"").

In general, the construction equipment 10 for improving the soft ground includes an endless tracked vehicle 1 equipped with a wide track as shown in FIG. 1, and a leader formed vertically in front of the endless tracked vehicle 1. 2) and a casing 12 having a shoe 11 which is lifted up and down in the longitudinal direction of the leader 2 and which can be opened and closed at a tip thereof, and is formed on the casing 12 to be sand or crushed stone and mixed. Hopper 13 for supplying a reinforcing member such as aggregate into the casing 12, and formed on the hopper 13 to generate a penetration and compaction action in the ground through the casing 12 through vibration It consists of a vibration hammer 14.

As described above, the construction equipment 10 for improving the soft ground is characterized by the vibration and compaction action generated by activating the vibration hammer 14 to repeatedly insert and pull the casing 12 into the ground to reinforce the member file. The construction is to improve the soft ground, and as a result, the construction quality and the work efficiency of the soft ground is determined according to the capacity and efficiency of the vibration hammer (14).

However, since the vibration hammer 14 uses a strong vibration force, severe vibrations and noises are generated during the construction process, which in turn causes enormous obstacles to economic activities and personal life of neighboring residents, and in severe cases, cracks in buildings. As a result, domestic and domestic animals have died, causing many restrictions such as delays in construction due to complaints.

In addition, when compacting a reinforcing member having a constant volume, such as crushed stone and mixed aggregate, by vibrating force of the vibration hammer 14, the ground may be disturbed and dispersed due to severe impact and vibration, and thus, sufficient compacting effect of the reinforcing member may not be obtained. Problems have arisen.

Therefore, recently, as a way to solve the above problems

Ogawa penetrating and rising into the soft ground by the driving of the motor, a casing located inside the OGA and the sand or crushed stone is lowered through the vertical movement and connected to the casing and connected to the sand or crushed stone A hopper provided to the casing, a cylinder device connected to the casing to drive the casing up and down, and a motor for injecting the organo through forward rotation and raising the organo through reverse rotation; Registered as a Korean Patent Registration No. 0380798, "Low Vibration Low Noise Granular Pile Construction Apparatus for Improving Soft Ground", characterized by compacting the lowered sand or crushed stone with at least the load of the casing and the hopper through free fall of the casing. It has been.

However, the conventional "low vibration and low noise granular pile construction device for improving the soft ground" has a structure in which sand or crushed stone is supplied to the inside of the oga by raising and lowering the casing and the hopper by the vertical motion of the cylinder. Like the vibration hammer, noise and vibration are generated due to the impact generated during the elevating operation of the casing and the hopper.

In particular, the conventional "low vibration and low noise granular pile construction device for improving the soft ground" is a structure in which the casing and the hopper, which is a heavy object, only move up and down by the cylinder device. It provides the cause of degradation and failure.

In addition, the conventional "low vibration and low noise granular pile construction device for improving the soft ground" increases the overall volume and load due to the casing, hopper, and cylinder device, and not only decreases the construction efficiency due to the reduced mobility of the equipment. Changes in the center of gravity have frequently resulted in safety accidents in which the machine fell in one direction.

Therefore, the present invention has been made to solve the above conventional problems,

Another object of the present invention is the internal screw compaction vibration-free noiseless construction to improve the soft ground to simplify the structure and to integrate the overall configuration for the discharge and compaction action of the reinforcing member to maximize the efficiency and work efficiency in construction To provide the equipment.

Still another object of the present invention is to determine the pitch and width of the inner screw formed on the inner periphery of the casing according to the purpose and working environment of the present invention to efficiently control the discharge speed and the compaction range of the reinforcing member construction quality And to provide an internal screw compaction type vibration-free noise-free construction equipment for improving the soft ground to improve the work efficiency.

When described in detail by the accompanying drawings, the configuration for achieving the object of the present invention as described above are as follows.

Figure 2 is a cross-sectional view showing an embodiment of the internal screw compaction type vibration-free noise-free construction equipment for improving the soft ground of the present invention,

And a motor gear 131 which is engaged with the motor 130 to rotate the forward and reverse rotations of the casing 110 and the upper part of the casing 110 to form the reinforcing member A. Hopper 140 for supplying the inside of the 110, and the casing 110 Rotatably supported and comprises a frame 150 for securing the motor 130 and the hopper 140.

The tracked vehicle 1 may be moved and rotated according to the intrusion and drawing construction position of the casing 110 and is configured to minimize the ground pressure of the equipment to secure mobility when entering the tracked track in the present invention. The vehicle 1 includes a driver's seat and a power unit that rotate 360 ° around the wide track to control the positions of the leader 2 and the casing 110 according to the change in the construction position of the reinforcing member A pile. In addition, it is possible to secure stability when entering the equipment by minimizing the ground pressure by mounting a wide track.

In this case, the wide track is preferably a wetland shoe plate having a triangular cross section to improve traction when considering the characteristics of the soft ground and the working environment.

On the other hand, the casing 110 is a screw 112 is formed on the outer circumference and the forward and reverse rotation in accordance with the rotation direction of the motor 130 while the spiral and rotation through the spiral can be inserted into the ground and drawing out the noise and Vibration does not occur.

At this time, the inside of the casing 110 to form an inclined weight (not shown) in order to measure the input amount of the reinforcing member (A) so that the operator can check or output this can adjust the input amount of the reinforcing member (A). However, since the structure (drawing) and the operation principle of measuring the input amount of the reinforcing member (A) is a well-known technique that is commonly used in the art, detailed description thereof will be omitted.

In addition, at the distal end of the casing 110, as shown in FIG. 3, a larger diameter casing 110a is formed than the diameter of the casing 110, which is a work efficiency and reinforcement of the casing 110 penetrating into the ground. It is a structure for improving the discharge efficiency of the member A.

To this end, in the present invention, the diameter of the casing 110 is formed to about 500 mm and the diameter of the enlarged casing 110a is about 600 mm and the length is 1 to 2 m.

In addition, a plurality of air supply pipes may be formed inside the casing 110 to supply compressed air, which prevents the problem of inflow of soil into the casing 110 due to earth pressure in the ground and at the same time. (110) When the reinforcing member (A) inside it is not discharged in the downward direction is configured to efficiently discharge it.

The inner screw 120 is a very important configuration in the present invention, for discharging the reinforcing member A introduced into the casing 110 in a downward direction or to perform a compaction action, that is, the casing ( The reinforcing member A, which is introduced into the interior of the container 110, is forced and discharged downward through the spiral rotation.

Therefore, the inner screw 120 is rotated at the same time according to the rotation of the casing 110 without the need for a separate drive means to efficiently discharge and compact the reinforcing member (A) supplied to the inside of the casing 110 with no vibration and noiseless It becomes possible.

In particular, the inner screw 120 is preferably formed so as to be wound in a direction opposite to the screw 112, which causes the inner screw 120 to rotate forward when the screw 112 reverses for drawing. Therefore, the reinforcing member (A) supplied to the inside of the casing 110 can be forcibly discharged downward.

At this time, the inner screw 120 can be manufactured by adjusting the inner screw pitch (a), as shown in Figure 4, which rotates the inner screw 120 more quickly than the rotation of the screw 112 reinforcement member To increase the emissions and compaction of (A).

On the other hand, the inner screw 120 may be formed such that the width gradually increases from the top to the bottom in the cross-section as shown in Figure 5, which is the close area of the reinforcing member (A) and the inner screw 120 By increasing the pressure in the downward direction and at the same time to increase the compacting action of the reinforcing member (A).

As such, the inner screw 120 can be applied to the drain method by efficiently discharging the reinforcing member (A) in the downward direction at the same time as the rotation, and also applying the reinforcing member (A) to the compaction method through the discharge and compaction action You can do it.

On the other hand, the motor 130 is a configuration for generating a driving force to enable the injecting and drawing out of the vibration-free noise by rotating the casing 110 forward and reverse, wherein the motor 130 is both sides of the casing 110 The rotary gear 113 is formed to be engaged with each other in the direction to ensure smooth rotation of the casing 110, as well as the load is transmitted in one direction during the rotation process, so that the rotary gear 113 and the motor gear 131. This is to prevent the problem of being damaged in advance.

The hopper 140 is provided with an on-off valve 141 and an air supply nozzle 142, which is supplied or blocked by the compressed air into the hopper 140 to operate the opening valve 141 via the hinge axis. The input amount of the reinforcing member A is controlled.

On the other hand, the wire rope 151 is formed on the upper portion of the frame 150 and connected to the tracked vehicle 1 is moved up and down along the leader (2).
