A tube joint apparatus for a double-tube floating tunnel and a construction method thereof are provided, the apparatus includes a joint device, a tunnel tube body, and an escape device. The escape device is provided in the joint device, the tunnel tube body is respectively connected to left and right ends of the joint device. A plurality of anchor yokes are connected to an outside of the joint device. The joint device includes a watertight locking structure section, a framework connection section, and a main functional section. The main functional section includes a joint inner road surface and a joint housing. The joint inner road surface is provided in the joint housing, and the watertight locking structure section is respectively connected to two ends of the framework connection section. The present disclosure improves a utilization rate of an internal space in the underwater floating tunnel.

An underwater floating pipeline with the ability to self-maintain desired depth beneath the water giving the ability to connect distant locations. The sections maintain and alter buoyancy for repair and maintenance. Multi chambered pipes allow different rates of flow. Automatic snap-shut doors protect against leaks and loss of pressure. Warning systems alert those in proximity to the pipeline. Freight may use the tunnels to avoid adverse surface weather and high shipping cost and fuel and labour savings.
