    • A bridge replacement method is disclosed. The bridge includes a deck supported by a pair of abutments, each abutment having wing walls. The deck is removed, footings are cast in holes dug behind each abutment and a pier is provided on each footing. Substantially parallel and coplanar cambered beams are provided. Each beam spans between and is supported by the piers. A brace assembly reinforces the beam camber. On each adjacent pair of beams, precast deck elements are placed, such that each element of said plurality spans the beam pair, to define at least transverse gaps between the elements and put the upper surfaces of the elements in compression in a transverse direction. The gaps are grouted. After grout curing, the brace is adjusted to reduce the beam camber and cause the upper surface of the elements to also be put into compression in a direction parallel to the beams.

    • A pliers-type insulation stripping tool includes an adjusting device for adjusting the cutting profile provided by the knife edges of a stack of parallel lamellar cutting blades pivotally connected at one end with a knife holder for independent pivotal movement about a first pivot axis parallel with the tool handle pivot axis. The adjusting device comprises a cylindrical support member that is mounted in the associated knife holder for rotation about an axis parallel with the first pivot axis. The circumferential surface of the support cylinder includes a plurality of segments that are selectively engaged by flat portions of the cutting blades, thereby to define different cutting profiles, respectively. The knife holder is connected for longitudinal displacement on one the clamping jaws of the tool handles, thereby to remove a severed length of the insulation layer from the insulated conductor.
    • 钳式绝缘剥离工具包括调节装置,用于调节由平行层状切割刀片的刀片边缘提供的切割轮廓,所述平行片状切割刀片的一端可枢转地连接在刀架上,用于独立的枢转运动,围绕与 刀柄旋转轴。 调节装置包括圆柱形支撑构件,其被安装在相关联的刀架中,用于围绕平行于第一枢转轴线的轴线旋转。 支撑圆筒的圆周表面包括多个分段,其分别选择性地与切割刀片的平坦部分接合,从而分别限定不同的切割轮廓。 刀架连接用于工具把手的一个夹爪上的纵向位移,从而将绝缘层与绝缘导体断开。
