Description

Technical Field

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

[0002] In bridge and wharf structures, multiple pile foundations usually work together, and there are both vertical piles and batter piles among them. 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 conducting rock - socketed construction of 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, the traditional pile driving vessel cannot be used, and large - scale 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 built at sea. To ensure that the construction platform can bear the loads 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.

8. A method for constructing a rock-embedded construction platform of an inclined pile group, used for constructing the rock-embedded construction platform of an inclined pile group as claimed in claim 1 at sea, the method comprising the following steps: Step 1: First, insert one corner auxiliary pile into each of the four corner auxiliary pile sleeves on the two small platforms, and temporarily fix the two small platforms to the corresponding four corner auxiliary piles; insert one middle auxiliary pile into each of the two middle auxiliary pile sleeves on the two small platforms, and temporarily fix the two small platforms to the corresponding two middle auxiliary piles; then load the two small platforms onto the transport ship respectively; Step 2: First, use the hook of the crane ship to connect with the four lifting seats on the first small platform, and lift the first small platform from the transport ship to the operating sea area; Step 3: First, hoist the first small platform to the designated position on the water surface and then sink it to the seabed, then release the temporary fixation between the first small platform and the four corner auxiliary piles and the temporary fixation between the first small platform and the two middle auxiliary piles, so that the four corner auxiliary piles and the two middle auxiliary piles sink to the seabed by their own weight; Step 4: First, use a vibrating hammer to vibrate and sink a corner auxiliary pile on the first small platform to a set depth on the seabed, and then vibrate and sink the second corner auxiliary pile and the third corner auxiliary pile on the first small platform in sequence; Step 5: First, use the hook of the crane ship to lift the first small platform to the set height and level it, and then connect and fix the three corner auxiliary piles that have been vibrated to the set depth to the first small platform through the corresponding anti-lifting mechanism; 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 reverse hanging mechanism; Step 7: First, vibrate and sink the two middle auxiliary piles on the first small platform to the set depth on the seabed, and connect and fix each middle auxiliary pile to the first small platform through a number of rib plates; Step 8: First, use the hook of the crane ship to connect with the four lifting seats on the second small platform, lift the second small platform from the transport ship to the operating sea area, and then dock the second small platform with the installed first small platform through the guide mechanism and the limit mechanism, and lower the second small platform to the water surface; Step 9, repeat steps 3 to 7 to install the second small platform; Step 10. After the second small platform is installed, the connecting rods are welded between the third-layer platforms of the two small platforms to form an integral rock-embedded construction platform.
