浅谈钢管顶管轴线测量

Introduction to Steel Pipe Jacking Axis Line Measurement

在市政管道施工中,钢管顶管施工是一种常用的方法,广泛应用于各类管线埋设工程中。在顶管施工之前进行必要而精确的施工测量,对确保施工质量达到设计要求具有十分重要的意义。本文介绍了两种钢管顶管轴线测量的常用方法,和三种顶管轴线偏差测量方,最后提出了一些提高顶管测量精度和施工质量的措施。

In the municipal pipeline construction, the steel pipe jacking a commonly used method, and is widely used in various pipeline laying project. Necessary and accurate measurement before the pipe jacking construction of the, ensure the construction quality, is of great importance to meet the design requirements. This article introduces the common method pipe jacking axis measurement, combined with two steel pipe jacking in the project encountered, the jacking axis deviation cases, on top of the tube axis deviation measurement methods are discussed. Then the author puts forward some improving measures accuracy and quality of construction pipe jacking.
