Steel gate installation method

1、首先测量主、反轨道厚度的尺寸和闸门的厚度尺寸，三者尺寸之和应小于闸槽的预留尺寸，如小于的话可以准备安装，如大于的话要设法找原因解决。

1, first, measure the thickness of the main and counter tracks and the thickness of the gate. The size of the three shall be smaller than the reserved size of the gate slot. If it is less than that, it can be ready for installation.

2、看准流水方向和闸门是前止水﹙面板止水﹚还是后止水。

2, the flow direction and gate are the front water stop (panel water stop) or after water stop.

3、测量、寻找吊点中心线和闸门底止水的位置尺寸，明确闸门的底止水在闸槽的位置。

3, measure, find the center line of the hanging point and the position of the water stop at the bottom of the gate, and make clear the position of the bottom stop of the gate in the gate.

4、根据闸门底止水在闸槽中的位置，把底坎放入闸槽底部，尽量使底止水在底坎面板的中央位置，用水平尺测量底坎面的平整度，水平后开始点焊稳固。

4, according to the location of the bottom gate's water stop in the sluice, put the bottom cannulas into the bottom of the sluice, try to make the bottom water stop in the central position of the bottom panel, measure the flatness of the bottom surface with the horizontal ruler, and then start the spot welding stabilization after the level.

5、再按出水口宽度和闸门的厚度，确定主轨的位置用垂线吊直主轨面然后把主轨的钢筋和预埋筋点焊连接稳定。

5. According to the width of the outlet and the thickness of the gate, the position of the main rail is determined by the vertical line, and then the steel bar of the main rail and the spot welding of the preburied reinforcement are stable.

6、根据出水口尺寸和闸门的宽度放反轨，其方法和稳定主轨方法一样。 

6. According to the size of the outlet and the width of the gate, the method is the same as the method of stabilizing the main rail.  

7、安装门楣，按出水口的高度为门楣的底部，门楣的面和迎水面的轨道面相平，然后和预埋钢筋点焊连接。 

7, the installation height of the lintel, according to the water outlet at the bottom of the door lintel, rail surface and the surface is flat, and then pre buried steel spot welding.  

8、都点焊连接住后，再重新测量出水口的宽高和门槽的宽度，如都符合图纸要求的尺寸，就开始焊接稳固；如有不符，调整后焊接稳固。 

8, after the spot welding is connected, the width and width of the outlet will be re measured. If all sizes meet the requirements of the drawings, the welding will start to be stable. If there is any discrepancy, the welding will be stable after adjustment.  

9、焊接稳固好后，可以顺闸门试装，试装顺利吊起闸门，按二期预留的尺寸支盒子板准备进行灌注混凝土；试装不顺利找出问题，调整好再灌注混凝土。

9, after the welding is stable, the gate can be tested and installed. Trial installation will smoothly lift the gate. According to the two stage reserved size, the sub board will be ready for pouring concrete. If the test is not successful, it will find out the problem and adjust the reperfused concrete.

10、不锈钢插板闸门和调节堰门一般和闸槽是一体的，首先把闸门设计出水口对准，工地现场出水口，然后从侧面和正面将闸槽吊线调正，和一期预埋钢板或预埋钢筋连接固定，再做二期混凝土预埋。 

10, stainless steel plate gate and regulating checkgate generally and gate slot is one of the first water outlet gate design alignment, site outlet, and then from the side and front gate slot suspension alignment, and a pre buried steel or pre buried steel fixed do two buried in concrete.  

11、有栅槽的格栅拦污栅、筛网拦污栅安装方法参照以上说明。

11, the gate slot grille screen rack trash rack, installation method according to the above description.
