Description
Technical field
The present invention relates to the non-excavating underground pipe line field, relate in particular to a kind of method for establishing three-dimensional visual non-excavating underground pipe line GIS.
Background technology
Underground utilities are the lifelines in city; Because historical reasons; Present City Buried Pipeline data; Attribute card, statistical form with as-constructed drawing and pipeline write down expression, and this manual way to manage does not catch up with the demand of urban duct building cause development far away, are difficult to satisfy the requirement of modernized underground pipe network management.In recent years, trenchless pipelaying technology is with its distinctive advance, adaptability, widespread use in city underground engineering and underground utilities are built.Shanghai City takes the lead in adopting at home trenchless technology to implement large-scale urban duct construction project, and in 2007 first half of the year, pipe engineering non-excavating construction amount accounts for 50% of whole pipeline construction item number.
Adopt pipeline that non-excavation technology lays buried depth big (2～15m) than other underground pipeline; Shanghai Urban above and below ground cable gathers in addition, and is very big to the equipment interference to control, makes construction time institute's depth measurement degree error increase.The locus accurate location of this type pipeline and as-constructed drawing data error be big (10～20%).Adopt conventional detecting devices can't (especially small-bore pipeline) accurately be measured in the pipeline space position that non-digging mode is laid.This brings very big obstacle for planning, maintenance, the management of city subterranean resource and the development of non-excavation cause of City Buried Pipeline.In recent years, because non-excavation pipeline data is inaccurate, frequently cause underground electric power, coal gas, communication pipeline impaired, therefore, research three-dimensional visual non-excavating underground pipe network GIS management system is extremely urgent.
In the prior art, the initial stage nineties is to mid-term, along with GIS software is widely used in some industries, so also be applied to the management of pipeline spatial information and attribute information rapidly.China uses external GIS platform (ARCINF0, INTERGRAPH) in succession the beginning of the nineties, have in addition explore exploitation pipeline information management system with AUTOCAD.Meanwhile homemade GIS platform is succeeded in developing (like MAPGIS), has also developed the underground pipeline information management system with homemade GIS platform, and the development of City Buried Pipeline information management system gets into a new stage thus.
But, have only the underground pipeline information of shallow embedding in the above-mentioned domestic and international underground pipeline information management system, structure and basic data all are two-dimentional, can only be applied to conventional, the pipeline that adopts digging mode to bury underground.
