Description

本発明は、不透水性材料からなる板状またはシート状の複数の遮水材からなる遮水壁の継手部における確実な遮水性を確認および確保でき、かつ遮水壁設置後の運用の簡便な遮水壁、遮水壁の遮水状況管理システムおよび遮水壁の遮水状況管理方法に関するものである。 The present invention is capable of confirming and ensuring reliable water shielding at a joint portion of a water shielding wall made of a plurality of plate-like or sheet- like water shielding materials made of a water-impermeable material, and simple operation after installation of the water-impervious wall. The present invention relates to a water shielding wall, a water shielding situation management system for a water shielding wall, and a water shielding situation management method for a water shielding wall.

廃棄物処分場における汚染水の漏洩防止や港湾施設建設時における遮水等において鋼管矢板や遮水パネルが多く用いられている。特に、廃棄物処分場で遮水性護岸構造等に用いられる場合には、鋼管矢板、遮水パネル等の継手部を介して処分場から外部への汚染水の浸出を防止することが厳しく要求される。   Steel pipe sheet piles and water shielding panels are often used to prevent leakage of contaminated water at waste disposal sites and water shielding during construction of harbor facilities. In particular, when used in a water-proof revetment structure, etc. at a waste disposal site, it is strictly required to prevent leaching of contaminated water from the disposal site to the outside through joints such as steel pipe sheet piles and water shielding panels. The

そこで、継手部の遮水方法として、雄雌係合部内に、モルタルジャケットと呼ばれ、硬化前のモルタルが流出しない程度のメッシュからなり、表面に遮水剤料を固着した袋体を挿入したうえ、その袋体にモルタルまたはコンクリートを充填することで前記遮水材料が継手内面の鋼材と圧接して漏水経路を遮断する方法が提案されている（特許文献１を参照）。  Therefore, as a water shielding method for the joint part, a bag body called a mortar jacket, made of a mesh that does not flow out of the mortar before curing, is inserted into the male / female engaging part, and a bag body with a water shielding agent fixed on the surface is inserted. In addition, a method has been proposed in which the bag body is filled with mortar or concrete so that the water shielding material is pressed against the steel material on the inner surface of the joint to block the water leakage path (see Patent Document 1).

また、遮水壁の遮水管理方法として、鋼管矢板、遮水パネル等の継手部内にスリット付きモニタリング用井戸を挿入して設置し、継手部内とモニタリング用井戸との間をモルタル、アスファルト混合物等の遮水剤で充填して、モニタリング用井戸内の水位、水質、濃度のいずれか一つまたは複数を管理することで不透水性地層から護岸外部への汚染水の漏出の有無を検知する遮水壁構造が提案されている（特許文献２を参照）。  In addition, as a water shielding management method for the impermeable walls, a monitoring well with a slit is inserted and installed in a joint part such as a steel pipe sheet pile, a water shielding panel, etc., and mortar, asphalt mixture, etc. between the joint part and the monitoring well Shielding to detect the leakage of contaminated water from the impervious formation to the outside of the revetment by managing one or more of the water level, water quality and concentration in the monitoring well. A water wall structure has been proposed (see Patent Document 2).

さらに、遮水壁の遮水管理方法として、内壁と外壁とで挟まれた中空部分を有する二重構造を備えた仕切り壁を設置し、内壁の破損等により処分場内部の汚染水が漏出しても周囲の地盤に流出拡散することなく、内壁と外壁との間の中空部分に滞留させ、滞留水の水質を管理することで処分場内部から中空部分への汚染水の漏出の有無を検知する遮水壁構造が提案されている（特許文献３を参照）。

A water shielding wall structure has been proposed (see Patent Document 3).

従来提案されてきた継手部の遮水方法は、鋼管矢板、遮水パネル等の建て込み中に雄雌係合部内に土砂が詰まるために、モルタル等の充填前に土砂を洗浄除去していた。この雄雌係合部内の洗浄作業は面倒で、かつ深い深度でのエアーリフトの効率低下により、洗浄が十分に出来ずにモルタル等を充填した袋体が着底せず、遮水性が十分に得られないという問題点があった。  The conventionally proposed water shielding method for joints has been to remove dirt and sand before filling with mortar and the like because the earth and sand are clogged in the male and female engaging parts during the construction of steel pipe sheet piles, water shielding panels, etc. . Cleaning work inside this male / female engaging part is cumbersome, and due to the reduced efficiency of the air lift at a deep depth, the bag body filled with mortar cannot be sufficiently cleaned and the water barrier is sufficient. There was a problem that it could not be obtained.

そして、遮水剤の充填直後の継手部が多少の水を通したとしても、時間の経過に伴い、水の流れとともに雄雌係合部内に土粒子等が詰まり遮水性が向上していくものであるが、これを確認する方法が無いという問題点があった。  And even if the joint part immediately after filling with the water shielding agent passes some water, with the passage of time, soil particles etc. are clogged in the male and female engaging part with the flow of water and the water shielding property will improve. However, there is a problem that there is no way to confirm this.

したがって、これらの場合においては、鋼管矢板、遮水パネル等の背面の地盤中に薬液を注入することで遮水性を確保することが必須であり、この補助工法の付加によりコストが増加するという問題点があった。  Therefore, in these cases, it is essential to ensure water shielding by injecting chemicals into the ground on the back of steel pipe sheet piles, water shielding panels, etc., and the problem of increased costs due to the addition of this auxiliary method There was a point.

また、雄雌係合部内の遮水効果箇所は雌継手のスリットと雄継手を係合させた部分のみであり、雄雌係合部内のほとんどの遮水剤は遮水の効果を果たさず、材料の無駄が生じるという問題点があった。  Moreover, the water-blocking effect location in the male-female engaging portion is only the portion where the female joint slit and the male joint are engaged, and most of the water-blocking agent in the male-female engaging portion does not perform the water-blocking effect, There was a problem that waste of materials occurred.

そして、スリット付モニタリング用井戸を継手部内に設置する場合においては、スリットの作成やモニタリング用井戸の挿入といった煩雑な手間が生じること、挿入時にモニタリング用井戸が破損する可能性があること、挿入後、モニタリング中に土粒子等がスリットを詰まらせる可能性があることといった問題点があった。  And, when installing a monitoring well with a slit in the joint, troublesome work such as creating a slit or inserting a monitoring well may occur, the monitoring well may be damaged at the time of insertion, There was a problem that soil particles could clog the slit during monitoring.

また、継手部に使用した遮水剤の欠陥等による漏水がスリット付モニタリング用井戸を通過しない場合においては本手法では漏水を検知できないという問題点があった。  In addition, in the case where water leakage due to a defect in the water shielding agent used in the joint portion does not pass through the monitoring well with slits, there is a problem in that this method cannot detect water leakage.

さらに、内壁と外壁とで挟まれた中空部分を有する二重構造を備えた仕切り壁を設置する場合においては、二重壁の製造コストが高いこと、建て込みに時間がかかり施工性が悪いことといった問題点があった。  Furthermore, when installing a partition wall with a double structure with a hollow part sandwiched between the inner wall and the outer wall, the manufacturing cost of the double wall is high, and it takes time to build and the workability is poor. There was a problem.

以下、この発明の好ましい実施例について図面を用いて詳細に説明する。  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

図１は、本発明の第一実施例に係る廃棄物処分場の保有水を遮水する遮水壁の設置状況を示す図である。
廃棄物処分場１００とその周囲地盤１０１との間の遮水壁として、例えば、遮水パネル１０２の列が不透水性地層１０３に至る深さまで打設されている。不透水性地層１０３の上には、透水性地層１０４が存在する。この遮水壁として用いられる遮水パネル１０２の配置方法を次に示す。 FIG. 1 is a diagram showing a state of installation of a water shielding wall that shields water retained in a waste disposal site according to the first embodiment of the present invention.
As a water-impervious wall between the waste disposal site 100 and the surrounding ground 101, for example, a row of water-impervious panels 102 is driven to a depth reaching the impermeable formation 103. On the impermeable formation 103, there is a water permeable formation 104. A method for arranging the water shielding panel 102 used as the water shielding wall will be described below.

図２は、本発明の第一実施例に係る廃棄物処分場の遮水壁における遮水パネルの設置状況を示す平面図である。
遮水パネル１０２は、パネル本体１０２ａと、その一方の側端部に設けられた雄継手１０２ｂと、他の側端部に設けられた断面円形状にしてその端部にスリットを有する雌継手１０２ｃとを備えてなり、隣接する遮水パネル１０２の雄継手１０２ｂと雌継手１０２ｃとが係合されることのみによって雄雌係合空洞部１０５を構築する。この雄雌係合空洞部１０５の遮水方法を次に示す。 FIG. 2 is a plan view showing an installation state of a water shielding panel on a water shielding wall of the waste disposal site according to the first embodiment of the present invention.
The water-impervious panel 102 includes a panel main body 102a, a male joint 102b provided at one side end portion thereof, and a female joint 102c having a circular cross section provided at the other side end portion and having a slit at the end portion thereof. The male / female engagement cavity 105 is constructed only by engaging the male joint 102b and the female joint 102c of the adjacent water shielding panels 102. The water shielding method for the male / female engagement cavity 105 will be described below.

図３は、図２の雄雌係合空洞部の拡大図である。遮水パネル１０２の雌継手１０２ｃのスリットＳ周辺と遮水パネル１０２と隣接する他の遮水パネル３００の雄継手３００ｂとの間のみに水膨潤性および所定の硬化遅延性を有する接着剤等の遮水剤３０１を塗布、または充填することによって、雄雌係合空洞部１０５の漏水経路をすべて遮断し、雄雌係合空洞部１０５内に雄継手３００ｂの背面側に形成される空洞部を形成し、液体が貯留可能な貯留部３０２とする。なお、遮水剤３０１は遮水性能を有するものであれば粘土、粘土モルタル、モルタル、アスファルト、コンクリート等のいずれかを選択して使用することができる。  FIG. 3 is an enlarged view of the male-female engagement cavity of FIG. An adhesive having water swellability and a predetermined curing delay property is provided only between the periphery of the slit S of the female joint 102c of the water shielding panel 102 and the male joint 300b of another water shielding panel 300 adjacent to the water shielding panel 102. By applying or filling the water shielding agent 301, all the water leakage paths of the male and female engaging cavities 105 are blocked, and a cavity formed on the back side of the male joint 300 b is formed in the male and female engaging cavities 105. The storage portion 302 is formed and can store liquid. Note that the water shielding agent 301 can be selected from clay, clay mortar, mortar, asphalt, concrete, or the like as long as it has water shielding performance.

このように、雄雌係合空洞部１０５は、隣接する遮水パネル１０２の雄継手１０２ｂと雌継手１０２ｃとが係合されることによってはじめて形成され、雄雌継手３００ａ，ｂ間に存する遮水剤３０１により継手部の遮水性を確保しつつ、仮に廃棄物処分場側内の汚染水が周辺地盤側へ流出する場合は当該継手部からの漏水に限られ、しかもその漏水は必ず貯留部３０２を通るといった機能を有する遮水壁を構築する。 Thus, male and female engagement cavity 105, the first formed by a male joint 102b and female joint 102c of seepage control panel 102 adjacent are engaged, water barrier that exists male and female couplings 300a, between b In the case where the contaminated water in the waste disposal site flows out to the surrounding ground side while ensuring the water shielding property of the joint portion by the agent 301, the leakage is limited to the leak from the joint portion, and the water leak is always stored in the storage portion 302. Build a water-impervious wall with the function of passing through.

なお、貯留部３０２を構成する雄雌係合空洞部１０５は、前記遮水剤３０１を雌継手１０２ｃの全断面に膨潤・充填されるよう塗布等により設け、雄雌継手１０２ｂ，ｃを係合した後、遮水剤３０１が硬化してからその一部を洗堀することにより、遮水性を確保した状態で空洞部を形成することもできる。 Incidentally, the male and female engagement cavity 105 which constitutes the reservoir 302, the provided by coating or the like so that the seepage control agent 301 is swelling and filling the entire cross-section of the female joint 102c, engaging the male and female joint 102b, the c Then, after the water-blocking agent 301 is cured, a part of the water-blocking agent 301 is scoured, so that the cavity can be formed in a state where the water-blocking property is secured.

少量の遮水剤で確実に遮水するためには遮水パネルの建て込み時に継手部分に土や砂利等の異物を入れないことが必要である。そこで、遮水パネルの継手部内に異物が入るのを防ぐため、例えば雌継手１０２ｃの底部に蓋を取り付けておくことが望ましい。また、次のような保護部材を使用することもできる。  In order to ensure water shielding with a small amount of water shielding agent, it is necessary to prevent foreign matter such as soil and gravel from entering the joint when the water shielding panel is installed. Therefore, in order to prevent foreign matter from entering the joint portion of the water shielding panel, it is desirable to attach a lid to the bottom portion of the female joint 102c, for example. Moreover, the following protective members can also be used.

The bottom protection member 400 includes a cylindrical operation pipe 401, a center bar 402 inserted into the operation pipe 401, one end connected to the lower end 403 a of the center bar 402, and the other end 403 b via the steel frame 404. A plurality of iron plates 403 connected to 401 overlap and form a tip 405 that can be expanded and contracted by moving the operation pipe 401 up and down with respect to the center bar 402. The bottom protection member 400 is attached to the bottom of the female joint 102c in a diameter-enlarged state and is built in the ground. After the adjacent water shielding panel 300 is installed, the bottom protection member 400 is reduced in diameter by reducing the tip 405. Can be recovered.

ここで、あるモニタリング用井戸５００から遮水壁継手部の水途を通って水が外に漏れた場合等、モニタリング用井戸５００の水位が所定水位より絶対的に低下するおそれがあるが、この場合においては、コンピュータ５１４からの指示により水位低下量を管理用モニタ５１３に表示させ、送水ポンプ５０４を作動して送水を開始すると同時に、流向切替バルブ５０５、およびバルブ５０８の送水のための流路を開き、このモニタリング用井戸５００に注水することにより、廃棄物貯層部５０１の汚染水を遮水壁の系外に拡散されるのを防止することができる。注水中は流量計５０７ａにより注入量と、水位計５０２ａにより水位が同時に管理されており、適宜必要量のみを注水できる。  Here, when water leaks outside from a certain monitoring well 500 through the waterway of the impermeable wall joint portion, the water level of the monitoring well 500 may be absolutely lower than the predetermined water level. In some cases, the amount of water level decrease is displayed on the management monitor 513 in accordance with an instruction from the computer 514, and the water supply pump 504 is activated to start water supply. At the same time, the flow direction switching valve 505 and the flow path for water supply of the valve 508 are used. By opening and injecting water into the monitoring well 500, it is possible to prevent the contaminated water in the waste reservoir 501 from being diffused outside the impermeable wall system. In the water injection, the injection amount is controlled simultaneously by the flow meter 507a and the water level is controlled simultaneously by the water level meter 502a, and only a necessary amount can be injected as appropriate.

さらに、モニタリング用井戸５００の水位と廃棄物貯層部５０１の水位をそれぞれ水位計５０２ａ、５０２ｂにて検知して、モニタリング用井戸５００の水位が廃棄物貯層部５０１の水位より相対的に低下した場合においては、コンピュータ５１４が両水位を管理用モニタ５１３に表示させ、水位検出結果を比較すると同時に、モニタリング用井戸５００に注水するか、もしくは廃棄物貯層部内５０１の保有水を排水するか、またはモニタリング用井戸５００内の水を排水することによって廃棄物貯層部５０１の保有水を排水するかを自動的に選択して実施することができる。廃棄物貯層部５０１の汚染水が、遮水壁継手部の水途を通ってモニタリング用井戸５００内に浸入している場合、モニタリング用井戸５００内の水を排水することにより、当該水途を介して廃棄物貯層部５０１の保有水を排水することができる。  Further, the water level of the monitoring well 500 and the water level of the waste reservoir 501 are detected by the water level gauges 502a and 502b, respectively, and the water level of the monitoring well 500 is relatively lower than the water level of the waste reservoir 501. In this case, whether the computer 514 displays both water levels on the management monitor 513 and compares the water level detection results, and at the same time, water is poured into the monitoring well 500 or the retained water in the waste reservoir 501 is drained. Alternatively, by draining the water in the monitoring well 500, it is possible to automatically select whether or not to drain the water retained in the waste reservoir 501. When the contaminated water in the waste reservoir 501 has entered the monitoring well 500 through the waterway of the impermeable wall joint, the water in the monitoring well 500 is drained, thereby The water retained in the waste reservoir 501 can be drained via the.

また、例えば、モニタリング用井戸５００の水位よりも廃棄物貯層部５０１の水位が高くなると、廃棄物貯層部５０１内の汚染水が周囲地盤１０１側に流出し、またモニタリング用井戸５００の水位が廃棄物貯層部５０１の水位よりも高すぎると、モニタリング用井戸５００内の水が廃棄物貯層部５０１に流入する。   For example, when the water level of the waste reservoir 501 becomes higher than the water level of the monitoring well 500, the contaminated water in the waste reservoir 501 flows out to the surrounding ground 101 side, and the water level of the monitoring well 500 If the water level of the waste reservoir 501 is too high, the water in the monitoring well 500 flows into the waste reservoir 501.

そこで、モニタリング用井戸５００の水位を廃棄物貯層部５０１の水位よりもやや高くして、廃棄物貯層部５０１内に流入する水の量が少なくなるように管理する。   Therefore, the water level of the monitoring well 500 is set slightly higher than the water level of the waste reservoir 501 so that the amount of water flowing into the waste reservoir 501 is reduced.

さらに、モニタリング用井戸５００の水位を廃棄物貯層部５０１の水位より低くすることによって、廃棄物貯層部５０１の保有水を流入させて排水ポンプ等の排水手段を用いて排水する方法もある。   Further, there is a method in which the water level of the monitoring well 500 is made lower than the water level of the waste reservoir unit 501 so that the water held in the waste reservoir unit 501 flows and drains using drainage means such as a drainage pump. .

したがって、これらの機能を有することにより、保有水の管理を確実に実施することができ、また、漏水しているモニタリング用井戸を簡単に特定でき、補修等の対応策も早期に可能となる。   Therefore, by having these functions, it is possible to reliably manage the retained water, to easily identify the monitoring well that is leaking water, and to enable countermeasures such as repair at an early stage.

本発明における貯留部３０２を遮水材の継手部に構成するためには継手の接続に使用される遮水剤が少量であっても、確実に遮水性を保持する必要がある。そこで、より確実に遮水性を保持するために遮水パネルの側端部付近の形状を改良した実施例を次に示す。  In order to configure the reservoir 302 in the present invention as a joint portion of a water shielding material, it is necessary to reliably maintain the water shielding property even if the amount of the water shielding agent used to connect the joint is small. Therefore, an embodiment in which the shape in the vicinity of the side end portion of the water shielding panel is improved in order to more reliably maintain the water shielding property will be described below.

図６は、本発明の第二実施例に係る遮水性を管理する遮水壁の遮水管理方法を示す、（ａ）ストッパー付雄継手使用時における雄雌係合空洞部の拡大図、（ｂ）角形雌継手使用時における雄雌係合空洞部の拡大図、（ｃ）ストッパー付雄継手および角形雌継手使用時における雄雌係合空洞部の拡大図、（ｄ）パイプ・イン・パイプ形式の雄雌継手使用時における雄雌係合空洞部の拡大図である。 FIG. 6 shows a water shielding management method for a water shielding wall for managing water shielding according to a second embodiment of the present invention, (a) an enlarged view of a male-female engagement cavity when using a male joint with a stopper, b) Enlarged view of male and female engaging cavities when using square female joint, (c) Enlarged view of male and female engaging cavities when using male joint with stopper and square female joint, (d) Pipe-in-pipe is an enlarged view of the male and female engagement cavity when the male and female joint use format.

The use of the stopper 600d for preventing entry into the female joint 102c and the stopper 600e for preventing escape from the female joint 102c makes the formation of the water storage portion 602 simple and reliable, and further reduces the amount of the water shielding material. It becomes possible to.

また、図６（ｂ）に示すように、遮水パネル６１０が、パネル本体１０２ａと、雄継手１０２ｂと、角形状の雌継手６１０ｃとを備え、雄継手１０２ｂと雌継手６１０ｃとの組合せからなる雄雌係合空洞部６１１の貯水部６１２を構築する。  Further, as shown in FIG. 6B, the water shielding panel 610 includes a panel main body 102a, a male joint 102b, and a rectangular female joint 610c, and is formed of a combination of the male joint 102b and the female joint 610c.

そして、図６（ｄ）に示すパイプ・イン・パイプ形式のものは、一方の遮水パネル６３０が、パネル本体１０２と、円形状の雌継手１０２ｃとを備えることは図６（ａ）と同様であるが、他方の遮水パネル６３０の雄継手１０２ｂが円形状となっている。雄継手１０２ｂは、その左右両側部にそれぞれ一対の丸綱６４０が溶接等により固定され、一対の丸綱６４０巻に前記遮水剤３０１が固定されている（膨潤後は、一点鎖線で図示する形態となり、雄雌継手間の遮水性を確保する）。また、雄継手１０２ｂの先端にはスリットＳが形成されている。 In the pipe-in-pipe type shown in FIG. 6D, one of the water-impervious panels 630 includes the panel body 102 and the circular female joint 102c, as in FIG. 6A. However, the male joint 102b of the other water-impervious panel 630 has a circular shape. The male joint 102b has a pair of round ropes 640 fixed to the left and right sides of the male joint 102b by welding or the like, and the water shielding agent 301 is fixed to a pair of round ropes 640 (after the swelling, it is indicated by a one-dot chain line). Form and ensure water barrier between male and female joints). A slit S is formed at the tip of the male joint 102b.

上述した遮水パネルを地盤に埋設する方法以外に、遮水性に優れた地中連続壁であるソイルセメント壁内に埋設する方法がある。そこで、遮水パネルをソイルセメント壁内に埋設する場合の実施例を次に示す。  In addition to the above-described method of embedding the water-impervious panel in the ground, there is a method of embedding it in a soil cement wall that is an underground continuous wall excellent in water-imperviousness. Therefore, an embodiment in the case where the water shielding panel is embedded in the soil cement wall will be described below.

図７は、本発明の第三実施例に係るソイルセメント壁内に埋設する遮水パネルを連結して形成される遮水壁の設置状況を示す、（ａ）遮水剤不使用状態における遮水壁の貯水部の拡大図、（ｂ）遮水剤使用状態における遮水壁の貯水部の拡大図である。  FIG. 7 shows the installation situation of the water shielding wall formed by connecting the water shielding panels embedded in the soil cement wall according to the third embodiment of the present invention. It is an enlarged view of the water storage part of a water wall, (b) It is an enlarged view of the water storage part of the water shielding wall in the state of using a water shielding agent.

図７（ａ）に示すとおり、まず、遮水パネル１０２を未固結状態のソイルセメント壁７００内に建て込み、遮水パネル１０２の雌継手１０２ｃと遮水パネル１０２と隣接する他の遮水パネル３００の雄継手３００ｂの接続には遮水剤を使用せずに、雌継手１０２ｃと雄継手３００ｂが係合するように遮水パネル３００を建て込む。  As shown in FIG. 7A, first, the impermeable panel 102 is built in an unconsolidated soil cement wall 700, and the female joint 102c of the impermeable panel 102 and another impermeable water adjacent to the impermeable panel 102 are assembled. For the connection of the male joint 300b of the panel 300, the water shielding panel 300 is built so that the female joint 102c and the male joint 300b are engaged without using a water shielding agent.

そして、遮水パネルを連結して作成された遮水壁をソイルセメント壁７００で挟み込むサンドイッチ構造とし、雄雌係合空洞部１０５を作成するために雄雌係合部内のソイルセメントを除去する。ソイルセメントの除去は、例えばウォータージェット、ブラシ等によって実施される。  Then, the water shielding wall formed by connecting the water shielding panels is sandwiched between the soil cement walls 700, and the soil cement in the male and female engaging portions is removed to form the male and female engaging cavities 105. The removal of the soil cement is performed, for example, with a water jet, a brush or the like.

遮水パネル１０２の雌継手１０２ｃと遮水パネル３００の雄継手３００ｂが係合されて初めて形成される雄雌係合空洞部１０５は、不透水性のソイルセメント壁７００により挟み込まれ遮水性能が保持されているために遮水剤を使用せずとも液体を貯留可能な貯留部７０１を備えた遮水壁が構築される。  The male-female engagement cavity 105 formed only after the female joint 102c of the water-impervious panel 102 and the male joint 300b of the water-impervious panel 300 are engaged with each other is sandwiched by the impervious soil cement wall 700 and has a water-blocking performance. Since the liquid is retained, a water-impervious wall including a reservoir 701 that can store liquid without using a water-impermeable agent is constructed.

さらに、地震等によりソイルセメント壁の損傷が懸念される場合においては、図７（ｂ）に示すとおり、第一実施例と同様に、雌継手１０２ｃのスリットＳ周辺と雄継手３００ｂとの間のみに水膨潤性および所定の硬化遅延性を有する接着剤等の遮水剤３０１を塗布、または充填することによってのみ形成される雄雌係合空洞部１０５の漏水経路をすべて遮断しつつ、雄雌係合空洞部１０５内に雄継手３００ｂの背面側に形成される空洞部が貯留部となる。  Furthermore, when there is a concern about damage to the soil cement wall due to an earthquake or the like, as shown in FIG. 7B, as in the first embodiment, only between the periphery of the slit S of the female joint 102c and the male joint 300b. Male and female while blocking all the water leakage paths of the male-female engagement cavity 105 formed only by applying or filling a water-blocking agent 301 such as an adhesive having water swellability and a predetermined retarding property to A cavity formed on the back side of the male joint 300b in the engagement cavity 105 serves as a reservoir.

遮水壁をソイルセメント壁７００内に埋設し、かつ遮水剤３０１を使用する場合の遮水壁の建て込み方法を下記に２種類示す。   The following two types of methods for installing the impermeable wall when the impermeable wall is embedded in the soil cement wall 700 and the impermeable agent 301 is used.

第一の方法は、まず、遮水パネル１０２をソイルセメント壁７００中に建て込み、遮水パネル１０２の雌継手１０２ｃ内のソイルセメントを除去する。
そして、雌継手１０２ｃのスリットＳ周辺と雄継手３００ｂとの間のみに遮水剤３０１を塗布して、隣接する他の遮水パネル３００を建て込んで初めて雄雌係合空洞部１０５を形成させる。
したがって、雄雌係合空洞部１０５内の雄継手３００ｂの背面側に形成される空洞部が貯留部７０１を構築する。 In the first method, first, the water shielding panel 102 is installed in the soil cement wall 700, and the soil cement in the female joint 102c of the water shielding panel 102 is removed.
Then, the male-female engagement cavity 105 is formed only after the water-blocking agent 301 is applied only between the periphery of the slit S of the female joint 102c and the male joint 300b and the other adjacent water-shielding panel 300 is installed. .
Therefore, the cavity part formed in the back side of the male joint 300b in the male-female engagement cavity part 105 constructs the storage part 701.

第二の方法は、地上にて、遮水パネル１０２の雌継手１０２ｃのスリットＳ周辺と隣接する他の遮水パネル３００の雄継手３００ｂとの間のみに遮水剤３０１を塗布して、遮水パネル１０２と遮水パネル３００を連結して初めて雄雌係合空洞部１０５を形成させる。
そして、連結した遮水パネルをソイルセメント壁７００中に建て込み、雄雌係合空洞部１０５内のソイルセメントを除去することにより、雄雌係合空洞部１０５が貯留部７０１を構築する。 In the second method, on the ground, a water shielding agent 301 is applied only between the periphery of the slit S of the female joint 102c of the water shielding panel 102 and the male joint 300b of the other water shielding panel 300 adjacent thereto. The male-female engagement cavity 105 is formed only after the water panel 102 and the water-impervious panel 300 are connected.
And the male-female engagement cavity part 105 constructs | stores the storage part 701 by installing the connected water-impervious panel in the soil cement wall 700, and removing the soil cement in the male-female engagement cavity part 105.

また、第二実施例で説明した継手形状を有する遮水パネルを使用しても貯留部７０１を構築することが可能である。
さらに、貯留部７０１は第一実施例と同様にモニタリング用井戸５００として使用が可能である。 In addition, the reservoir 701 can be constructed even if the water shielding panel having the joint shape described in the second embodiment is used.
Furthermore, the reservoir 701 can be used as the monitoring well 500 as in the first embodiment.
