AI Technical Summary

Technical Problem

In the construction of immersed tube tunnels, due to the limited space in the dock, the large volume and heavy weight of the dock door, the floating installation and delivery process of the dock door is very difficult.

Method used

The dock door is driven by a tugboat to tow and hold the dock door, and the predetermined installation point of the dock door is determined by using the belt cable and hold the dock door, and the dock door is sinking into place through the ballast water tank. Finally, the temporary water pump drainage is used to ensure that the dock door water level is lower than the side of the harbor pool.

Benefits of technology

By determining the dock door installation point in advance, the accuracy of the dock door installation position is ensured, and the construction is convenient, and it is suitable for a wide range of dock door floating installation construction.

Abstract

The invention discloses a construction method for floating transportation and installation of a dock gate and a corresponding device, and belongs to the technical field of immersed tube tunnels, and the construction method comprises the following steps: S1, towing the dock gate to a point by using a tug, S2, carrying out mooring and abutting on the dock gate, S3, injecting water into a water ballast tank at the bottom of the dock gate until the dock gate sinks in place, and S4, draining water from a dock entrance after the dock gate sinks in place; construction is conducted through a dock gate consignment and installation method, the dock gate is consigned to a designated point position, and the accuracy of the dock gate installation position is guaranteed in a cabling and abutting mode. The consignment and installation method has the advantages of being high in operability, rapid and convenient to construct, wide in applicability and the like. The defect that in the prior art, floating installation or delivery of the dock gate is very difficult in actual construction is effectively overcome.
