Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a synchronous riprap ramming vessel, which is provided with a first rail 1 and a second rail 2 on the port and starboard side of a main deck, respectively, where the first rail 1 and the second rail 2 extend in a hull direction and are parallel to each other; two chute trolleys 3 are arranged on the first track 1, and a tamping platform trolley 4 is arranged on the second track 2. The elephant trunk trolley 3 and the tamping platform trolley 4 are respectively driven by a plurality of winches 6, and can independently move and operate on respective tracks. Specifically, two ends of the first track 1 are respectively provided with 2 winches, and two elephant trunk trolleys 3 are controlled to walk on the first track 1 through steel cables; two ends of the second track 2 are respectively provided with 1 winch, and the tamping platform car 4 is controlled to travel on the second track 2 through a steel cable; in addition, four winches are arranged on the elephant trunk trolley 3 to control the elephant trunk to stretch, and two winches are arranged on the tamping platform trolley to control the vibration hammer to lift.

In the embodiment, the chute stone throwing system and the vibration tamping system of the synchronous stone throwing tamping vessel are respectively arranged on the left side and the right side of the vessel, have respective trolley running tracks and are controlled by different winches to move and work, the construction is not interfered with each other, and the synchronous stone throwing tamping vessel has the condition of simultaneous operation. And only carrying out stone throwing operation on the vessel position before entering each time, and after the vibration tamping system of the subsequent vessel position enters a preset construction area, simultaneously carrying out stone throwing and vibration tamping operation, thereby greatly improving the construction efficiency.

Specifically, 2 stands of 1.5m are used³The excavator with bucket capacity is matched with two sets of riprap elephant trunks for construction, and the construction efficiency is 1800m³D, the single immersed tube riprap amount is 15209m³(average), the required time was 9 days; the ramming area of a single immersed tube foundation is 8580m²And the time for completing the ramming construction of the single immersed tube foundation is 3 days. The construction of the synchronous stone throwing and tamping ship is adopted, the stone throwing and tamping construction is carried out synchronously, the tamping time of 3 days can be saved, and the construction efficiency is improved.
