Document Type and Number:
WIPO Patent Application WO/2023/082614
Kind Code:
A1
Abstract:
Disclosed in the present invention are a tunnel lining inspection and repair trolley and a method for repairing structural defects. The tunnel lining inspection and repair trolley comprises a trolley frame, wherein cross beams are symmetrically arranged on two sides of the bottom of the trolley frame, the cross beam is provided with a travelling power system on a bottom face thereof, and a sliding rail on a top face thereof; a plurality of foldable arc-shaped steel supporting mechanisms, telescopic arc-shaped inspection and repair supporting mechanisms and arc-shaped rail vehicle inspection and repair mechanisms that are adapted to a tunnel in shape are provided on the trolley frame; and the telescopic arc-shaped inspection and repair supporting mechanisms and the arc-shaped rail vehicle inspection and repair mechanisms are in sliding connection with the sliding rails. According to the present invention, the structure is simple, operation is flexible and convenient, and operability is high. Various components cooperate with each other, and the operation modes of the plurality of components can be flexibly switched, so that structural defects at any position of a tunnel lining can be repaired, greatly improving the operation efficiency of tunnel lining structural defect repairing, shortening the construction period, reducing financial and time investment, and having high practicability.
