## What is rock socket length?

The rock-socket lengths range from 0.4 to 60 m. Variables considered were the base resistance and shaft resistance in rock, the shaft resistance in soil, the pile head load, the ratio of socket depth to diameter and rock strength. Values of rock socket length are suggested based on analysis of the database.

## How do you calculate pile socket length?

shear strength of rock in socketed area, T/m2 α = shaft adhesion factor, varies from 0.3 to 0.9 and ls = socket length in m Rock socket length can be calculated by knowing the shear values of rock. Designing of rock socketing length of pile in weathered/soft rock can also be calculated based on energy criteria.

What is rock socket?

The term ‘socket piles’ (or rock sockets), refers to a technique that is used to embed a pile into solid rock. This creates a void around the outer edge of the pile which is filled with grout, usually Portland cement or an ultra-high strength grout depending on the structural requirements.

### What is socket depth?

This is the internal depth of the socket that the bolt or fastener head can travel into. Deep sockets have a much greater opening depth allowing the bolt head to travel up into the socket. You may need a socket with a longer opening depth if you need to turn a nut on a long bolt shaft.

### Is code for rock socketed pile?

Geotechnical investigation data as laid down as per IS 1892, IS 13063 or any other relevant IS code. The rock profile, contours, the geological data and the necessary information as listed in IS 13063 along with the engineering and physical.

What is a end-bearing pile?

End-bearing piles develop most of their load-bearing capacity at the toe of the pile, bearing on a hard layer of rock or very dense soil and gravel. The pile transmits the load through soft, compressible strata directly onto firm strata. This type of pile therefore acts in the same way as a column.

## Is code for piling?

Following are the Indian Standard Codes on Pile Foundations: IS 2911 : Part 1 : Sec 1 : 1979 Driven cast in-situ concrete piles. IS 2911 : Part 1 : Sec 2 : 1979 Bored cast-in-situ piles. IS 2911 : Part 1 : Sec 3 : 1979 Driven precast concrete pile.

## What is a end bearing pile?

Is 2911 Part 4 load test piles?

Broadly, piles transfer axial loads either substantially by friction along its shaft and/or by the end-bearing. The portion relating to load test on piles has been covered in a separate part, namely, IS 2911 (Part 4) : 1984 ‘Code of practice for design and construction of pile foundations: Part 4 Load test on piles’.

### What is a socket length in a pile?

This term gets used in end bearing piles. The depth up-to which the RCC end bearing piles must be penetrated within the Hard Rock is known as the socket length.

### Where are rock socketed shafts for highway structure foundations?

What is the minimum wall thickness for a driven foundation?

Driven Friction Pile Foundations Determine minimum pipe pile wall thickness per Construction and Material Specifications, Section 507.06.D, UBV / 900 kip/in Ensure Wave Equation Drivability Analyses correspond to Static Analyses (typically GRLWEAP versus DRIVEN)

## What is a socket and what is it used for?

Sockets are an endpoint, or an abstracted interface you can say, which can be used to communicate between two machines.
