履帶式液壓鉆機的固定與安裝

履(lv)帶式液壓鉆機(ji)(ji)通常有三種固(gu)定(ding)方法(fa)：地錨(mao)(mao)(mao)(mao)(mao)(mao)、基(ji)(ji)礎和(he)護(hu)堤。固(gu)定(ding)前，檢查(cha)加固(gu)施工現場(chang)支護(hu)情況，清(qing)理現場(chang)，保(bao)(bao)持(chi)(chi)底(di)(di)(di)板平整(zheng)，保(bao)(bao)持(chi)(chi)后(hou)路暢通，保(bao)(bao)持(chi)(chi)通風、排水、供電、供水、供風等系(xi)統完好完整(zheng)，確(que)定(ding)洞口高度(du)(du)(du)及(ji)左右位置(zhi)(zhi)(zhi)，鉆孔方向(xiang)，角度(du)(du)(du)等參數(shu)，然(ran)(ran)后(hou)確(que)定(ding)鉆機(ji)(ji)的(de)固(gu)定(ding)位置(zhi)(zhi)(zhi)并固(gu)定(ding)。使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)地錨(mao)(mao)(mao)(mao)(mao)(mao)時(shi)，要準確(que)跟蹤底(di)(di)(di)座錨(mao)(mao)(mao)(mao)(mao)(mao)孔的(de)尺(chi)(chi)寸和(he)位置(zhi)(zhi)(zhi)，然(ran)(ran)后(hou)鉆錨(mao)(mao)(mao)(mao)(mao)(mao)孔，安裝錨(mao)(mao)(mao)(mao)(mao)(mao)栓(shuan)(shuan)(shuan)(shuan)(shuan)，使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)全螺(luo)紋錨(mao)(mao)(mao)(mao)(mao)(mao)栓(shuan)(shuan)(shuan)(shuan)(shuan)，直徑(jing)不小于(yu)(yu)22mm，長(chang)度(du)(du)(du)不小于(yu)(yu)1500，然(ran)(ran)后(hou)吊(diao)(diao)起(qi)鉆機(ji)(ji)，對準底(di)(di)(di)座錨(mao)(mao)(mao)(mao)(mao)(mao)孔用(yong)(yong)(yong)(yong)(yong)地腳螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)將(jiang)底(di)(di)(di)座慢慢放下。每(mei)(mei)個(ge)(ge)錨(mao)(mao)(mao)(mao)(mao)(mao)定(ding)螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)用(yong)(yong)(yong)(yong)(yong)兩個(ge)(ge)螺(luo)母(mu)擰緊。使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)基(ji)(ji)礎時(shi)，基(ji)(ji)礎深度(du)(du)(du)不應(ying)小于(yu)(yu)1500毫米，長(chang)度(du)(du)(du)和(he)寬度(du)(du)(du)應(ying)根(gen)據鉆機(ji)(ji)底(di)(di)(di)座的(de)尺(chi)(chi)寸來確(que)定(ding)。澆筑混凝土時(shi)，根(gen)據底(di)(di)(di)座錨(mao)(mao)(mao)(mao)(mao)(mao)孔尺(chi)(chi)寸預(yu)埋錨(mao)(mao)(mao)(mao)(mao)(mao)栓(shuan)(shuan)(shuan)(shuan)(shuan)或螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)，然(ran)(ran)后(hou)吊(diao)(diao)裝鉆機(ji)(ji)，將(jiang)底(di)(di)(di)座錨(mao)(mao)(mao)(mao)(mao)(mao)孔與(yu)錨(mao)(mao)(mao)(mao)(mao)(mao)栓(shuan)(shuan)(shuan)(shuan)(shuan)或螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)對準，緩慢下放錨(mao)(mao)(mao)(mao)(mao)(mao)栓(shuan)(shuan)(shuan)(shuan)(shuan)。每(mei)(mei)個(ge)(ge)錨(mao)(mao)(mao)(mao)(mao)(mao)定(ding)螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)或螺(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)應(ying)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)兩個(ge)(ge)螺(luo)母(mu)擰緊。使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)護(hu)道時(shi)，立(li)(li)柱(zhu)數(shu)量不少于(yu)(yu)4根(gen)，護(hu)道立(li)(li)柱(zhu)數(shu)量不少于(yu)(yu)2根(gen)；使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)內外(wai)注(zhu)式單(dan)柱(zhu)液壓支柱(zhu)時(shi)，應(ying)將(jiang)其(qi)吊(diao)(diao)起(qi)壓牢(lao)；使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)木柱(zhu)時(shi)，應(ying)用(yong)(yong)(yong)(yong)(yong)木楔將(jiang)其(qi)擰緊。

利用履帶式(shi)液壓鉆(zhan)機(ji)進(jin)行(xing)探(tan)排水(shui)(shui)(shui)時(shi)，固(gu)定鉆(zhan)孔點距(ju)積水(shui)(shui)(shui)區(qu)的(de)距(ju)離小于規定的(de)探(tan)水(shui)(shui)(shui)超(chao)前距(ju)離，或(huo)有(you)突水(shui)(shui)(shui)跡(ji)象的(de)，應采取(qu)加固(gu)措施(shi)或(huo)關閉水(shui)(shui)(shui)門端部，然后再找一個安全的(de)地方進(jin)行(xing)探(tan)水(shui)(shui)(shui)和排水(shui)(shui)(shui)。鉆(zhan)探(tan)場地應避開斷層帶或(huo)軟弱(ruo)巖層。鉆(zhan)機(ji)必須(xu)固(gu)定牢固(gu)。鉆(zhan)機(ji)安裝通電(dian)時(shi)，應嚴格執行(xing)停電(dian)送電(dian)制度。按預期流(liu)量(liang)修(xiu)建排水(shui)(shui)(shui)溝(gou)，清理道路，懸(xuan)掛風管、電(dian)纜、管道等。
