Novel sump open caisson bottom sealing construction method
A novel sump open caisson bottom sealing construction method comprises the following steps that firstly, a pile foundation engineering virtual pile head chiseling site is leveled; step 2, open caisson design; designing a two-dimensional plane positioning size; performing three-dimensional checking; actual construction; positioning and paying off; a sump open caisson is excavated; the site is leveled for open caisson manufacturing; removing the mold and maintaining; excavating and sinking; draining and pouring bottom sealing concrete; constructing a leveling layer; and performing waterproof construction. The prefabricated open caisson is made of reinforced concrete on site, the section size is easy to control, and concrete raw materials, pouring and curing processes can be effectively controlled. The prefabricated open caisson is divided into a blade angle part and a well wall part, the blade angle is used for facilitating sinking, and a groove is formed in the inner side of the blade angle, so that the effective water plugging effect can be achieved. The well wall of the open caisson also serves as a foundation bed, and only bottom leveling bottom layer construction needs to be conducted after the open caisson sinks to the set elevation.
一种新型集水坑沉井封底施工方法，包括有以下步骤：步骤一、桩基础工程虚桩头凿除场地平整；步骤二、沉井设计；二维平面定位尺寸设计；三维校核；实际施工；定位放线；集水坑沉井开挖；平整场地进行沉井制作；拆模养护；开挖下沉；排水浇筑封底混凝土；找平层施工；防水施工。本发明预制沉井为钢筋混凝土现场制作，截面尺寸容易控制，混凝土原材料、浇筑、养护过程可以有效控制。预制沉井分为刃角和井壁部分，刃角是为了更有利的便于下沉，刃角内侧设置凹槽能达到有效堵水的效果。沉井井壁兼做基础垫层，下沉到拟定标高后只需进行底部找平底层施工。
