Precise positioning method for steel tower
The invention relates to the technical field of bridge construction measurement, in particular to a steel tower precision positioning method which comprises the following steps: matching and butting a lower end ring opening of a to-be-mounted steel tower section with an upper end ring opening of a mounted steel tower section in the horizontal direction; the feature points are observed from at least three observation stations, and the known three-dimensional coordinates of the observation stations and the feature points are combined to obtain side length correction coefficients between the feature points and the corresponding observation stations; observing the position measuring point from a measuring station point with the same matched feature point of the position measuring point, and correcting the coordinate of the position measuring point according to the side length correction coefficient to obtain the difference forward intersection coordinate of the position measuring point; and according to the deviation values of the theoretical coordinates of all the position measuring points and the difference forward intersection coordinates, perpendicularity adjustment is carried out on the to-be-installed steel tower section, and the to-be-installed steel tower section is made to be in place. The problems that in the prior art, an ultrahigh concrete bridge tower pier construction measurement method is not suitable for ultrahigh steel tower installation positioning measurement, and a traditional steel tower installation measurement method is low in measurement precision can be solved.
本发明涉及桥梁施工测量技术领域，具体涉及一种钢塔精密定位方法，该方法包括以下步骤：将待安装钢塔节段的下端环口与已安装钢塔节段的上端环口在水平方向匹配对接；特征点从至少三个测站点观测，结合测站点和特征点的已知三维坐标，得到特征点到对应测站点之间的边长改正系数；从位测点相匹配特征点相同的测站点观测该位测点，根据边长改正系数对位测点的坐标进行修正，得到该位测点的差分前方交会坐标；根据所有位测点的理论坐标与差分前方交会坐标的偏差值，对待安装钢塔节段进行垂直度调整，使待安装钢塔节段就位。能够解决现有技术中超高混凝土桥塔墩施工测量方法不适合超高钢塔安装定位测量，传统钢塔安装测量方法存在测量精度低的问题。
