Description
本発明は、トンネル外周側の地下水が流出入自在な通水部をトンネル周方向に沿わせて一連に設けるとともに、その通水部端部をトンネル周方向端部に臨ませ、トンネル周方向で隣り合うセグメントの前記トンネル周方向端部どうしを突き合わせて、前記通水部端部どうしが連通するように、互いに連結可能な機械式連結部を設けてあるトンネル用セグメントに関する。 The present invention provides a series of water-passing portions through which the ground water on the outer periphery of the tunnel can freely flow in and out along the circumferential direction of the tunnel, and the end of the water-flowing portion faces the end of the tunnel in the circumferential direction. The present invention relates to a tunnel segment provided with mechanical connecting portions that can be connected to each other so that the end portions of adjacent tunnels face each other in the circumferential direction of the tunnel and the end portions of the water passage portions communicate with each other.
上記トンネル用セグメントは、透水性土壌層に埋設しても、地下水流の遮断を防止できるように、トンネル外周側の地下水が流出入自在な通水部をトンネル周方向に沿わせて一連に設けてあり、トンネル周方向で隣り合うセグメントに亘って地下水が通水できるように、通水部端部をトンネル周方向端部に臨ませて、突き合わせたトンネル周方向端部どうしを、通水部端部どうしが連通するように、互いに連結可能な機械式連結部を設けてあるが、従来、機械式連結部と通水部端部とをセグメント厚さ方向に重複するように、トンネル周方向端部に配置している（例えば、特許文献１参照）。 The above tunnel segments are provided in series along the tunnel circumferential direction so that groundwater on the outer periphery of the tunnel can freely flow in and out, even if buried in a permeable soil layer. In order to allow groundwater to pass through the adjacent segments in the tunnel circumferential direction, the end of the water flow section faces the end of the tunnel circumferential direction, and the tunnel circumferential direction ends that meet each other are connected to the water flow section. A mechanical connecting part that can be connected to each other is provided so that the end parts communicate with each other, but conventionally, the mechanical connecting part and the water passing part end part overlap with each other in the segment thickness direction. It arrange | positions at the edge part (for example, refer patent document 1).
トンネル用セグメントは、トンネル周方向で隣り合うセグメントのトンネル周方向端部どうしを突き合わせて互いに連結したときに、地下水などが突合せ部を通して機械式連結部側やトンネル内側に流入しないように、トンネル周方向端部の機械式連結部よりもトンネル外周側にそれらの突合せ部をシールするシール材を一連に装着する必要があるが、従来の上記トンネル用セグメントによれば、機械式連結部と通水部端部とをセグメント厚さ方向に重複するように配置してあるので、シール材をトンネル周方向端部に一連に装着するには、シール材と機械式連結部と通水部端部とがセグメント厚さ方向に並んで重複する状態で装着する必要がある。
このため、通水部端部における通水量が多くなるように、通水部端部のセグメント厚さ方向の寸法を大きくすると、機械式連結部をトンネル内周側に偏らせて設けて、その機械式連結部と通水部端部との間にシール材を装着する必要があるので、シール材のセグメント厚さ方向での装着幅が狭くなって、シール性を確保しにくい欠点があるとともに、トンネル周方向で隣り合うセグメントの突合せ部に、その突合せ部におけるトンネル内周側端部を支点にして、トンネル外周側端部どうしの間隔を拡げる方向のモーメントが作用したときに、トンネル内周側に偏らせて設けた機械式連結部に大きな引っ張り力が作用するおそれがあり、連結強度を確保しにくい欠点がある。
また、機械式連結部に大きな引っ張り力が作用しても連結強度を確保できるように、機械式連結部をセグメント厚さ方向に並べて配置したり、大型の機械式連結部を配置し、シール性も確保し易いように、シール材のセグメント厚さ方向での装着幅を大きくすると、通水部端部のセグメント厚さ方向の寸法が小さくなって、通水部端部における通水量が少なくなる欠点がある。
更に、通水部端部における通水量が多くなるように、通水部端部のセグメント厚さ方向の寸法を大きくし、機械式連結部に大きな引っ張り力が作用しても連結強度を確保できるように、機械式連結部をセグメント厚さ方向に並べて配置したり、大型の機械式連結部を配置し、シール性も確保し易いように、シール材のセグメント厚さ方向での装着幅も大きくすると、セグメント厚さが極厚になって、セグメントが大型化するとともに、トンネル外径が大きくなって地中掘削量が増大するなどの欠点がある。
本発明は上記実情に鑑みてなされたものであって、セグメント厚さを特に厚くすることなく、通水部端部における通水量を多くすることができる上、機械式連結部の連結強度も、突合せ部のシール性も確保し易いトンネル用セグメントを提供することを目的とする。
Tunnel segments are designed to prevent groundwater from flowing into the mechanical connection side or inside the tunnel through the butted portion when the tunnel circumferential direction ends of adjacent segments in the tunnel circumferential direction are butted together. It is necessary to install a series of sealing materials that seal the butt portion on the outer periphery side of the tunnel from the mechanical connection portion at the direction end, but according to the conventional tunnel segment, the mechanical connection portion and the water flow Since it is arranged so that the end part overlaps with the segment thickness direction, in order to install the sealing material in series on the end part in the circumferential direction of the tunnel, the sealing material, the mechanical connecting part, the end part of the water flow part, Need to be mounted in a state of overlapping in the segment thickness direction.
For this reason, when the dimension in the segment thickness direction of the water flow portion end portion is increased so that the water flow amount at the water flow portion end portion is increased, the mechanical connection portion is biased toward the inner circumferential side of the tunnel, Since it is necessary to install a sealing material between the mechanical connection part and the end of the water flow part, the mounting width in the segment thickness direction of the sealing material becomes narrow, and there is a drawback that it is difficult to ensure sealing performance When a moment in the direction of widening the distance between the tunnel outer periphery side ends is applied to the abutting portion of the adjacent segment in the tunnel circumferential direction, with the tunnel inner peripheral end portion at the butt portion serving as a fulcrum, There is a possibility that a large pulling force may act on the mechanical connecting portion provided so as to be biased to the side, and it is difficult to ensure the connecting strength.
Also, in order to ensure the connection strength even when a large tensile force acts on the mechanical connection part, the mechanical connection parts are arranged side by side in the segment thickness direction, or a large mechanical connection part is provided to improve the sealing performance. If the mounting width of the sealing material in the segment thickness direction is increased, the dimension in the segment thickness direction of the water flow portion end portion is reduced, and the amount of water flow at the water flow portion end portion is reduced. There are drawbacks.
Furthermore, the dimension in the direction of the segment thickness at the end of the water flow portion is increased so that the amount of water flow at the end of the water flow portion increases, and the connection strength can be ensured even if a large tensile force acts on the mechanical connection portion. As described above, the mechanical couplings are arranged side by side in the segment thickness direction, or large mechanical couplings are arranged, so that the seal width is easy to secure and the mounting width in the segment thickness direction is large. As a result, the segment thickness becomes extremely large, the segment is enlarged, and the tunnel outer diameter is increased to increase the amount of underground excavation.
The present invention has been made in view of the above circumstances, and without particularly increasing the segment thickness, the amount of water passing at the end of the water passing portion can be increased, and the connection strength of the mechanical connecting portion is also increased. An object of the present invention is to provide a tunnel segment that can easily secure a sealing property of a butt portion.
