A pile splice joins two segments of a driven pile, using either a weld (typical for H beams), grout or mechanical means (typical for precast concrete piles). Pile splices enable the use of shorter segments, which allows for driving piles in low-headroom situations such as under bridges or inside buildings. [ 1 ]
The pile hammer was a construction that allowed a heavy weight to fall on the top of the pile. Each pile wore a "pile shoe" tip made of iron. A group so hammered was called a "straddle" and atop as well as surrounding the straddle was a pile supported platform called a "starling" which was filled with rubble before the pier and bridge deck were ...
Splicing timber piles is still quite common and is the easiest of all the piling materials to splice. The normal method for splicing is by driving the leader pile first, driving a steel tube (normally 60–100 cm long, with an internal diameter no smaller than the minimum toe diameter) half its length onto the end of the leader pile.
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
A girder bridge is a bridge that uses girders as the means of supporting its deck. [1] The two most common types of modern steel girder bridges are plate and box. [citation needed] The term "girder" is often used interchangeably with "beam" in reference to bridge design.
The most notable bridge failure due to gusset plates is the collapse of I-35W Mississippi River bridge in Minneapolis, Minnesota on August 1, 2007. Investigators found that the bridge had 16 under-designed gusset plates that fractured and ripped, and that the remaining gusset plates were properly designed and remained intact.
St. Tammany Parish Fire District #4, in an update around 9:50 a.m. Tuesday, had said fire units were dealing with an 11-vehicle crash on the southbound span of the Causeway Bridge. "As a result ...
Vibratory pile drivers are often chosen to mitigate noise, as when the construction is near residences or office buildings, or when there is insufficient vertical clearance to permit use of a conventional pile hammer (for example when retrofitting additional piles to a bridge column or abutment footing). Hammers are available with several ...
