Steel sheet pile cofferdam suitable for deep and thick silt layer and construction method
The invention provides a steel sheet pile cofferdam suitable for a deep and thick silt layer. The steel sheet pile cofferdam comprises steel sheet piles, surrounding purlins, pull rods, supporting rods, a grating net, a steel pipe net and filling materials. The steel sheet piles are arranged in two layers in parallel, the lower ends of the steel sheet piles extend into the foundation, and the inner side and the outer side of each layer of steel sheet piles are provided with an upper surrounding purlin and a lower surrounding purlin. The pull rod is arranged between the two layers of steel sheet piles which are arranged in parallel; the lower ends of the supporting rods are fixed to the steel pipe net, and the upper ends of the supporting rods are fixed to the upper surrounding purlin. The steel pipe nets are arranged on the inner sides and the outer sides of the steel sheet piles. The grating net is laid on the upper portion of the steel pipe net, and filling materials are arranged above the grating net. The filling and the steel sheet piles are tightly combined together through the enclosing purlins, the supporting rods, the steel pipe net and the grating net, the integrity of the steel sheet pile cofferdam is enhanced, the foundation area of the steel sheet pile cofferdam and a bottom sludge layer is larger, concentrated loads are converted into evenly distributed loads, and the problems of subsidence, slippage and uneven settlement in the prior art can be effectively solved.
本发明提供一种适用于深厚淤泥层的钢板桩围堰，包括钢板桩、围檩、拉杆、支撑杆、格栅网、钢管网以及填筑物；所述钢板桩呈两层平行布置，所述钢板桩的下端伸入至基础内，每层钢板桩的内侧和外侧设有上部围檩和下部围檩；所述拉杆设置在平行布置的两层钢板桩之间；所述支撑杆的下端固定至钢管网上，所述支撑杆的上端固定至上部围檩上；所述钢管网设置在钢板桩的内侧和外侧；所述格栅网铺设在钢管网上部，所述格栅网上方设置填筑物。本发明通过围檩、支撑杆、钢管网、格栅网将填筑物与钢板桩紧密组合在一起，增强钢板桩围堰的整体性，与底部淤泥层的基础面积更大，将集中荷载转化为均布荷载，可以有效解决现有技术沉陷、滑移与不均匀沉降的问题。
