【産業上の利用分野】[Industrial applications]

本考案は、シールド工法による小口径トンネル工事において、トンネル内径が異 なる場合にも汎用的に使用することの出来る、トンネル内レール仮設用の汎用枕 木セットに関するものである。 The present invention relates to a general-purpose sleeper set for temporary installation of rails in a tunnel, which can be generally used even when the inner diameter of the tunnel is different in the small-diameter tunnel construction by the shield construction method.

【０００２】[0002]

【従来の技術】[Prior art]

シールド工法によるトンネル工事においてはトンネルを掘削しながらユニットセ グメント（１０１）を順次敷設し、セグメントとセグメントをフランジ（１０２ ）で接続し、縦方向に隣り合う単位セグメントのフランジ上に跨がってレール仮 設用枕木を設置し、資材運搬用台車、土砂搬出用車両を走行させる為のレール（ １０３）（１０４）を敷設する事が行われている。またこれら枕木上には作業者 の歩行を容易にするため通常歩行用足場板も載せられている（１０５）。 In the tunnel construction by the shield method, unit segments (101) are laid one after another while excavating the tunnel, the segments are connected by flanges (102), and rails are spread over the flanges of the unit segments that are vertically adjacent to each other. Temporary sleepers are installed and rails (103) and (104) for laying trucks for carrying materials and vehicles for carrying out earth and sand are laid. In addition, scaffolding boards for normal walking are placed on these sleepers to facilitate the walking of workers (105).

【０００３】 大口径トンネルは別として、下水道トンネルその他多くの小口径シールド工法ト ンネルでは内径が１８００ｍｍ、２０００ｍｍおよび２１５０ｍｍと規格化され たトンネルが多用されている。従来こういったトンネルの場合レールおよび足場 板を載せるための必要なスペースを確保するには枕木の全長として約１３５０ｍ ｍ程度が必要であるためレール載せ部と歩行用足場板載せ部を同じ高さとすれば 、足場板上の有効歩行高さは約１５００ｍｍ程度となり歩行に困難を伴う。そこ で通常足場板載せ部をレール載せ部より一段下げて歩行容易にすることが、例え ば実開昭、５１−３２８０１号記載の如く古くから行われてきた。Apart from large-diameter tunnels, sewer tunnels and many other small-diameter shield construction tunnels often use standardized inner diameters of 1800 mm, 2000 mm, and 2150 mm. In the case of conventional tunnels, the total length of sleepers needs to be about 1350 mm in order to secure the necessary space for mounting the rails and scaffolding plates. Therefore, the rail mounting part and the walking scaffolding plate mounting part should have the same height. Then, the effective walking height on the scaffolding plate is about 1500 mm, which makes walking difficult. For this reason, it has long been practiced to lower the scaffolding board mounting section from the rail mounting section by one step to facilitate walking, as described in, for example, Jitsukaisho, 51-32801.

【０００４】 また枕木を隣り合う単位セグメントのフランジ上に跨がって載せて固定したり、 使用後に撤去を容易にするためトンネル主桁に嵌まりこむ切欠を枕木鋼材の端縁 に設けることも業界においてはＨ鋼枕木等で古くから行われてきたところである 。なおこういった公知技術を集め、足場板載せ部をレール載せ部より一段低くし て有効歩行高さを確保し、また枕木の設置ならびに撤去を容易にするものとして 実公平７−２１６８０号にはセグメントトンネルの内面に沿う円弧状に湾曲した 当て板上に、当て板の両端に跨がって載せ板を固定し、載せ板はレールを載せる レール載せ部と、それより低く形成され歩行用足場板を載せる足場板載せ部を具 え、両端にはセグメントのフランジの内縁が嵌まる切欠が施されているセグメン トトンネル内レール仮設用枕木が記載されている。 しかしながら実公平７−２１６８０号記載の枕木はセグメントトンネルの内面に 沿う円弧状に湾曲した当て板に載せ板が一体に溶接固定された構成となっていて 工事現場までこの嵩高い枕木を運搬する必要があるし、またトンネル内径が異な る毎に、別々の枕木群を用意せねばならぬ問題点をかかえている。Further, the sleepers may be mounted by straddling the flanges of the unit segments adjacent to each other, or a cutout that fits into the tunnel main girder may be provided at the edge of the sleeper steel material to facilitate removal after use. In the industry, H steel sleepers have been used for a long time. It should be noted that, as a collection of such publicly known technologies, the scaffolding board mounting part is made one step lower than the rail mounting part to ensure an effective walking height, and the installation and removal of sleepers is facilitated in Jpn. On a backing plate curved in an arc along the inner surface of the segment tunnel, the backing plate is fixed across both ends of the backing plate, and the backing plate is a rail mounting part on which a rail is mounted, and a walking scaffold formed lower than that. Scaffolds for placing boards The railroad temporary sleepers for segment rails in the segment tunnel are described with notches for fitting the inner edges of the segment flanges at both ends. However, the sleeper described in Japanese Utility Model Publication No. 7-21680 has a structure in which the mounting plate is integrally welded and fixed to the arc-shaped curved backing plate along the inner surface of the segment tunnel, and it is necessary to transport this bulky sleeper to the construction site. However, there is a problem that a separate sleeper group must be prepared for each different tunnel inner diameter.

【０００５】 さらに所謂小口径シールド工法トンネルではトンネル掘削時には１本レールの資 材運搬用の後方台車と、２本レールの土砂運搬用の車両とを走行させるため、土 砂運搬用車両のレールはトンネル中央から偏った位置に設けられるが、トンネル 掘削の後、壁面をコンクリート被覆する目的で作業車を走行させる場合には、作 業車が大型であるため、その走行用レールはトンネル中央に敷設しなおす必要が 生じる。この際には資材運搬用の後方台車用レールは不必要で撤去せられる。Further, in a so-called small-diameter shield construction method tunnel, when a tunnel is excavated, a rear truck for carrying material of one rail and a vehicle for carrying earth and sand of two rails travel, so the rail of the vehicle for carrying sand and sand is Although it is installed at a position deviated from the center of the tunnel, when the work vehicle is run for the purpose of covering the wall surface with concrete after tunnel excavation, the running rail is laid in the center of the tunnel because the work vehicle is large. It will be necessary to rework. In this case, the rail for the rear carriage for material transportation is unnecessary and can be removed.

【０００６】 従ってトンネル枕木はこのようなトンネル掘削時ならびに掘削後の車両走行位置 の変更、レール取り替えに好都合に対応できるものであることが必要である。 かかる要望に応えるものとして、足場板載せ部に上面に補助レール載せ部を有す る移動台がトンネルの幅方向に移動且つ位置決め固定可能に配備されているトン ネル内レール仮設用枕木が提案されている（実公平７−８６３９号）。Therefore, it is necessary for the tunnel sleeper to be able to conveniently cope with such changes in the vehicle traveling position and exchanging rails during and after tunnel excavation. In order to meet such demands, a rail sleeper for temporary installation in the tunnel has been proposed in which a moving platform having an auxiliary rail mounting part on the top surface of the scaffolding plate mounting part is arranged so that it can be moved and positioned and fixed in the width direction of the tunnel. (Actual fair No. 7-8639).

【０００７】 しかしながら上記考案にかかる移動台はレール載せ部を有する枕木本体とは独立 した台であるため、レール取り替え以外に、作業毎に移動台を枕木本体から取り 外し、トンネルの幅方向に移動し、再度枕木本体に取り付ける煩雑な作業を必要 とする。However, since the moving stand according to the above invention is a stand independent from the sleeper body having the rail mounting portion, the moving stand is removed from the sleeper body for each work and moved in the width direction of the tunnel in addition to the rail replacement. However, the complicated work of reattaching it to the sleeper body is required.

【０００８】[0008]

【考案が解決しようとする課題】 そこで本考案は足場板の支持高さをレール敷設高さより低くし、作業者の自由な 行動を保証することが出来、敷設・撤去が容易な枕木であり、しかも現場までの 運搬も容易であるばかりか、口径の異なるトンネル工事においても汎用的に使用 することの出来る小口径シールド工法トンネル用の枕木セットを提供することが 目的の一つである。 さらにまた煩雑な作業を必要とすることなく、トンネル掘削時ならびに掘削後の 車両走行位置の変更、レール取り替えが容易になしうるトンネルのレール仮設用 枕木を組み立てることのできる枕木セットを提供することも本考案の目的の一つ である。[Problems to be solved by the invention] Therefore, the present invention is a sleeper that can lower the supporting height of the scaffolding plate lower than the rail laying height, guarantee the free action of the worker, and can be easily laid and removed. Moreover, one of the aims is to provide a sleeper set for a tunnel with a small-diameter shield construction method, which is not only easy to transport to the site but also can be used for general purpose in tunnel construction with different diameters. Furthermore, it is possible to provide a sleeper set that can assemble railroad temporary sleepers for tunnels that can easily change the vehicle traveling position and exchanging rails during and after tunnel excavation without requiring complicated work. This is one of the purposes of the present invention.
