ROAD & HIGHWAY

PROJECT BOOKOver 65 years opening the way underground

PRESENTATIONOSSA, founded in 1952, is a leading company in the underground construction sector specializing in three business

areas: Construction, Energy and Mining.

Both in underground excavations by traditional method (NATM), as well as in tunneling with TBM, and roadheader mining,

OSSA is a solid underground works partner for important industrial and construction groups internationally. At OSSA

we are highly commited to Quality, Health and safety, and Environment, and we invest in Research and Development

Projects at an international level. We promote a culture of respect and teamwork among our team.

OSSA has vast recent experience both in high speed railway tunnels with over 60 km of high speed rail tunneling projects

in the last five years, leading the Spanish market in this specialty, and also in underground power plants, having built

over fifteen underground plants with some of the largest underground caverns in the world. As a recent highlight, we are

participating in the design and construction of the Hong Kong to Shangai High Speed Rail Line.

Internationally OSSA has executed works in Hong Kong, Taiwan, Chile, Peru, Colombia, Panama, Costa Rica, Brasil and

Nicaragua and is recently focusing its tendering activity in North America, Central America, Asia, Canada and Great Britain.

After 65 years of success, our strategy is to continue expanding internationally, and to support large civil engineering and

mining industry clients at all levels, contributing our vast technical expertise and our equipment fleet, while prioritizing

health and safety and innovation in all our projects.

SAFETYSafety is Obras Subterraneas, S.A.’s main asset from the time when its operations begin, demanded by the specialisation

required for the works carried out underground.

The company’s staff have a high degree of professionalism and specialisation, which has been achieved after many years

of training and the transfer of know how. Working in confined spaces with the presence of gas, dust, noise, low visibility

and the use of explosives means that the Obras Subterraneas, S.A.’s security department is the most relevant in the

company.

The use of cutting-edge, innovative techniques in the field of underground works requires the continuous training of the

company’s human resources.

The work consists of the excavation and support, using top heading and benching, of three road tunnels with a trunk section of 21.1 m x 11.4 m. The total length of the excavation of the 3 tunnels is 595 m (240 m, 235 m, 120 m), with a longitudinal slope of between 0.3 to 3.0% and a maximum and minimum overburden of 40 m and 12 m respectively. The excavation will be done using conventional means. The supports used will be based on: Shotcrete, corrugated grout rock bolts, metallic trusses with IR type profile 203 x 59.6k kg/m. The final reinforced concrete lining will be installed to thickness of 40 cm. During this stage 6 false tunnels will be also be built, one for each tunnel mouth, resulting in a total of 245 m of false tunnels.

The works included the building of two parallel tunnels, walls to protect the river banks, channelling of two streams, building of approach roads.

The main work is the building of the double road tunnel with two lanes per carriageway. The two tunnels were connected by eleven cross galleries, 8 of which are for pedestrians and with a cross section of 18 m2 and three for vehicles with a cross section of 35 m2. The galleries are situated at a distance of 240 m from each other.

The distance between the tunnel axes is 32 m, and a 17 m2 gallery will be built between the two tunnels, the front of which will be 150 m ahead of the tunnels in order to survey the ground to be excavated; the coverage does not allow for prior reconnaissance. This gallery will later be used for mounting installations. Shotcrete, 4 m long bolts, steel ribs TH - 29/HEB180, Bernold plate and concrete lining. Portals: micropile umbrella and forehole joint beam.

Two two-lane urban road tunnels, with a false tunnel between the two. Sa Mola and Llampaies tunnels with lengths of 1,100 and 115 m respectively. The Sa Mola tunnel has two emergency exits, one in a 200 m gallery and the other in a false tunnel.

In karst areas there are irregularities or chimneys requiring additional support in specific areas of the tunnel.

Because of the filtrations caused by the four faults crossing the tunnel, the latter is waterproofed with a sheet of reticulated polyethylene.

Pioneer work in compliance with Royal Decree 635/2006 on safety requirements in road tunnels.

The work included the lining of 500 m of a stream, the building of a 45 m skew box and various improvements in the adjacent urban roads.

Each tunnel has a length of 255 m and an average cross section of 120 m2. The tunnels were excavated with explosives and in the areas where the ground is of a lower quality, mechanical means were used. 6,403 m³ of shotcrete H - 250, 15,323 m of bolts AEH - 500 Ø = 25 mm and 2,292 m steel ribs TH - 29. 1,122 m² of wire mesh 5 x 15 cm and Ø = 6 mm is requiered in some stretches.

Excavation in semi-competent materials with low compressive strength, making the tunnel extremely difficult to excavate. 1920 ml. Injected cement and bentonite to achieve stabilization of the southern exit portal.

L = 4 m bolts, HEB160 trusses and shotcrete over welded wire mesh. 30 cm thick mass concrete lining.

In addition, several engineering works were carried out as well as road surfacing.

One of the main jobs was the construction of the Salt Tunnel, with a length of 297 m and a cross section of 52 m2. The tunnel was excavated with explosives and mechanical means. Excavation of the main section. Excavation, by trenches, of the gables. Immediate concreting of the gables.

A 43 m false tunnel was also implemented, and several drainage works, both transverse and longitudinal. Also worth mentioning is the building of a skew bridge with 17 m prefabricated girders and a 45 m continuous slab bridge, as well as the additional works of reinstatement of services and laying of the road surface.
