advantage：
1, simple structure, easy to install. Modular, modular structure without the need to use large-scale construction equipment, saving manpower, material and financial resources, the construction period is small.
2, with full security. Steel Shields Fully protect rubber dam bags, dam bags can provide a full buffer force, not afraid of the sudden impact of large floating objects.
3, the ecological landscape effect is good. Dam overflow will form a waterfall, very beautiful.
4, management and operation costs low. No card hangs during operation, without frequent maintenance.
5, clean and clear capacity of siltation. When the collapse of the shield board completely attached to the foundation, water blocking height of less than 9 cm.
6, stronger earthquake resistance. Between the shield and the foundation is a soft connection, not because of the basic deformation caused by system failure and loss of normal operation.
7, for a wide range of applications. Applicable to all kinds of hydrological complex river, suitable for urban landscaping construction. But also can be directly applied to a variety of rubber dam, automatic flap dam transformation.

composition：

Mainly by the civil part, steel shield, rubber balloon, anchor, charge and exhaust facilities and control systems and other components。
