High pier capable of reducing hydration heat of mass concrete and construction method thereof
The invention relates to the technical field of bridge engineering, and particularly discloses a high pier capable of reducing hydration heat of mass concrete and a construction method thereof. The high pier comprises a vertical steel reinforcement framework, a plurality of horizontal steel reinforcement layers and a cooling unit. The cooling unit comprises a connecting device, a plurality of horizontal cooling layers, a vertical water passing pipe and a partition plate, and each horizontal cooling layer comprises a threaded steel pipe; a plurality of groups of communicating nodes are vertically arranged on the vertical water passing pipe, each communicating node comprises a water inlet and a water outlet, the water inlet is located below the water outlet, and the water inlet and the wateroutlet are connected with the two ends of the threaded steel pipe respectively; and a plurality of limiting rods are vertically and fixedly arranged in the vertical water passing pipe, limiting holesare formed in the partition plate, the limiting rods are in sliding sealing contact with the limiting holes, the partition plate is in sliding sealing contact with the inner wall of the vertical water passing pipe, a curved-surface-shaped vertical plate is vertically arranged on the partition plate, a plurality of first fixing holes are formed in the vertical plate, and a water flowing hole is arranged in the bottom of the vertical plate. The method aims to solve a problem that heat in concrete is gathered and cannot be dissipated.
本发明涉及桥梁工程技术领域，具体公开了可降低大体积混凝土水化热的高墩及其施工方法，包括竖向钢筋骨架、若干水平钢筋层以及冷却单元，冷却单元包括连接装置、若干水平冷却层、竖向通水管和隔板，水平冷却层包括螺纹钢管；竖向通水管上竖直设有若干组联通节点，联通节点包括入水口和出水口，入水口位于出水口的下方，入水口和出水口分别与螺纹钢管的两端联通；竖向通水管内竖直固定设有若干限位杆，隔板上设有限位孔，限位杆与限位孔滑动密封接触，隔板与竖向通水管的内壁滑动密封接触，隔板上竖直设有曲面形的竖直板，竖直板上设有若干第一固定孔，竖直板的底部设有流水孔。本发明意在解决混凝土内部热量聚集而无法散出的问题。
