Assembling and Moving Technology of On-Water Work Platform in Pile Sinking by Water Jetting
摘要
Abstract
It introduced the technical index and operation task of on-water work platform in pile sinkinf by water Jettinf. The assemblinf site of the platform was situated in the scope of 200 m of the upper reaches of pile sinkinf construction site. Near-shore floatinf body should be the first to be moved in water and anchored,then other 5 floatinf bodies were moved into water in turn and anchored. Assemblinf directional line and water front form an anfle of 10°~15°;on-water movinf of work platform was throufh pushinf by barfe lyinf in the lower reaches,looseninf the anchor on the shore in the upper reaches and the wire rope fasteninf on the anchor in the river. The distance between the work ship board and enfineerinf location center should be 0. 6~0. 7 m;anchorinf measure with splayed-shape pattern should be taken in operatinf period in workinf site to ensure the safety and stability of platform under complicated workinf conditions. The power of the platform movinf alonf enfineerinf position line was mainly the im-pact force of water stream and tension of windinf enfine. Slidinf speed control and position adJustment mainly relied on adJustinf the moorinf rope in the corner of work platform. Besides,announcements of on-water workinf were showed clearly.关键词
