The municipal water supply and drainage pipeline construction method comprises the following steps that a groove is excavated, and a cushion block is installed, specifically, the cushion block is hoisted into the groove, the bottom of the cushion block and the bottom of the groove are tightly attached together, and the cushion block is located in the middle of the groove in the width direction; the pipeline construction equipment comprises a rack, a supporting mechanism and an upper support and is a rectangular frame, the supporting mechanism is installed on the rack, the upper support is fixedly installed on the rack, the supporting mechanism is located on the inner side of the upper support, a top base is fixedly installed in the center of the top of the upper support, and a lifting hook is installed on the top base. A lifting hook of a crane is connected with a top seat, the equipment and a pipeline placed in the equipment are lifted to the upper end of an underground tunnel together, the pipeline is placed in four supports, the supports can support the pipeline, the supports are in contact with different positions of the pipeline, acting force between the supports and the pipeline can be shared, and the pipeline can be conveniently conveyed to the upper end of the underground tunnel. Therefore, a certain fixed position of the pipeline is prevented from being damaged and deformed due to excessive pressure.
本发明涉及一种市政给排水管道施工方法,包括以下步骤:开挖沟槽和垫块安装:将垫块吊装到沟槽当中,垫块的底部与沟槽的底部紧密贴合在一起,垫块位于沟槽宽度方向的中间位置;管道施工设备包括机架、支撑机构和上支架,为矩形框架,支撑机构安装在机架上,上支架固定安装在机架上,支撑机构位于上支架内侧,上支架顶部中央处固定安装有顶座,顶座上安装有吊钩。通过吊机吊钩与顶座相连,将设备与其内放置的管道一同吊运至坑道上端,管道放置在四个支座内,支座可对管道进行支撑,通过支座对管道的不同位置处于接触状态,可分摊支座与管道之间的作用力,从而避免管道某一固定位置受压过大而发生损伤和变形。
