2014-6-6Large-diameter bored piles in Hong Kong are mostly excavated either by hammer grabbing HG or reverse circu-lation drilling RCD. These two methods of installation en-able excavation of 3 m diameter piles to depths exceeding 70 m. To ensure the required pile penetration into the sapro-lite stratum it is common practice to sink a borehole

2020-6-12The installation process and methods of pile foundations are equally important factors as of the design process. Pile foundation installation methods are by pile hammer and boring by mechanical auger. To avoid damages to the piles during design installation Methods and installation equipment should be carefully selected. Ad Free
2019-2-11tom verticality of bored pilesdrilled shafts lled with water or slurry are ultrasonic methods. In ultrasonic methods the travel time of a sound wave travelling from shaft top to a sensor located at the shaft bottom is measured. Ultrasonic equipment currently employed includes the Koden the Sonicaliper. Both devices provide

2017-1-24The steps 1 and 3 are described in the following sections since the computation of settlements of bored piles foundation of superstructure is the main purpose of this work. Whiles the computation of carrying capacity of bored piles was comprehensive analyed in previous works 1112. 3. Physical and mechanical properties of the soil
Piles which causes the soil to be displaced vertically and radially as they are driven to the ground is known as Displacement piles. In case of Replacement piles the ground is bored and the soil is removed and then the resulting hole is either filled with concrete or a pre-cast concrete pile is inserted
The paper describes the estimating settlements of bored piles foundation on the site of the Elektrenai power plant Lithuania. The bored piles foundation supports equipment of the power plant consisting of the gas turbine the steam turbine and the generator
The pile embedment lengths range from 2 to 57 m and the pile diameters from 100 to 1220 mm. A performance analysis of the new SPT method is carried out with other prediction methods by using different criteria. The proposed method is suitable tool to practical design of bored piles due to their consistent results

Amir and Conrad W. Felice ABSTRACT Ultrasonic testing or crosshole logging CSL has become the primary means for judging the integrity of bored piles and barrettes
2020-6-12The diameter of bored piles can also be enlarged at the bottom up to three times the shaft diameter which enables an increase in the end-bearing resistance of the pile. End enlargements of up to 2-3 times the shaft diameter are possible in clays or soft rocks

Pile Classification Based On Construction Method On the basis of method of installation pile foundations can be divided into the following 6 types. Precast Driven Piles Driven Cast-in-situ Piles Bored Cast-in-situ Piles Bored Precast Piles Driven Steel Piles Driven Timber Piles 1. Precast Driven Piles These are usually of RCC or pre-stressed concrete and generally
2020-6-12Bored piles are cylindrical foundation elements 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. When installed in rows or in secant configuration they can form a supporting wall for an excavation pit or cut in the

Bored piles are a type of deep foundations which have been and are being widely used in construction engineering such as high-rise buildings bridges jetties and so on. Al-though bored piles have remarkable advantages over driven piles the quality of bored piles is frequently affected by many causes of imperfection which mainly come from the

Bored pile also called drilled shaft is a type of reinforced-concrete foundation that supports structures with heavy vertical loads.A bored pile is a cast-in-place concrete pile meaning the pile is cast on the construction site.This differs from other concrete pile foundations like spun pile and reinforced concrete square pile foundations which use precast concrete piles

They transfer high structural loads into deeper load-bearing soil strata form a supporting wall for an excavation pit or topographical change or seal off groundwater when tangenting or intersected
2020-6-12Pile Integrity Test. The integrity test is an essential part of quality control in either cast-in-place or pre-cast concrete. This is because the possible structural defects from pile installation such as cracks changes in cross-sections and the like can be detected by the use of this method
