石籠網擋土墻的作用和用處

　　石籠網擋墻是將(jiang)符(fu)合要(yao)求的石(shi)(shi)料(liao)填入石(shi)(shi)籠(long)網箱中達到必定的孔隙率、逐(zhu)層砌筑的一種新式(shi)的柔性(xing)(xing)(xing)擋(dang)(dang)土墻(qiang)。柔性(xing)(xing)(xing)石(shi)(shi)籠(long)網擋(dang)(dang)墻(qiang)也能(neng)夠(gou)待石(shi)(shi)籠(long)網擋(dang)(dang)墻(qiang)沉(chen)降(jiang)必定時間后(hou)灌注稀砂(sha)漿(小礫石(shi)(shi)砂(sha)漿)，柔性(xing)(xing)(xing)石(shi)(shi)籠(long)防(fang)護沉(chen)降(jiang)安穩后(hou)覆(fu)蓋(gai)砂(sha)礫石(shi)(shi)貧混凝(ning)土，這樣(yang)能(neng)夠(gou)保證柔性(xing)(xing)(xing)石(shi)(shi)籠(long)網擋(dang)(dang)墻(qiang)耐久(jiu)性(xing)(xing)(xing)和(he)整體安穩性(xing)(xing)(xing)，能(neng)夠(gou)下降(jiang)或削減護坡(po)透水(shui)性(xing)(xing)(xing)能(neng)。本文就具(ju)體介紹關于石(shi)(shi)籠(long)網擋(dang)(dang)墻(qiang)的幾種運(yun)用。

　　石籠網擋(dang)墻的三種用處

　　1、防沖刷(shua)石籠網擋(dang)墻

　　柔(rou)性石籠(long)能(neng)夠加強(qiang)水(shui)(shui)(shui)工結構物(wu)抗(kang)水(shui)(shui)(shui)流(liu)沖(chong)刷(shua)(shua)能(neng)力，例如，有沖(chong)刷(shua)(shua)河段的擋土墻(qiang)(qiang)墻(qiang)(qiang)腳(jiao)設(she)置柔(rou)性石籠(long)護腳(jiao)，有沖(chong)刷(shua)(shua)墩臺、八字墻(qiang)(qiang)、截(jie)水(shui)(shui)(shui)墻(qiang)(qiang)以及各種受水(shui)(shui)(shui)流(liu)沖(chong)刷(shua)(shua)的水(shui)(shui)(shui)工結構物(wu)等(deng)增設(she)柔(rou)性石籠(long)護腳(jiao)(能(neng)夠沖(chong)刷(shua)(shua)后補設(she))，能(neng)夠有用下降和防止沖(chong)刷(shua)(shua)。

　　2、半剛性石籠網擋(dang)墻

　　柔(rou)性(xing)石(shi)(shi)(shi)籠(long)擋墻(qiang)(qiang)(qiang)也可根據需求(qiu)設計(ji)為柔(rou)性(xing)石(shi)(shi)(shi)籠(long)基礎(chu)(chu)半(ban)剛性(xing)石(shi)(shi)(shi)籠(long)網(wang)擋墻(qiang)(qiang)(qiang)結(jie)構，即水下(xia)部分為柔(rou)性(xing)石(shi)(shi)(shi)籠(long)基礎(chu)(chu)，水上部分每層柔(rou)性(xing)石(shi)(shi)(shi)籠(long)網(wang)擋墻(qiang)(qiang)(qiang)墻(qiang)(qiang)(qiang)心部分增加(jia)砂(sha)漿或小(xiao)礫石(shi)(shi)(shi)砂(sha)漿，石(shi)(shi)(shi)籠(long)網(wang)擋墻(qiang)(qiang)(qiang)頂砂(sha)漿壓蓋(gai)。2008 年桓蓋(gai)線平(ping)安路段運用(yong)了半(ban)剛性(xing)石(shi)(shi)(shi)籠(long)網(wang)擋墻(qiang)(qiang)(qiang)，該墻(qiang)(qiang)(qiang)既有(you)柔(rou)性(xing)石(shi)(shi)(shi)籠(long)基礎(chu)(chu)不排水施工(gong)的長處(chu)，又有(you)柔(rou)性(xing)石(shi)(shi)(shi)籠(long)網(wang)擋墻(qiang)(qiang)(qiang)整體性(xing)強的長處(chu)，一起也具有(you)漿壘墻(qiang)(qiang)(qiang)剛性(xing)特色，運用(yong)作用(yong)非常好。

　　3、滲水、透水石籠網擋墻

　　山區公路(lu)(lu)(lu)有時(shi)受汛期水(shui)(shui)土(tu)流(liu)(liu)(liu)失和(he)泥石(shi)(shi)流(liu)(liu)(liu)的作用，常出現(xian)(xian)涵洞堵(du)塞，泥水(shui)(shui)過(guo)路(lu)(lu)(lu)現(xian)(xian)象，我們要分析原因(yin)在恰當(dang)位置(zhi)選擇大粒徑石(shi)(shi)透水(shui)(shui)石(shi)(shi)籠網擋(dang)墻(qiang)攔(lan)截(jie)泥石(shi)(shi)流(liu)(liu)(liu)和(he)流(liu)(liu)(liu)失砂土(tu)，在易滑坡(po)(po)、易水(shui)(shui)土(tu)流(liu)(liu)(liu)失地段設(she)置(zhi)滲水(shui)(shui)石(shi)(shi)籠墻(qiang)，以削減和(he)掃除泥水(shui)(shui)過(guo)路(lu)(lu)(lu)病害(hai)。冬天山區公路(lu)(lu)(lu)個別路(lu)(lu)(lu)塹邊坡(po)(po)有時(shi)延(yan)流(liu)(liu)(liu)冰(bing)現(xian)(xian)象，能(neng)夠在延(yan)流(liu)(liu)(liu)冰(bing)處開挖必定空間，運用透水(shui)(shui)石(shi)(shi)籠網擋(dang)墻(qiang)圍擋(dang)攔(lan)截(jie)延(yan)流(liu)(liu)(liu)冰(bing)，并在延(yan)流(liu)(liu)(liu)冰(bing)段設(she)置(zhi)深大邊溝，緩解對(dui)公路(lu)(lu)(lu)的侵害(hai)。

　　柔性石籠(long)(long)網擋墻基礎具有適(shi)應(ying)沉降變形(xing)的特(te)色，變形(xing)后仍(reng)具有整體性，能夠帶水作業，施工(gong)(gong)簡單方便，節約工(gong)(gong)程(cheng)造價(jia)。跟著石籠(long)(long)在工(gong)(gong)程(cheng)中不斷運用(yong)和探究，特(te)別是石籠(long)(long)網(箱)專業化、工(gong)(gong)廠化批量(liang)定(ding)型加工(gong)(gong)生產，一起石籠(long)(long)網材質(zhi)的多樣化，加之(zhi)施工(gong)(gong)機械設(she)備(bei)配合(he)，使得適(shi)合(he)多用(yong)處運用(yong)的石籠(long)(long)，不僅(jin)在公路、鐵(tie)路、水利工(gong)(gong)程(cheng)中有很多的運用(yong)，也(ye)能夠在環保(bao)、綠化等其他(ta)工(gong)(gong)程(cheng)建設(she)中得到(dao)廣(guang)泛運用(yong)。
