借助GPS全球卫星定位系统，松浦大桥百米高空的主塔上塔柱施工精度大大提高，其误差可控制在10毫米之内。记者从松浦大桥建设指挥部获悉，目前松浦大桥主塔已经升至100米，百米以上施工也创下哈尔滨市江上建筑施工最高纪录。

　　据了解，松浦大桥上塔柱部分是斜拉桥拉索区，共有108根悬索集结于此，该节段所涉及的环向预应力极大、索导管安装、钢锚梁定位齿块的施工精度要求极高。据初步测算，该节段要承载斜拉索上万吨的核载拉力，是全塔受力最大的部分。松浦大桥指挥部对斜拉桥拉索区环向预应力、索导管安装等施工采取GPS全球卫星定位系统进行空间定位，选择无风、无阳光的清晨和傍晚进行测量，每天测量两次，保证百米高空任何尺寸误差在10毫米以内，确保施工精度。

　　据介绍，自8月23日中塔柱合龙后，目前松浦大桥主塔已升至平台上101.22米，这标志着工程最艰难的施工将在百米上空全面展开。松浦大桥主塔塔柱整体高度为160米，目前主塔塔柱百米以上还有60米的上塔柱施工。

With GPS global satellite positioning system, Matsuura Bridge, 100 meters above the ground on the main tower Pylon construction accuracy has greatly improved the error can be controlled within 10 mm. Matsuura The reporter learned from the bridge construction headquarters was informed that currently the main tower of the bridge Matsuura has risen to 100 meters, 100 meters above the construction has also reached the river in Harbin construction record.


It is understood that part of Matsuura Pylon cable-stayed bridge cables district, a total of 108 cable assembly here, the segments involved in a great ring pre-stress, cable conduit installation, the steel beam positioning gear block anchor Construction of very high precision. According to preliminary estimates, the segment of cable-stayed to carry tens of thousands of tons of nuclear set pull, the whole tower of the largest part of the force. Matsuura Bridge, Central Command area of cable-stayed bridge to prestressed cables, cords and duct construction and installation to take GPS global satellite positioning system for spatial orientation, select no wind, no sun in the morning and evening measurements, measured twice a day, any size guarantee 100 meters altitude error of less than 10 mm to ensure the accuracy of the construction.


It is reported that since August 23 Japan-China Pylon closure, at present, the main tower of the bridge Matsuura has risen to 101.22 meters platform, which marks the most difficult construction projects will be over 100 meters in full swing. Matsuura Bridge Tata column overall height of 160 meters, 100 meters above the present main Tata columns are 60 meters on the Pylon construction.
