adjusted by a servo motor and a screw, and then the angle of a water cutting mechanism is adjusted by a telescopic cylinder and a connecting rod; andstep three, the water cutting mechanism is finally openedto cut the boulder in the tunnel. The free adjustment of the water cutting mechanism of the device isrealized through the arrangement of adjusting mechanisms, so that the efficiency of the cutting process of the device on the boulderisimproved, and the efficiency and safety of the tunnel construction areimproved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a device and method for cutting boulders in front of tunnels by using high-pressure water. Background technique [0002] The subsea tunnel is to solve the traffic between the straits and bays without hindering the shipping of ships, and to build marine structures under the seabed for the passage of people and vehicles. [0003] After rapid development in recent years, high-pressure water jet technology has been widely used in production and processing due to its advantages of fast cutting speed, high cutting surface finish, narrow slit, and environmental protection and pollution-free cutting process. At present, high-pressure water cutting machines are divided into two categories, one is robotic water cutting, and the other is table water cutting machines. [0004] However, there is an increasing demand for the construction of cross-river and sea-crossing tunnels. Ho...
