Overview

The standard for the procurement of intelligent interception wells in Hubei province is the hydraulic downward opening weir gate, which is an intelligent device that uses hydraulic drive technology to achieve the opening and closing of the weir gate. The core principle is to use the telescopic movement of hydraulic cylinders to drive the weir plate to move up and down, thereby achieving precise control of water flow. Compared with traditional mechanical barrier gates, hydraulic lower opening barrier gates have significant advantages such as fast response speed, high control accuracy, and smooth operation. In practical applications, this device can automatically adjust the opening height of the dam gate based on water level sensors or remote control signals, achieving intelligent management of rainwater and sewage diversion or flood control and drainage. For example, in the early stages of rainfall, the barrier gate can remain relatively stable

Product Details

In recent years, Hubei Province has continuously increased investment in the construction of urban flood control and drainage systems. As a key facility for rainwater and sewage diversion and flood control scheduling, the procurement standards of intelligent interception wells directly affect the level of intelligence of urban infrastructure. According to the Hubei Provincial Government Procurement Network and Jingzhou Municipal Government Information Disclosure, the province has completed multiple rounds of centralized procurement of intelligent interception well equipment in 2025, and the relevant technical specifications have formed a systematic framework. This article will combine procurement documents with industry practices to provide a detailed analysis of the current procurement standard system for intelligent interception well equipment in Hubei Province.

1、 Core technical parameter requirements 1 The procurement standard for sensing and monitoring systems clearly requires the installation of multi parameter integrated sensors, which need to monitor real-time data such as water level (accuracy ± 1cm), flow velocity (error ≤ 3%), water quality (COD/ammonia nitrogen online detection), and have sediment deposition warning function. In the Jingzhou 2025 Smart Drainage Project, it is emphasized that sensors must pass IP68 waterproof certification, and the data collection frequency can be adjusted within the range of 1-30 minutes per time.

2. The performance equipment of the control system must be equipped with a dual-mode control module that supports remote platform commands and local automatic logic judgment. According to the bidding documents, the Wuhan Donghu High tech Zone project requires a control response time of ≤ 5 seconds, a repeat positioning accuracy of ± 2mm for gate opening and closing, and a power-off memory function. It is worth noting that the standards updated in the third quarter of 2025 have added AI algorithm requirements to support linkage adjustment of rainfall forecasting.

3. Hubei Intelligent Interception Well Procurement Standard Hydraulic downward opening barrier gate is an intelligent device that uses hydraulic drive technology to achieve barrier gate opening and closing. The core principle is to use the telescopic movement of hydraulic cylinders to drive the weir plate to move up and down, thereby achieving precise control of water flow. Compared with traditional mechanical barrier gates, hydraulic lower opening barrier gates have significant advantages such as fast response speed, high control accuracy, and smooth operation. In practical applications, this device can automatically adjust the opening height of the dam gate based on water level sensors or remote control signals, achieving intelligent management of rainwater and sewage diversion or flood control and drainage. For example, in the early stages of rainfall, the barrier gate can maintain a small opening to divert the initial rainwater to the sewage pipe network for treatment; When the rainfall increases, the barrier gate can automatically open to ensure rapid drainage of rainwater and avoid waterlogging. Hydraulic swing gates are usually made of stainless steel or high-strength composite materials, which have excellent corrosion resistance and structural strength, and can adapt to long-term stable operation under various harsh environmental conditions.

Hubei Intelligent Interception Well Procurement Standard Flexible flow interception equipment represents another innovative flow interception technology route. This type of equipment is usually made of polymer composite materials or rubber materials, which have good flexibility and sealing performance. The working principle of flexible interception equipment is to achieve flexible control of water flow by inflating or mechanically changing the shape and position of the interception fluid. Compared with rigid interception devices, flexible equipment has the advantages of easy installation, strong adaptability, and good sealing effect. In scenarios such as pipeline interception and inspection well interception, flexible interception equipment can tightly adhere to the pipe wall, effectively preventing sewage from flowing back or overflowing. Especially in the renovation of old urban pipeline networks, flexible flow interception equipment is highly favored due to its strong adaptability to pipeline shapes. Some flexible interception systems also integrate intelligent monitoring functions, which can provide real-time feedback on interception status and equipment operating parameters, providing decision support for management personnel.

The control system of intelligent interception well equipment is the key to ensuring its efficient operation. Modern intelligent interception systems typically use PLC (Programmable Logic Controller) or IoT technology to achieve remote monitoring and automated operation of equipment. By collecting data through monitoring devices such as water level sensors, flow meters, and rain gauges, the control system can analyze the operating status of the drainage system in real time and automatically adjust the operating parameters of the interception equipment accordingly. For example, before the rainy season, the system can adjust the closure strategy in advance according to the weather forecast data; In the event of sudden heavy rainfall, the system can respond quickly, optimize the coordinated operation of various interception points, and maximize the overall efficiency of the drainage system. In addition, the intelligent control system also has fault diagnosis and warning functions, which can timely detect equipment abnormalities and notify maintenance personnel, greatly improving the reliability and maintenance efficiency of the system.

2、 Structural Design and Material Standards 1 The mechanical structure specification for well body diameter is divided into three levels of standards: DN800, DN1000, and DN1200, with a wall thickness of not less than 12mm made of ductile iron or 304 stainless steel. In the bidding for the Yichang project in 2025, it is specifically stated that the design of the anti silt groove must meet a 45 ° inclination angle, and the wear resistance coefficient of the gate guide rail must reach HB250 or above.

2. The overall anti-corrosion and sealing performance requirements are C5 level anti-corrosion treatment, and key components are made of 316L stainless steel. The sealing system must pass a 72 hour 1.5 times pressure test, and the service life of the rotating shaft seal should not be less than 100000 times of opening and closing. The technical specifications of Wuhan Water Bureau have added requirements for the selection of microplastic filtration devices.

3、 Intelligent functional indicator 1 The procurement document for the decision support system requires the equipment to have a built-in hydraulic model that can automatically optimize the interception strategy based on historical data. The 2025 project in Huangshi City will include digital twin linkage as a scoring item, requiring equipment to support 3D working condition simulation.

2. The security protection mechanism mandates the installation of dual redundant power modules, and the backup power supply must maintain 72 hours of operation. In terms of network security, it is necessary to comply with the Level 3 requirements of Equal Protection 2.0 and have data encryption and firewall functions. A project case in Shiyan City shows that the response time for illegal intrusion alarms has been compressed to 30 seconds.

4、 Operation and maintenance guarantee system 1 The standard contract for warranty and service terms stipulates that the warranty period for the entire machine shall not be less than 5 years, and key components (such as servo motors) shall be provided with a 10-year extended warranty. Suppliers are required to establish a 4-hour response service network within Hubei Province and provide dedicated maintenance vehicles.
