The present invention relates to a sand laying apparatus and a method thereof, and more particularly, it is used in the reclamation construction of the coast or harbor, and particularly easy to enter the various drainage equipment for use in the early drying operation of the dredged soil dumped in the landfill area The present invention relates to a sand laying apparatus and a method for easily forming a sand laying layer.

In general, landfill sites such as coasts and harbors are constructed to be converted into various industrial and agricultural sites through a process of dumping dredged soil to a landfill site and a process of drying dumped dredged soil.

The drying of the dredged soil is a method of allowing the dredged soil dumped in the landfill to be left in the general air environment as it is naturally dried, but this method takes about 5 years or more for the drying of moisture, so in recent years Consolidation settlement methods that make up for the shortcomings are widely used.

In the consolidation settlement method, a plurality of paper drain boards are embedded in the dredged soil and the ground layer to dry while forcibly draining the water in the dredged soil layer by the drain board.

Since the consolidation settlement is performed by various heavy equipments, sand is laid to form a sand laying layer having a mat function by allowing sand to enter heavy equipment on a soft dredged soil layer before drying, and then drying on the sand laying layer. The work is in progress.

The sand laying operation forms a sand laying layer by spraying sand for laying in the dredged soil area using pressure air by a large blower at a point outside the dredged soil area.

However, the conventional sand laying work for dredged soil drying is a method of dumping sand for laying by the air pressure toward the dredged soil dumping area from the point out of the dredged soil dumped area, so that the entire dredged dumped land is uniform. It is difficult to form sand laying layer.

In particular, since the installation is limited to the injection length limited by the blower outside the large-sized dredged soil dumping zone, a phenomenon in which the sand laying layer is concentrated only in the border region except the center portion of the landfill occurs.

In addition, if the sand laying layer is formed non-uniformly in the dredged soil dumping area as described above, the ground subsidence occurs when entering the heavy equipment for drainage, which leads to restrictions on the mobility of the equipment, and thus, excessive time is required for the drying operation. Smooth drainage becomes difficult.

The present invention has been made to solve the conventional problems as described above, the object of the present invention can easily form a sand laying layer for the drying operation of the dredged soil zone dumped in the landfill area, in particular dredged soil dumping zone It is possible to install sand for laying in the state of entering the present invention to provide a sand laying apparatus and method which can obtain improved work efficiency and laying quality.

The sand for laying (S) sprayed by the nozzle (N) is supplied along the transfer section through the belt conveyor (B1), and is stored in the storage space by the stepped conveyor (B2) installed in the laying cart (8). Sprayed in the state contained in (12).

When the sand laying layer S1 is formed along the transport section set to cross the dredged soil dumping area A by the laying process, the support 2, the rail 4, and a belt conveyor ( After dismantling B1) and the trolley for laying 8, as shown in FIG. 9, another transfer section for laying sand S for laying is formed at an adjacent point where the sand laying layer S1 is formed. .

In addition, the sand laying layer S1 is formed by laying the sand S for laying in the dredged soil dumping area A as described above along another transfer section for laying the sand for laying sand S. And, while repeating this process, as shown in Figure 10 to form a sand laying layer (S1) uniformly throughout the dredged soil dumping zone (A).

In the above-described embodiment, an installation operation is performed while forming a transport section for installing sand S for installing the sand corresponding to the entire length in the direction crossing the dredged soil dumping area A and moving along the entire transport section. Although shown in description and drawings, it is not limited to this.

For example, by dividing the entire length of the conveying section across the dredged soil dumping area A into a certain size, forming a conveying section in the divided length range, performing partial laying in the divided section, and then gradually moving forward. You can also do it.

As described above, the present invention, the sand laying layer can be easily installed to facilitate the entry of heavy equipment for drying on the dredged soil layer dumped in the landfill, in particular, the sand for laying in the state of entering the dredged soil dumping zone Direct laying provides a uniform sand deposit throughout the dredged soil dumping area.

Therefore, the time required for sand laying can be greatly reduced, and further improved work efficiency and laying quality can be obtained.
