what are piled retaining walls

  • piled retaining walls. 250mm 750mm. Retained heights up to 6m (cantilever) and 10m (propped). Contiguous bored and secant walls, designed as either free cantilever or propped, provide a vertical face construction in dry or water-bearing soil conditions. This method of piling creates a retaining wall to restrain the strata while excavations are carried out to form basements or to maximise the useable space on a site. Piles may form part of the permanent structure or be used solely& ...


  • of deepEx on secant pile walls with our technical experts. Soldier Pile and Lagging Wall (Berliner Wall) Soldier pile and lagging walls are some of the oldest forms of retaining systems used in deep excavations. These walls have successfully being used since the late 18th century in metropolitan cities like New York, Berlin, and London. The method is also commonly known as "Berliner Wall" when steel piles and timber lagging is used. Alternatively, caissons, circular pipes, or concrete& ...


  • Embedded retaining walls are used in a wide variety of civil engineering applications including for embankment stabilisation, construction of basement walls, underpasses or tunnel approaches, in ground tanks and other buried structures. The most appropriate system depends upon a number of factors including soil and groundwater conditions, retained height, acceptable deflections and propping options, desired wall geometry and design life. The cost of retaining wall construction& ...

  • For more than five decades piles, structures made of piles (pile wall, pile box, etc.) and pile-like structures (sockets, shafts, slurry trench walls, etc.) have been applied for retaining structures in. (creeping) slopes. In the late sixties of the 20th century the boom of motorway and highway construction began in the Alpine region (e.g. A10 Motorway “Tauernautobahn”, Austria). Since that time design tools and execution of structural measures have been sophisticated, novel& ...


  • Type of building work. A 4-storey condominium with two basement was to be built on a slope of a hill. There are completed multi-storey condominium buildings at the top of the hill. A row of reinforced concrete contiguous bored pile (CBP), of diameter between 900mm and 1,100mm, was constructed to act both as earth retaining structure for the excavation for basement construction works as well as the permanent wall for the basements. The CBP were embedded between 8m and 15m& ...


  • Contiguous and Secant piled walls. These two different methods of retaining wall construction employ bored piling techniques, usually CFA or Rotary. Used when the available workspace dictates that basement excavation is vertical, both methods offer technically effective and cost efficient solutions for retaining the sides of bulk excavations, even in water bearing soils. The techniques are most common in large commercial basement projects as they avoid excessive& ...


  • In urban ground engineering and sub-structure construction, piled walls have become ubiquitous, allowing basement construction to extend many storeys below ground level. Used as either temporary or permanent works, piled walls can provide high stiffness retaining elements affording large excavation depths with minimal disturbance to surrounding structures, properties or utilities. Using either CFA or Large Diameter Piling (LDP) techniques we offer both secant and contiguous& ...


  • The use of retaining wall systems of all types has become more highly saught after as developers try to make maximum use of available space or design in underground structures. R&A offer in-house designed bored pile retaining wall systems to suit all requirements. Bored pile solutions to excavations often minimize the need for additional support measures and can maximize the available excavation. Temporary or permanent work solutions can be provided. As with all geotechnical& ...


  • retaining walls. Bachy Soletanche has extensive experience in the design and construction of structural retaining walls for all temporary and permanent requirements. Our expertise spans a wide variety of ground conditions, in both urban and green field environments. Bored pile walls (contiguous or secant) can be the ideal solution for more restricted sites when the wall is constructed using continuous flight auger techniques or with temporary casings. We have designed and built a& ...


  • Contiguous piled Wall. Contiguous piled retaining walls are formed using either Rotary or CFA piling technics, piles are installed at close centres, with typically 100-200mm gaps between piles. These piles form temporary or permanent support to excavations. This techniques is suitable for basements, underground structures and motorway cuttings where working space is limited or adjacent to existing structures.


  • Bored pile walls (contiguous or secant) can be the ideal solution for more restricted sites when the wall is constructed using continuous flight auger (CFA) techniques or large diameter auger (LDA) with temporary casings. We have designed and built a number of hybrid retaining walls in appropriate ground conditions as cost effective alternatives to sheet piling. Bored piles can be constructed through bentonite cement slurry with lateral loading on the wall carried by “arching” between& ...


  • We are expert in Contiguous Piling for retaining walls for new basements as well as piled new foundations, piled underpinning and traditional underpinning of existing buildings. Purkelly provide a specialist design and build service for the construction of piled retaining walls for new basements. A contiguous piled wall is formed from closely spaced bored piles for the construction of basements. This specialist service is available to builders, main contractors, professional advisors and& ...


  • SHEET PILE walls - retaining SYSTEMS FOR DEEP EXCAVATIONS: Sheet Pile walls. Sheet pile walls are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of it being hammer driven. The full wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section. Steel sheet piles are most& ...


  • Bored pile retaining walls have many uses, basement construction, cut and cover bridges, bank stabilisation and road/rail cuttings, but the system which you may need will depend heavily on certain factors; Ground conditions, Retained height, Ground water and Deflection, etc. At Advanced Mini Piling Systems we provide: Rotary Bored Contiguous piled walls. CFA Contiguous piled walls. Secant Contiguous piled walls. King Post walls. Driven piled retaining Wall. CFA Contiguous& ...


  • Sheet pile retaining walls are usually used in soft soil and tight spaces. Sheet pile walls are made out of steel, vinyl or wood planks which are driven into the ground. For a quick estimate the material is usually driven 1/3 above ground, 2/3 below ground, but this may be altered depending on the environment. Taller sheet pile walls will need a tie-back anchor, or "dead-man" placed in the soil a distance behind the face of the wall, that is tied to the wall, usually& ...


  • piled retaining walls. We can construct contiguous, secant or Kingpost walls using CFA and rotary bored or mini piling methods and therefore almost all ground conditions can be accommodated for permanent or temporary retaining walls. Bored pile walls are a very cost- effective means of retaining ground and can also be installed in restricted locations. walls are normally formed utilising diameters of 450mm to 1200mm diameter dependent on the retained height and degree of& ...
