Embodiment Construction

[0029] The specific implementation process of the present invention is as follows figure 1 As shown, including the following steps:

[0030] (1) Build a hydraulic model database. Create a Shapfile file in ArcGIS, including inspection wells and pipelines, set the FeatureType of the inspection well to the Point attribute, and the FeatureType of the pipeline to the Polyline attribute. Add the necessary fields to the attribute table of the created shp file. The inspection well attribute table includes the number, bottom hole elevation, well depth, ground elevation, X coordinate, and Y coordinate fields. The pipeline attribute table includes pipeline number, upstream node, downstream node , The elevation of the bottom of the upstream pipe, the elevation of the bottom of the downstream pipe, the upstream burying depth, the downstream burying depth, the pipe length, and the pipe diameter fields;

[0031] (2) Process CAD drainage pipe network drawings. CAD original drainage pipe network...

Abstract

The invention provides an automatic hydraulic model establishment method based on CAD drainage network drawing information, and belongs to the crossing field of the municipal engineering information technology and the geographic information system technology. The method starts from the hydraulic model establishment and is based on the storage situation of the CAD drainage network drawing information, complex layering does not need to be conducted on CAD engineering drawings, the manual one-by-one attribute data recording work is greatly simplified, the CAD profile diagram attribute data are converted to a GIS database in batches through TrueTable software, data can be automatically recorded in batches, the complex operation of the manual one-by-one data recording is greatly reduced, the data recording work efficiency is improved, the quality of the model data is ensured, and the quality of an established hydraulic model is improved.

Description

Technical field [0001] The invention relates to an automatic hydraulic model construction method based on CAD drainage pipe network drawing information, and belongs to the cross-field of municipal engineering information technology and geographic information system technology. Background technique [0002] The drainage pipe network system is an important urban infrastructure. It is responsible for collecting and transporting urban sewage, urban rainfall, and runoff from snowmelt. It has the dual functions of environmental protection and urban disaster reduction, and is called the "lifeline" and "bloodline" of the city. , Its role in urban planning and construction cannot be ignored. With the acceleration of domestic urbanization, the construction of urban drainage pipe network has exploded, the scale of pipe network is expanding day by day, and the pipe network data is constantly updated. The existing urban drainage pipe network operation and management methods have fallen far be...
