Tidal influence type steel sheet pile island-building cofferdam and construction method
The invention relates to a tide influence steel sheet pile island building cofferdam and a construction method. The construction method comprises the steps that high-pressure jet grouting piles are constructed; inserting and driving steel pipe piles, erecting a temporary steel bridge and erecting a guide frame; connecting a steel sheet pile inserting and driving module; adjustable supporting frames are installed below the steel beams, and cofferdam filling modules are connected; a sand filling cofferdam is built in the muddy soil layer; wave-proof building blocks are arranged on the water-facing side of the sand-filled cofferdam; and backfilling the backfilled soil until the designed elevation is reached. The cofferdam has the beneficial effects that the two rows of Larsen steel sheet piles are arranged on the near-water side of the cofferdam body, the adjustable supporting frames and the high-pressure jet grouting piles are arranged between the two rows of Larsen steel sheet piles, and the stability and safety of the near-water side of the cofferdam are greatly improved; the adjustable supporting frame is adopted, the height of the vertical rod is adjusted to control the position of the horizontal support, the deformation and stress conditions of the Larsen steel sheet pile at the position where the horizontal support is located can be measured in real time through the axial force sensor and the displacement sensor on the horizontal support, and deformation and stress of the Larsen steel sheet pile are effectively controlled.
本发明涉及一种潮汐影响钢板桩筑岛围堰及施工方法，包括步骤：施作高压旋喷桩；插打钢管桩，搭设钢便桥并架设导向架；连接钢板桩插打模块；在钢梁下安装可调式撑架并连接围堰填筑模块；在淤泥质土层中搭建充砂围堰；在充砂围堰临水侧安设防波砌块；并回填回填土直至设计标高。本发明的有益效果是：围堰主体临水侧设置两排拉森钢板桩的结构形式，在两排拉森钢板桩之间设置可调式撑架和高压旋喷桩，大大提高了围堰临水侧的稳定性和安全性；采用可调式撑架，调整竖杆的高度来控制水平支撑的位置，通过水平支撑上的轴力传感器和位移传感器可实时测量其所在位置处拉森钢板桩的变形和受力情况，有效控制拉森钢板桩的变形和受力。
