塑料排水板施工(gong)(gong)是緊接著(zhu)碎石墊(dian)層施工(gong)(gong)后進(jin)行的重要(yao)分項工(gong)(gong)程(cheng)，各施工(gong)(gong)區域的施工(gong)(gong)順(shun)序(xu)和(he)碎石墊(dian)層施工(gong)(gong)順(shun)序(xu)相對應。所有區段的排水(shui)板均(jun)呈梅花形布(bu)點，排水(shui)板間(jian)距均(jun)為1.2m，要(yao)求排水(shui)板穿透淤(yu)泥層，進(jin)入下臥(wo)硬土層。

　　本工程排(pai)水板施工有(you)其特殊性：

　　1、要是排水板施工(gong)(gong)(gong)區域為潮汐帶，這(zhe)就要求施工(gong)(gong)(gong)機(ji)(ji)具必須(xu)適(shi)應漲(zhang)潮和退潮時(shi)的(de)不同狀態的(de)施工(gong)(gong)(gong)。且大(da)潮位時(shi)設(she)備有時(shi)將無法施工(gong)(gong)(gong)，所以施工(gong)(gong)(gong)現場必須(xu)準確安排好(hao)(hao)(hao)施工(gong)(gong)(gong)順(shun)序，調整好(hao)(hao)(hao)機(ji)(ji)械設(she)備，組織好(hao)(hao)(hao)施工(gong)(gong)(gong)人員，以確保工(gong)(gong)(gong)期的(de)按時(shi)完成。

　　2、主要是因為上部回填碎石，當局部振動插板困難時，可適當調整插板位置，如仍難以施打，則再反方向選取一位置，確保排水板順利打入。
