Description
Technical Field
[0001] This utility model relates to the technical field of foundation pile construction support equipment, specifically to a support structure for large-diameter bridge pile foundation construction in steep river channels. Background Technology
[0002] Against the backdrop of the continuous advancement of modern transportation infrastructure construction, large-diameter bridges, as key engineering structures spanning rivers, canyons, and other complex terrains, are seeing a rapid increase in their scale and number. Large-diameter bridge piles, serving as the foundation of the bridge, bear the crucial responsibility of transferring the load of the superstructure to deep, stable soil or rock layers. Their construction quality directly affects the overall stability, durability, and operational safety of the bridge.
[0003] When constructing large-diameter bridge pile foundations in steep riverbeds, the complex construction environment and variable geological conditions mean that traditional support structures lack effective positioning and adjustment mechanisms during installation. This makes it difficult to accurately determine the installation position and angle of support components, resulting in difficulty in ensuring the construction accuracy of the foundation piles. Consequently, problems such as pile displacement and tilting can easily occur, affecting the overall structural safety and stability of the bridge.
[0004] To address the aforementioned issues, we propose a support structure for the construction of large-diameter bridge pile foundations in steep riverbeds. Utility Model Content

[0007] Preferably, the top outer wall of the fan-shaped base plate is fixedly provided with an arc-shaped guide rail, and the outer wall of the two large-diameter semi-arc support plates includes a standard ring, the outer wall of the standard ring being engaged with the inner wall of the arc-shaped guide rail.
[0008] Preferably, the top outer wall of the fan-shaped base plate has two positioning holes, the inner walls of the two positioning holes are equipped with matching bolts, and the bottom outer wall of the fan-shaped base plate is fixed with anti-slip teeth distributed at equal intervals.

[0010] Preferably, both the large-diameter semi-circular support plate and the fan-shaped base plate are forged from steel plate material.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0012] By using a fan-shaped base plate, the outer wall of a standard circular ring is inserted into the inner wall of an arc-shaped guide rail. The position of the fan-shaped base plate is adjusted and laid out into a circular structure. Then, two large-diameter semi-arc support plates are hoisted to the pile foundation construction location on a steep river slope, so that the slots are engaged with the inner wall of the guide rail and the outer wall of the positioning strip. At the same time, two horizontal plates are supported on the top of the guide rail. The large-diameter semi-arc support plates are placed in the middle of the circularly distributed fan-shaped base plates. By arranging the fan-shaped base plates first and adjusting their levelness, the accuracy of the installation position and angle of the large-diameter semi-arc support plates can be improved.
