摘要

为了解决长距离大口径顶管在富水流砂卵石地层环境下的掘进顶力过大问题，以西气东输黄河顶管工程为例对注浆减阻进行研究。主要从注浆设备选取、润滑泥浆配比、注浆压力控制和注浆量控制等方面控制好浆液，确保注浆减阻效果，降低钢管与周围砂层的摩擦阻力，从而降低推进顶力，顺利达到长距离掘进的施工目标。

Abstract

Longdistance largediameter pipe jacking in waterrich quicksand cobble ground needs huge jacking force. In the construction of Yellow River Crossing Pipe Jacking Works on WestEast Natural Gas Transfer Project, the jacking resistance is reduced by means of grouting. The resistance reduction effect is guaranteed by means of proper grouting equipmentn, proper grout slurry mixing proportion, proper grouting pressure control and proper grouting volume control. In the end, the resistance between the steel pipes and the surrounding sand ground is reduced, the jacking force needed is lowered and successful longdistance pipe jacking is realized. 

Key words： waterrich quicksand cobble ground; pipe jacking; grout slurry; resistance reduction by grouting
