Landslide is a geological hazard with serious losses . it is very important to research the controling methods . slide - resistant pile , which has many advantages such as high adaptability , little interference to landslide and geological environment , short construction time , high silde resistance , is a main method to control landslide . pneumatic down - the - hole hammer is a drilling method with many advantages . its features , such as wide application range , high hole quality , no circulating medium , low operation regulations , and drilling big diameter rock hole , fit to construct slide - resistant pile . according to the requirement of silde - resistant pile construction , this paper analyses feasibility that pneumatic dth hammer drilling applies to construct slide - resistant pile on the basis of introducing the features of pneumatic dth hammer . then an applied example is given 滑坡是一種危害極大的地質(zhì)災(zāi)害,它的整治方法研究具有重要意義.抗滑樁是一種適應(yīng)性強(qiáng)、對(duì)滑坡穩(wěn)定性和地質(zhì)環(huán)境干擾小、工期短、抗滑能力強(qiáng)的滑坡整治方法.風(fēng)動(dòng)潛孔錘鉆進(jìn)是一種具有許多優(yōu)點(diǎn)的鉆進(jìn)方法,它的許多特點(diǎn),如成孔質(zhì)量高、應(yīng)用范圍廣、無(wú)液體循環(huán)介質(zhì)、鉆進(jìn)規(guī)程參數(shù)小、可實(shí)現(xiàn)大直徑基巖鉆孔等都適合于抗滑樁施工.文章在介紹風(fēng)動(dòng)潛孔錘鉆進(jìn)特點(diǎn)的基礎(chǔ)上,根據(jù)抗滑樁施工要求,分析了風(fēng)動(dòng)潛孔錘用于抗滑樁施工的可行性,并舉出了其應(yīng)用實(shí)例
