Extension method for outer ladder stand of fan foundation
The invention discloses a fan foundation outer crawling ladder extension method in the technical field of engineering construction assistance, which comprises the following steps: S1, calculating the height from a butt joint hole of an original crawling ladder to the ground according to flood control requirements; s2, the distance L2 between an original crawling ladder butt joint hole and the bottom face of a crawling ladder vertical rod is obtained, and the height L3 from the lowest point of a newly-welded crawling ladder to the ground is preset; s3, a newly-welded crawling ladder is welded on site, the vertical distance of the newly-welded crawling ladder is L1-L2-L3, the inclination angle alpha of the original crawling ladder is obtained, and the transverse distance of the newly-welded crawling ladder is (L1-L2-L3)/tan alpha; and S4, a first ladder stand foundation is erected below the ladder stand vertical rods of the original ladder stand, a second ladder stand foundation is erected below the lowest position of the original ladder stand, one end of the newly-welded ladder stand is erected on the second ladder stand foundation, and the other end of the newly-welded ladder stand is erected on the third ladder stand foundation. The method for prolonging the crawling ladder is provided to solve the problems that a draught fan foundation is high and an original crawling ladder cannot be directly applied, and the method is implemented through field direct construction to solve the problems that time and transportation cost are high due to the fact that the crawling ladder is redesigned and produced.
本发明公开的是工程施工辅助技术领域的一种风机基础外爬梯延长方法，包含,S1、根据防洪要求计算原爬梯对接孔到地面的高度；S2、获取原爬梯对接孔到爬梯竖杆底面之间的距离L2，预设新焊爬梯最低点到地面的高度L3；S3、现场焊接新焊爬梯，新焊爬梯的竖向距离为L1‑L2‑L3，获取原爬梯倾角为α，新焊爬梯横向距离为(L1‑L2‑L3)/tanα；S4、在原爬梯的爬梯竖杆下方搭设第一爬梯基础，在原爬梯的最低位置下方搭设第二爬梯基础，新焊爬梯一端搭设在第二爬梯基础上，另一端搭设在第三爬梯基础上。提供一种延长爬梯的方法，以解决风机基础高，原爬梯不能直接适用的问题，通过现场直接施工进行实施，以解决重新设计生产爬梯带来的时间和运输成本高的问题。
