Compared with the prior art, the pipe prefabrication method has the advantages that the prefabrication accuracy can be improved, the field working efficiency is improved and the like.
Description
Technical field
The present invention relates to a kind of pipe prefabrication process technology, especially relate to a kind of pipe prefabrication method based on BIM.
Background technology
The prefabricated processing that has utilized the BIM technology to reach pipeline is at present abroad installed with on-the-spot.China is just at the early-stage in this respect, in some national major projects, also began to carry out this technology in recent years, but it is also very big that prefabricated degree and industries such as civil engineering, steel construction, glass curtain wall are compared gap, particularly the pipeline welding technology in the electromechanical installation does not have important breakthrough in recent years yet, still rests on the operator scheme stage that site welding is made.
Pipework is many owing to itself possessing caliber, the material complexity, wall thickness series does not wait, the characteristics that the welding engineering amount is big, in work progress, then be subjected to material supplies, equipment is handed over peace, weather conditions, many restraining factors influences such as site work face, welding capacity was big during particularly pipeline connected, traditional engineering design mode underground pipelines is arranged also accurate inadequately, thereby cause its prefabricated degree lower, at present domestic still many dependence site operation mounting meanss are main, this method at first needs to arrange at the scene a large amount of operators, and this daily management to the scene has brought certain pressure.Secondly, on-the-spot environment more complicated, the working interface confusion, workman's work efficiency is lower.Moreover in-situ processing must much be got angry a little, and this has increased on-the-spot potential safety hazard undoubtedly.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of pipe prefabrication method based on BIM that improves prefabricated machining accuracy, improves work on the spot efficient for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of pipe prefabrication method based on BIM, this method may further comprise the steps:
1) three-dimensional modeling: two-dimensional design figure is converted into corresponding BIM three-dimensional model;
2) collision detection: adopting and based on the collision detection algorithm of pipeline model three-dimensional model is carried out collision detection, is zero collision until the collision result, exports final three-dimensional model;
3) prefabricated processing pre-service: according to assembling sequence all pipeline sections in the three-dimensional model are numbered, export and print prefabricated manuscript and numbering result;
4) prefabricated processing: make pipe prefabrication spare according to prefabricated manuscript and numbering result.
Described collision detection algorithm based on the pipeline model is specially:
21) each Professional Model in the derivation three-dimensional model comprises foundation construction model and electromechanical model;
22) each Professional Model is carried out overlap-add procedure, it is superimposed as comprehensive pipeline model and collides;
23) synchronous recording and demonstration collision result;
24) judge whether the collision result is " zero " collision, if, then withdraw from, if not, then three-dimensional model is adjusted, return step 21).
Described collision result comprises crash type and position of collision information.
Numbering result in the described step 3) comprises pipeline section numbering and each length of pipe section.
Prefabricated manuscript comprises fabricate block and fragment number information, pipeline material parts list information and each pipeline section dimension information of pipeline in the described step 3).
Compared with prior art, the present invention has the following advantages:
1, by utilizing the basic model of accurate BIM model as prefabricated processing design, when improving prefabricated machining accuracy, reduced on-the-spot mapping operations amount, the quality of constructing for accelerating construction progress, raising provides strong guarantee.
Consider from the angle of green construction that 2, the prefabricated of batch production can reduce on-the-spot cutting, the operation of welding in a large number, reduced carbon dioxide isothermal chamber gas purging, protected environment.Consider that from the angle of cost the prefabricated of batch production can effectively reduce on-the-spot labour's configuration, reduces labor cost.Consider that from the angle of site operation safety prefabricated the getting angry a little of having reduced the scene of batch production reduced the incidence of fire.Consider that from the angle of work efficiency the prefabricated of batch production is placed on a large amount of cuttings, weld job in the factory and finishes, the execute-in-place workman only needs the duct segments assembling is got final product, and has made full use of the existing working time, has improved on-the-spot work efficiency greatly.
3, by with the combining of BIM technology, be implemented in and finish comprehensive adjustment before unit in charge of construction marches into the arena, required pipeline section shifts to an earlier date early-stage preparations such as completion of processing, scheme preview, in accurately construction, accurately plan, promote and bringing into play enormous function aspect the benefit.
