As a core supplier of hose pumps that China Railway Engineering Equipment Group Co., Ltd. has long trusted, today the CREG Group delegation visited our company and visited the modern workshop of our factory, starting an in-depth dialogue on the technical strength of hose pumps and infrastructure supply guarantees. In response to the special needs of China Railway Engineering Equipment Group Co., Ltd., Gaode Equipment has developed high-temperature-resistant industrial hose pumps, concrete linings and convey pea-gravel shotcrete pump, as well as belt conveyors and grouting equipment, among others. These products have been successfully applied to projects under extreme working conditions.
The delegation first walked into the workshop production line and witnessed the entire process of hose pumps from precision processing of raw materials to intelligent testing of finished products. Our technical director demonstrated the operation of the new generation of high-pressure hose pumps on site: its original "double-layer enhanced hose" design can still maintain a stable flow rate under simulated extreme working conditions, and its life span is 3 times longer than that of traditional products; and the intelligent pressure feedback system can adjust the output parameters in real time, accurately matching the needs of complex scenarios such as shield machine mud transportation and tunnel grouting.
"During the construction of the Sichuan-Tibet Railway tunnel, our hose pumps ran continuously for 800 hours without failure, saving 40% of downtime maintenance time for the project." The case sharing of the project manager gave the delegation an intuitive understanding of the reliability of the equipment.
At the quality inspection center, the delegation witnessed the "millimeter-level" strict quality control: from material fatigue resistance test to whole machine load test, each hose pump must pass 200+ test indicators, far exceeding the industry standard. When seeing the experimental picture of the hose still being as flexible as before in a low temperature environment of -30℃, the head of the China Railway Equipment Department said with emotion: "Infrastructure projects often face extreme environments, and such quality reassures us."
China Railway Engineering Equipment Group Co., Ltd. purchased our products for in-depth application:
1. Hose pump for TBM
Scenario: In shield machine excavation, hose pumps are used to transport high-viscosity, solid-particle-containing slurry (such as bentonite, chemical slurry), which meets the needs of grouting reinforcement under complex geological conditions.
Technical highlights: Wear-resistant rubber hoses are used to increase service life by 30%; the seal-free design avoids leakage risks and supports 24-hour continuous operation.
Case: In a certain city subway tunnel project, the Gaodetec hose pump achieved a daily grouting volume of more than 500 cubic meters, with an efficiency increase of 40% compared to traditional pumps.
2. Grouting equipment for tunnel project
Scenario: For water-rich strata or weak surrounding rocks, a dual-liquid grouting system (cement-water glass) is provided to quickly solidify to form a water-stop curtain or reinforce the soil.
Technical highlights: Intelligent proportional control technology, error ≤1%; modular design supports rapid disassembly and assembly, and is suitable for operations in narrow spaces.
Case: In a cross-sea tunnel project, Gaodetec grouting equipment successfully controlled the water seepage rate below 0.1L/min to ensure construction safety.
3. Concrete linings and convey pea-gravel shotcrete pump for tunnel backfilling
Scenario: Used for backfilling pebbles behind the secondary lining of the tunnel to fill the gaps and enhance the structural stability.
Technical highlights: High-pressure conveying capacity (up to 10MPa) to ensure uniform distribution of pebbles; variable displacement design to meet different engineering needs.
Case: In a high-speed railway tunnel, the Gaodetec pea-gravel shotcrete pump achieved a daily backfill volume of more than 200 cubic meters, reducing labor costs by 50%.
4. Belt conveyor for connecting the shield machine
Scenario: Connect the shield machine with the slag treatment system to achieve continuous and efficient transportation of excavation slag.
Technical highlights: Wear-resistant conveyor belt (lifetime of more than 20,000 hours); intelligent deviation correction system reduces the deviation rate to less than 0.5%.
Case: In a long tunnel project, the Gaodetec belt conveyor achieved an average of 280 hours of trouble-free operation per month to ensure construction progress.
As a strategic partner of China Railway Engineering Equipment Group Co., Ltd., we will continue to deliver strong power to major projects with "zero defect" products and "24-hour response" services, and jointly write a new legend of China's infrastructure!
