Embodiment 1
[0021] From figure 1 It can be seen that a BIM technology-based inverted siphon design and construction method in this embodiment includes the following steps:
[0022] Step 1. Create an inverted siphon BIM model;
[0023] Step 2. Hydraulic calculation and optimization based on the BIM model; with different flow rate values as preset parameters, calculate the pipe diameter, water level difference, head loss, pipe wall thickness, size of the grit chamber at the inlet section, downstream canal bottom elevation, and stilling basin Size, sand-carrying flow velocity, etc.; until the optimal data is selected through optimization, the optimal data is judged by head loss and sand-carrying flow velocity;
[0024] Step 3. Based on the BIM simulation of the blockage and sedimentation under normal working conditions, quicksand excess working conditions, and flow velocity exceeding working conditions, re-optimize flow velocity and other related parameters;
[0025] Step 4. Carry out co...

The invention discloses an inverted siphon design construction method based on a BIM technology, and belongs to the technical field of pipeline construction. The method comprises the following steps that step 1, establishing an inverted siphon BIM model; step 2, carrying out hydraulic calculation and optimization based on a BIM model; step 3, simulating relevant parameters such as blocking and silting conditions under normal working conditions, excessive quicksand working conditions and flow velocity over-limit working conditions on the basis of BIM, and re-optimizing the flow velocity and thelike; step 4, performing construction simulation based on the BIM model, and performing visual disclosure; and step 5, performing construction management based on the BIM technology, inputting an emergency problem into the BIM model in construction, and performing re-optimization until the problem is solved. According to the method, based on the BIM three-dimensional visualization model, hydraulic calculation and optimization are carried out, and the problems that calculation is complex, errors are likely to happen, design is unreasonable, water is stored, blocking is caused, and abrasion iscaused in design, construction and operation and maintenance are avoided.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, and more specifically, relates to a design and construction method of an inverted siphon based on BIM technology. Background technique [0002] More and more urban pipelines cross rivers, etc., requiring the design of inverted siphon pipelines. However, the design and construction of inverted siphons are more traditional methods. The calculations in the design and construction are relatively complicated, and it is easy to make calculation errors and unreasonable designs. As a result, the inverted siphon pipes often have problems such as water retention, blockage, and wear. [0003] The development of BIM (Building Information Modeling) technology can provide technical support for refined design and construction of inverted siphon engineering. Contents of the invention [0004] 1. The technical problem to be solved by the invention [0005] Aiming at the defects and deficiencies ...
