Description

本発明は、擁壁用L型コンクリートブロック(以下、擁壁用L型ブロックという)を利用する宅地造成の境界壁や道路の路肩等の、擁壁構築の基礎を造成する施工法と完成後の基礎構造に関する。  The present invention is a construction method for constructing a foundation for retaining wall construction, such as a boundary wall for building a residential land using an L-shaped concrete block for retaining walls (hereinafter referred to as an L-shaped block for retaining walls) or a road shoulder, and after completion. Related to the basic structure.

擁壁用L型ブロックを使用して擁壁を構築する場合、従来は図31に例示する通り、基礎土36の上に水平面の基礎コンクリート23を造成し、その上に成形された基礎ブロック35を順次敷設し、この基礎ブロック35の上に擁壁用L型ブロック3を順次据付けて固定するという施工法であった。そして、基礎ブロック35及び擁壁用L型ブロック3の根元部分は、施工後に地表面下に埋め込んでいた。  When the retaining wall is constructed using the retaining wall L-shaped block, as shown in FIG. 31, conventionally, the horizontal foundation concrete 23 is formed on the foundation soil 36, and the foundation block 35 formed thereon is formed. Was constructed in order, and the retaining wall L-shaped block 3 was sequentially installed and fixed on the foundation block 35. And the base part 35 and the base part of the L-type block 3 for retaining walls were embedded under the ground surface after construction.

この場合、擁壁用L型ブロックは、多用する通常のものでも、重量1トン、高さ2mもあるので、正規位置に据え付ける作業は能率が低下する為、先ず、軽量、小形で作業性のよい基礎ブロックを基礎コンクリー23上に水平状に敷設して基礎面を造成する事が行われているが、従来の基礎ブロックは、擁壁用L型ブロック3’を載置するだけの効用で、単なる載置台であり、据付ける擁壁用L型ブロックの据付け位置決めや連結、固定ができる構造ではなかった。また、基礎コンクリート23の上面も、擁壁用L型ブロック3’の据付け位置決めや、その底面を嵌合して固定する構造及び形状ではなく、単に基礎ブロク35を載置して敷設するだけの平面であった。  In this case, the retaining wall L-shaped block is 1 ton and 2 m in height even if it is a regular one that is frequently used. Although a good foundation block is laid horizontally on the foundation concrete 23 to create a foundation surface, the conventional foundation block has the effect of only placing the L-shaped block 3 ′ for retaining walls. It was just a mounting table, and it was not a structure that could install, position, connect, and fix the retaining wall L-shaped block. Further, the top surface of the foundation concrete 23 is not simply installed and positioned for the retaining wall L-shaped block 3 ′, and the structure and shape for fitting and fixing the bottom surface thereof, but the foundation block 35 is simply placed and laid. It was a plane.

従来の擁壁用L型ブロックを利用する擁壁構築の基礎の施工法は、基礎コンクリート上に敷設した基礎プロック35は、擁壁用L型ブロック3’を載置するだけの単なる載置台の効用に留まったので、基礎ブロック35の固定及びその上に据付ける重量、寸法のきい擁壁用L型ブロック3’の位置決めの調整と固定の作業は、施工工事が機械化したとはいえ、施工効率の低下の要因であり、工期延長の原因ともなっていた。  The construction method of the foundation of the retaining wall construction using the conventional retaining wall L-shaped block is that the foundation block 35 laid on the foundation concrete is a simple mounting table for placing the retaining wall L-shaped block 3 '. Because it remained in effect, the work of fixing and fixing the foundation block 35 and the positioning and fixing of the L-shaped block 3 'for the retaining wall with the weight and dimensions installed on the foundation block 35 It was a factor of efficiency reduction and also a cause of extension of construction period.

本発明は、基礎コンクリート23の造成に続いて、その上に、コンクリートを打ち込んでL型ブロック基礎台7を造成する際、コンクリートの凝固前に、その上面に配置した上面型枠に追加コンクリートを充填して基礎側嵌合構造を成形する施工法であり、工事現場において、基礎コンクリートと、上面に嵌合構造を設けたその上側のL型ブロック基礎台7を一体化するものである。  In the present invention, following the creation of the foundation concrete 23, when the concrete is driven onto the L-type block foundation base 7, the additional concrete is added to the upper formwork arranged on the upper surface before the concrete is solidified. In this construction method, the foundation-side fitting structure is filled and the foundation concrete is integrated with the upper L-shaped block foundation 7 provided with the fitting structure on the upper surface at the construction site.

擁壁用L型ブロックの基礎である基礎ブロックに要求される要件は、基礎コンクリートへの固定、据付けた擁壁用L型ブロックとの連結、固定、等に対して有効な構造、形状であるという事である。本発明による基礎施工法は、基礎コンクリートや擁壁用L型ブロックとの連結要件が不備である従来の基礎ブロックとは異なり、工事現場において、基礎コンクリートの打込みと同時進行で施工する事ができる能率的な施工法であり、又、基礎コンクリートの上面に造成されるL型ブロック基礎台は、擁壁の構築方向に一体化して連続し、その上面の基礎側嵌合構造は擁壁用L型ブロックの垂直壁底面を連結して固定するので、基礎ブロックに要求される要件を充足する条件を具備する構造、形状であり、結果として、上面に据付けた擁壁用L型ブロックの滑動、傾倒、沈降、転倒等の移動を防止する為に有効に作用する。  The requirements for the foundation block, which is the foundation of the retaining wall L-shaped block, are an effective structure and shape for fixing to the foundation concrete, connection with the installed retaining wall L-shaped block, fixing, etc. That's it. The foundation construction method according to the present invention can be constructed at the construction site simultaneously with the placement of the foundation concrete, unlike the conventional foundation block in which the connection requirement with the foundation concrete and the L-shaped block for retaining wall is insufficient. It is an efficient construction method, and the L-type block foundation built on the upper surface of the foundation concrete is integrated and continuous in the direction of the retaining wall construction. Since the bottom of the vertical wall of the mold block is connected and fixed, the structure and shape satisfy the conditions required for the foundation block. As a result, the sliding of the L-shaped block for the retaining wall installed on the upper surface, It works effectively to prevent movement such as tilting, settling and falling.

本発明に係る基礎施工法は、基礎土36の上に造成した基礎コンクリート23の上側に、工事現場においてコンクリートを打込んで、上面が略水平面に形成されたL型ブロック基礎台7を造成し、その上側に上面型枠を設置し、打込んだL型ブロック基礎台7のコンクリートが凝固する前に上面型枠に追加コンクリート22を充填して、L型ブロック基礎台7の上面に、擁壁用L型ブロック3の垂直壁底面に形成されたブロック側嵌合構造と合致して嵌合する基礎嵌合構造を成形する施工法であり、上面に基礎嵌合構造を設けたL型ブロック基礎台7は、基礎コンクリート23と一体化した状態で基礎コンクリート23と共に連続する。  In the foundation construction method according to the present invention, an L-shaped block foundation 7 having an upper surface formed in a substantially horizontal plane is formed by placing concrete at the construction site on the upper side of the foundation concrete 23 created on the foundation soil 36. An upper surface formwork is installed on the upper side, and the upper surface formwork is filled with additional concrete 22 before the concrete of the placed L-type block foundation 7 is solidified. This is a construction method for forming a basic fitting structure that fits and fits with the block-side fitting structure formed on the bottom surface of the vertical wall of the L-shaped block 3 for the wall. The foundation platform 7 is continuous with the foundation concrete 23 in an integrated state with the foundation concrete 23.

本発明による施工法では、L型ブロック基礎台の上面の基礎側嵌合構造を成形する為の追加コンクリート充填は、L型ブロック基礎台の上側に配置した上面型枠に充填する事により行うが、L型ブロック基礎台へ充填したコンクリートの凝固前に続けて行うので、L型ブロック基礎台へのコンクリートの充填と殆ど同時進行で作業時間の無駄なく施工する事ができる。又、上面型枠に充填する追加コンクリートは、殆ど基礎側嵌合構造の成形に要するだけてあるから小量で足り、L型ブロック基礎台7の上面を水平面とする事や、凹凸により構成される基礎嵌合構造は、成形する事が容易であり、この際、ボルト等の鉄材を埋め込んで補強する事も簡単に行う事ができる。  In the construction method according to the present invention, the additional concrete filling for forming the foundation-side fitting structure on the upper surface of the L-shaped block foundation is performed by filling the upper-surface mold frame arranged on the upper side of the L-shaped block foundation. Since it is carried out before solidification of the concrete filled in the L-type block foundation, it can be constructed without waste of working time almost simultaneously with the filling of the concrete into the L-type block foundation. Further, the additional concrete to be filled in the upper surface formwork is almost necessary for forming the foundation-side fitting structure, so that a small amount is sufficient. The basic fitting structure can be easily molded, and at this time, it is also possible to easily reinforce by embedding iron materials such as bolts.

従来は、基礎コンクリートを水平面に形成しなければ基礎ブロックを水平状態に据付ける事が困難であるから、基礎コンクリートの打込み時と基礎ブロックの敷設時の2回に亘って水平面形成の調整を行っていたが、本発明の施工法においては、水平面形成の調整はL型ブロック基礎台の造成時の1回だけで足りるので、施工時間が短縮され、基礎造成作業は極めて能率的となる。  Conventionally, since it is difficult to install the foundation block horizontally unless the foundation concrete is formed on a horizontal plane, the horizontal plane formation is adjusted twice when the foundation concrete is driven and when the foundation block is laid. However, in the construction method of the present invention, the horizontal plane formation is adjusted only once during the construction of the L-shaped block foundation, so that the construction time is shortened and the foundation construction work becomes extremely efficient.

本発明は、図1、図2、図3及び図18、図18、図20に示す通り、基礎土36の上に造成した基礎コンクリート23の上側に、間隔をあけて対向させた長手方向型枠1を長手方向に連続させると共に、この間隔を適宜距離に仕切って区画し、この区画内にコンクリートを打込んで基礎コンクリート23の上に略水平面のL型ブロック基礎台7を造成する。次に、この打込んだコンクリートの凝固する前に、その上側に配置した上面型枠4に追加コンクリート22を充填する事により、図4に示す通り、L型ブロック基礎台7の上面に、据付ける擁壁用L型ブロック3の垂直壁底面に設けたブロック側嵌合構造と合致して嵌合する、基礎側嵌合構造を構成する事ができ、る壁構築の基礎施工法及び完工した基礎構造である。図1、図2、図3の上面型枠4は突起用型枠であり、図4に示すブロック側嵌合構造はLコン嵌合凹部12であり、基礎側嵌合構造は嵌合突起25である。  As shown in FIGS. 1, 2, 3 and 18, 18 and 20, the present invention is a longitudinal type in which the upper side of the foundation concrete 23 formed on the foundation soil 36 is opposed to each other with a space therebetween. The frame 1 is made continuous in the longitudinal direction, and the interval is divided into an appropriate distance, and concrete is poured into the compartment to form an L-shaped block base 7 having a substantially horizontal plane on the foundation concrete 23. Next, before the poured concrete is solidified, an additional concrete 22 is filled into the upper surface mold 4 arranged on the upper side thereof, so that the concrete is placed on the upper surface of the L-shaped block base 7 as shown in FIG. A foundation side fitting structure that fits and fits with the block side fitting structure provided on the bottom surface of the vertical wall of the retaining wall L-shaped block 3 can be constructed. The basic structure. 1, 2, and 3 are projection molds, the block-side fitting structure shown in FIG. 4 is an L-concave recess 12, and the base-side fitting structure is a fitting protrusion 25. It is.

本発明により完工した基礎構造には、図5に示す通り、L型ブロック基礎台7の上に擁壁用L型ブロック3を据付けて、垂直壁底面に設けたLコン嵌合凹部12にL型ブロック基礎台7の嵌合突起25を嵌入して連結し固定する。本発明による擁壁用L型ブロック3は、図6にも示す通り、底面にブロック側嵌合構造を設けた垂直壁8と、この垂直壁に105度の角度で連結されコンクリート充填孔10を設けた底板9と、垂直壁8と底板9に連結する支持部11により構成される。擁壁用L型ブロック3は、L型ブロック基礎台7に据付けて固定した後、底板9のコンクリート充填孔10から基礎コンクリート23と底板9の間にコンクリートを充填し、基礎を堅固に構築した後、擁壁用L型ブロック3の背面側(底板側)は垂直壁8の上端まで埋め土24して上段地表13を造成し、前面側は根元部分を埋めて下段地表14を造成する。  As shown in FIG. 5, the foundation structure completed according to the present invention has an L-shaped block 3 for retaining walls installed on an L-shaped block base 7 and an L-concave recess 12 provided on the bottom of the vertical wall. The fitting protrusion 25 of the mold block base 7 is inserted and connected and fixed.

Therefore, it may be necessary to fix the vertical wall 8 in an inclined state corresponding to the height of the retaining wall to be constructed. Corresponding to such a case, the request | requirement of comprising the upper surface of the L-shaped block base 7 in an inclined surface arises. FIG. 21 shows an embodiment of the L-type block foundation 7 corresponding to such a requirement. The upper surface of the L-type block foundation 7 on the foundation concrete 23 is formed in two longitudinal directions in which the lower stage is formed as an inclined surface. It is a perspective view of the Example which fixes in the state which comprised in the level | step difference and inclined the L-shaped block for retaining walls installed in a lower level | step difference. Therefore, in order to form the lower stage on an inclined surface, it is convenient to use a mold having a flat plate as an inclined plate.
