Description

【０００１】
【発明の属する技術分野】
本発明は連続壁の防水装置及び防水方法、特にＨ形鋼やＩ形鋼などの芯材が埋め込まれた連続壁の防水装置及び防水方法に関するものである。
【０００２】
【従来の技術】
ソイルセメント柱列壁または泥水固化壁など（以下連続壁と称する）は仮設用の山留め壁や止水壁として構築され、その中に芯材としてＨ形鋼やＩ形鋼が埋め込まれている。この連続壁は構造物の地下を掘削する前に地下に施工され、その後の掘削により上記連続壁の芯材の前端部までを露出させることにより、地下空間を構築せしめている。
【０００３】
連続壁中に埋め込まれている芯材は本体構造物である地下外壁の構築後に地盤内に埋め殺しされるのが一般的であったが、近年においては、芯材を本体構造物の一部として有効利用するため、芯材のフランジ面にスタッドボルトを打設して外壁と一体化した合成壁工法を用いているが、上記スタッドボルトのため、連続壁の全面に防水シートを貼り付けて防水をはかることができない。そのため上記連続壁の芯材の前端部における防水は、従来においては図１４及び図１５に示すように、上記連続壁１に埋め込まれた各隣り合うＨ形鋼の芯材２の前端部のフランジ３間に鋼板４を溶接したり、図１６に示すように、芯材２の前端部の全面に防水シート５を貼り付けていた。
【０００４】
なお、公知例として特開平５−２２２７４１号公報、特開平８−２９６２４７号公報、特開平７−９０８７５号公報、特開平９−２４２０８９号公報、特開平１１−３３６１０９号公報、特開平１１−２９３９１８号公報、特開平１１−２２９４１３号公報、特開平１１−５０４４５号公報、特開２００１−１５９１４６号公報、特開２００１−２００５４８号公報、特開２００１−２４１０５４号がある。
【０００５】
【発明が解決しようとする課題】
然しながら、従来の防水方法では、以下のような問題があった。
【０００６】
（１）漏水を防止するため、各芯材のフランジへの鋼板の溶接は、全長に亘ってかつ確実に行う必要があり、施工に時間が掛かる。
【０００７】
（２）ソイルセメントまたは泥水中への芯材の落とし込みの精度が十分に確保できないため、隣り合う芯材のフランジ面が必ずしも平行になっておらず、捩れ等が生じている。したがって、隣り合う芯材のフランジへの鋼板の取り付け及び溶接が困難である。
【０００８】
（３）連続壁の前面への防水シートの貼り付けは、漏水のない芯材のフランジ面も覆うこととなるため、経済性を損なうこととなる。
【０００９】
本発明は上記のような欠点を除くようにしたものである。
【００１０】
【課題を解決するための手段】

本発明の連続壁の防水方法は、少なくともその前端部にフランジを有し、このフランジの両側に夫々受け部を有する芯材を複数隣接して埋め込んで連続壁を構築する工程と、上記連続壁に埋め込まれた芯材の前端部が露出するまで地下を掘削する工程と、防水部材の両端を夫々上記受け部に挿入する工程と、上記受け部に弾性体をはめ込み、上記防水部材を上記芯材に固定する工程とよりなることを特徴とする。
【００１７】
【発明の実施の形態】
以下図面によって本発明の実施例を説明する。
【００１８】
本発明の連続壁の防水装置においては、図１に示すように、Ｈ形鋼の芯材２の前端部側フランジ３の両側裏側に、夫々側方外方に伸びその端部を直角に外方に折り曲げたＬ字状の受け材６を予め溶接等で固着し、上記フランジ３の芯材２の両側部より外側に受け部７を構成せしめた後、この芯材２をソイルセメントまたは泥水中に埋め込んで連続壁１を構成し、図２に示すように、上記連続壁１に埋め込まれた芯材２の前端部が露出するまで地下（点線部分）を掘削し、図３に示すように、その両端に夫々折れ曲がり部８を有する鋼板などの防水板９の上記折れ曲がり部８を夫々上記隣り合う芯材２の受け部７に挿入し、上記前端部側フランジ３の両側部と上記防水板９の折れ曲がり部８との間に夫々ゴム等の弾性体１０をはめ込み、止水せしめる。
【００１９】
なお、上記弾性体１０を水膨張性のものとすれば、水を含んでいない状態で上記部分にはめ込み、その後に弾性体１０に水を供給すれば、より強固に上記防水板９を上記フランジ３に固定せしめることができ、また作業時間の短縮を図ることができる。
【００２０】
また、図４に示すように、上記受け材６のＬ字部の折り曲げ角度と上記防水板９の折れ曲がり部８の折り曲げ角度を夫々９０度以上とし、この部分が互いに重なり合って上記防水板９が上記受け部７から外方に外れないようにするのが好ましい。なお、この実施例においては上記防水板９は上記受け部７の上方からこれに挿入せしめる。
【００２１】
図５は本発明の連続壁の防水装置の他の実施例を示し、この実施例においては防水板９を用いる代わりに、複数の隣り合う芯材２の離間距離に対応する長さの防水シート１１を用い、上記防水シート１１の両端部を夫々上記受け部７に挿入した状態で、上記受け部７に上記防水シート１１の外側から弾性体１０をはめ込み、止水せしめる。
【００２２】
なお、図６に示すように、受け材６のＬ字部の折り曲げ角度を９０度以上とし、受け部７から弾性体１０を外れにくくするのが好ましい。
【００２３】
また、上記受け材６を上記フランジ３面より前方に突出しないようにすれば、芯材２の前端部を露出するまで掘削する際、掘削機のバケットが受け材６に引っ掛かることなく掘削がスムーズに行えるとともに、フランジ面に付着した異物等を掘削機で容易に除去することができる。
【００２４】
図７は本発明の更に他の実施例を示し、この実施例においては、上記Ｌ字状の受け材６を用いる代わりに、上記芯材２の前端部側フランジの両側端部に夫々コ字状の受け材１２を固定し、上記この受け材１２によって受け部７を構成せしめる。
【００２５】
なお、この場合も図８に示すように、上記受け材１２を上記フランジ３面より前方に突出しないようにすれば、芯材２の前端部が露出するまで掘削する際、掘削機のバケットが引っ掛かることなく掘削がスムーズに行えるとともに、フランジ面に付着した異物等を掘削機で容易に除去することができる。
【００２６】
また、図９に示すように、上記コ字状の受け材１２の代わりに、Ｃ形状の溝からなる受け材１３を用いたり、図１０及び図１１に示すように、上記受け材１２及び１３の開口部を狭くし、上記受け部７から弾性体１０を外れにくくしてもよい。
【００２７】
また、図１２及び図１３に示すように、上記受け材１２及び１３の開口部を夫々フランジ３の側面外方に向くように上記フランジの両側端部に設けてもよい。
【００２８】
【発明の効果】
本発明の連続壁の防水装置及び防水方法によれば、ソイルセメントまたは泥水中への芯材の落とし込みの精度が十分に確保できず芯材に捩れがあっても、また固化したソイルセメントまたは泥水が十分に削り落とされずフランジ面より突出している場合でも、鋼板や防水シート等の防水部材を弾性体で固定するようにしたため、多少の設置誤差に関わらず止水することができる大きな利益がある。
【００２９】
また、防水シートをソイルセメントまたは泥水部のみに設置することにより、防水シートの量を低減することができ、また、フランジ面に固定物がある場合でも防水シートを固定することができる。
【００３０】
また、従来のように防水シートとなる鋼板を溶接せずに、弾性体を嵌め込むことにより鋼板を固定できるからその設置作業を短縮することができる。
【００３１】
また、受け材のＬ字部の角度や鋼材の両端の折り曲げ部の角度を９０度以上にしたり、受け部の開口部を狭めることにより、より弾性体を外れにくくすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a waterproofing device and a waterproofing method for a continuous wall, and more particularly to a waterproofing device and a waterproofing method for a continuous wall in which a core material such as an H-beam or an I-beam is embedded.
[0002]
[Prior art]
Soil cement column walls or mud solidified walls (hereinafter referred to as continuous walls) are constructed as temporary retaining walls or water blocking walls, into which H-shaped steel or I-shaped steel is embedded as a core material. This continuous wall is constructed underground before excavating the underground of the structure, and the excavation after that exposes the front end of the core material of the continuous wall to construct an underground space.
[0003]
The core material embedded in the continuous wall was generally buried and killed in the ground after the construction of the underground outer wall, which is the main structure, but in recent years, the core material has been partially removed from the main structure. In order to use it effectively, a synthetic wall construction method in which stud bolts are cast on the flange surface of the core material and integrated with the outer wall is used, but for the above stud bolts, a waterproof sheet is attached to the entire continuous wall It cannot be waterproof. For this reason, waterproofing at the front end of the core of the continuous wall is conventionally performed by using a flange at the front end of each adjacent H-shaped steel core 2 embedded in the continuous wall 1 as shown in FIGS. The steel sheet 4 is welded between the three, or the waterproof sheet 5 is stuck on the entire front end of the core material 2 as shown in FIG.
[0004]
In addition, as a well-known example, JP-A-5-222741, JP-A-8-296247, JP-A-7-90875, JP-A-9-242089, JP-A-11-336109, JP-A-11-293918. JP-A-11-229413, JP-A-11-50445, JP-A-2001-159146, JP-A-2001-200458, and JP-A-2001-241504.
[0005]
[Problems to be solved by the invention]
However, the conventional waterproofing method has the following problems.
[0006]
(1) In order to prevent water leakage, welding of the steel plate to the flange of each core material must be performed over the entire length and reliably, and it takes a long time for construction.
[0007]
(2) Since the accuracy of dropping the core material into soil cement or muddy water cannot be sufficiently ensured, the flange surfaces of adjacent core materials are not always parallel, and twisting or the like occurs. Therefore, it is difficult to attach and weld the steel plate to the flanges of the adjacent core members.
[0008]
(3) Affixing the waterproof sheet to the front surface of the continuous wall also covers the flange surface of the core material that does not leak water, which impairs economic efficiency.
[0009]
The present invention has been made to eliminate the above disadvantages.
[0010]

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
In the waterproofing device for a continuous wall according to the present invention, as shown in FIG. 1, each of the H-shaped steel core members 2 extends laterally outward on both sides behind the front end side flange 3 of the H-shaped steel core member 2, and the ends thereof extend at right angles. The L-shaped receiving member 6 bent in the direction is fixed in advance by welding or the like, and the receiving portion 7 is formed outside the both sides of the core member 2 of the flange 3. Then, the core member 2 is removed with soil cement or muddy water. The underground (dotted line portion) was excavated until the front end of the core material 2 embedded in the continuous wall 1 was exposed as shown in FIG. Then, the bent portions 8 of the waterproof plate 9 such as a steel plate having bent portions 8 at both ends thereof are inserted into the receiving portions 7 of the adjacent core members 2 respectively, and both sides of the front end side flange 3 and the waterproof portions 9 are inserted. An elastic body 10 such as rubber is fitted between each of the bent portions 8 of the plate 9 to stop water. Mel.
[0019]
If the elastic body 10 is made of a water-swelling material, the elastic body 10 is fitted into the above-mentioned portion without containing water, and then water is supplied to the elastic body 10 so that the waterproof plate 9 is more firmly attached to the flange. 3 can be fixed, and the working time can be reduced.
[0020]
Further, as shown in FIG. 4, the bending angle of the L-shaped portion of the receiving member 6 and the bending angle of the bent portion 8 of the waterproof plate 9 are each set to 90 degrees or more, and these portions are overlapped with each other to form the waterproof plate 9. It is preferable not to come off from the receiving part 7 outward. In this embodiment, the waterproof plate 9 is inserted into the receiving portion 7 from above.
[0021]
FIG. 5 shows another embodiment of the waterproof device for a continuous wall according to the present invention. In this embodiment, instead of using the waterproof plate 9, a waterproof sheet having a length corresponding to the separation distance between a plurality of adjacent core members 2 is shown. 11, the elastic body 10 is fitted into the receiving portion 7 from the outside of the waterproof sheet 11 in a state where both ends of the waterproof sheet 11 are inserted into the receiving portions 7, respectively, and water is stopped.
[0022]
In addition, as shown in FIG. 6, it is preferable that the bending angle of the L-shaped portion of the receiving member 6 be 90 degrees or more, so that the elastic body 10 is hardly detached from the receiving portion 7.
[0023]
Further, if the receiving member 6 is prevented from protruding forward from the flange 3 surface, when excavating until the front end of the core member 2 is exposed, the excavator can be smoothly excavated without being caught by the receiving member 6. In addition, foreign substances and the like attached to the flange surface can be easily removed by the excavator.
[0024]
FIG. 7 shows still another embodiment of the present invention. In this embodiment, instead of using the above-mentioned L-shaped receiving member 6, a U-shape is provided on both side ends of the front end side flange of the core material 2 respectively. The receiving member 12 is fixed, and the receiving portion 7 is constituted by the receiving member 12.
[0025]
In this case, as shown in FIG. 8, if the receiving member 12 is prevented from protruding forward from the surface of the flange 3, when excavating until the front end of the core member 2 is exposed, the bucket of the excavator is Excavation can be performed smoothly without being caught, and foreign substances and the like attached to the flange surface can be easily removed by the excavator.
[0026]
Further, as shown in FIG. 9, instead of the U-shaped receiving member 12, a receiving member 13 formed of a C-shaped groove is used, or as shown in FIGS. 10 and 11, the receiving members 12 and 13 are used. May be narrowed to make it difficult for the elastic body 10 to come off from the receiving part 7.
[0027]
As shown in FIGS. 12 and 13, the openings of the receiving members 12 and 13 may be provided at both side ends of the flange 3 so as to face outward from the side surfaces of the flange 3, respectively.
[0028]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the waterproofing apparatus and waterproofing method of the continuous wall of this invention, even if the accuracy of drop of the core material into soil cement or muddy water cannot be sufficiently ensured and the core material is twisted, solidified soil cement or muddy water Even if it is not sufficiently scraped off and protrudes from the flange surface, the waterproof member such as a steel plate or a waterproof sheet is fixed with an elastic body, so there is a great advantage that water can be stopped regardless of some installation errors. .
[0029]
In addition, by installing the waterproof sheet only in the soil cement or muddy water portion, the amount of the waterproof sheet can be reduced, and the waterproof sheet can be fixed even when there is a fixed object on the flange surface.
[0030]
Further, since the steel sheet can be fixed by fitting the elastic body without welding the steel sheet to be the waterproof sheet as in the related art, the installation work can be shortened.
[0031]
Further, by making the angle of the L-shaped portion of the receiving material or the angle of the bent portion at both ends of the steel material 90 degrees or more, or narrowing the opening of the receiving portion, the elastic body can be made more difficult to come off.
