Multi-tower-limb bridge tower pier air control network laying method
The invention relates to the technical field of bridge construction measurement, in particular to a multi-tower-limb bridge tower pier air control net laying method which comprises the following steps that air total stations installed on the inner walls of the top ends of all tower limbs of a bridge tower pier are used for downwards and vertically setting points to a bearing platform; measuring a plumbing point of each aerial total station to obtain an observation coordinate of each plumbing point; establishing an aerial geodetic polygon net by using the center of each aerial total station, and measuring by using the aerial total stations to obtain the observation side length between every two vertexes of the aerial geodetic polygon net; and according to the observation coordinate of each plumbing point and the observation side length between every two vertexes of the aerial geodetic polygon net, determining the coordinate of the aerial total station, and establishing the bridge tower pier aerial control net. The problems that in the prior art, a first-lower-first-upper-second method is not suitable for multi-tower-limb bridge tower pier control point measurement, procedures are complicated, and measurement efficiency is extremely low can be solved.
本发明涉及桥梁施工测量技术领域，具体涉及一种多塔肢桥塔墩空中控制网布设方法，该多塔肢桥塔墩空中控制网布设方法，包括以下步骤：利用安装在桥塔墩各个塔肢顶端内壁的空中全站仪向下铅垂投点到承台上；对各个空中全站仪的投点进行测量，得到各个投点的观测坐标；以各个空中全站仪的中心建立空中大地多边形网，利用空中全站仪测量，得到空中大地多边形网每两个顶点之间的观测边长；根据各个投点的观测坐标和空中大地多边形网每两个顶点之间的观测边长，确定空中全站仪的坐标，建立桥塔墩空中控制网。能够解决现有技术中采用“先下后上”的方法不适应于多塔肢桥塔墩控制点测量，存在工序繁杂，以及测量效率极低的问题。
