Singapore Tunnels Gain Precision with REED Mine30 Electric Pump

In the intricate underground construction projects of Singapore, a critical tunnel lining operation is being efficiently advanced with the help of sophisticated machinery. The REED Mine30 electric-tracked concrete/sprayed concrete pump has recently demonstrated remarkable performance at a local underground tunnel construction site, providing stable and reliable concrete supply for the tunnel lining process.

The equipment's exceptional low-flow control capabilities and strong material adaptability make it perfectly suited to meet the stringent requirements for precision and efficiency in tunnel construction. Its compact tracked design offers excellent maneuverability in the confined tunnel environment.

The concrete delivery process is particularly noteworthy: material is fed directly to the pumping point via a rail-mounted concrete mixer truck within the tunnel. This efficient supply method minimizes manual handling and ensures continuous operation.

Operators reported maintaining the REED Mine30 pump at approximately 25 strokes per minute during this project. While this represents a relatively low flow output, the Mine30 model's ability to adapt to such low-flow demands is precisely what makes it exceptional. For tunnel lining projects requiring precise control over concrete pouring thickness and uniformity, the capability for slow, steady pumping is crucial—factors that directly impact lining quality and structural stability.

Of particular significance is the project's use of steel fiber-reinforced concrete . While increasingly popular in tunnel engineering for its enhanced crack resistance and durability, steel fibers typically present pumping challenges, often causing pipe blockages. The REED Mine30 handles this demanding material with ease, demonstrating both powerful pumping capacity and compatibility with complex mixtures.

The project team plans to operate the REED Mine30 pump continuously for about 10 hours per pouring session , putting the equipment's reliability and durability to the test. Its successful application in this Singapore tunnel lining project not only demonstrates professional capability in underground engineering but also provides valuable reference for future similar projects.
