雜亂環境下的鍍鋅石籠網怎么施工
鍍鋅石籠網為半剛性(xing)(xing)水(shui)利(li)(li)柔性(xing)(xing)防(fang)護產品,具有(you)極(ji)強的(de)防(fang)護性(xing)(xing)和生態(tai)美化效(xiao)果能逆轉水(shui)利(li)(li)生態(tai)、防(fang)護兩難結合的(de)局面,產品是由高上鋅金屬線材(cai)采用六角擰編工(gong)藝、一次性(xing)(xing)成(cheng)型加工(gong)工(gong)藝而成(cheng),配(pei)以塊石修建(jian)的(de)石籠網擋墻具有(you)極(ji)強的(de)穩固性(xing)(xing)和防(fang)沖(chong)刷功(gong)能廣泛(fan)用于渠(qu)道、河床(chuang)及邊坡防(fang)護等項目的(de)建(jian)設。
鍍(du)鋅(xin)石籠網(wang)在雜(za)亂的(de)環(huan)境(jing)下的(de)應(ying)(ying)用,眾所周知,鍍(du)鋅(xin)石籠網(wang)的(de)適(shi)應(ying)(ying)能力很強,在惡劣的(de)環(huan)境(jing)條件下也能很好(hao)的(de)發揮其效果(guo)。那么鍍(du)鋅(xin)石籠網(wang)在雜(za)亂環(huan)境(jing)下是怎樣起效果(guo)的(de)呢?
彎道凹(ao)岸處的鍍(du)鋅(xin)石(shi)(shi)籠(long)網,應(ying)該按照上順下挑、上疏下密的原則設置。第一(yi)個鍍(du)鋅(xin)石(shi)(shi)籠(long)網的方(fang)位和長度(du)要穩(wen)重選(xuan)擇。一(yi)般(ban)情況(kuang)下第一(yi)鍍(du)鋅(xin)石(shi)(shi)籠(long)網應(ying)該安(an)(an)置在(zai)水流轉折點的上游(you),使(shi)水流在(zai)沒有靠近河岸之(zhi)前,就(jiu)能(neng)控(kong)制住干流,起到(dao)因勢利導的效(xiao)果。如果把(ba)第一(yi)座(zuo)鍍(du)鋅(xin)石(shi)(shi)籠(long)網安(an)(an)置在(zai)項沖點或頂沖點以下,鍍(du)鋅(xin)石(shi)(shi)籠(long)網就(jiu)不能(neng)發(fa)揮很好的效(xiao)果。
箱(xiang)內塊石間存有的縫隙和網面獨有的生(sheng)態(tai)(tai)鍍鋅(xin)石籠(long)網狀構成產(chan)品獨有的透(tou)水(shui)性和可(ke)植被性,既能(neng)利于自(zi)然界水(shui)的循環(huan)又能(neng)優化水(shui)利生(sheng)態(tai)(tai)環(huan)境、復原(yuan)自(zi)然生(sheng)態(tai)(tai)鏈.
第一(yi)步:克(ke)(ke)己平板浮船(chuan),選(xuan)用(yong)資料為關閉(bi)好的(de)空(kong)油(you)桶(tong),其平衡(heng)安穩(wen)條件極佳,每4(6)個(ge)油(you)桶(tong)聯合為一(yi)組(zu),其聯合用(yong)鐵絲網包好扎牢共(gong)做四(si)組(zu),每兩(liang)(liang)(liang)組(zu)上(shang)綁一(yi)橫(heng)(heng)梁(liang),兩(liang)(liang)(liang)組(zu)油(you)桶(tong)在橫(heng)(heng)梁(liang)兩(liang)(liang)(liang)頭,在橫(heng)(heng)梁(liang)上(shang)鋪好木板,木板厚度滿意承載要求,橫(heng)(heng)梁(liang)長度依據需要而定,木板要鋪平,這樣一(yi)個(ge)克(ke)(ke)己的(de)平板浮船(chuan)就制好了。
第二(er)步:石籠水上軟(ruan)體沉排,在(zai)規劃(hua)方位鋪設土工布。
依(yi)據水(shui)(shui)下(xia)鍍(du)鋅石籠(long)網(wang)長(chang)(chang)度確定土(tu)(tu)工布(bu)(bu)長(chang)(chang),水(shui)(shui)里(li)復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)與岸上(shang)(shang)(shang)(shang)的(de)土(tu)(tu)工布(bu)(bu)接(jie)好(hao)(hao),在復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)面上(shang)(shang)(shang)(shang)開幾個5×5cm以利(li)于排氣排水(shui)(shui),在浮(fu)船(chuan)上(shang)(shang)(shang)(shang)把水(shui)(shui)里(li)復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)最(zui)結尾的(de)兩個角上(shang)(shang)(shang)(shang)系好(hao)(hao)浮(fu)漂,此浮(fu)漂作為水(shui)(shui)里(li)鍍(du)鋅石籠(long)網(wang)結尾標志,水(shui)(shui)里(li)復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)最(zui)結尾邊(bian)上(shang)(shang)(shang)(shang)系上(shang)(shang)(shang)(shang)3至(zhi)4塊石頭(tou),使用(yong)浮(fu)船(chuan)將(jiang)(jiang)復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)在水(shui)(shui)面上(shang)(shang)(shang)(shang)抻(chen)平后將(jiang)(jiang)系在結尾石頭(tou)豎直投(tou)到(dao)水(shui)(shui)中,用(yong)這樣辦(ban)法將(jiang)(jiang)水(shui)(shui)里(li)復(fu)(fu)(fu)合(he)(he)土(tu)(tu)工布(bu)(bu)分段鋪好(hao)(hao)。
第三步:用Φ12m鋼筋(jin)做好符號(hao),在將要沉排的鍍鋅石(shi)籠網(wang)邊際處插(cha)上兩根鋼筋(jin)。
在平板浮船上裝封石(shi)(shi)(shi)籠(long)(long)(long),裝石(shi)(shi)(shi)籠(long)(long)(long)前在石(shi)(shi)(shi)籠(long)(long)(long)下每2米放(fang)一拋(pao)投石(shi)(shi)(shi)籠(long)(long)(long)的滑(hua)(hua)板,鍍鋅(xin)石(shi)(shi)(shi)籠(long)(long)(long)網用石(shi)(shi)(shi)用手(shou)推(tui)車(che)經(jing)過跳板運至船上,把石(shi)(shi)(shi)籠(long)(long)(long)裝滿封好,將(jiang)浮船劃到符(fu)號(hao)處,多人(ren)一起掀動滑(hua)(hua)板將(jiang)其(qi)拋(pao)到符(fu)號(hao)處,到岸邊將(jiang)首端與陸地石(shi)(shi)(shi)籠(long)(long)(long)相接(jie)牢固(gu)。
最后(hou):拋(pao)完一個鍍(du)鋅石(shi)(shi)籠(long)網(wang)(wang)后(hou)將(jiang)符號鋼(gang)筋(jin)拔出,插到下一個要拋(pao)的石(shi)(shi)籠(long)與(yu)已拋(pao)完的石(shi)(shi)籠(long)相鄰(lin)的邊際處,完成鍍(du)鋅石(shi)(shi)籠(long)網(wang)(wang)的鋪設工(gong)作。
