Construction method of bridge pile foundation on expressway
The invention discloses a construction method of a bridge pile foundation on an expressway, which comprises the following steps: before machinery enters construction, a constructor needs to level a construction site in advance; pile position measurement; embedding a pile casing; drilling mud; manufacturing reinforcing steel bars; and performing construction control in the underwater concrete pouring process. According to the construction method of the bridge pile foundation on the expressway, the positioning steel bars are welded on the framework main bars, the interval positions are determined according to the size of the steel bar cage and the structure of the framework, so that the control effect on a protective layer is improved, concrete needs to be mixed through an automatic mixing machine, the mixing temperature is controlled moderately, and the construction efficiency is improved. Wherein the low temperature can cause non-uniform mixing of the concrete and influence on the use performance, and the overhigh temperature can cause aging of the concrete, so that the heating process needs to be completed in one step, the conditions of repeated heating and heating interruption are avoided, and the temperature is actually controlled in combination with the influence effect of seasons and weather, so that the use performance of the concrete is exerted to the greatest extent.
本发明公开了一种高速公路上桥梁桩基的施工方法，包括以下步骤：机械进入施工前，施工人员要提前平整施工场地；桩位测量；埋设护筒；钻孔泥浆；钢筋的制作；水下混凝土灌注过程的施工控制。该高速公路上桥梁桩基的施工方法，在骨架主筋上进行定位钢筋的焊接，对于间隔位置的确定要根据钢筋笼的大小及骨架的结构来确定，从而提高对保护层的控制效果，对于混凝土的拌和需要采用自动拌合机进行，拌和温度控制适中，其中温度低会使混凝土拌和不均匀，使用性能受到影响，而温度过高则会使混凝土老化，因此加热过程要一步到位，避免重复加热和加热中断的情况，并结合季节和天气影响作用，对温度进行实际的控制，使得最大程度发挥混凝土使用性能。
