A. Project background

The Gahaishan Reservoir in Kulun Banner, Tongliao City, Inner Mongolia is a key water conservancy project in the autonomous region, with a total reservoir capacity exceeding3300 × ten thousand cubic meters, undertaking important tasks such as urban water supply, irrigation and flood control. In order to ensure the fire safety of key buildings such as the reservoir management area and pumping station buildings, the project requires the construction of a highly reliable fire water supply system that is adapted to the severe cold climate in the north. After comprehensive demonstration, the underground box pump integrated fire pump station solution was adopted.

B. Solutions and core advantages

The fire pump station used in this project is fully underground and integrated in design, which effectively solves the problems of traditional fire pools and pump rooms covering a large area, long construction period, and difficulty in thermal insulation and antifreeze. 

Core advantages:

1、Intensive and efficient, saving land:Integrating the water tank and pump room underground does not occupy valuable ground space and is coordinated with the overall planning of the reservoir.

2、Quick assembly, guaranteed construction period:The modular construction model of factory prefabrication and on-site overall hoisting has greatly shortened the construction period and ensured the progress of the main reservoir project.

3、Safe and stable, intelligent operation and maintenance:The equipment has excellent anti-corrosion, anti-seepage and anti-floating properties. The intelligent control system can realize automatic inspection, remote monitoring and fault warning, meeting the high standard requirements of unattended operation.

C. Main technical parameters and configuration

This pumping station is designed in strict compliance with national fire protection regulations. The core parameters are as follows:

fire water tank    Dimensions:7m×12m×3.5m(Effective volume is approx.280m³). The board adoptsBDFComposite stainless steel plate combines the corrosion resistance of stainless steel with the strength of galvanized steel and has a long service life.

Pump room structure    Dimensions:7m×5m×3.5m, it is galvanized sheet and has high cost performance.

fire pump unit    Equipped with a complete fire hydrant skid-mounted pump unit, including main pump, backup pump and supporting control valve pipelines, it is highly integrated and can be started quickly to ensure continuous and sufficient pressure supply of fire extinguishing water.

Voltage stabilization system    Equipped with a fire-fighting voltage stabilizing unit to maintain the normal pressure of the pipe network, ensure timely response to water pressure in the early stages of a fire, and avoid system overpressure.

control system    Intelligent electric control cabinet, equipped with dual power automatic switching, automatic/Manual start and stop pump, real-time data monitoring and remote IoT monitoring functions.

D. Implementation value

The completion of the underground box-pump integrated fire pump station has significantly saved land and construction costs. Its intelligent features have reduced the human and material investment in long-term operation and maintenance management. At the same time, it has provided a solid fire safety guarantee for the Gahaishan Reservoir project. This project has become a successful case for the application of new integrated fire-fighting equipment in water conservancy projects in severe cold areas in the north, providing valuable experience for similar projects.
