Description

Technical Field [0001] The present invention relates to a construction method for spreading a ground stiffener,

More particularly, the present invention relates to a method for installing a soft ground reinforcement material, and more particularly, to a method of constructing a soft ground reinforcement material by minimizing the earth pressure on a soft ground using two or more weight- And the method of installing and installing the soft ground reinforcement.

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.

[

The length of the lower conveyor 800 may be longer than the length of the upper conveyor 700 and the ends of the upper conveyor 700 and the lower conveyor 800 may be arranged side by side. A gap margin of a predetermined length may be generated.

The hopper 600 is disposed in the rear area of the lower conveyor 800 and feeds the ground reinforcement material A supplied from the conveying conveyor 300 to the upper conveyor 700 and the lower conveyor 800, As shown in FIG.

The upper conveyor 700 of the installation part 500 is provided with a third high-speed motor and a fourth high-speed motor which are capable of rotating at high speeds by hydraulic pressure, pneumatic or electric signals at both ends, A third pulley 702 and a fourth pulley 704 are arranged and meshed with the third pulley 702 and the fourth pulley 704 to rotate in accordance with the rotation of the third pulley 702 and the fourth pulley 704, And a second belt portion 720 that is rotated by the second belt portion 720.

The second support plate 706 is provided with at least one pressurizing conveyance passage 706 for guiding the pressurization of the ground reinforcement material A which is forwardly pushed through the pressurization space between the upper conveyor 700 and the lower conveyor 800 as it is rotated. Rollers 710 may be installed.

When the ground reinforcements A are forwardly fed through the press-feeding space, that is, when the top conveyor 700 and the bottom conveyor 800 are rotated in the forward and rearward directions, A cover 730 may be provided to prevent splashing by the repulsive force.

On the other hand, the lower conveyor 800 of the installation part 500 is provided with a fifth high-speed motor and a sixth high-speed motor which are capable of rotating at high speeds by hydraulic pressure, pneumatic or electric signals at both ends, 5 pulley 802 and a sixth pulley 804 are arranged and meshed with the fifth pulley 802 and the sixth pulley 804 so that the fifth and sixth pulleys 802, And a third belt portion 810 that rotates in an orbital manner.

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 Which will be described below with reference to FIGS. 1 to 10. FIG.

FIG. 7 is a side view schematically showing a state in which an installation angle of a ground reinforcement is changed according to an upward and downward angle of an installation portion of an installation device used in a method of installing and installing a soft ground reinforcement according to the present invention, FIG. 6 is a plan view showing a state in which the installation direction of the ground reinforcement is varied as the installation portion of the ground reinforcement material installation apparatus according to the embodiment of the present invention is adjusted in the lateral direction.

Figs. 9A and 9B are enlarged views of the installation portions of Figs. 4A and 4B for explaining the installation principle of the ground reinforcement. Figs. 10A and 10B are views for explaining the control relationship of the ground reinforcement installation apparatus 100 according to the embodiment of the present invention Fig.

As shown in FIG. 7, the installation device 100 used in the method of installing and installing the soft ground underground stiffener according to the present invention is characterized in that, in a state where it is placed on the soft ground for laying the ground stiffener A, The ground reinforcement (A) can be installed at a 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.

7, when the operator inputs the setting angle of the installation unit 500, the control unit 1000 applies an operation signal to the elevating actuator 980, and accordingly, the elevating 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.

8, 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 applies the operation signal to 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 installation device 100 used in the method of installing and installing the soft ground underground stiffener according to the present invention has the advantage that the ground reinforcement A can be selected and installed in a desired direction.

Referring to FIGS. 9A and 9B, the principle of the operation of installing the ground reinforcement A using the installation apparatus 100 used in the method of installing and installing the soft ground underground reinforcement according to the present invention will be described.

As described above, in the installation device 100 used in the method of installing and installing the soft ground underground stiffener according to the present invention, the installation part 500 for injecting the ground reinforcement at a predetermined speed is installed between the upper conveyor 700 and the 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 control unit 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 part 500 of the installation device 100 used in the method of installing and installing the soft ground foundation stiffener according to the present invention is constructed such that the upper conveyor 700 and the lower conveyor 800, the volume of the press-feeding space can be increased or decreased. Therefore, the injection angle of the ground reinforcement can be adjusted by adjusting the volume of the press-feeding space.

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.

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.
