What is Socketing in pile?
What is Socketing in pile?
Rock socketing of piles is mainly done to utilize the full structural capacity of piles. Since rock socketed piles can be designed to carry compressive loads by skin friction and end bearing, it is necessary to collect all details mentioned above.
How do you measure your pile size?
The pile length is often determined by meeting the geotechnical strength limit state (Eq. 1). Pile lengths are typically finalized during construction using Rnfield measured from a field analysis method. In the design phase, pile resistances from field analysis methods, Rnfield, are not available.
What is a pile rock socket?
The term ‘socket piles’ (or rock sockets), refers to a technique that is used to embed a pile into solid rock. This can be necessary to utilise the full structural capacity of the piles for both compressive and tensile forces.
How is chisel energy calculated?
CALCULATION OF CHISELING ENERGY: = 0.75 x 1.5 x 6.8/7.8 x 0.8 = 0.7846 Tonne -meter. Area of 400 mm diameter of pile = pi x (0.4)2 /4 = 0.1257 m2. Therefore, equivalent energy for 400 mm diameter at pile for ‘n’ blows.
What is bored pile?
Bored piles are cylindrical bodies made of concrete (with or without reinforcement) which are installed in the ground by a variety of methods. They transmit high structural loads into lower, load-bearing soils.
How is depth of piles calculated?
General factors to be considered for determining depth of foundation are:
- Load applied from structure to the foundation.
- Bearing capacity of soil.
- Depth of water level below the ground surface.
- Types of soil and depth of layers in case of layered soil.
- Depth of adjacent foundation.
What is pile toe level?
Pile toe – A pile’s lowermost end. Redrive – A substantial number of impacts, or a substantial time of vibration, which significantly deepens the pile’s toe elevation.
What is caisson pile?
Bored Piles, also known as drilled shafts, cast-in-place piles or caissons, are constructed by drilling and excavating a slender, cylindrical hole and backfilling it with reinforcing steel and concrete.
Which is the most suitable boring method in hard rock formations?
Cluster drilling is a proven method to penetrate rocks with strengths exceeding 100 MPa. The method has been used successfully for decades in America, Asia and Europe for applications in the mining and construction industry with diameters usually ranging from 600 to 2400 mm.
How do you terminate piles?
Pile penetration ratio and chisel energy level are two methods that are used to decide the termination depth of a pile. Through these methods, an optimized length can be specified for the pile under consideration. Hence, these two methods are used for establishing similarity in soil strata.
What is pile termination criteria?
The study presents a pile termination criteria based on rock classification which includes geological identification of rock and rock strength assessment using breakability, penetration and scratch tests. The piles were subjected to compressive stress of 18.75 MPa.
What are socket piles and what are they used for?
The term ‘ socket piles ’ (or rock sockets ), refers to a technique that is used to embed a pile into solid rock. This can be necessary to utilise the full structural capacity of the piles for both compressive and tensile forces. It is a technique that is typically used for offshore applications, such as drilling into a rocky seabed,…
What kind of wrenches are in socket set?
The Dewalt socket set comes with wrenches that provide a 5-degree swing arc for easy maneuvering. This also allows it to be used in tight spots. The Dewalt socket set comes with wrenches that provide a 5-degree swing arc for easy maneuvering.
How is the socketing depth of a pile determined?
The socketing depth of a pile is decided based on several factors. Some of them are information gathered from the borehole log, rate of the penetration in the rock, rock sample observation, etc. Further, onsite tests such a point load test could be done to find the strength of the rock. It can be correlated with the end bearing of the rock.
Why are socket piles used in offshore drilling?
This can be necessary to utilise the full structural capacity of the piles for both compressive and tensile forces. It is a technique that is typically used for offshore applications, such as drilling into a rocky seabed, where the depth is shallow or there is sloping solid rock.
