Problems solved by technology

In order to avoid the risk of missed detection of high-speed rail off-line structures, the risk detection of high-speed rail off-line structures not only needs to collect data continuously along the survey line, but also the distance between geophones and side lines is very small, generally less than 0.5m, so the geophone setting , Recycling and moving cost a lot of manpower and time, which seriously affects the operation efficiency
In particular, how to install the geophone on the high-speed rail track slab is a difficult point, and it will be serious if the track slab is occupied for a long time, which will affect the high-speed rail traffic and safety

Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but It is not intended to limit the scope of the invention.

[0023] Such as figure 1 A device for non-destructive testing of offline structures of high-speed railways shown includes: m transverse belts 100, n longitudinal belts 200, m×n wave detectors 300, and a recorder (not shown).

[0024] Specifically, m transverse strips 100 are arranged at intervals.

[0025] The n longitudinal strips 200 are arranged at intervals. Each longitudinal strip 200 intersects each transverse strip 100 to form m×n intersection points.

[0026] Each wave detector 300 is correspondingly arranged on each intersection point.

[0027] The ...

Abstract

The invention discloses an apparatus for nondestructive detection of the underline structure of a high speed railway. The apparatus comprises: an m column * n row sensor array formed by using m*n sensors, wherein every wave detector is correspondingly arranged in every intersection; and a recorder respectively connected with the m*n wave detectors, wherein m and n are natural numbers being more than or equal to 2. The apparatus for nondestructive detection of the underline structure of a high speed railway connects the wave detectors through using transverse bands and longitudinal bands to form a movable integral body, so the problems of influences of great manpower and long time consumed in the arrangement, recovery and movement process of the wave detectors on the working efficiency in the prior art and influences of long-time occupation of a track board on the traffic and the safety of the high-speed rail are solved.

Description

technical field [0001] The invention relates to the field of concrete structure detection, in particular to a device for non-destructive detection of offline structures of high-speed railways. Background technique [0002] In my country, high-speed railway is an indispensable part of modern transportation, and it is of great significance for shortening the distance between cities and promoting coordinated regional development. Compared with traditional railway transportation methods, high-speed rail has the advantages of fast transportation speed, large transportation capacity, low pollution, safety and punctuality. In the fast and safe operation of high-speed railways, its multi-layer off-line structure (mainly including the structural layers under the ballastless track and the road basic body, etc.) is the basic hardware structure that directly carries high-speed trains and ensures the safe running of high-density, high-speed trains . In recent years, with the speed incr...
