Precise positioning method for main tower cable guide pipe of cable-stayed bridge
The invention relates to the technical field of stay cable construction, in particular to a precise positioning method for a cable guide pipe of a main tower of a cable-stayed bridge. Comprising the following steps of (1) establishment of a space rectangular coordinate system, (2) establishment of a mathematical model for cable conduit positioning, (3) field preparation, (4) cable conduit positioning plate preparation, (5) technology preparation, (6) control point combined measurement and rechecking, (7) coarse positioning, (8) fine adjustment, (9) cable conduit cutting and fine adjustment after cutting, and (10) remeasurement after mold closing and finished product rechecking. According to the method, a three-dimensional space coordinate method of a space linear equation is used, and a high-precision total station is matched to carry out installation and accurate positioning on the anchoring end and the tower outlet end of the cable guide pipe. A space linear equation of each cable conduit is programmed in advance, data checking of measured values and theoretical values can be carried out at any time, and accurate position adjustment is achieved. Operation is easy and convenient, application is convenient, labor intensity is low, positioning precision is high, safety and reliability are achieved, work efficiency can be improved, and construction cost is reduced.
本发明涉及斜拉索施工技术领域，更具体而言，涉及一种斜拉桥主塔索导管精密定位方法。包括以下步骤：(1)空间直角坐标系的建立、(2)索导管定位的数学模型、(3)现场准备、(4)索导管定位板准备、(5)技术准备、(6)控制点联测复核、(7)粗定位、(8)精调、(9)索导管切割与切割后精调、(10)合模后复测与成品复核。本发明运用空间直线方程的三维空间坐标法，配以高精度精密全站仪对索导管的锚固端、出塔端进行安装精确定位。提前将每一根索导管空间直线方程进行编程，可随时进行实测值与理论值的数据校核，实现精确的位置调整。操作简便，应用方便，劳动强度低，定位精度高，且安全可靠，能提高工效、降低施工成本。
