Large-span swivel bridge swivel system rear sealing concrete grouting quality control method
The invention provides a large-span swivel bridge swivel system rear sealing concrete grouting quality control method. The method comprises the technical steps of 1, installing formworks between an upper bearing platform and a lower bearing platform; 2, installing a detection pipeline at a sealing area position close to four corners of the upper bearing platform, and installing a sensor in the pipeline as a means for checking process reliability and a quality supervision means; 3, preparing slurry; 4, performing quality detection on the slurry uniformly stirred in the step 3, and enabling the slurry to enter a storage tank through a filter screen after technical indexes of the slurry meet requirements specified by specifications; 5, pressing the grout checked in the fourth step into the sealing area through a grouting device; and 6, removing the mold after the strength of the slurry reaches a specified value; quality control is carried out through the vibration sensor, the grouting quality of post-sealing concrete meets the construction requirement, the safety and integrity of a bridge structure are effectively guaranteed, and loads on the upper portion of a bearing platform can be reasonably transmitted to a foundation part.
本发明提供了大跨度转体桥转体系统后封混凝土压浆质量控制方法，该技术步骤为：步骤一，在上下承台之间进行模板安装；步骤二，在靠近上承台四个边角的封固区域位置安装检测管道，并在管道内安装传感器，作为检查工艺可靠性的手段和质量监督手段；步骤三，浆液制备；步骤四，将步骤三中均匀搅拌后的浆液进行质量检测，浆液技术指标符合规范规定的要求后，即可通过过滤网进入储料罐；步骤五，将步骤四中经过检查过后的浆液通过压浆装置压入至封固区之中；步骤六，待浆液强度达到规定值后方进行拆模；利用振动传感器进行质量控制，后封混凝土压浆质量满足施工要求，有效保证了桥梁结构的安全性和整体性，有利于承台上部荷载合理传递到基础部分。
