  赣州钢护桶出租公司解析钢护桶的用途

  钢(gang)护(hu)(hu)(hu)筒(tong)就是(shi)在进(jin)行人工挖孔(kong)桩(zhuang)的(de)(de)过程中,由于土(tu)质不稳(wen)定,施工钢(gang)筋混(hun)凝土(tu)护(hu)(hu)(hu)壁存在较大(da)(da)难度(du)所(suo)以采用钢(gang)质的(de)(de)护(hu)(hu)(hu)壁对孔(kong)桩(zhuang)进(jin)行保护(hu)(hu)(hu),防(fang)(fang)止(zhi)塌孔(kong)避免影响施工进(jin)度(du)及安全(quan)。钢(gang)护(hu)(hu)(hu)筒(tong)就是(shi)根据孔(kong)桩(zhuang)的(de)(de)大(da)(da)小用铁(tie)皮箍成的(de)(de)一(yi)个圆形的(de)(de)两头都是(shi)空的(de)(de)桶。能稳(wen)定孔(kong)壁,防(fang)(fang)止(zhi)坍孔(kong),还可(ke)以隔离地表水,导向钻头,固(gu)定桩(zhuang)位,保护(hu)(hu)(hu)操作原(yuan)地面等,一(yi)般比桩(zhuang)径大(da)(da)20-40cm,埋置深度(du)视土(tu)的(de)(de)性状而定,平面位置的(de)(de)偏差不得大(da)(da)于5cm,倾斜度(du)小于1%。

  用(yong)于钻孔(kong)灌注桩施工作(zuo)(zuo)业,为钢材(cai)制(zhi)作(zuo)(zuo),圆柱(zhu)状。一(yi)般为钢护筒,壁厚10mm。一(yi)般作(zuo)(zuo)为施工预防固定作(zuo)(zuo)用(yong)。护筒连接处要求筒内无突出(chu)物,应耐拉(la)、压,不(bu)漏水。

  在钻(zuan)孔(kong)灌注(zhu)桩中(zhong),常(chang)埋(mai)设钢(gang)(gang)护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)来定位(wei)需要(yao)钻(zuan)的桩位(wei)。护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)为钢(gang)(gang)护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong),壁厚10mm,护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)定位(wei)时(shi),先以(yi)桩位(wei)中(zhong)心(xin)为圆(yuan)心(xin),根据(ju)护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)半径在土(tu)(tu)上定出护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)位(wei)置(zhi),护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)就位(wei)后,施(shi)加压(ya)力将护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)埋(mai)入(ru)(ru)约50cm。如下(xia)压(ya)困难,可先将孔(kong)位(wei)处的土(tu)(tu)体挖(wa)出一(yi)部分,然后安(an)放护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)埋(mai)入(ru)(ru)地下(xia)。在埋(mai)入(ru)(ru)过程中(zhong)应检查(cha)护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)是否(fou)垂直,若发现(xian)偏斜,应及(ji)时(shi)纠(jiu)正(zheng)。陆上护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)埋(mai)放就位(wei)后,将护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)外侧(ce)用(yong)粘(zhan)土(tu)(tu)回(hui)填(tian)压(ya)实,以(yi)防止护(hu)(hu)(hu)(hu)(hu)(hu)(hu)筒(tong)(tong)(tong)四周出现(xian)漏水现(xian)象,回(hui)填(tian)厚度约40-45cm,顶端高度高出(水面)地面0.4-0.6m, 筒(tong)(tong)(tong)位(wei)距孔(kong)心(xin)偏差不得大于50mm。

  钢护桶用(yong)途是(shi):

1、可以有(you)效定位;

2、保护孔(kong)口,以及防止地(di)面石(shi)块掉入孔(kong)内;

3、保持泥浆水(shui)位(压力),防止坍孔;

4、桩(zhuang)顶标高控制依据之一;

5、防止钻(zuan)孔过程中的(de)沉渣回(hui)流。
