Method for positioning chimney-penetrating coal conveying trestle support
The invention relates to the field of civil engineering structures of power plants, in particular to a chimney-penetrating coal conveying trestle support positioning method which comprises the following steps: making a first inclined plane of a chimney-penetrating coal conveying trestle floor; the first inclined plane of the chimney penetrating coal conveying trestle floor is vertically and downwards translated by a certain distance, and a second inclined plane at the position of a trestle support is obtained; making an intersection line of a second inclined plane at the trestle support and the chimney gradual change cylinder, wherein the intersection line is an elliptic curve; four intersection points of the elliptic curve and the two straight lines are solved, and space coordinate values of the trestle support are obtained. By means of the method, the space coordinate points of the chimney-penetrating coal conveying trestle support can be correctly obtained, design deviation is avoided, smooth construction of the chimney-penetrating coal conveying trestle and normal use of the chimney-penetrating coal conveying trestle after production are ensured, and the adverse effect of initial installation stress on structural safety is avoided. Therefore, the technical problem that due to the fact that the positioning deviation of the chimney-penetrating coal conveying trestle is large, installation initial stress has adverse effects on structural safety can be solved.
本发明涉及电厂土建结构领域，尤其涉及一种穿烟囱输煤栈桥支座定位方法，包括以下步骤，做出穿烟囱输煤栈桥楼面的第一斜平面；将穿烟囱输煤栈桥楼面的第一斜平面垂直向下平移一段距离，获得栈桥支座处的第二斜平面；做出栈桥支座处的第二斜平面与烟囱渐变筒体的交汇线，该交汇线是个椭圆曲线；求出该椭圆曲线与两条直线的四个交点，获得栈桥支座的空间坐标值。本发明的方法可以正确获取穿烟囱输煤栈桥支座的空间坐标点，避免了设计偏差，确保了穿烟囱输煤栈桥的顺利施工，和投产后的正常使用，避免了安装初始应力对结构安全的不利影响。因此，本发明能够解决穿烟囱输煤栈桥的定位偏差大导致安装初始应力对结构安全产生不利影响的技术问题。
