Cable bridge main cable surface wrapping and painting door, in the clamp position by caulking to ensure air tightness, some details of defects, protective coating system damage or caulking defects, leading to the main cable cannot remain completely airtight. The main cable surface is wrapped with steel wire, round steel wire and S steel wire winding, but all must be coated with surface protection, in order to complete the sealing of the main cable. Changes in temperature and stress of cable clamp fluctuation under the action of the main cable and cable clamp between the winding material will occur relative deformation, round wire winding wire between each independently, the deformation of dispersed in wire, coating will lead to fatigue cracking; S shaped steel wire wound by tongue bite, the deformation will accumulate to transfer cable clamp caulking, causing breakage leakage. The composite winding method of the invention adopts the material of the waveform section to be winded, and the soft layer material is sealed between the overlapped wave layers to perform certain winding tension to achieve the self sealing of the winding material. The invention is applicable to the technical field of main cable dehumidification.
【技術實現步驟摘要】
一種利于除濕的纏繞方法
本專利技術屬于索體防護
,特別是纜索橋主纜除濕
技術介紹
纜索橋主纜目前采用的干燥除濕防護,主纜表面有纏絲和涂裝防護,在索夾位置通過斂縫來保證氣密性,一些涂裝系統細節缺陷、防護破損或斂縫缺陷,導致主纜不能一直保持完全氣密,主纜與外界之間仍會有少量的空氣交換。主纜表面纏繞用鋼絲主要有圓形鋼絲和S形鋼絲,沿主纜圓周向纏繞成螺旋狀。纏繞時施以一定的張力,但都必須配合表層涂裝防護,才能完成對主纜的密封。在溫度變化、索夾間應力波動等作用下,索夾間主纜與纏繞會發生相對變形,圓形鋼絲纏繞每絲間獨立,該變形分散于絲間,會引起涂裝疲勞開裂;S形鋼絲纏繞采用企口咬合,該變形會累計傳遞到索夾斂縫處,造成斂縫破損漏氣。
技術實現思路
本專利技術提供一種復合纏繞方法,纏繞物料不依賴涂裝獨立完成對主纜的密封。本專利技術的技術方案是采用波形斷面纏繞物料,在重疊波層間夾塞密封用軟質薄層材料,施以一定的纏繞張力,達到纏繞物料的自密封。由于采取以上技術方案,本專利技術具有以下有益效果:1.波形斷面纏繞物料能均分變形;2.重疊波層間夾塞密封用軟質薄層材料,纏繞物料能實現自密封;3.能減小或滅除變形的累計傳遞,使索夾處斂縫不致破損漏氣;4.主纜底部水分存于波槽內,減少水分與鋼絲的直接接觸;5.螺旋纏繞時可形成連續通氣道,利于空氣縱纜向流動;6.纏繞物料如采用金屬,可引入陽極保護。附圖說明圖1是復合纏繞示意圖;圖中:1-波形斷面纏繞物料,2-軟質薄層材料,3-波形斷面纏繞物料。
