MSS Underslung (2 sets in service)

MSS beam is situated under concreted bridge structure.

Maximum bridge deck width 16.5 m

Maximum bridge span 45.0 m

Minimum bridge clearance above the terrain 6.0 m

MSS is used for span by span construction of continuous beams. Economically effective use is

for viaducts with length of up to 250 m.

For MSS the great speed of the construction process is characteristic since it usually takes11 days for completing each span. Both MSS girders are supported directly on bridge piersor on pier foundations. It makes MSS independent of geological and terrain conditionsand allows for surmounting a variety of natural and man-made obstacles underthe bridge.

Underslung MSS is especially suitable for single beam bridge structures with either a linearor cranked bottom line. MSS superstructure consists of two steel box girders, placedunder the bridge superstructure and supported by triangle brackets, fixed to both sidesof the bridge pier column. On the brackets are launching wagons with hydraulic equipment

for vertical and horizontal MSS axis adjustment. Formwork for bridge beam and for sidecantilevers is fixed to MSS beams and real adjustment of bridge beam geometry is realisedby mechanical screw jacks. No other formwork operations are necessary before, duringand after launching MSS into the next span which speeds up the work procedures.

MSS beam is situated above concreted bridge structure.

Maximum bridge deck width 14.5 m

Maximum bridge span 45.0 m

Minimum bridge clearance above terrain 5.5 m

Minimum bridge local clearance * 1.5 m

* street clearance, other local obstacles

MSS Overhead is suited especially for double beam bridge structures with either a linearor cranked bottom line. MSS superstructure consists of one steel box girder, placed abovethe bridge deck and supported by a steel frame, standing on the pier head and penetratingthe bridge slab. Transversally to MSS girder there are steel brackets, on which the bridgeformwork is suspended by thread rods. Formwork geometry is horizontally adjusted bythe transverse position of the rods and vertically by their length. At the front end of MSSis suspended the prestressing platform, from which the strands are pulled into cable ductsand cables are tensioned by jacks after concrete has hardened.

More than 10 km of bridge structures have been built since the first set of MSS was putin operation in 2001. The most challenging was the construction of the cable stay bridgespanning the Odra River, with the main span of 105 m. This project documented a greatadaptability of MSS for building structures the parameters of which do not fit basic MSS data.

Equipment for balanced cantilever method Mobile concreting carriages (MCC)

Skanska owns 1 pair of MCC used for building the first bridge across the Orava river, and 3 pairsof BB used for building by which the cable stay bridge in Povazska Bystrica. MCC is specialisedequipment for building bridges by means of in situ cast segments starting symmetricallyfrom the pier to the centre of the span where the adjacent ends of next-door cantileversare connected by concreting of the closing segment. MCC are adaptable for any box girderbridge with respect to data below:

Type of MCC max bridge width segment length segment weight

MCC Orava 14.00 m 4.80 m 180 tMCC Povazska Bystrica 30.40 m 4.90 m 360 t

Cantilevering is a suitable method for building bridges crossing deep valleys or rivers by long

spans, where other known technologies have their limits. Skanska has become an experienced

contractor building these bridges in the Czech and Slovak Republics and in Poland.

FT is equipment used specially for concreting the bridge deck on composite bridges of steeland concrete type. Usually, pier sections of the deck are concreted first and, after the concrete

has hardened, the central sections are completed. Therefore two types of FT are in use pierFT and span FT. They are designed for bridges with spans of up to 45m but can be modifiedfor shorter or longer spans if needed.Two longitudinal beams are of steel truss construction while I profiles are used as transversebeams on which formwork panels (FW) are suspended by thread bars. After the concrete slabhas hardened, formwork panels are loosened and the FT is longitudinally launched in furtherposition by use of hydraulic cylinders. Supporting blocks with sliding bearings are weldedto the upper flange of bridge girders and protrude above the deck surface. External FW (underside cantilevers) is launched together with FT while internal FW (panels between bridge steelgirders) is launched independently on rails welded to the bridge girder webs.

The Skanska Post-Tensioning system is CE certified and comprises all partsand components necessary for installation of cable ducts, tendons, and anchoringand coupling of tendons made of 1 to 37 strands measuring15.5 (15.7) mm in diameter,and the strength of up to 1800 MPa. In a cylindrical anchoring plate, each strandis anchored by an individual conical wedge. For internal cables, steel corrugatedducts are used and tendons are grouted by cement mortar for corrosion protectionand cohesion. For external cables, polyethylene ducts are used along with cement groutas corrosion protection.

The system complies with the Czech standard SN P 74 2871. Its technical specifications

are in compliance with Article 4.4.- Anchoring, of Czech Government Regulation

No. 178/1997 Coll. , and with Decision No. 29/2006 of the Czech Office for Standards,

Metrology and Testing, dated of 30 August 2006. Furthermore, the system complies

Problems with dismantling (assembly) of bulky loads under bridge structures aresolved by the heavy lifting system, which can be used in inaccessible terrains underbridges. This equipment consists of a hydraulic cylinder and mechanical self-lockingequipment that facilitate anchoring the hydraulic cylinder. The equipment stroke dependson the length of the suspension cable and is not restricted by the available space.The maximum load is 400 t.

This technology is mostly used for movable scaffolding or whole formwork handling.Heavy lifting is top-notch hydraulic equipment that can reduce idle time and cutbuilding costs.

Pile load test

Technical data:

hydraulic cylinder 4x 250t

hydraulic pressure 71 MPa

ground anchor 8 pieces

A static test of a pile is to demonstrate that its loading capacity corresponds withdesigned load forces.

The load force is generated by means of a steel cap with 8 arms to which 8 ground anchors

are clamped. By prestressing ground anchors the axial force is introduced onto the pile head.The value of the force is controlled by electronic equipment which simultaneously measuresthe piles decline. The test results are evaluated in accordance with the Czech standards.

Construction of ground anchors is subject to individual design in accordance with geologicalconditions and applied force.

Test equipment is adaptable for testing the pile on horizontally acting force, i.e. the bendingeffect.

SKANSKA-type road safety fence for bridgesType SK-MZI, SK-MZII, SK-MZII-03, SK-MZII-04, SK-MZIII

The SKANSKA-type road safety fence is intended for use on bridges with low traffic(SN 74 3305) where the horizontal impact of pedestrians on the railing could occur.Safety of vehicle traffic is ensured using a different system (retaining system).

Product description by type:SK MZI

The system consists of a handrail fastened to columns distributed at a distance of 3000 mm.Vertical bars placed between the columns are no more than 120 mm apart.

SK MZIISimilar to MZI but, instead of columns, the frames are supported with short bars built intoconcrete and placed 3000 mm apart.

SK MZII 03, SK MZII 04

Similar to MI, but the frame is additionally supported with short columns. Vertical bars are ofa round or rectangular profile.


34/58

SK MZIII

Similar to MZI, but with columns and frames of L-shaped bars. This system is designedspecifically for railway bridges.Fence installation

There are two methods used for fastening columns to the pavement:1. Sockets are formed in a concrete base into which the bottom end of the columns is placed

and then concreted with special mixture.2. The column is fixed to the pavement with bolts via an anchor plate. The bolts are either

sealed into bored holes or screwed into the built-in anchoring component. The plate sits onspecial mortar to allow for levelling and adjusting the column.
