Method of automatically arranging and counting accessories in pipe network design

Abstract

The invention discloses a method of automatically arranging and counting accessories in pipe network design. The method includes a joint arrangement and counting method, which includes: S11, numberingnodes of a head end and a tail end of each pipeline in the pipe network, and carrying out labeling in a graph, S12, enabling pipe diameters to correspond to node numbers of the head end and the tailend of the pipeline, S13, traversing each pipeline in the pipe network, and judging whether each node of the head end and the tail end of the pipeline is an elbow, a three-way or a four-way, and S14,judging connection pipe diameters, then defining specifications and the accessories corresponding to all the elbows, the three-ways and the four-ways; and also includes a valve well arrangement and counting method, which includes: S21, extracting elevations along the pipeline, S22, generating a profile graph according to a pipeline plane arrangement graph and the extracted elevations along the pipeline, and S23, extracting highest points and lowest points in predetermined ranges in the profile graph, and respectively arranging exhaust valve wells and emptying valve wells. The method of automatically arranging and counting the accessories can improve work efficiency of pipe piece arrangement and counting, and reduce manual job quantity.

Description

technical field [0001] The invention relates to a method for automatically arranging statistical fittings in pipe network design, and belongs to the technical field of pipe network design. Background technique [0002] The fittings in the pipe network play the roles of connection, control, direction change, diversion, sealing, support, etc. in the piping system. The types of pipes and connection methods are different, and the selected fittings are also different. Pipe network design is generally completed in drawing design software such as AUTOCAD. In traditional pipe network design, the estimation method is generally used when counting the number of fittings, that is, 10% to 15% of the pipe network investment is included, which results in The statistics of engineering quantities are not accurate; in addition, there is a method of manually defining in the drawing design software, and then automatically counting through the drawing design software. This method has a huge work...

Pipe network design is generally completed in drawing design software such as AUTOCAD. Traditional pipe network design generally adopts an estimation method when counting the number of accessories, that is, 10% to 15% of the pipe network investment is included, which results in The statistics of engineering quantities are not accurate; in addition, there is a method of manually defining in the drawing design software, and then automatically counting through the drawing design software. This method has a huge workload for long-distance water distribution networks. Generally thousands, manual definition is time-consuming and labor-intensive
