Pressure regulating method of channel repair cofferdam base water bag load transfer structure
The invention discloses a pressure regulating method for a channel repair cofferdam base water bag load transfer structure, which comprises the following steps: dividing the bottom of a cofferdam into a plurality of pressure areas, calculating a preset pressure value of each pressure area by combining the self weight of the cofferdam, water load and the like, arranging a set of sealed water bag load transfer structure in each pressure area, and pressing water into a water bag by adopting a booster pump, water pressure is controlled through a water pressure sensor, the flexible rubber bottom plate at the bottom of the water bag makes contact with the lining plate, and when the thickness of the water bag is larger than the unevenness of the concrete surface, the flexible rubber bottom plate deforms to adapt to the convex-concave surface of the concrete under the action of internal equal water pressure; the pressure intensity of the outer surface of the flexible rubber bottom plate is equal, and the load transmitted to the outer surface of the concrete by the water bag is uniform surface load. According to the method, the local pressure intensity of the cofferdam base can be prevented from exceeding the bearing capacity of the channel foundation, the safety of an original structure is ensured when the cofferdam is adopted for repairing the channel lining plate, and great economic value is achieved.
本发明公开了一种渠道修复围堰基座水囊荷载传递结构的调压方法，通过将围堰底部分为若干压力区，结合围堰自重、水荷载等计算出各压力区的预设压力值，在每个压力区设置一套密封水囊荷载传递结构，采用增压泵将水压入水囊，通过水压传感器控制水压，使水囊底部的柔性橡皮底板与衬砌板接触，当水囊厚度大于混凝土表面不平整度时，柔性橡皮底板在内部等水受压的作用下发生适应混凝土表面凸凹的变形，因水囊内部水压相等，柔性橡皮底板的外表面压强相等，水囊传递到混凝土外表面的荷载就是均匀的面荷载。本发明能够避免围堰基座局部压强超过渠道地基的承载能力，确保采用围堰修复渠道衬砌板时原构筑物的安全，具有较大的经济价值。
