Abstract

ベアリングブロックによって支持されたトンネルで、軟弱地盤（１）に施工される。トンネルボーリングマシーンによって装頓したプレキャスト部材により作り出される外側チューブ（３）と、外側チューブを外側型枠として使用して設けられており、トンネルの抵抗部材を構成している内側チューブ（４）の二つのチューブを具え、双方共がトンネル軸に沿って規則的な間隔を設けたベアリングブロック（５）によって支持されている。ベアリングブロック（５）は水平方向に大きな可撓性を有する抵抗部材（６）を介して、硬質地盤まで下方向に延在しており、垂直荷重に対して耐性である一方、地震の時にトンネルの水平移動が可能である。
【選択図】図１It is constructed on soft ground (1) in a tunnel supported by bearing blocks. An outer tube (3) created by a precast member arranged by a tunnel boring machine and an inner tube (4) which is provided by using the outer tube as an outer formwork and which constitutes a resistance member of the tunnel. Both tubes are supported by bearing blocks (5) that are regularly spaced along the tunnel axis. The bearing block (5) extends downward to the hard ground via a highly flexible resistance member (6) in the horizontal direction and is resistant to vertical loads, while it is tunneled in the event of an earthquake. Can be moved horizontally.

Description

トンネルボーリングマシーンによるトンネル施工は道路や鉄道輸送システム用の基礎構造建設に用いられる。   Tunnel construction by tunnel boring machine is used for the construction of foundations for road and rail transport systems.

従来のトンネルボーリングマシーンによるトンネル施工は、前記マシーンで地盤を掘削し、プレキャスト部材を設けてトンネル壁面を作るというマシーンによってトンネルを掘削する工程から成る。   Tunnel construction by a conventional tunnel boring machine includes a step of excavating a tunnel by a machine in which the ground is excavated by the machine and a precast member is provided to form a tunnel wall surface.

トンネル建設には、硬質地盤が適当である。なぜなら、この方法においてできたトンネルは、周辺地盤の硬さによってトンネルに安定性が生じ、横方向とトンネル軸の方向の双方に有意な強度を有する必要がなくなるからである。   Hard ground is appropriate for tunnel construction. This is because the tunnel formed by this method has stability due to the hardness of the surrounding ground, and does not need to have significant strength in both the lateral direction and the direction of the tunnel axis.

軟弱地盤の場合、トンネルボーリングマシーンによるトンネル施工は信頼性に欠ける。なぜなら、このように作ったトンネルでは、プレキャスト部材間の連結が非常に弱くなるためである。トンネル強度が低くなり、特に地震時に沈下又は崩壊の危険性がある。   In the case of soft ground, tunnel construction by tunnel boring machine is not reliable. This is because in the tunnel made in this way, the connection between the precast members becomes very weak. Tunnel strength is low, and there is a risk of subsidence or collapse especially during an earthquake.

本発明は、トンネルボーリングマシーンでトンネルを掘削する道路や鉄道型トンネル建設用の革新的な方法であって、このトンネルは軟弱地盤（例えば、泥土）に施工されると、地盤内で橋のような機能を果たす。この方法はまた、内側の強度をつけるために、既存のトンネルを型枠として使用して、既存のトンネルの強化を図ることもできる。   The present invention is an innovative method for constructing roads and railway type tunnels for excavating tunnels in tunnel boring machines, and when this tunnel is constructed on soft ground (eg mud), it is like a bridge in the ground. Fulfills the functions. This method can also be used to strengthen existing tunnels, using the existing tunnel as a formwork to add inner strength.

トンネルは、トンネルボーリングマシーンによって軟弱地盤に作った外側チューブ（３）と、当該外側チューブの内側に後に作る内側チューブ（４）の二つのチューブによって構成されている。   The tunnel is composed of two tubes, an outer tube (3) made on a soft ground by a tunnel boring machine and an inner tube (4) made later inside the outer tube.

トンネルは軟弱地盤（１）中にトンネルの軸に沿って規則的な間隔を設けて取り付けたベアリングブロック（５）によって支持される。   The tunnel is supported by bearing blocks (5) mounted in soft ground (1) at regular intervals along the tunnel axis.

外側チューブ（３）は、トンネルボーリングマシーンによって装頓したプレキャスト部材によってできており、ベアリングブロック（５）を貫通している。外側チューブは、耐性機能はなく、内側チューブ施工用の外側型枠として機能する。   The outer tube (3) is made of a precast member arranged by a tunnel boring machine and penetrates the bearing block (5). The outer tube does not have a resistance function and functions as an outer formwork for inner tube construction.

内側チューブ（４）は、外側チューブの内側に、外側チューブを型枠として使用して施工される。内側チューブ（４）は、外側チューブ（３）の強度を考慮することなく、トンネルに作用する横及び縦方向の作用に対する必要な強度を有する。   The inner tube (4) is constructed inside the outer tube using the outer tube as a mold. The inner tube (4) has the necessary strength for the lateral and longitudinal action acting on the tunnel without considering the strength of the outer tube (3).

ベアリングブロック（５）は、水平方向に大きな可撓性を有する抵抗部材（６）を介して、硬質地盤（２）まで下方向に延在しており、垂直荷重に対して耐性がある一方で、地震の時にトンネルが水平移動できる。   The bearing block (5) extends downward to the hard ground (2) via a resistance member (6) having great flexibility in the horizontal direction, and is resistant to vertical loads. The tunnel can move horizontally during an earthquake.
