以内。为确保桩顶质量，根据高铁技术标准，在桩顶设计标高以上加灌 1 米以上高度，以便保证混凝土强度，多余部分接桩前凿除，桩头应无松散层。6、灌注水下混凝土时，随时探测钢护筒顶面以下的剩余孔深并计算所灌注的混凝土的高度，以便控制导管埋入深度和桩顶标高。测锤法：用绳系重锤吊入孔中，使之通过泥浆沉淀层而停留在混凝土表面，根据测绳所示锤的沉入深度换算出混凝土的灌注深度。7、在混凝土灌注过程中，要防止混凝土拌和物从漏斗溢出或从漏斗外掉入孔底，使泥浆内含有水泥而变稠凝固，致使测深不准。同时应设专人注意观察导管内混凝土下降和井孔水位上升，及时测量复核孔内混凝土面高度及导管埋入混凝土的深度，做好详细的混凝土施工灌注记录，正确指挥导管的提升和拆除。探测时必须仔细，同时以灌入的混凝土数量校对，防止错误。8、施工中导管提升时应保持轴线竖直和位置居中，逐步提升。拆除导管动作要快，拆装一次时间一般不宜超过 15min。要防止螺栓、橡胶垫和工具掉入孔中，要注意安全。已拆下的导管要立即清洗干净，堆放整齐。9、控制混凝土灌注速度及方法：灌注混凝土时，随时掌握混凝土灌注高程及导管埋深，当混凝土埋过钢筋笼 23 米时，才将导管提至钢筋笼底端以上。10、当混凝土灌注到接近钢筋骨架下端时，为防钢筋骨架被混凝土顶托上升，可采取以下措施：导管底口处于钢筋笼底口上下 3m 时，放慢混凝土浇筑速度，减少混凝土面上升的动能作用，以免钢筋笼顶被托而上浮；当混凝土超过钢筋笼底 2 米左右时，适当提升导管，减少导管埋置长度，使导管底口处于钢筋笼底口附近，并加快浇注速度，以增加钢筋笼的埋置深度，从而增加混凝土对钢筋骨架的握裹力；thrift of excellent traditional and style lack deep of
