You might think that tunnels are always built by professionals, with an obvious and practical purpose — to transport people, to reach a deposit of coal or diamonds, to transport water, and so on. For some, however, digging a tunnel is a hobby, a distraction, an escape, a way of expanding their houses underground or even a way to exercise — we look at some of the tunnels built by ordinary people around the world. 1.

A selection of current construction work and studies shows hydropower’s wide range, says Patrick Reynolds. Numerous hydropower and pumped storage projects are in construction or planning across the globe, and International Water Power & Dam Construction (IWP&DC) briefly notes progress and developments on a selection in Asia, Europe, North America and South America, and also the Middle East.A major hydropower scheme that is well advanced is the Ulu Jelai project, in Malaysia. Being constructed by Salini Impregilo, the project involves significant surface and underground works.Both surface and underground works feature in the Foz Tua pumped storage project, in Portugal, and which is also at an advanced stage. The project involves construction of a 108m-high double-curvature arch dam.Developing hydropower where a new dam is not needed, efforts are pushing ahead in the US to exploit existing lock and dams structures, such as the run-of-river projects being undertaken by power company American Municipal Power (AMP) on the Ohio River. The plants under construction include 72MW Smithland.Statkraft may give the go-ahead this year for two run-of-river projects in Chile, following an acquisition in 2015. However, following a recent review of its investment programme it has yet to decide what action it will take.Many further projects are coming, and a few among those include recent awards for consultants MWH Global and ÅF, respectively, in South America, Europe and the Middle East.Malaysia: Ulu JelaiConstruction of the 383MW Ulu Jelai hydropower project, in Malaysia, has been underway since 2011 and is well advanced, including the recent milestone completion of the Susu roller compacted concrete (RCC) dam.Ulu Jelai is being developed by Tenaga Nasional Berhad (TNB) in Pahang state, approximately 200km north of the capital Kuala Lumpur. It is one of five hydro projects being built at present to help stabilise the power grid.The project is located on Bertam River, and involves major dam and tunnel works. The rated net head of the scheme is approximately 360m.Key features of the project include the Susu reservoir on Bertam River, and to which water is conveyed by transfer tunnels from the Lemoi and Telom rivers, running on opposite sides of the main river. Lemoi and Telom are tributaries of Bertam and naturally join the main river downstream of the project location but are being tapped with offtake weirs at higher elevations. The tunnels have lengths of 7.5km and 8.5km, respectively.Water flows from Susu reservoir down a 9.5m-diameter unlined headrace tunnel to the underground powerhouse complex, holding a pair of 191MW Francis turbines. Ulu Jelai is expected to generate approximately 326GWh of electricity annually.Salini Impregilo is main contractor on the scheme, which is nearing completion.The Susu RCC dam is more than 80m-high with a crest length of 512.5m. Its volume is approximately 750,000m3, the contractor said.The volume of other concrete works on the project is approximately 190,000m3. Surface excavations and earth moving has involved more than 3M m3 of material.Underground construction has been performed by both TBM boring and drill and blast excavation. In total, the project has called for excavation of 26km of tunnels and also the powerhouse cavern complex. The TBMs were used to bore 15km of tunnels, and 11km of excavation of undertaken by drill and blast.Salini Impregilo notes that the total underground rock excavation is approximately 800,000m3.

Hitachi displayed three new excavators and a wheel loader at Bauma in April. The new ZX19-5 mini excavator, to be used on construction projects, is designed to be user-friendly. According to the manufacturer, the Zaxis-5 model offers high levels of performance, stability and easy maintenance. The boom cylinder, in the new excavator, has been moved on top of the boom to protect from potential damage, making it more efficient when working on narrow spaces, as its front minimum turning radius is smaller. A new folding travel pedal can now be used instead of the hand lever, improving the operation speed. Other improvements include the placing of the hydraulic hose inside the boom and the addition of a new blade, capable of making digging more precisely.There is also more space between the operator and the front window and more legroom in the cab. The cab has a new design that features a large LCD monitor located on the right-hand side, displaying the vital technical data, including the machine’s status and settings and a drinks holder for easy access to refreshments. Security has been improved, with an optional theft deterrent system that requires a four-digit number to unlock before the engine can be switched on.Hitachi also showcased the ZX300LCN-6 super long front medium excavator. The excavator has a six-cylinder 186kw stage IV-compliant engine, with the highest output in its class, and offers 14% higher productivity in PWR mode. Delivering lower fuel costs, the machine was specially designed for earthmoving on dredging, bank maintenance and slope finishing projects. The excavator also features a reconfigured lower roller that ensures mud falls out easily, an expansion tank that cools the engine parts, and enlarged track guards.The tilting rotator and tilting bucket modes are also included within its attachment support system.The new ZX490LCH-6 large excavator was designed to meet the demands of large-scale construction projects, set to offer a high level of durability without compromising efficiency. It features a boom reinforced with thicker plates and an undercarriage consisting of robust components such as track link, master pin, idler pedestal and bracket and upper roller bracket. The large excavator also incorporates an in-cab console, made of weather-resistant AES-grade resin that prevents UV rays damage, and sealant to eliminate any heat deterioration. These ensure the machine’s long-term cooling and low-noise performance.This excavator is able to save up to 5% fuel in eco mode with the same productivity as previous models, due to the use of HIOS IIIB technology. The after-treatment device helps the machine produce fewer emissions and to have a quiet performance. Furthermore, attachments to carry on different tasks can be easily fitted to the versatile machine that uses the attachment replacement support system.Also launched in Munich was the ZW370-6 wheel loader. With enhanced performance and low fuel consumption, the machine employs a new EU Stage IV-compliant engine that does not require a diesel particulate filter, which reduces maintenance costs.The wheel-loader has a 360° panoramic view from the spacious cab and a rear-view camera, visible on the multifunctional LCD monitor. Less noise can be heard within the cab thanks to an improved sound isolation. A smooth operation is ensured by the optional Joystick Steering System, which enables operators to reach high levels of productivity with effortless steering, it is said.There are also two types of lift arm available that customers can choose, depending on the required application.
