混(hun)(hun)凝(ning)(ning)土(tu)噴漿機是噴錨支護作業(ye)的主要(yao)設備，它利用(yong)壓縮(suo)空氣將(jiang)按(an)一定(ding)級(ji)配和水灰比拌制的混(hun)(hun)凝(ning)(ning)土(tu)通過噴漿機噴嘴高速(su)噴射(she)，從而在噴射(she)面上(shang)形成混(hun)(hun)凝(ning)(ning)土(tu)支撐層。混(hun)(hun)凝(ning)(ning)土(tu)噴射(she)混(hun)(hun)凝(ning)(ning)土(tu)機廣泛應用(yong)于與建(jian)筑(zhu)、市政、鐵路公路隧(sui)道、基坑、礦(kuang)山、邊坡等相關的噴射(she)混(hun)(hun)凝(ning)(ning)土(tu)支護工程(cheng)。

混(hun)凝土(tu)噴(pen)(pen)(pen)漿(jiang)(jiang)機(ji)(ji)分(fen)為(wei)干(gan)式噴(pen)(pen)(pen)漿(jiang)(jiang)機(ji)(ji)和混(hun)凝土(tu)濕式噴(pen)(pen)(pen)漿(jiang)(jiang)機(ji)(ji)。干(gan)噴(pen)(pen)(pen)機(ji)(ji)采用(yong)干(gan)噴(pen)(pen)(pen)技術。噴(pen)(pen)(pen)射混(hun)凝土(tu)時粉塵(chen)污染(ran)和回(hui)彈嚴重，空氣質(zhi)量(liang)差，用(yong)水量(liang)控(kong)制不準確，混(hun)凝土(tu)強度難(nan)以(yi)保證，應(ying)用(yong)受到限制。

濕噴(pen)機(ji)采用(yong)混(hun)(hun)凝(ning)土濕噴(pen)技術，很大(da)程度(du)上(shang)解決(jue)了混(hun)(hun)凝(ning)土干(gan)噴(pen)機(ji)存在的(de)諸多問(wen)題，尤(you)其是回彈率低(di)、粉塵濃度(du)低(di)，消(xiao)除了對工(gong)(gong)人健(jian)康的(de)危害，節約了噴(pen)涂(tu)成(cheng)本。而(er)且物料的(de)配合容易(yi)控制，工(gong)(gong)作(zuo)效率高于干(gan)噴(pen)，適用(yong)于各種工(gong)(gong)作(zuo)環境(jing)。

濕(shi)噴機濕(shi)噴混(hun)(hun)(hun)凝(ning)土(tu)(tu)的(de)施工(gong)工(gong)藝是在水(shui)泥混(hun)(hun)(hun)凝(ning)土(tu)(tu)攪拌站(zhan)按配(pei)合比生產(chan)出成品混(hun)(hun)(hun)凝(ning)土(tu)(tu)，將混(hun)(hun)(hun)凝(ning)土(tu)(tu)運輸到(dao)工(gong)作面(mian)，然(ran)后用混(hun)(hun)(hun)凝(ning)土(tu)(tu)濕(shi)噴機將其壓到(dao)噴嘴處，在噴嘴處加入速(su)凝(ning)劑后進行高(gao)速(su)噴射。在高(gao)速(su)噴射過程中(zhong)，混(hun)(hun)(hun)凝(ning)土(tu)(tu)與速(su)凝(ning)劑充分結(jie)合，沖擊圍巖，形成混(hun)(hun)(hun)凝(ning)土(tu)(tu)支撐層。

濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)是濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)凝(ning)(ning)(ning)土施工的核心設備。常見的混(hun)凝(ning)(ning)(ning)土濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)包括小型濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)、液壓濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)、轉(zhuan)子濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)、車(che)載濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)和(he)濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)機(ji)(ji)(ji)(ji)(ji)械(xie)手。隨著人們環保意識的增強和(he)對(dui)噴(pen)(pen)(pen)(pen)(pen)(pen)射混(hun)凝(ning)(ning)(ning)土質(zhi)量(liang)要(yao)(yao)求(qiu)的提(ti)高，越來越多的工程要(yao)(yao)求(qiu)使(shi)用(yong)混(hun)凝(ning)(ning)(ning)土濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)(ji)(ji)(ji)(ji)。隨著濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)凝(ning)(ning)(ning)土機(ji)(ji)(ji)(ji)(ji)械(xie)及相(xiang)關材料設備生產技術的不斷進步，濕(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)凝(ning)(ning)(ning)土將作為(wei)一(yi)種成(cheng)熟的施工技術得到廣泛應(ying)用(yong)。
