The waterjet method is a conventional construction method for depositing large-diameter piles and other underground structures. This method uses multiple high-pressure hoses together, or a ring-shaped hose is installed at the bottom end, and multiple nozzles are placed on this hose, or even only one nozzle is used, and the nozzle position is fixed. As a result, the ground will be excavated at intervals or in parts. Furthermore, if water jet is to be ejected from multiple nozzles at the same time, a considerably large pump is required.

The apparatus for depositing a submerged object, which is the gist of the present invention, is provided with a guide pipe bent along the lower end of the submerged object, and slides inside the guide pipe and protrudes from a slit provided in the length direction of the guide pipe. It consists of a high-pressure hose for water jets with a nozzle.

The details will be explained below with reference to illustrated embodiments. A guide pipe 2 is installed vertically along the inner wall of the deposit 1 made of a large-diameter steel pipe or the like, and has a tip bent along the lower end of the deposit 1, preferably along the inner circumference of the lower end. A slit 3 opening downward is formed along the entire length of the guide pipe 2. A high pressure hose 4 is slidably inserted into the guide pipe 2.
この高圧ホース4の先端部には1〜4個のノズ
ル5か所要間隔あるいは位置に設けてあり、この
ノズル5はガイドパイプのスリツト3から下向き
に突出させてある。 At the tip of the high-pressure hose 4, one to four nozzles 5 are provided at required intervals or positions, and the nozzles 5 project downward from the slit 3 of the guide pipe.

沈下させる。 During construction, the nozzle 5 is moved along the lower end of the sediment 1 by sliding the high-pressure hose and the nozzle 5 protruding from the hose within the guide pipe 2, and the high-pressure water jet is supplied from the nozzle 5. The ground A below the deposited material 1 is excavated, and the deposited material 1 is caused to sink into the ground A along the excavated groove.
ノズル5を移動させる方法としては高圧ホース
4にエンドレスのワイヤー6を固定し、滑車7,
8を通し、油圧シリンダー9と連結しておく。 To move the nozzle 5, an endless wire 6 is fixed to the high pressure hose 4, and a pulley 7,
8 and connect it to the hydraulic cylinder 9.
油圧シリンダー9の作動によりワイヤー6を交

This invention has the above-mentioned configuration, and since the nozzle for ejecting high-pressure water jet can be moved along the lower end of the submerged object, it is possible to completely eliminate the ground to be submerged using a small number of nozzles. This makes the submersion work easier and more reliable. Moreover, since the high pressure hose with the nozzle protruding from it slides within the guide pipe, the nozzle can be easily moved.
