Description

A Rock-Socketed Construction Platform for Inclined Pile Groups and Its Erection Method Technical Field

[0001] The present invention relates to a rock-socketed construction platform for inclined pile groups and its erection method. Background Art

[0002] In bridge and wharf structures, multiple pile foundations usually work together, and there are both vertical piles and inclined piles among the multiple pile foundations. Each pile foundation needs to be inserted into the seabed to a certain depth. Due to the complex marine geology, in order to improve the bearing capacity of pile foundations in sea areas with relatively shallow overburden layers, rock-socketed construction of pile foundations is required. When constructing rock-socketed pile foundations, a pile driving vessel is usually used. However, in severe sea conditions and when the pile foundation is close to a steel approach bridge, a traditional pile driving vessel cannot be used, and large equipment such as drilling rigs and crawler cranes need to be used. These rock-socketed construction equipment need to work on an auxiliary platform temporarily erected at sea. To ensure that the construction platform can bear the load during the rock-socketed construction process and provide sufficient working space, the volume of the construction platform is usually large. Therefore, it not only increases the manufacturing difficulty of the construction platform, but also increases the transportation cost and the lifting capacity of the lifting vessel. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a rock-socketed construction platform for inclined pile groups and its erection method, which not only reduces the manufacturing difficulty, but also saves transportation costs, and reduces the lifting capacity of the lifting vessel when the platform is installed at sea.

[0027] Another technical solution to achieve the objective of this invention is: a method for constructing a rock-socketed construction platform for inclined pile groups, used for constructing the rock-socketed construction platform for inclined pile groups of this invention at sea, the method comprising the following steps:

[0028] Step 1: First, insert one corner auxiliary pile into the sleeve of the four corner auxiliary piles on each of the two small platforms, and temporarily fix the two small platforms to the corresponding four corner auxiliary piles. Then, insert one central auxiliary pile into the sleeve of the two central auxiliary piles on each of the two small platforms, and temporarily fix the two small platforms to the corresponding two central auxiliary piles. Finally, load the two small platforms onto the transport ship.

[0029] Step two: First, use the crane ship's hook to connect with the four lifting seats on the first small platform, and lift the first small platform from the transport ship to the work area.

[0030] Step 3: First, hoist the first small platform to the designated position on the water surface and then sink it to the bottom of the seabed. Then, release the temporary fixation between the first small platform and the four corner auxiliary piles, as well as the temporary fixation between the first small platform and the two central auxiliary piles, so that the four corner auxiliary piles and the two central auxiliary piles sink to the seabed by their own weight.

[0031] Step 4: First, use a vibratory hammer to sink one corner auxiliary pile on the first small platform to the set depth on the seabed, and then sink the second and third corner auxiliary piles on the first small platform in sequence.

[0032] Step 5: First, use the crane ship's hook to lift the first small platform to the set height and level it. Then, connect and fix the three corner auxiliary piles, which have been vibrated and sunk to the set depth, to the first small platform through their respective anti-lifting mechanisms.

[0033] Step 6: First, vibrate and sink the fourth corner auxiliary pile on the first small platform to the set depth on the seabed, and then connect and fix the fourth corner auxiliary pile to the first small platform through the corresponding anti-lifting mechanism.

[0034] Step 7: First, vibrate and sink the two central auxiliary piles on the first small platform to the set depth on the seabed, and then connect and fix each central auxiliary pile to the first small platform through several stiffening plates.

[0035] Step 8: First, use the crane ship's hook to connect with the four lifting seats on the second small platform, and lift the second small platform from the transport ship to the working sea area. Then, while connecting the second small platform with the first small platform that has been installed through the guide mechanism and the limiting mechanism, lower the second small platform onto the water surface.

[0036] Step nine, repeat steps three through seven to install the second small platform;

[0037] Step 10: After the second small platform is installed, weld splicing rods between the third-layer platforms of the two small platforms to form an integral rock-embedded construction platform.

[0038] The rock-embedded construction platform for inclined pile groups and its construction method of the present invention have the following characteristics:

[0039] 1. The platform reduces the size and lifting capacity of the gantry crane used in the manufacturing process, making it easier to manufacture and install.

[0040] 2. When transporting the platform, it is possible to select transport vessels with relatively small main dimensions, which solves the problem of difficulty in finding vessels due to the large size of the platform and saves transportation costs.

[0041] 3. When the platform is installed at sea, it can reduce the lifting capacity of the crane vessel; and the use of guiding and limiting mechanisms facilitates the alignment of the two small platforms during installation, solving the problem of difficult alignment during the installation of the two small platforms.

A method for constructing a rock-socketed construction platform for inclined pile groups, used for constructing a rock-socketed construction platform for inclined pile groups as described in claim 1 at sea, the method comprising the following steps: Step 1: First, insert one corner auxiliary pile into the sleeve of the four corner auxiliary piles on each of the two small platforms, and temporarily fix the two small platforms to the corresponding four corner auxiliary piles. Then, insert one central auxiliary pile into the sleeve of the two central auxiliary piles on each of the two small platforms, and temporarily fix the two small platforms to the corresponding two central auxiliary piles. Finally, load the two small platforms onto the transport ship. Step two: First, use the crane ship's hook to connect with the four lifting seats on the first small platform, and lift the first small platform from the transport ship to the work area. Step 3: First, hoist the first small platform to the designated position on the water surface and then sink it to the bottom of the seabed. Then, release the temporary fixation between the first small platform and the four corner auxiliary piles, as well as the temporary fixation between the first small platform and the two central auxiliary piles, so that the four corner auxiliary piles and the two central auxiliary piles sink to the seabed by their own weight. Step 4: First, use a vibratory hammer to sink one corner auxiliary pile on the first small platform to the set depth on the seabed, and then sink the second and third corner auxiliary piles on the first small platform in sequence. Step 5: First, use the crane ship's hook to lift the first small platform to the set height and level it. Then, connect and fix the three corner auxiliary piles, which have been vibrated and sunk to the set depth, to the first small platform through their respective anti-lifting mechanisms. Step 6: First, vibrate and sink the fourth corner auxiliary pile on the first small platform to the set depth on the seabed, and then connect and fix the fourth corner auxiliary pile to the first small platform through the corresponding anti-lifting mechanism. Step 7: First, vibrate and sink the two central auxiliary piles on the first small platform to the set depth on the seabed, and then connect and fix each central auxiliary pile to the first small platform through several stiffening plates. Step 8: First, use the crane ship's hook to connect with the four lifting seats on the second small platform, and lift the second small platform from the transport ship to the working sea area. Then, while connecting the second small platform with the first small platform that has been installed through the guide mechanism and the limiting mechanism, lower the second small platform onto the water surface. Step nine, repeat steps three through seven to install the second small platform; Step 10: After the second small platform is installed, weld splicing rods between the third-layer platforms of the two small platforms to form an integral rock-embedded construction platform.
