Unconfined Compressive Strength 2,000 PSI.

The tunnel will transit soft ground and rock along each end of the tunnel alignment and mixed face conditions shall be anticipated for reaches along these subsurface transitions with the following expected proportions:

-  23 % of soil engineering units 1 and 2,

-  63 % of the rock engineering unit and

-  14 % of mixed ground.

LOVSUNS Tunneling Canada Ltd.

LOVSUNS, former Lovat which was sold to Caterpillar, carried on the Tunnel Boring Business as the wholly owned subsidiary of Liaoning Censcience Industry Co. Ltd. – LNSS only one month after the Caterpillar Tunneling assets were sold to the Chinese LNSS in November 2014 with the order of the 3.9 m diameter EPB TBM to bore two wastewater tunnels in Istanbul, Turkey.

Further TBM orders for several drives of the new Metro Line extensions followed. "We designed and engineered tailormade TBMs for Istanbul and now for the US-market in Toronto and completely produced the TBMs in the facility in Liaoyang China. That means that we very successfully united the best practice, knowledge and technology of both companies for the highest advantage of our customers", explains Hongyu Xue, General Manager of LOVSUNS Tunneling Canada Ltd.
