Thixotropic slurry drag reduction optimization construction method for long-distance pipe jacking
The invention discloses a thixotropic slurry drag reduction optimization construction method for long-distance pipe jacking. The thixotropic slurry drag reduction optimization construction method comprises the following specific steps that 1, the thixotropic slurry proportion is determined; 2, a grouting hole and a grout supplementing hole are formed in a pipeline connected with a jacking pipe; 3,jacking construction and grouting construction are conducted synchronously; 4, a grout supplementing technology and a grouting technology are combined for construction; and 5, a jacking operation program without an intermediate jacking station and a jacking operation program of the intermediate jacking station are divided until pipe jacking is completed. By controlling the grouting ratio in the earlier stage and arranging the grouting hole and the grout supplementing hole, the resistance during advancing can be optimally reduced; a targeted construction scheme is provided by judging whether the intermediate jacking station is arranged or not, so that the accuracy of pipe jacking connection is guaranteed; through measurement control, it is guaranteed that the drilling angle and direction meet the design requirements; and by monitoring, comparing and analyzing the actual grouting amount and jacking force, the design of a grouting scheme and jacking force jacking work can be further standardized and perfected.
本发明公开了一种用于长距离顶管的触变泥浆减阻优化施工方法，具体步骤如下：步骤一、确定触变泥浆配比；步骤二、连接顶管的管道上设置注浆孔和补浆孔；步骤三、顶进施工与注浆施工同步进行；步骤四、将补浆技术与注浆技术结合施工；步骤五、分为无中继间时顶进操作程序和中继间顶进操作程序，直至顶管完成。本发明通过前期对注浆配比的控制，以及设置的注浆孔和补浆孔，有利于最优化降低前进时的阻力；通过中继间的设置与否，给出了针对性的施工方案，保证顶管连接的准确性；通过测量控制，利于保证钻进角度和方向满足设计要求；通过实际注浆量和顶力的监测对比分析，可进一步规范和完善注浆方案和顶力顶进工作的设计。
