樁基礎施工測量

高程測(ce)(ce)(ce)量(liang)：高程引測(ce)(ce)(ce)之前首先(xian)要設置水(shui)準(zhun)(zhun)點，設置的(de)原則主要是便(bian)于(yu)保存與使(shi)用(yong)，數量(liang)上一般(ban)于(yu)多余2~3個(ge)。待(dai)設置水(shui)準(zhun)(zhun)點完(wan)成(cheng)后，高程測(ce)(ce)(ce)量(liang)應(ying)該按(an)照四等水(shui)準(zhun)(zhun)測(ce)(ce)(ce)量(liang)方(fang)法和要求進(jin)行(xing)，其往(wang)返較(jiao)差，附合(he)或環線閉合(he)差不應(ying)大(da)于(yu)20L，L為(wei)水(shui)準(zhun)(zhun)路(lu)線長度，單位為(wei)km，樁位點高程測(ce)(ce)(ce)量(liang)的(de)測(ce)(ce)(ce)量(liang)方(fang)法一般(ban)為(wei)普(pu)通水(shui)準(zhun)(zhun)儀散點法，誤(wu)差上不應(ying)超(chao)過1cm。

建筑(zhu)(zhu)物(wu)軸線測(ce)設：根據設計圖紙上(shang)注明的(de)測(ce)量控制點或基(ji)(ji)準(zhun)(zhun)線來進行建筑(zhu)(zhu)物(wu)樁基(ji)(ji)礎的(de)定位(wei)測(ce)量，通常取決(jue)于項目(mu)設計所提(ti)供的(de)測(ce)量控制點或基(ji)(ji)準(zhun)(zhun)線與新建筑(zhu)(zhu)物(wu)的(de)相關數(shu)據來進行，順序上(shang)首先測(ce)設建筑(zhu)(zhu)物(wu)定位(wei)矩形控制網，然后(hou)測(ce)設建筑(zhu)(zhu)物(wu)樁位(wei)軸線，后(hou)測(ce)設承(cheng)臺樁位(wei)。

測量質量控制

在(zai)架(jia)設建(jian)筑物定位矩形網點的過程中，要埋設直(zhi)徑為8cm，長度為35cm的木樁(zhuang)，埋設的位置(zhi)首先(xian)要便于(yu)作業(ye)，12米擠(ji)密樁(zhuang)基施工，其次要便于(yu)保存，建(jian)議在(zai)木樁(zhuang)上的中心位置(zhi)做好標(biao)記，木樁(zhuang)要使用水(shui)泥做加(jia)固保護，并定期做安(an)全檢查(cha)。

對于工期較長或(huo)規模較大的工程應該埋(mai)設頂部為(wei)10cm×10cm，底部為(wei)12cm×12cm，長80cm的水(shui)泥樁(zhuang)作(zuo)為(wei)長期控(kong)制點。

必須加強檢查(cha)工作，包括樁位測(ce)量(liang)(liang)(liang)放線圖的(de)(de)所有計算數(shu)據。必須經第二個人進(jin)(jin)行的(de)(de)檢查(cha)，確認(ren)無(wu)誤后才(cai)能到現場(chang)測(ce)設。在建筑(zhu)物(wu)定(ding)位測(ce)量(liang)(liang)(liang)成(cheng)果經檢查(cha)滿足(zu)要求后，才(cai)能測(ce)設建筑(zhu)物(wu)樁位軸線進(jin)(jin)行建筑(zhu)物(wu)的(de)(de)定(ding)位測(ce)量(liang)(liang)(liang)。
