Description

Technical Field

[0001] The present invention relates to the technical field of construction of building water supply and drainage systems, and specifically to an assembly method for basic water supply and drainage facilities in industrial parks. Background Art

[0002] The water supply and drainage system is the "blood vessel" of the park infrastructure and directly affects the production efficiency of enterprises. The basic water supply and drainage facilities in industrial parks can provide stable and safe industrial water and domestic drinking water for the enterprises in the park. By separating rainwater and sewage through a rainwater-sewage diversion system, supporting sewage treatment plants and reclaimed water facilities, the industrial wastewater can be discharged up to standard or recycled, preventing environmental pollution.

[0003] In the prior art, the construction plans for basic water supply and drainage facilities in industrial parks have problems such as low efficiency and unstable quality during the construction stage. Especially in complex environments such as industrial parks, the construction difficulty is greater. Moreover, the traditional plan uses galvanized pipes, which need to be maintained or replaced regularly, resulting in high long-term maintenance costs. And the on-site welding process is easily affected by environmental temperature and humidity, with large quality fluctuations and unable to meet high-precision requirements. Especially for the facilities required for anti-corrosion drainage in chemical industrial parks, it is even difficult to meet the long-term use requirements, and the system fault troubleshooting efficiency lacking data support is low. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an assembly method for basic water supply and drainage facilities in industrial parks to solve the problems raised in the above background art. The present invention can significantly improve the construction efficiency and quality of water supply and drainage facilities, reduce construction risks, and has broad application prospects and market value. It realizes the efficient assembly and long-term operation and maintenance of the water supply and drainage system in industrial parks.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: An assembly method for basic water supply and drainage facilities in industrial parks includes the following steps:

[0006] Step 1: Select pipes, optimize the pretreatment and cutting technology of materials, verify the compatibility of pipes, perform cutting treatment on pipes, and control the finished product parameters;

[0007] Step 2: Simulate the water flow state in the pipe network through computational fluid dynamics software, set the water flow parameters, where the water flow parameters include flow velocity, pressure distribution, and turbulence intensity, identify high-resistance areas or cavitation risk points, and regulate the pipeline orientation, pipe diameter configuration, and valve position;

[0008] Step 3: Monitor the key construction nodes in real time, use ultrasonic flow meters and pressure sensors to monitor the pipeline pressure bearing and leakage, and detect internal defects of the hot melt joints through an infrared thermal imager;

[0009] Step 4: Generate an electronic report based on construction quality, record construction time, environmental parameters, and test data, achieve full-cycle traceability, detect abnormal data, automatically trigger warnings, and link to maintenance responses.

[0010] Further, the pipes in Step 1 include PVC pipes. Before construction, a material compatibility test is carried out to verify the compatibility of the adhesive with the pipes. A double-blade cutting machine is used, and the perpendicularity deviation of the cut is ≤1°. After cutting, a chamfering tool is used to process a 15° bevel.

[0011] Further, the PVC pipes use low-VOC solvent-based glue, control the temperature at 20°C for curing for 8 minutes, quickly insert and rotate half a turn after applying the glue to ensure uniform distribution of the colloid and form a continuous glue ring.

[0012] Further, the pipes in Step 1 include PP-R pipes. An electric rotary cutting machine is used, with a cutting accuracy of ±0.5 mm and a blade rotation speed of 3000 rpm to cut the PP-R pipes. The welding depth is marked with a marker pen at the insertion end of the pipe, and the welding depth is 1.1 times the pipe diameter.

[0013] Further, control the heating temperature at 200°C - 260°C, the heating time at 40 seconds, and the stabilization time at 60 seconds, and conduct a working pressure test. During the test, the pressure of the PP-R pipe ≥1.0 MPa, and the pressure drop ≤0.02 MPa after stabilizing for 1 hour.

[0014] Further, in Step 2, it also includes selecting and constructing physical models through fluid dynamics simulation software, using Ansys SpaceClaim to extract pipeline geometric data in combination with the BIM model, and automatically generating a parametric model library. The pipeline geometric data includes pipe diameter and elbow curvature radius. The selected adaptation types of the physical models include steady-state flow, transient analysis, and multiphase flow scenarios.

[0015] Further, use boundary layer grids for key areas, with the number of layers ≥5, a growth rate of 1.2, and the global grid size controlled within 1 / 10 of the pipe diameter. The key areas include valves and pump interfaces. Use a CNN network to replace time-consuming CFD calculations to achieve second-level design scheme evaluation.

[0016] Further, in Step 3, deploy distributed fiber optic sensors, arrange a measuring point every 5 meters along the pipeline, identify leaks at the 0.1 mm level through the phase change of the optical signal, and the positioning accuracy is ±0.5 m; arrange vibration, temperature, and pH value triple sensors to track the scope of pipeline corrosion and external force damage areas, and set the vibration threshold > 3.5 mm / s 2 Alarm.

[0017] Furthermore, a drone swarm equipped with hyperspectral cameras scans and identifies abnormal heat sources in drainage pipes at night, pre-generates inspection routes based on the BIM model, compares the actual point cloud data in real time, and dynamically adjusts the scanning and identification trajectory.

[0018] Furthermore, construction records, monitoring data, and maintenance logs are stored on the blockchain as evidence, and a three-dimensional pipe network model is constructed based on BIM+GIS to map the physical system status in real time. A graph library of fault cases is built, and combined with historical data and real-time parameters, the fault probability for the next 48 hours is calculated.

[0019] Advantages of the present invention:

[0020] 1. The assembly method of the basic water supply and drainage facilities in this industrial park uses new plastic or composite pipes, which have significantly better corrosion resistance and impact resistance than traditional galvanized steel pipes or cast iron pipes. The service life can reach more than 50 years, reducing leakage problems caused by rust. And it supports recycling; the rainwater recycling and greywater treatment systems can reduce the water consumption in the park.

[0021] 2. The assembly method of the basic water supply and drainage facilities in this industrial park uses prefabricated pipe modules and is connected through factory prefabricated flange joint pipe sections, which can effectively reduce the amount of on-site cutting and welding operations and shorten the construction period.

[0022] 3. The assembly method of the basic water supply and drainage facilities in this industrial park optimizes the pipe network design through CFD simulation, reduces the risk of water hammer effect, and monitors leakage points in real time based on the Internet of Things, reducing the system failure rate and avoiding problems such as hydraulic imbalance or local blockage that are prone to occur in traditional designs that rely on experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic structural diagram of the outer shape of an assembly method for basic water supply and drainage facilities in an industrial park according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0024] In order to make the technical means, creative features, achieved purposes, and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figure 1 , the present invention provides the following technical solutions: An assembly method for basic water supply and drainage facilities in an industrial park, including the following steps:

[0026] Step 1: Select pipes, optimize the material pretreatment and cutting technology, verify the compatibility of the pipes, cut the pipes, and control the finished product parameters.

[0027] This embodiment provides PVC pipes for use as drainage pipes. A material compatibility test is performed before construction to verify the compatibility of the adhesive and the pipe. A double-blade cutting machine is used, and the verticality deviation of the cut is ≤1°. After cutting, the chamferer processes the 15° groove. Low-VOC solvent-based glue is used for the PVC pipe, and the temperature is controlled at 20°C for curing for 8 minutes. After applying the glue, the pipe is quickly inserted and rotated half a circle to ensure that the colloid is evenly distributed to form a continuous rubber ring.

[0028] This embodiment also provides a PP-R pipe for use as a drainage pipe. An electric rotary cutter is used with a cutting accuracy of ±0.5mm and a blade speed of 3000rpm to cut the PP-R pipe. The insertion end of the pipe is marked with a marking pen to mark the welding depth. The welding depth is 1.1 times the pipe diameter. The heating temperature is 200°C to 260°C, the heating time is 40 seconds, the stabilization time is 60 seconds, and the working pressure test is performed. During the pressure test, the PP-R pipe is ≥1.0MPa, and the pressure drop is ≤0.02Mpa after stabilizing for 1 hour.

[0029] In this embodiment, a transition connection scheme using different materials is also provided, including flange conversion: using PP-R flange to connect with PVC flange, adding EPDM rubber gasket in the middle, and controlling the bolt preload to 20-30N·m. And using a flexible joint and a dual-material flexible joint.

[0030] When the ambient temperature is less than 5°C, use a hot air gun to heat the PP-R pipe locally and preheat it to above 15°C. The PVC adhesive needs to be stored in a warm place.

[0031] Step 2: Use computational fluid dynamics software to simulate the water flow state in the pipe network, set the water flow parameters, including flow velocity, pressure distribution, turbulence intensity, identify high resistance areas or cavitation risk points, and adjust the pipeline direction, pipe diameter configuration and valve position.

[0032] Through the physical model selection and components of the fluid dynamics simulation software, Ansys SpaceClaim is used in combination with the BIM model to extract the pipeline geometry data, and automatically generate a parametric model library. The pipeline geometry data includes pipe diameter and elbow curvature radius; the physical model selection and adaptation types include steady-state flow, transient analysis, and multiphase flow scenarios;

[0033] Boundary layer grids are used for key areas, with the number of layers ≥ 5 and a growth rate of 1.2. The global grid size is controlled at 1 / 10 of the pipe diameter. The key areas include valves and pump interfaces. CNN networks are used to replace time-consuming CFD calculations to achieve design scheme evaluation in seconds, with a control error of <3%.

[0034] According to the flow velocity distribution (recommended 1.0 - 2.5 m / s), the original DN150 pipe is segmented and changed to a DN125 + DN180 combination. A regulating valve (such as a V-type ball valve) is added in the flow velocity mutation area to reduce the local head loss.

[0035] Step 3: Monitor the construction key nodes in real time. Use an ultrasonic flowmeter and a pressure sensor to monitor the pipeline pressure bearing and leakage. Detect internal defects of the hot melt joint through an infrared thermal imager. Deploy distributed fiber optic sensors, with one measuring point arranged every 5 meters along the pipeline. Identify leaks at the 0.1 mm level through the phase change of the optical signal, and the positioning accuracy is ±0.5 m. Install a vibration, temperature, and pH value triple sensor to track the scope of pipeline corrosion and external force damage areas, and set the vibration threshold > 3.5 mm / s 2 Alarm;

[0036] A group of drones equipped with hyperspectral cameras scan at night to identify abnormal heat sources in the drainage pipes. Based on the BIM model, the inspection routes are pre-generated, and the actual point cloud data is compared in real time to dynamically adjust the scanning and identification trajectory.

[0037] Step 4: Generate an electronic report based on the construction quality, record the construction time, environmental parameters, and detection data, achieve full-cycle traceability, detect abnormal data and automatically trigger an early warning, and link to the maintenance response. Chain the construction records, monitoring data, and maintenance logs for evidence storage, and build a three-dimensional pipe network model based on BIM + GIS to map the physical system status in real time, build a graph library of fault cases, and calculate the fault probability for the next 48 hours by combining historical data and real-time parameters.

[0038] And build an intelligent spare parts warehouse. Based on the monitoring data, predict the lifespan of spare parts and automatically call the spare parts in the warehouse. The call condition is set as the component usage time limit < 10%.

[0039] Connect the data collected above to the urban-level CIM platform to share the drainage volume and water quality data of the park in real time.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0041] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
