混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)噴(pen)(pen)(pen)漿機是(shi)噴(pen)(pen)(pen)錨(mao)支護作業(ye)的主要設備，它利用壓縮空氣(qi)將按一定級配和水灰比(bi)拌(ban)制(zhi)的混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)通過噴(pen)(pen)(pen)漿機噴(pen)(pen)(pen)嘴高速(su)噴(pen)(pen)(pen)射(she)，從而在噴(pen)(pen)(pen)射(she)面(mian)上形(xing)成混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)支撐層(ceng)。混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)噴(pen)(pen)(pen)射(she)混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)機廣(guang)泛應用于與建(jian)筑(zhu)、市政、鐵路公路隧道、基坑、礦山(shan)、邊坡(po)等相關的噴(pen)(pen)(pen)射(she)混(hun)(hun)(hun)(hun)凝(ning)土(tu)(tu)(tu)(tu)支護工程。

混凝(ning)(ning)土噴漿(jiang)機分為(wei)干式噴漿(jiang)機和混凝(ning)(ning)土濕式噴漿(jiang)機。干噴機采用干噴技術。噴射混凝(ning)(ning)土時粉塵污染和回(hui)彈(dan)嚴重，空氣質量差，用水量控制(zhi)不準確(que)，混凝(ning)(ning)土強度難以保證，應用受到限制(zhi)。

濕噴機采用(yong)(yong)混凝土濕噴技(ji)術，很大程度上(shang)解決了混凝土干噴機存(cun)在的諸(zhu)多問題，尤(you)其是回彈率(lv)低、粉塵(chen)濃度低，消(xiao)除了對工人健康的危害(hai)，節約了噴涂(tu)成本。而且物(wu)料的配合容易(yi)控制(zhi)，工作效(xiao)率(lv)高于干噴，適用(yong)(yong)于各種(zhong)工作環境。

濕(shi)噴(pen)(pen)機濕(shi)噴(pen)(pen)混凝(ning)土(tu)(tu)(tu)(tu)的(de)施(shi)工(gong)工(gong)藝(yi)是(shi)在(zai)(zai)水泥混凝(ning)土(tu)(tu)(tu)(tu)攪拌(ban)站按配合比(bi)生產出成品混凝(ning)土(tu)(tu)(tu)(tu)，將(jiang)混凝(ning)土(tu)(tu)(tu)(tu)運輸到(dao)(dao)工(gong)作(zuo)面(mian)，然后用混凝(ning)土(tu)(tu)(tu)(tu)濕(shi)噴(pen)(pen)機將(jiang)其壓(ya)到(dao)(dao)噴(pen)(pen)嘴(zui)處(chu)，在(zai)(zai)噴(pen)(pen)嘴(zui)處(chu)加(jia)入速(su)凝(ning)劑后進行高速(su)噴(pen)(pen)射(she)。在(zai)(zai)高速(su)噴(pen)(pen)射(she)過(guo)程中(zhong)，混凝(ning)土(tu)(tu)(tu)(tu)與速(su)凝(ning)劑充分結合，沖擊圍(wei)巖(yan)，形成混凝(ning)土(tu)(tu)(tu)(tu)支撐層(ceng)。

濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)是濕(shi)(shi)噴(pen)(pen)(pen)混(hun)凝(ning)土(tu)施工(gong)的(de)核心設(she)備(bei)(bei)。常見的(de)混(hun)凝(ning)土(tu)濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)包(bao)括小型濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)、液壓濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)、轉子濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)、車載濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)和濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)機(ji)(ji)(ji)(ji)械(xie)手。隨著(zhu)人們環保意(yi)識的(de)增強(qiang)和對(dui)噴(pen)(pen)(pen)射混(hun)凝(ning)土(tu)質量要求的(de)提高，越來(lai)越多的(de)工(gong)程要求使用混(hun)凝(ning)土(tu)濕(shi)(shi)噴(pen)(pen)(pen)機(ji)(ji)(ji)(ji)。隨著(zhu)濕(shi)(shi)噴(pen)(pen)(pen)混(hun)凝(ning)土(tu)機(ji)(ji)(ji)(ji)械(xie)及相關材料設(she)備(bei)(bei)生產技術的(de)不斷進步(bu)，濕(shi)(shi)噴(pen)(pen)(pen)混(hun)凝(ning)土(tu)將作為一種(zhong)成熟的(de)施工(gong)技術得(de)到(dao)廣泛應用。
