Description
【発明の詳細な説明】 本発明は鋼板セルの打込み工法に関する。[Detailed description of the invention] The present invention relates to a steel plate cell driving method.
従来、円筒形の鋼板セルを製作する際、その形状及び寸
法の保持のために治具を用いて製作し製作が完了すると
この治具を取り外していた。Conventionally, when manufacturing a cylindrical steel plate cell, a jig was used to maintain the shape and dimensions of the cell, and the jig was removed when the manufacturing was completed.
そしてこの鋼板セルを運搬する際は、運搬中における形
状保持のために保形枠を鋼板セルに取りつけて運搬して
いた。When transporting this steel plate cell, a shape-retaining frame was attached to the steel plate cell to maintain its shape during transportation.
そして、この鋼板セルを打込む際には、保形枠を鋼板セ
ルから取り外して、新たに座屈防止用の補強枠を鋼板セ
ルに固定して打込んでいた。When driving this steel plate cell, the shape retaining frame was removed from the steel plate cell, and a new reinforcing frame for preventing buckling was fixed to the steel plate cell and then driven.
従って、従来鋼板セルを打込むには、治具の他に保形枠
を必要とし、かつこれらを取り付けかつ取外すために多
大の手数及び時間を要する不具合があった。Therefore, conventionally, in order to drive steel plate cells, a shape-retaining frame was required in addition to a jig, and there was a problem in that it required a great deal of effort and time to attach and detach these frames.
本発明は、上記不具合を解消するために提案されたもの
で以下、本発明を第１図ないし第６図を参照して具体的
に説明する。The present invention was proposed to solve the above-mentioned problems, and the present invention will be specifically explained below with reference to FIGS. 1 to 6.
第１図ないし第４図は鋼板セルの製作要領を示し、治具
７は円周材２を棒材４によって補強をしてなる２つの枠
５を柱材６により相互に連結して組立てられる。Figures 1 to 4 show the steps for manufacturing a steel plate cell, and a jig 7 is assembled by interconnecting two frames 5 made by reinforcing a circumferential member 2 with a bar 4 and a column 6. .
この治具７の円周材２に沿わせて多数の鋼板１ａを建て
かけてつなぎ板３を介して治具７と固着した後、鋼板１
ａ相互間に溶接８して、鋼板セル１を製作する。After erecting a large number of steel plates 1a along the circumferential material 2 of this jig 7 and fixing them to the jig 7 via the connecting plate 3, the steel plates 1a
A welding 8 is performed between each other to produce a steel plate cell 1.
なお、必要に応じ第４図で示すごとく治具７をそのまま
固着しておいて各鋼板セル１を複数個段重ねとして相互
間を溶接９すればよい。If necessary, the jig 7 may be fixed as is as shown in FIG. 4, and each steel plate cell 1 may be stacked in a plurality of stages and welded 9 between them.
次に、鋼板セル１は、第５″図に示すように、治具７を
固着したままその上部を吊具１１により把みクレーン１
２により吊上げ、台船１３に積み込み打込み場所まで運
ぶ。Next, as shown in FIG.
2, and loaded onto the barge 13 and transported to the driving location.
次に、打込み場所へ鋼板セル１を設置し、治具７を、ク
レーン１２により吊下げた状態でつなぎ板３を切断し治
具７を鋼板セル１から分離する。Next, the steel plate cell 1 is installed at the driving location, and the jig 7 is suspended from the crane 12, and the connecting plate 3 is cut to separate the jig 7 from the steel plate cell 1.
次に、第６図に示すように鋼板セル１内に治具７を吊下
げて維持したまま打込機１４により鋼板セル１の打込み
を行なえば打込みに伴なう鋼板セル１の座屈やオーバル
振動を防止し、打込み能率を向上できる。Next, as shown in FIG. 6, if the steel plate cell 1 is driven by the driving machine 14 while the jig 7 is suspended and maintained within the steel plate cell 1, buckling of the steel plate cell 1 due to driving can be avoided. Prevents oval vibration and improves driving efficiency.
なお、鋼板セル１の下端は海底土に、その上端は吊具１
１によりほぼ拘束状態にあるので打込みに伴なう鋼板セ
ル１の座屈およびオーバル振動は鋼板セル１の中間位置
に多発するので鋼板セル１の上端付近と下端付近に固着
されている治具７は打込み前に取はずし、打込時には鋼
板セル１内の中間位置に治具７を吊下げて維持するのが
望ましい。Note that the lower end of the steel plate cell 1 is on the seabed soil, and the upper end is on the hanging tool 1.
1, buckling and oval vibration of the steel plate cell 1 occur frequently at intermediate positions of the steel plate cell 1 due to driving. It is desirable to remove the jig 7 before driving, and to maintain the jig 7 suspended at an intermediate position within the steel plate cell 1 during driving.

間が少くなるので低コストの工事が可能となる。As described above, the present invention fixes a plurality of steel plates to the outer periphery of a pre-assembled jig via connecting plates, and welds the steel plates to each other to form a cylindrical steel plate cell. After transporting the cell as it is,
Since the above-mentioned connecting plate is removed and the jig separated from the above-mentioned steel plate cell is suspended within the above-mentioned steel plate cell and the above-mentioned steel plate cell is driven, the dimensions and shape of the steel plate cell can be maintained during manufacturing. In order to prevent welding distortion, maintain shape during transportation, and prevent buckling and oval vibration when driving steel sheet cells, we have traditionally used jigs, shape-retaining frames, and reinforcements each time when manufacturing, transporting, and driving steel sheet cells. There is no need to attach or remove the frame, which reduces the number of steps and time required, allowing for low-cost construction.
