The invention relates to the technical field of connection structure between prefabricated bridge pier columns and caps, and discloses a construction method for hollow bridge pier columns and caps. The length direction of the prefabricated bridge pier column, and build the cap for fixing the bridge pier column; the bridge pier column includes the upper supporting section and the lower embedded section, along the circumferential direction around the prefabricated bridge pier column, along the outer wall of the embedded section Dig inward to form the first notch; during the process of building the cap, reserve a fixed groove with the opening facing upward in the middle of the cap; hoist the bridge pier column, and lower the embedded section of the bridge pier column into the fixed groove; Finally, concrete is poured into the cavity of the bridge pier column and the first notch; the tight connection between the prefabricated bridge pier column and the cap is realized, and the connection between the prefabricated bridge pier column and the cap is located inside the cap, which is not easily damaged The interference of wind blowing and water erosion has stronger shear and earthquake resistance.
Description
technical field [0001] The patent of the present invention relates to the technical field of the connection structure between the prefabricated bridge pier column and the cap, and specifically relates to the construction method of the hollow bridge pier column and the cap. Background technique [0002] The bridge pier is the middle structure of the bridge except the bridge abutment connecting the two ends with the embankment, which is used to support the bridge. [0003] At present, the bridge piers of urban bridges are usually constructed by cast-in-place construction, and the road surface needs to be blocked during construction, which directly affects the road traffic capacity of the construction point. The quantity is large and the construction cost is high, which is incompatible with the requirements of urban construction and development. [0004] By adopting the construction method of prefabricating the bridge pier columns in the prefabricated factory and directly conn...
