提高水泥(ni)電線桿強度和(he)質量：

一、混凝土(tu)強(qiang)(qiang)(qiang)度(du)：水泥電線桿的離(li)(li)心混凝土(tu)的設(she)(she)計強(qiang)(qiang)(qiang)度(du)不(bu)低于C50級(ji)離(li)(li)心混凝土(tu)的設(she)(she)計強(qiang)(qiang)(qiang)度(du)不(bu)低于C40級(ji)，出廠(chang)時混凝土(tu)強(qiang)(qiang)(qiang)度(du)等(deng)級(ji)應(ying)不(bu)低于設(she)(she)計強(qiang)(qiang)(qiang)度(du)的80%。

二、原(yuan)材料要使用(yong)國標水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)：水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)電線桿應(ying)采(cai)用(yong)不低(di)于42.5MPa的(de)硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、普(pu)通硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、礦(kuang)渣硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)，抗(kang)硫酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、或不低(di)于43.5MPa的(de)快(kuai)硬(ying)硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)，其(qi)性(xing)能應(ying)符(fu)合GB4623-2014規定。采(cai)用(yong)43.5MPa以上(shang)的(de)硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、普(pu)通硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、礦(kuang)渣硅(gui)酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)，抗(kang)硫酸(suan)鹽(yan)水(shui)(shui)(shui)(shui)(shui)(shui)泥(ni)(ni)(ni)(ni)、其(qi)性(xing)能應(ying)符(fu)合GB175、GB199、GB748。

水泥電桿玻璃鋼包裹法，當環繞桿身有數條裂紋或密集細紋、局部酥裂、焊口酥裂時，可使用環氧樹脂玻璃鋼對裂紋與酥裂部位進行包裹。包裹前將原面清理干凈，酥裂部分敲除，并用水泥填補。包裹時刷一層環氧樹脂，包一層玻璃纖維布，每刷裹一層都要將空氣排出，外面一層的環氧樹脂要將玻璃纖維布完全封住，不能有氣泡。使用的環氧樹脂不能過稀，否則不能保證涂刷厚度。玻璃纖維布包裹層數視桿身損壞程度而定，一般不少于3層。此種方法不但對裂紋封(feng)閉嚴密，而(er)且具(ju)有增加強度的作用(yong)。
