した（特願昭５４−１５２５７２参照）。In general, support piles have a large vertical bearing capacity, but their horizontal resistance is low. On the other hand, buildings that stand on soft ground or platforms with no basement floor are exposed to wind pressure (/() due to the horizontal resistance force of the supporting piles, which causes most of the horizontal force, and the above-mentioned Conventional buildings, in which most of the horizontal force is received by support piles with weak horizontal resistance, are structurally weak, and there is no perfect countermeasure against uneven settlement. , the applicant has proposed to improve the horizontal bearing capacity and horizontal stratification of the support piles against horizontal external forces such as wind and wind by installing an underground wall between the support piles driven into the ground. In addition, we have created an underground pile foundation that reduces displacement and reduces the annual settlement of the pile by 1JCa (see Japanese Patent Application No. 54-152572).

ｎていなかった。However, in the invention related to the above patent application, he erected a support pile, excavated an area around the support pile, and then integrated an underground wall made of poured concrete with the support pile. A great deal of time and effort was required for the construction. Next, no one had thought of a construction method in which the metal is cast between the support plates, which exhibits extremely high resistance to horizontal loads.

る方法もめる。The method for constructing a pile foundation with an underground wall 2 and a first-floor place according to the present invention is to erect a foundation pile with a joint part in the 1g1 part into the ground with the contacting part facing each other, and to place the foundation pile between the foundation piles. excavate a groove by myself, and then install an underground wall 1 in the excavated groove.
This is done by engaging the left and right edges of the underground place with the above-mentioned joints and guiding it at the joint part, and in the ground, the WJJ foundation pile and the underground wall ft are connected to the pond place. In addition to the method of excavating and building as described above, there is also a method of installing equipment i1 that excavates or weakens the ground in the lower four parts of the underground wall or underground place. quarrel.

fIA1!1l11 is excavated, and an underground wall or underground place t is assembled on the ground in advance in this excavated trench, and the left and right edges thereof are secured to the joint and are guided by the joint, and are erected; Do not use mortar or concrete at joints in the ground.
) to integrate the foundation pile and underground wall or underground place, it is possible to omit the excavation work, cleaning work 2, and concrete work around the foundation pile, which are unavoidable in the American construction method. By using the same method, underground walls and underground places can be built extremely easily and quickly in excavated trenches, thereby significantly shortening the construction period, simplifying the construction work, and saving labor. In addition, dimensional errors due to variations in the pitch between foundation piles and inclination of the foundation piles can be absorbed very easily by the joints provided on the sides of the foundation piles. Additionally, American piles such as steel pipe piles and concrete piles can be used, reducing construction costs.
