钢坝液压坝特点：

1.結果简易，沒有繁杂的传动系统预制构件，水闸一部分基础沒有必须维护保养、维修的位置，水闸运作的可靠性和可信性获得极大地提升，河堤中的脏物不易被卡，即便卡也是容下的室内空间，并且很容易清除；
2.钢架结构液压坝挡水一部分为一个总体，沒有拼凑缝。而钢筋混凝土水闸是根据多快混凝土构件拼凑而成，因而拼凑间隙非常容易产生渗水；
3、水闸不容易产生纵向挪动，处理了纵向渗水难题，当侧停水硫化橡胶被脏物毁坏时，能够在储水情况开展拆换，不容易危害一切正常的发电量；
4、水闸被物块单侧卡时不容易产生一端高一端低的歪曲形变，因而不容易导致水闸中间互相影响；

5、因为钢架结构液压坝门页刚度好，抗压强度高，不容易象混凝土结构那般易裂，就算被超重量级物块撞击，也总是产生部分形变，修补简易，不用运送安全通道花费低，修复更快；
钢架结构翻板闸门不容易产生被水灾浮上来冲跑的比较严重难题,不容易造成敲打状况
6、钢架结构液压坝因为选用绞链方法联接，不容易产生被水灾浮上来冲跑的比较严重难题，拥有液压传动系统的功效更为不容易造成敲打状况；
7、由于总体设计的合理化，水闸受压遍布平衡，能够考虑大跨距、较高水闸的规定。在同样跨距和高宽比的状况下，能够很多节约钢才使用量，不用水闸上方的门槽构造和价格比较贵的开闭机器设备；
8、由于全部的预制构件都会水坝之外生产制造， 环节才进到当场安裝工作中，液压传动系统的安裝能够在储水情况下开展，因而能够大大缩短了工程施工施工期，另外减少了水坝的复杂度和工程施工难度系数液压机液压坝依据安裝当场的状况，有时候液压坝必须配置专用型橡胶支座。

.3.3.5 hydraulic cylinder
The hydraulic cylinder is connected with the foundation embedded plate in the first-stage concrete through the support hinge. The piston rod lifting head is connected with the bottom shaft of the flap gate by the lifting shaft through the crank arm.
The hydraulic cylinder body, piston and piston rod must be delivered in a complete set. The ceramic piston rod can be subcontracted for processing by the contractor. However, the subcontractor shall obtain the approval and written approval of the employer, supervisor and engineering design unit in advance.
The assembled cylinder assembly shall have hooks or devices for installation and transportation.
The design of the hydraulic cylinder must meet or exceed the service characteristics specified in this technical specification or SL41 (water
The provisions of the design specification of electric hydraulic engineering hoist and shutter. The hydraulic cylinder is designed with single piston rod type, double action and heavy load. The hydraulic cylinder is provided with a lifting head (with self-lubricating joint bearing) and a connecting pin shaft at the overhanging end of the piston rod, and its size and type match with the lifting lug of the gate. The manufacture of hydraulic cylinders must comply with DL/T5019 (code for construction, installation and acceptance of opening and closing mechanisms for water conservancy and hydropower projects).
1, the hydraulic cylinder cylinder body should be priority to use the whole section of seamless steel pipe production, material should meet or equivalent
The mechanical properties of no. 45 steel of GB/T699 or 0345B of GB/T1521 shall meet the requirements of the specification after hot treatment specified in GB/T699 or GB/T1591. When sectional welding is adopted, the welding parts of the cylinder body shall be treated by tempering and tempering, and the welding dimension shall be qualified by ultrasonic inspection and appearance inspection of 100% weld length according to the requirements of the first level welding seam, and conform to JB1151 (ultrasonic inspection regulations on high-pressure seamless steel tube). Where welding is used, weld inspection data should be provided, according to the ANSIB46.1 hydraulic cylinder inner diameter surface processing recommended to use question I, the coarse flame must reach more than 0.4ym
