Ecological steel sheet pile island construction cofferdam and construction method
The invention provides an ecological steel sheet pile island construction cofferdam and a construction method. An in-situ solidification layer, a clay filling layer and greening planting soil are arranged between a first steel sheet pile and a second steel sheet pile; a position control tie bar and a riprap back pressure body are arranged on the side, facing a water body, of a third steel sheet pile, and the stability of the position control tie bar can be improved through an anti-pulling anchor bar and an anti-pulling grouting body; a top supporting beam is arranged at the top ends of the first steel sheet pile and the second steel sheet pile, a sliding supporting column capable of moving in the longitudinal direction of the top supporting beam is arranged, and a pressure control body isadopted for applying compaction pressure to the clay filling layer; pile top crown beams are arranged at the top ends of the first steel sheet pile and the third steel sheet pile, a wave-proof pressing plate is arranged at the bottom end of a connecting sleeve, and an oil blocking rope is arranged at the bottom end of the oil blocking rope lifting rope; and a heightened baffle is arranged on the upper part of the pile top crown beam. The stress performance and the greening effect of the cofferdam can be improved, the field construction efficiency is improved, and the construction environment is protected.
本发明提供一种生态钢板桩筑岛围堰及施工方法，在第一钢板桩与第二钢板桩之间设置了原位固化层、粘土填筑层和绿化种植土；在第三钢板桩面向水体侧设置了控位拉筋和抛石反压体，并可通过抗拔锚筋和抗拔注浆体提升控位拉筋的稳定性；在第一钢板桩和第二钢板桩的顶端设置了顶部撑梁，并设置了可沿顶部撑梁纵向移动的滑移撑柱，采用压力控制体对粘土填筑层施加密实压力；在第一钢板桩和第三钢板桩的顶端设置了桩顶冠梁，并在连接套管底端设置了防浪压板，在拦油绳吊绳的底端设置了拦油绳索；在桩顶冠梁的上部设置了加高挡板。本发明可改善围堰的的受力性能和绿化效果、提高现场施工效率、保护施工环境。
