Description

本発明は、構造物の基礎として用いられるスクリュー杭の沈下又は施工ミスに伴う高さ不足を補正する方法に関するものである。 The present invention relates to a method for correcting a height shortage due to subsidence of a screw pile used as a foundation of a structure or a construction error.

近年、いわゆるメガソーラー事業者等を中心に、遊休地等にて複数の太陽電池パネルを設置して発電を行う事業が盛んに行われている。このような形態での太陽電池パネルの設置では、地面に基礎を設けてその上方に太陽電池パネルを設置することになる。この場合、工期の短縮や設置コストの削減を図るべく、コンクリート製の基礎ではなくスクリュー杭を基礎として用いる工法が盛んに行われている（一例として特許文献１を参照）。 In recent years, so-called mega solar operators and the like have been actively engaged in the business of installing a plurality of solar cell panels to generate electricity in idle land and the like. In the installation of the solar cell panel in such a form, the foundation is provided on the ground and the solar cell panel is installed above the foundation. In this case, in order to shorten the construction period and reduce the installation cost, a construction method using a screw pile as a foundation instead of a concrete foundation is widely used (see Patent Document 1 as an example).

スクリュー杭は、地上への露出部となる杭の上方部分から、地面に打ち込まれる（すなわち貫入される）先端部分に向けて螺旋状の羽根が設けられた杭であり、尖った先端部を地面に刺してネジのように回転圧入させながら地中へと打ち込まれる。この羽根の存在が杭の引き抜きや沈下への抵抗力となるので、地面に打ち込まれたスクリュー杭は通常の杭に比べて引き抜きや沈下に強く、これを基礎として太陽電池パネルのような重量物を設置することが可能である。 A screw pile is a pile provided with spiral blades from the upper part of the pile that is exposed to the ground toward the tip part that is driven (that is, penetrated) into the ground, and the sharp tip part is the ground. It is driven into the ground while being pierced into the ground and being rotationally press-fitted like a screw. Since the presence of these blades acts as a resistance to pulling out and sinking of piles, screw piles driven into the ground are more resistant to pulling out and sinking than ordinary piles, and based on this, heavy objects such as solar cell panels It is possible to install.

また、太陽電池パネルの設置の場合のみならず、例えば、コンクリート基礎のような構造物の設置が制限される農業用地にビニールハウスを設置する場合でもスクリュー杭は有用である。他にも、設置スペースが少なくて済むということや、工期を短縮したりコストを低く抑えたりするといったメリットを得られることから、スクリュー杭を基礎として活用する場面は少なくない。 Further, the screw pile is useful not only in the case of installing a solar cell panel but also in the case of installing a greenhouse on an agricultural land where the installation of a structure such as a concrete foundation is restricted. In addition, there are many situations where screw piles are used as a foundation because they require less installation space and have the advantages of shortening the construction period and keeping costs low.

特開２０１５－１２７５０１号公報Japanese Unexamined Patent Publication No. 2015-127501

しかしながら、いわゆるメガソーラーの設置が盛んになってから数年が経過した現在では、経年による太陽電池パネルの沈下が問題になる例も散見されるようになった。これは、太陽電池パネルという重量物を支えるスクリュー杭が、時間の経過とともに地面の中へと沈下していくことによるものである。こうした沈下は、一組の太陽電池パネルを支える４本のスクリュー杭の全てで生じることもあれば、４本のスクリュー杭のうちの一部だけで生じることもある。また、複数本のスクリュー杭が沈下している場合にはそれぞれのスクリュー杭で沈下の程度が異なる場合もある。こうした沈下の結果、設置された太陽電池パネルの傾きが意図しないものになり、歪みによるマイクロクラックが太陽電池パネルに生じて発電量の低下や火災を招く原因にもなり得る。また、こうした沈下の問題は、太陽電池パネル設置のための基礎の場合に限らず、あらゆる構造物の基礎としてスクリュー杭が用いられる場合に生じ得ることである。さらに、沈下によらず、施工時に杭の高さを間違えたことにより、これらの問題を生じる場合もある。このような場合に、設置された構造物を取り除いて、基礎であるスクリュー杭の打ち込み施工をやり直すのは多大なコストを必要とするし、現実的でない。 However, now that several years have passed since the installation of so-called mega solar became popular, there are some cases where the subsidence of solar cell panels due to aging has become a problem. This is because the screw pile that supports a heavy object called a solar cell panel sinks into the ground over time. Such subsidence may occur on all four screw stakes that support a set of solar panels, or on only some of the four screw stakes. Further, when a plurality of screw piles are subsided, the degree of subsidence may differ for each screw pile. As a result of such subsidence, the tilt of the installed solar cell panel becomes unintended, and microcracks due to distortion may occur in the solar cell panel, which may cause a decrease in power generation or a fire. Also, such subsidence problems can occur when screw piles are used as the foundation of any structure, not just the foundation for the installation of solar cell panels. Furthermore, regardless of subsidence, the wrong height of the pile during construction may cause these problems. In such a case, it is not realistic to remove the installed structure and redo the driving work of the screw pile which is the foundation, because it requires a large cost.

本発明は以上の状況に鑑みてなされたものであり、基礎であるスクリュー杭の高さ不足を簡便に補正できる施工方法を提供することを目的とする。なお、上記のように、スクリュー杭の高さ不足は、沈下を原因とするものの他に、施工不良を原因とするものも考えられるが、本明細書では、説明の都合上、高さ不足の要因として沈下を例に挙げて説明する。しかしながら、本発明は、沈下による高さ不足の補正に制限されるものではない。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a construction method capable of easily correcting a lack of height of a screw pile which is a foundation. As described above, the insufficient height of the screw pile may be caused not only by subsidence but also by poor construction. However, in this specification, the height is insufficient for convenience of explanation. Subsidence will be explained as an example of the cause. However, the present invention is not limited to the correction of height shortage due to subsidence.

本発明者は、上記の課題を解決するために鋭意検討を重ねた結果、スクリュー杭の高さ不足量を測定してその高さ不足量に対応する長さの棒部材を用意し、その棒部材の両端に、締結具により一対のフランジを取り付けることで補正部材を調製し、この補正部材を構造物とスクリュー杭との間に挿入した後に、構造物及びスクリュー杭と上記一対のフランジとをそれぞれ結合させることで、構造物とスクリュー杭との間に上記補正部材を固定してスクリュー杭の高さを補正すればよいことを見出し、本発明を完成するに至った。具体的には、本発明は以下のようなものを提供する。 As a result of diligent studies to solve the above problems, the present inventor measures the amount of height deficiency of the screw pile, prepares a rod member having a length corresponding to the amount of height deficiency, and prepares the rod member. A correction member is prepared by attaching a pair of flanges to both ends of the member with fasteners, and after the correction member is inserted between the structure and the screw pile, the structure and the screw pile and the pair of flanges are attached. By connecting each of them, it was found that the correction member should be fixed between the structure and the screw pile to correct the height of the screw pile, and the present invention has been completed. Specifically, the present invention provides the following.

以下、本発明のスクリュー杭の高さ不足を補正する方法の一実施態様について図面を参照しながら説明する。なお、本発明は、以下の実施態様に何ら限定されるものでなく、本発明の範囲において適宜変更を加えて実施することができる。 Hereinafter, an embodiment of the method for compensating for the insufficient height of the screw pile of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and can be carried out with appropriate modifications within the scope of the present invention.

まず、本発明のスクリュー杭の高さ不足を補正する方法の実施態様を説明するのに先立ち、本発明の適用されるスクリュー杭について図面を参照しながら説明する。図１は、本発明のスクリュー杭の高さ不足を補正する方法の適用されるスクリュー杭の一例を示す平面図及び側面図である。図２は、スクリュー杭を基礎として地面に設置された太陽電池パネル用の架台を示す側面図である。 First, prior to explaining the embodiment of the method for correcting the height shortage of the screw pile of the present invention, the screw pile to which the present invention is applied will be described with reference to the drawings. FIG. 1 is a plan view and a side view showing an example of a screw pile to which the method of correcting the height shortage of the screw pile of the present invention is applied. FIG. 2 is a side view showing a frame for a solar cell panel installed on the ground based on a screw pile.

スクリュー杭９は、構造物の基礎として用いられるものであり、地面に貫入される先端部９３を備え、この先端部９３の反対側となる末端部である頂部にフランジ９４を備える。フランジ９４には、締結具により構造物を結合させるための結合穴９６が設けられる。図２に示すように、スクリュー杭９を基礎として例えば太陽電池パネル８の架台７を地面に設置する場合、この結合穴９６を介してフランジ９４と架台７の締結部７２とを締結具７３により締結することで、架台７をスクリュー杭９の上部に固定する。 The screw pile 9 is used as a foundation of a structure and includes a tip portion 93 penetrating into the ground, and a flange 94 is provided at a top portion which is an end portion opposite to the tip portion 93. The flange 94 is provided with a coupling hole 96 for coupling the structure by a fastener. As shown in FIG. 2, when the gantry 7 of the solar cell panel 8 is installed on the ground based on the screw pile 9, for example, the flange 94 and the fastening portion 72 of the gantry 7 are fastened by the fastener 73 through the coupling hole 96. By fastening, the gantry 7 is fixed to the upper part of the screw pile 9.

スクリュー杭９には、先端部９３から末端となるフランジ９４へ向けて、螺旋状の羽根９５を備えたスパイラル部９２と、羽根９５を持たない直胴部９１とが形成されている。スクリュー杭９を地面へ貫入させて基礎を形成させるに際しては、先端部９３を地面に刺し、ネジのようにスクリュー杭９を回転圧入させる。通常、スパイラル部９２が地中に没した段階、又は地面の形状に合わせ直胴部９１の一部も地中に没した段階で貫入完了となり、直胴部９１が地上に露出して基礎となる。地中に貫入したスクリュー杭９は、螺旋状の羽根９５の存在により地中での上下への移動が規制されており、荷重による沈下が抑制される。 The screw pile 9 is formed with a spiral portion 92 having a spiral blade 95 and a straight body portion 91 having no blade 95 from the tip portion 93 toward the flange 94 at the end. When the screw pile 9 is penetrated into the ground to form a foundation, the tip portion 93 is pierced into the ground and the screw pile 9 is rotationally press-fitted like a screw. Normally, the penetration is completed when the spiral portion 92 is submerged in the ground, or when a part of the straight body portion 91 is also submerged in the ground according to the shape of the ground, and the straight body portion 91 is exposed to the ground and becomes the foundation. Become. The screw pile 9 that has penetrated into the ground is restricted from moving up and down in the ground due to the presence of the spiral blade 95, and sinking due to a load is suppressed.

しかしながら、スクリュー杭９の適用される地盤の状態によっては、時間の経過とともに、構造物の荷重によりスクリュー杭９の沈下を生じてスクリュー杭９の高さ不足を生じることもあり得る。本発明のスクリュー杭の高さ不足を補正する方法は、そうした沈下や施工不良等による高さ不足を補正し、高さ不足によりずれた構造物の位置を本来の位置に戻すために適用される。以下、太陽電池パネル８の架台７における高さ不足の補正を例として本発明を具体的に説明するが、本発明の適用対象となる構造物はこれに限定されるものではない。 However, depending on the condition of the ground to which the screw pile 9 is applied, the load of the structure may cause the screw pile 9 to sink due to the passage of time, resulting in an insufficient height of the screw pile 9. The method of correcting the height shortage of the screw pile of the present invention is applied to correct the height shortage due to such subsidence, construction failure, etc., and to return the position of the structure displaced due to the height shortage to the original position. .. Hereinafter, the present invention will be specifically described by taking the correction of the height shortage in the gantry 7 of the solar cell panel 8 as an example, but the structure to which the present invention is applied is not limited to this.

本発明の方法で用いられる補正部材１について、図面を参照しながら説明する。図３は、補正部材１を構成する一対のフランジ筒１１、１２を表す平面図及び側面図である。図４は、補正部材１の構成を表す側面図である。図５は、補正部材１を表す側面断面図である。 The correction member 1 used in the method of the present invention will be described with reference to the drawings. FIG. 3 is a plan view and a side view showing a pair of flange cylinders 11 and 12 constituting the correction member 1. FIG. 4 is a side view showing the configuration of the correction member 1. FIG. 5 is a side sectional view showing the correction member 1.

補正部材１は、棒部材１３、及び一対のフランジ筒１１、１２から構成される。棒部材１３は、中空の管状部材（すなわちパイプ部材）であり、胴部１３１と中空部１３２とを備え、その長さは、スクリュー杭９の高さ不足量に対応する。棒部材１３は、予め測定されたスクリュー杭９の沈下量をもとに、その高さ不足量に対応する長さとなるようにパイプ部材から切り出されたものである。「高さ不足量に対応する長さ」とは、補正部材１全体の長さが上記高さ不足量となるように決定された長さであり、上記高さ不足量から、フランジ筒１１、１２に形成されたフランジ１１１、１１２の厚みを差し引いた長さに対応する。 The correction member 1 is composed of a rod member 13 and a pair of flange cylinders 11 and 12. The rod member 13 is a hollow tubular member (that is, a pipe member), and includes a body portion 131 and a hollow portion 132, the length of which corresponds to the height shortage of the screw pile 9. The rod member 13 is cut out from the pipe member so as to have a length corresponding to the height shortage amount based on the subsidence amount of the screw pile 9 measured in advance. The "length corresponding to the height shortage amount" is a length determined so that the total length of the correction member 1 becomes the height shortage amount, and from the height shortage amount, the flange cylinder 11, It corresponds to the length obtained by subtracting the thickness of the flanges 111 and 112 formed in 12.

フランジ筒１１は、フランジ１１１と、棒部材１３が挿入されこれを収容するための挿入部１１３とを備える。挿入部１１３は、一端がフランジ１１１の中央に接合され、他端が開放された管部材であり、その内径が棒部材１３の外径に略一致する。フランジ１１１は、挿入部１１３よりも外周側となる面に、スクリュー杭９のフランジ９４に設けられた結合穴９６と結合するための結合穴１１２を備える。この結合穴１１２が存在することにより、スクリュー杭９の結合穴９６とフランジ１１１の結合穴１１２とを貫通する締結具が、補正部材１をスクリュー杭９の頂部に固定できることになる。 The flange cylinder 11 includes a flange 111 and an insertion portion 113 for inserting and accommodating the rod member 13. The insertion portion 113 is a pipe member having one end joined to the center of the flange 111 and the other end open, and the inner diameter thereof substantially coincides with the outer diameter of the rod member 13. The flange 111 is provided with a coupling hole 112 for coupling with the coupling hole 96 provided in the flange 94 of the screw pile 9 on a surface on the outer peripheral side of the insertion portion 113. The presence of the coupling hole 112 allows the fastener that penetrates the coupling hole 96 of the screw pile 9 and the coupling hole 112 of the flange 111 to fix the correction member 1 to the top of the screw pile 9.

フランジ筒１２は、フランジ１２１と、棒部材１３が挿入されこれを収容するための挿入部１２３と、挿入部１２３の内側となる面に穴１２８とを備える。挿入部１２３は、一端がフランジ１２１の中央に接合され、他端が開放された管部材であり、その内径が棒部材１３の外径に略一致する。フランジ１２１は、挿入部１２３よりも外周側となる面に、構造物である架台７の締結部７２と結合するための結合穴１２２を備える。この結合穴１２２が存在することにより、架台７の脚部７１の末端に設けられた締結部７２とフランジ１２１の結合穴１２２とを貫通する締結具が、補正部材１を架台７の下部に固定できることになる。穴１２８は、フランジ１２１の略中央であって挿入部１２３の内側となる面に設けられる。後述するように、穴１２８を通して、補正部材１の内部にモルタルを充填できるようになる。 The flange cylinder 12 includes a flange 121, an insertion portion 123 into which the rod member 13 is inserted and accommodated therein, and a hole 128 on the inner surface of the insertion portion 123. The insertion portion 123 is a pipe member having one end joined to the center of the flange 121 and the other end open, and the inner diameter thereof substantially coincides with the outer diameter of the rod member 13. The flange 121 is provided with a connecting hole 122 for connecting to the fastening portion 72 of the gantry 7, which is a structure, on a surface on the outer peripheral side of the insertion portion 123. Due to the presence of the coupling hole 122, the fastener that penetrates the fastening portion 72 provided at the end of the leg portion 71 of the gantry 7 and the coupling hole 122 of the flange 121 fixes the correction member 1 to the lower portion of the gantry 7. You will be able to do it. The hole 128 is provided on a surface substantially at the center of the flange 121 and inside the insertion portion 123. As will be described later, the inside of the correction member 1 can be filled with mortar through the hole 128.

棒部材１３は、胴部１３１の下端にフランジ筒１１が挿入され、胴部１３１の上端にフランジ筒１２が挿入される。挿入されたフランジ筒１１、１２は、挿入部１１３、１２３と胴部１３１とを貫通する締結具１４により棒部材１３に挿入された状態で締結され固定される。締結具１４は、具体的にはビスであり、上記の締結がなされた後で棒部材１３の中空部１３２に突き出る長さのものが選択される。 In the rod member 13, the flange cylinder 11 is inserted into the lower end of the body 131, and the flange cylinder 12 is inserted into the upper end of the body 131. The inserted flange cylinders 11 and 12 are fastened and fixed in a state of being inserted into the rod member 13 by a fastener 14 penetrating the insertion portions 113 and 123 and the body portion 131. The fastener 14 is specifically a screw, and one having a length that protrudes into the hollow portion 132 of the rod member 13 after the above-mentioned fastening is made is selected.

棒部材１３と一対のフランジ筒１１、１２とが互いに結合された後、フランジ筒１２に設けられた穴１２８から、モルタル１３３が注入される。モルタル１３３は、棒部材１３の中空部１３２の全部を満たし、さらに穴１２８を埋めるまで注入される。モルタル１３３が固化することにより、棒部材１３の中空部１３２に突出した各締結具１４は、中空部１３２に充填されたモルタル１３３により完全に固定され、経時による脱落や緩みが防止される。これにより、補正部材１が完成される。なお、必要に応じて、棒部材１３と、フランジ筒１１、１２との継目には、パテ等を充填してもよい。 After the rod member 13 and the pair of flange cylinders 11 and 12 are coupled to each other, the mortar 133 is injected from the hole 128 provided in the flange cylinder 12. The mortar 133 is injected until it fills the entire hollow portion 132 of the rod member 13 and further fills the hole 128. As the mortar 133 solidifies, each fastener 14 protruding from the hollow portion 132 of the rod member 13 is completely fixed by the mortar 133 filled in the hollow portion 132, and is prevented from falling off or loosening over time. As a result, the correction member 1 is completed. If necessary, the joint between the rod member 13 and the flange cylinders 11 and 12 may be filled with putty or the like.

次に、補正部材１を用いて、スクリュー杭７の高さ不足を補正する方法について図面を参照しながら説明する。図６（ａ）～（ｄ）は、スクリュー杭７の高さ不足を補正する方法の手順を示す側面図である。 Next, a method of correcting the height shortage of the screw pile 7 by using the correction member 1 will be described with reference to the drawings. 6 (a) to 6 (d) are side views showing a procedure of a method of correcting the height shortage of the screw pile 7.

まず、スクリュー杭９の高さ不足量を測量し、その高さ不足量に応じた長さを備えた補正部材１を調製する。既に説明したように、補正部材１は、両端に一対のフランジ１１、１２を備え、スクリュー杭９のフランジ９４と架台７の締結部７２との間に挿入及び固定されて、スクリュー杭７の高さ不足量を補償する。 First, the height shortage of the screw pile 9 is measured, and the correction member 1 having a length corresponding to the height shortage is prepared. As described above, the correction member 1 is provided with a pair of flanges 11 and 12 at both ends, and is inserted and fixed between the flange 94 of the screw pile 9 and the fastening portion 72 of the gantry 7 to increase the height of the screw pile 7. Compensate for the shortage.

まず、図６（ａ）に示すスクリュー杭９の周囲の地面６を取り除き、地面に埋まったスクリュー杭９の直胴部９１の一部を露出させる。次いで、露出した直胴部９１の地中部分に沈下防止パーツ３を取り付ける（図６（ｂ））。沈下防止パーツ３は、スクリュー杭９のこれ以上の沈下を抑制するために設けられるものであり、その構成の詳細は後述する。スクリュー杭９の直胴部９１に沈下防止パーツ３を取り付けた後、取り除いた地面を埋め戻す。これにより、沈下防止パーツ３は、地中に埋められることになる。 First, the ground 6 around the screw pile 9 shown in FIG. 6A is removed to expose a part of the straight body portion 91 of the screw pile 9 buried in the ground. Next, the subsidence prevention part 3 is attached to the underground portion of the exposed straight body portion 91 (FIG. 6 (b)). The subsidence prevention part 3 is provided to suppress further subsidence of the screw pile 9, and the details of its configuration will be described later. After attaching the subsidence prevention part 3 to the straight body portion 91 of the screw pile 9, the removed ground is backfilled. As a result, the subsidence prevention part 3 is buried in the ground.

次いで、スクリュー杭９と架台７とを結合する締結具７３を取り外し、架台７をジャッキアップして、スクリュー杭９のフランジ９４と架台７の締結部７２との間を離間させる（図６（ｃ））。その後、離間したフランジ９４と締結部７２との間に補正部材１を挿入し、補正部材１の下方のフランジ１１とスクリュー杭９のフランジ９４とを締結具９６により結合して固定させるとともに、補正部材１の上方のフランジ１２と架台７の締結部７２とを締結具７３により結合して固定させる（図６（ｄ））。 Next, the fastener 73 that connects the screw pile 9 and the gantry 7 is removed, the gantry 7 is jacked up, and the flange 94 of the screw stake 9 and the fastening portion 72 of the gantry 7 are separated from each other (FIG. 6 (c). )). After that, the correction member 1 is inserted between the separated flange 94 and the fastening portion 72, and the flange 11 below the correction member 1 and the flange 94 of the screw pile 9 are coupled and fixed by the fastener 96, and the correction is performed. The upper flange 12 of the member 1 and the fastening portion 72 of the gantry 7 are connected and fixed by the fastener 73 (FIG. 6 (d)).

これらの各工程を経ることにより、図７に示すように、架台７の基礎となるスクリュー杭９の高さが補正される。図７は、本発明により、基礎であるスクリュー杭９の高さが補正された太陽電池パネル８用の架台７を示す側面図である。 By going through each of these steps, as shown in FIG. 7, the height of the screw pile 9 that is the basis of the gantry 7 is corrected. FIG. 7 is a side view showing a gantry 7 for the solar cell panel 8 in which the height of the screw pile 9 which is the foundation is corrected by the present invention.

次に、沈下防止パーツ３の構成について図面を参照しながら説明する。図８は、本実施態様で用いられる沈下防止パーツ３を示す斜視図である。 Next, the configuration of the subsidence prevention part 3 will be described with reference to the drawings. FIG. 8 is a perspective view showing the subsidence prevention part 3 used in the present embodiment.

本実施態様で用いられる沈下防止パーツ３は、半沈下防止板３２１と半挿入筒３３１とを備えたパーツＡと、半沈下防止板３２２と半挿入筒３３２とを備えたパーツＢとの二つのパーツからなる。 The subsidence prevention parts 3 used in the present embodiment are two parts, a part A having a semi-sink prevention plate 321 and a semi-insertion cylinder 331, and a part B having a semi-sink prevention plate 322 and a semi-insertion cylinder 332. It consists of parts.

図８に示すように、二つのパーツを一組とした沈下防止パーツ３は、半挿入筒３３１と半挿入筒３３２とが対向するようにパーツＡとパーツＢとを組み合わされ、スクリュー杭９が挿入される挿入筒３３と、挿入筒３３から延出し、挿入筒３３の長さ方向を垂直に立てたときこれから水平に離れる方向へ拡がる沈下防止板３２が形成される。つまり、二つ一組となった半挿入筒３３１、３３２が挿入筒３３を形成し、二つ一組となった半沈下防止板３２１、３２２が沈下防止板３２を形成する。 As shown in FIG. 8, in the sinking prevention part 3 which is a set of two parts, the part A and the part B are combined so that the half-insertion cylinder 331 and the half-insertion cylinder 332 face each other, and the screw pile 9 is formed. An insertion cylinder 33 to be inserted and a sinking prevention plate 32 extending from the insertion cylinder 33 and extending in a direction horizontally separated from the insertion cylinder 33 when the length direction of the insertion cylinder 33 is erected vertically are formed. That is, a pair of semi-insertion cylinders 331 and 332 form an insertion cylinder 33, and a pair of semi-settlement prevention plates 321 and 322 form a subsidence prevention plate 32.

半挿入筒３３１と半挿入筒３３２には、スクリュー杭９の直胴部９１にビス留めするための穴３４が設けられ、この穴３４を通してパーツＡ及びパーツＢがスクリュー杭９にビス留めされることにより、スクリュー杭９には、スクリュー杭９から水平に離れる方向に拡がる沈下防止板３２が形成されることになる。 The half-insertion cylinder 331 and the half-insertion cylinder 332 are provided with a hole 34 for screwing to the straight body portion 91 of the screw pile 9, and the parts A and B are screwed to the screw pile 9 through the hole 34. As a result, the screw pile 9 is formed with a subsidence prevention plate 32 that expands in a direction horizontally separated from the screw pile 9.

以上、本発明のスクリュー杭の高さ不足を補正する方法の一実施態様について説明したが、本発明は上記の実施態様に限定されるものではない。 Although one embodiment of the method for correcting the insufficient height of the screw pile of the present invention has been described above, the present invention is not limited to the above embodiment.
