Description

本発明は、既設の水路トンネルや開水路の内壁面のプレキャストパネルによる補修方法および補修用パネルに関するものである。   The present invention relates to a repair method using a precast panel on an inner wall surface of an existing waterway tunnel or an open waterway, and a repair panel.
老朽化が進んだ水路内壁面をプレキャストパネルにより補修する方法として、FRPM板(強化プラスチック複合板)を用い、内壁面の傷みが激しい水路・断面が大きい水路では、内壁面に支持鋼材を取り付け、これにFRPM板をボルトで固定し、このFRPM板と水路内壁面との間にグラウトを注入して一体化し、水路壁面の傷みが少ない場合・流量アップを目的とする場合には、水路内壁面にFRPM板を接着剤とアンカーで直接固定する方法、あるいは、レジンコンクリート板を用い、水路内壁面との間に接着剤を注入する方法がある。   As a method of repairing an aged channel wall with a precast panel, an FRPM plate (reinforced plastic composite plate) is used. In a channel with a severely damaged inner channel or a large channel, a supporting steel material is attached to the inner wall. If the FRPM plate is fixed with bolts, and grout is injected and integrated between the FRPM plate and the inner wall surface of the water channel, and the water channel wall surface is less damaged, or if the purpose is to increase the flow rate, the inner wall surface of the water channel There are a method of directly fixing the FRPM plate with an adhesive and an anchor, or a method of injecting an adhesive between the inner wall surface of the water channel using a resin concrete plate.
また、FRP板やFRPM板を用いる先行技術文献としては、例えば特許文献1〜4などがある。このうち、特許文献1の水路内面のライニング工法では、水路内面にスペーサー(ゴム製筒状体の中にパテ状接着剤を充填したもの)を介してFRP板を張設し、FRP板を押圧することで、スペーサーの接着剤を突出させて水路内面にFRP板を固定し、ゴム製筒状体で水路内面の凹凸を吸収する。FRP板の適宜箇所をボルト式ねじ込みアンカーや叩き込みアンカーで水路内面にビス止めし、FRP板と内面の間隙に無収縮モルタルを打設する。FRP板の裏面にはアンカーを設けてモルタルとの一体化を図る。   Further, as prior art documents using the FRP plate or the FRPM plate, there are, for example, Patent Documents 1 to 4. Among them, in the lining method for the inner surface of the water channel of Patent Document 1, an FRP plate is stretched on the inner surface of the water channel via a spacer (a rubber tubular body filled with putty-like adhesive), and the FRP plate is pressed. By doing so, the adhesive of the spacer is projected to fix the FRP plate to the inner surface of the water channel, and the irregularities on the inner surface of the water channel are absorbed by the rubber cylindrical body. An appropriate portion of the FRP plate is screwed to the inner surface of the water channel with a bolt-type screw anchor or a hammer anchor, and a non-shrink mortar is placed in the gap between the FRP plate and the inner surface. An anchor is provided on the back surface of the FRP plate to achieve integration with the mortar.
レジンコンクリート板を用いる先行技術文献としては、例えば特許文献5があり、この水路の更正構造およびその施工方法では、レジンコンクリート製のパネル(底面パネル・側面パネル・ヒンジ構造の角部パネル)を用い、底面パネル・角部パネルを板材スペーサー・敷砂の上に設置し、底面パネルに接着剤で接続した左右一対の角部パネルを水平サポートで保持し、樹脂系接着剤を水路側面に沿って流下させ、底面パネル・角部パネルと水路内面との間に注入し、敷砂に浸透させることでレジンコンクリートを形成する。次に、角部パネルに接着剤で接続した左右一対の側面パネルを水平サポートで保持し、樹脂系接着剤を上方から側面パネルと水路内面との間に注入する。   As a prior art document using a resin concrete plate, for example, there is Patent Document 5, and in this water channel correction structure and construction method, a resin concrete panel (bottom panel, side panel, hinged corner panel) is used. The bottom panel / corner panel is placed on the plate spacer / laying sand, and the left and right corner panels connected to the bottom panel with an adhesive are held by the horizontal support, and the resin adhesive is placed along the side of the waterway. The resin concrete is formed by letting it flow down, pouring between the bottom panel / corner panel and the inner surface of the water channel and infiltrating the sand. Next, a pair of left and right side panels connected to the corner panel with an adhesive is held by a horizontal support, and a resin adhesive is injected between the side panel and the water channel inner surface from above.

また、本発明では、パネル10のトンネル幅方向の両端部をトンネル側壁面に沿って隙間をおいて立ち上げ、この立ち上がり片13とトンネル側壁面との間の隙間から裏込め材としてモルタル40を注入し、自然流下により充填する。ねじ込み式アンカー23がパネルの支保工を兼ねる。   Further, in the present invention, both end portions of the panel 10 in the tunnel width direction are raised with a gap along the tunnel side wall surface, and the mortar 40 is used as a backing material from the gap between the rising piece 13 and the tunnel side wall surface. Inject and fill by natural flow. The screw-type anchor 23 also serves as a panel supporter.
一例として、覆工厚20mmに対して、板パネル10の本体部分の板厚は10mm、裏込め厚は10mmである。また、凸部11の突出高さは6mmであるため、4mmの隙間に高さ調整用のゴム板30が配置される。このゴム板30は、板厚が例えば10mmで圧縮率の高い緩衝ゴムを使用する。例えばCR(クロロプレン)系ゴムスポンジ(100×100×10mmの板)の場合、荷重2kNで圧縮率60%、最大で圧縮率約80%が得られる。   As an example, with respect to the lining thickness of 20 mm, the plate thickness of the main body portion of the plate panel 10 is 10 mm, and the backfill thickness is 10 mm. Moreover, since the protrusion height of the convex part 11 is 6 mm, the rubber plate 30 for height adjustment is arrange | positioned in the clearance gap of 4 mm. The rubber plate 30 is made of a buffer rubber having a thickness of, for example, 10 mm and a high compression rate. For example, in the case of CR (chloroprene) rubber sponge (100 × 100 × 10 mm plate), a compression rate of 60% is obtained at a load of 2 kN, and a compression rate of about 80% is obtained at the maximum.
ねじ込み式アンカー23は、穿孔口12・アンカー孔20と同一径のプラスチック系筒体のアンカー21と、これにねじ込まれるステンレス製のネジ22からなり、ネジ22は皿ネジが好ましい。パネル凸部11の穿孔口12から覆工コンクリート2を穿孔し、アンカー孔20から切粉をブロア等で排出し、アンカー21・ネジ22を挿入打設し、挿入が完了してからネジ22をドライバーで締め付ける。このねじ込み式アンカー23の使用目的は、(1)パネル10の位置決め固定、(2)裏込め注入時の支保、(3)長期の剥がれ防止である。   The screw-in type anchor 23 includes a plastic cylindrical anchor 21 having the same diameter as the perforated opening 12 and the anchor hole 20 and a stainless steel screw 22 screwed into the anchor 21. The screw 22 is preferably a countersunk screw. The lining concrete 2 is drilled from the drilling port 12 of the panel projection 11, the chips are discharged from the anchor hole 20 with a blower, the anchor 21 and the screw 22 are inserted, and the screw 22 is inserted after the insertion is completed. Tighten with a screwdriver. The purpose of use of the screw-in type anchor 23 is (1) positioning and fixing of the panel 10, (2) support at the time of backfill injection, and (3) long-term peeling prevention.
パネル端部を立ち上げて立ち上がり片13を設ける目的は、(1)自然流下方式による裏込め材の打設口、(2)既設覆工コンクリート湧水の処理ホースの配置・水の噴出口、(3)既設水路トンネルの施工誤差吸収・クリアランス確保である。この立ち上がり片13とトンネル側壁面との間の隙間から裏込めモルタル40を注入し、自然流下によりパネル10と覆工コンクリート2の間に充填する。裏込めモルタル40は、仕上がり高さから20〜30mm低く打ち上げ、最終仕上げとしてポリマーセメントモルタル41等を上部隙間に充填する。   The purpose of setting up the rising piece 13 by raising the edge of the panel is (1) placement port of backfilling material by natural flow method, (2) arrangement of existing lining concrete spring treatment hose, water outlet, (3) Absorb construction errors and secure clearance for existing waterway tunnels. The backfill mortar 40 is injected from the gap between the rising piece 13 and the tunnel side wall surface, and is filled between the panel 10 and the lining concrete 2 by natural flow. The backfill mortar 40 is launched 20-30 mm lower than the finished height, and a polymer cement mortar 41 or the like is filled in the upper gap as a final finish.
パネル10と覆工コンクリート2の間の最小隙間の寸法は、覆工厚20mmの内、凸部の板厚が16mmであるため、4mmとなり、フロー試験(JIS R 5201 落下なし)のフロー値は250mm以上が必要となる。また、インバート部では、水路部底面に流水が存在し湿潤状態にあることが想定される。このことにより、裏込めモルタル40には、流動性が高く、充填性に優れ、さらに水中不分離性を備えるものを用いる。例えば、水セメント比W/Cを50%とし、減水剤・増結剤を適量加える。圧縮強度は材齢28日で40N/mm以上が得られる。 The minimum clearance between the panel 10 and the lining concrete 2 is 4 mm because the thickness of the convex part is 16 mm within the lining thickness of 20 mm, and the flow value of the flow test (JIS R 5201 no drop) is More than 250mm is required. Moreover, in an invert part, it is assumed that flowing water exists in the bottom face of a water channel part, and is in a moist state. For this reason, the backfill mortar 40 is used which has high fluidity, excellent filling properties, and further has non-separability in water. For example, the water cement ratio W / C is 50%, and an appropriate amount of a water reducing agent and a binder is added. A compressive strength of 40 N / mm 2 or more is obtained at a material age of 28 days.
パネル10同士のピース間・リング間の接合部の上面には、面取りを施し(図2(f)、(g)参照)、適当な漏れ防止処置を配置して接合する。   Chamfering is performed on the upper surface of the joint between the pieces of the panels 10 and between the rings (see FIGS. 2 (f) and 2 (g)), and appropriate leakage prevention measures are arranged and joined.
なお、パネル10は、超高強度繊維補強コンクリート製品の成形用型枠で大量生産することができる。この成形用型枠は、対向配置された竪配置の型枠鋼板の一方の型枠鋼板の内面にパンチングメタルを添設し、このパンチングメタルの表面に織物や不織布の通気性シートを接着剤により貼設し、コンクリートを竪打ちした後、型枠全体をパンチングメタル・通気性シートが上になるように90°回転させて水平状態とし、上に集まった気泡が通気性シート・パンチングメタルを通して排気される構造のものを用いることができる。薄肉のパネル10の表面は気泡のない鏡面が得られ、背面(裏込め材と接触する部分)にはパンチングメタルの多数の小孔により凹凸模様が形成され、付着強度が向上する。型枠鋼板は多段に積層することで、良好な超高強度繊維補強コンクリートパネルが大量生産される。   In addition, the panel 10 can be mass-produced with a mold for forming an ultra-high-strength fiber reinforced concrete product. This forming mold is formed by attaching a punching metal to the inner surface of one form steel plate of a saddle-arranged form steel plate facing each other, and a woven or non-woven breathable sheet on the surface of the punching metal with an adhesive. After pasting and hammering concrete, the entire formwork is rotated 90 ° so that the punching metal / breathable sheet is on top, and the air bubbles gathered above are exhausted through the breathable sheet / punching metal. Can be used. The surface of the thin panel 10 has a mirror-free surface, and a concave-convex pattern is formed on the back surface (portion in contact with the backfill material) by a large number of small holes in the punching metal, thereby improving the adhesion strength. By stacking the form steel plates in multiple stages, a good ultra-high strength fiber reinforced concrete panel is mass-produced.
図4の実施形態においては、開水路1の内壁面のうちの底部1aと側壁部分1c下部の覆工コンクリート2の表面を本発明に係るプレキャストコンクリートパネル10で補修する。側壁部分1cの上部内壁面は、ポリマーセメントモルタル等と無機常温硬化型塗料等からなるコーティング膜3で補修される。このような図示例に限らず、断面全周をパネル10で補修することもできる。   In the embodiment of FIG. 4, the surface of the lining concrete 2 below the bottom 1a and the side wall 1c of the inner wall surface of the open channel 1 is repaired by the precast concrete panel 10 according to the present invention. The upper inner wall surface of the side wall portion 1c is repaired with a coating film 3 made of polymer cement mortar or the like and an inorganic room temperature curing paint or the like. Not only the illustrated example but also the entire cross section can be repaired by the panel 10.
パネル10は、平板状のパネル本体の両端部に立ち上がり片13を設けた断面溝型であり、また立ち上がり片13にも固定用の凸部11が設けられている。その他の点は、水路トンネルの場合と同様であるため、部材に同一符号を付して説明を省略する。   The panel 10 has a cross-sectional groove shape in which rising pieces 13 are provided at both ends of a flat panel main body, and the rising pieces 13 are also provided with convex portions 11 for fixing. Since the other points are the same as in the case of the waterway tunnel, the same reference numerals are given to the members and the description thereof is omitted.
以上のような構成のプレキャストコンクリートパネル10を用いて例えば次のような手順で水路の補修を行う。以下は水路トンネルの場合であり、開水路の場合も同様に行うことができる。   Using the precast concrete panel 10 having the above configuration, for example, the water channel is repaired by the following procedure. The following is the case of a waterway tunnel, and the same can be done for an open waterway.
(1) 坑内準備工
トンネル内に測量ポイントを設置する。トンネルセンターの墨出し、トンネル内部の凹凸形状の確認測量を行う。測定点はトンネル底部のセンター位置とし、10m毎にセンター釘を設置する。また、側壁にも高さ基準釘を10m毎に設置する。
(1) Underground preparation work Survey points will be installed in the tunnel. Checking the tunnel center and confirming the uneven shape inside the tunnel. The measurement point is the center position at the bottom of the tunnel, and a center nail is installed every 10m. Also, height reference nails are installed on the side walls every 10 m.
(2) パネルの運搬
トンネル内に枕木とレールを設置し、運搬台車にパネルを積み込み、パネルの設置位置まで運搬する。運搬台車にはトンネル内移動台車を乗せ、この上にパネルを積み込む。トンネルの底面上を移動する移動台車によりパネルを設置箇所に分配して降ろす。
(2) Transporting panels Install sleepers and rails in the tunnel, load the panels on the transport cart, and transport them to the panel installation position. A transport cart in the tunnel is placed on the transport cart, and a panel is loaded on it. Distribute the panels to the installation site by the moving carriage that moves on the bottom of the tunnel.
(3) パネルの設置
トンネルセンター釘に水糸を取付け、トンネル軸方向の位置確認を行い、パネルの位置決め確認を行う。パネルの高さ確認は、高さ基準釘で確認して設置を行う。パネル設置前には、パネル10の裏面の凸部11に高さ調整用のゴム板30を取付けておく。パネルの設置は、底部と側壁に設置された水糸とスケールで高さを確認して行う。トンネル底部が凹凸しているときは、ライナーをかませて高さ調整し設置を行う。順次、トンネル軸方向にパネル設置を行う。このパネルの設置と平行してねじ込みアンカー23の打設を行う。この際、パネルの高さを再度確認しながら、ネジ22を締め付け、高さ調整用のゴム板30を圧縮させて固定する。これにより、既設トンネル底面の凹凸を吸収することができ、またパネル間の段差もなく、平坦なパネル補修面が得られる。
(3) Panel installation Attach a water thread to the tunnel center nail, confirm the position in the tunnel axis direction, and confirm the panel positioning. Check the height of the panel using the height reference nail. Prior to panel installation, a height adjusting rubber plate 30 is attached to the convex portion 11 on the back surface of the panel 10. The panel is installed by checking the height with the water string and scale installed on the bottom and side walls. If the bottom of the tunnel is uneven, place the liner and adjust the height. Sequentially, panels are installed in the tunnel axis direction. In parallel with the installation of this panel, the threaded anchor 23 is driven. At this time, while confirming the height of the panel again, the screw 22 is tightened and the rubber plate 30 for height adjustment is compressed and fixed. Thereby, the unevenness | corrugation of the existing tunnel bottom face can be absorbed, and there is no level | step difference between panels, and a flat panel repair surface is obtained.
(4) 裏込めモルタル注入
パネル10のピース間・リング間のジョイント位置に漏れ防止処置を行う。この漏れ防止処置の時期は、パネル設置時にその都度行う。トンネル軸方向(リング接合方向)の裏込め注入の妻止めは、パネルの端部に漏れ防止パッキン材を設置する。裏込めモルタル40は、モルタルミキサーで練り混ぜ、注入箇所まで圧送し、パネルの立ち上がり片13とトンネル側壁面との間の隙間から直接上部から注入し、自然流下によりパネル10と覆工コンクリート2の間に充填する。裏込めモルタル40の硬化後、最終仕上げとしてポリマーセメントモルタル41を上部隙間に充填する。
(4) Backfill mortar injection Prevent leakage at the joint position between the pieces of the panel 10 and between the rings. This leakage prevention measure is performed each time the panel is installed. To prevent backfill injection in the tunnel axis direction (ring joining direction), install a leak-proof packing material at the end of the panel. The backfill mortar 40 is kneaded with a mortar mixer, pumped to the injection point, injected directly from the upper part through the gap between the rising piece 13 of the panel and the side wall of the tunnel, and the natural flow of the panel 10 and the lining concrete 2 Fill in between. After the back-filling mortar 40 is cured, the polymer cement mortar 41 is filled in the upper gap as a final finish.
なお、湧水処理方法は、湧水箇所にビニールホースを取付け、立ち上がり片13とトンネル側壁面の間を通し、上部へ導水する。湧水箇所周辺は、止水セメントで止水する。パネル設置後、裏込めモルタルを注入し、ポリマーセメントモルタルで最終仕上げした後、ビニールホースをカットする。   In the spring water treatment method, a vinyl hose is attached to the spring water spot, and the water passes through between the rising piece 13 and the side wall surface of the tunnel and is guided to the upper part. The area around the spring is stopped with water-cement cement. After installing the panel, inject backfilling mortar, finish with polymer cement mortar, and cut vinyl hose.
