水工地下大洞径断面开挖轮廓线监理检测

The Supervision and Detection of Contour Lines on Radial Sections of Underground Caverns on Water Conservancy Projects

隧洞断面开挖放样是直接为施工服务的,而检测工作是监理人员必须的工作。监理人员结合测量仪器和计算工具,依据具体的施工图纸进行隧洞断面开挖检测验收,检查开挖断面尺寸,核定超挖部分回填混凝土量。本文就海原县石峡口水库水工建筑物地下大洞径隧洞断面开挖后的检测计算方法作了论述,找出了解决该问题的办法,希望为类似工程监理及施工工作起到抛砖引玉的作用。

With direct service of loftings work on tunnel radial sections,the checkups and measurements are bound to be fulfiled by supervisors who should conduct both detection and acceptance check on tunnel radial Ssections,review the sizes of excavating sections and examine the overexcavated volumes of backfill concrete according to concrete construction drawings through combination of measuring apparatus and computing equipments.This article expounds on methods of calculation and detection work on the radial sections construction in Shixiakou Reservoir of Haiyuan county as well as on some ways out of problems in the process of working so as to be a good unprecedented instance guiding similar supervision tasks and constructions.
