混(hun)凝(ning)土(tu)(tu)噴(pen)漿(jiang)(jiang)機是噴(pen)錨(mao)支護作業的(de)(de)主(zhu)要設備，它(ta)利用壓縮(suo)空氣將按一(yi)定級配和水灰比拌制的(de)(de)混(hun)凝(ning)土(tu)(tu)通過(guo)噴(pen)漿(jiang)(jiang)機噴(pen)嘴高速噴(pen)射，從而在噴(pen)射面上形成(cheng)混(hun)凝(ning)土(tu)(tu)支撐層。混(hun)凝(ning)土(tu)(tu)噴(pen)射混(hun)凝(ning)土(tu)(tu)機廣泛應用于(yu)與建筑、市政、鐵路公(gong)路隧道(dao)、基坑、礦山、邊坡等相關的(de)(de)噴(pen)射混(hun)凝(ning)土(tu)(tu)支護工(gong)程。

混凝(ning)土(tu)(tu)(tu)(tu)噴(pen)漿(jiang)(jiang)機(ji)分為干式(shi)噴(pen)漿(jiang)(jiang)機(ji)和混凝(ning)土(tu)(tu)(tu)(tu)濕式(shi)噴(pen)漿(jiang)(jiang)機(ji)。干噴(pen)機(ji)采用干噴(pen)技術。噴(pen)射(she)混凝(ning)土(tu)(tu)(tu)(tu)時粉塵污(wu)染和回彈嚴重(zhong)，空氣質(zhi)量(liang)差，用水量(liang)控制不準確，混凝(ning)土(tu)(tu)(tu)(tu)強度難以保(bao)證，應(ying)用受到限制。

濕噴機(ji)采(cai)用混凝(ning)土濕噴技術，很大(da)程度上解(jie)決了(le)混凝(ning)土干(gan)噴機(ji)存(cun)在的諸多(duo)問(wen)題，尤其是回(hui)彈率(lv)低、粉(fen)塵(chen)濃度低，消除了(le)對(dui)工人(ren)健康(kang)的危害，節約了(le)噴涂成本。而(er)且物料(liao)的配合容易(yi)控(kong)制，工作效(xiao)率(lv)高(gao)于(yu)干(gan)噴，適用于(yu)各種工作環境。

濕(shi)噴(pen)(pen)機濕(shi)噴(pen)(pen)混凝(ning)(ning)土(tu)的施工工藝(yi)是在(zai)水(shui)泥混凝(ning)(ning)土(tu)攪拌站按配合比生產(chan)出成品混凝(ning)(ning)土(tu)，將(jiang)混凝(ning)(ning)土(tu)運輸到工作面，然后(hou)用混凝(ning)(ning)土(tu)濕(shi)噴(pen)(pen)機將(jiang)其(qi)壓到噴(pen)(pen)嘴處，在(zai)噴(pen)(pen)嘴處加入速凝(ning)(ning)劑后(hou)進(jin)行高速噴(pen)(pen)射。在(zai)高速噴(pen)(pen)射過程中，混凝(ning)(ning)土(tu)與速凝(ning)(ning)劑充(chong)分結合，沖擊圍巖，形成混凝(ning)(ning)土(tu)支撐層。

濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)是(shi)濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)(hun)(hun)凝(ning)土(tu)施(shi)工(gong)(gong)的(de)核心(xin)設(she)備(bei)(bei)。常見的(de)混(hun)(hun)(hun)凝(ning)土(tu)濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)包括小型濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)、液壓濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)、轉子濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)、車(che)載濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)和濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)機(ji)械手。隨(sui)著人(ren)們環保(bao)意(yi)識(shi)的(de)增強和對噴(pen)(pen)(pen)(pen)(pen)(pen)射混(hun)(hun)(hun)凝(ning)土(tu)質量要求(qiu)的(de)提(ti)高(gao)，越來越多的(de)工(gong)(gong)程要求(qiu)使用混(hun)(hun)(hun)凝(ning)土(tu)濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)機(ji)。隨(sui)著濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)(hun)(hun)凝(ning)土(tu)機(ji)械及相關材料設(she)備(bei)(bei)生產技(ji)術(shu)的(de)不斷進步，濕(shi)(shi)噴(pen)(pen)(pen)(pen)(pen)(pen)混(hun)(hun)(hun)凝(ning)土(tu)將作為一種成(cheng)熟(shu)的(de)施(shi)工(gong)(gong)技(ji)術(shu)得到廣泛應用。
