Abstract
The invention provides an anti-tilting and anti-sinking floating body frame. The floating body frame is in a detachable combined framework structure and comprises at least three PVC (polyvinyl chloride) pipes which are in head-to-tail connection, the pipes are hollow pipes, lightweight solid filling materials with the density of less than water density are arranged in pipe cavities, the length of the filling material in the single pipe is not longer than the length of the single pipe, and the outer diameter of the filling materials is not more than the inner diameter of the pipes. By increasing the buoyancy enhancement filling materials in the floating body frame constituted by the PVC pipes, the newly added cost is low in construction, and the problem that the maintenance cost is increased due to tilting or sinking after water enters the well assembled framework system or water enters the floating body frame due to various reasons is well solved. Even if the connection part of the floating body frame has water leakage or the PVC pipes are ruptured to cause the water leakage, as most of the cavities in the pipes are occupied by the buoyancy enhancement filling materials, the water incoming amount is very limited, the water in the pipes can flow freely, and the sinking and tilting phenomena can be further avoided.
