この発明は、構造物の基礎工法、更に詳しくは擁壁の如
きコンクリート構造物を基礎杭によって支持する構造物
の基礎工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a foundation construction method for a structure, and more particularly to a foundation construction method for a structure in which a concrete structure such as a retaining wall is supported by foundation piles.
例えば１９壁の如き土留構造物の基礎構造は、構造物を
構築する地盤に基礎杭を打設し、構造物をこの基礎杭に
よって支持するようになっている。For example, the foundation structure of an earth retaining structure such as 19-wall is such that foundation piles are driven into the ground on which the structure is built, and the structure is supported by the foundation piles.
従来、上記基礎杭は、構造物に作用する外力、自重等を
すべて杭で負担するものとして設計され、従って安定性
を良（するため基礎杭は２列以上を打設し、またクラッ
ク等の防止のため、杭頭部は剛結合して杭頭モーメント
に抵抗できる構造が採用されている。Conventionally, the foundation piles mentioned above were designed to bear all the external forces acting on the structure, their own weight, etc., and therefore had good stability. To prevent this, a structure is adopted in which the pile head is rigidly connected to resist the pile head moment.
ところで、上記のような従来の基礎構造は、使用する杭
の本数が非常に多くなり、工費についても基礎工事の占
める割合が大きくなるという問題がある。However, in the conventional foundation structure as described above, there is a problem in that the number of piles used is extremely large, and the proportion of the construction cost for the foundation work is also large.
この発明の課題は、上記のような問題点を解決するため
、構造物の安定を損なうことなく基礎杭の規模を小さ（
することができ、工期の短縮とコストダウンを図ること
ができる構造物の基礎工法を提供することにある。The purpose of this invention is to reduce the size of foundation piles without compromising the stability of the structure, in order to solve the above problems.
The object of the present invention is to provide a foundation construction method for structures that can shorten the construction period and reduce costs.
上記のような課題を解決するため、この発明は構造物の
長手方向に基礎杭を一列に設け、各杭頭と構造物の取付
は部をヒンジ構造とする構成としたものである。In order to solve the above-mentioned problems, the present invention provides a structure in which foundation piles are provided in a row in the longitudinal direction of a structure, and each pile cap and the structure are attached using a hinge structure.
構造物を構築する地盤に対して基礎杭を、構造物の長手
方向に沿って、しかも地盤の低い側の位置に一列の配置
で打設し、構築した構造物と各杭頭をヒンジ構造で結合
して構造物を支持すると、構造物は地盤の高い側にもた
れる状態となって安定し、また構造物の底版下面には地
盤反力を生じ、基礎杭の鉛直荷重の負担を軽減する。The foundation piles are driven into the ground where the structure will be built in a row along the length of the structure and at the lower side of the ground. When the structure is connected and supported, the structure rests against the higher side of the ground, making it stable, and also generates a ground reaction force on the bottom of the structure's bottom slab, reducing the vertical load on the foundation piles.
以下、この発明の実施例を添付図面に基づいて説明する
。Embodiments of the present invention will be described below with reference to the accompanying drawings.
図示のように、地盤１上に構築される構造物２は、盛土
３や切土などを土留する擁壁であり、底版４上に支持壁
５を立設したコンクリート構造になっている。As shown in the figure, the structure 2 built on the ground 1 is a retaining wall for retaining embankment 3, cut earth, etc., and has a concrete structure in which a support wall 5 is erected on a bottom slab 4.
上記構造物２を支持するため地盤１に打設した基礎杭６
は、地盤１の低い側の位置において、構造物２の長手方
向に沿って一列に配置されている。Foundation piles 6 driven into the ground 1 to support the structure 2 above
are arranged in a line along the longitudinal direction of the structure 2 at a position on the lower side of the ground 1.
従って、各基礎杭６の杭頭は、構造物２の底版４の直下
において、支持壁５寄りの下部を支持するように配置さ
れ、各杭頭と構造物２の取付は部分がヒンジ構造７によ
って結合されている。Therefore, the pile cap of each foundation pile 6 is arranged directly under the bottom slab 4 of the structure 2 so as to support the lower part near the support wall 5, and the attachment of each pile cap and the structure 2 is partially hinged to the hinge structure 7. are connected by.
上記ヒンジ構造７は、種々の構造を採用することができ
、図面はそのいくつかの例を示している。The hinge structure 7 can adopt various structures, and the drawings show some examples thereof.
第１図に示ずヒンジ構造７の第１の例は、構造物２の長
手方向と直角の方向に折れ曲がりが可能となるジヨイン
ト８を用いている。A first example of the hinge structure 7, not shown in FIG. 1, uses a joint 8 that can be bent in a direction perpendicular to the longitudinal direction of the structure 2.
第２図に示す第２の例は、構造物２の底版４における下
面に突起Ｓを設け、底版４と突起９のコーナ部分に当て
仮１０を介して杭頭の上端を当接させた構造になってい
る。The second example shown in FIG. 2 is a structure in which a protrusion S is provided on the lower surface of the bottom plate 4 of the structure 2, and the upper end of the pile head is brought into contact with the corner portion of the bottom plate 4 and the protrusion 9 via a temporary contact 10. It has become.
第３図に示す第３ の例は、基礎杭６の頭部を球頭部６
ａに形成し、底版４の下面に球状凹部１１を設け、当て
板１２を介して上記球頭部６ａを球状凹部１１に嵌合さ
せた構造になっている。In the third example shown in Fig. 3, the head of the foundation pile 6 is replaced with a ball head 6.
a, a spherical recess 11 is provided on the lower surface of the bottom plate 4, and the spherical head 6a is fitted into the spherical recess 11 via a backing plate 12.
第４図に示す第４の例は、杭頭と構造物２を鉄筋（メナ
ーゼヒンジ）１３で結合した構造を示している。The fourth example shown in FIG. 4 shows a structure in which the pile cap and the structure 2 are connected by reinforcing bars (menase hinge) 13.
このように、ヒンジ構造７は、ヒンジの役割を果すもの
であればよく、例えば基礎杭６の上端に構造物２を載せ
るだけでもよい。In this way, the hinge structure 7 may be any structure as long as it plays the role of a hinge, and for example, the structure 2 may simply be placed on the upper end of the foundation pile 6.
一列に打設した基礎杭６によって支持された構造物２は
、ヒンジ構造７によって地盤１の低い側が支点になり、
構造物２は地盤１の高い側にもたれる状態となって安定
し、盛土３や切土などの土を支える。The structure 2 supported by the foundation piles 6 driven in a row has the low side of the ground 1 as a fulcrum by the hinge structure 7,
The structure 2 is stabilized by leaning against the higher side of the ground 1, and supports the earth such as the embankment 3 and cut earth.
これによって、構造物２の底版４の下面に地盤反力を生
じ、基礎杭６に作用する鉛直荷重の負担を軽減すること
ができる。Thereby, a ground reaction force is generated on the lower surface of the bottom slab 4 of the structure 2, and the burden of the vertical load acting on the foundation pile 6 can be reduced.
以上のように、この発明によると、基礎杭とその上に構
築した構造物との取付部分をヒンジ構造としたので、土
圧を受ける構造物の底版下面がヒンジ構造を支点として
地盤に圧着し、底版下面に地盤反力を生じ、基礎杭に作
用する鉛直荷重が軽減され、基礎構造の規模が小さくで
きる。As described above, according to the present invention, since the attachment part between the foundation pile and the structure built thereon is a hinge structure, the lower surface of the bottom slab of the structure that is subjected to earth pressure is pressed to the ground using the hinge structure as a fulcrum. , a ground reaction force is generated on the bottom surface of the bottom slab, the vertical load acting on the foundation pile is reduced, and the scale of the foundation structure can be reduced.
また、基礎杭を一列に打設して配置するので測量が容易
となり、杭木数の削減により、コストダウン及び工期短
縮が図れる。Additionally, since the foundation piles are driven and arranged in a row, surveying becomes easier, and by reducing the number of piles, it is possible to reduce costs and shorten the construction period.
