In the service passage 6, an emergency vehicle of a shuttle type 9 for enabling personal access and evacuation of persons is hung on the slab 3 for the occurrence of an accident or a fire in the tunnel. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

［背景技術］
トンネル掘削機を用いた車道トンネルの建設は、経済的な理由および環境に関する理由の双方から、漸増している問題解決策である。この技術によれば、掘削機で表土を掘り進み、セグメント化されたプレキャスト・タイプの外構材を配設し、トンネルの壁面を形成して円形にしてゆく。これに続いて、並設対面通行ができる車輌走行用プラットフォームを造るために、トンネル底部にフィリングが施工される。 [Background technology]
The construction of road tunnels using tunnel excavators is an increasing problem solution for both economic and environmental reasons. According to this technology, the excavator excavates the top soil, disposes the segmented precast type exterior material, forms the wall surface of the tunnel and makes it circular. Following this, a filling is constructed at the bottom of the tunnel in order to build a vehicle travel platform that allows side-by-side traffic.

片側１車線以上のトンネルでは、必要な径を既存のトンネル掘削機では処理できない。更に、長いトンネルの場合も、安全上の理由からこの解決策には問題があり、一般的に一方向ごとに別々のトンネルを二本造ることが必要である。また、トンネル内での事故や火災に際して人員が避難できるようにするために、トンネルに沿って一定間隔で避難路及び／又は縦坑を造ることも必要である。   In tunnels with more than one lane on one side, the required diameter cannot be handled by existing tunnel excavators. In addition, even for long tunnels, this solution is problematic for safety reasons, and it is generally necessary to build two separate tunnels for each direction. It is also necessary to build evacuation paths and / or shafts at regular intervals along the tunnel so that personnel can evacuate in the event of an accident or fire in the tunnel.

ＷＯ２００４／０９４７８５は、二本の独立した車線を有する円形トンネルに関するものであり、それぞれが通行路となっているが、これらは非常に異なっており、依然として第二のトンネルを造る必要が有る。ＥＰ１１９１１８６Ａ１も、分離壁が設けられた二階建ての円形の車道トンネルに関するものであるが、各レベルが、一方向１車線であり、車の乗客が通行できるのは上側レベルのみである。
ＷＯ２００４／０９４７８５ ＥＰ１１９１１８６Ａ１ WO 2004/094785 relates to a circular tunnel with two independent lanes, each of which is a traffic route, but they are very different and still need to build a second tunnel. EP 1 191 186 A1 also relates to a two-story circular roadway tunnel provided with a separation wall, but each level is one lane in one direction, and the passengers of the car can only pass through the upper level.
WO2004 / 0949485 EP1191186A1

本発明は、円形断面を持ち、両面交通の車道トンネンル建設のための革新的な解決策を構成するものであり、あらゆる通行形態のための、独立した、２本の同一車線を提供するとともに、トンネル内での事故や火災が生じたときの個人用のローカルアクセスと、人々の避難路を確保するために、上記車道と相互に連結したサービス通路を提供する。   The present invention constitutes an innovative solution for the construction of double-sided traffic road tunnels with a circular cross-section, providing two independent and identical lanes for all modes of traffic, In order to secure personal local access in the event of an accident or fire in the tunnel and a evacuation route for people, a service passage interconnected with the above roadway is provided.

本発明は、図１、２、３、４及び５に図解されている。
図１は、トンネルの見取図である。 図２は、運行中のトンネル断面を示す。 図３は、上下の連絡通路部分の縦方向のトンネル断面を示す。 図４は、トンネルの長手方向断面である。 図５は、上層車道におけるトンネルの平面を示す。 The present invention is illustrated in FIGS.
FIG. 1 is a sketch of a tunnel. FIG. 2 shows a tunnel cross section during operation. FIG. 3 shows a longitudinal tunnel cross section of the upper and lower connecting passage portions. FIG. 4 is a longitudinal section of the tunnel. FIG. 5 shows a plane of the tunnel in the upper-layer roadway.

トンネル掘削機で表土を掘り、互いにクランプされているプレキャストセグメントを配設して、円形形状であるトンネル（１）の壁面を形成する。   A top surface is dug with a tunnel excavator, and precast segments clamped to each other are arranged to form a wall surface of the tunnel (1) having a circular shape.

トンネルの内側に、全幅にわたって二枚のスラブ（２）、（３）が形成される。一方はトンネルのほぼ半分の高さに配置し、他方はトンネル底部のやや上方に配置して、それぞれが隔離されて独立した三重層の通路を形成している。２本は、それぞれ車両通行用の同一の車道（４）、（５）であり、一本はサービス通路（６）である。   Inside the tunnel, two slabs (2), (3) are formed over the entire width. One is located approximately half the height of the tunnel and the other is located slightly above the bottom of the tunnel, each being isolated to form an independent triple layer passage. Two are the same roadways (4) and (5) for vehicle traffic, respectively, and one is a service passage (6).

スラブ（２）、（３）には、トンネル（１）の円形壁面近くの片側あるいは両側に、一定間隔で開口部（７）が設けられており、この開口部（７）は避難用ドアの付いたボックスタイプの防火装置（８）によって防護されている。それぞれの側の防火装置（８）は、閉鎖された縦方向の連絡通路（１０）に連結されている。この通路には、車道（４）、（５）とサービス通路（６）との間に人が安全に通ることができる内階段が設けられている。縦方向の連絡通路（１０）は、トンネル（１）の円形の壁を通って延在させてもよい。   The slabs (2) and (3) are provided with openings (7) at regular intervals on one or both sides near the circular wall surface of the tunnel (1). It is protected by a box-type fire protection device (8) attached. The fire protection device (8) on each side is connected to a closed longitudinal communication passage (10). This passage is provided with an inner stairway through which people can safely pass between the roadways (4), (5) and the service passage (6). The longitudinal communication passage (10) may extend through the circular wall of the tunnel (1).

サービス通路（６）内には、スラブ（３）に吊られているシャトル・タイプの緊急用車輌（９）が設置されており、これはトンネル内で事故や火災が生じた場合の個人用のローカルアクセスと、人々の避難手段を提供するものである。   Within the service aisle (6) there is a shuttle type emergency vehicle (9) suspended on the slab (3) for personal use in the event of an accident or fire in the tunnel. It provides local access and a means of evacuating people.
