Abstract

<P>PROBLEM TO BE SOLVED: To provide a storage warehouse under a ground capable of reducing ground vibrations with a simple constitution. <P>SOLUTION: A warehouse body 14 for storing gunpowder and the like, which is a main part of a storage warehouse 11, is provided on an excavation bottom surface 17 formed by excavating a ground 16. A surface above the excavation bottom surface 17, which is an outer surface of the warehouse body 14, is covered with a first soil stratum 21, and its outer surface is covered with a sheet body 13. A rubber impermeable sheet is used as the sheet body 13, and its entire outer surface is covered with a second soil stratum 27 whose top surface is aligned with the ground 16. The sheet body 13 has an impermeable property, and therefore, rain water and the like permeated from the outer surface through the second soil stratum do not permeate the first soil stratum 21. Thus, a moisture content of the first soil stratum 21 is always constant, and therefore there is no possibility of varying a propagating force of an explosion soil pressure, which is transmitted through the first soil stratum 21 and causes ground vibrations. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

この発明は貯蔵倉庫に関し、特に爆発性を有する火薬類等を貯蔵するための貯蔵倉庫に関するものである。   The present invention relates to a storage warehouse, and more particularly to a storage warehouse for storing explosive explosives and the like.

従来の火薬類等を貯蔵するための貯蔵倉庫は、地上にコンクリート製の構造体で構成されているのが一般的である。   Conventional storage warehouses for storing explosives and the like are generally composed of concrete structures on the ground.

又、特許文献１に示すように、一対の不透水性のシートの間に複数の密封式のチューブ群を配列して連続構造体を形成し、この連続構造体に発泡ウレタン等を充填して所定の形状に立ち上がらせて貯蔵倉庫を構築する方法が提案されている。これによって、施工が容易となり、トンネル内で大きな容積の倉庫を確保できるとされている。
特公平６−２３５１８号公報 Moreover, as shown in Patent Document 1, a plurality of sealed tube groups are arranged between a pair of impermeable sheets to form a continuous structure, and this continuous structure is filled with foamed urethane or the like. A method for building a storage warehouse by standing up in a predetermined shape has been proposed. This makes it easy to construct and secures a large-volume warehouse in the tunnel.
Japanese Patent Publication No. 6-23518

上記のような従来の地上におけるコンクリート製の構造体の貯蔵倉庫では、火薬類が爆発したとき、構造体の破片が飛散したり、爆風圧が拡散して周囲に影響を与える虞がある。   In the above-described conventional storage warehouse for concrete structures on the ground, when explosives explode, there is a risk that fragments of the structure will be scattered or the blast pressure will diffuse and affect the surroundings.

又、特許文献１の貯蔵倉庫では、コンクリート片の飛散等は無いものの構造が複雑であり、施工性、汎用性が高いとは言えない。   Moreover, in the storage warehouse of patent document 1, although there is no scattering of a concrete piece etc., the structure is complicated and it cannot be said that construction property and versatility are high.

そこで、貯蔵倉庫を地中に設置することが提案されている。この場合、地中爆発となるため、爆風圧等による周囲の影響を低減することができる。しかし、地中爆発は爆土圧により地盤振動を発生する。この爆土圧は倉庫周りの土層の水分含有量が多ければそれだけ大きくなり、結果として地盤振動も増大する。この水分含有量は雨水の影響を受けるため、倉庫に対する保安距離を大きくとらざるを得ない。   Therefore, it has been proposed to install a storage warehouse in the ground. In this case, since it is an underground explosion, the influence of the surroundings by a blast pressure etc. can be reduced. However, underground explosions generate ground vibrations due to explosive pressure. This explosive pressure increases as the moisture content of the soil layer around the warehouse increases, resulting in increased ground vibration. Since this moisture content is affected by rainwater, the security distance to the warehouse must be increased.

この発明は、上記のような課題を解決するためになされたもので、簡易な構成で地盤振動を低減できる地中における貯蔵倉庫を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide an underground storage warehouse that can reduce ground vibration with a simple configuration.

上記の目的を達成するために、請求項１記載の発明は、火薬類等を貯蔵するための貯蔵倉庫であって、地面を掘削した掘削底面上に設置され、火薬類等を貯蔵するための倉庫本体と、倉庫本体の外面を覆う第１土層と、第１土層の外面を覆う、遮水性を有するシート体と、シート体の側面と掘削側面との間に形成された第２土層とを備えたものである。   In order to achieve the above object, an invention according to claim 1 is a storage warehouse for storing explosives and the like, which is installed on a bottom surface excavated from the ground, for storing explosives and the like. A warehouse body, a first soil layer covering the outer surface of the warehouse body, a sheet body having water shielding properties covering the outer surface of the first soil layer, and a second soil formed between the side surface and the excavation side surface of the sheet body And a layer.

このように構成すると、第１土層への雨水等の浸入が阻止されると共に、シート体の側面は第２土層で囲まれる。   If comprised in this way, intrusion of rain water etc. to the 1st soil layer will be blocked, and the side of a sheet will be surrounded by the 2nd soil layer.

請求項２記載の発明は、火薬類等を貯蔵するための貯蔵倉庫であって、地面を掘削した掘削底面上に設置され、火薬類等を貯蔵するための倉庫本体と、倉庫本体の外面を覆う第１土層と、第１土層の上面において、少なくとも倉庫本体の平面視における範囲を覆うように平面状に設置された、遮水性を有するシート体とを備えたものである。   The invention according to claim 2 is a storage warehouse for storing explosives and the like, which is installed on a bottom surface excavated from the ground, and stores a warehouse main body for storing explosives and the like, and an outer surface of the warehouse main body. A first soil layer to be covered, and a sheet body having water shielding properties installed on the upper surface of the first soil layer so as to cover at least a range in a plan view of the warehouse body.

このように構成すると、倉庫本体の上方に位置する第１土層の部分への雨水等の浸入が阻止される。   If comprised in this way, permeation of rain water etc. to the part of the 1st soil layer located above a warehouse main part is prevented.

請求項３記載の発明は、請求項２記載の発明の構成において、シート体を覆うように第１土層の上に形成された第２土層を更に備えたものである。   The invention described in claim 3 is the configuration of the invention described in claim 2, further comprising a second soil layer formed on the first soil layer so as to cover the sheet body.

このように構成すると、シート体の上面は第２土層で覆われる。   If comprised in this way, the upper surface of a sheet | seat body will be covered with a 2nd soil layer.

請求項４記載の発明は、火薬類等を貯蔵するための貯蔵倉庫であって、地面を掘削した掘削底面上に設置され、火薬類等を貯蔵するための倉庫本体と、倉庫本体の外面を覆う第１土層と、第１土層の外面を覆う、遮水性を有するシート体と、シート体の外面を覆う第２土層とを備えたものである。   The invention according to claim 4 is a storage warehouse for storing explosives and the like, and is installed on a drilling bottom surface excavated from the ground, and has a warehouse main body for storing explosives and the like, and an outer surface of the warehouse main body. A first soil layer to cover, a sheet body having a water shielding property covering the outer surface of the first soil layer, and a second soil layer covering the outer surface of the sheet body.

このように構成すると、第１土層への雨水等の浸入が阻止されると共に、シート体の全面は第２土層で囲まれる。   If comprised in this way, intrusion of rain water etc. to the 1st soil layer will be blocked, and the whole surface of a sheet will be surrounded by the 2nd soil layer.

以上説明したように、請求項１記載の発明は、第１土層への雨水等の浸入が阻止されるので、第１土層の水分保有量が常に一定になる。そのため、爆発時の爆土圧が一定になり、周辺における保安距離の確保が容易となる。又、シート体の側面方向への拡がりが第２土層によって阻止されるので、シート体の倉庫本体に対する包囲効果が高まり、信頼性が向上する。   As described above, according to the first aspect of the present invention, since the entry of rainwater or the like into the first soil layer is prevented, the amount of water retained in the first soil layer is always constant. Therefore, the explosive earth pressure at the time of explosion becomes constant, and it is easy to secure a safety distance in the vicinity. Further, since the sheet body is prevented from spreading in the lateral direction by the second soil layer, the surrounding effect of the sheet body with respect to the warehouse main body is enhanced, and the reliability is improved.

請求項２記載の発明は、倉庫本体の上方に位置する第１土層の部分への雨水等の浸入が阻止されるので、その部分の水分保有量が常に一定になる。そのため、爆発時の地上方向への爆土圧が一定になり、周辺における保安距離の確保が容易となる。   According to the second aspect of the present invention, since the intrusion of rainwater or the like into the portion of the first soil layer located above the warehouse body is prevented, the amount of water held in that portion is always constant. For this reason, the earth pressure in the ground direction at the time of the explosion becomes constant, and it becomes easy to secure the safety distance in the vicinity.

請求項３記載の発明は、請求項２記載の発明の効果に加えて、シート体の上方向への浮き上がりが第２土層によって阻止されるので、シート体の倉庫本体に対する設置効果が高まり、信頼性が向上する。   In addition to the effect of the invention of claim 2, the invention of claim 3 prevents the sheet body from being lifted upward by the second soil layer, so the installation effect of the sheet body on the warehouse body is enhanced, Reliability is improved.

請求項４記載の発明は、第１土層への雨水等の浸入が阻止されるので、第１土層の水分保有量が常に一定になる。そのため、爆発時の爆土圧が一定になり、周辺における保安距離の確保が容易となる。又、シート体の浮き上がりが第２土層によって阻止されるので、シート体の倉庫本体に対する包囲効果が高まり、信頼性が向上する。   In the invention according to claim 4, since the intrusion of rainwater or the like into the first soil layer is prevented, the water content of the first soil layer is always constant. Therefore, the explosive earth pressure at the time of explosion becomes constant, and it is easy to secure a safety distance in the vicinity. Further, since the floating of the sheet body is prevented by the second soil layer, the surrounding effect of the sheet body with respect to the warehouse main body is enhanced, and the reliability is improved.

図１はこの発明の第１の実施の形態による貯蔵倉庫の外観形状を示す平面図であり、図２は図１で示したＩＩ−ＩＩラインの断面図である。   FIG. 1 is a plan view showing the appearance of a storage warehouse according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG.

これらの図を参照して、貯蔵倉庫１１の中心となる、火薬類等が貯蔵されている倉庫本体１４は、地面１６を掘削して形成された掘削底面１７の上に設置されている。倉庫本体１４は、その材質は限定しないが、以下に述べるようなその外面に設置する構造体等を保持できるような強度を有する構造であれば良い。   With reference to these drawings, a warehouse main body 14 storing explosives and the like, which is the center of the storage warehouse 11, is installed on an excavation bottom surface 17 formed by excavating the ground 16. The material of the warehouse body 14 is not limited, but may be any structure as long as it can hold a structure or the like installed on the outer surface as described below.

倉庫本体１４の外面であって掘削底面１７より上の面が第１土層２１で覆われており、その外面がシート体１３によって覆われている。第１土層２１の土の種類や施工厚さは倉庫本体１４内に貯蔵される火薬類の爆発力の大きさによって決定すれば良い。シート体１３は総ゴム製の遮水シートが用いられており、その地面側の端部となる平坦部１９ａ，１９ｂの各々は掘削底面１７の上に配置されているが、アンカーボルト等の固定手段で掘削底面１７に固定するようにしても良い。   The outer surface of the warehouse main body 14 and the surface above the excavation bottom surface 17 is covered with the first soil layer 21, and the outer surface is covered with the sheet body 13. What is necessary is just to determine the kind and construction thickness of the 1st soil layer 21 with the magnitude | size of the explosive force of the explosives stored in the warehouse main body 14. FIG. The sheet body 13 is made of a total rubber impermeable sheet, and each of the flat portions 19a and 19b serving as end portions on the ground side is disposed on the excavation bottom surface 17, but is fixed with an anchor bolt or the like. You may make it fix to the excavation bottom face 17 by a means.

シート体１３の外面の全面は、その上面が地面１６に整列した第２土層２７によって覆われている。これによって、掘削側面１８ａ，１８ｂを含め掘削部分の残りがすべて第２土層で埋められることになる。   The entire outer surface of the sheet body 13 is covered with a second soil layer 27 whose upper surface is aligned with the ground 16. As a result, the remainder of the excavation part including the excavation side surfaces 18a and 18b is filled with the second soil layer.

尚、倉庫本体１４の長手方向（図１における上下方向）の両端部は、図２の断面図と同様に第１土層２１、シート体１３及び第２土層２７で覆うように構成しても良いが、扉構造を組み込んだ他の構造体によって塞ぐようにしても良い。いずれにしても、図２における倉庫本体１４の側面方向及び上面方向は、第１土層２１、シート体１３及び第２土層２７でその全面が覆われることになる。   Both ends of the warehouse main body 14 in the longitudinal direction (vertical direction in FIG. 1) are configured to be covered with the first soil layer 21, the sheet body 13, and the second soil layer 27 as in the cross-sectional view of FIG. However, it may be closed by another structure incorporating a door structure. In any case, the entire surface of the warehouse main body 14 in FIG. 2 is covered with the first soil layer 21, the sheet body 13, and the second soil layer 27.

次に、この貯蔵倉庫１１における安全性について説明する。   Next, safety in the storage warehouse 11 will be described.

倉庫本体１４に収納されている火薬類がなんらかの原因で爆発すると、周囲にその破片が飛散したり爆風が拡散する。しかし、倉庫本体１４の掘削底面１７より上の周囲は第１土層２１で覆われているため、破片や爆風は第１土層２１で吸収されながらシート体１３に伝達する。尚、掘削底面１７の方向に拡散した爆風は掘削底面１７に吸収され、掘削底面１７より上の周囲に影響を与えることは無い。   When the explosives stored in the warehouse body 14 explode for some reason, the fragments are scattered around and the blast spreads. However, since the periphery of the warehouse main body 14 above the excavation bottom surface 17 is covered with the first soil layer 21, debris and blast are transmitted to the sheet body 13 while being absorbed by the first soil layer 21. The blast diffused in the direction of the excavation bottom surface 17 is absorbed by the excavation bottom surface 17 and does not affect the surroundings above the excavation bottom surface 17.

シート体１３は第１土層２１を覆っていると共に、その外面は第２土層２７で覆われているため、シート体１３は捲りあがることがない。その結果、倉庫本体１４を包囲したシート体１３に伝達された爆風等は外部に拡散されることがない。尚、第２土層２７の土の種類や施工厚さは、倉庫本体１４内に貯蔵される火薬類の爆発力によるシート体１３への影響に応じて決定すれば良い。   Since the sheet body 13 covers the first soil layer 21 and its outer surface is covered with the second soil layer 27, the sheet body 13 does not roll up. As a result, the blast transmitted to the sheet body 13 surrounding the warehouse body 14 is not diffused outside. The soil type and construction thickness of the second soil layer 27 may be determined according to the influence on the sheet body 13 due to the explosive force of explosives stored in the warehouse body 14.

尚、シート体１３は遮水性を有しているため、第２土層２７を介して外面から浸み込んだ雨水等が第１土層２１に浸透することは無い。そのため、第１土層２１が保有する水分量は常に一定となるので、第１土層２１を介して伝達し、地盤振動をもたらす爆土圧の伝播力が変動する虞が無い。したがって、火薬類の爆発による地盤振動の周囲への影響が一定化するので、貯蔵倉庫１１周りに必要な保安距離の確保が容易となる。又、シート体１３の遮水性により火薬類の湿潤を防ぐ効果も期待できる。   In addition, since the sheet body 13 has a water-impervious property, rainwater or the like soaked from the outer surface through the second soil layer 27 does not penetrate into the first soil layer 21. For this reason, since the amount of water held by the first soil layer 21 is always constant, there is no possibility that the propagation force of the earth pressure transmitted through the first soil layer 21 and causing ground vibration will fluctuate. Therefore, since the influence on the surroundings of the ground vibration due to the explosion of the explosives is made constant, it is easy to secure the necessary safety distance around the storage warehouse 11. In addition, an effect of preventing the explosives from being wet due to the water shielding property of the sheet body 13 can be expected.

図３はこの発明の第２の実施の形態による貯蔵倉庫の概略断面図であって、先の実施の形態による図２に対応した図である。   FIG. 3 is a schematic sectional view of a storage warehouse according to the second embodiment of the present invention and corresponds to FIG. 2 according to the previous embodiment.

図を参照して、基本的な構成は先の実施の形態の貯蔵倉庫と同一であるので、ここではその相違点について主に説明する。   Referring to the drawing, the basic configuration is the same as that of the storage warehouse of the previous embodiment, so the difference will be mainly described here.

第１土層２１は、倉庫本体１４の外面を覆うのみならず掘削底面１７から掘削側面１８ａ，１８ｂの一部までを覆うように形成され、その上面は平坦面２３となっている。平坦面２３の上にはシート体１３が平面状に設置されている。シート体１３は、少なくとも倉庫本体１４の平面視における範囲を覆う大きさに設定され、配置されている。第１土層２１の上面にはシート体１３を覆うように第２土層２７が形成されている。具体的には、第２土層２７は掘削側面１８ａ，１８ｂの残部を覆い、その上面が地面１６の面に整列するように形成されている。尚、シート体１３の倉庫本体１４の平面視に対する余剰程度は、爆土圧の緩和に対して必要な第１土層２１の厚さに応じて雨水等が影響しないように決定すれば良い。   The first soil layer 21 is formed so as to cover not only the outer surface of the warehouse main body 14 but also from the excavation bottom surface 17 to a part of the excavation side surfaces 18a and 18b, and the upper surface thereof is a flat surface 23. On the flat surface 23, the sheet body 13 is installed in a planar shape. The sheet body 13 is set and arranged so as to cover at least a range of the warehouse body 14 in a plan view. A second soil layer 27 is formed on the upper surface of the first soil layer 21 so as to cover the sheet body 13. Specifically, the second soil layer 27 is formed so as to cover the remaining portions of the excavation side surfaces 18 a and 18 b and the upper surface thereof is aligned with the surface of the ground 16. In addition, what is necessary is just to determine the excess degree with respect to the planar view of the warehouse main body 14 of the sheet | seat body 13 so that rainwater etc. may not affect according to the thickness of the 1st soil layer 21 required with respect to relaxation of explosive pressure.

このように構成されているため、第２土層２７を介して外面から浸み込んだ雨水等はシート体１３の下方の第１土層２１の部分に浸透することは無い。即ち、倉庫本体１４の上部の第１土層２１の部分が保有する水分量は常に一定となる。その結果、火薬類の爆発による地盤振動の周囲への影響が一定化するので、貯蔵倉庫１１周りに必要な保安距離の確保が容易となる。又、シート体１３は第１土層２１の平坦面２３の一部を覆っていると共に、その外面は第２土層２７で覆われているため、爆発時におけるシート体１３が捲りあがることがない。その結果、シート体１３に伝達された爆風等は外部に拡散されることがない。   Since it is configured in this manner, rainwater or the like soaked from the outer surface through the second soil layer 27 does not penetrate into the portion of the first soil layer 21 below the sheet body 13. That is, the amount of water held by the portion of the first soil layer 21 at the top of the warehouse body 14 is always constant. As a result, the influence of ground vibration due to the explosion of explosives is made constant, so that it is easy to secure a necessary safety distance around the storage warehouse 11. Further, since the sheet body 13 covers a part of the flat surface 23 of the first soil layer 21 and the outer surface thereof is covered with the second soil layer 27, the sheet body 13 may be rolled up at the time of explosion. Absent. As a result, the blast transmitted to the sheet body 13 is not diffused outside.

図４はこの発明の第３の実施の形態による貯蔵倉庫の概略断面図であって、第１の実施の形態による図２に対応した図である。   FIG. 4 is a schematic sectional view of a storage warehouse according to the third embodiment of the present invention and corresponds to FIG. 2 according to the first embodiment.

図を参照して、基本的な構成は第１の実施の形態の貯蔵倉庫と同一であるので、ここではその相違点について主に説明する。   With reference to the drawing, the basic configuration is the same as that of the storage warehouse of the first embodiment, and therefore, the difference will be mainly described here.

第１土層２１をシート体１３で覆う点までは第１の実施の形態による貯蔵倉庫と同一であるが、この実施の形態の貯蔵倉庫１１にあっては、第２土層２９ａ，２９ｂの形成範囲が大きく異なっている。即ち、第２土層２９ａ，２９ｂは、シート体１３の外面全面を覆うものではなく、各々がシート体１３の側面部分の各々と掘削側面１８ａ，１８ｂの各々との間のスペースを埋めるように形成されている。そして、シート体１３の上面と第２土層２９ａ，２９ｂの上面とは地面１６の面に整列されるように形成されている。   The point up to the point where the first soil layer 21 is covered with the sheet body 13 is the same as the storage warehouse according to the first embodiment, but in the storage warehouse 11 of this embodiment, the second soil layers 29a, 29b The formation range is very different. That is, the second soil layers 29a and 29b do not cover the entire outer surface of the sheet body 13, but each fills a space between each of the side surface portions of the sheet body 13 and each of the excavation side surfaces 18a and 18b. Is formed. The upper surface of the sheet body 13 and the upper surfaces of the second soil layers 29 a and 29 b are formed so as to be aligned with the surface of the ground 16.

これによって、第１土層２１の水分保有量は一定となるため、地盤振動の低減効果を発揮すると共に、シート体１３の上面に向かう爆風等はシート体１３によって阻止されることになる。又、第２土層２９ａ，２９ｂは、シート体１３の平坦部１９ａ，１９ｂの上に形成されているので、シート体１３の捲りあがりを防止する効果も奏する。そして、この実施の形態による貯蔵倉庫にあっては、第２土層を形成しないため、倉庫本体１４の設置のための掘削深さを低減すると共に、設置工程がより簡略化する。   As a result, the moisture content of the first soil layer 21 is constant, so that the effect of reducing ground vibration is exhibited, and blasts and the like toward the upper surface of the sheet body 13 are blocked by the sheet body 13. Further, since the second soil layers 29a and 29b are formed on the flat portions 19a and 19b of the sheet body 13, there is also an effect of preventing the sheet body 13 from being rolled up. In the storage warehouse according to this embodiment, since the second soil layer is not formed, the excavation depth for installing the warehouse body 14 is reduced and the installation process is further simplified.

図５はこの発明の第４の実施の形態による貯蔵倉庫の概略断面図であって、第２の実施の形態による図３に対応した図である。   FIG. 5 is a schematic sectional view of a storage warehouse according to the fourth embodiment of the present invention and corresponds to FIG. 3 according to the second embodiment.

図を参照して、基本的な構成は第２の実施の形態の貯蔵倉庫と同一であるので、ここではその相違点について主に説明する。   With reference to the drawing, the basic configuration is the same as that of the storage warehouse of the second embodiment, and therefore, the difference will be mainly described here.

倉庫本体１４の上方であって第１土層２１の平坦面２３の一部をシート体１３で覆う点までは第２の実施の形態による貯蔵倉庫と同一である。しかし、この実施の形態の貯蔵倉庫１１にあっては、第１土層２１の平坦面２３は地面１６の面に整列しており、その上面にはシート体１３が設置されているだけで、第２の実施の形態のような第２土層は形成されていない。尚、シート体１３は掘削面等を利用して上方に飛散しないようにワイヤー等で固定しておくことが好ましい。   The point up to the point where the sheet body 13 covers a part of the flat surface 23 of the first soil layer 21 above the warehouse main body 14 is the same as the storage warehouse according to the second embodiment. However, in the storage warehouse 11 of this embodiment, the flat surface 23 of the first soil layer 21 is aligned with the surface of the ground 16, and the sheet body 13 is only installed on the upper surface. The second soil layer as in the second embodiment is not formed. In addition, it is preferable to fix the sheet | seat body 13 with a wire etc. so that it may not scatter upward using an excavation surface.

これによって、倉庫本体周りの第１土層２１の水分保有量は一定となるため、地盤振動の低減効果を発揮すると共に、上面に向かう爆風等はシート体１３によって阻止されることになる。そして、この実施の形態による貯蔵倉庫にあっては、第２土層を形成しないため、倉庫本体１４の設置のための掘削深さを低減すると共に、設置工程がより簡略化する。   As a result, the moisture content of the first soil layer 21 around the warehouse main body becomes constant, so that the effect of reducing ground vibration is exhibited and the blast and the like toward the upper surface are blocked by the sheet body 13. In the storage warehouse according to this embodiment, since the second soil layer is not formed, the excavation depth for installing the warehouse body 14 is reduced and the installation process is further simplified.

尚、上記の各実施の形態では、シート体は総ゴム製の遮水シートを用いているが、ゴム材料に繊維、金網等からなる補強材を内部に埋設又は表面に被覆したシート材や合成樹脂性のシート材等を用いても良い。   In each of the above-described embodiments, the sheet body uses a water-proof sheet made of total rubber, but a sheet material or synthetic material in which a reinforcing material made of fiber, wire mesh or the like is embedded in the rubber material or coated on the surface is used. A resinous sheet material or the like may be used.

又、上記の各実施の形態では、シート体の設置形態については触れていないが、設置時にできるだけ角部等が表れないように設置すれば、シート体の破断を防止する意味で好ましい。   In each of the above embodiments, the installation form of the sheet body is not mentioned, but it is preferable to install the sheet body so that the corners and the like do not appear as much as possible at the time of installation in order to prevent the sheet body from being broken.

更に、上記の各実施の形態では、シート体は一枚で使用しているが、状況に応じて複数枚を重ねて使用しても良い。   Further, in each of the above-described embodiments, the sheet body is used as a single sheet, but a plurality of sheets may be used depending on the situation.
