新式引绳展放一牵七施工方法
摘要：
新式引绳展放一牵七施工方法，涉及一种引绳展放方法。目前，导引绳展放主要存在缺点是：来回牵引展放工序繁琐，在整个过程中需要多次高空移绳，高空作业量很大；双开门放线滑车需求数量多；工序繁琐，消耗时间。本发明包括以下步骤：1）牵引放绳，动力伞空中展放φ2迪尼玛绳作为施工用的初级引绳，按Φ2迪尼玛绳→Φ4迪尼玛绳→Φ8迪尼玛绳的顺序，人力牵引展放迪尼玛绳；按Ф8迪尼玛绳→□15防扭钢丝绳→□25钢丝绳顺序张力展放；张力展放时，利用一台大牵引机和两台大张力机进行一牵七张力展放导引绳，其中一台大张力机展放3根，另一台大张力机展放4根；2）走板过滑车及分绳。本技术方案劳动强度低，施工效率高。
摘要（英）：

A novel guide rope laying one-pull-seven construction method relates to a guide rope laying method. At present, the guide rope laying mainly has the disadvantages that back-and-forth traction laying process is tedious; a plurality of high-altitude rope moving is needed in the whole process and the high-altitude construction amount is large; and the process is tedious and is time consuming. The novel guide rope laying one-pull-seven construction method comprises the following step: 1) pulling and laying ropes: a powered parachute aerially lays a [phi]2 Deenyma rope serving as a primary guide rope for construction, and the Deenyma ropes are dragged and laid manually in the order of [phi]2 Deenyma rope-[phi]4 Deenyma rope-[phi]8 Deenyma rope; the ropes are in tension laying in the order of [phi]8 Deenyma rope-[phi] 15 anti-twisting steel wire rope-[phi]25 steel wire rope; during tension laying, a large tractor and two large tension machines are utilized to carry out guide rope one-pull-seven tension laying, wherein one large tension machine lays three ropes and the other large tension machine lays four ropes; and 2) moving plate passing through a pulley and rope branching. With the technical scheme, the labour intensity is low and the construction efficiency is high.
