Secondary design construction method for low-pressure boiler small pipeline on the basis of BIM (Building Information Modeling) technology

Abstract

The invention discloses a secondary design construction method for a low-pressure boiler small pipeline on the basis of a BIM (Building Information Modeling) technology. The method comprises the following steps that: establishing the three-dimensional stereo models of all pipeline and equipment, and importing pipeline and equipment model and position data to carry out the collision detection of a three-dimensional stereo model graph; designing the starting point and the end point of the small pipeline, establishing the position data, and carrying out the collision detection of the three-dimensional stereo model graph on electric and thermal control equipment; according to a material bill provided by the BIM software technology, carrying out statistics on the type, the amount and the length information of each component of the boiler small pipeline; installing a small pipeline hanging bracket, and baiting and bending the small pipeline on the ground; and carrying out collision detection on an important position and a field condition, and guaranteeing a construction plan. According to the construction plan, construction simulation and progress simulation are carried out, each professional collision problem is coordinated to generate coordinated data to determine a reasonable construction scheme and construction period, a construction period is reduced in general, a great quantity of artificial, material, mechanical and equipment costs can be saved, and economic benefit and social benefit are obvious.

Description

[0001] Technical field: [0002] The invention relates to a pipeline construction method, in particular to a secondary design and construction method for medium and low pressure boiler small pipelines based on BIM technology. [0003] Background technique: [0004] There are a large number of small pipes below DN80 in the boiler pipes of thermal power units. The characteristics of small pipes are that there are many types of pipeline specifications and models, and the working conditions and working environments are different. In small pipelines, the pipe diameters of dosing and sampling, drainage and steam release pipes are generally smaller than DN80. At present, the design institute generally only issues system diagrams but not layout drawings for small pipelines below DN80 in thermal power units, and only gives the starting point and end point. It is necessary to consult the drawings and determine the location and direction of the small pipelines according to the site condit...

Problems solved by technology

If the second on-site design of all parties is improper, the communication is not in place, and a little carelessness will occur, there will be a collision between professionals

It is very difficult to modify the direction and position of the constructed pipeline, which may cause a large detour and greatly increase the labor and material consumption

If the arrangement is not proper, it will affect the appearance and function at least, and it will affect the operation economy and safety

In addition, the uncertainty of on-site design, the planned procurement of materials, and the determination of the entry time all bring certain difficulties, which may cause delays or waste of materials

[0005] At present, my country's construction progress management mainly uses P6, Microsoft project and other engineering management software to manage the construction progress plan, and the progress management mode only stays on the two-dimensional plane. It is difficult to achieve comprehensive, coordinated and refined management
