In-tunnel rapid turning construction equipment and method for multiple connection channels

Abstract

The invention discloses in-tunnel rapid turning construction equipment and method for multiple connection channels. The construction equipment comprises a support frame, a circular pipe fitting, a sleeve frame, an upper rolling wheel and a driving motor, wherein the circular pipe fitting is fixedly connected to the inner wall of the middle of the support frame, the sleeve frame is slidably connected to the inner wall of the lower side of the support frame, the upper rolling wheel is fixedly connected to the inner wall of the upper side of the support frame, the driving motor is fixedly connected to the inner wall of the lower side of the support frame, a lower rolling wheel is installed on the front face of the driving motor, a first belt wheel is fixedly connected to the front face of thelower rolling wheel, and a transmission mechanism is installed on the outer surface of the first belt wheel. When the construction equipment is used, the intermittent drilling effect is achieved through cooperative use of structures such as a guide wheel, an oval block and a lifting base; the pre-dedusting effect is achieved through cooperative use of structures such as a rotating shaft, a secondbelt wheel and a second belt; and after the sleeve frame is rotated, the double-face drilling effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a construction equipment and method for rapid U-turn in tunnels for multiple communication passages. Background technique [0002] The connecting passage is generally set in the middle of the two tunnels, and it becomes a passage between the two tunnels, which plays the role of communication, drainage and fire prevention. The safety factor of the tunnel will also be greatly increased, so it is called "escape channel". Generally, when the length of the two-lane tunnel is greater than 600m, it is necessary to set up a communication channel. For a long-distance tunnel, multiple communication channels must be set up. [0003] In the construction process of the communication channel, it is generally necessary to install multiple horizontal and vertical pipe fittings to ensure the stability of the construction process of the communication channel. In order to en...

Problems solved by technology

[0003]In the construction process of the communication channel, it is generally necessary to install multiple horizontal and vertical pipe fittings to ensure the stability of the construction process of the communication channel. In order to ensure the installation process These pipe fittings generally need to be drilled in an orderly manner. In the prior art, the pipe fittings are generally manually drilled from left to right. Obviously, this method requires a lot of manpower and is very expensive. It is difficult to ensure that the distance between each hole slot is equal, which brings great challenges to the subsequent installation work. At the same time, some pipe fittings need to be drilled in both directions. The existing technology is difficult to ensure stable drilling work after turning around. It brings great challenges. In particular, the pipe fittings are set in the tunnel, and a large amount of impurities and dust will adhere to the outer surface. If they are not disposed of in time, it will affect the subsequent double-sided drilling work
