面板坝常规止水结构型式通常采用三道止水，即在表层接缝设置有盖板保护的塑性嵌缝填料，在接缝中部设置止水带，在接缝底部设置铜止水。工程实践表明，该止水型式中的中部止水带在施工中很难与混凝土紧密结合，常发生漏水；同时在接缝位移作用下，接缝中的止水带产生的集中应变较大，一旦被破坏，将降低止水结构的效用，即流动止水型式在结构上是有缺陷的。
Dam type conventional sealing structure usually adopts three water stopping, namely in the setting of joint surface plastic sealing filler cover protection, sealing belt is arranged in a joint central copper seal in the bottom seam settings. The engineering practice shows that the central water watertight type bands in the construction is difficult to combine with concrete, often occurs at the same time in Water Leakage; joint displacement under the action of water in the seam with large strain, once destroyed, will reduce the utility of the sealing structure, which is current in the structure is a watertight type defect.

鉴于常规中部止水带很难正常发挥止水作用，中国水科院在九五期间提出了一个新的止水结构型式，该型式将中部止水带提至表层，采用在趾板和面板中预埋的角钢和固定螺栓将止水带固定在缝口位置，为了适应大接缝位移，将表层止水带设计成变动能力很大的波浪形；同时为了确保止水带在大接缝张开情况下随高水压力作用，在止水带下面的缝口处设置了支撑氯丁橡胶棒，氯丁橡胶棒应确保在止水动行过程中能够留在缝口，不被压入接缝口处设置了支撑氯丁橡胶棒，氯丁橡胶棒应确保在止水动动过程中能够滞留在缝口，不被压入接缝以发挥支撑作用。
In view of the conventional central waterstop is difficult to play the sealing effect, China academy proposed a new type of sealing structure in the 95 period, the type of the middle sealing strip to the surface, the water seal belt is fixed in the seam position by embedded in the toe board and panel in angle and fixed bolts, in order to adapt to the large joint the surface displacement, the waterstop design changes in a great capacity to wave to; in order to ensure the sealing strip in the joint open case with high water pressure, the waterstop seam is arranged below the supporting rod of chloroprene rubber, chloroprene rubber rod should be ensured in the process of moving water to stay seam No, is pressed into the joint is arranged at the opening of the supporting rod of chloroprene rubber, chloroprene rubber rod should ensure retention in the seam in the water can move in the process of export, not be pressed into the joint to play a supporting role.

氯丁橡胶棒是以氯丁橡胶为主加与各种合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼、混炼、挤出成型，高温硫化，它具有耐老化、耐油、耐磨性、适用于在面板坝的理想材料。
Chloroprene rubber stick is neoprene and all kinds of synthetic rubber as the main raw material, and the filling material mixed with various additives, through plasticizing, mixing, extrusion molding, high temperature curing, it is resistant to aging, oil resistance, wear resistance, suitable for ideal materials in dam.
