Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a construction technique of an anchor work for reinforcing a hillside beside a road formed through a mountain or a concrete slope provided for revetment of a sea, a river or a dam. In particular, it is an object of the present invention to provide a drilling method for a concrete slope reinforcement anchor having a novel structure capable of efficiently performing drilling work by a small number of people, and a method for drilling a concrete slope reinforcement anchor using the same. .

[0002]

2. Description of the Related Art Slope artificially formed for roads, tunnels, seas, rivers, dams, etc., even if constructed by proper design and construction, is subject to rainwater or running water. Erosion, weathering, freezing and thawing, or crustal deformation
Due to natural phenomena, the geology and the actual condition of the slope gradually change, and the peeling phenomenon occurs between the concrete slope and the ground, preventing the expected strength from being obtained.
There is a risk that the entire slope may collapse, and in order to improve and stabilize such a slope, as a slope shaping machine, reshape the slope again or construct an anchor work. It is necessary to tens and establish the slope.

[0003] Generally, as a concrete slope reinforcement structure, a lattice-like concrete frame for securing the strength is formed, and a cross section of the relatively high-strength concrete slope is formed at a predetermined depth in the ground. An anchor is used in which a hole is reached, a predetermined anchor member is inserted, mortar is injected, and the concrete member is supported on the underground rock by the anchor member.

[0004] The anchor work on this slope is always a drilling work on an inclined surface, and is often carried out under location conditions where it is impossible to introduce a large construction machine. However, this hand-held pneumatic rock drill is mainly intended for use on flat terrain, and its own weight in the drilling direction is effectively weighted. Therefore, it is designed so that a predetermined drilling is performed. Therefore, in the case of the above-described inclined surface, a necessary and sufficient load is obtained in the drilling direction (that is, the direction vertical to the inclined surface). Not be able to provide a reaction force for drilling by pressing down on the slope of concrete by a few workers,
Because it is a work that gathers in a place with a poor scaffold and in a narrow place, even though it has a lifeline, its danger is extremely high, and furthermore, it becomes a harsh work while being exposed to destruction powder In addition to the poor scaffolding, the movement of mechanical equipment to the drilling point is also inefficient due to the movement of dragging the power air hose, and the performance of the handheld pneumatic rock drill itself is limited. Although the number of holes that can be drilled per day depends on the depth and the quality of the bedrock, practically only a few can be drilled at present.

SUMMARY OF THE INVENTION [0005] The present invention provides a keen need for a safe and efficient drilling operation on a concrete frame using a conventional rock drilling machine as described above. As a result of rapid development and research, and repeated trial-and-error and many trial productions and experiments over a long period of time, this time, as described later, finally, it is possible to accurately and easily perform drilling on inclined concrete slopes. Drilling machine for concrete slope reinforcement anchor with a new structure capable of
And a new method of perforating a concrete slope reinforcement anchor using the same has been successfully completed and put into practical use. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

Configuration of the Invention

As will be clearly understood from the embodiments shown in the drawings, which are representative of the present invention, the drilling machine for a concrete surface reinforcement anchor included in the present invention basically has the following configuration. I have. That is, an upright seat frame incorporating a reference frame portion for auger advance / retreat position indexing is integrally attached to the tip of the linear guide frame, and a punching mechanism portion is incorporated so as to be able to advance and retreat, and a moving wheel is provided on the rear surface. And a punching device main body, which is separate from the punching device main body and provided with a positioning mechanism for fixing to a predetermined position on a concrete surface and a fixing means, is prepared. After placing the drilling device seat on the upper surface of the predetermined place of the concrete method frame to be fixed, and after fixing, the drilling device main body is moved,
For a concrete slope reinforcement anchor that is guided and combined so as to be able to stand upright and fall down so that the perforation device seat serves as a pivot point of rotation and to fix the perforation device body in a vertical posture on a predetermined drilling position inclined surface. It is a drilling machine.

More specifically, the drilling machine for concrete slope reinforcement anchors according to the present invention having the above-mentioned basic structure has a drilling mechanism portion incorporated therein so as to be able to advance and retreat, and a moving wheel disposed on the back surface. At the end of the guide frame, an upright seat frame incorporating a reference frame for indexing the auger advance / retreat position is integrally attached to form a punching device body, while a main frame portion that can be placed on the upper surface of the concrete method frame The connection position regulating frame for guiding and fitting the reference frame of the perforating device main body upright seat frame is integrally incorporated around the inner center thereof, and the inside of the connection position regulating frame is An auger advancing / retracting position determined by the drilling device main body reference frame guided to the connection position regulating frame and formed in a connected state is provided with a collimation ring for drilling positioning. Before and after the main frame, S course downward at a Konrito method frame width above interval, the relative shape of the clipping projecting a pair of fixation arm incorporating a mechanism, by which shall be formed,
The punching device body is separate from the punching device seat, and the punching device seat is placed on the upper surface of a predetermined place of the concrete method frame to be punched, and after fixing, the punching device main body is moved and guided,
For a concrete slope reinforcement anchor having a configuration in which the upright and the overturning operation using the perforator seat body as a rotation fulcrum are freely combined, and the perforator main body can be fixed in a vertical posture on a predetermined drilling position inclined surface. It can be a punch.

The drilling device main body is fixed to the drilling device seat, which is formed separately, in an upright position. The drilling mechanism is moved up and down, and the auger is rotated and pressed toward the concrete method frame. It is configured to be separable from the drilling device seat. The main body of the drilling device is suspended by a crane or the like, or it is pulled by a wire rope, chain, or
It is desirable that an annular portion for connecting a rod or the like be formed.

The guide frame has a function of linearly moving the drilling mechanism forward and backward. The guide frame is usually made of a single frame steel, particularly an H-shaped steel, in a literal cross-sectional arrangement, and is formed by flange pieces. The endless chain belt and the perforating mechanism attached to and retracted from the upper and lower grooves are formed in such a structure as to be guided so as to reduce the weight as much as possible. It is also possible to form a combination of more than that, or to have a structure such as a lattice beam. Therefore, the cross-sectional shape of the member to be adopted is not limited to the H-shaped steel, for example, square steel, L-shaped steel, and the like. It is also possible to use a structure that can obtain a desired rigidity such as a shape steel, and furthermore, it is possible to further stabilize the structure by appropriately providing a guide such as a concave groove or a ridge for guiding a rock drilling drive source. And feasible guide for guiding the frame of the hole mechanism.

The auger is sufficient if it is incorporated in the drilling mechanism and performs a function of linearly drilling the concrete. The auger is a cylindrical body having a crushing bit at its tip. Later, another anchor member may be driven into the perforation, or it may have a bit at the tip and be formed in a tubular shape. After perforation, it may be removed from the perforation mechanism and used as a pile in its buried state. Also, after drilling, cement is pressed into the ground from the tip through the auger after drilling, and all the augers are integrated into the concrete frame, then removed from the drilling mechanism and left as it is It may be embedded as a driving pile.

The perforating mechanism has a function of moving the auger with a strength capable of excavating concrete along the guide frame and rotating the auger, and having a structure capable of attaching and detaching the auger. An electric motor or hydraulic motor for auger rotation drive fixed to the base that slides along the guide rail, or rotated by compressed air attached to a similar slide base. It may have a driven auger rotation drive source, and if necessary, a reduction mechanism or the like is incorporated in a drive source using electricity, hydraulic pressure, pneumatic pressure, etc., and the rotation speed of the auger is controlled by an operator's operation. It is also possible to freely change the structure so as to ensure a suitable drilling workability. Further, if necessary, it is possible to use not only the rotary drive but also known appropriate means that can advantageously perform excavation, such as a mechanism for applying fine reciprocation to the auger.

[0012] Further, the punching mechanism section also includes an advance / retreat drive mechanism that moves forward / backward along the guide frame.
A gear that meshes with a rack attached along the guide frame is coaxially connected to a rotation shaft of a drive motor fixed on a base that moves along the guide frame. Accordingly, the base can be configured to move forward and backward while being guided by the guide frame.In addition, as shown in the embodiments described later, an endless chain belt is interposed between the sprockets that are pivotally supported at both ends of the guide frame. By winding and driving the chain belt forward and backward by a drive motor or the like, it is possible to move the slide base connected to a part of the chain.

The moving wheels have a function of easily moving the punching device body in a posture of being rolled over, and may be provided at least at the front and rear of the guide frame or, if necessary, at a plurality of positions other than the front and rear. In addition to being able to change the direction and height of the wheels, it is possible to increase the operability of movement, and by adopting a soft material such as synthetic resin or rubber on the rolling surface, concrete It may be configured to protect the surface and the floor of the vehicle bed during transportation, suppress vibration during movement and transportation, and reduce noise generation.

The upright seat frame has a perforating device body standing upright on a perforating device seat, and is restricted to a perforating device seat described later.
By being guided, the reference frame portion (a frame material serving as a reference for determining the auger position) can be automatically placed and fixed at a predetermined position on the drilling device seat, and the punching device body is indirectly drilled. It has a function of integrating with the device seat body, and therefore has at least a reference frame portion necessary for determining the advancing / retracting position of the auger, and a member that is convenient for mounting and fixing to the punching device seat body, The punching device is formed so as to correspond to the predetermined member of the seat body. The structure in which the upright seat frame is connected and integrated orthogonally to the tip of the guide frame not only reinforces and connects only at the intersections of both, but also enhances the integration of both orthogonal shapes. for,
As typified by an embodiment to be described later, a reinforcing frame structure such that a truss structure is configured as a whole, for example, a reinforcing beam portion is inserted between a free end side of an upright seat frame and a rear end side of a guide frame. Is preferably formed so as to increase the rigidity of the drilling device main body and to suppress vibration and displacement during drilling work.

Further, in the upright seat frame, a part of the reference frame portion is engaged with a rotation fulcrum regulating portion of the punching device seat described later, so that the punching device main body holds the punching device seat. In addition to the structure, the fulcrum can be easily rotated from the rolled state to the upright state and from the upright state to the rolled state, and the posture can be changed at any time (that is, in the drilling stage and the separation stage). As shown in the figure, fixed rods are protruded and formed on the left and right sides of the reference frame portion, and the fixed rods are engaged with the rotation fulcrum restricting portion of the drilling device seat so that the drilling device main body is formed. It is also possible to adopt a structure in which the posture can be changed at any time with the seat as a fulcrum.

The drilling device seat body has a function of correctly regulating and guiding the reference frame portion of the upright seat frame at the concrete method frame drilling position, and has a function of allowing the guided position to be a correct drilling position. Function to adjust the position of the drilling position to the drilling position, and firmly fixed to the concrete frame linear part or intersection at the determined position, supporting the drilling device body in a vertical position with respect to the concrete method frame, and drilling The main frame part must have sufficient strength to support and fix the drilling device main body, and it has an annular shape like a concrete method frame. It is configured in a frame shape that can be placed flat, and the above-described upright seat frame is regulated and guided to determine its position, so that the position of the upright seat frame can be changed with the same location as a rotation fulcrum, For example, Like a connection position regulating frame as employed in the example, a Y-shaped groove forming plate or projection in a plan view for guiding the reference frame of the upright seat frame to a correct position, or a grooved steel. Or a notch or a gutter piece which also serves as a rotation fulcrum regulating portion having an arc cross section, and further, a positioning mechanism for adjusting a fixing position to the concrete frame, for example, a collimation. Rings and collimating bars (alternately, projecting horizontally from three or four sides toward the center, with the tip of each bar reaching the periphery of the ring), other mechanical equipment and devices effective for alignment, For example, a known centering mechanism or the like may be formed, such as one centered by the amount of protrusion of a holding bolt that also serves as a position adjustment described later.

The positioning mechanism including a collimating ring and the like has an important function for accurately determining a fixing position of the drilling device seat body to the concrete frame, and is provided on the concrete frame. The drilling position itself is fixed to the concrete frame by aligning the collimating ring and the like with the drilling position that is clarified by displaying etc., and thereafter, the positioning mechanism of the drilling device seat is adjusted. When the reference frame portion of the upright seat frame of the punching device main body is regulated, guided, connected and fixed, the state where the auger of the punching device main body naturally matches the drilling position can be realized. In addition, this collimating ring or the like has a shape such as a circle or a square that makes it easy to determine the center position,
After deciding the position and fixing the drilling device seat to the predetermined place in the concrete method frame, it remains in the drilling device seat as it is, and the auger of the drilling device main body advances in the collimation ring, described later. In addition to having the structure as in the embodiment described above, it exerts the function of positioning, and after the fixing of the drilling device seat body to the predetermined place in the concrete method frame, it is turned up and down or left and right, turned, or expanded and contracted. For example, it is also possible to adopt a structure that does not hinder the auger advancing / retracting operation.

Further, the perforating device seat body is provided below the main frame portion with appropriate fixing means to the concrete frame, for example, as shown in the embodiment described later, at an appropriate interval (concrete frame fixing). A structure that consists of a pair of fixing arms that extend downward in pairs and a pinch mechanism that is provided at the tip of the pair, with a gap that can accommodate the difference in the width of the parts to some extent. It is formed in a structure that presents a saddle shape or a table shape.
It is possible to use a position adjustment / holding bolt which is screwed to the opposite ends of the opposed fixing arms so that the distal ends thereof are opposed to each other, or other appropriate means.

With respect to the drilling device seat fixed in the correct position in this way, the drilling device main body is guided and rotated with the reference frame portion of the upright seat frame being regulated, and after being assembled vertically, the both of the two are aligned. By connecting the members facing each other with a clamp or other fixing metal, the drilling device main body is substantially fixed to the concrete method frame via the drilling device seat body accurately fixed at a predetermined position in the concrete method frame. Realizing a state accurately fixed to a predetermined location, the auger of the punching device body will also automatically face the predetermined punching position,
Drilling work by the drilling device main body becomes possible.

[0020]

[Related invention 1] In relation to the above-described drilling machine for concrete slope reinforcement anchors, the present invention also includes a method of drilling a concrete slope reinforcement anchor using the same. Basically, it is as follows. That is, the drilling position is marked at a predetermined drilling location on the upper surface of the concrete method frame, and the mark is fine-adjusted and positioned so that the collimation ring of the drilling device seat is captured.
After firmly fixing the concrete method frame at the drilling position using the same fixing means, move the drilling device main body while the guide frame remains in the overturned posture almost parallel to the concrete method frame upper surface, and The upright seat frame attached orthogonally is guided to the connection position regulating frame portion of the perforation device seat, raised to a position where it is stopped, and the rear end side of the perforation device main body is set at that position as a rotation fulcrum. After raising the guide frame so that the guide frame has a substantially vertical posture on the upper surface of the concrete method frame, the guide frame is substantially firmly fixed to the concrete method frame, and the drilling mechanism auger is automatically moved to an accurate drilling position. After that, the drilling mechanism is activated, the drilling is performed at a predetermined position in the concrete frame to a predetermined depth, and after the drilling operation is completed, the drilling device main body upright seat is formed. After releasing the connection and fixation of the boring device and the boring device seat, the rear end side of the boring device main body is now tilted about the pivot point so that the guide frame is substantially parallel to the upper surface of the concrete method frame. When the drilling device body is moved down to separate from the drilling device seat and the work is completed, or when drilling at multiple locations, the drilling device seat is fixed to the concrete method frame drilling position thereafter. The drilling machine for concrete slope reinforcement anchors, which repeats the operation and the drilling device main body connection to the fixed drilling device seat body, the fixing work, the drilling operation, and the detaching operation of the drilling device body from the drilling device seat body sequentially. This is a drilling method for drilling a concrete slope reinforcement anchor used.

The above-described drilling machine for a concrete slope reinforcement anchor according to the present invention is different from the drilling machine main body in which an upright seat frame is previously connected to a site where the concrete slope reinforcement anchor needs to be embedded and fixed. The body of the drilling device or the body of the drilling device in which the upright seat frame is also separated, and a separate, separate punching device seat consisting of the body of the drilling device, and a combination of independent tools, Loading and transporting other accessories such as compressors or drive motors, hoses and cords, winches, pulleys, wires and other materials and equipment required for drilling work,
While being carried in, the attached devices are arranged as prescribed,
If the upright seat frame is carried in a separated state, it is assembled and integrated as specified on the tip side of the punching device main body,
The drilling method according to the present invention is sequentially performed after the body of the drilling device is moved and arranged below the vertical skeleton to be drilled on the concrete slope constructed in a lattice shape.

In the drilling method of the present invention, it is a major component that the drilling method is basically handled separately except when the drilling operation is performed. That is, the drilling device seat is compact and lightweight enough to be easily carried by two workers, and the installation work of the drilling device seat is performed by setting the drilling position of the drilling device body described later by the auger. At the same time, it is indispensable to make an automatic decision,
It is a very important work to ensure the reaction force of the drilling device main body required at the time of drilling work, first, prior to the installation of the drilling device seat, as a first work process,
Marks were sequentially added to the positions at which the workers should drill, generally at the center of the intersection of the lattice structure, using chalk, etc., and the two workers marked the lowest position of the drilling device seat. The punching device seat is moved left and right and up and down so that this mark is captured by a positioning mechanism such as a collimating ring, and fine adjustment of the installation position is performed. At the same time as the positioning, an operation of firmly fixing the concrete method frame at the drilling position by using the fixing means incorporated in the drilling device seat must first be performed.

The positioning operation in this step may use any configuration as long as it can accurately and securely fix and support the drilling device body at a desired position, such as a collimation ring. For example, it can be pulled and fixed in a balanced state by a wire rope wound around a pulling device such as a plurality of winches, which is appropriately attached and fixed to a surrounding concrete frame, and provided on the perforating device seat body. A pair of left and right fixed arms are attached to the concrete frame in a saddle-shape manner, and the clamping mechanism is operated to move the main frame back and forth, back and forth, and fine-tune and position while achieving strong fixing. In addition, it is also possible to perform the alignment.

Waiting for the fixing of the drilling device seat, as a second operation step, the drilling device main body which has been previously standby beneath the vertical frame portion is moved so that its guide frame is substantially parallel to the upper surface of the concrete method frame. The connecting position of the perforation device seat body, which has been moved upward while remaining in the rolled position and the upright seat frame attached orthogonally to the tip of the guide frame is already fixed at the correct position. It is guided to the regulation frame and raised to the position where it is stopped. In this moving work, the vertical concrete method frame plays the role of a track, and the lifting wire that has been turned back via a pulley arranged in the upper part of the concrete method frame is driven up by a winch on the ground,
It is carried out by pushing up with human power, etc., but it is extremely convenient to adopt a drilling device main body with moving wheels mounted on the back of the guide frame in a well-balanced manner so that these series of operations can be performed smoothly. .

The boring device main body is moved upward, and the upright seat frame of the guide frame is guided by the reference frame portion being received by the connection position regulating frame portion of the boring device seat body.
When it has finished ascending to a position where it can be finally stopped,
The boring device main body is pivoted upward at that position to raise the rear end side of the boring device main body, the upright seat frame is placed on the boring device seat body, and the space between both opposing members is appropriately adjusted. In the third operation step of fixing by the means, at the same time as the operation of setting the guide frame to be in a substantially vertical posture on the upper surface of the concrete frame, the auger position of the drilling device main body is fixed to the predetermined drilling position. The work of automatically adjusting to the drilling position is also completed due to the device seat. Thus, a state in which the guide frame is substantially firmly fixed to the concrete frame is realized. The fixing of the drilling device main body to the drilling device seat body is performed by connecting and fixing with a strength enough to suppress vibration generated during the drilling operation and a detachment force generated between the drilling device seat body and the drilling device main body. In addition to connecting the drilling device body upright seat frame and the drilling device seat body with clamps or other metal fittings, the drilling device body is pulled by a plurality of wire ropes, metal rods, chains, or the like, and the connected state is established. It is also possible to keep it.

Thereafter, the drilling mechanism is activated to perform a drilling operation in a fourth operation step for drilling a predetermined position in the concrete frame to a predetermined depth. In this drilling work, a crushing liquid such as water, muddy water and / or compressed air, which stabilizes the crushing piercing at the tip of the auger, is provided by a pump provided separately.
Crushing liquid and / or air supplied by a compressor and / or air can be supplied to assist drilling work. When drilling on soft rock, water is added to the tip of the auger and hard rock is added. In the case of, good rock drilling can be performed by supplying compressed air, and the operator selects either water or air in consideration of rock drilling conditions and pumps, or An automatic control system may be provided to detect pressure applied to the auger or the like, and automatically select and execute supply of water or air.

Subsequent to the fourth operation step of the drilling operation, the connection and the fixed state of the perforating apparatus body upright seat frame and the perforating apparatus seat body are released in a procedure reverse to that of the third operation step, and then the rotating operation is performed. Fifth work step is carried out in which the rear end side of the drilling device main body is tilted around the fulcrum, the guide frame is returned to a substantially parallel posture on the upper surface of the concrete frame, and the drilling device main body is slightly moved downward to separate from the drilling device seat. Then, the boring work in the same place is completed.

Thereafter, when a plurality of holes are continuously drilled, the above-described first to fifth working steps are sequentially and repeatedly performed at appropriate drilling positions. Hereinafter, a detailed description will be given of several embodiments shown in the drawings, and a drilling method for a concrete slope reinforcement anchor and a drilling method for a concrete slope reinforcement anchor using the same according to the present invention. Will be able to be grasped more specifically and clearly.
