DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus used for the construction of underground structures such as large-diameter piles, wells, and caissons.

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.

In order to solve the above-mentioned conventional problems, the present invention has developed an apparatus capable of excavating the ground while moving the nozzle along the lower end of the submerged object, that is, along the cutting edge.

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.

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.

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.
