Self-travelling type island-reef foundation construction platform

Abstract

The invention discloses a self-travelling type island-reef foundation construction platform which comprises a platform main body; at least one travelling mechanism is arranged on the platform main body; the travelling mechanism drives the platform main body to act; at least one side of the platform main body is equipped with a construction opening which penetrates into the platform main body by certain distance; and the size of the construction opening is matched with the size of a to-be-positioned construction part. The invention discloses the self-travelling type island-reef foundation construction platform which is simple to operate, is stable and reliable, guarantees pile forming quality, ensures quick and precise platform positioning and greatly saves construction time.

Description

technical field [0001] The invention relates to a self-propelled island and reef foundation construction platform. Background technique [0002] The key to building permanent buildings on ocean coral reefs is how to efficiently and reliably complete the construction of foundations and how to reduce damage to nature while ensuring high efficiency. Now, the expansion of reefs and islands is built by blowing sand and filling reefs. The way of the island, but this way has greatly damaged the coral reef plate, causing irrecoverable losses to the coral reef plate. Moreover, the reef islands formed in this way are simply land filled with coral reefs and sand, and are easily destroyed when they encounter waves and sea wind erosion. Therefore, it is necessary to build cofferdams around the reclamation area to prevent wave erosion, and An isolation layer composed of concrete and sand is required on the cofferdam to block the contact between sandbags and seawater.

[0002] The key to building permanent buildings on ocean coral reefs is how to efficiently and reliably complete the construction of foundations and how to reduce damage to nature while ensuring high efficiency. Now, the expansion of reefs and islands is built by blowing sand and filling reefs. Island way, but this method has greatly damaged the coral reef plate, causing irreparable damage to the coral reef plate

Moreover, the reef islands formed in this way are simply land filled with coral reefs and sand, and are easily destroyed when they encounter waves and sea wind erosion. Therefore, it is necessary to build cofferdams around the reclamation area to prevent wave erosion, and An isolation layer composed of concrete and sand is required on the cofferdam to block the contact between sandbags and seawater. At the same time, concrete parts need to be arranged on the outermost periphery to block waves. Therefore, islands built in this way require a lot of sand to Filling is not only costly, time-consuming and labor-intensive, but also brings immeasurable losses to the ecology. Therefore, making high pile caps is undoubtedly a good solution to solve the underwater reef foundation and the protruding sea platform at the same time.

[0003] Currently, construction platforms on islands and reefs use pile drivers to drive piles on coral reefs first and then lay piles. However, because pile drivers need to be positioned during construction, the existing construction platforms use "two-petal machine-tied boats" The positioning hole is set between the two-petal-shaped machine-tied boats. After the pile is completed, the pile is above the water surface and the pile is just at the junction of the two petals. The hull must be separated to move to the next pile position. However, the existing construction The platform is non-self-propelled, and the displacement needs to be dragged or pushed by a large ship. This displacement method is time-consuming and troublesome to operate. In addition, the existing construction platform is floating on the water when it is working, and the stability of the platform depends on the outriggers. Pressed through the platform to the bottom of the sea

Since the outriggers are not fixed on the platform, they can slide up and down in the platform. The tide of sea water will cause the construction platform to float up and down. If the waves are large, it may also push the platform to move laterally, which will have a certain impact on the quality of the pile.
