縦孔11の内径は支持杭２より大径に設定してある。 The inner diameter of the vertical hole 11 is set to be larger than the diameter of the support pile 2.
縦孔11の内周には環状シール12がブラケット13を介し
て上下方向に二組設置してある。Two sets of annular seals 12 are provided on the inner periphery of the vertical hole 11 via a bracket 13 in the vertical direction.
環状シール12の内径は支持杭２の外形とほぼ等しいか
若干小径に設定してある。The inner diameter of the annular seal 12 is set substantially equal to or slightly smaller than the outer shape of the support pile 2.
さらに、一対の環状シール12と支持杭２の周面で区画
される環状空間３に連通して供給管14と排出管15の一端
が案内され、両管14、15の他端が水上または函体１内へ
案内されている。Further, one end of the supply pipe 14 and one end of the discharge pipe 15 are guided by communicating with the pair of annular seals 12 and the annular space 3 defined by the peripheral surface of the support pile 2, and the other ends of both pipes 14, 15 are placed on water or in a box. Guided into body 1.
供給管14は水上から環状空間３へ膨脹材４を供給する
ためのパイプで、また排出管15は排水と膨脹材４の充填
を確認するためのパイプである。The supply pipe 14 is a pipe for supplying the expansion material 4 from above the water to the annular space 3, and the discharge pipe 15 is a pipe for confirming drainage and filling of the expansion material 4.
尚、図面では函体１の浮沈を制御する給水手段や排水
手段を省略してあるが、必要に応じて装備するものとす
る。In the drawings, water supply means and drainage means for controlling the floating and sinking of the box 1 are omitted, but they are provided as necessary.
〈ロ〉支持杭 支持杭２は既設のコンクリート杭、鋼管杭或は場所打
ち杭を含み、その施工法は従来と同様である。<B> Support pile The support pile 2 includes an existing concrete pile, steel pipe pile, or cast-in-place pile, and its construction method is the same as the conventional method.
〈ハ〉膨脹材 膨脹材４としては生石灰を主剤とする膨脹剤または膨
脹セメントなどを使用できる。<C> Expanding material As the expanding material 4, an expanding agent mainly containing quicklime or an expanding cement can be used.
〈作用〉 つぎに第１図を基に支持杭と函体の剛結方法について
説明する。<Operation> Next, a method for rigidly connecting the support pile and the box will be described with reference to FIG.
〈イ〉 函体の沈設 陸上で製作した函体１を現場まで曳航し、函体１を水
底５に着底する。<A> Settlement of the box The box 1 manufactured on land is towed to the site, and the box 1 is landed on the water bottom 5.
函体１を沈設するには、函体１内に注水する等公知の
沈設方法により行う。The box 1 is laid down by a known laying method such as pouring water into the box 1.
〈ロ〉支持杭の構築 函体１の縦孔11をガイドに利用して水底５の支持層に
到達するまで支持杭２を構築する。<B> Construction of support pile The support pile 2 is constructed using the vertical hole 11 of the box 1 as a guide until the pile reaches the support layer of the water bottom 5.
これにより、縦孔11と支持杭２の周面間に環状シール
12で区画された密封構造の環状空間３が画成される。Thereby, an annular seal is formed between the vertical hole 11 and the peripheral surface of the support pile 2.
An annular space 3 having a sealed structure defined by 12 is defined.
〈ハ〉支持杭と函体の剛結 縦孔11内に支持杭２を内挿しただけでは両者１、２は
連結されない。<C> Rigid connection between the support pile and the box By simply inserting the support pile 2 into the vertical hole 11, the two are not connected.
そこで、各供給管14の基端から環状空間３内へ膨脹材
４を充填する。Then, the expansion material 4 is filled into the annular space 3 from the base end of each supply pipe 14.
環状空間３は上下を環状シール12で閉鎖してあるか
ら、干渉シール12と支持杭２の周面間からの漏出が規制
されている。Since the annular space 3 is closed at the top and bottom with the annular seal 12, leakage from between the interference seal 12 and the peripheral surface of the support pile 2 is restricted.
したがって、膨脹材４が環状空間３内の全域に充填さ
れる。Therefore, the expansion material 4 is filled in the entire area in the annular space 3.
環状空間３内の水は排出管15から排水される。 The water in the annular space 3 is drained from the discharge pipe 15.
排出管15から充填材４が漏出するのを確認したら、供
給管14による膨脹材４の供給を停止する。When it is confirmed that the filler 4 leaks from the discharge pipe 15, the supply of the expansion material 4 by the supply pipe 14 is stopped.
その結果、膨脹材４の膨脹圧が環状空間３を画成する
支持杭２と縦孔11の内周面に向けて作用する。As a result, the expansion pressure of the expansion material 4 acts on the support pile 2 and the inner peripheral surface of the vertical hole 11 that define the annular space 3.
函体１と支持杭２はこの膨脹材４の膨脹圧により一体
に剛結される。The box 1 and the support pile 2 are rigidly connected together by the expansion pressure of the expansion material 4.
〈その他の実施例〉 前記実施例は函体全部を水没する場合について説明し
たが、函体１の上部が水上から露出する場合についても
適用できることは勿論である。<Other Embodiments> Although the above embodiment has been described in connection with the case where the entire case is submerged, it is needless to say that the present invention can be applied to a case where the upper part of the case 1 is exposed from the water.
また、環状空間３を画成する上位の環状シール12を縦
孔11の上位に設けて膨脹材４の受圧面積を増大すれば、
より強固に剛結することができる。If the upper annular seal 12 defining the annular space 3 is provided above the vertical hole 11 to increase the pressure receiving area of the expansion member 4,
It can be more firmly connected.
〈発明の効果〉 本発明は以上説明したようになるから次の効果が得ら
れる。<Effects of the Invention> Since the present invention has been described above, the following effects can be obtained.
〈イ〉 函体と支持杭の周面間に形成した環状空間内へ
膨脹材を注入するだけで、両者を早期に剛結することが
できる。<A> By simply injecting the inflating material into the annular space formed between the box and the peripheral surface of the support pile, the two can be quickly and firmly connected.
したがって作業の簡素化と作業時間の短縮が図れる。 Therefore, the operation can be simplified and the operation time can be reduced.
〈ロ〉 支持杭の断面形状や縦孔の断面形状に制限を受
けずに施工できる。<B> Construction can be performed without any restrictions on the cross-sectional shape of the support pile or the vertical hole.
