Abstract

The invention discloses an auxiliary tool used for tunnel defect investigation. The acquirement of accurate and comprehensive tunnel structure defect information is significant during tunnel maintenance work. The existing tunnel defect investigation work has many difficulties. For example: the efficient measurement of defect information more than 2 m above the ground is difficult to realize by people; although a lift truck expands the investigation range, the lift truck has low efficiency, poor safety and great influence on traffic insurance, and investigation is still difficult to cover all regions in the tunnel structure; and in addition, the positions, the shapes and the degrees of defects are manually marked on a paper tunnel spreading drawing during the investigation process, so that the defect information is distorted or seriously lost. With the auxiliary tool, the quick and efficient collection of defect information can be realized to directly form electronic information, and the auxiliary tool has the characteristics of convenience for carrying, flexible use, high information accuracy, high investigation efficiency, high investigation safety and the like.

Description

technical field [0001] The invention belongs to the field of tunnel maintenance of highways, railways, water conservancy, rail transit, etc., and in particular relates to the technical field of tunnel disease investigation. Background technique [0002] With the rapid development of my country's infrastructure construction, the number of tunnels has increased rapidly in the past 30 years. With the increase of tunnel operation time, almost all tunnel structures are exposed to varying degrees of damage, mainly including the following categories: leakage, lining corrosion, lining crack damage, tunnel freezing damage, etc., which affect the safety of operation. In order to grasp the occurrence and development of tunnel diseases in a timely manner, the tunnel operation maintenance and management departments usually adopt regular or special disease investigation activities to collect disease information of tunnel structures, and make maintenance decisions based on the collected tu...
