Construction method for dismantling offshore anemometer tower
The invention relates to an offshore anemometer tower dismantling construction method which comprises three steel pipe concrete piles, the lower ends of the three steel pipe concrete piles are embedded below a silt layer, six connecting steel pipes in two layers are horizontally arranged on the upper portions of the three steel pipe concrete piles, and a concrete bearing platform is arranged at the upper ends of the three steel pipe concrete piles. Berthing and anti-collision section steel is arranged on the peripheral side of the concrete bearing platform, a steel crawling ladder extending downwards is arranged on one side of the concrete bearing platform, and an anemometer tower body and a bearing platform handrail are arranged on the platform face of the concrete bearing platform. The method comprises the following steps that the anemometer tower body is dismantled, specifically, an anemometer instrument and an anemometer tower frame are dismantled; a bearing platform handrail, a steel crawling ladder, a berthing ship and anti-collision profile steel are dismantled; drilling holes in two layers on the concrete bearing platform, filling the holes with a silent expanding agent, chiseling away the silent expanding agent by using an air compressor, and grabbing slag by using a grab dredger; dredging a foundation trench 3m below the mud surface of the three steel pipe concrete piles, and performing underwater cutting on the steel pipe concrete piles; and the three steel pipe concrete piles and the six connecting steel pipes are integrally hoisted and dismantled. According to the method, the decommissioned offshore anemometer tower structure can be demounted easily, the marine ecological environment is protected, limited sea area resources are saved, and the economic pressure of enterprises is reduced.
本发明涉及一种海上测风塔拆除施工方法，海上测风塔包括三根下端埋入淤泥层以下的3根钢管砼桩，位于3根钢管砼桩的上部水平设置有两层共6根连接钢管，位于3根钢管砼桩的上端设置有混凝土承台，混凝土承台周侧设置有靠船及防撞型钢，且其中一侧设置有向下延伸的钢爬梯，混凝土承台的台面上设置有测风塔塔体及承台栏杆，包括以下步骤：测风塔塔体拆除：拆除测风仪器和测风塔架；拆除承台栏杆、钢爬梯、靠船及防撞型钢；在混凝土承台上分两层钻孔，在钻孔内填塞无声膨胀剂，并用空压机凿除，抓斗挖泥船抓渣；在3根钢管砼桩泥面以下3m基槽挖泥，进行钢管砼桩水下切割；将3根钢管砼桩、6根连接钢管整体吊装拆除。该方法有助于拆除退役的海上测风塔结构，保护海洋生态环境，节约有限的海域资源、削减企业的经济压力。
