摘要:
针对三河闸因防洪标准提高导致抗滑稳定安全富余下降、底板局部钢筋受损等问题，比选多种技术方案，推荐采用锚杆技术加固改造。锚杆布置避开钢筋密集区，并选在底板跨中部位，以确保不切断受力钢筋，并改善闸底板受力。在三孔一连的闸底板上，闸孔内各布置1组，门墩之间各布置1组，共8组。每组锚杆选用数根常用钢绞线，锚碇设在地基偏上游方向，锚杆角度设为45°左右，锚杆张力不超过其破断力的75%。结合锚杆锚具的设置，将闸底板一定范围用钢筋混凝土填平，进一步补强底板。该加固方案使工程在各种工况下均满足抗滑稳定要求，无需构筑挡洪围堰，无需导流，工期较短，投资节省。
Abstract:
In view of the problems such as the decline of safety surplus of anti-sliding stability and the damage of local steel reinforcement in the bottom plate of Sanhe Sluice due to the improvement of flood control standards, a variety of technical schemes are compared and the anchor technology is recommended for reinforcement. The anchor bolt is arranged to avoid the densely reinforced area, and is selected in the middle of the floor span to ensure that the stressed reinforcement is not cut off, and to improve the force of the gate floor. On the base plate of the gate with three consecutive holes, a group is arranged in each hole and a group is arranged between the door piers, a total of 8 groups. Several common steel strands are selected for each group of anchor bolts. The anchoring is set in the upstream direction of the foundation, the angle of the ancho bolts is set at about 45°, and the tension of the bolts does not exceed 75% of its breaking force. Combined with the setting of anchor bolts, the bottom plate of the gate is filled with reinforced concrete in a certain range to further strengthen the bottom plate. The reinforcement scheme makes the project to meet the requirements of anti-sliding stability under various working conditions, without the construction of flood retaining cofferdam, no diversion, short construction period and small investment.
