In addition to the vertical excavation of the auger driver, it is composed of a concrete malta pouring hole and pneumatic spraying hole, and a rake cap that covers 1-5 pieces of rakes for each of the caterpillar chain brackets constituting the above-mentioned chain drilling device. Ground track chain excavation device excavates underground continuous wall by horizontal excavation, placing cement mortar through beam By building the wall firmly and quickly, the construction capacity can be improved, the construction period can be shortened, it can contribute to the safety engineering works, and it is equipped with a set of clamping devices facing the induction rail device that can obtain low horizontal equipment. To provide a pile driver for underground continuous wall construction.

The present invention is to install a guide rail (inducement rail.-unit) and a chain digging device to catch the chain drilling device in the pile driver having a conventional hammer drill or auger driver Smooth chain digging and increase digging ability, and selectively configure 1-5 rakes in the chain bracket of the chain digging device installed in the above guide rail device, and install the rake cap to wrap the rakes By replacing only the rake cap worn out, it extends the service life of the chain bracket and prevents construction interruption due to equipment damage. It is characterized by a pile driver for constructing a continuous underground wall with an induction rail device and a clamping device. .

Generally, in order to build a continuous wall in the ground, a chain excavation device is formed to continuously form a cutting rake in an endless tracked vehicle or a moving wheel, and the continuous wall (retaining wall) is excavated in the ground and the excavated soil is removed with a dirt conveyor. As the basic construction equipment for building underground concrete continuous wall was manufactured and used separately, the economic burden on construction equipment was great.

In general, when constructing a high-rise or low-rise building is the foundation, the construction is progressed while the anti-soil barrier is installed to support the load caused by the earth pressure surrounding the building.

And, in order to build the anti-earthquake blocking wall that is built around the building, first hit the "H" beam in the ground at regular intervals, and then excavate between the "H" beams and prevent the earth and sand from falling down. ) To establish a barrier to prevent earth and sand collapse.

Recently, a device and method for constructing a concrete continuous retaining wall in the ground as the anti-soil blocking retaining wall disclosed at home and abroad are commercially available.

As a device for constructing the underground concrete continuous retaining wall as described above, the excavation chain driven by the hydraulic arm motor is installed, and the excavation chain is an endless track vehicle in which excavation arms are formed with cutting teeth. It is also known to build underground concrete continuous walls by pouring mortar into the excavated trench.

As an example of such an excavation device for constructing a continuous concrete retaining wall, the present invention relates to an improved excavation device for constructing an underground retaining wall. An endless track assembly supported on an endless track that is movable along a direction parallel to the excavation line, and a guide rail supported on the endless track assembly and extending longitudinally along a direction parallel to the line of excavation A conveying assembly including a platform having a groove, an adjusting chamber for moving on a rail of the conveying assembly, a mounting sleeve assembly supported on a side of the adjusting chamber, a lowered excavation posture and an elevated movement through the mounting sleeve assembly; A drilling arm connected in a pivotal manner to the control room for transport between the postures, and a soil conveyor transporting the soil excavated by the drilling arm and attached to the side of the mounting sleeve element. Improved excavation device and method for the construction of underground retaining wall (Publication Patent Publication No. 10-1988-0000655) (Publication 1988,03,28) In the present invention, this invention constitutes a rail on a separately manufactured track track, installs a sleeve assembly on an rail, and installs a track track including an excavation arm on the sleeve assembly so that the excavation tooth installed in the excavating agent is excavated. It is an improved excavation device for constructing the underground retaining wall. The excavation device should manufacture a track track equipped with a separate track chain excavation device and commercially use auger drills and harbor bits as its track tracks. When you install a center pile that supports the underground wall during construction, you will have to raise the cost of excavation, such as having to drill using a pile driver with auger drill.

In particular, here, there is a problem in that excavation excavation that can insert the caterpillar chain into the caterpillar chain to a deep depth before excavating the deep underground excavation wall is a problem.

Therefore, it takes much time to excavate deeply with the caterpillar excavation device, and there is an economic problem that requires time and cost to excavate underground walls.

Further, as another roof continuous wall forming excavation device, a mobile trolley wheel moving on the ground to be formed as a continuous wall in the ground, and an upper frame configured on the twirl wheel, variable in length and extending vertically A vertically movable guide pillar provided on one side of the upper frame of the rotary wheel, a chain sprocket provided rotatably on the guide pillar at upper and lower ends of the guide pillar, and one end of the chain sprocket at the upper end of the guide pillar. A plurality of excavator buckets at appropriate intervals along the endless chain to extend around the chain sprocket and to form an endless chain bucketed cutter so as to be driven by the rotation of one or more chain sprockets and the provided chain sprocket. For forming underground continuous walls including endless chains Although a cutting device (Patent Publication No. 10-1993-0002619) is disclosed, the excavating device of the endless chain type in the moving wheel rotary wheel installed on the two rails is merely a technique well known in the prior art. Not only is it inconvenient to lay the rails on the ground that are clear and the movable wheel can move, but also the continuous continuous wall excavation is inefficient, expensive, and takes a long time by covering the rails on the ground. I will be sitting down.

In particular, there is also a problem that the excavation hole that can insert the endless track chain to the deep end of the endless track chain before excavating the deep underground excavation wall is a problem that can not be excavated.

Excavators for constructing another underground continuous wall include a buoy extending from the ground traveling vehicle and having one end protruding outward from one side of the driving vehicle, and an extensible fixed detachably fixed to the one end of the buoy. A plurality of cutter bits arranged alternately on the chain to form a guide chain, an endless chain extending around a chain drive wheel provided at the top of the guide post and a chain sprocket at the bottom of the guide post. And a plurality of agitating bars, and guide posts, which can be connected to a fluid supply source, and an excavation device for constructing a continuous underground wall, characterized in that the nozzle consists of a plurality of nozzles for branching (Public Publication No. 10-1993-0021890). ) Is being launched, but here also infinite infinite chain to form an infinite chain cutter on a crawler vehicle It is considered that the continuous wall is excavated in the track vehicle by installation in the tracked vehicle, but it is considered to be insufficient to form the deep excavation wall in the underground only by the endless tracked vehicle. There is a problem that can not excavate the excavation hole that can be inserted into the track chain to the deep.

Therefore, it takes a lot of time to excavate deeply with a tracked excavator, and there is an economic problem that requires time and cost to excavate underground walls.

Further, an excavating device for underground continuous wall, comprising: at least one sprocket movable on a rail and having at least one sprocket engaged with a rack installed on one of the rails and a sprocket drive means for driving the sprocket; A frame disposed, an upper frame having an inclined frame which can be inclined with respect to the frame about a lower part, saddles which are installed on the inclined frame so as to be slidable in a direction substantially perpendicular to the ring and having a chain driving wheel; Extendable guide posts located below the chain drive wheels, movable up and down with respect to the inclined frame and rotatably connected with chain sprockets at the lower end, infinite chains extending around the chain drive wheels on the chain sprockets and saddles; Multiple cutters alternately placed on a chain to form an endless chain cutter Excavating device for underground continuous walls and digging a hole of a predetermined depth with a drill device in the ground, comprising a plurality of stirring bars, a chain stirring means for driving an infinite chain, and an infinite chain cutter of the excavating device. Using the excavating apparatus according to claim 1, comprising inserting a hole into the hole and excavating the ground in a predetermined direction by an endless chain cutter while forming a cement wall in the excavation hole. A continuous wall method (Publication Patent Publication No. 10-1993-0021891) is disclosed, in which the step of digging a hole of a predetermined depth with a drill device in the ground in the method of the present invention in view of the high creative surface of the requirements of the invention patent Excavation of the hole into which the caterpillar excavation device is inserted with an auger drill is a method of digging a drill hole with an auger drill before the file is hit. Since it is only a publicly known step, the novelty will be lost. Also, the caterpillar chain excavator is not only known by the prior art, but also to change the cutting depth of the excavating arm that extends the excavating arm. It can be said that the digging arm can be adjusted and is already known by the technology that it has an excavating arm frame supporting the upper and lower pairs of sprockets, and the fragmented excavating chain is extended to the sprocket.

In particular, the drilling of the excavation hole to insert the crawler, which is the track chain, should be regarded as the drilling of the hole with a separate drilling device without the auger drill in the invention.

Conventional chain-type drilling rigs and construction methods for forming underground walls as described above construct a rail in a moving wheel rotation wheel and excavate the ground wall while moving the chain rig, or drill the ground wall while laying the rail in the ground and advancing the moving roll. There is a problem of inconvenient worker and continuous progress of railing on the ground, and the progress of the work before the excavation of the ground wall. When forming the excavation hole to insert the excavation device, by excavating the excavation hole to insert the chain excavation device with a pile driver equipped with a separate auger drill device as a construction method, this is to insert the underground wall chain excavation device, In addition to the device of the invention, pile driver equipment for drilling a separate excavation hole is required. Excavation cost increases due to the mobilization of equipment, and in the case of infinite tracks equipped with endless track chain excavation equipment or endless tracks installed with excavation equipment, the resistance due to the excavation depth of chain excavation equipment According to this, the tracks of the endless tracks and the endless tracks cannot support the stationary force of the excavation equipment, and thus excavation in any direction is impossible, so the equipment for laying the rails on the ground and using the moving rolls to excavate the ground is started. There is a fact that was exhibited in Japan.

FIG. 9 is an exemplary view of a chain excavator showing a forward and backward state of a chain excavator installed in an induction rail device according to the present invention, and FIG. 10 is a diagram illustrating a front and back of the chain excavator of FIG. 9. 3, the induction rail device 200 installed in the reader 110 of the pile driver 100 is composed of an assembly split body capable of assembling in three directions in the longitudinal direction, and the induction rail device 200. The horizontal rail 250 and the horizontal rail 260, which comprises the groove rails 251 and 261, respectively, constitutes a horizontal movable body 300 which reciprocates on its groove rails 251 and 261 laterally. Chain excavation device 300 is installed in the front of the reciprocating movement (forward and backward) like the transverse moving body 300 on the induction rail device 300.

In addition, the reciprocating motion (forward and backward) of the transverse moving body 300 is smooth and flexible by the plurality of rolls 320 respectively installed at the upper and lower ends of the horizontal moving body 300.

In particular, the transverse moving body 300 which moves laterally in the induction rail device 200 constituted by the assembly split body as described above opposes the left longitudinal beam 270 and the right longitudinal beam 280 of the induction rail device 200. Alternatively, the transverse moving body 300 and the chain excavator 400 are reciprocated between the multi-stage hydraulic cylinders by a plurality of multi-stage hydraulic cylinders 290, which are fixedly staggered. When the elongation) is extended, the upper and lower stage multi-stage hydraulic cylinders 290 installed at the opposite positions are contracted, and the transverse moving body 300 and the chain digging device 400 are moved to the right side and vice versa. When the transverse moving body 300 and the chain rig 400 which have indicated the operation in a solid line advance in the right direction and reach the end, on the contrary, the upper and lower multistage hydraulic cylinders 290 are extended and at the same time, the upper and lower multistage hydraulic cylinders 290 ) The chain excavation device 400 also continues like the transverse mover 300 by a reciprocating motion that contracts and moves backward in the left direction, such as the transverse mover 300 and the chain excavation device 400 indicated by the virtual line. By repeating the movement to the chain excavation device 400, such as the transverse moving body 300 was to continuously back and forth action.

At this time, when the transverse moving body 300 and the chain digging device 400 installed in the guide rail device 200 as described above is moved (forwarded) to the right axis as indicated by the solid line, the pile driver 100 The rail induction device 200 is slightly pulled up by the fleece and ropes installed on the top save at the top of the leader 110, and then the file is moved as far as the lateral moving body 300 and the chain excavator 400 move forward. Endless track chain is installed in the chain digging device 400 by advancing the driver 100 and again performing the operation of lowering the rail induction device 200 again to be seated (for example, similar to the advance operation of avalanche). It will be possible to excavate the underground continuous wall.

In addition, the reciprocating (forward and backward) travel distance of the chain rig 400 extends the width of the induction rail device 200 and the stroke length of the multistage hydraulic cylinder 290 to extend the reciprocating (forward and backward) travel distance. After that, it can also be adjusted by using a multi-stage hydraulic cylinder 290, the stroke length of the multi-stage hydraulic cylinder 290 is long.

It has been found by a number of experiments that one device 200 absorbs excessive force on the pile driver 100 and the lid 110 to prevent the pile driver 100 and the lid 110 from falling.

FIG. 11 is another exemplary view illustrating a reciprocating action of the chain excavation device installed in the induction rail device according to the present invention. As illustrated in FIG. 9, the transverse moving body 300 installed in the induction rail device 200 is illustrated. When the chain digging device 400 moves (forwards) to the right side as indicated by the solid line, the rail is guided by the fleece and ropes that are normally installed on the top save of the leader 110 of the pile driver 100. After pulling up the device 200 slightly, the lateral moving body 300 and the chain digging device 400 move forward (move) the pile driver 100 and then lower the rail induction device 200 again. By continuously performing the seating operation is to be able to excavate the underground continuous wall with the endless track chain installed in the chain excavation device 400.

Thus, the plurality of multi-stage hydraulic cylinders 290 fixed to the left longitudinal beam 270 and the right longitudinal beam 280 of the rail induction apparatus 200 are installed on the rear of the transverse moving body 300 to cross each other. Like the lateral moving body 300, the lateral moving body 300 and the chain rig 400 showing the operation of moving the chain drilling device 400 to the right and moving to the left in a solid line in the right direction.
