Q. What are the safety aspects of pile driving equipment?
When a pile is guided into position, workers shall not put their hands or arms between the pile and the inside guide, but shall use a rope for guiding. A pile shall be provided with an iron ring or cap over the driving end to prevent grooming before the pile is hoisted.
Q. What is a driven cast in-situ pile?
Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended hollow steel or concrete casing into the ground and then filling it with concrete.
Q. What is pile driving in construction?
Pile driving is the process of installing a pile — a braced, structural column — into the ground without first excavating the area. These piles are driven, pushed or otherwise installed into the ground. As a construction method, pile driving has existed since before humankind was literate.
Q. What is the process of piling?
Piling is the process of inserting structural piles into the ground that will become the base of the building. Piles are required where soil and earth are performing poorly and are used to spread the load of a building and firm the ground.
Q. What does cast in situ mean?
Precast & cast-in-situ concrete are the product produced by casting concrete in a mould or formwork cured to get the strength of RCC elements. The cast-in-situ concrete is a standard concrete which is poured into the specific formwork on the site and cured to get the strength of RCC elements.
Q. What is insitu casting?
Cast-in-situ is the conventional method of concreting. In this Method concrete is prepared on the site and poured in formwork and then cured. It often requires more labours and even takes longer time. Precast concrete is the new method concreting used all over the world extensively.
Q. What is pile driving equipment?
equipment designed to align and hold piles in correct position and to drive the piles into the ground. Pile-driving equipment includes a weight-lifting device and a driver, which is usually mounted on a pile driver or on a truck, tractor, railroad platform, excavator, or crane hoist.
Q. How is a drive cast in situ pile constructed?
Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended hollow steel or concrete casing into the ground and then filling it with concrete. The 25mm thick heavy steel tube is driven with the end closed by a steel shoe.
Q. Can a concrete pile be made of driven cast?
Driven cast in-situ concrete piles can prove to be economic for sand, loose gravels, soft silts and clays, particularly when large numbers of piles are required. For small numbers of piles the on-site costs can prove expensive.
Q. Which is the best way to drive a concrete pile?
(iii) In case of very soft soil it is advisable to start driving the bore hole from outside to inside so that the soil gets restrained from flowing out during operation. (i) Driven cast-in-situ concrete piles are installed by driving a metal casing with a shoe at the tip/toe and displacing the material laterally.
Q. How is a steel tube driven in situ?
The 25mm thick heavy steel tube is driven with the end closed by a steel shoe. On reaching the required driving resistance, a full length cage is lowered in to the tube and filled with high slump concrete.
