Fabricated underground diaphragm wall capable of being quickly connected with prestressed tendons and construction method of fabricated underground diaphragm wall
The invention provides a fabricated underground diaphragm wall connected with prestressed tendons and a construction method of the fabricated underground diaphragm wall. The fabricated underground diaphragm wall is characterized in that wall pieces of the underground diaphragm wall are divided into bottom wall pieces and connecting wall pieces; a cavity is formed in a wall piece of the underground diaphragm wall, and after the wall piece is hoisted and prestress construction is completed, concrete is poured to fill the cavity; second prestressed tendons are preset in the preset hole channels of all the sections of connecting wall pieces, and when the wall pieces are hoisted, the second prestressed tendons are rapidly connected through the connecting fasteners. The underground diaphragm wall structure is in a prefabricated cavity form, and is light in self weight and convenient to mechanically hoist; the underground diaphragm wall adopts the structural design of combining prefabrication and cast-in-place, so that the rigidity can be increased, and the integrity of the wall body is enhanced. The underground diaphragm wall pieces are divided into the connecting wall pieces and the bottom wall pieces, the types are few, the wall pieces are good in universality, and the installation efficiency is improved. The method is environmentally friendly, installation can be completed only through a hoisting machine and a prestress applying machine, the prestressed tendon connection construction steps are greatly simplified, and the construction progress is accelerated.
本发明提供了一种装配式连接预应力筋的地下连续墙及其施工方法，本发明将地连墙墙片分为底部墙片和连接墙片两种；地连墙的墙片内部设有空腔，待墙片吊装完成且预应力施工完毕后，浇筑混凝土充满空腔；每段连接墙片的预设孔道内预置第二预应力筋，吊装墙片时通过连接扣件实现第二预应力筋的快速连接。本发明的地连墙结构为预制空腔形式，其自重轻，便于机械吊装；地连墙采用预制与现浇相结合的结构设计，可增加刚度，增强墙体的整体性。地连墙墙片分为连接墙片和底部墙片，类型少，墙片通用性好，提高安装效率。本发明的环境友好，只需吊装机械与预应力施加机械即可完成安装，预应力筋连接施工步骤大大简化，加快施工进度。
