Description

[0001] Apparatus for spreading of ground stiffener [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ground reinforcement material installation device, and more particularly, to a ground reinforcement material installation device capable of uniformly laying a ground reinforcement material on a soft foundation with minimized weight,

In general, when the soft ground is improved by the dewatering method, the ground is improved by using the large equipment of approximately 50 to 150 ton class, and the drain is inserted to improve the ground. As in the case where the ground is marine clayey soil or buried with marine clayey soil, In case of the ground, it is impossible to enter the equipment, and it is necessary to take measures for entering the equipment.

As a precautionary measure for entering the equipment, the soil covering method using the wetland dozer and the surface layer solidification method are mainly used.

In the method of covering the soil using the wetland dozer, the geotextile is placed on the top of the soft soil layer, and then the soil is laid to a predetermined thickness by repeating several times about 50 cm at a time using a small wetland dozer.

However, in such a method, as the soil is repeatedly run on the soft soil layer, the soil is deformed or the soft soil layer is pushed due to the weight of the dozer and the vibration due to frequent repetitive running, However, in case of installing a relatively long distance, there is a problem that the risk of overturning of the drainage equipment is increased due to the accumulation of the juncture of the soft layer, and the geotextile is blown up and the soil is difficult due to the delayed penetration.

In addition, the use of a small-sized doser having a small work capacity is inevitable, and there is also a problem that the installation cost of the gravel is large.

On the other hand, the surface layer solidifying method is a method of increasing the strength by injecting and mixing cement or the like only into a certain portion of the upper part of the soft soil layer. This method is expensive because the construction cost is high and the soil between the solidified layer and the soft soil layer There is a problem that there is an adverse effect in the improvement of the lower soft soil layer which is a subsequent process due to irregular load transmission due to different characteristics.

At this time, the third support plate 806, the fifth pulley 802, and the sixth pulley 804 can be adjusted in the forward and backward directions by the spacing adjusting member (not shown) It is possible to adjust the tension of the belt 810.

The upper conveyor 700 and the lower conveyor 800 can adjust the volume of the pressure conveying space as the vertical spacing is adjusted by the throttle part 900. [

The throttle portion 900 includes a support 910 having one end fixed to the third support plate 806 of the lower conveyor 800 and the other end having a gap adjusting groove 920 in the longitudinal direction, And a latching protrusion 930 protruding from the second support plate 706 of the support plate 700 and capable of moving on the gap adjusting groove 920 of the support 910.

Here, the second support plate 706 of the upper conveyor 700 may be configured to be lifted or lowered by a lifting device (not shown) or may be manually lifted and fixed.

For example, in the embodiment of the present invention, the latching protrusion 930 is formed on the upper conveyor 700. However, when the latching protrusion 930 is installed on the lower conveyor 800, The adjustment groove 920 may be disposed on the lower conveyor 800 side so that the lower conveyor is elevated.

When the upper conveyor 700 is moved up and down with respect to the lower conveyor 800, the latching protrusion 930 of the upper conveyor 700 flows on the gap adjusting groove 920 of the support 910 And the volume of the press-feeding space can be increased or decreased. As a result, the amount of installation of the ground reinforcement material A can be adjusted.

The inclined portion 500 can adjust the angle of inclination of the ground reinforcement A with respect to the soft ground as the angle is adjusted in the vertical direction or the angle is adjusted in the lateral direction.

That is, the swing actuator 950 is installed on both the front side of the base plate 400 and the third support plate 806 of the lower conveyor 800 by the connection bracket 960 and the first hinge bracket 970 The connection bracket 960 and the third support plate 806 of the lower conveyor 800 are respectively installed by the second hinge bracket 990 so that the installation part 500 is capable of adjusting the forward and backward angles and the left and right angles Will be described with reference to FIGS. 1 to 8. FIG.

FIG. 5 is a side view schematically showing a state in which the installation angle of the ground reinforcement is varied according to the upward and downward angles of the installation portion of the ground reinforcement installation apparatus according to the embodiment of the present invention. FIG. Is a plan view showing a state in which the installation direction of the ground reinforcement material is changed according to the lateral adjustment of the installation portion of the ground reinforcement material installation device according to the present invention.

Figs. 7A and 7B are enlarged views of the installed portions in Figs. 2A and 2B for explaining the installation principle of the ground reinforcement. Figs. 8A and 8B show the control relationship of the ground reinforcement installing apparatus 100 according to the embodiment of the present invention Fig.

5, the ground reinforcement material installation apparatus 100 according to the embodiment of the present invention includes a ground reinforcement material A placed on a soft foundation, a ground reinforcement material A disposed on a soft foundation for laying the ground reinforcement material A, Can be set as the set distance by the set amount.

That is, when the operator sets and inputs the amount of the ground reinforcement, the control unit 1000 can adjust the amount of opening of the opening 222 by applying an input signal to the opening / closing actuator 230 of the storage hopper 200.

For example, when a relatively large amount of the ground reinforcement is to be installed, an operation signal is applied to the opening / closing actuator 230 to increase the amount of opening of the opening 222, It is preferable that an operation signal is applied to the opening and closing actuator 230 to allow the opening amount of the opening 222 to be increased So that a small amount of the ground reinforcement material can be introduced from the storage hopper 200 into the input hopper 600. [

In this way, with the amount of the ground reinforcement being determined, the operator adjusts the vertical angle of the installation part 500 in accordance with the installation position of the ground reinforcement, that is, the distance to be installed, and then the ground reinforcement is installed.

5, when the operator inputs the setting angle of the installation unit 500, the control unit 1000 applies an operation signal to the elevation actuator 980, and accordingly, the elevation actuator 980, Is raised and lowered at an angle corresponding to the input signal.

That is, as the length of the lifting actuator 980 is increased by hydraulic, pneumatic or electric signals, the second supporting plate 706 coupled with the second hinge bracket 990 is moved up and down. At this time, The first hinge bracket 706 can be angularly displaced from the connecting portion with the first hinge bracket 970 as the starting point.

Accordingly, the closer the angle of the installation part 500 is to the vertical, the shorter the installation distance of the ground reinforcement. The closer the angle of the installation part 500 is to the horizontal, the longer the installation distance of the ground reinforcement becomes. The installation distance of the ground reinforcement material A can be adjusted by adjusting the angle of the ground reinforcement material 500.

On the other hand, the operator may adjust the left and right angles of the installation unit 500 in accordance with the installation direction of the ground reinforcement, that is, the direction in which the ground reinforcement is to be installed, and then the ground reinforcement may be installed.

6, when the operator inputs the setting direction of the placement unit 500, the control unit 1000 applies an operation signal to the swing actuator 950, and accordingly, the swing actuator 950, The swing is performed at an angle corresponding to the input signal.

That is, as the lengths of the swing actuator 950 on both sides are extended or reduced by hydraulic, pneumatic or electrical signals, the connecting bracket 960 and the second supporting plate 706 coupled with the first hinge bracket 970 The direction can be changed as the swing takes place.

At this time, among the pair of swing actuators 950 provided on both sides, the swing actuator 950 positioned on the side of the installation direction is reduced in length, and the swing actuator 950 located in the opposite direction is extended The direction of the swing can be determined according to the swing.

Therefore, the apparatus 100 for installing a ground reinforcement according to an embodiment of the present invention has an advantage that the ground reinforcement A can be selected and installed in a desired direction.

7A and 7B, the principle of the operation of installing the ground reinforcement material A using the apparatus 100 for installing a ground reinforcement material according to an embodiment of the present invention will be described.

As described above, in the apparatus 100 for installing a ground reinforcement according to an embodiment of the present invention, an installation part 500 for injecting a ground reinforcement at a predetermined speed includes an upper conveyor 700 and a lower conveyor 800 .

That is, it is possible to control the rotational speeds of the upper conveyor 700 and the lower conveyor 800 so as to perform the spraying by the repulsive force, instead of injecting the ground reinforcement by pneumatic, hydraulic, will be.

Accordingly, the upper conveyor 700 and the lower conveyor 800 are provided with a second belt portion 720 applied to each belt portion, that is, the upper conveyor 700, and a third belt portion 810 applied to the lower conveyor 800 Speed motors for high-speed rotation are applied.

In the case of the upper conveyor 700, the third and fourth high-speed motors and the third pulley 702 and the fourth pulley 704, which are rotatably driven at high speed by the input signal, are disposed on both ends, The fifth and sixth high-speed motors and the fifth pulley 802 and the sixth pulley 804, both of which are rotatable at a high speed by input signals, are disposed on both ends.

Accordingly, when the third and fourth high-speed motors are rotated at a high speed by the input signal of the controller 1000, the third pulley 702 and the fourth pulley 704 are also rotated at a high speed, 720) Also, high-speed rotation is performed in an infinite orbital manner.

When the fifth and sixth high-speed motors are rotated at a high speed by the input signal of the controller 1000, the fifth pulley 802 and the sixth pulley 804 are rotated at a high speed, 810) are also rotated at high speed in an infinite track manner.

At this time, a pressure conveying space spaced apart from the upper conveyor 700 by a predetermined distance is formed between the upper conveyor 700 and the lower conveyor 800, and the ground reinforcement A injected from the input hopper 600 is passed through the pressure conveying space. The ground reinforcement material A passing through the press-feeding space has a frictional force between the second belt portion 720 of the upper conveyor 700 and the third belt portion 810 of the lower conveyor 800, I.e., in the forward direction.

At the same time, the ground reinforcement A is more stably forwardly fed to the upper conveyor 700 by the rotational force of the plurality of feeding rollers 710 provided in the second supporting plate 706, thereby improving the efficiency of jetting .

For reference, it is preferable that the upper conveyor 700 and the lower conveyor 800 constituting the installation part 500 are rotated at a high speed at a high speed. In some cases, the conveyor speed of one conveyor may be higher than that of the other conveyor So that the injection angle of the ground reinforcement can be made different.

For example, as the rotation speed of the upper conveyor 700 is made higher than that of the lower conveyor 800, the injection angle of the ground reinforcement is lowered by a certain angle as compared with the case of the constant speed, As the rotational speed of the upper conveyor 700 is made slower, the injection angle of the ground reinforcement can be increased by a certain angle as compared with the case where the speed is constant.

The installation portion 500 of the ground reinforcement material installation apparatus 100 according to the embodiment of the present invention is constructed such that the gap between the upper conveyor 700 and the lower conveyor 800 is adjusted by the throttle portion 900 The volume of the press-feeding space can be increased or decreased, so that the injection angle of the ground reinforcement can be adjusted by adjusting the volume of the pressure-feeding space thereof.

For example, when the upper conveyor 700 is raised, when the latching protrusion 930 is engaged with the lower part of the gap adjusting groove 920 formed in the support 910 of the throttle part 900, the volume of the pressure- A large amount of the ground reinforcement material can be injected and deployed, so that the injection angle can be made relatively small.

Conversely, when the upper conveyor 700 is lowered and the latching protrusion 930 is hooked on the upper side of the gap adjusting groove 920 formed in the support 910 of the throttle portion 900, the volume of the pressure transmitting space is reduced, Since a small amount of ground reinforcement can be injected and deployed, the injection angle can be relatively large.

9 is a perspective view of a ground reinforcement installation apparatus according to another embodiment of the present invention, FIG. 10 is a side view of FIG. 9, and FIG. 11 is a view showing a state in which the upper conveyor of the installation section is moved forward Fig. 12 is a side view of Fig. 11. Fig.

9 to 13, the same reference numerals are assigned to the same parts as those of the above-described placement apparatus in the above-described ground reinforcement material installation apparatus 100 according to another embodiment of the present invention. And a repeated explanation will be omitted.

9 and 10, in an installation device 100 according to another embodiment of the present invention, the lower conveyor 800 of the installation part 500 is disposed in the front And may be installed so as to protrude longer than the upper conveyor 700 in the direction in which the ground reinforcement material A is installed.

Here, the upper conveyor 700 of the installation part 500 may be configured to be movable in the longitudinal direction with respect to the lower conveyor 800. [

That is, the upper conveyor 700 of the installation unit 500 is provided with a support rod 1100 in both the lateral directions of the second support plate 706, and the support rods 1100 are arranged in parallel Forward and backward along the guide rails 1200, that is, in the direction in which the ground reinforcement is installed.

Here, conventionally known reciprocating means may be applied such that the supporting rod 1100 moves in the installation direction along the guide rail 1200, for example, by hydraulic pressure, pneumatic pressure or electric signal. A description thereof will be omitted.

Therefore, if the upper conveyor 700 of the installation part 500 is moved to the front end side of the lower conveyor 800, the entire length of the installation part 500 becomes longer, and the ground reinforcement A is injected more remotely To be installed.

In this case, when the upper conveyor 700 is moved to the leading end side of the lower conveyor 800, the upper portion of the lower hopper 600 is opened between the hopper 600 and the upper conveyor 700, The ground reinforcements that are transferred to the pressurized space due to rotation may bounce through the open upper portion due to the repulsive force due to the rotational force, thus causing a fear of loss.

Therefore, it is preferable that a cover film 1400 that can be folded is provided between the rear end of the cover 730 of the upper conveyor 700 and the front end of the loading hopper 600.

The front end of the covering film 1400 is provided on the top end side of the loading hopper 600 with a covering film accommodating portion 1300 maintaining the state in which the covering film 1400 is fitted by a torsion spring or the like, The rear end of the cover 730 of FIG.

11 and 12, when the upper conveyor 700 is moved to the leading end side of the lower conveyor 800, the upper conveyor 700 is engaged with the covering film accommodating portion 1300 according to the movement of the upper conveyor 700 And the upper space between the loading hopper 600 and the upper conveyor 700 is shielded while the covering film 1400 having the curtain 1400 is loosened so as to suppress the loss of the ground reinforcement material A conveyed by the lower conveyor 800 .

9 and 10, when the upper conveyor 700 is moved to the rear end side of the lower conveyor 800 and is positioned adjacent to the loading hopper 600, the covering film 1400 covers the covering membrane And can be retracted by the elastic restoring force of the torsion spring installed in the portion 1300, and can be drawn into the shielding film accommodating portion 1300. [

FIG. 13 is a side view showing a state in which the lower conveyor of the installation part is spaced rearward in FIG. 10; FIG.

Referring to FIG. 13, the lower conveyor 800 has a structure in which the third support plate 806 is formed of a telescopic type or a block type in which the length is variable.

Therefore, the length of the lower conveyor 800 can be reduced so that the top ends of the lower conveyor 800 are parallel to each other in a state where the upper conveyor 700 is adjacent to the loading hopper 600.

That is, when the third support plate 800 of the lower conveyor 800 is of the telescopic type, the length thereof is reduced by folding, and when the third support plate 800 is a block type, the length of the third support plate 800 can be reduced.

In this case, a plurality of third guide rollers 808 are installed on the lower conveyor 800, and after the length is adjusted, the third guide rollers 808 are fixed to the third support plate 806 And the third belt portion 810 may be replaced with another belt having a different length.

Therefore, as the lower end of the lower conveyor 800 of the installation part 500 is reduced in length, the leading end of the lower conveyor 800 is parallel to the leading end of the upper conveyor 700, So that it can be installed while spraying the ground reinforcement material A at a relatively short distance.

As described above, the ground reinforcement material installation apparatus 100 according to another embodiment of the present invention can change the entire length of the installation unit 500, so that the position where the ground reinforcement material A is to be installed, It is possible to place the ground reinforcement material A in conformity with the present invention, and the efficiency of the installation can be greatly improved.

In the following description of the ground reinforcement material installation apparatus according to another embodiment of the present invention, the configuration and operation relationship in which the installation unit 500 adjusts the angle in the vertical direction and the angle in the horizontal direction is not separately described, It is needless to say that the same as in the embodiment can be achieved by the same constitution of the installation part 500 for adjusting the angle in the vertical direction and adjusting the angle of the left and right direction as well as the installation amount of the ground reinforcement to be installed.

In other words, the ground reinforcement material installation apparatus 100 according to another embodiment of the present invention differs from the ground reinforcement material installation apparatus according to the previous embodiment only in that the length of the installation section 500 is variable, And operation relationship, and the effect of the operation are the same.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
