Temeltek has professional engineering experience and the full range of techniques to provide reliable retention witth deep excavations supporting systems. Although there has been much advancement in the construction retention techniques, it is possible to face the same challenges of the early builders faced in the past. The soil structure, depth of cut and ground water, weather conditions, superimposed loads, seismic loads, vibrations, and adjacent construction are the factors which determines the complexity of the design structure of the deep excavations supporting systems. Because of the conditions of the location including wet soil, sandy soil or backfilled earth structure, the shoring systems can also be complex. Hard rock in the surrounding in earth structure can even be hazardous fort he construction design of the deep excavations supporting systems.
As a result of the surrounding structures, construction machinery, and load of the materials including soils near to the excavations, lateral loads are created during the construction of deep excavations supporting systems. As the conditions do not permit heavy loads to be located withing the zone of the influence of the deep excavation supporting systems, it minimizes or eliminates the load. On an excavation wall, underpinning the surrounding structures can reduce the rate of the loading and minimize the risk of building settlement. Vibrations from such sources as traffic, railways, blasting, and machines operated in adjacent buildings can incluence the area where the deep excavations supporting systems are installed.
Steel sheet piling, soldier piles and lagging, jet or chemical grouting, secant or tangent piles and soil nail walls are the common permenant and temporary deep excavations supporting systems. Provision of lateral support of sheeting and shoring systems can be achieved by utilizing anchors or bracing equipment. A circular supporting system designed as a compression ring to resist loading can be included in the access shafts for tunnelling and trenchless construction.
Precautions regarding the weather conditions shall be taken into account when planning the construction of the deep excavations supporting systems for excavations for extended periods.
During any excavation supporting hazardous and risky conditions exist in the overall contruction, then the safety and safe operation method are a great importance fort he safety of the employees as well as the surrounding structures. Temeltek as a possessor of zero accident princible, anticipates the hazards associated with the deep excavations supporting systems and the trench safety.
Extreme caution must be used during any deep excavation supporting activity and safety is of utmost importance. Temeltek understands the hazards associated with supporting systems and the importance of trench safety.
