整体到货的闸门在安装前,应对其各项进行复查。分节到货的闸门组成整体后,其各项尺寸,按有关规定进行复查,应满足下列要求:节间如采用螺栓连接,则螺栓应均匀拧紧,节间橡皮的压缩量应符合图纸规定。

  1、 整体到货的闸门在安装前,应对其各项进行复查。

  2、 分节到货的闸门组成整体后,其各项尺寸,按有关规定进行复查,应满足下列要求:

  (1) 节间如采用螺栓连接,则螺栓应均匀拧紧,节间橡皮的压缩量应符合图纸规定。

  (2) 节间如采用焊接,则焊接前应编制焊接工艺规程,焊接时应监视变形。

  3、 止水橡皮的螺孔应按门叶或止水压板上的螺孔位置定出,然后进行冲孔或钻孔,孔径应比螺栓直径小1㎜,严禁烫孔。当螺栓均匀拧紧后,其端头应低于止水橡皮自由表面8㎜以上。

  4、 止水橡皮表面应光滑平直,不得盘折存放。其厚度允许偏差为±1㎜,其余外形尺寸的允许偏差为设计尺寸的2%。

  5、 止水橡皮接头可采用生胶热压等方法胶合,胶合接头处不得有错位、凹凸不平和疏松现象。

  6、 止水橡皮安装后,两侧止水中心距离和顶止水中心至底止水底缘距离的偏差均不应_过±3㎜,止水不平度不应_过2㎜。闸门处于工作部位后,止水橡皮的压缩量应符合图纸规定。其允许偏差为-1+2㎜。启闭机

  7、 单吊点的平面闸门应作静平衡试验,试验方法为:将闸门吊离地面100㎜,通过滚轮或滑道的中心测量上、下游与左、右方向的倾斜度不应_过门高的1/1000,且不大于8㎜。
