Technical Field

The present invention relates to a compaction apparatus using a vibration hammer.

In other words, a vibration tamper (hereinafter referred to as "vibration hammer"), which is a type of vibration hammer, is mounted on a heavy construction equipment (hereinafter referred to as "construction heavy equipment") such as a crane, an excavator, a bulldozer, and compacted at the bottom thereof. Plates are installed to facilitate the entry and movement of the equipment on soft grounds so that the dredged landfills, sandy soils, alluvial lands and waste landfills are efficiently compacted.

Prior art

If a building is built on a soft ground, the ground is destroyed or a consolidation settlement occurs due to the load of the building, and ground improvement is performed to reinforce and stabilize the ground directly or indirectly to prevent it.

For example, when roads and railroads are made on soft ground, the pile up is most frequently performed. The improvement of soft ground, which is the basis of pile up, is mainly by sand draining the clay layer by consolidating and dehydrating clay layers. Increase strength.

In recent years, sand drain is also applied by applying various high-concentration agents to the sand drain to chemically harden the surrounding ground or to harden the sand drain to consolidate the clay layer and strengthen the sand drain.流 工 法) is used.

Such ground improvement works are mainly applied to the pile of soil, and most of them take a method of supporting the foundation ground by type of concrete piles without ground improvement.

In addition, when the foundation ground of an already installed structure is weakened due to various reasons or the damage is expected due to the excavation of adjacent ground, it is necessary to reinforce the ground itself in the state that it is impossible to directly reinforce the concrete pile. The technique is used.

This injection method is to stabilize cement by injecting cement and chemical liquid into the ground at high pressure, but it is effective in the sandy ground but it is difficult to inject clay or silty fine ground of silt. There is no.

Particularly effective methods for clay grounds include electroinfiltration methods for dehydration and electrochemical stability by applying DC voltage to the ground, and sintering methods for excavating smoke passages in the ground and melting and solidifying them around with high heat. This is but not used well.

On the other hand, by directly pressing the surface layer in addition to this method, by using a compacting method to reduce the voids between the particles to strengthen and stabilize the ground.

This compacting method is to compact the ground in order to increase the density of the sandy ground and increase the stability, and the apparatus or machine used in this method is called a compacting machine (tamping machine).

Compaction machines used in this process include roller systems such as load rollers, tandem rollers, compaction rollers and vibration rollers, and vibration compactors, rammers and tampers.

Road rollers are commonly found in road construction sites, etc., and are used for finishing pavement or foundation work. Compaction rollers are used for compacting soil by having a lot of protrusions on the roller part.

In addition, the vibrating roller is a compacting effect by the vibration of the roller portion, the effect is comparable to the 15t-grade roller, even if the relatively light weight of 2 to 4t, the vibratory compactor is a flat plate It is.

On the other hand, vibration compactors, rammers, and tampers, which are used to lay foundations using large grains of coarse stone, are compacted by adding mechanical forces other than steel wheels or the weight of the impact plate to the final part to be compacted. At the same time, the structural parts are made to be strong, and at the same time, the shock absorber is installed to form durability so that vibration is not transmitted to other parts except the working device.

Vibration compactor is a machine for compacting by vibrating a round cylindrical iron wheel or striking plate (vibration plate, compaction plate), which is a compaction device, by vibrating compaction. Compaction capacity is variable by weight and vibration force.

The rammer is equipped to use the explosive energy of the internal combustion engine to compact it by the falling weight generated when the machine itself leaps and falls freely, and it supports manpower and the limits of the internal combustion engine to obtain the power to leap. Due to the weight limit, it is made compact and easy to compact and move in narrow places.

The tamper generates the vibration as the spring attached to the upper part expands while the piston moves up and down linearly by the up and down motion of the connecting rod, and the gas jumps by the expansion and contraction of the lower spring. At the same time, the free-falling impact force is transmitted to the striking plate, and at the same time, the expansion and contraction of the upper spring and the extension of the lower spring are alternately repeated, and the vibration and shock are continuously transmitted to the striking plate at the same time.

Figure 1 is an exemplary view schematically showing the structure of the compaction equipment (hereinafter referred to as 'prior art 1') according to the prior art, compaction equipment 100 and the crane 110 to adjust the compaction position while moving on the ground; , The wire winding part 120, the arm part 130, and the compaction part 140.

The crane 110 is provided to have a good orbit with a light load while moving well, and the power generating unit, the control unit and the operation unit, and a steering device necessary for the movement are provided therein.

The arm portion 130 has a plurality of beams (131, 132, 133) having a predetermined length is connected to one is fixed to one side of the crane 110, the height is lowered on the wire 121 wound on the wire winding part 120 Is adjusted by

The compaction unit 140 includes an impact piston having two pressure surfaces, an accumulator, an inlet tube for supplying pressure fluid to the impact hammer, a return tube for guiding the pressure fluid out of the impact hammer, and guides high pressure and low pressure. Is connected to alternately act on at least one pressure surface of the shock piston, the main valve for reciprocating the shock piston, the inlet tube, driven by the internal pressure, the pressure acting on the control pressure valve is preset The known vibration hammer 141, which is composed of a control pressure valve connected to control the main valve during the return of the shock piston, is connected with the vibrator 142 so that the control valve can be restrained when the value is exceeded. It is connected to and fixed to the hook 122 provided at the end of the wire 121 that extends vertically via the upper end of the arm portion 130 in a state.

In addition, the compaction plate 143 having a predetermined area is coupled to the lower end of the vibration hammer 141 to be replaceable.

The compaction device operates the crane 110 to move the compaction unit 140 to the compaction position of the ground that requires compaction construction, and then operates the operation unit to compact the shock generated by the vibration hammer 141 at the lower portion thereof. The plate 143 is transmitted to the ground and pressurized to ground.

However, the compaction equipment 100 shown in FIG. 1 has the height of the arm portion 130 which is rotatably installed on the crane 110 in the process of compacting the ground, which is higher than several tens of meters. There was a problem that the efficiency of the work is reduced along with the risk of safety accidents when the work is affected.

In addition, if the bottom surface of the compaction plate that performs the compaction work is composed of a simple flat plate, and there is gravel, amber stone, lump or construction waste in the ground, the gap between the rocks and the like is completely filled even if the compaction work is performed After the compaction work is completed in the unsupported state, after the compaction work is completed, the ground is not settled or cracked due to seasonal changes in the process of using it as a road or a runway. ) Was shaken from side to side and left and right, there was a problem that the flow occurs badly.

As such, when the flow of the compaction plate 143 is severely generated, not only the compaction work is properly performed, but also the risk of a safety accident during work increases.

In addition, in order to sequentially move the compaction unit 140 as shown in FIG. 2, the compaction unit 140 must be lifted and moved using the wire 121.

As the vibration hammer 141 is continuously operated in the lifting process, vibration and noise are excessively generated to hinder the work environment, and fatigue loads are accumulated in various structures of the heavy construction equipment lifting the compaction unit 140. There was a problem.

As described above, in order to solve the problem when the vibration hammer 141 is continuously operated in the lifting process, the vibration hammer 141 is temporarily stopped and the vibration hammer 141 is seated on the ground again after lifting the compaction unit 140 to the ground. Although there is a way to operate, there is a problem that the work speed is significantly reduced compared to the continuous operation of the vibration hammer 141 to repeatedly operate the stop and operation of the vibration hammer 141 in this way.

In order to solve the problem of the conventional compaction equipment 100, as shown in Figure 3, the compaction equipment is provided with a plurality of compaction rods 61 vertically and horizontally on the lower surface of the compaction plate 62 (hereinafter referred to as It is referred to as 'Prior Art 2' to minimize the flow of the compaction plate 62 and effectively fill voids existing between the grounds, but must be compacted when performing the compaction operation while sequentially moving the compaction plate 62. As the plate 62 has to be lifted and moved, the same problem as in the prior art 1 occurs.

In other words, if the vibration hammer 40 continues to operate even when the compaction plate is lifted, excessive vibration and noise are generated to impair the working environment, and fatigue is also caused by various structures of the construction equipment lifting the compaction plate 62. There is a problem that the load is accumulated.

As described above, in order to solve the problem when the vibration hammer 40 continues to operate in the lifting process, the vibration hammer 40 is temporarily stopped and the compaction plate 62 is seated on the ground, and then the vibration hammer 40 is lifted again. Although there is a way to operate, there is a problem that the work speed is significantly reduced compared to the continuous operation of the vibration hammer 40 to repeatedly operate the stop and operation of the vibration hammer 40 in this way.
