What is an H pile in construction?
H-Piles are structural beams that are dimensionally square, most commonly driven into the soil for deep foundation applications to support large buildings and bridges.
What is pile 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.
What is an H pile beam?
H-Piles are dimensionally square-structural beams designed for deep foundation applications. Where other pilings would struggle to penetrate, H-Piles can be driven deep into the ground to reach the necessary soil properties to support buildings and bridges.
What is socket length pile?
The piles are 6- to 120-m long and have diameter between 0.5 and 3.0m. 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.
What are H-piles used for?
H-piles are commonly used as bearing piles in deep foundation applications and are driven into the ground to support bridges, buildings, factories, stadiums, and nearly every other type of structure. H-piles are also used in other applications as bracing systems for cofferdams, and in beam and lagging walls.
What is steel H pile?
H-piles: H-piles are proportioned, especially, to withstand the large impact stresses during hard driving. The flanges and the web are rolled with equal thickness in order to eliminate damage on thinner parts.
What is socket depth?
Generally speaking, 3/8 inch (9.5 mm) is the most popular size in the auto repair industry.
How do you calculate pile socket length?
The surface area of the pile in socket length is calculated by multiplying the socketing length(length of the pile in the fresh rock) by the perimeter length of the pile. Generally, piles are socketing depth around the diameter of the pile unless it is specified in the geotechnical report.
What are H piles used for?
Is H beam stronger than I Beam?
The cross section of the H beam is stronger than the cross section of the I beam, meaning it can bear a greater load. In comparison, the cross section of an I beam can bear direct load and tensile but cannot resist twisting because the cross section is so narrow. This means that it can only bear force in one direction.
What is socket size?
Socket sizes are determined by the size of the socket head and the size of the drive socket. An example of a typical socket size is a 13mm socket with ¼” drive. Although socket heads are available in both metric and imperial sizes, the ‘drive socket’ size of a socket is always imperial.
What is PPR in pile foundation?
The pile penetration ratio (PPR) is used to ensure that the desired rock layer is reached during the construction process. The actual pile termination point is determined based on the energy requirement of the rotary piling rig for a specified PPR.
Which way is H beam strongest?
What are different types of sockets?
Three types of sockets are supported:
- Stream sockets allow processes to communicate using TCP. A stream socket provides bidirectional, reliable, sequenced, and unduplicated flow of data with no record boundaries.
- Datagram sockets allow processes to use UDP to communicate.
- Raw sockets provide access to ICMP.
How is pile socket length calculated?
In all cases the minimum length of socket is 2 times the socket diameter of pile.
What is the capacity of H pile?
This pile is a replacement pile. The capacity of Pre-bored socketed H-pile is approximately 6,000kN per pile. The pile is required to drill into rock. The capacity of pile is governed by capacity of H-pile, bond between H-pile and grout and bond between grout and rock.
What is a socketed pile used for?
Piles socketed into rock are often used to support heavy loads from buildings and infrastructure. Piles typically of up to 1·8 m diameter carrying safe working loads of up to 40 MN are utilised in Australia. Their design has traditionally been based on conservative, empirical rules.
What are the factors affecting the load-carrying capacity of socket piles?
The safe load-carrying capacity of the socket piles will depend on a number of factors in relation to the behaviour of the rock mass: The properties of the rock . The presence of fractures in the rock . The size and spacing of any fractures. The degree of weathering of fractures. The presence of any soil within fractures.
What is the difference between H-piles and steel piles?
Because H-piles can resist hard driving, they are able to penetrate soils where other types of piles cannot. Steel H-piles are produced according to ASTM specifications, and can be produced with improved corrosion performance for salt water splash zones. This grade may be referred to as “weathering” type steel.
