图（6）中L为底盘宽度，E为立柱上平面中心、E1为底盘中心。底盘半对角线根开值OE1=OE+EE1；

上式中OE为基础根开值，EE1为立柱上平面中心沿对角线方向偏离底盘中心值；

EE1=√2 a （a值设计已给出）

确定OE1值后，根据基础型式可求出OB、OD的值，用尺则可定出A、C点位置。

7.2基础坑开挖及检查

基础坑根据地质情况，采用人工开挖或爆破开挖，基坑开挖完后，必须对坑位方向、距离、坑口上、下部尺寸和坑深进行检查，避免尺寸不符合设计要求而影响施工。 7.3测量方法

塔腿基础顶面高差往往较大，基础分坑定位时，一般采用角度测斜距的方法：经纬仪支于线路中心桩上，沿线路方向转45°测出该点对另一点的垂直角α，用钢皮尺直接量出仪器中心点到该点的斜距S，再计算出水平距离L[见图（7）]： L=S×cosα

L 图(7) 当测量方向上有凸物，不通视时，一般通过多次分段测量再累计的方法确定距离；障碍物不是很高，地质为土或土夹石时，建议开测量槽，因为分段测量，移动仪器，误差随之增大。 7.4主角钢插入式基础定位控制桩的钉立

控制桩必须钉在坑中附近且不易被撞动的地方，控制桩的高度必须保证为主角钢露出高+200mm以上的操作高度；见控制桩示意图（8），其中A、B、C、D、E、F六个桩均应操平，G为立柱顶部中心；A、B、C、D四个桩用来控制立柱顶部模板位置。E、F桩控制主角钢的位置尺寸及倾斜。

图（9）图（10） E2 图中O为铁塔中心，E为角钢顶点，E1为角铁背露出基础立柱上平面点的位置，E2为角钢背延伸至底盘与坑底交点位置。H为主角露出基础的长度。图中a1=基础半根开+A值（见图3），b值须根据主角钢的倾斜率和主角钢露出基础顶面的长度（设计给出）确定，因角钢的倾斜与基础是一致的，所以b=a1－H×COSα，α角即为立柱侧面平行四边形下底边和斜边的夹角见图（1）。C=底盘半根开+A值，

根据a1、b的值，进而可以确定OE、OE1，从而控制主角钢的几何尺寸。 7.6安装固定插入式主角钢

采用插入式角钢下端延长，上端固定于坑口的施工方法 7.6.1施工准备

7.6.1.1为保证插入式角钢底部不致于陷入泥土或垫层中，在坑底放一预制混凝土垫块，作为插入式角钢的支撑点，垫块大小视主角钢重量而定。 7.6.1.2接长插入式角钢。因主角钢距基础底面标高一般有一段距离，为使主角钢直接落到基础底部，需接长一规格为∠63×5mm的角钢或φ50的钢管（根据具体基础型式计算出其长度）。接长的角钢或钢管要求与主角钢基本保

持同一直线。另在接长角钢或钢管底部焊一可调螺栓M16×55，用以调整坑底标高误差。

7.6.1.3当底部角钢控制好后，调整角钢顶部，使其符合质量要求。 a先移动角钢顶部，使其顶部与根开控制相差约50mm以内

b分别在坑的外侧大致与主角钢相平的位置，用0.5m长的角钢打入地里，一定要牢固，角钢的位置应考虑小角钢的长度。

c把小角钢用螺栓与主角钢连接在一起，调整花兰螺丝，使角钢背与根开控制点重合，在校对角钢时应注意以下事项：角钢的双面坡度、根开、高差。角钢之间高差超标，低的可用底脚调节螺丝调高，严禁用锤击角钢顶部。花兰螺丝与插入角钢连接两角钢可伸缩打入地下角钢图11角钢调正固定工具连接示意图
