The present invention relates to a rotary screw and a hydraulic cylinder compaction-free vibration-free construction equipment for improving the soft ground, and more particularly to the environment by constructing the reinforcing member pile formed in the ground with no vibration and noise for the purpose of improving the soft ground. Rotation screw and hydraulic-cylinder type compaction to relieve the cause of the problem and to improve the soft ground to secure a comfortable living environment in the surrounding area. Non-vibration anti-noise (hereinafter referred to as "RHN").

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 in a vertical direction 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 into the ground through the vibration of the casing 12. 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 of compacting sand or crushed stone which is supplied to the inside of the furnace by the load of the casing and the hopper through repeated vertical movement of the cylinder device. In addition, this also has a disadvantage in that noise and vibration are generated due to the impact generated during the lowering operation of the casing and the hopper, such as a vibration hammer.

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, so that a mechanical bunch of the cylinder device is generated. To provide a cause of durability 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,

It is an object of the present invention to break away from the vibration method of the conventional vibration hammer to form a rotating screw which is lowered by the operation of the hydraulic cylinder at the same time as the rotation of the inside of the casing to press the reinforcement member downward so as to discharge and compaction It is to provide a rotary screw and hydraulic cylinder compaction-free vibration-free construction equipment for improving the soft ground to prevent the cause of the vibration and noise in advance because there is no need for a separate vibration and shock drive means.

Another object of the present invention is a simple screw structure and the overall configuration for the discharge and compaction of the reinforcing member is integrated, the rotary screw and hydraulic cylinder compaction type to improve the soft ground to maximize the efficiency and work efficiency in construction It is to provide a vibration-free noiseless construction equipment.

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 120 can be inserted and drawn into the ground through the spiral rotation, and 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).
