F、燈頭箱、過路箱澆搗在混凝土內(nèi)的，管口要用封口護(hù)卷封好，箱子用不易腐爛的東西塞住，防止混凝土或灰漿進(jìn)入管子內(nèi)或箱子內(nèi)。
Lamp box, crossing at ramming me pouring concrete, and retaining possession of the mouth to use sealing closure volume, and a box with something non-perishable stuff to prevent the concrete or mortar into the tube or box
 
G、電管的彎頭應(yīng)用符合要求的彎管或現(xiàn)場彎制，彎曲處不得產(chǎn)生皺裂現(xiàn)象，橢圓度不得超過管徑的+10%，彎曲半徑應(yīng)符合下列要求：
Application of electric pipe bend to meet the requirements of the pipe or field bends the system may not have a wrinkle bend cracking phenomenon, ovality must not exceed +10% diameter, bending radius shall meet the following requirements
 
H、當(dāng)敷設(shè)轉(zhuǎn)角處的暗管時，應(yīng)不小于管外徑的6倍。
When the laying of underground pipe corner should be not less than 6 times the pipe outside diameter
 
I、當(dāng)敷設(shè)在平地下或混凝土樓板內(nèi)時，應(yīng)不小于管外徑的8倍。
When laying flat at the ground floor or concrete floor when it should be not less than 8 times the pipe outside diameter.
 
J、在土建砌磚墻前先做好磚墻內(nèi)的配管工作，如果個別管子未放進(jìn)磚墻內(nèi)，或圖紙修改增加的管子需鑿墻面的，不得大范圍破壞墻體，可用開槽機(jī)開槽，管子及箱盒敷設(shè)后應(yīng)用100#水泥砂漿固定，保護(hù)層不應(yīng)小于15mm。
At block brick wall construction brick wall before they do a good job within the piping job, if not into the brick walls of individual tubes, or drawings to be modified to increase the hammer and the wall of the tube, it may not be large-scale destruction of the wall, slotting machine can be used to open chutes, tubes and boxes after the laying of the application of 100 # cement mortar fixed, protective layer should be not less than 15mm
 
K、所有暗敷配管和明敷配管的跨接均應(yīng)牢固可靠。
Concealed tubing and open tubing shall be secured and reliable.
