排水板行業簡介

一、排水板的價格是多少

排水板是一種土工材料，鋪設在屋頂、車庫頂板、建筑物基礎上層或下層等場所，起到排水的作用。市面上排水板的價格一般是按面積計算的，計算時，以克重折算出每平米的價格，一般來說，16mm排水板價格大約在9元每平方左右，20mm排水板價格大約在10.5元每平方左右，30mm排水板價格大約在13.5元每平方左右。當然，每平米的重量也是要根據凸高的不同來確定重量，例如凸高2cm的排水板，推薦重量在1400g左右每一米，那么價格大約在8元左右每平米，如果做1000克左右，每平米價格在5.8元左右。另外，排水板作為塑料制品，其使用的材質、型號、選擇的生產廠家、購買數量等因素也會影響到它的價格。選購排水板時，除了價格外，還要注意選擇一個靠譜的排水板品牌，并可以通過看、壓(ya)、折、提四個(ge)方法簡單(dan)判斷(duan)排水板的質量(liang)好壞。

二、排水板和土工布怎么鋪裝

1、首先檢查(cha)基(ji)(ji)底，保證基(ji)(ji)底的(de)干燥平整，含水量少于(yu)9%。2、然(ran)后用刷(shua)子均勻地刷(shua)上瀝青溶液，等干掉后鋪裝排水板，把排水板四邊的(de)齒(chi)孔扣緊，杯(bei)狀口要向上。3、再在上面蓋土(tu)木布，以10-20公分(fen)的(de)距離重疊。4、接著撒上中粗砂、鋪上種植土(tu)。5、最后做好養護即可。

四、排水板凸點朝上還是朝下

排(pai)水(shui)板(ban)有凹面和凸面，很多朋友在安(an)裝(zhuang)(zhuang)時不知道應(ying)該(gai)把(ba)凸點(dian)那(nei)(nei)面朝上(shang)(shang)安(an)裝(zhuang)(zhuang)還是把(ba)凹面朝上(shang)(shang)安(an)裝(zhuang)(zhuang)，其實(shi)這需(xu)要(yao)根(gen)(gen)據水(shui)流的方向來定。如果(guo)是裝(zhuang)(zhuang)在地(di)面上(shang)(shang)的排(pai)水(shui)板(ban)，水(shui)從地(di)下(xia)(xia)上(shang)(shang)來的，那(nei)(nei)么凸點(dian)應(ying)該(gai)朝下(xia)(xia)，如果(guo)是安(an)裝(zhuang)(zhuang)在頂部的排(pai)水(shui)板(ban)，水(shui)是從上(shang)(shang)面下(xia)(xia)來的，那(nei)(nei)么凸點(dian)就應(ying)該(gai)朝上(shang)(shang)，總而言之(zhi)，就是凸點(dian)的方向需(xu)要(yao)作(zuo)為迎(ying)水(shui)面。用戶(hu)在安(an)裝(zhuang)(zhuang)的時候，需(xu)要(yao)根(gen)(gen)據實(shi)際需(xu)求來進行操作(zuo)，避免影響排(pai)水(shui)。
