Concrete encapsulation method for large-diameter pipeline
The invention relates to the technical field of concrete encapsulation for pipelines, and especially relates to a concrete encapsulation method for a large-diameter pipeline. The concrete encapsulation method for the large-diameter pipeline comprises the following steps: a plain concrete layer is laid at the bottom of a groove, and the upper surface of the plain concrete layer is flattened; and a plurality of prefabricated bases are laid on the plain concrete layer at intervals in the length direction of a pipeline needing to be laid, arc-shaped seats are integrally arranged on the prefabricated bases, the surfaces, back to the prefabricated bases, of the arc-shaped seats are arc-shaped. The concrete encapsulation method for the large-diameter pipeline further comprises the following steps: a steel bar assembly is installed, the pipeline is hoisted, and an inner steel bar cage is arranged at the outer side of the pipeline; and the pipeline is placed on the arc-shaped seats, then formworks are erected at the two sides of the pipeline, the formworks are fixedly connected with the prefabricated bases, the formworks are connected with a plurality of pressing assemblies used for forming inclined downward symmetrical acting force on the two sides of the upper portion of the pipeline, and concrete is poured between the formworks and the pipeline to form an encapsulation layer. The concrete encapsulation method for the large-diameter pipeline has the effect of reducing movement of the pipeline in the encapsulation process.
本申请涉及一种管道混凝土包封的技术领域，尤其是涉及一种大口径管道混凝土包封方法，其包括如下步骤，在沟槽的底部铺设一层素混凝土层，所述素混凝土层的上表面进行平整；在素混凝土层上沿着需要铺设管道的长度方向间隔铺设多个预制底座，所述预制底座上一体设置有弧形座，所述弧形座背向预制底座的一面为弧形，还包括安装钢筋组件和吊装管道，以及在管道的外侧设置内钢筋笼，所述管道放置到弧形座上，然后在所述管道的两侧搭设模板，模板与预制底座固定连接，在所述模板上连接用于对管道上部两侧形成倾斜向下的对称作用力的多个压紧组件，在所述模板与管道之间浇筑混凝土形成包封层。本申请具有减少管道在包封过程中发生移动的效果。
