Lofting method for bridge cast-in-place pile
The invention relates to the technical field of cast-in-place pile surveying and setting-out, in particular to a lofting method for a bridge cast-in-place pile. The lofting method for the bridge cast-in-place pile comprises the following steps that a plurality of reference point groups consisting of first reference points a and second reference points b are surveyed and mapped on the ground of a construction site; a first positioning nail is mounted at the top of a first reference pile corresponding to the first reference point a; a second positioning nail is mounted on the top of z second reference pile corresponding to the second reference point b; the first positioning nail of the first reference point a and the second positioning nail of the second reference point b are connected through a wire rope, and the center point of a cast-in-place pile c is calibrated at the position, away from the first positioning nail by the preset distance d, on the wire rope; the actual distance d' between the first positioning nail of a first reference point a and the center point of the cast-in-place pile c is measured, and the theoretical distance d is compared with the actual distance d' to judge whether lofting is qualified or not. According to the lofting method for the bridge cast-in-place pile, it is guaranteed that lofting work is timely and accurate.
本发明涉及灌注桩测量放线技术领域，尤其涉及一种桥梁灌注桩放样方法。该桥梁灌注桩放样方法，在施工现场的地面测绘多组由第一参照点ai和第二参照点bi组成的参照点组。对应第一参照点ai在第一参照桩的顶部安装第一定位钉；对应第二参照点bi在第二参照桩的顶部安装第二定位钉；使用线绳连接第一参照点ai的第一定位钉与第二参照点bi的第二定位钉，在线绳上的距离第一定位钉预定距离dij处标定灌注桩cij的中心点，量取第一参照点ak的第一定位钉与灌注桩cij的中心点之间的实际距离dkij’，将理论距离dkij与实际距离dkij’相比较，以判断放样是否合格。该桥梁灌注桩放样方法，保证放样工作及时且精准。
