14、Foreword (This Foreword is not a part of American National Standard A10.19-2017.) This standard is one of a series of safety standards that have been formulated by the Accredited Standards Committee on Safety in Construction and Demolition Operations, A10. It is expected that the standards in the A1

15、0 series will find a major application in industry, serving as a guide to contractors, labor and equipment manufacturers. For the convenience of users, a list of existing and proposed standards in the A10 series for Safety Requirements in Construction and Demolition Operations follows. A10.1 Pre-Pro

16、ject it contains a well or recess on its top for cushion material and for seating an anvil (if used). Its bottom is formed to accept a specific shape of pile, along with its cushion (if used). Its outside incorporates a lug or insert slot for attachment to the lead system. A driving head is also ref

17、erred to as an anvil block, bonnet, cap, helmet, follow cap, rider cap or shield. 3.14 Fall. A measure of a rigging components vertical length. 3.15 Fall Zone. The area (including but not limited to the area directly beneath the load) in which it is reasonably foreseeable that partially or completel

18、y suspended materials could fall in the event of an accident. 3.16 Follower. An extension used between a pile and pile hammer that transmits blows to the pile when the pile head is either below the reach of the pile hammer (below the guides/leads) or under water. A follower is commonly a section of

19、pipe or “H” pile with connections that match both the pile hammer and the pile being driven. 3.17 Ground Conditions. The condition of the ground as it relates to its adequacy for support of pile driving equipment and stored materials, including the grounds slope, compaction, and firmness. 3.18 Guide

20、 Rail. That part of the pile hammer leads which forms a pathway for the pile hammer and which consists of parallel members that mate with the side channels of the pile hammer. Guide rails are also referred to as “Lead Rails” or “Hammer Guides”. 3.19 Hammer, Drop Impact. A pile hammer (also referred

21、to as “Drop Hammer” or “Hair Pin Hammer”). For purposes of this standard, there are four types of drop impact hammers: 1) Cable Operated Drop Hammer. A drop impact (pile) hammer consisting of a machine lifted weight which is allowed to free fall to drive the pile. 2) Steam Drop Hammer. A drop impact

22、 hammer consisting of a cylinder which acts as the falling weight which is lifted by steam pressure. 3) Hydraulic Drop Hammer. A drop impact hammer consisting of a segmented ram, which is lifted by hydraulic pressure to a pre-set height. The pile hammer is then allowed to fall onto a driving cap. Th

23、e weight and height of the ram can be varied to suit site conditions. 4) Diesel Drop Hammer. A drop impact hammer consisting of a cylinder, which acts as the falling weight, which is operated by compression-ignition as a result of the weight falling and compressing the contents of the cylinder. 3.20

24、 Hammer Energy. The amount of potential energy available to transfer from a pile hammer to a pile, usually measured in foot-pounds. 3.21 Kicker. The strut between the crane and the pile leads (also referred to as a “Spotter”). 3.22 Leads. Two parallel members of a wooden or steel frame for guiding t

There are three types of leads: 1) Fixed Leads. Leads which are fixed to a pile rig at its

26、 top and bottom. 2) Swinging Leads. Leads which are supported at the top by a cable attached to a pile rig. 3) Semi-Fixed or Telescopic Leads. Leads which are allowed to translate vertically in relation to a pile rigs boom tip. 3.23 Lifting Bail. Rigging apparatus used to attach a crane hoist line t

27、o the pile driving equipment. 3.24 Mandrel. A full-length steel core set inside a thin shell casing for cast-in-place concrete piles.

A concrete, steel, wood, synthetic plastic or aluminum element which is driven, pressed or otherwise introduced into the so

29、il, usually to carry a vertical load or to provide lateral support. 3.28 Pile Butt. A term commonly used in connection with timber piles. The upper or larger end of a pile closest to the pile hammer. 3.29 Pile Contractor. A contractor whose scope of work on a particular project includes the installa

30、tion and/or extraction of piles. 3.30 Pile Gate. A hinged section attached to the pile leads, at the lower end, which serves to keep the pile within the framework of the pile leads. 3.31 Pile Hammer. A device, which develops and expends the energy used to drive piles, the two main parts of which are

31、 the ram and the anvil. Also referred to as a “Pile Driver Hammer”. Pile hammers can be powered by various energy sources such as diesel, compressed air, steam, hydraulic and gravity. 3.32 Pile Head. The upper end of a pile. 3.33 Pile Rig. The crane or other type of equipment used to support the lea

32、ds and pile driving assembly during a pile driving or extraction operation. 3.34 Power Plant. A prime mover consisting of an engine and generator, hydraulic pump or compressor used to provide electricity, hydraulic power or compressed air to portable construction equipment such as a vibratory pile h

33、ammer/ extractor or impact pile hammer/extractor. 3.35 Prefabricated Pile Tips. An attachment to the end of a precast concrete pile, a steel pile, a timber/wood pile to assist the pile penetration through the strata and to assist in the prevention of damage to the pile during driving 3.36 Pre-Drilli

34、ng. A process where a hole is drilled with a continuous flight auger or a wet rotary bit to remove some soil or loosen the strata when driving the pile will displace the upper soil enough to push adjoining piles out of the proper position or limit vibration in the upper layers. 3.37 Project Construc

35、tor. A person, firm or corporation, i.e. the construction manager, general contractor, prime contractor or other entity, as designated in the project documents, responsible for supervising and controlling all construction work performed on the project.
