The periphery of the passive hammer 202 is an arc surface protruding outwards; as shown in fig. 1, passive hammer 202 has a drum-shaped structure as a whole, and has a first hollow structure 203 inside.
The upper surface of the passive hammer 202 is provided with a plurality of groups of hooks along the edge thereof, and the hooks are hung with chains 1010 to be connected with the sealing cover 1.

In a preferred embodiment of the environment-friendly sealed underwater dynamic compaction system, the sealing cover 1 is formed by connecting at least two cylinders in series, and the series part adopts a flexible connection structure, and can be a clamp type flexible joint or a rubber flexible joint; the main reason is that when the driving hammer 201 strikes the driven hammer 202, huge vibration is generated, and if the sealing cover 1 is integrated, the upper part can also strongly vibrate, so that a structure with upper and lower series connection and flexible connection is formed. In the embodiment, the sealing cover 1 is composed of two cylinders connected in series, the inner diameter of the upper cylinder 101 is slightly larger than the diameter of the driving hammer 201, the inner diameter of the lower cylinder 102 is slightly larger than the diameter of the driven hammer 202, and the diameter of the lower cylinder 102 is also larger than the diameter of the lower cylinder 102 because the diameter of the driven hammer 202 is larger than the diameter of the driving hammer 201.
Reinforcing ribs which are arranged at intervals along the circumferential direction and the vertical direction are arranged on the outer surface of the sealing cover 1. The sealing cover 1 is ensured to have enough strength and is prevented from deforming under the action of water pressure.
The use method of the environment-friendly sealed underwater dynamic compaction system has the following advantages:
when in use, the system is lifted to a specified position by a crane ship. The passive hammer 202 is placed on the top surface of the foundation bed and the chain 1010 is released. Because the weight of the passive hammer 202 and the sealing cover 1 is slightly larger than the buoyancy of water, the sealing cover 1 can be placed under water in a correct posture without floating, and meanwhile, the sealing cover 1 can bear the pressure under water without deformation due to the reinforcing ribs.
The winch 104 is started, the driving hammer 201 is hoisted, the driving hammer 201 continuously rises, the driving hook is in contact with the unhooking separation blade 106, the hook blade is extruded by the unhooking separation blade 106, the upper portion inwards converges, the lower portion is separated towards the periphery, the driving hook is separated from the driven hook 2010, the driving hammer 201 falls down along the positioning rod, finally collides with the driven hammer 202, energy is transmitted to the driven hammer 202, and then the base bed is tamped.
The main hammer 201 is restrained by the locating rod in the falling process, so that the hemisphere can accurately impact the center of the concave surface at the top of the passive hammer 202, and the passive hammer 202 is enabled to be evenly stressed stably. Meanwhile, the air in the sealing cover 1 flows from below the driving hammer 201 to above the driving hammer 201 through the vent hole 206.
When the passive hammer 202 is hit by the active hammer 201, a large shock is generated and a certain sinking and shifting occurs. The flexible connection structure of the positioning rod hinge ring and the upper rod 1012 can greatly reduce the influence of the vibration of the driving hammer 201 on the sealing cover 1, and the flexible chain 1010 can also greatly reduce the influence of the vibration of the driven hammer 202 on the sealing cover 1. The flexible chain 1010 allows it to sink and deflect without pulling on the closure 1, and the provision of a three-layer seal ensures the leak tightness of the overall system in this case. The safety of the sealing cap 1 is ensured by multiple safeguards.
Subsequently, since the hoist 104 is set to the stroke, the fall of the hoist rope 2016 is continued after the active hook is disengaged from the passive hook 2010, and the active hook comes into contact with the passive hook 2010 again. The hook piece touches the cone, the lower part of the cone is opened until the hook piece falls to the bottom surface of the cone, and the hook piece is inwardly gathered under the influence of gravity to complete the hook action. The hoist 104 then lifts the hammer 201 upward, and so on.
In order to reduce the pressure difference between the inside and the outside of the airtight enclosure 1 and ensure the safety of the inside of the system in the working process, air needs to be pumped into the air nozzle 103 continuously.
The system is convenient to use and reliable in structure, the driving hammer 201 is arranged in the air in the whole falling process, the underwater construction is performed on the land, the problem that energy loss of the rammer in the falling process of the traditional underwater dynamic compaction process is serious in the process of underwater falling is solved ingeniously, and the ramming efficiency and the ramming quality are improved greatly. In addition, due to the double-hammer design of the driving hammer 201 and the driven hammer 202, the vibration position during tamping is generated inside the sealing cover 1, the influence of vibration on the surrounding environment is basically eliminated through double attenuation of the air layer and the sealing cover 1, the damage of underwater strong construction vibration on the living environment of surrounding aquatic organisms is thoroughly avoided, and the high popularization value is achieved.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable to various fields of endeavor for which the invention may be embodied with additional modifications as would be readily apparent to those skilled in the art, and the invention is therefore not limited to the details given herein and to the embodiments shown and described without departing from the generic concept as defined by the claims and their equivalents.
