Construction method for sunken pedestal of pre-tensioning prestressed concrete beam
The invention discloses a construction method for a sunken pedestal of a pre-tensioning prestressed concrete beam, which belongs to the technical field of bridge construction and comprises the following steps: step 1, leveling a beam field and tamping a foundation, step 2, excavating a beam-making pedestal after surveying and paying off, the method comprises the following steps of 1, carrying out concrete hardening on the positions of a transmission stand column and a beam making pedestal, 2, mounting a steel cross beam according to measurement positioning, 3, constructing the transmission stand column and a connection beam to fix a steel box beam in the transmission stand column, and 6, carrying out beam making pedestal construction. The beam-making pedestal originally located above the ground is arranged below the ground, the sunken prestressed concrete beam-making pedestal is formed by combining the beam-making pedestal with the frame-type transmission stand column, and the in-site road is constructed above the transmission stand column, so that a concrete tank car can be directly driven to the prestressed concrete beam to dump concrete through the chute; not only is the investment of a small gantry crane saved, but also the concrete pouring efficiency is greatly improved.
本发明公开了一种先张法预应力混凝土梁下沉式台座施工方法，属于桥梁建设技术领域，包括以下步骤：步骤一、平整梁场场地并夯实基础，步骤二、测量放线后开挖制梁台座，开挖深度为预制梁梁体高度，步骤三、传立柱及制梁台座位置进行混凝土硬化，步骤四、按照测量定位安装钢横梁，步骤五、施工传立柱及联系梁，使钢箱梁固定于传立柱中，步骤六、制梁台座施工。将原本位于地面以上的制梁台座设置于地面以下，并结合框架式的传立柱形成一种下沉式的预应力混凝土制梁台座，在传立柱上方施工场内道路，使混凝土罐车可直接开至预应力混凝土梁上通过溜槽自卸混凝土，不仅节省了小龙门吊的投入，还极大的增加了混凝土浇筑效率。
