Abstract

The invention discloses a slinging method. An opposite corner slinging method is mainly used. The method includes the steps that firstly, according to the water flow direction, two incident flow corners of a platform are acquired through detection; the two incident flow corners of the platform are slung; the other two corners of the platform are slung, sand pockets in the four corners of the platform are respectively of a pile shape, and therefore the platform is stabilized; finally other positions of the platform are slung. The method has the advantages that economical efficiency and high efficiency are achieved, pollution is avoided, and operability is high, and construction requirements can be met. Sand piles formed after slinging are connected tightly and are not prone to being undermined, anti-scouring protection can be provided for the base type platform, and the base type platform can be well protected.
本发明公开了一种抛砂方法,主要使用了‘对角抛砂法’,首先根据水流的方向,检测获得平台迎流的两个角;然后对平台迎流的两个角进行抛砂;再对平台的另外两个角进行抛砂,以使平台四角的砂袋呈堆状,以稳定平台;最后对平台的其它位置进行抛砂。该方法具有经济、高效、无污染、操作性强等特点,能够满足施工要求。抛砂后形成的砂堆连接紧密,不易被淘空,能够为保护座底式平台提供防冲刷保护,并且很好地保护座底式平台。
