Description

System segment inside tunnel being positioned and automatically detects

Technical field

The present invention relates to a kind of Tunnel testing system, particularly relate to a kind of detection system of segment inside tunnel, be applied to tunnel failure detection field.

Background technology

Shield duct piece is the main mounting structure of shield-tunneling construction, is the outermost layer barrier in tunnel, carries the effect of opposing earth pressure, groundwater pressure and some special loads.Therefore, detect that the state of section of jurisdiction is very important for tunnel safety in time, and current detection means mainly contains following two hang-ups:

On the one hand, the height in general tunnel is 6 ~ 7 meters, and on such section of jurisdiction, the installation site of detection chip is also just higher, and traditional handheld device is difficult to the detection reaching this height.And manual detection labour intensity is large, and efficiency is low.

On the other hand, in Tunnel testing, orientation problem is also a difficult point.For tens the kms even tunnel of tens kms, it is obviously not too desirable for being located by handmarking.Because tunnel environment is single, the feature of section of jurisdiction is also about the same, and in a long tunnel, the positioning error of several meters also will can not be got rid of by causing trouble in time, brings potential safety hazard.

BuildingInformationModeling, is called for short BIM, i.e. BIM.The real information that BIM can be had by numerical information analogue simulation buildings, not only comprises 3 dimensional coil geometry information, also comprises other a large amount of information, as the material of building element, weight, price and progress etc.BIM is integrated with the data model of the various relevant information of construction-engineering project, it is the detailed expression to this project item related information, but how to make a large amount of section of jurisdiction Site Detection information and the BIM Database relation one to one in tunnel, become the difficult problem of BIM in actual application.Which greatly limits the powerful software data analysis of BIM and management function, affect the potential safety hazard that Timeliness coverage tunnel exists, the needs detected in real engineering can not be adapted to.
