Rapid dismantling construction method for large-dip-angle variable-cross-section ultrahigh cable bent tower upward climbing surface formwork
The invention provides a large-dip-angle variable-cross-section ultrahigh cable tower upward-climbing surface formwork rapid dismantling construction method which comprises the steps that S1, after a first section of a middle-upper tower column is maintained in place, an upper truss of a hydraulic climbing formwork is hoisted and dismantled through a tower crane; s2, the middle of a lower hanging frame of the hydraulic creeping formwork is connected with a cable bent tower through a first chain block, and a guide rail is dismantled; s3, a tower crane and a safety sling are used for conducting auxiliary hoisting on the hydraulic creeping formwork; s4, the lower climbing cone support and the hydraulic oil pump are dismantled; s5, the first chain block is released by a certain length, a plug pin of the upper climbing cone support is removed, and the hydraulic climbing formwork is lifted through the tower crane to be separated from the upper climbing cone support; s6, the tower crane is used for slowly moving the hydraulic creeping formwork, the first chain block is slowly released, so that the hydraulic creeping formwork is separated from the cable bent tower, the safety sling and the first chain block are removed, and the hydraulic creeping formwork is lowered; and S7, the upper climbing cone support is dismantled. The safety of the construction process can be guaranteed, operation is convenient, the construction progress can be accelerated, and the construction cost is reduced.
本发明提供一种大倾角变截面超高索塔仰爬面模板快速拆除施工方法，包括：S1、中上塔柱的第一节养护到位后，利用塔吊吊装拆除液压爬模的上桁架；S2、利用第一手拉葫芦将液压爬模的下挂架中部与索塔连接，拆除导轨；S3、利用塔吊以及安全吊带对液压爬模进行辅助吊装；S4、拆除下爬锥支座以及液压油泵；S5、释放第一手拉葫芦一定长度，拆除上爬锥支座的插销，利用塔吊上提液压爬模，使液压爬模脱离上爬锥支座；S6、利用塔吊缓慢移动液压爬模，并缓慢释放第一手拉葫芦，使得液压爬模与索塔脱离，解除安全吊带与第一手拉葫芦，下放液压爬模；S7、拆除上爬锥支座。本发明能够保证施工过程的安全性，并且操作方便，有利于加快施工进度、降低施工成本。
