摘要： PURPOSE: To provide an underwater shield excavation construction method suitable for the protection of natural environment in which a shield excavation into water can be safely performed within a short period at low construction cost. CONSTITUTION: A starting shaft 20 is constructed in a shield starting position. A cut-of lid 22 at the arrival of a shielding machine 36 is formed in an excavation arriving position going into water. A shield excavation is performed by the shielding machine 36 from the starting shaft 20 to the lid 20 formed in the excavation arriving position, and the cut-off for the shielding machine 36 is performed by the lid 22. The shielding machine 36 is disassembled in the excavation arriving position with the outer shell of the shielding machine 36 being left. After the disassembling of the shielding machine 36, the lid 20 is removed from underwater.

摘要： PURPOSE: To shorten a construction period by starting a shielding machine from a starting shaft toward the sea side, injecting water into a pit after excavation just before a position going into the sea, and further pushing out the shield machine by remote control followed by recovery. CONSTITUTION: When a channel tunnel 18 for running the water of a river 14 into the sea 12 at flooding is excavated, a shield machine is started from a starting shaft 20 on the land side, and conducts excavation just before a position going into the sea 12. Water is injected into the tunnel 18 in this state, and the shield machine is pushed out into the sea 12, and then recovered. The cut-off work at the communication between the pit and underwater is dispensed with, an arriving shaft is also dispensed with, and the construction period is shortened to reduce the cost. Thus, the channel tunnel can be easily and safely excavated.

摘要： PURPOSE: To provide a tunnel penetrating construction method to underwater by which water can be reliably stopped and construction work can be safely performed in a short time and construction work cost is reduced and which is suitable for the protection of a natural environment when a tunnel is penetrated to underwater. CONSTITUTION: A departing shaft 20 is constructed in a shielding departing position. Shielding excavation is propelled up to a position close to a beach line T from the departing shaft 20 while assembling a segment 26. While connecting a propelling pipe 30 to a tail part 28 of a shielding machine 24 in the segment 26 in a position close to the beach line T, the propelling pipe 30 is propelled by a propelling jack 34 arranged in the segment 26, and the shielding machine 24 is made to reach underwater. Water is stopped by installing a sealing cover on the propelling pipe 30 in an underwater reaching position. After the propelling pipe 30 is sealed by the sealing cover, the shielding machine 24 is separated from the propelling pipe 30, and is taken out from underwater. After the shielding machine 30 is taken out, the sealing cover of the propelling pipe 30 is removed from underwater.

CONSTITUTION: A starting shaft 20 is constructed in a shield starting position. A shield excavation is performed from the starting shaft 20 to just before an excavation arriving position going into water. A sealing lid is mounted on a shield segment just before the excavation arriving position to cut off water. After the sealing of the shield segment by the sealing lid, a shielding machine 36 is separated and removed from in water after the removal of the shielding machine 36, the sealing lid of the shield segment is removed from underwater.

摘要： PURPOSE:To facilitate a construction work of breakwaters by assembling a breakwater structure composed of vertical perforated walls, horizontal perforated plates and a frame structure, arranging the breakwater structure on a submarine ground at the given site and driving piles through holes in the structure into the ground to form the integrated breakwater structure. CONSTITUTION:Vertical perforated walls 2 made of concrete has a number of bores 7 through which water passes. Horizontal perforated plates 3 made of concrete also has a number of bores through which water passes. Vertical walls 2 and horizontal plates 3 are connected together to a frame structure which is composed of beam members 4 made of steel or concrete and pillar members made of steel or concrete and having pile-passing holes. Foundation piles 1 are driven through the holes into a submarine ground 6 and fixed thereon.

CONSTITUTION:Mortar is made of admixture containing calcium chloride as a main component and a kind of salt such as salt containing iron as an auxiliary component. In the next step, this mortar is mixed with grain-like body to be disposed formed of hard foam polyurethane broken into fragments and banking soil to form a banking base body 3. This constitution makes it possible to strongly integrate the banking base body 3 and to construct the banking base body 3 for concreting in site at any place where is excellent in chemical resistance, permeability and water holding property.
