Description

本発明は杭体とプレキャスト版との接合方法に関する。   The present invention relates to a method for joining a pile body and a precast plate.

各種コンクリート構造物の安定化手段として杭体が用いられている。杭体を用いて上部構造物の安定化を図るためには、杭体と上部構造物とを接合する必要がある。
杭体と上部構造物との接合には、杭体の設置後、この杭体の杭頭が埋め込まれるように、上部構造物の底版等を場所打ちコンクリートにて形成するといった方法が広く採用されているが(例えば特許文献1参照)、このような接合方法にあっては、型枠の組付け、コンクリートの打設及び養生、型枠の脱型など、現場での作業工程が多くなることから、工期が長くなりやすい。
このため、現場での工程を少なく抑えるために、プレキャスト化した底版等が用いられている。そして、このようなプレキャスト版を、先行して杭体を設置した後に、杭体の杭頭と係合するように敷設する方法が提案されている。
あるいは、図18に示すように、プレキャスト版Aに貫通孔Bを設けておき、プレキャスト版Aの敷設後に、杭体Cを貫通孔B内に貫通させて設置し、杭体Cの杭頭を位置させた貫通孔B内にモルタル等の固結材Dを充填するといった方法も提案されている。
Pile bodies are used as a means for stabilizing various concrete structures. In order to stabilize the upper structure using the pile body, it is necessary to join the pile body and the upper structure.
For joining the pile body and the upper structure, a method of forming the bottom plate of the upper structure with cast-in-place concrete so that the pile head of this pile body is embedded after the pile body is installed is widely adopted. However, in such a joining method, there are many on-site work processes such as assembling the formwork, placing and curing concrete, and demolding the formwork. Therefore, the construction period tends to be long.
For this reason, in order to reduce the number of on-site processes, a precast bottom plate or the like is used. And the method of laying such a precast version so that it may engage with the pile head of a pile body after installing a pile body in advance is proposed.
Alternatively, as shown in FIG. 18, a through-hole B is provided in the precast plate A, and after laying the precast plate A, the pile body C is installed through the through-hole B, and the pile head of the pile body C is attached. There has also been proposed a method in which a solidified material D such as mortar is filled in the positioned through hole B.

<2>貫通孔に固結材を充填する接合方法にあっては、杭体の押込み及び引抜きに対する接合強度がプレキャスト版と固結材との付着性に大きく依存するため、十分な接合強度を得ることが難しい。

Therefore, extremely high accuracy is required for the pile installation position.
<2> In the joining method in which the through hole is filled with the consolidation material, the bonding strength against the pushing and pulling of the pile body depends greatly on the adhesion between the precast plate and the consolidation material, so that sufficient bonding strength is obtained. Difficult to get.

以下、図面を参照しながら本発明に係る実施の形態について説明する。   Embodiments according to the present invention will be described below with reference to the drawings.

まず、本実施例で使用する主要な資材について説明する。   First, main materials used in this embodiment will be described.

<1>プレキャスト版
プレキャスト版5は、例えばコンクリート材料で工場あるいは現場ヤードにて構築する。
図1に示すように、プレキャスト版5の所定位置、例えば複数の所定位置には、厚さ方向に貫通孔51を設けておくとともに、この貫通孔51の内面には、後述する杭体3の杭頭を嵌装させる杭頭嵌装筒体2を埋め込んでおく。
<1> Precast plate The precast plate 5 is constructed of, for example, a concrete material in a factory or on-site yard.
As shown in FIG. 1, a through hole 51 is provided in a predetermined position of the precast plate 5, for example, a plurality of predetermined positions, in the thickness direction, and a pile body 3 to be described later is formed on the inner surface of the through hole 51. The pile head fitting cylinder 2 in which the pile head is fitted is embedded.

<2>杭頭嵌装筒体
杭頭嵌装筒体2は、杭体3を設置する際に、杭頭を包囲するように嵌装させるものである。杭頭嵌装筒体2は、軸方向両端または軸方向両端部がそれぞれ開放した、直線状に延びる筒状の側板23を備えている。すなわち、側板23は、軸方向に貫通する筒状に形成してなる。
側板23の内面及び外面には、複数の突起部21を杭頭嵌装筒体軸方向に間隔をもって設置する。この場合には、内面または外面に全周にわたって突起部21を設けることもでき、また、内面または外面に周方向に間隔をもって突起部21を設けることもできる。側板23の内面に突起部21を設ける目的は、後述する固結材4の硬化体を、貫通孔51または杭頭嵌装筒体2の軸方向に拘束して杭頭嵌装筒体2から容易に引き抜けないようにするためである。特に、軸方向両端の開放端部26にそれぞれ、突起部21を設けて、開放端部26を狭くすることが効果的である。また、側板23の外面に突起部21を設ける目的は、杭頭嵌装筒体2がプレキャスト版5から容易に引き抜けないようにするためである。
杭頭嵌装筒体2の内空断面は、軸方向両側から杭体3を挿入できるように、杭体3の直径に対して余裕をもたせた大きさとしておくのが好ましい。
杭頭嵌装筒体2のプレキャスト版5への埋込み長は、杭頭の構造や杭径などに合わせて、任意に設定することができるが、固結材4のプレキャスト版5との付着性を考慮すると、杭頭嵌装筒体2を、プレキャスト版5の貫通孔51の軸方向中心部に埋め込むことが好ましい。
杭頭嵌装筒体2の材質は、例えば、鋼材やセラミック、鋳鉄などにより製作することができる。
なお、筒体を構成する側板23は、円筒のほか、多角形の筒などに形成することができる。
<2> Pile head fitting cylinder body The pile head fitting cylinder body 2 is fitted so as to surround the pile head when the pile body 3 is installed. The pile head fitting cylinder 2 is provided with a cylindrical side plate 23 that extends in a straight line with both axial ends or both axial ends open. That is, the side plate 23 is formed in a cylindrical shape penetrating in the axial direction.
On the inner surface and outer surface of the side plate 23, a plurality of projections 21 are installed at intervals in the axial direction of the pile head fitting cylinder. In this case, the protrusions 21 can be provided over the entire circumference on the inner surface or the outer surface, and the protrusions 21 can be provided on the inner surface or the outer surface at intervals in the circumferential direction. The purpose of providing the protrusions 21 on the inner surface of the side plate 23 is to restrain the hardened body of the caking material 4 described later from the pile head fitting cylinder 2 by restraining the cured body 4 in the axial direction of the through hole 51 or the pile head fitting cylinder 2. This is to prevent it from being pulled out easily. In particular, it is effective to provide the protrusions 21 at the open ends 26 at both ends in the axial direction to narrow the open ends 26. The purpose of providing the protrusion 21 on the outer surface of the side plate 23 is to prevent the pile head fitting cylinder 2 from being easily pulled out from the precast plate 5.
It is preferable that the hollow section of the pile head fitting cylinder 2 has a size with a margin with respect to the diameter of the pile body 3 so that the pile body 3 can be inserted from both sides in the axial direction.
The embedding length of the pile head fitting cylinder 2 in the precast plate 5 can be arbitrarily set according to the structure of the pile head, the pile diameter, etc., but the adhesion of the consolidated material 4 to the precast plate 5 In consideration of the above, it is preferable to embed the pile head fitting cylinder 2 in the central portion in the axial direction of the through hole 51 of the precast plate 5.
The material of the pile head fitting cylinder 2 can be manufactured by, for example, steel, ceramic, cast iron, or the like.
In addition, the side plate 23 which comprises a cylinder can be formed in a polygonal cylinder other than a cylinder.

<3>杭体
本発明の杭体とプレキャスト版との接合方法に用いられる杭体3としては、30cm以下の小口径の場所打ち杭や埋め込み杭などのマイクロパイル、鋼管杭やPHC杭などの既製杭、場所打ちコンクリート杭などがある。また、斜面の補強工事などにおいて使用するモルタルと鉄筋などの芯材からなる小口径杭、または地盤を改良したソイルセメントの中に鋼材などを挿入する補強柱体などもある。
杭体3の杭頭には、表面にネジ溝部31を設けることができる。かかるネジ溝部31を設ける目的は、杭体3を後述する硬化後の固結材4から抜け出難くするためである。また、かかる抜け出し防止効果をさらに向上させるために、複数の中空枠32を杭頭に嵌装させた構造を使用することもできる。中空枠32の突出部が杭体軸方向の引抜き力に対して支圧板としての効果を発揮することとなり、杭体3が硬化後の固結材4からさらに抜け出難くなる。
<3> Pile body As the pile body 3 used for the method of joining the pile body of the present invention and the precast plate, a micropile such as a cast-in-place pile or embedded pile with a small diameter of 30 cm or less, a steel pipe pile, a PHC pile, etc. There are ready-made piles and cast-in-place concrete piles. There are also small-diameter piles made of core material such as mortar and reinforcing bars used in slope reinforcement work, or reinforcing columns that insert steel materials into soil cement with improved ground.
A screw groove portion 31 can be provided on the surface of the pile head of the pile body 3. The purpose of providing the thread groove 31 is to make it difficult for the pile body 3 to come out of the hardened consolidated material 4 described later. Moreover, in order to further improve the pull-out prevention effect, a structure in which a plurality of hollow frames 32 are fitted to the pile head can be used. The protruding portion of the hollow frame 32 exhibits an effect as a pressure bearing plate against the pulling force in the pile body axial direction, and the pile body 3 is more difficult to come out of the consolidated material 4 after curing.

<4>固結材
固結材4は、プレキャスト版5に埋め込まれた杭頭嵌装筒体2に杭頭を嵌装させた後に、貫通孔51内、より具体的には、貫通孔51及び杭頭嵌装筒体2と杭頭とに囲まれた空間に充填させるものである(図2参照)。充填された固結材4は、貫通孔51の内面、杭頭嵌装筒体2の内面及び杭頭の外面と密着することとなる。そして、固結材4が硬化すると、杭頭嵌装筒体2が硬化した固結材4を軸方向に拘束し、硬化した固結材4が杭体3または杭頭を軸方向に拘束するので、固結材4と杭頭、固結材4と杭頭嵌装筒体2、および固結材4とプレキャスト版5が夫々連結されて、杭体3とプレキャスト版5との一体化を図ることができる。すなわち、この際に、杭頭嵌装筒体2と硬化後の固結材4とは、杭体3及びプレキャスト版5を強固に接合するための楔構造体を構成する。
固結材4としては、セメントグラウト材や無収縮グラウト材、膨張性高強度グラウト材、樹脂系グラウト材などを使用することができる。
<4> Consolidating material The consolidating material 4 is formed in the through hole 51, more specifically, the through hole 51 after the pile head is fitted to the pile head fitting cylinder 2 embedded in the precast plate 5. And the space surrounded by the pile head fitting cylinder 2 and the pile head is filled (see FIG. 2). The filled consolidated material 4 comes into close contact with the inner surface of the through hole 51, the inner surface of the pile head fitting cylinder 2, and the outer surface of the pile head. And when the consolidated material 4 hardens | cures, the solidified material 4 which the pile head fitting cylinder 2 hardened will restrain in an axial direction, and the hardened consolidated material 4 will restrain a pile body 3 or a pile head in an axial direction. Therefore, the consolidated material 4 and the pile head, the consolidated material 4 and the pile head fitting cylinder 2, and the consolidated material 4 and the precast plate 5 are respectively connected, and the pile body 3 and the precast plate 5 are integrated. Can be planned. That is, at this time, the pile head fitting cylinder 2 and the hardened consolidated material 4 constitute a wedge structure for firmly joining the pile 3 and the precast plate 5.
As the consolidated material 4, a cement grout material, a non-shrinkable grout material, an expandable high-strength grout material, a resin grout material, or the like can be used.

<5>用途
本実施例では、プレキャスト版5がボックスカルバート等の箱状の埋設函5aであり、杭体3が埋設函5aの基礎杭3aである場合について説明する。
<5> Application In this embodiment, a case where the precast plate 5 is a box-like buried box 5a such as a box culvert and the pile body 3 is a foundation pile 3a of the buried box 5a will be described.

<6>基礎杭と埋設函との接合方法(図3、4)
[埋設函の敷設]
まず、地中に一対の山留壁61、61を設け、この山留壁61、61間の地盤に掘削溝62を形成する。
次に、掘削溝62の底部に基礎部63を設ける。基礎部63は、例えばコンクリート製とすることができる。
続いて、基礎部63上に分割した埋設函5a1を敷設する。埋設函5a1の底部には前述の貫通孔51を設けておく。
[基礎杭の設置]
埋設函5a1の敷設後、この埋設函5a1の底部上に基礎杭3aを設置するための作業機械64、例えば杭打ち機械を配備する。
そして、作業機械64によって、基礎杭3aを、貫通孔51及び基礎部63を貫通させ、地中に打ち込んで、あるいは構築して設置する。この際に、杭頭を杭頭嵌装筒体2に包囲させて嵌装させる(図2参照、図3、4では省略)。
[固結材の充填]
基礎杭3aの設置後、埋設函5a1の底部のそれぞれの貫通孔51内に固結材4を充填する。充填された固結材4が硬化することにより楔構造体が構成され、基礎杭3aと埋設函5a1とが接合される。
[後処理]
最後に、埋設函5a1上に分割した他方の埋設函5a2を固定設置して埋設函5aを構築する。
なお、掘削溝62を埋め戻すとともに、山留壁61、61を取り除く。
[作用・効果]
底版5aの敷設後に、貫通孔51をガイド孔として利用して基礎杭3aを設置するので、基礎杭3aを確実に所定位置に設置することができる。
杭頭嵌装筒体2の内面に突起部21を設けておくことにより、貫通孔51に充填した固結材4の硬化体を軸方向に拘束することができる。また、基礎杭3の杭頭の外周にネジ溝部31及び中空枠32を設けておくことにより、固結材4の硬化体が基礎杭3を軸方向に拘束することができる。したがって、基礎杭3aと底版5aとが強固に接合される。
基礎杭3を設置するための作業機械64を底版5a上に配備できるため、掘削溝62の幅を、埋設函5aが入る必要最小限に設定することができる。すなわち、施工の効率化を図れる。

実施例1乃至6において、杭頭嵌装筒体2を構成する側板23の形状を、図13に示すように、円筒や多角形の筒であって、側板23の軸方向両側の内空断面をそれぞれ、軸方向中間部27側から開放端部26に向かって漸次縮小するように形成することができる。すなわち、軸方向両側または開放端部26の内空断面を、軸方向中間部27の内空断面よりも小さく形成することができる。このように構成することにより、貫通孔51内に固結材4を充填した際に、側板23の内面に密着した固結材4の硬化体が杭頭嵌装筒体2から抜け出難くなるとともに、杭体3に軸方向の引抜き力または押込み力が加わった際に、楔効果による固結材4の硬化体の締め付け力を杭頭に作用させ、杭頭の軸方向の拘束を図ることができる。かかる側板形状の筒体においても、側板23の外面、特に軸方向両端部の外面に突起部21を設けることができる。
なお、側板23の軸方向両側の内空断面をそれぞれ、軸方向中間部27側から開放端部26に向かって漸次拡大するように形成しても、同様の効果を得ることが可能である。
すなわち、側板23を、軸方向両端部の内空断面と軸方向中間部の内空断面とが異なる大きさとなるように形成することができる。
さらに、図14に示すように、杭頭嵌装筒体2の内面に突起部21を設ける構成を組み合わせてもよい。かかる構造の目的は、固結材4の硬化体を杭頭嵌装筒体2からより抜け出難くするためである。
In Example 1 thru | or 6, as shown in FIG. 13, the shape of the side plate 23 which comprises the pile head fitting cylinder 2 is a cylinder or a polygonal cylinder, Comprising: The hollow cross section of the axial direction both sides of the side plate 23 Can be formed so as to be gradually reduced from the axial intermediate portion 27 side toward the open end portion 26. That is, the inner air cross section of the both axial sides or the open end portion 26 can be formed smaller than the inner air cross section of the axial intermediate portion 27. By configuring in this way, when the consolidated material 4 is filled in the through-hole 51, the hardened body of the consolidated material 4 that is in close contact with the inner surface of the side plate 23 becomes difficult to come out of the pile head fitting cylinder 2. When the pulling force or pushing force in the axial direction is applied to the pile body 3, the tightening force of the hardened body of the consolidated material 4 due to the wedge effect is applied to the pile head to restrain the pile head in the axial direction. it can. Also in such a side plate-shaped cylinder, the protrusions 21 can be provided on the outer surface of the side plate 23, particularly on the outer surfaces of both axial end portions.
The same effect can be obtained by forming the inner air cross sections on both sides in the axial direction of the side plate 23 so as to gradually expand from the axial intermediate portion 27 side toward the open end portion 26.
That is, the side plate 23 can be formed so that the inner hollow cross section at both axial end portions and the inner hollow cross section at the axial intermediate portion have different sizes.
Furthermore, you may combine the structure which provides the projection part 21 in the inner surface of the pile head fitting cylinder 2 as shown in FIG. The purpose of this structure is to make it harder for the hardened body of the consolidated material 4 to come out of the pile head fitting cylinder 2.

前述した接合形態以外に、図15に示すような形態で接合してもよい。すなわち、本実施例では、先行して杭体3を設置し、杭体3の杭頭にプレキャスト版5の底面側に設けた挿通孔52を挿通させて、このプレキャスト版5を敷設する。挿通孔52内には、杭頭嵌装筒体2を埋め込んでおくことができるが(図示せず)、杭頭嵌装筒体2は、上側開口を閉塞した構造とすることができる。
そして、挿通孔52内、より具体的には杭頭嵌装筒体2内に固結材4を充填することにより、杭体3とプレキャスト版5とを接合する。固結材4を充填にあたっては、杭頭嵌装筒体2の壁面に注入孔を設けておくとともに、この注入孔と連通して上面側に抜ける注入通路をプレキャスト版5内に設けておき、注入通路への注入によって行うことができる(図示せず)。
このような接合方法は、山岳部等の斜面に設けた道路71を拡幅する場合(図16参照)や道路71にロックシェッド72を構築する場合(図17参照)などに適用できる。
In addition to the joining form described above, joining may be performed in a form as shown in FIG. That is, in this embodiment, the pile body 3 is installed in advance, the insertion hole 52 provided on the bottom surface side of the precast plate 5 is inserted into the pile head of the pile body 3, and the precast plate 5 is laid. Although the pile head fitting cylinder 2 can be embedded in the insertion hole 52 (not shown), the pile head fitting cylinder 2 can have a structure in which the upper opening is closed.
Then, the pile body 3 and the precast plate 5 are joined by filling the solidified material 4 in the insertion hole 52, more specifically, the pile head fitting cylinder 2. In filling the consolidated material 4, an injection hole is provided in the wall surface of the pile head fitting cylinder 2, and an injection passage communicating with the injection hole and exiting to the upper surface side is provided in the precast plate 5. This can be done by injection into the injection passage (not shown).
