次に施工方法について、図5の第1工程から図13の第9工程に基いて説明する。尚、この施工は図2で示したような基礎4における角や交差点の箇所の複数箇所が同時に行われるものである。   Next, the construction method will be described based on the first step in FIG. 5 to the ninth step in FIG. This construction is performed at the same time at a plurality of corners and intersections in the foundation 4 as shown in FIG.

図5の第1工程に示すように、建造物1の傾斜して低い側の基礎4回りを掘削する。そして図6の第2工程に示すように、基礎4の下方まで掘削を行って掘削を完了する。次に図7の第3工程に示すように、掘削孔20の底面に鋼管からなる杭3を立てると共にこの杭3と基礎4間に昇降駆動手段としての押し上げ手段9Aを介在する。尚、ここで使用される押し上げ手段9Aが動力式油圧ジャッキの場合にはモータやエンジン駆動の動力式油圧ポンプ9Pが接続される。   As shown in the first step of FIG. 5, the building 1 is excavated around the foundation 4 on the lower side with the inclination. And as shown to the 2nd process of FIG. 6, excavation is performed to the downward direction of the foundation 4, and excavation is completed. Next, as shown in the third step of FIG. 7, a pile 3 made of a steel pipe is erected on the bottom surface of the excavation hole 20, and a push-up means 9 </ b> A as an elevating drive means is interposed between the pile 3 and the foundation 4. When the push-up means 9A used here is a power hydraulic jack, a motor or engine driven power hydraulic pump 9P is connected.

図8の第4工程に示すように、押し上げ手段9Aを作動して作動部16を上昇すると、地盤が軟弱なために建造物1が押し上げられずに杭3が下方に押し込まれる。この際、杭3は図3に示すように円筒状継手21を介して、さらなる杭を形成する円管状の短管22が接続されて所定深さに達するようになっている。そして、杭3が支持層2に達した段階で杭3の下方への押し込みは停止する。すなわち、短管22を含む基礎の杭3を地盤の支持層2まで建造物1の重量を利用して杭3を押し込む。   As shown in the fourth step of FIG. 8, when the push-up means 9A is actuated to raise the operating portion 16, the building 1 is not pushed up and the pile 3 is pushed downward because the ground is soft. At this time, as shown in FIG. 3, the pile 3 is connected to a circular short tube 22 forming a further pile via a cylindrical joint 21 so as to reach a predetermined depth. Then, when the pile 3 reaches the support layer 2, the downward pushing of the pile 3 stops. That is, the pile 3 is pushed into the foundation pile 3 including the short pipe 22 by using the weight of the building 1 to the support layer 2 of the ground.

このようにして、図2で示した第1の連結装置5、第2の連結装置6の個所に杭3を配置する。   In this way, the piles 3 are arranged at the locations of the first connecting device 5 and the second connecting device 6 shown in FIG.

次に図9の第5工程に示すように、杭3上にある動力式油圧ポンプ9Pが接続された押し上げ手段9Aをそれぞれ撤去する。そして、基礎4の角などに配置されているそれぞれの杭3の上面に第1の連結装置5を押し上げ手段9と共に設置する。また、基礎4の角などの以外に配置されているそれぞれの杭3の上面に第2の連結装置6を押し上げ手段15と共に設置する。前記第1の連結装置5の設置は、杭3の上面に下部部材7を載置し、その中央に、すなわち四方にあるガイド部11の内側に位置して下部部材7の中央に押し上げ手段9を設置する。さらに、ガイド部11がガイド部受け部12に挿入するようにして上部部材8を取り付ける。この際、押し上げ手段9の作動部16が貫通部17に対向するように上向きに取り付ける。そして、上部部材8に基礎4との当て材23として、基礎4或いは後述するコンクリート26と同様な材質であるコンクリートからなるブロックを介在する。この当て材23は、必要に応じて設けられるものであって、平面は上部部材8とほぼ同じ大きさに形成されており、そして予めガイド部11をガイド部受け部12に挿入すると共に、固定手段13をガイド部11のやや上方に螺合し、該固定手段13に下方開口縁14Aを係止させることで、上部部材8と礎4との間に当て材23の厚みよりやや大きい間隙を形成し、その後上部部材8と基礎4との間に当て材23を挟み込み、次に押し上げ手段9を人力で作動させてその作動部16を、貫通部17を通して当て材23の下面に当接する。   Next, as shown in the fifth step of FIG. 9, the lifting means 9A connected to the power hydraulic pump 9P on the pile 3 is removed. And the 1st connection apparatus 5 is installed with the raising means 9 on the upper surface of each pile 3 arrange | positioned at the corner | angular of the foundation 4, etc. Further, the second connecting device 6 is installed together with the push-up means 15 on the upper surface of each pile 3 other than the corners of the foundation 4. The first connecting device 5 is installed by placing the lower member 7 on the upper surface of the pile 3 and pushing it up at the center thereof, that is, inside the guide portion 11 in the four directions, at the center of the lower member 7. Is installed. Further, the upper member 8 is attached so that the guide portion 11 is inserted into the guide portion receiving portion 12. At this time, the push-up means 9 is mounted upward so that the operating portion 16 faces the penetrating portion 17. And the block which consists of concrete which is the material similar to the foundation 4 or the concrete 26 mentioned later is interposed in the upper member 8 as the contact material 23 with the foundation 4. The abutting member 23 is provided as necessary, and the flat surface is formed to be approximately the same size as the upper member 8, and the guide portion 11 is inserted into the guide portion receiving portion 12 in advance and fixed. By screwing the means 13 slightly above the guide portion 11 and locking the lower opening edge 14A to the fixing means 13, a gap slightly larger than the thickness of the pad 23 is provided between the upper member 8 and the foundation 4. After that, the abutting member 23 is sandwiched between the upper member 8 and the foundation 4, and then the push-up means 9 is operated manually to bring the operating portion 16 into contact with the lower surface of the abutting member 23 through the penetrating portion 17.

同様に、第2の連結装置6を設置する。この取り付けは第1の連結装置5と異なり、押し上げ手段15の作動部15Aは上部板部材19の下面に当て材23Aを介在して当接するようになっており、上部板部材19により直接的に基礎4を押し上げたり、或いは上部板部材19と基礎4との間に当て部材を介在して基礎4を押し上げるようにしている。   Similarly, the 2nd coupling device 6 is installed. This attachment is different from the first connecting device 5, and the actuating portion 15 A of the push-up means 15 is in contact with the lower surface of the upper plate member 19 with a backing material 23 A interposed therebetween. The foundation 4 is pushed up, or a foundation member is interposed between the upper plate member 19 and the foundation 4 to push up the foundation 4.

尚、この第1の連結装置5及び第2の連結装置6の設置作業は一度に総ての個所で行うと建造物1がさらに沈下するおそれがあるので、1箇所ごとか或いは数箇所ごとに建造物1が沈下しないように分けて作業を行う。   It should be noted that if the installation work of the first connecting device 5 and the second connecting device 6 is performed at all locations at once, the building 1 may further sink. The work is divided so that the building 1 does not sink.

さらに総て或いは一部の押し上げ手段9,15を作動して作動部16を上昇すると、支持層2に支持された杭3上にある押し上げ手段9,15は基礎4、ひいては建造物1を重力に抗して水平状態になるまで持ち上げる。これにより、基礎4が水平に戻って建造物1はほぼ矯正される。この際、押し上げ手段9においてはその作動部16が貫通部17を通して当て部材23、ひいては基礎4を押し上げる。また押し上げ手段15においてはその作動部15Aが上部板部材19、ひいては基礎4を押し上げる。   Further, when all or a part of the pushing means 9 and 15 are operated to raise the operating portion 16, the pushing means 9 and 15 on the pile 3 supported by the support layer 2 gravitate the foundation 4 and eventually the building 1. Lift until level. Thereby, the foundation 4 returns to the horizontal level and the building 1 is almost corrected.
