In the construction of deep shaft lining concrete structures such as mountain and water conservancy projects, the bracket method is generally used for construction.
现有技术中的支架法是在竖井中按一定间隔的搭设脚手架作为模具的内支撑、利用小块钢模板拼接形成内模进行竖井衬砌施工的方法，支架法衬砌对场地的要求极高，适用于深度不大的竖井，虽然投入较小，但是采用支架法进行衬砌施工存在搭设脚手架需要的劳动强度很大、需要先搭设脚手架再进行衬砌施工、脱模过程也较为麻烦，整个过程消耗的时间长且工序复杂、功效较低以及操作人员安全等缺陷。The scaffolding method in the prior art is to set up scaffolds in the shaft at certain intervals as the internal support of the mold, and use small steel templates to splice to form an internal mold for shaft lining construction. The scaffolding method lining has extremely high requirements on the site and is applicable For shafts with small depths, although the investment is small, the use of the scaffolding method for lining construction requires a lot of labor intensity. The scaffolding needs to be erected before the lining construction. The demoulding process is also troublesome, and the entire process consumes time. Defects such as long and complicated procedures, low efficiency and operator safety.
专利CN203905948U公开了一种圆形竖井内衬用自承一体模板体系，圆形衬砌直口钢、圆形衬砌直斜口钢模板和圆形衬砌斜口钢模板构成外部框架，模板直对直口或斜对斜口通过高强螺栓连接，模板无需搭设脚手架、横撑等支撑体系，自承一体，该体系解决了逆作法圆形竖井内衬施工中支撑体系繁琐、拆装复杂、放料及捣鼓困难、不安全等问题。但由于该体系中模板数量众多，在模板的组装过程中，需要连接较多的模板，操作十分麻烦。Patent CN203905948U discloses a self-supporting integrated formwork system for lining circular shafts. The circular lining straight steel form, the circular lining straight inclined steel formwork and the circular lining inclined steel formwork form an external frame, and the formwork is straight to the straight mouth. Or the diagonally opposite inclined openings are connected by high-strength bolts. The formwork does not need to be built with scaffolding, transverse bracing and other supporting systems, and is self-supporting. This system solves the cumbersome support system, complicated disassembly and assembly, and difficulty in discharging and tamping in the construction of the circular shaft lining with the reverse construction method. , Insecurity and other issues. However, due to the large number of templates in this system, in the assembly process of the templates, more templates need to be connected, which is very troublesome to operate.

相邻两个模板组通过连接件可拆卸地连接，连接件用于在浇筑时固定第一模板和第二模板，Two adjacent formwork groups are detachably connected by connecting pieces, which are used to fix the first formwork and the second formwork during pouring,
竖井衬砌施工方法包括以下步骤：The construction method of shaft lining includes the following steps:
浇筑步骤：将吊盘模板装置置于竖井中，向吊盘模板装置外侧浇筑混凝土；Pouring steps: Place the hanging plate formwork device in the shaft, and pour concrete to the outside of the hanging plate formwork device;
脱模步骤：当浇筑的竖井衬砌混凝土达到拆模强度后，取下连接件，将第一模板绕第一模板与第二模板的连接处向柱状结构的中空部分转动使第一模板脱模，然后向柱状结构的中空部分的中心处移动第二模板使模板组与已浇筑的竖井井壁分离。Demoulding step: when the poured shaft lining concrete reaches the demoulding strength, remove the connecting piece, and rotate the first formwork around the connection between the first formwork and the second formwork to the hollow part of the columnar structure to demould the first formwork. Then move the second template to the center of the hollow part of the columnar structure to separate the template group from the casted shaft wall.
通过上述方案，吊盘模板装置上设有至少两组模板组和连接件，至少两组模板组拼接形成周向封闭的中空柱状结构，从而形成用于竖井成型的内模，模板组包括第一模板和第二模板，第一模板与第二模板可转动地连接，第二模板能够沿柱状结构的径向方向运动是为了确保模板组能够顺利脱模，当浇筑完成且达到拆模强度后，操作人员只需先取下连接件，绕第一模板与第二模板的连接处向柱状结构的中空部分转动第一模板使第一模板脱离，再向柱状结构的中空部分的中心处移动第二模板即可使模板组与已浇筑成型的竖井井壁分离。该装置操作简单，可以通过转动第一模板和第二模板，使第一模板和第二模板拼接形成更大的模板组，从而可以减少模板组装过程中的工作量，不需要大量的人力物力就可以完成竖井衬砌施工，施工速度快，提高了工作效率和施工进度。Through the above solution, the hanging plate formwork device is provided with at least two sets of formwork groups and connectors, and at least two sets of formwork groups are spliced to form a circumferentially closed hollow columnar structure, thereby forming an inner mold for shaft forming.
