Description

Construction equipment for fiber reinforced soil structure

The present invention relates to a construction device using a reinforcing hole that stabilizes a slope by applying reinforcing soil to an unstable sloped area, and more specifically, by efficiently spraying reinforcing soil and long fibers on a slope, the long fiber and the reinforcing soil can make the stable structure of the sloped land. It relates to a device for constructing a fiber-reinforced soil to maintain.

The slopes left after embankment or cutting work are very unstable structurally, so if there is no separate reinforcement work, there is a very high probability of loss or collapse during rainfall or thawing. For this reason, more efficient and various methods of reinforcing methods and devices for reinforcing instability slopes have been developed.

For example, in Korean Patent Publication No. 10-2007-0020163, a device for constructing a fiber-reinforced soil method for stabilizing a slope by spraying long fibers together with a sandy soil to a reinforcement target site has been disclosed. The fiber, as it is ejected into the soil along with the water by riding on the flow of high-pressure jet water sprayed toward the reinforcement target site, is covered with a sandy soil in a state of being entangled on the inclined surface to stabilize the soil structure.

The apparatus for constructing a fiber reinforced soil includes a fiber supply device for continuously supplying fibers, a plurality of struts for supporting the supplied fibers, and a feed roller for tensioning the fibers at a required speed and supplying them to the ejector. The feed roller is a pulley for winding and moving the fiber, and its rotational speed is controlled by a driving motor.

However, the above-described conventional apparatus for constructing fiber reinforced soil has a problem that when the distance between the fiber supply device and the eject is far, the phenomenon that the fibers are entangled by blowing in the wind cannot be properly suppressed. (In fact, one of the technical difficulties of the fiber reinforced soil construction method is to prevent the entanglement of the fibers during transportation.) As a means to solve the above problem, the tension of the fibers is applied by applying a fiber feeder and feed roller with a fairly complicated structure. Although it was intended to maintain the tension, when the fibers are supplied over a long distance, the above-mentioned tension cannot be maintained to a significant degree. The reason is that fibers are often cut without breaking the tensile force.

In addition, during actual work, the spraying of water and fiber does not stop and does not proceed continuously, but is repeatedly stopped and re-ejected according to the working conditions, so the load on the fiber supply device is large, and the fibers are tangled inside the fiber supply device. Occasionally.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing the overall configuration of a fiber reinforced soil construction apparatus 10 according to an embodiment of the present invention.

Basically, the fiber-reinforced soil construction apparatus 10 according to this embodiment, which will be described later, is for reinforcing the slope of the construction target surface by spraying reinforcing soil and fiber yarns on the construction target surface (A), the control unit 11, and the reinforcement soil It has a configuration of a supply unit 12, a power supply unit 14, an air compressor 16, a water tank 16, a fiber yarn supply unit 20, a fiber yarn intermediate holder unit 30, and a terminal injection unit 40.

The reinforcing soil supply unit 12 is to transfer the prepared reinforcing soil to a required point through the reinforcing soil supply pipe 12d, that is, a point at which the end injection unit 40 is located, a hopper 12a and a plurality of conveyors 12b And, a pressure feeding pump 12c and a reinforcing soil supply pipe 12d. The pressure pump (12c) serves to pump the reinforced soil selected by the appropriate particle size to the construction target surface (A).

The generator 14, for example, produces 220 volts of power and delivers the generated power to the pressure pump 12c and the controller 11. The power transmitted to the controller 11 is converted to 12 volts and then applied to the end injection section 40 to enable the operation of the end injection section 40.

In addition, the compressed air produced by the air compressor 16 is transferred to the reinforcing soil supply unit 12 and the controller 11. Compressed air delivered to the controller 11 is appropriately branched, and is supplied to the fiber yarn supply unit 20, the fiber yarn intermediate holder portion 30, and the terminal injection portion 40.

Compressed air delivered to the fiber yarn supply unit 20 operates the locking actuator (23r in FIG. 4), and compressed air delivered to the fiber yarn intermediate holder unit 30 drives the stopping actuator (35 in FIG. 6). , Compressed air supplied to the end injection portion 40 is used to drive the rocking actuator (44 in FIG. 8) and the side actuator (48 in FIG. 10A).

In addition, the water stored in the water tank 18 is injected through the injection nozzle 45b through the injection rod 45 of the end injection portion 40 through the water supply hose 18a. The water sprayed through the spray nozzle 45b is sprayed to the target point of the construction target surface A along with the fiber yarns.

The controller 11 controls power and supply of compressed air and water, and may have, for example, the configuration of FIG. 11.

Referring to Figure 11, the controller 11 takes the form of a box with a handle 11k on its top, and on one side, a water pressure gauge 11a, a water pressure control valve 11b, an air pressure gauge 11c, It has an air pressure regulating valve 11d, a first manipulator 11e, a second manipulator 11f, and a power button 11g.

The water pressure gauge (11a), serves to display the pressure of the water toward the injection rod (45). Through the water pressure gauge 11a, the ejection pressure through the injection nozzle (45b in FIG. 8) can be grasped. In addition, the water pressure control valve 11b is to adjust the pressure of the water supplied to the injection nozzle 45b, and for example, it is possible to control the ejection pressure of the injection nozzle 45b by using the water pressure control valve 11b.

In addition, the air pressure gauge (11c) is a gauge showing the pressure of the air delivered to the plurality of actuators described above. Through the scale of the pneumatic pressure gauge 11c, it is possible to know the pressure currently being transmitted to each actuator. The air pressure regulating valve 11d is a valve for regulating the pressure of the air output from the controller 11. Of course, it is possible to adjust the operating speed of all pneumatic actuators using the air pressure regulating valve 11d.

The first manipulator 11e is a switch for separately operating the locking actuator 23r of the fiber yarn receiving case 21. In addition, the second manipulator 11f is a switch for separately operating the stopping actuator 35 of the fiber yarn supporter 31. The first manipulator 11e and the second manipulator 11f are applied to independently control the locking actuator 23r and the stopping actuator 35.

The power button 11g is a button that turns on and off the controller 11 itself.

Referring back to FIG. 1, it can be seen that the fiber yarn supply unit 20 includes four fiber yarn receiving cases 21. The fiber yarn receiving case 21 is to receive a fiber yarn (25 in FIG. 2) to be used for the fiber reinforced soil construction method, and takes the form of a dome.

2 is a partially enlarged perspective view of the fiber yarn receiving case 21 constituting the fiber yarn supply unit 20, and FIG. 3 is a perspective view for explaining the operation of the fiber yarn feeder 22 of FIG. 4 is a cross-sectional view showing the internal structure of the fiber fixing device 23 shown in FIG. 2.

As shown, the fiber yarn receiving case 21, a horizontal bottom portion (21a), a plurality of frame rods (21b) fixed to the top of the bottom portion (21a), and the frame rod (21b) It includes a support (21d) fixed to the upper end of the, the fiber fixing device (23) mounted to the support (21d), and a transparent cover (21c) surrounding the frame rod (21b).

First, the bottom portion 21a is a disc-shaped member having a width capable of receiving a plurality of fiber yarns 25 thereon, and is disposed horizontally on the ground. Each frame rod 21b is a curved pipe-like member, the lower end of which is fixed to the edge of the bottom portion 21a, and the upper end of the frame rod 21a is met by the support 21 through a vertical upper portion of the center of the bottom portion 21a. Are fixed against each other.

In addition, the fiber saider 22 is fitted to each frame rod 21b and fixed. The fiber saider 22 is a member that prevents the fiber yarns from tangling with each other by supporting a plurality of fiber yarns 25 that are pulled up to the upper portion of the receiving case 21 and takes the form of a disc having a certain thickness.

The fiber saider 22 has a frame fixing hole 22a and a guide hole 22b in an eccentric position. The frame fixing hole 22a is a hole through which the frame rod 21b passes. In addition, the guide hole 22b is a hole that passes through the fiber yarn and guides it upward. For example, the fiber yarns 25 unwound from the bobbin 25a pass upward through the fiber yarn fixator 23, which will be described later, in a state gathered centrally after passing through the guide holes 22b of each fiber yarnr 22.

The fiber saider 22 and the fiber yarn 25 are preferably arranged in the vertical direction. That is, the distance between the fiber saider 22 and the bobbin 25a is maintained as close as possible.

The transparent cover 21c is a flexible film surrounding the frame rod 21b as a whole and blocking the inner region of the frame rod 21b from the outside. Vinyl can also be used as the transparent cover 21c. The transparent cover 21c serves as a protective film that blocks dust or foreign substances from entering the fiber yarn case 21.

The support 21d is a metal plate having a certain thickness, and is fixed to the upper end of each frame rod 21b to fix the frame rods 21b to each other. The coupling method of the support 21d to the frame rod 21b may be welding.

In addition, a direction guider 24 is positioned on one side of the support 21d. The direction guider 24 includes a flexible arm 24b erected upward, and a support ring 24a provided at an upper end portion of the flexible arm 24b. The flexible arm 24b is a member that maintains a bent state when it is bent, and its lower end is fixed at an appropriate point of the frame mold 21b. The support ring 24a is a ring-shaped member that passes through the fiber yarn 25 therein.

The direction guider 24 serves to determine the initial direction of the fiber yarn 25 pulled upward from the fiber yarn receiving case 21. In most cases, the support ring 24a is located on the vertical top of the body block 23a.

On the other hand, the fiber yarn fixator 23 passes through the fiber yarn 25 while being fixed to the support 21d, and serves as a stopper to block the movement of the fiber yarn as necessary. For example, the operator operates the end injection portion 43 of the end injection portion 40 to operate at the moment when the injection of water and the fiber yarn is temporarily stopped, thereby blocking the movement of the fiber yarn 25. If the fiber yarn fixator 23 is not present, the fiber yarn 25 is, for example, blown by the wind and released from the fiber yarn case 21 to become tangled.

The fiber fixing device 23 has a body block 23a and a locking actuator 23r, as shown in FIG. 4. The body block 23a is a block member having a vertical passage 23b and a horizontal passage 23p therein, and its lower end enters the inner space of the fiber yarn receiving case 21.

The vertical passage 23b is a hole extending in the vertical direction, and passes through the fiber yarn 25 therein. The fiber yarn 25 is drawn out through the vertical passage 23b by the tensile force applied from the terminal injection portion 40 to be described later.

The horizontal passage 23b is a passage intersecting the vertical passage 23b, and is separated with the vertical passage 23b above. The left horizontal passage 23p in the figure is a female threaded sphere on which an internal thread is formed on its inner circumferential surface and has a capscrew 23d and a support cushion 23f.

The support cushion 23f is a member made of silicone or rubber, and serves to support the fiber yarn 25 when the pressure cushion 23g presses the fiber yarn 25 in the direction of the arrow f. When the fiber yarn 25 is squeezed between the supporting projection 23f and the pressing cushion 23g, tension to the outside is stopped.

The cap screw 23d is a tanned bolt and is used to move the support cushion 23f toward the pressure cushion 23g side. For example, when the support cushion 23f is worn, the support cushion 23f is moved in the direction of the vertical passage 23b.

The locking actuator 23r includes a cylinder 23h that receives air pressure from the outside through the air port 23n, and a piston rod that is accommodated inside the cylinder 23h and moves back and forth with respect to the support cushion 23f ( 23k), a pressure cushion 23g provided at the tip of the piston rod 23k, and a spring 23m elastically supporting the piston rod 23k. The piston rod 23k reciprocates under the pressure of compressed air applied through the air port 23n to determine the withdrawal and stoppage of the fiber yarn 25.

The fiber yarn receiving case 21 having the above-described configuration usually constitutes one set of four to constitute the fiber yarn supply unit 20.

The fiber yarn 25 drawn out from the fiber yarn supply unit 20 is directed to the end injection portion 40 through a plurality of fiber yarn supporters 31, as shown in FIG. The fiber yarn supporter 31 supports the fiber yarn 25 between the fiber yarn supply unit 20 and the terminal injection portion 40, for example, serves to prevent the fiber yarn from being stretched by blowing in the wind.

In addition, as will be described later, the fiber yarn supporter 31 functions as a stopper for stopping the fiber yarn 25 in motion, like the fiber yarn fixator 23 described above. In particular, the stopping operation of the plurality of fiber yarn supporters 31 occurs simultaneously. That is, when the worker temporarily stops the ejection of water and the fiber yarn by operating the terminal injection portion 43, the movement of the fiber yarn is simultaneously blocked. Several points of the fiber yarn 25 are fixed at the same time. By the fiber yarn supporter 31, the fiber yarn fixator 23, and the guide bar (47 of FIG. 8) to be described later, the fiber yarn 25 can always maintain a taut state in all sections regardless of whether it is moving or stopped.

FIG. 5 is a perspective view of the fiber yarn supporter 31 shown in FIG. 1, and FIG. 6 is a partial cross-sectional view of the fiber yarn supporter 31. 7A and 7B are diagrams for explaining the operating principle of the fiber yarn supporter 31.

As shown, the fiber yarn supporter 31 is fixed to the fixing column 32a extending vertically to be fixed to the ground, and horizontally fixed to the upper end of the fixing column 32a and perpendicular to the fiber yarn It includes a stopper case (33) to pass through, a stopper (34) horizontally installed on the upper portion of the stopper case (33), and a stopper actuator (35) for elevating movement of the lift stopper (34). .

The fixing column 32a is a hollow pipe-shaped member, and a lower end portion is sharply formed to be easily fixed to the ground. The fixed pillars 32a have various sizes. It is possible to simultaneously operate the fiber yarn supporters 31 having different heights. This is because, regardless of the terrain, the fiber yarn 25 should be kept as horizontal as possible.

The stopper case 33 is a member installed horizontally on the upper portion of the fixed column 32a through the support bracket 32b, and has a receiving groove 33c opened upward. The receiving groove 33c is a groove having a semi-circular bottom portion, and has a friction sheet 33c on the bottom surface. The friction sheet 33c is a plate-shaped member made of rubber or silicon and waits for the lowering of the elevating stopper 34 while being fixed to the bottom surface of the receiving groove 33c.

In addition, a plurality of side holes 33a are formed at both sides of the stopper case 33 in the width direction. The side hole 33a is a hole through which the fiber yarn 25 passes, and is a hole through which the fiber yarn 25 passes through the receiving groove 33b. The fiber yarn 25 passing through the side hole 33a passes through the lower portion of the lifting stopper 34. The fiber yarn 25 is fixed by being pressed by the lifting stopper 34 as shown in FIG. 7B as the lifting stopper 34 descends. When the lifting stopper 34 rises, the movement of the fiber yarn 25 starts again.

In addition, the stopper actuator 35 is a cylinder 35a fixed to the lower center of the stopper case 33 and the pressure of air installed inside the cylinder 35a and supplied through the air supply hose 16a. It includes a piston rod (35c) operated by, and a spring (35d) for elastically supporting the piston rod (35c) upward. The upper end of the piston rod 35c penetrates the bottom of the stopper case 33 upward and is fixed to the lifting stopper 34. It is natural that the lifting motion of the lifting stopper 34 is performed by the action of the stopping actuator 35.

As shown in Fig. 1, a plurality of fiber yarn supporters 31 having the above configuration are arranged in series at appropriate points. For example, it is fixed to the ground following the movement line of the worker. The spacing of the fiber yarn supporters 31 is not determined, but is determined according to the situation.

FIG. 8 is a partially cutaway perspective view showing the structure of the end injection unit 40 shown in FIG. 1, and FIG. 9 is for explaining an example of a mounting structure of the guide bar 47 in the end injection unit 40 It is an exploded perspective view. 10A and 10B are cross-sectional views for explaining the operating principle of the guide bar 47 shown in FIG. 9.

As shown, the end injection portion 40, the housing 41 having an internal space, and is supported in the housing 41 and extends in the longitudinal direction while being connected to the water supply hose 18a, and a plurality of injection nozzles 45b It includes a spraying rod (45) having a), a fixed arm (46) fixed to the outside of the housing (41), and a guide bar (47) fixed to the end of the fixed arm (46).

The housing 41 is carried by the operator and has handles 41a on both sides. The operator places the housing 41 in front of the user with the handle 41a held.

In addition, the inside of the housing 41 is provided with a timer 42, the operating portion 43 and the oscillating actuator 44. The timer 42 determines the speed or width of the swing motion of the arrow s direction of the injection rod 45 by adjusting the operation timing of the swing actuator 44.

The operation unit 43 is also an input unit for inputting a command to temporarily stop or resume spraying of water and fiber yarn, for example, as the operator operates at any time during the operation. When the spraying of water and fiber yarns is stopped through the control unit 43, the supply of water and fiber yarns is immediately stopped. In particular, the fiber yarn fixator 23, the fiber yarn supporter 31, and the guide bar 47 are fibers. The yarns 25 are held at the same time and fixed. Regardless of the distance of the fiber from the supply unit 20 to the end injection unit 40, the fiber yarn is always kept in a tight state over the entire distance and is stopped and resumed in that state.

A swivel connector 44f and a hose connecting tube 44c are provided inside the housing 41. The swivel connector 44f is a well-known part that connects the water supply hose 18a and the hose connection tube 44c, and supports the hose connection tube 44c to be axially rotatable.

The hose connection tube 44f is in communication with the injection rod 45 while being connected to the swivel connector 44f and supports the injection rod 45 horizontally. It is natural that the water supplied through the water supply hose 18a is supplied to the injection rod 45.

In addition, the hinge 44d is fixed to the upper edge of the hose connecting tube 44f. The hinge 44d is connected to the end of the piston rod 44b of the swinging actuator 44 and rotates axially clockwise and counterclockwise within a set range when the swinging actuator 44 is operated.

On the other hand, the injection rod 45 is a rod-like member having a flow path formed therein and an extended end blocked and extended horizontally, and has four injection nozzles 45b equal to the number of strands of the fiber yarn 25. The injection nozzle 45b is an injection means for spraying the water supplied through the water supply hose 18a and at the same time spraying the fiber yarn 25 fitted through the fiber yarn inlet 45a in the same direction as water. The fiber yarn 25 receives kinetic energy of water from the inside of the injection nozzle 45b and is ejected together with water.

The fixing arm 46 is a rod-shaped member fixed substantially perpendicular to the outside of one side of the housing 41, and serves to support the guide bar 47 in parallel with the injection rod 45.

In addition, a fixing groove 46a and a hole 46b are formed at an upper end of the fixing arm 46 so that the guide bar 47 can be fixed to the fixing arm 46. The hole 46b passes through the male screw portion 47c of the guide bar 47 as a through hole penetrating the fixing arm 46b. Further, the fixing groove 46a is a groove including a hole 46b in its inner region, and particularly has a tooth 46c on its inner circumferential surface. The tooth 46c meshes with the tooth portion 47b formed on the outer circumferential surface of the end of the guide bar 47.

In addition, a male screw portion 47c is positioned at an end of the guide bar 47. When the male screw portion 47c is inserted into the hole 46b and clamped with the fixing nut 47d from the opposite side, the coupling of the guide bar 47 to the fixing arm 46 is achieved.

The application of the teeth 46c and the teeth 47b as described above is for adjusting the directionality of the fiber through holes 47a formed in the guide bar 47. That is to say, if necessary, to change the direction of the imaginary straight line passing through the fiber through hole 47a. In other words, it is for fixing the guide bar 47 in a state rotated in the direction of the arrow w or vice versa.

In fact, when the altitude difference between the point where the last fiber yarn supporter 31 is located and the location where the worker is located is severe, the degree of bending of the fiber yarn 25 passing through the guide bar 47 increases, and a tensile force applied to the fiber yarn is applied. Since it is possible to loosen the nut 47d and align the direction of the fiber through hole 47a similarly to the moving direction of the fiber, it is possible to prevent the above-mentioned increase in tensile force.

On the other hand, as shown in Figure 10, the guide bar 47 also has a stopper function capable of temporarily stopping the fiber yarn 25.

10A and 10B, the guide bar 47 has a configuration including a hollow pipe type extension tube 47e, a sliding stopper 47k, and a side actuator 48.

The extension tube 47e has a certain inner diameter and extends in the longitudinal direction and has a plurality of fiber through holes 47a through which the fiber yarns 25 pass. The imaginary straight line passing through the center of the fiber through hole 47a intersects the central axis of the extension tube 47e.

In addition, the sliding stopper 47k is a circular rod-shaped member installed inside the extension tube 47e, and is a member that can slide in the longitudinal direction of the extension tube 47e while being accommodated inside the extension tube 47e. The outer circumferential surface of the sliding stopper 47k is in contact with the outer circumferential surface of the extension tube 47e.

In addition, a plurality of through holes 47m are formed in the sliding stopper 47k. The through hole 47m is a hole corresponding to the fiber through hole 47a formed in the extension tube 47e on a one-to-one basis. As the sliding stopper 47k moves linearly inside the extension tube 47e, the plurality of through holes 47m are aligned with the fiber through holes 47a to be opened or shifted at the same time and blocked at the same time.

The side actuator 48 is coupled to the end of the sliding stopper 47k while being fixed to the fixed arm 46, and reciprocates the sliding stopper 47k in a linear direction.
