氯丁橡(xiang)胶棒 面(mian)板坝常(chang)规止(zhi)(zhi)水(shui)结构型式通常(chang)采用三道止(zhi)(zhi)水(shui),即在(zai)表层接(jie)缝(feng)设(she)置有(you)盖板保护的塑(su)性嵌缝(feng)填料,在(zai)接(jie)缝(feng)中部设(she)置止(zhi)(zhi)水(shui)带,在(zai)接(jie)缝(feng)底(di)部设(she)置铜止(zhi)(zhi)水(shui)。
工程(cheng)实践表明,该(gai)止水型(xing)式中(zhong)(zhong)(zhong)的中(zhong)(zhong)(zhong)部止水带(dai)在(zai)施工中(zhong)(zhong)(zhong)很难与混(hun)凝土紧密结(jie)合,常发生漏水;同时在(zai)接缝(feng)位移作用下,接缝(feng)中(zhong)(zhong)(zhong)的止水带(dai)产生的集中(zhong)(zhong)(zhong)应变(bian)较大,一旦被(bei)破坏,将降(jiang)低止水结(jie)构的效用.即流动(dong)止水型(xing)式在(zai)结(jie)构上(shang)是有缺(que)陷的。
鉴于常规中(zhong)(zhong)部(bu)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带很难正常发挥(hui)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)作(zuo)用(yong),中(zhong)(zhong)国水(shui)(shui)(shui)科院在(zai)九五(wu)期间(jian)提出了一个新的止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)结构(gou)型(xing)式(shi),该(gai)型(xing)式(shi)将中(zhong)(zhong)部(bu)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带提至表层(ceng),采用(yong)在(zai)趾板和面(mian)板中(zhong)(zhong)预埋的角钢(gang)和固定(ding)(ding)螺栓(shuan)将止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带固定(ding)(ding)在(zai)缝口(kou)位置。为(wei)了适应(ying)大接(jie)缝位移,将表层(ceng)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带设计成(cheng)变(bian)形(xing)能(neng)力(li)(li)很大的波(bo)浪形(xing);同时为(wei)了确保止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带在(zai)大接(jie)缝张开情况(kuang)下(xia)承受高水(shui)(shui)(shui)压力(li)(li)作(zuo)用(yong),在(zai)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)带下(xia)面(mian)的缝口(kou)处设置了支撑氯丁橡胶棒,氯丁橡胶棒应(ying)确保在(zai)止(zhi)(zhi)(zhi)(zhi)水(shui)(shui)(shui)运行过程中(zhong)(zhong)能(neng)够滞留在(zai)缝口(kou),不被压入接(jie)缝以发挥(hui)支撑作(zuo)用(yong)。
