Description

本発明は、大型のタンクを建設するときに打ち込まれる増し杭の杭頭とスラブとの接合に係る杭接合構造に関する。   The present invention relates to a pile joint structure relating to joining of a pile head of an additional pile to be driven when constructing a large tank and a slab.

従来、LNG等の低温液体を貯留する大型のタンクの設置される地盤には、互いに所定の間隔を保って複数本の基礎杭が打ち込まれる。
そして、それら打ち込まれた基礎杭の杭頭は、タンクの底部分に当るスラブと剛結により接合されるように構成されている。
Conventionally, a plurality of foundation piles are driven into a ground where a large tank for storing a low-temperature liquid such as LNG is installed at a predetermined interval.
The pile heads of the foundation piles that have been driven are configured to be joined to the slab that hits the bottom portion of the tank by rigid connection.

上述の基礎杭は、タンクの周辺部分はその周方向に沿って所定の間隔を保って配置され、タンクの中心部分は碁盤目状を呈するように配置されている。そして、基礎杭の総本数は、タンクの大きさにもよるが、タンクの直径が100メートルにも及ぶような場合は数百本にも及んでいる。   As for the above-mentioned foundation pile, the peripheral part of a tank is arranged at predetermined intervals along the circumferential direction, and the central part of the tank is arranged so as to exhibit a grid pattern. And the total number of foundation piles depends on the size of the tank, but when the diameter of the tank reaches 100 meters, it reaches several hundred.

基礎杭の本数が数百本にも及ぶような場合、打ち込み不調の基礎杭が発生するが、この場合は、その打ち込み不調の基礎杭の周囲に増し杭と呼ばれる新たな基礎杭が打ち込まれる。この増し杭の杭頭とスラブとの接合も、他の正常な基礎杭と同様に剛結構造が採用されている。   When the number of foundation piles reaches several hundred, a foundation pile with poor driving is generated. In this case, a new foundation pile called an additional pile is driven around the foundation pile with poor driving. As with other normal foundation piles, the rigid pile structure is also used for joining the pile head of the additional pile and the slab.

しかしながら、上記従来の増し杭の杭頭とスラブとの接合に係る杭接合構造は、他の正常な基礎杭と同様に剛結構造が採用されているので、配筋作業が複雑となるばかりでなく、配筋作業に長時間要し、コスト高になる欠点があった。   However, the pile connection structure related to the connection between the pile head of the conventional additional pile and the slab has a rigid connection structure as well as other normal foundation piles. In addition, there is a drawback in that the bar arrangement work takes a long time and the cost is high.

特に、増し杭の設置箇所がタンクの周辺部分に位置するときは、その欠点が顕著であった。なぜならば、増し杭の設置箇所がタンクの周辺部分の場合、その周辺部分の配筋状態は、周辺方向の配筋とタンクの中心部分の配筋とが複雑に交差している状態にあり、さらに増し杭の配筋を行うことに困難を伴うからである。   In particular, when the location where the additional pile is installed is located in the peripheral portion of the tank, the drawbacks are remarkable. This is because when the additional pile is installed in the peripheral part of the tank, the bar arrangement in the peripheral part is in a state where the bar arrangement in the peripheral direction and the bar arrangement in the central part of the tank intersect in a complex manner. This is because it is difficult to arrange additional piles.

本発明は、上述する問題点に鑑みてなされたもので、増し杭が打ち込まれても、その増し杭の杭頭とスラブとを簡単に接合することのできる杭接合構造を提供することを目的とする。   The present invention has been made in view of the above-described problems, and an object thereof is to provide a pile joint structure that can easily join the pile head of the additional pile and the slab even if the additional pile is driven. And

本発明に係る杭接合構造は、上記課題を解決するための手段として、以下の構成を採用する。   The pile joint structure according to the present invention employs the following configuration as means for solving the above-described problems.

第1の発明は、タンクを建設するときに打ち込まれる基礎杭の杭頭とスラブとの接合に係る杭接合構造であって、基礎杭に固定されると共に扁平な上面を有する杭設置部と、スラブに固定されると共に前記杭設置部が有する前記上面と当接される扁平な下面を有するスラブ設置部と、を備えるという構成を採用する。   1st invention is the pile joint structure which concerns on the joint of the pile head and the slab of the foundation pile driven when constructing a tank, Comprising: The pile installation part which has a flat upper surface while being fixed to a foundation pile, A configuration is adopted in which the slab is provided with a slab installation part that is fixed to the slab and has a flat lower surface that comes into contact with the upper surface of the pile installation part.

第2の発明は、上記第1の発明において、前記基礎杭が、基礎杭の打ち込みが不調のときに打ち込まれる増し杭であるという構成を採用する。   2nd invention employ | adopts the structure that the said foundation pile is an additional pile driven in when the driving | operation of a foundation pile is unsatisfactory in the said 1st invention.

第3の発明は、上記第1または第2の発明において、前記杭設置部の前記上面の面積と前記スラブ設置部の前記下面の面積とが、異なるものであるという構成を採用する。   3rd invention employ | adopts the structure that the area of the said upper surface of the said pile installation part and the area of the said lower surface of the said slab installation part differ in the said 1st or 2nd invention.

第4の発明は、上記第1〜第3いずれかの発明において、前記タンクは、液化天然ガス等の流体を貯留するものであるという構成を採用する。   According to a fourth invention, in any one of the first to third inventions, a configuration is adopted in which the tank stores fluid such as liquefied natural gas.

本発明に係る杭接合構造は、基礎杭の杭頭に設けられる杭設置部の上面に、スラブに設けられるスラブ設置部の下面が当接して接合するので、構造が簡単なため施工が容易になり、したがって、低コストに実施することができる。
しかも、本発明に係る杭接合構造は、構造が簡単であるにもかかわらず、スラブに作用する水平変位と曲げモーメントをすべり支承により無害化して鉛直荷重のみを基礎杭に伝達することができる。
また、基礎杭を増し杭としたときは、特に、配筋状態が複雑に錯綜しているタンクの周辺に打ち込まれる増し杭にも容易に適用することができる。
そして、杭設置部の上面の面積及びスラブ設置部の下面の面積が異なるものとしたときは、杭設置部とスラブ設置部との当接をより容易に行うことができる。
さらに、タンクが液化天然ガス等の流体を貯留するものであるときは、液化天然ガス等の流体を貯留する大型のタンクの増し杭に、容易に適用することができる。
In the pile joint structure according to the present invention, the lower surface of the slab installation part provided on the slab is in contact with and joined to the upper surface of the pile installation part provided on the pile head of the foundation pile. Therefore, it can be implemented at low cost.
Moreover, the pile joint structure according to the present invention can transmit only the vertical load to the foundation pile by making the horizontal displacement and bending moment acting on the slab harmless by the sliding support, though the structure is simple.
In addition, when the foundation pile is increased, it can be easily applied to an additional pile driven around the tank where the bar arrangement is complicated.
And when the area of the upper surface of a pile installation part differs from the area of the lower surface of a slab installation part, contact | abutting with a pile installation part and a slab installation part can be performed more easily.
Furthermore, when the tank stores fluid such as liquefied natural gas, it can be easily applied to an additional pile of a large tank that stores fluid such as liquefied natural gas.
