施插排水板要在砂墊層完成后施工

塑(su)(su)料排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)要在砂(sha)墊層完(wan)成(cheng)后施工(gong)(gong)，由(you)測量(liang)人員測量(liang)出需處(chu)理(li)的范圍，用小(xiao)竹(zhu)簽定出每根(gen)(gen)排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)的具體-位置，插(cha)板(ban)(ban)(ban)機對中調平，把(ba)排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)在鉆(zhan)頭上安放好，開動打(da)樁機錘打(da)鉆(zhan)桿，將(jiang)塑(su)(su)料排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)送入設(she)計深-度(du)，把(ba)鉆(zhan)桿提(ti)上來，將(jiang)地(di)面(mian)上的塑(su)(su)料排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)截斷，并留有一定富余長度(du)，在塑(su)(su)料排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)四周填砂(sha)后即完(wan)成(cheng)本(ben)根(gen)(gen)排(pai)水(shui)(shui)(shui)(shui)板(ban)(ban)(ban)的施工(gong)(gong)。

施工中一定要注(zhu)意回帶現象，即雖然鉆頭(tou)打至(zhi)設計(ji)深-度，但(dan)提(ti)升鉆桿(gan)時，塑料(liao)排水板(ban)隨鉆桿(gan)提(ti)升而上升的現象，此時要采(cai)用(yong)在鉆頭(tou)用(yong)短(duan)鋼筋頭(tou)等辦(ban)法(fa)防止回帶現象。

排水(shui)板的主要是(shi)做好防水(shui)：

排水板(ban)是(shi)屋(wu)(wu)頂(ding)綠(lv)化防(fang)水板(ban)作用(yong)，設計(ji)都是(shi)按屋(wu)(wu)面(mian)結(jie)構進行多道防(fang)水設施做防(fang)排水構造的(de)系(xi)統(tong)處理，植物的(de)根系(xi)均具有很強的(de)穿刺能力(li)，防(fang)止屋(wu)(wu)面(mian)滲漏可以在屋(wu)(wu)面(mian)鋪設阻根防(fang)水料。

防水(shui)(shui)層施(shi)工后必-須對蓄水(shui)(shui)進行抽查，檢驗無滲漏(lou)后鋪設排(pai)水(shui)(shui)層，排(pai)水(shui)(shui)層用塑料排(pai)水(shui)(shui)板或蓄排(pai)水(shui)(shui)板

排水層(ceng)(ceng)放(fang)置(zhi)隔離(li)層(ceng)(ceng)因(yin)下雨澆水多余的水可(ke)以通(tong)過隔離(li)層(ceng)(ceng)過濾后排出去(qu)，以防植(zhi)物(wu)爛根將種植(zhi)層(ceng)(ceng)介質保留下來避免流失，隔離(li)層(ceng)(ceng)可(ke)用纖維土工布在隔離(li)層(ceng)(ceng)上鋪置(zhi)種植(zhi)層(ceng)(ceng)。
