Self-walking type island foundation construction platform with drilling and hoisting device

Abstract

A self-walking type island foundation construction platform with a drilling and hoisting device comprises a platform body and a drilling and hoisting integrated drilling machine. The platform body is provided with at least one walking mechanism. The walking mechanism drives the platform body to walk. The drilling and hoisting integrated drilling machine is arranged at the middle portion of the platform body. A construction opening going deep into the platform body by a certain distance is formed in at least one side of the platform body. The in-depth positions of the construction openings are located under a drilling machine body of the drilling and hoisting integrated drilling machine, and the construction openings are matched with drill rods of the drilling machine body in size. The self-walking type island foundation construction platform with the drilling and hoisting device is easy to operate, stable and reliable in platform and capable of guaranteeing the pile forming quality, guaranteeing the rapid and accurate platform positioning, greatly saving the construction time, and greatly reducing the construction cost and the workload.

Description

technical field [0001] The invention relates to a self-propelled island and reef foundation construction platform with drilling and crane equipment. 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 ...

Problems solved by technology

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.
