New and old structure underground corridor foundation connection construction joint anti-seepage treatment method
The invention relates to the technical field of constructional engineering, and particularly discloses a new and old structure underground corridor foundation connection construction joint anti-seepage treatment method which specifically comprises the following steps that the side, close to a new foundation, of an original foundation is excavated, so that a step-shaped construction joint is formed; mounting embedded steel bars and water stop components on the vertical surface of the construction joint; the embedded steel bars extend into the new foundation; a concrete cushion layer, a leveling layer, a waterproof layer and a waterproof protection layer are sequentially constructed at the bottom of the foundation trench of the newly-built underground corridor; original foundation steel bars are connected with new foundation steel bars, and new foundation waterproof concrete is poured; after the new foundation is poured, a channel steel-shaped drainage belt is mounted above the construction joint; one side of the drainage belt is inserted into the original foundation, and the other side of the drainage belt is inserted into the new foundation. Compared with the prior art, the waterproof and anti-seepage structure has good waterproof and anti-seepage effects.
本发明涉及建筑工程技术领域，具体公开了一种新老结构地下连廊基础连接施工缝防渗漏处理的方法，具体包括以下步骤：对原基础靠新基础一侧开凿，使其形成呈台阶状的一条施工缝；在施工缝的竖向面上进行植筋和止水部件的安装；植筋伸入新基础内；在新建地下连廊的基槽底部依次施工混凝土垫层、找平层、防水层、防水保护层；原基础钢筋与新基础钢筋连接、新基础防水混凝土浇筑；新基础浇筑完成后，在施工缝的上方安装呈槽钢状的排水带；所述排水带的开口向下，其一侧插入原基础内，另外一侧插入新基础内。相比现有技术，本发明具有良好的防水抗渗漏的效果。
