Negative-pressure vacuum supplementary grouting construction method for vertical prestressed pipeline of continuous beam
The invention relates to the technical field of building construction, in particular to a continuous beam vertical prestressed pipeline negative pressure vacuum supplementary grouting construction method. The method comprises the following steps: firstly, carrying out construction preparation, checking whether the types of materials are complete, whether the number meets the construction requirements, whether the quality meets the design requirements, and whether equipment and machines are complete and can operate normally, then carrying out grouting preparation, installing a grouting module according to the construction requirements, then carrying out vacuum pumping, and carrying out vacuum degree detection. The method comprises the following steps of: cleaning water and impurities in a pipeline, preparing slurry, starting formal vacuumizing and grouting, vacuumizing to a designed negative pressure value, closing a vacuumizing valve after the designed negative pressure value is reached, opening a grouting valve, closing the grouting valve after pressure maintaining is finished, and finally removing a vacuum pump and grouting equipment to finish grouting. According to the grouting pipe, grout can smoothly flow in the grouting pipe, the phenomenon of difficult grouting is avoided, and grouting operation is facilitated.
本发明涉及建筑施工技术领域，具体涉及一种连续梁竖向预应力管道负压真空补充注浆施工方法；首先进行施工准备，检查物料种类是否齐全，数量是否满足施工要求，质量应符合设计要求，检查设备和机具是否齐备，是否可以正常运转，然后进行压浆准备，根据施工要求安装注浆模块，随后试抽真空，进行真空度检测，然后对管道内水及杂物清除干净，接着进行浆液配置，开始正式抽真空注浆，抽真空至设计负压力值，到达设计压力值后，关闭抽真空阀门，打开注浆阀门，在保压结束后关闭注浆阀门，最后拆除真空泵及注浆设备，压浆结束，通过上述方式，实现了能够使浆液在压浆管内流通顺畅，不会出现注浆困难的现象，利于进行压浆操作。
