Prestress tension duct grouting process
The invention discloses a pre-stress tension duct grouting process and grouting equipment, and relates to the technical field of grouting, the pre-stress tension duct grouting process comprises the following steps: S1, preparation work; s2, trial vacuumizing is carried out; s3, stirring the slurry; step S4: grouting; and S5, cleaning: cleaning the mudjack. According to the method, original air and water in the hole channel are removed through the positive and negative pressure difference between the grouting pumps in the hole channel, meanwhile, bubbles and redundant free water mixed in cement paste are removed, and the fullness and compactness of the paste in the hole channel can be improved.
本发明公开了一种预应力张拉孔道压浆工艺及压浆设备，涉及压浆技术领域，包括步骤S1：准备工作；步骤S2：试抽真空；步骤S3：拌浆；步骤S4：压浆；步骤S5：清洗：清洗压浆。本发明通过采用孔道内的压浆泵之间的正负压力差，将孔道中原有的空气和水被清除，同时，混夹在水泥浆中的气泡和多余的自由水被排除，可提高孔道内浆体的饱满和密实度。
