【発明の詳細な説明】 〈産業上の利用分野〉 この発明は、建て込むべき鋼矢板やＨ型鋼杭。[Detailed description of the invention] <Industrial application field> This invention is for steel sheet piles and H-shaped steel piles to be erected.

矢板等の下部を拘束する装置に関するものである。In order to restrain steel pipe piles (hereinafter referred to as "1ill sheet piles, etc.") along with the auger casing of the earth auger,
The present invention relates to a noiseless and vibration-free press-fitting apparatus for steel sheet piles, etc., in which the upper part of the steel sheet piles, etc. can be gripped by a hydraulic chuck, and particularly to a device for restraining the lower part of the steel sheet piles, etc.
〈従来の技術〉
鋼矢板の場合を例に挙げ、従来の技術を説明すると、つ
ぎのとおりでおる。<Conventional technology> The conventional technology will be explained as follows, taking the case of steel sheet piles as an example.

の場に残すようになし、以後、同じ操作を繰り返す無騒
音、無振動工法が従来公知でおる。Driving steel sheet piles with a diesel hammer or vibrohammer causes tremendous noise and vibration, making it almost impossible to use in urban areas. After pressing the steel sheet pile into the soil to a specified depth while excavating with the earth auger, the earth auger is rotated in the opposite direction and the steel sheet pile is dug up while backfilling. A noise-free and vibration-free construction method is known in the art, in which the same operation is repeated.

下向きの係止金具を固着しておき、建て込むべき鋼矢板
のそれぞれには上記係止金具と嵌合する係合用の金具を
現場溶接で取付けていた。If only the upper end of the steel sheet pile is held and the lower end is left free, excessive force will be applied to the steel sheet pile during press-fitting, which may cause problems such as twisting and buckling. Conventionally, a downward-facing locking fitting was fixed in advance to the lower end of the auger casing so that even if it was integrally restrained with the auger casing during press-fitting, the restraint could be released when the earth auger was pulled out. In advance, each of the steel sheet piles to be erected was fitted with an engaging fitting that would fit with the above-mentioned locking fitting by welding on site.
〈発明が解決しようとする問題点〉

らないため、この分更に費用が嵩むといった欠点がおっ
た。<Problems to be solved by the invention> As mentioned above, in order to attach fittings for engagement to each steel sheet pile by on-site welding, an extra lane is required to rehang the steel sheet piles, and the fittings Not only does it add up to a considerable amount of money if you include the cost of welding and welding, but also because steel sheet piles are usually leased items, the welded parts must be cut and removed after use and returned. This has the disadvantage of further increasing costs.

。<Means for Solving the Problems> The present invention eliminates the trouble of welding the metal fittings or cutting and removing them by making the lower edge of the steel sheet pile etc. an engagement point in place of the conventional engagement metal fittings. I came up with the idea that it would be possible. Even when the lower end edge of a steel sheet pile or the like is used as an engagement point in this way, it can be reliably restrained integrally with the auger casing during press-fitting, but the restraint must be released when handling the earth auger. Therefore, in this invention, two rods each having a hook part formed at the lower end for receiving the lower edge of the steel sheet pile, etc., are attached to the auger casing, and the above-mentioned hook part is attached to the steel plate by a hydraulic jack for raising and lowering the rods. By making it possible to push down below the lower edge of the sheet pile, etc., and by turning the direction of the pushed down hook part in a direction that does not engage with the steel sheet pile, etc., by means of the rotating means of the rod. It achieved its intended purpose.

る。以上述べたところ迄は従来のものと変わりない。The earth auger advancing device @4 includes a rotating device for the auger screw 7, a turning device that allows the auger casing 8 surrounding the outside of the auger screw 7 to be rotated at any angle, and an auger casing as described below. In order to press in the steel sheet piles 9 attached to the steel sheet piles 8 as needed, the steel sheet piles 8 are usually provided with a pushing device consisting of a hydraulic cylinder. A hydraulic chuck 10 for gripping and releasing the upper end of the suspended steel sheet pile 9 is attached to the upper part of the auger casing 8 by a convenient mounting means for changing its fixing position according to the length of the steel sheet pile 9 used. It is installed. The steel sheet pile 9 held by the hydraulic shack 10 can be set in a direction to properly mesh with the existing steel sheet pile by the turning device. Up to the point described above, there is no difference from the conventional one.

１造を示している。The two water rods 14, 14 have a length extending further below the lower end of the auger casing 8, and have a hook-shaped hook portion 19, 19 formed at the lower end thereof. This hook portion 19.19 is a portion that engages with the lower edge of the steel sheet pile 9 and restrains it. If necessary, to further strengthen the restraint, a stop plate 20 (see FIG. 2) may be welded to the lower end of the auger casing 8, and the rod 14.1
The steel sheet pile 9 may be pressed against the backing plate 20 with the hook portions 19, 19 of 4 engaged with the lower edge of the steel sheet pile 9. Since the rod 14.14 is long, for example, the annular member 1
A guide collar 21 is welded to the auger casing 1, or similar collars are welded to appropriate locations on the auger casing 8 to guide the auger casing. In addition, if the two annular members 11 and 12 are connected by a hinge and have a structure in which the lily faces are tightened with bolts, the two annular members 11 and 12 can be separated depending on the length of the steel sheet pile 9 used. It is easy and convenient when you want to change the mounting position. In the figure, 22 is a hinge for this purpose.
It shows 1 structure.
