Description

Dynamic compaction system with compaction plate {dynamic compaction system with compaction plate}

The present invention relates to a compaction apparatus using a compact plate, and in particular, to maximize the efficiency of the compact plate (plate) and energy designed to ensure that the impact energy by the hammer (hammer) to the ground accurately It is configured to enable ground improvement even at a deep depth of 15m or more as energy.

In general, the dynamic compaction method uses a crane to lift the weight (10-25 tons) of the hammer (Hammer) to a high position (10 to 25 m), and then free-falls to force the ground by the impact and vibration generated at this time. It is a pledge method.

Since this method can apply a large amount of energy, it is possible to improve the ground to a large depth (about 12 m). However, this method is eccentric due to the imbalance of the center and resistance of the wire as the hammer falls, so that it is not in close contact with the ground at the time of striking, but is slightly inclined, and the pit formed by the preceding striking at the time of continuous strike ), The hammer does not come in close contact with the bottom of the crater.

As a result, the loss of the blow energy is very large and the efficiency of the energy is considerably reduced. Therefore, in order to obtain the required improvement effect, very large energy must be generated. To this end, very large and large cranes are required, resulting in poor construction and economical efficiency, and also in the supply and demand of equipment.

On the other hand, the hydraulic hammer compacting method is a method of compacting the ground by using a plate from the hydraulic pressure to repeatedly ground the hammer (7 ~ 13 tons) at a relatively short distance (about 1 ~ 1.5m) to the ground It is a method of improving the ground by the impact by hitting the compacted plate (Plate) in close contact. As a result, rapid and accurate repeated blows can be achieved compared to the compaction method. However, if the crater is deepened due to the blow, the leader and the hammer are easily separated and separated, and the blow is continuously performed as required. It is not possible to proceed, the assembly and disassembly of a large amount of equipment, the time and cost of transportation is enormous, and the cost of oil doubled in cranes and power packs is also a major impediment to the construction cost reduction.

In addition, in the construction after assembly, its own weight is large and its central axis is high, so its mobility is low. Especially, there is a risk of equipment conduction during construction on the soft ground, which is a factor of safety accident. It was a chronic problem with the equipment. In addition, the hydraulic hammer compacting method has a big disadvantage in that the improvement target is limited to within 5 m because the impact energy is very small due to the limitation of the hydraulic pressure.

Therefore, the development of a new concept method and equipment that can solve the problems of construction, economical and equipment supply and demand simultaneously by overcoming the limitations of the above two methods is urgently required.

The present invention has been made to solve the various limitations of the above method, the present invention is in close contact with the compacted plate (Plate) to improve the impact energy is transferred to the ground to the compact plate (Plate) By minimizing the energy loss, the construction speed is greatly improved by maximizing the efficiency to secure the same or more improvement effect as the energy which is much smaller than the dynamic compaction method, and it is larger than the limit of energy that can be generated as a hydraulic hammer. By using energy, the depth of improvement and improvement effect can be greatly increased than the hydraulic hammer compacting method, and the area of application can be expanded even more. Existing equipment has to use a large capacity, but this method has enough improvement effect even with a small amount of equipment. Existing equipment needed a lot of equipment, but this equipment is simple Simple and excellent in weight and mobility, and because it does not use a separate power pack like the hydraulic hammer compacting method, it can reduce the oil cost that is doubled, and because it uses only a small amount of equipment, the equipment supply is smooth and the improvement area is very large. It can be effectively coped with in the region.

In particular, the main improvement aimed at the present invention is a much smaller energy than the conventional dynamic compaction method, which can secure the same or more improvement effect and can be improved by only about 5m. In order to improve the improvement effect to), the present invention provides an improvement for the above-mentioned six items and the use of the small-capacity equipment and the improvement effect to develop for a large depth.

The problem solving means of the present invention is a compact plate and a small force that can be configured integrally with the hammer (Hammer) so that the impact energy can be accurately transmitted to the ground (Wire) to lift the hammer (Hammer) with a small force It is possible to use a small amount of equipment by reducing the large energy used in the conventional compaction method, and thus to escape from limited ground improvement depth (5m) like the hydraulic hammer compaction method and to increase the target improvement depth by more than 15m. As a result, the improvement effect is enlarged and developed into a large depth type.

The effect of the compaction apparatus using the compaction plate according to the present invention, firstly, because the impact energy is accurately transmitted to the ground can be improved to a deep depth (15m or more) as a small energy, significantly reducing the weight and drop of the hammer (hammer) Can be reduced.

Second, since there is no anxiety about the detachment of the hammer during construction, it is possible to generate a large amount of energy by hitting continuously until the required depth of improvement at any time.

Third, because of the special device, the improved compact plate can be used to reduce the time and expense of assembly and disassembly, transportation of equipment, and to reduce the risk of falling on the soft ground. This is greatly improved.

Fourth, the device is simple and easy to improve, and the specially designed rotating shaft allows the hammer to be lifted freely with only a small force, thus eliminating the need for large-capacity equipment and requiring only small-capacity equipment. As it is drastically faster, construction costs are greatly reduced, and equipment supply is easy, the applicability on large sites is excellent.

Fifth, since the hydraulic pressure is not used to lift the hammer, a separate power pack is not required, thereby significantly reducing fuel waste.

Sixth, the vibration and noise can be significantly reduced than the existing method, and the scattering is hardly generated, which is advantageous to the surrounding environment.

According to these various improvements, the present invention can use a small amount of equipment and can improve the ground to a large depth (15 m or more) with only a small force, so that the construction speed and the improvement effect are much better than those of the existing method. The effect on the surrounding environment is remarkably improved, and the supply and demand of equipment is smoothly applied, which greatly improves applicability in large areas.
