一种面板堆石坝的施工结构
By setting horizontal and vertical reinforcing bars on the slipform and combining them with threaded sleeves, steel ropes, and winches, the problem of side form instability caused by vibration during slipform construction was solved, thus achieving stable slipform sliding and high-quality concrete panel forming.

AI Technical Summary
In existing technologies, during the construction of concrete panels for rockfill dams using slipform construction, vibration can easily cause the side formwork to lose stability, making it impossible to effectively maintain the spacing between the two side formworks, resulting in the side formwork opening outwards.
The steel reinforcement body, consisting of horizontal and vertical bars, is connected to the side formwork via bolt sleeves. Combined with steel ropes, winches, and guide supports, it forms a stable load-bearing structure, ensuring the stability of the sliding formwork when it slides on the side formwork.
It effectively prevents the slipform from opening outward under external load, maintains the stability of the side formwork, and ensures the forming quality of the concrete panel.

Abstract
Claims
1. A construction structure of a face rockfill dam, characterized by, include: Two relatively spaced side molds (3) are distributed on the water-facing side of the rockfill dam (1), and there is a space between the two side molds (3) for the concrete panel (2) to be cast. A transverse bar (31) and a longitudinal bar (32) are distributed between the two side molds (3); the transverse bar (31) and the longitudinal bar (32) are arranged vertically and then tied together to form a steel reinforcement body, which is located inside the concrete panel (2) to form a whole; The side mold (3) is provided with a through hole, and the external thread end of the transverse rib (31) extends into the through hole of the side mold (3); It also includes a threaded sleeve (4) with an internal threaded through hole. The internal threaded through hole of the threaded sleeve (4) is engaged with the external threads at both ends of the transverse rib (31) through the thread pair. The large end of the step of the threaded sleeve (4) stops at the outside of the side mold (3). It also includes a sliding mold (5) that can slide on the side mold (3), the sliding mold (5) being fixedly connected to a steel rope (51), and a winch (52) on the top surface of the rockfill dam (1), with the steel rope (51) wound and connected to the winch (52).
2. The construction structure of a face panel rock-fill dam according to claim 1, characterized in that: A guide support (6) is installed in the middle of the steel rope (51) for guidance and support.
3. The construction structure of a face panel rock-fill dam according to claim 2, characterized in that: The steel rope (51), winch (52), and guide support (6) are in two sets, which are used to connect the two ends of the sliding mold (5).
