Description
Technical Field
The invention relates to a floating and sinking assisting device and method for a base barrel body of a barrel type breakwater.
Background
The traditional slope type breakwater structure increases the structural section along with the increase of the water depth, so that the engineering quantity is huge, more stone materials are needed, and the defects of long construction period, wind wave influence in the construction period, high construction cost and the like exist. Therefore, through comparison of multiple schemes, a vertical breakwater structure taking a barrel structure as a unit is developed and developed. The base tub body of such a tub breakwater is generally composed of a lower tub body and a plurality of upper tub bodies. The lower barrel body and the upper barrel body are both prefabricated by reinforced concrete. The lower barrel body is an inverted large-diameter barrel with an opening at the bottom end and a closed top end, and is provided with a plurality of compartments. The foundation barrel body has the characteristics of being prefabricated in an industrial mode, needing no foundation reinforcement, being high in field installation speed, outstanding in technical economy and the like, and is particularly suitable for the breakwater constructed on the soft soil foundation.
When the base barrel body is installed, the base barrel body is partially inserted into the soil by means of the dead weight of the base barrel body to form a closed space, then the gas of each compartment in the lower barrel body is extracted to keep the base barrel body stable, and the lower barrel body is gradually pressed into the seabed to a preset depth by means of the internal and external pressure difference to complete installation.
Under the deepwater condition, when the air valve of the lower barrel body is opened, the basic barrel body sinks into the water slowly, and the air in the lower barrel body is reduced gradually. When the lower barrel body is completely sunk into water and is not contacted with a mud surface, the gas buoyancy moment generated by the base barrel body is smaller, the base barrel body is in an unstable balance state under the action of waves and water flow and the action of the tilting moment generated by the gravity of the base barrel body, and the base barrel body cannot be kept to sink continuously at a stable position by adjusting the air pressure of each compartment of the lower barrel body, so that safety accidents are easily caused.
