整體到貨的閘門在安裝前,應(yīng)對(duì)其各項(xiàng)進(jìn)行復(fù)查。分節(jié)到貨的閘門組成整體后,其各項(xiàng)尺寸,按有關(guān)規(guī)定進(jìn)行復(fù)查,應(yīng)滿足下列要求:節(jié)間如采用螺栓連接,則螺栓應(yīng)均勻擰緊,節(jié)間橡皮的壓縮量應(yīng)符合圖紙規(guī)定。

  1、 整體到貨的閘門在安裝前,應(yīng)對(duì)其各項(xiàng)進(jìn)行復(fù)查。

  2、 分節(jié)到貨的閘門組成整體后,其各項(xiàng)尺寸,按有關(guān)規(guī)定進(jìn)行復(fù)查,應(yīng)滿足下列要求:

  (1) 節(jié)間如采用螺栓連接,則螺栓應(yīng)均勻擰緊,節(jié)間橡皮的壓縮量應(yīng)符合圖紙規(guī)定。

  (2) 節(jié)間如采用焊接,則焊接前應(yīng)編制焊接工藝規(guī)程,焊接時(shí)應(yīng)監(jiān)視變形。

  3、 止水橡皮的螺孔應(yīng)按門葉或止水壓板上的螺孔位置定出,然后進(jìn)行沖孔或鉆孔,孔徑應(yīng)比螺栓直徑小1㎜,嚴(yán)禁燙孔。當(dāng)螺栓均勻擰緊后,其端頭應(yīng)低于止水橡皮自由表面8㎜以上。

平面閘門

  4、 止水橡皮表面應(yīng)光滑平直,不得盤折存放。其厚度允許偏差為±1㎜,其余外形尺寸的允許偏差為設(shè)計(jì)尺寸的2%。

  5、 止水橡皮接頭可采用生膠熱壓等方法膠合,膠合接頭處不得有錯(cuò)位、凹凸不平和疏松現(xiàn)象。

  6、 止水橡皮安裝后,兩側(cè)止水中心距離和頂止水中心至底止水底緣距離的偏差均不應(yīng)_過(guò)±3㎜,止水不平度不應(yīng)_過(guò)2㎜。閘門處于工作部位后,止水橡皮的壓縮量應(yīng)符合圖紙規(guī)定。其允許偏差為-1+2㎜。啟閉機(jī)

  7、 單吊點(diǎn)的平面閘門應(yīng)作靜平衡試驗(yàn),試驗(yàn)方法為:將閘門吊離地面100㎜,通過(guò)滾輪或滑道的中心測(cè)量上、下游與左、右方向的傾斜度不應(yīng)_過(guò)門高的1/1000,且不大于8㎜。
