Embodiment Construction
[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0053] Such as Figure 1-Figure 13 Shown, the cast-in-place box girder construction method is characterized in that: comprises the following steps:
[0054] 1. Construction preparation:
[0055] Carry out the construction of bridge pier column 1 and its lower load-bearing structure, determine the concrete mix ratio, and prepare the devices required for construction;
[0056] 2. Layout of cast-in-place box girder support system:
[0057] On the foundation soil 2 on both sides of the bridge pier column 1, a foundation cushion 3 and a prefabricated foundation 4 are arranged in sequence from bottom to top, wherein each prefabricated foundation 4 is composed of two parts that are superimposed and connected by step slopes, and The two parts of the prefabricated foundation 4 that are superimposed and connected up and down are firmly connected through the fo...
