Pipe piece dismounting device for waste tunnel expanding and using method thereof

Abstract

The invention discloses a pipe piece dismounting device for waste tunnel expanding and a using method thereof. The pipe piece dismounting device comprises a tunnel hole body, wherein a vehicle rail is arranged in the middle of the bottom of the tunnel hole body, and a vehicle body matched with the vehicle rail is arranged at the top of the vehicle rail; and L-shaped fixing seats connected with each other are arranged at the bottoms of the two sides of the vehicle body, and a servo motor B is arranged in the middle of the top of the vehicle body. According to the pipe piece dismounting device for waste tunnel expanding and the using method thereof, an arc-shaped cutting part is promoted to be adaptively adjusted according to the gap and the width of a pipe piece through an unfolding structure, so that the arc-shaped cutting part is unfolded to be attached to the crack of the pipe piece under the operation of three sets of driving force at the same time, and the grinding and digging work of the assembling position of the pipe piece is carried out; and two sets of brush plates are additionally arranged, so that broken slag on the two sides of the pipe piece is automatically brushed off during cutting of the pipe piece, the broken slag is prevented from being attached to the crack of the pipe piece, the normal operation of a cutting mechanism is influenced, the functionality of the device and the convenience of structural adjustment are improved, and the working efficiency of cutting and dismounting of the pipe piece is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a segment removal device for diameter expansion of waste tunnels and a method for using the same. Background technique [0002] In recent years, municipal pipeline tunnels, rail transit tunnels and other types of tunnels have developed rapidly in recent years. So many various types of tunnel projects determine that we will gradually transition from the current period of large-scale construction and development of tunnel projects to the restoration of various types of tunnels. In the period of maintenance, reconstruction and expansion, general tunnel projects are relatively focused on new construction.

[0002] In recent years, municipal pipeline tunnels, rail transit tunnels and other types of tunnels have developed rapidly in recent years. So many various types of tunnel projects determine that we will gradually transition from the current period of large-scale construction and development of tunnel projects to the restoration of various types of tunnels. In the period of maintenance, reconstruction and expansion, general tunnel projects are relatively focused on new construction. For the maintenance of old tunnels or tunnel expansion due to increased traffic demand, the preparation and consideration are not sufficient. Due to the limitation of tunnel section space, the longitudinal and cross-sectional layout of the tunnel and the size of the construction equipment that can be used must be fully considered. How to remove the existing tunnel lining and replace the new lining structure in the process of tunnel reconstruction and expansion is also quite difficult and challenging. ;

[0003] When the current tunnel segment is being dismantled for diameter expansion, due to the strong attachment and fixation effect between the segment and the internal structure of the tunnel, and the segment is composed of multiple structures, it is extremely difficult to dismantle, and some The segment is large in size and wide in length, and the common removal method is inefficient, which increases the difficulty and inconvenience of the operator's work; when the segment is removed, it may be necessary to grind and chisel the joints of the segments, but the gaps between different tunnels Each is inconsistent, so that the grinding and excavation structure cannot be well fitted and contacted with the segment, and during the excavation work, it is easy to generate a large amount of slag and retain it in the gap, and it is not easy to automatically remove the slag, which affects the normal operation of the cutter. At the same time, when the segment is pushed and removed later, a large amount of debris is likely to infiltrate into the device or form a blockage under the moving mechanism of the sliding device, which increases the work efficiency of the operator and reduces the practical value of the segment removal device. During the demolition work, because the bottom of the car body is not stable, the car body is easy to tilt and shake around during the demolition work, which increases the limitations of the segment demolition work and reduces the stability of the device operation
