Embodiment Construction

[0072] figure 1 A buried tunnel 1 laid on soil 2 under a body of water 3 is shown very schematically. The tunnel comprises two approach sections 1a, 1b extending onto the ground, for example the banks or embankments 4 and 5 of the body of water 3, and a main submerged section 1c. After completion of construction, the tunnel has been covered with (optional) protective filling K.

[0073] The submerged part of the tunnel and preferably the approach part extending above ground and the slightly submerged part are built from successive pipe sections whose cross-section is determined in a known manner according to the use of the tunnel.

[0074] In this example, Figure 2 to Figure 6 The cross-sectional diagram of shows a standard pipe section with a cross-section constituting an "8"-shaped double-lane, double-compartment tunnel.

[0075] According to the invention, the tunnel is built in successive pipe sections with a unit length of about 1 meter.

Abstract

The invention relates to a method and equipment for constructing a submerged tunnel on seabed soil. The tunnel is constructed by moving successive tunnel sections over the subsea soil in water by a machine (M) adapted to operate on land and in immersion, including fluid-tight work for the accommodation of the crew and the installations required for construction Space (6) with openings to the rear for building and installing pipe sections at the rear of the machine, which includes at its front equipped with devices for preparing and leveling the soil in preparation for installing pipe sections (21 -23) ballastable tank (7). The invention relates to the application of building tunnels at the bottom of bodies of water.

Description

technical field [0001] The present invention relates to constructing (constructing) buried tunnels under water bodies. Background technique [0002] A number of techniques have been proposed for constructing tunnels under bodies of water, usually under sea water. [0003] Some techniques relate to the construction of tunnels mainly under the ground at the bottom of bodies of water, such as described in publications DE50882, JP9316901, GB348204, EP0899422, JP09-273382, JP2024489, US1441698 and US4889448. [0004] In fact, when used to build tunnels through mountains, a common solution in such cases consists in using a tunnel boring machine to drill the soil, moving the drilled material to the rear of the tunnel boring machine, as the tunnel progresses The advancement of the machine builds the tunnel with successive pipe sections (pipe sections). [0005] Tunnels built in this way under the bottom of the water body have the advantage of not constituting a hindrance to water ...
