Utility tunnel pipeline buttress assembly type installation method
The invention discloses a comprehensive pipe gallery pipeline buttress assembly type installation method, and belongs to the technical field of municipal comprehensive pipe gallery construction.The method comprises the specific steps that a pipeline buttress is prefabricated, and a reserved hole channel is preset in the pipeline buttress; a reserved sleeve is arranged on a pipe gallery bottom plate and connected with a fixed anchor bar; hoisting the prefabricated pipeline buttress into the pipe gallery, pre-burying a hoisting ring by utilizing a top plate of the pipe gallery, hoisting the pipeline buttress by adopting a chain block, aligning a reserved hole channel with a fixed anchor bar and lowering, reserving a certain gap at the bottom of the pipeline buttress, arranging a grouting template at the periphery of the lower part for sealing, sealing by utilizing a rubber ring, and presetting an inspection hole; and finally, filling the grouting space with a compensation shrinkage type grouting material. Compared with the prior art, the use amount of on-site turnover materials and small machines and tools is reduced, the safety risk is reduced, the construction efficiency is improved, the labor input is reduced, and the positioning precision of the embedded part is improved; and through batch prefabrication of the pipeline buttresses, the appearance quality of buttress concrete can be improved, errors are reduced, and the cost is greatly saved.
本发明公开一种综合管廊管道支墩装配式安装方法，属于市政综合管廊施工技术领域，具体步骤包括，预制管道支墩，并在其中预设预留孔道；在管廊底板上设置预留套筒，并连接固定锚筋；再将预制好的管道支墩吊入管廊内，利用管廊顶板预埋吊环，采用手拉葫芦将管道支墩吊起，将预留孔道对准固定锚筋并下放，管道支墩底部预留一定间隙，下部四周设置灌浆模板封闭，利用橡胶圈密封，并预设检查孔；最后采用补偿收缩型灌浆料填充灌浆空间。本发明与传统技术相比，减少现场周转材料和小型机具的使用量，降低了安全风险，提高了施工效率，降低劳动力投入，提高预埋件定位精度；通过管道支墩的批量预制，可提升支墩混凝土外观质量，减小误差，大幅节约成本。
