二次衬砌砼端头定形弧模回定止水带施工方法
摘要：
本发明公开了一种二次衬砌砼端头定形弧模回定止水带施工方法，首先在二次衬砌台车端头焊接钢板，然后在钢板端头点焊的U形钢筋箍，将中埋式橡胶止水带一端安装在U形钢筋箍内，另一端反压在钢板上，使得预埋在下一幅浇筑二次衬砌砼内的中埋式橡胶止水带与已经浇筑的二次衬砌台的砼面隔离开；采用木模板封端模；最后在二次衬砌浇筑完成砼后，拆除二次衬砌台车，使得U形钢筋箍与钢板脱离。本发明采用的二次衬砌砼端头定形弧模回定止水带施工方法，通过加工二衬端头定型弧模，可确保中埋式橡胶止水带要确保预埋在已浇筑二次衬砌砼在待浇二次衬砌砼内。定型弧模焊接在二衬台车端头模板上，投入小、加工容易，施工操作简便，可大面积推广。
摘要（英）：

The invention discloses a construction method for pre-positioning a water stop belt of a setting arc-shaped die of a quadratic lining concrete end head. The method comprises the steps of welding a steel plate at the end head of a quadratic lining concrete trolley; arranging a U-shaped steel bar loop at the end head of the steel plate by spot welding; mounting one end of an embedded rubber water stop belt into the U-shaped steel bar loop and arranging the other end on the steel plate by reverse pressing to separate the embedded rubber water stop belt embedded into the quadratic lining concrete to be poured from the concrete surface of a poured quadratic lining concrete platform; sealing an end die through a wooden die plate; dismounting the quadratic lining concrete trolley after pouring the quadrate lining concrete so as to separate the U-shaped steel bar loop from the steel plate. According to the construction method for pre-positioning the water stop belt of the setting arc-shaped die of the quadratic lining concrete end head, the setting arc-shaped die of the quadratic lining concrete end head is processed, so that the embedded rubber water stop belt can be embedded into the quadrate lining concrete to be poured of the poured quadratic lining concrete; the setting arc-shaped die is welded on the end head die plate of the quadratic lining trolley; the investment is small, the processing is easy, the construction is simple and convenient, and wide popularization can be carried out.
