Secant Piles. Secant Piles are formed by constructing, intersecting reinforced and non-reinforced concrete piles. The secant reinforced with either steel rebars or with steel beams they are constructed by drilling or auguring.
In secant pile shoring, primary and secondary piles are interlocked to form a continuous wall. First of all, a guide beam is created before the installation to keep the alignment in place. Mostly it is used during deep excavations. After casting the primary pile, the provisional casing is extracted. Then, secondary piles are instantly drilled.
Contiguous and secant bored pile walls. Grout-injected mini piles. Compaction, pressure grouting. Ground treatment. De-watering by well points and deep wells. Underpinning and stabilization of failed foundations. Ground and retaining wall anchors. Ground works including. Foundation engineering including. Building works and services. Pile testing
piles with a typical interlock of 150mm. These walls may need a reinforced concrete lining for permanent works applications, depending on the particular requirements of the project. Secant Wall – Hard/Hard Hard/hard wall construction is very similar to a hard/firm wall but in this case the primary piles
In a tangent pile wall, there is no pile overlap as the piles are constructed flush to each other. The main advantages of secant pile walls are: 1. Increased construction alignment flexibility. 2. Increased secant pile wall stiffness compared to sheet piles. 3. Can be installed in difficult ground (cobbles/boulders).
Concrete pile trimming using a proprietary hydraulic concrete cutter suspended from excavator or crane for piles of up to 1500mm in diameter. Excavation works for basement construction or pile caps/ground beams. Pile cap and ground beam construction or substructure concrete works associated with basement construction.
Piles in a secant wall are spaced at 0.8 to 0.9 pile diameters. Primary piles are secanted by secondary piles, thus providing a closed structure to act as a barrier in water bearing soils, and to prevent the ingress of soil between the piles. Capability: Depending upon ground conditions, using CFA or LDA technology, we can build from 600mm to ...
The works include the challenge of installing the 2.1m diameter piles of the oversite development at the WTH among the tight constraints set by the new tunnels. The piles have also been designed to carry the negative skin friction and the bending moments induced from the construction of the future Crossrail tunnels and the adjacent Shafts.
The secant piles are reinforced with either steel rebar or with steel beams and are constructed by either drilling under mud or augering. Primary piles are installed first with secondary (male) piles constructed in between primary () piles once the latter gain sufficient strength. Pile overlap is typically in the order of 3 inches (8 cm ...

Our focus is on the following scope of works : All kind of foundation piles ; Shoring systems such as secant and contiguous pile walls, diaphragm walls etc. Temporary and permanent ground anchors ; All kind of grouting and sealing works (low and high pressure grouting) Complete enabling work packages including excavation and dewatering
Problem. The project involved the construction of a sewage treatment plant (STP), a 16.5 km Deep Gravity Sewer (DGS) with 50 Shafts and network connections. The shafts were constructed with 42-54 secant piles, to facilitate and receive the micro-tunneling heavy equipment and pipes that would be 'jacked' into position for the sewer network.
About Us. Established in 1998, Gulf Tunneling Company – LLC (GTC) is now one of the leading companies in the Microtunneling fields in the UAE. GTC had proven its expertise in the market by securing and executing multiple tunnelling projects of more than 60000m. If playback doesn't begin shortly, try restarting your device.
Construction of secant pile wall is normally required when the building project is to be erected on soft ground or sandy soil. The purpose of this is to ensure that the strata behind the wall would remain undisturbed during construction and to ensure safety from the risk due to high lateral pressure. 1. Title Method Statement for Building Secant Pile Wall and the Necessary Shoring 2. Scope of ...

A secant pile wall is a type of bored pile retaining wall consisting of a system of interlocking reinforced concrete piles. Secant-piled walls can be constructed using either Continuous Flight Auger (CFA) or Bored Cast-in-Place (CIP) methods. The interlocking piles typically overlap each other by about three to five-inches and are reinforced ...

We provide expert design build solutions for all types of Piles and deep foundations, Ground improvement and other specially geotechnical areas. We deliver safe projects to the highest quality which meet and often exceed ...
Successful delivery of over 40 varied projects including large diameter bored piling, retaining structures comprising diaphragm wall, secant piles, contiguous piles, sheet piles, etc., ground improvement works, high pressure injection (jet grouting) and anchoring, sometimes adjacent to or in close proximity of the MRT tunnels.
The secant pile wall was designed to cantilever for an excavation depth of up to 8m to facilitate the construction of the underbridge. The approach walls were installed during normal working hours, with the lengths crossing the railway line installed during shorter night time possessions in …
D.J. Scheffler & Nye specializes in Continuous Flight Augur (CFA) Secant Pile Shoring for coastline (and other) basements, and Deep Foundation work.
Secant pile walls are formed by constructing reinforced concrete piles that interlock, and are often used as a cost-effective solution when short-term water retention is required. Secant piles are reinforced with either steel rebar or steel beams . Typically, primary () piles …
Elios S.r.l. ago 2019 - Presente2 anni 3 mesi. Livorno Area, Italy. Environmental remediation project for the main urban waste land field of the city of Livorno, Italy. The major technical activity performed is the construction of a waterproof cement bentonite diaphragm to seal off the leachate contained. The cement bentonite wall is 1300m long ...
The success of a secant pile system requires that the individual piles be structurally sound over their full length, and that adjacent piles be constructed to tolerances that maintain a reasonable overlap between the primary and secondary piles. Secant pile walls for excavation support are designed to function in one of two ways. The
