浅谈水浮拆除河涌内大直径钢管施工

The Float Removing Construction of a Large Diameter Steel Pipe in the River

按照以往过江河大直径钢管的拆除施工经验,一般采用围堰法或打捞法,但施工成本均非常高。随着对河涌治理要求的不断严格,传统的施工方法已很难满足河涌管理部门的要求,因此对于一般河涌宽度在50m以下的过河涌大直径钢管,可采用水浮拆除施工方法,具有经济、快速和环保的优点。

Judging from previous construction experience of demolition for large diameter steel tube passed over the river,it is usually used the costly cofferdam method or salvage law construction.But it is difficult to meet the strict requirements of water treatment for creek management formulated by the river administrative department.The large diameter steel pipe can be adopted the float removing method in water for the inland river below 50m in width in the result of rapid economic and environment protection.
