Example 1

As shown in fig. 1 and 2, the high pile cap foundation installation system for the present embodiment includes: the shallow draft barge 1 is arranged in a foundation area of a high pile cap to be constructed; a transport vessel 2 adapted to transport material to the shallow draft barge 1; the hoisting device 3 is arranged on the shallow draft barge 1; and a pile embracing frame 4 for positioning the pile sinking position.

The shallow draft barge 1 in this embodiment is a bottom-mountable double-deck barge, which is abundant and easy to find.

As shown in fig. 1, the shallow draft barge 1 in the present embodiment is an unpowered vessel, and when construction starts, the shallow draft barge is pulled to the area of the high pile cap foundation to be constructed by using a transport vessel or other power vessels (such as a jettison vessel) and the like, and the shallow draft barge 1 is fixed by using anchor cables 7, so as to provide a good construction platform for the next construction.

After the shallow draft barge 1 is secured, the carrier 2 can transport the lifting devices 3 to the shallow draft barge 1 and effect assembly on the shallow draft barge 1.

In other embodiments, the hoisting device 3 may be assembled on the shallow draft barge 1 in advance, and dragged along with the shallow draft barge 1 into the foundation area of the high pile cap to be constructed.

The hoisting device 3 in the embodiment is a crawler crane which can move freely, and the high-pile sinking platform foundation material can be hoisted conveniently. In the embodiment, two crawler cranes are arranged on the shallow draft barge 1, and the two crawler cranes have different models, one is large and the other is small. When the steel pile 6 is transported in the transport ship 2, the steel pile 6 transversely placed on the transport ship needs to be lifted to be in a vertical state, two crawler cranes respectively lift two ends of the steel pile 6, the lifting heights are different due to different sizes of the crawler cranes, the steel pile 6 is easily lifted to be in a vertical state, and subsequent pile sinking work is facilitated.

Of course, in other embodiments, the number of the crawler cranes can be three, four, etc., so as to improve the efficiency of lifting the materials.

Of course, in other embodiments, the hoisting device may also be a tower crane, a gantry crane, or the like.

To facilitate the lifting of the steel piles 6 from the carrier vessel 2, crawler cranes are mounted close to the side of the shallow draft barge 1.

The shallow draft barge 1 is adopted to replace a traditional piling barge, so that a corresponding pile embracing structure is lacked to realize the positioning piling of the steel pile 6, and the pile embracing frame 4 is provided in the embodiment. The pile embracing frame 4 is provided with a plurality of guide cylinders, wherein the number of the guide cylinders is determined according to the number of the steel piles 6 required in the pile sinking process. Under the hoisting action of the crawler crane, the steel piles 6 are inserted into the guide cylinders, so that the implementation positions of the steel piles 6 are preliminarily positioned.

The pile embracing frame 4 in this embodiment needs to position the steel pile 6, so it needs to be fixed in the area of the foundation of the high pile cap. In order to fix the pile embracing frame 4, the bottom of the pile embracing frame 4 in the embodiment is of a suction barrel structure, and a pump prying block system is arranged on the suction barrel. In the process that the pile embracing frame 4 sinks into the seabed, the suction barrel is filled with water, the water in the suction barrel is continuously sucked out through the pump prying block system, and the suction barrel is gradually pressed into a mud layer on the seabed under the action of the external seawater pressure and the atmospheric pressure, so that the pile embracing frame 4 is fixed. When the quantity of suction bucket is a plurality of, through what more easily control the submerged distance between different suction buckets of suction water yield, conveniently guarantee the levelness of whole embracing pile frame 4.

Of course, in other embodiments, the pile embracing frame 4 may also be driven by pile sinking with a heavy object at the bottom.

After the steel pile 6 is inserted into the guide cylinder in the pile embracing frame 4 under the action of the crawler crane, preliminary fixing is realized under the action of the pile embracing frame 4. And then the crawler crane lifts the hydraulic hammer 5, the upper end of the steel pile 6 is beaten, and the steel pile 6 is wedged into the seabed mud layer to realize final fixation.

After the steel piles 6 are fixed, subsequent rock-socketed construction is carried out. Before the rock-socketed construction is carried out, water is injected into the suction barrel of the pile embracing frame 4 and ejected out, the pile embracing frame 4 is hoisted back to the shallow draft barge 1, and then the rock-socketed platform is installed for the rock-socketed construction. Because the construction period of the rock-socketed construction is longer, the rock-socketed construction does not use shallow draft to participate. After the shallow draft barge finishes pile sinking operation, the shallow draft barge can go to the next machine position for construction, and the construction efficiency is improved.

And (4) carrying out bearing platform construction after rock-socketed construction, wherein the construction mainly comprises the steps of binding of steel bars in the traditional bearing platform, installation of a foundation ring, concrete pouring and the like.

Therefore, in the embodiment, the shallow draft barge is adopted to replace the traditional pile driving barge, and pile sinking can be directly constructed on the shallow draft barge by utilizing the pile embracing frame, so that the high pile cap foundation is installed. The shallow draft barge in the embodiment is mostly provided with double-layer bottoms, so that the operation safety is improved, the resources are easy to find, the price is low, and the construction cost of the high pile cap foundation is reduced. And the shallow draft barge has shallow draft, can enter a part of ultra-shallow water area when being wet, has wide construction range, and simultaneously ensures that part of offshore wind power shallow water machine positions which cannot be constructed have construction conditions.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
