As shown in FIGS. 4 to 5 and the like, a steel sheet pile wall 103 in which a steel sheet pile 102 is continuous is formed on the side surface of the cut hole 101. In actual construction, a steel sheet pile 102 as a sheet pile is formed at the side surface position of the cut hole 101 to form a continuous steel sheet pile wall 103, and then the steel sheet pile walls 103, 103 on both sides are excavated. A cut hole 101 is formed.

このような現場で壁構造を形成する際、壁用型枠ブロック１を用いる。図１に示すように、その壁用型枠ブロック１は、縦方向より幅方向の大きな外面部たる外板部２と、この外板部２の両端側に設けられ内面側に突出された腕部３，３とを一体に備え、前記外板部２は正面長方形形状で平板状をなし、さらに、前記外板部２の内面には複数の鉄筋４を突設し、この鉄筋４は幅方向に並んで上下複数段に配置されている。尚、この鉄筋４はコ字状のジベルである。そして、前記外板部２と腕部３，３の上，下面５，５が水平で平坦に形成されて、ブロック１，１相互が上下に積み上げ可能となっており、積み上げ状態で自立する。また、前記外板部２と腕部３とは同一厚さであり、前記鉄筋４の先端と外板部２との間隔である鉄筋突出寸法は、前記腕部３の突出寸法より大である。   When forming a wall structure at such a site, the wall form block 1 is used. As shown in FIG. 1, the wall formwork block 1 includes an outer plate portion 2 that is an outer surface portion that is larger in the width direction than the vertical direction, and arms that are provided at both ends of the outer plate portion 2 and protrude toward the inner surface side. The outer plate portion 2 has a front rectangular shape and a flat plate shape, and a plurality of reinforcing bars 4 project from the inner surface of the outer plate portion 2, and the reinforcing bar 4 has a width. Arranged in multiple directions above and below the direction. The reinforcing bar 4 is a U-shaped gibber. The upper and lower surfaces 5 and 5 of the outer plate portion 2 and the arm portions 3 and 3 are formed to be horizontal and flat so that the blocks 1 and 1 can be stacked up and down, and are independent in the stacked state. Further, the outer plate portion 2 and the arm portion 3 have the same thickness, and the reinforcing bar protruding dimension that is the distance between the tip of the reinforcing bar 4 and the outer plate portion 2 is larger than the protruding dimension of the arm portion 3. .

図２は、調整用の壁用型枠ブロック１Ａを示し、このブロック１Ａは高さ寸法が前記ブロック１の略２分の１で、鉄筋４が一段に設けられている以外は前記ブロック１と同一構成である。尚、ブロック１，１Ａはプレキャストコンクリート製である。また、その型枠用ブロック１Ａのみを用いて壁構造を構築するようにしてもよい。   FIG. 2 shows a wall form block 1A for adjustment. This block 1A is approximately half the height of the block 1, and the block 1 is the same as the block 1 except that the reinforcing bars 4 are provided in one stage. It is the same configuration. The blocks 1 and 1A are made of precast concrete. Moreover, you may make it construct | assemble a wall structure using only the block 1A for formwork.

通路や水路などを構成する地中構造物11は、その壁体12に前記ブロック１，１Ａを用いる。また、構造物11の底版部13と壁体12との間に位置するコーナー部14には、プレキャストコンクリート製の基礎ブロック21を用いる。   The underground structure 11 constituting a passage or a water channel uses the blocks 1 and 1A for the wall body 12 thereof. A foundation block 21 made of precast concrete is used for the corner portion 14 located between the bottom slab portion 13 of the structure 11 and the wall body 12.

この基礎ブロック21は、断面略Ｌ型で、前記ブロック１，１Ａを重ねる上面部22と、地中構造物11の中央側に向いた縦方向の底版形成面23とを備え、前記上面部22の内端と底版形成面23の上端とを凹状彎曲面24により連結している。前記基礎ブロック21の上面部22及び底版形成面23には複数の連結鉄筋25が突設されている。これら連結鉄筋25が現場打ちコンクリートに埋設されることにより、壁体12のコンクリートと底版部13のコンクリートと前記基礎ブロック21が一体化される。また、前記ブロック１，１Ａは基礎ブロック21より構造物長さ方向に長く形成されている。   The basic block 21 has a substantially L-shaped cross section, and includes an upper surface portion 22 on which the blocks 1 and 1A are overlapped, and a vertical bottom plate forming surface 23 facing the center side of the underground structure 11. Are connected to the upper end of the bottom plate forming surface 23 by a concave saddle curved surface 24. A plurality of connecting reinforcing bars 25 protrude from the upper surface portion 22 and the bottom plate forming surface 23 of the foundation block 21. By embedding these connecting reinforcing bars 25 in the cast-in-place concrete, the concrete of the wall body 12, the concrete of the bottom slab portion 13, and the foundation block 21 are integrated. The blocks 1 and 1A are longer than the base block 21 in the structure length direction.

次に、前記構成につき、施工方法を合わせて説明すると、開削孔101には、両側の鋼矢板壁103，103の間に切り梁104，104Ａを上下多段に設ける（図中は上下２段を図示）。この例では、鋼矢板壁103が型枠構成体である。鋼矢板壁103により開削孔101の側面の土留めを施した後、開削孔101の底部を均し、地中構造物11の基礎として、前記開削孔101の底部に基礎砕石層105を設け、この基礎砕石層105の上に現場打ちコンクリートにより基礎コンクリート層106を形成し、この基礎コンクリート層106の上面を平坦に形成する。   Next, the construction method will be described with respect to the construction described above. In the excavation hole 101, cut beams 104, 104A are provided in upper and lower multi-stages between the steel sheet pile walls 103, 103 on both sides (in the figure, two upper and lower stages are provided). (Illustrated). In this example, the steel sheet pile wall 103 is a formwork structure. After the earth retaining of the side surface of the cut hole 101 by the steel sheet pile wall 103, the bottom of the cut hole 101 is leveled, as a foundation of the underground structure 11, a basic crushed stone layer 105 is provided at the bottom of the cut hole 101, A foundation concrete layer 106 is formed on the foundation crushed stone layer 105 by in-situ concrete, and the upper surface of the foundation concrete layer 106 is formed flat.

このようにして基礎が完成したら、底版形成面23を中央側に向けて、開削孔101の幅方向両側に基礎ブロック21を該開削孔101の長さ方向に複数並べる。この後、両側の基礎ブロック21の間で基礎上に現場打ちコンクリートを打設し、この現場打ちコンクリート部107と両側の基礎ブロック21とが一体となって前記底版部13が形成される。また、前記基礎ブロック21の上にブロック１を積み上げ、腕部３の先端と鋼矢板壁103との間に所定の間隔を置く。また、左右方向に隣り合うブロック１，１同士は腕部３，３の端面を突き合わせる。この例では、ブロック１を上下４段に積み重ねるが、まず、下段の切り梁104Ａの下までブロック１を重ねる。この場合、切り梁104Ａは下から２段目のブロック１の位置にあるから、その下の１段目のブロック１を並べる。並べたブロック１は、コンクリートを充填するまで、必要に応じて適宜手段により仮固定するようにしても良い。このようにして切り梁104Ａの下までブロック１を並べたら、図５に示すように、ブロック１の内面と鋼矢板壁103との間に、ブロック１の上部高さ位置まで現場打ちコンクリート108を充填する。尚、この場合、この壁構造における１回目のコンクリートの打設と、前記現場打ちコンクリート部107のコンクリートの打設を同時に行ってもよい。現場打ちコンクリート108が所定の強度まで硬化したら、鋼矢板壁103と該コンクリート108とブロック１とが一体となった壁構造の下部が形成され、この壁構造の下部により鋼矢板壁103を押える力が得られる。したがって、ブロック１の上の切り梁104Ａを外すことができ、この切り梁104Ａを外した後、上段の切り梁104の下までブロック１を重ね合わせ、すなわち、この例では、ブロック１を基礎ブロック21の上に三段に重ね合わせた後、ブロック１と鋼矢板壁103との間に現場打ちコンクリート108を充填し、このコンクリート108が所定の強度まで硬化したら、上段の切り梁104を取外し、この外した部分にブロック１を重ね合わせ、ブロック１と鋼矢板壁103の上部に現場打ちコンクリート108を充填し、このようにして開削孔101の下部から上部に至る壁構造たる壁体12を形成する。   When the foundation is completed in this way, a plurality of foundation blocks 21 are arranged in the length direction of the cut hole 101 on both sides in the width direction of the cut hole 101 with the bottom plate forming surface 23 facing the center. Thereafter, the cast-in-place concrete is cast on the foundation between the foundation blocks 21 on both sides, and the bottom slab portion 13 is formed by integrating the cast-in-place concrete portion 107 and the foundation blocks 21 on both sides. Further, the block 1 is stacked on the foundation block 21, and a predetermined interval is placed between the tip of the arm portion 3 and the steel sheet pile wall 103. Also, the blocks 1, 1 adjacent in the left-right direction abut the end surfaces of the arm portions 3, 3. In this example, the blocks 1 are stacked in four upper and lower stages. First, the blocks 1 are stacked below the lower cut beam 104A. In this case, since the cut beam 104A is at the position of the second block 1 from the bottom, the first block 1 below is arranged. The arranged blocks 1 may be temporarily fixed by appropriate means as necessary until the concrete is filled. When the blocks 1 are arranged below the beam 104A in this way, the cast-in-place concrete 108 is placed between the inner surface of the block 1 and the steel sheet pile wall 103 to the upper height position of the block 1 as shown in FIG. Fill. In this case, the first placement of the concrete in the wall structure and the placement of the concrete in the on-site cast-in concrete portion 107 may be performed simultaneously. When the cast-in-place concrete 108 is hardened to a predetermined strength, a steel sheet pile wall 103 and a lower part of the wall structure in which the concrete 108 and the block 1 are integrated are formed, and a force for pressing the steel sheet pile wall 103 by the lower part of the wall structure. Is obtained. Therefore, the cut beam 104A above the block 1 can be removed, and after removing the cut beam 104A, the block 1 is overlaid under the upper cut beam 104, that is, in this example, the block 1 is the basic block. After being stacked in three steps on 21, the cast-in-place concrete 108 is filled between the block 1 and the steel sheet pile wall 103, and when the concrete 108 is cured to a predetermined strength, the upper beam 104 is removed, Block 1 is overlaid on this removed part, and the upper part of block 1 and steel sheet pile wall 103 is filled with cast-in-place concrete 108, thus forming wall 12 which is a wall structure extending from the bottom of cut hole 101 to the top. To do.

The upper and lower surfaces 5 and 5 of the outer plate portions 2 and 2 are formed horizontally and flatly so that the blocks 1 and 1 can be stacked up and down.

図１０は、調整用の壁用型枠ブロック１Ｃを示し、このブロック１Ｃは前記ブロック１Ｂを上下に２分割した形状をなし、幅方向両側に設けられ壁体の外面を形成する外板部，２と、これら両側の外板部，２とを連結する連結腕部６，６とを備え、この連結腕部６は一箇所に複数設けられている。また、前記外板部２と連結腕部６とは同一厚さである。   FIG. 10 shows a wall formwork block 1C for adjustment. The block 1C has a shape obtained by dividing the block 1B into two vertically and an outer plate portion provided on both sides in the width direction and forming the outer surface of the wall body. 2 and connecting arm portions 6 and 6 for connecting the outer plate portions 2 and 2 on both sides, and a plurality of connecting arm portions 6 are provided at one place. Moreover, the said outer-plate part 2 and the connection arm part 6 are the same thickness.

通路や水路などを構成する地中構造物11は、その壁体12に前記ブロック１Ｂ，１Ｃを用いる。また、構造物11の底版部13と壁体12とのコーナー部には、プレキャストコンクリート製の前記基礎ブロック21を用いる。   The underground structure 11 constituting a passage or a water channel uses the blocks 1B and 1C for the wall 12 thereof. Further, the foundation block 21 made of precast concrete is used at the corner portion between the bottom plate portion 13 and the wall body 12 of the structure 11.

次に、前記構成につき、施工方法を合わせて説明すると、開削孔101には、両側の鋼矢板壁103，103の間に切り梁104，104Ａを上下多段に設けている（図中は上下２段を図示）。この例では、鋼矢板壁103を型枠して用いる必要はない。上記第１実施例と同様に、開削孔101の底部に基礎を形成したら、底版形成面23を中央側に向けて、開削孔101の幅方向両側に基礎ブロック21を該開削孔101の長さ方向に複数並べる。この後、両側の基礎ブロック21の間に現場打ちコンクリート107を打設し、この現場打ちコンクリート部107と両側の基礎ブロック21とが一体となって前記底版部13が形成される。また、前記基礎ブロック21の上にブロック１Ｂを積み上げる。この例では、ブロック１Ｂを上下４段に積み重ねるが、切り梁104Ａの下までブロック１Ｂを重ねる。この場合、切り梁104Ａは下から２段目のブロック１Ｂの位置にあるから、その下の１段目のブロック１Ｂを並べる。並べたブロック１Ｂは、コンクリートを充填するまで、必要に応じて適宜手段により仮固定するようにしても良い。このようにして切り梁104Ａの下までブロック１Ｂを並べたら、ブロック１Ｂの厚さ方向両側の外板部２，２の間に、ブロック１Ｂの上部高さ位置まで現場打ちコンクリート108を充填する。尚、この場合、この壁構造における１回目のコンクリートの打設と、前記現場打ちコンクリート部107のコンクリートの打設を同時に行ってもよい。さらに、ブロック１Ｂと鋼矢板壁103との間に、土砂などの埋め戻し材111を充填して埋め戻す。現場打ちコンクリート108が所定の強度まで硬化したら、幅方向両側の外板部２，２が型枠代わりとなって、並べたブロック１Ｂとコンクリート108とブロック１とが一体となった壁体12の下部が形成され、この壁体12の下部により鋼矢板壁103を押える力が得られる。したがって、ブロック１Ｂの上の切り梁104Ａを外すことができ、この切り梁104Ａを外した後、上段の切り梁104の下までブロック１Ｂを重ね合わせ、すなわち、この例では、ブロック１Ｂを基礎ブロック21の上に三段に重ね合わせた後、ブロック１Ｂの外板部２，２の間に現場打ちコンクリート108を充填し、さらに、ブロック１Ｂと鋼矢板壁103との間に、土砂などの埋め戻し材111を充填して埋め戻し、コンクリート108が所定の強度まで硬化したら、上段の切り梁104を取外し、この外した部分にブロック１Ｂを重ね合わせ、ブロック１Ｂと鋼矢板壁103の上部に現場打ちコンクリート108を充填し、さらに、ブロック１Ｂと鋼矢板壁103との間に、土砂などの埋め戻し材111を充填して埋め戻し、このようにして開削孔101の下部から上部に至る壁構造たる壁体12を形成する。   Next, the construction method will be described with reference to the construction method. In the excavation hole 101, cut beams 104, 104A are provided in upper and lower stages between the steel sheet pile walls 103, 103 on both sides (up and down two in the figure). Steps are shown). In this example, it is not necessary to use the steel sheet pile wall 103 as a mold. As in the first embodiment, when the foundation is formed at the bottom of the cut hole 101, the base plate forming surface 23 faces the center, and the foundation blocks 21 are arranged on both sides in the width direction of the cut hole 101. Arrange several in the direction. Thereafter, the cast-in-place concrete 107 is placed between the foundation blocks 21 on both sides, and the bottom slab portion 13 is formed by integrating the cast-in-place concrete portion 107 and the foundation blocks 21 on both sides. Further, the block 1B is stacked on the foundation block 21. In this example, the blocks 1B are stacked up and down in four stages, but the blocks 1B are stacked under the beam 104A. In this case, since the cut beam 104A is at the position of the second block 1B from the bottom, the first block 1B below is arranged. The arranged blocks 1B may be temporarily fixed by appropriate means as needed until the concrete is filled. When the blocks 1B are arranged below the cutting beam 104A in this way, the cast-in-place concrete 108 is filled between the outer plate portions 2 and 2 on both sides in the thickness direction of the block 1B to the upper height position of the block 1B. In this case, the first placement of the concrete in the wall structure and the placement of the concrete in the on-site cast-in concrete portion 107 may be performed simultaneously. Further, a backfill material 111 such as earth and sand is filled between the block 1B and the steel sheet pile wall 103 and backfilled. When the cast-in-place concrete 108 is cured to a predetermined strength, the outer plate portions 2 and 2 on both sides in the width direction are used as a formwork, and the wall body 12 in which the arranged block 1B, the concrete 108 and the block 1 are integrated is formed. A lower part is formed, and a force for pressing the steel sheet pile wall 103 by the lower part of the wall body 12 is obtained. Therefore, the cut beam 104A on the block 1B can be removed, and after removing the cut beam 104A, the block 1B is overlaid under the upper cut beam 104, that is, in this example, the block 1B is replaced with the basic block. After being layered on top of 21, the cast-in-place concrete 108 is filled between the outer plate parts 2 and 2 of the block 1 B, and earth and sand are buried between the block 1 B and the steel sheet pile wall 103. When the back material 111 is filled and backfilled, and the concrete 108 is hardened to a predetermined strength, the upper beam 104 is removed, and the block 1B is overlaid on the removed portion, and the block 1B and the steel sheet pile wall 103 are placed on the site. Filled with cast concrete 108, and then backfilled with a backfill material 111 such as earth and sand between the block 1B and the steel sheet pile wall 103, and thus the wall structure extending from the lower part to the upper part of the excavated hole 101 Dripping To form a body 12.

したがって、壁体12が完成した後は、必要に応じて鋼矢板102を引き抜くようにしてもよい。一方、埋め戻し材に現場打ちコンクリートを用いれば、壁体12と鋼矢板壁103とが一体化されて強度的に優れた壁構造が得られ、この場合は鋼矢板102は引き抜かない。   Therefore, after the wall body 12 is completed, the steel sheet pile 102 may be pulled out as necessary. On the other hand, if cast-in-place concrete is used for the backfill material, the wall body 12 and the steel sheet pile wall 103 are integrated to obtain a wall structure with excellent strength. In this case, the steel sheet pile 102 is not pulled out.

尚、地中構造物11の上部は開口していてもよいし、蓋体（図示せず）などにより閉塞していてもよい。尚、図１３の斜視図では、鋼矢板102及び鋼矢板壁103を図示省略している。   The upper part of the underground structure 11 may be opened or may be closed by a lid (not shown) or the like. In the perspective view of FIG. 13, the steel sheet pile 102 and the steel sheet pile wall 103 are not shown.

By stacking and arranging in the left-right direction and filling the cast-in-place concrete 108 between the outer plate portions 2 and 2 on both sides of the block 1B, the wall body 12 having both sides constituted by the outer plate portions 2 and 2 of the block 1B is formed. Can be built on site.

また、このように本参考例では、上記壁用型枠ブロック１Ｂを上下方向に積み上げられると共に左右方向に並べ、両側の外面部たる外板部２，２の間にコンクリート108を充填してなるから、ブロック１Ｂの両面を型枠に利用して、壁体12を現場で簡便に構築することができる。 In this way, in this reference example, the above-mentioned wall form blocks 1B are stacked in the vertical direction and arranged in the horizontal direction, and the concrete 108 is filled between the outer plate portions 2 and 2 which are the outer surface portions on both sides. Therefore, the wall body 12 can be easily constructed on site by using both sides of the block 1B as a mold.

また、このように本参考例では、上記壁構造を備えた地中構造物の施工方法において、開削孔101の側面に沿って壁構造たる壁体12を設ける際、開削孔101の側面に沿って、壁用型枠ブロック１Ｂを左右方向に並べると共に壁体12の途中の高さまで積み上げた後、コンクリート108を充填し、壁用型枠ブロック１Ｂの積み上げとコンクリート108の充填を複数回分けて所定高さ毎に行うから、開削孔101の側面間に切り梁104，104Ａなどを設けるなどして施工に制約がある現場でも、ブロック１Ｂを途中まで積み上げて壁体12の一部を構築した後、切り梁104，104Ａを取外し、その途中の壁体12の上にブロック１Ｂを積み重ね、高さ方向に複数回に分けてコンクリート108を打設することにより、壁体12を構築できる。 Also, in this way the reference example, in the construction method of the underground structure having the above wall structure, when providing a wall structure serving wall 12 along the sides of the excavation hole 101, along the sides of the excavation hole 101 After the wall formwork blocks 1B are arranged in the left-right direction and stacked up to a height in the middle of the wall body 12, the concrete 108 is filled, and the stacking of the wall formwork blocks 1B and the filling of the concrete 108 are divided into a plurality of times. Since it is performed every predetermined height, even in the site where construction is restricted by providing cut beams 104, 104A, etc. between the side surfaces of the cut hole 101, a part of the wall 12 is constructed by stacking the blocks 1B halfway. Then, the wall body 12 can be constructed by removing the cut beams 104 and 104A, stacking the blocks 1B on the wall body 12 in the middle, and placing the concrete 108 in a plurality of times in the height direction.

また、両側の外板部２が型枠代わりとなるから、他に型枠構成体の無い現場でも、壁構造を簡便に構築することができる。   In addition, since the outer plate portions 2 on both sides serve as a formwork, a wall structure can be easily constructed even in the field where there is no other formwork structure.
