Pile driver for structural walls {Pile driver for structural walls}

The present invention relates to a pile driver for underground continuous wall construction that can obtain construction equipment at low cost. More specifically, in addition to the existing pile driver structure in which an auger driver and a chain drilling device for horizontal drilling are installed, a chain drilling device is provided. By installing an additional guide rail unit and a catch unit to hold the chain digging device, the vertical continuous wall and the horizontal excavation excavate the continuous continuous wall, while supplying the compressed air. And cement mortar to effectively build a concrete continuous wall in the ground, so that chain excavation work can be performed smoothly, and the excavation chain installed in the guide rail device consists of an outer unit and an inner unit. By joining joints with The present invention relates to a pile driver for underground continuous wall construction that prevents construction from being damaged due to equipment damage while maintaining the life of the excavation chain while preventing the rod from falling off.

Generally, in order to construct a continuous wall in the ground, a chain excavation device is installed to continuously form a cutting rake in a crawler vehicle or a mobile trolley to excavate a continuous wall (retaining wall) in the ground, and the excavated soil is removed by a dirt conveyor. The construction equipment for building underground concrete continuous walls was separately manufactured and used, so the economic burden on construction equipment was high.

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

And, in order to build the anti-soil barrier that is built around the building, first drill the H beam in the ground at regular intervals, then excavate between the H beams and install a block for preventing the earth and earth collapse to prevent the soil from flowing down. In recent years, a device and a method for constructing a continuous concrete retaining wall in the ground are used commercially.

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

An example of such an excavation device for constructing a continuous concrete retaining wall, which relates to an improved excavation device for constructing an underground retaining wall, includes: an endless track base assembly supported on a track track capable of moving along a direction parallel to the excavation line; A conveying assembly comprising a platform supported on the crawler base assembly and having a guide rail extending in a longitudinal direction thereof in a direction parallel to an excavation line, an adjusting chamber for moving on a rail of the conveying assembly; A mounting sleeve assembly supported on the side of the control chamber, an excavating arm pivotally connected to the control chamber for movement between the lowered and elevated movement positions through the mounting sleeve assembly, and by the excavating arm. Including a soil conveyor for transporting the excavated soil and attaching it to the side of the mounting sleeve assembly. An improved excavation device and method for constructing a built-in underground retaining wall (Patent Publication No. 10-1988-0000655, hereinafter referred to as 'prior art 1') has been disclosed.

In the prior art 1, the excavation tooth installed in the excavation Jane is configured by installing a rail on a separately manufactured track track, installing a sleeve assembly on the rail, and installing a track track having an excavation arm in the sleeve assembly. It is an improvement for the construction of underground retaining wall configured to be excavated, and this excavation device should manufacture a track track having a separate track chain excavator, and the track track includes auger drills and hammer bits. There is an economic problem in that the excavation construction costs are high, such as the use of a separate pile driver with an auger drill when attaching the center pile hole that supports the underground wall during excavation construction because it is not commercially available.

In particular, the prior art 1 can not proceed with the excavation operation that can insert the caterpillar chain to the depth of the deep track chain before excavating the deep underground underground excavation wall, deep excavation with a crawler excavator It took a lot of time to prepare for this, and there was an economic problem that required time and cost to excavate underground walls.

On the other hand, as another excavating device for forming a continuous wall of the roof, a mobile trolley moving on the ground to be formed as a continuous wall in the ground, and an upper frame configured on the mobile trolley, variable in length and extending vertically, the top of the mobile trolley A vertically movable guide pillar provided on one side of the frame, a chain sprocket rotatably provided on the guide pillar at upper and lower ends of the guide pillar, a chain sprocket rotatably provided at one end of the chain sprocket at an upper end of the guide pillar, and Underground including an endless chain having a plurality of excavator bukits at appropriate intervals along the endless chain to extend around the chain sprocket to be driven by the rotation of one or more chain sprockets and to form an endless chain bucketed cutter. Excavator for continuous wall formation Patent Publication No. 10-1993-0002619, hereinafter referred to as "prior art 2").

Excavation device of the endless chain type to the mobile trolley installed on the two rails described in the prior art 2 is only known in the art, it is necessary to continuously install a rail on the ground to which the mobile trolley can be moved. In addition to this inconvenience, the continuous continuous wall excavation work is inefficient, high cost, and takes a long time by the rails to the ground one by one.

In particular, even in the prior art 2 there is a problem that can not excavate the excavation hole that can insert the endless track chain to the depth of the deep track chain before excavating the deep underground drilling wall.

Excavator for constructing another underground continuous wall includes a buoy extending from the ground traveling vehicle and having one end protruding outward from one side of the traveling vehicle, and an extensible fixed detachably fixed to the one end of the buoy. A guide post, a chain drive wheel provided at the top of the guide post and an endless chain extending around the chain sprocket at the bottom of the guide post, a plurality of cutters alternately arranged on the endless chain to form an endless chain cutter. Excavation device for constructing a continuous underground wall, characterized in that the bit is provided with a plurality of stirring bars, and a guide post can be connected to the fluid source, the nozzle consists of a plurality of nozzles branching (Public Patent Publication No. 10-1993 -0021890, hereinafter referred to as 'prior art 3').

However, even in the above prior art 3, an endless chain that forms an endless chain cutter in an endless track vehicle is installed in the endless track vehicle to excavate a continuous wall in the underground, but the endless track alone is insufficient to form a deep excavation wall in the ground. There is a problem in that the excavation hole for inserting the caterpillar chain into the caterpillar chain can be inserted into the caterpillar chain.

Therefore, it takes a lot of time to excavate deeply with a crawler excavator, and it is inevitable to have economic problems that require time and cost to excavate underground walls.

Further, an underground continuous wall excavating apparatus, comprising: at least one sprocket movable on a rail and engaged with a rack installed on one of the rails, a moving trolley having sprocket driving means for driving the sprocket, and a frame disposed on the moving trolley; And an upper frame having an inclined frame that can be inclined with respect to the frame about a lower portion thereof, a saddle which is installed on an inclined frame so as to be slidable in a direction substantially perpendicular to the edge and has a chain driving wheel, Extendable guiding posts which are movable up and down relative to the inclined frame and rotatably connected at the lower end of the chain sprocket, endless chains extending around the chain drive wheels on the chain sprockets and saddles, alternately on the endless chains Cutter ratios arranged to form an endless chain cutter And digging a hole of a predetermined depth with a drilling device in the ground continuous wall, characterized in that it consists of a plurality of stirring bars, and a chain driving means for driving the endless chain, and the endless chain cutter of the excavator. Inserting into the hole, and excavating the ground in a predetermined direction by an endless chain cutter during the formation of the cement wall in the excavation hole, the underground continuous using the excavator according to claim 1 The wall method (Publication Patent Publication No. 10-1993-0021891, hereinafter referred to as "prior art 4") is disclosed.

However, in this method, the step of digging holes of a predetermined depth in the ground with a drill device is technically excavated with an auger drill before the process of digging a hole with an auger drill into which an excavator, which is an endless track, is inserted. Well known from the process of digging the ball, the caterpillar chain digging device is not only known by several prior arts but also can be adjusted to vary the cutting depth of the digging arm extending the digging arm and the digging arm is It is already well known by the technology that it has an excavation arm, each supporting a pair of upper and lower sprockets, and a segmented excavation chain is extended to the sprocket. Therefore, in the prior art 4 to drill the excavation hole to insert the endless track drilling device will have to be seen as a perforation hole with a separate drilling device because there is no auger drill device.

Previously, the chain type excavation device and construction methods for underground wall construction are to excavate the ground wall while constructing the rail on the mobile trolley and move the chain excavation device, or to excavate the ground wall while laying the rail on the ground and advancing the moving roll. There is a problem in that workability to continuously carry railing work on the ground, and the progress of the work fall, and also before the ground excavation with the tracked chain digging device before the first excavation of the ground wall When drilling the excavation hole for inserting the chain excavation device into the hole, excavate the excavation hole for inserting the chain excavation device with a pile driver equipped with a separate auger drill device according to the above construction method, and then install the underground wall chain excavation device. In addition to the underground wall excavation equipment, this requires a pile driver to drill a separate vertical excavation hole. Heavy wall excavation construction is delayed, and the excavation cost is increased due to the mobilization of equipment. Also, in the case of the endless track equipped with the endless track chain excavation equipment or the endless track with the excavating equipment, the excavation of the chain excavation equipment According to the resistance by depth, the endless tracks and the endless tracks cannot support the relative force of the excavating equipment, and thus, conversion excavation in any direction is impossible.

Excavation equipment is required to excavate the continuous continuous retaining wall, which is a problem exhibited above, and at the same time to be equipped with auger drill equipment, so that the drilling equipment can be inserted into the excavation depth, and equipment that is cheaply constructed for excavation cost is required and inexpensively. The equipment to be constructed is required.

In addition, the forward and backward reciprocating movement distance of the chain excavation device 400 is to extend the width of the guide rail device 200 and the stroke distance of the hydraulic cylinder 290 constituting a multi-stage to extend the forward and backward reciprocating movement distance. In addition, the multi-stage hydraulic cylinder 290 can be carried out using the multi-stage hydraulic cylinder 290, which is longer.

As described above, when the chain excavation device 400 is installed in the induction rail device 200 to excavate the ground with the chain excavation device 400, the reflection effect on the lead 110 of the pile driver 100 is derived. As the device 200 absorbs and eliminates an excessive force applied to the file driver 100 and the lid 110, the file driver 100 and the lid 110 may be prevented from falling down.

Thus, a 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 alternately installed on the rear surface of the transverse carrier 300, Like the lateral moving body 300, the lateral moving body 300 and the chain rig 400 showing the operation of moving the chain excavation device 400 to the right and moving to the left in a solid line are right. On the contrary, when reaching the end, the upper and lower multistage hydraulic cylinders 290 are extended, and at the same time, the upper and lower multistage hydraulic cylinders 290 are contracted and the transverse moving body 300 and the chain excavator 400 which are represented by virtual lines are contracted. By the reciprocating movement to move backward in the left direction, such as the lateral movement unit 300 and the chain excavation device 400 is continuously moved repeatedly, the lateral movement unit 300 and the chain excavation device 400 ) Gradually moving back and forth It is also possible to use a stroke distance of the multi-stage oil pressure cylinder 290 to the maximum.

15 is an exploded perspective view of the caterpillar excavation chain of the chain drilling device according to an embodiment of the present invention, Figure 16 is a plan view of Figure 15, the excavating chain 460 constituting the caterpillar are An outer unit 461 and an inner unit 462 that are alternately arranged and coupled by a rotation shaft 463, and the outer unit 461 includes at least one of which cuts the ground layers during excavation. The coupling part 464 which has the blade 464a is comprised.

In this case, the blade 464a is arranged laterally in the coupling portion 464, which can be selectively arranged according to the strength of the excavation layer, the number of the arrangement is determined within the range of 1 to 5 Will be.

At this time, when the excavation chain 460 is driven to shave the ground layers, the ground layers are sequentially shaved, so that the excavation chain 460 can be excavated with the smallest force to save power for driving the excavation chain 460. It was made.

On the other hand, the outer unit 461 includes a main body portion 461a and an extension portion 461b as a part of the caterpillar, which is relatively disposed on the outer side, and both ends of the main body portion 461a are connected to the rotation shaft 463. The expansion portion 461b is coupled to both sides of the main body portion 461a. In this embodiment, the expansion portion 461b has a rectangular parallelepiped shape.

Here, the expansion portion 461b illustrated in FIG. 17A may be formed of a rectangular rectangular parallelepiped, and the expansion portion 461b illustrated in FIG. 17B may have a trapezoidal plane. It may be composed of a cuboid.

In addition, the inner unit 462 is a part of a crawler disposed relatively inward.

The rotating shaft 463 may be configured in the form of a pin, and hinge-bonds the outer unit 461 and the inner unit 462.

Here, although the outer unit 461 and the inner unit 462 illustrated in FIGS. 15 to 17 are illustrated as a combination of a rectangular parallelepiped plate, this is for convenience of illustration, and the outer unit 461 and The shape of the inner unit 462 can be changed as many as such changes are included in the technical spirit of the present invention.

On the other hand, the coupling portion 464 is coupled to the caterpillar excavation chain 460 in this embodiment is coupled in the form of surrounding the expansion portion 461b of the outer unit 461 and the bolt 460a and the nut ( By coupling to the outer unit (461) by the not shown) it is easy to replace when the blade 464a is damaged.

In this case, the coupling of the coupling part 464 and the extension part 461b will be described in more detail. As shown in FIGS. 15 and 16, a pair of adjacent parts of the extension part 461b adjacent to the main body part 461a is provided. It combines in the form of enveloping the surface, the two extensions 461b located in the outermost of the four extensions 461b disposed in the two outer unit 461 is wrapped and combined in the above-described form, this configuration This is because the coupling between the outer unit 461 and the coupling portion 464 is easy. Of course, if the situation in the basement has to withstand a large shear force coupling portion 464 may be combined in a form surrounding all four expansion portion (461b).

In other words, the coupling chain is dependent on the coupling force by the bolt and nut, and the bolt must support all the shear forces generated during the movement of the drilling chain in the ground. There was a problem of departure.

Accordingly, in the embodiment of the present invention, the outer unit 461 constituting the excavating chain 460 is to maintain a form in which the coupling portion 464 wraps, so that the effect of the shear resistance area is widened and the area is widened The pressure is reduced, and therefore, an effect capable of supporting a larger shear force can be expected to prevent the blade 464a from escaping from the excavation chain 460.

Here, the blade 464a may be embodied in various forms in addition to the illustrated form as the excavation chain 460 is excavated land while moving together in the ground as the excavation chain 460 is driven, such modifications are included in the technical spirit of the present invention Should be viewed as a variation.

Meanwhile, the excavation chain 460 is supported by the frame 420, and the frame 420 supports the outer unit 461 and the inner unit 462, and the coupling part 464 and configures these components. It also performs the function of fixing the.

At this time, as shown in Figure 18, the frame 420 may be provided with an inclination measuring unit 800, the inclination measuring unit 800 is excavated by the excavation chain 460, when the It is a configuration for measuring the vertical inclination of the excavation chain 460, more specifically the frame 420, the inclination measuring unit 800 may utilize a commercially available inclination sensor. For convenience of display, the sensor position is indicated as being installed outside the frame 420 supporting the excavation chain 460, but the sensor position is preferably installed at a portion (such as an inner surface of the frame) that does not contact the ground. Although only one is shown in the drawing, it is possible to increase the accuracy of the measurement by installing several sensors.

On the other hand, if the inclination measuring unit 800 is installed in the frame 420, it is possible to measure the inclination of the excavation chain 460, it is possible to excavate while correcting the inclination of the excavation chain 460. .

That is, when the excavation chain 460 is perpendicular to the ground, the excavation chain 460 can be excavated to the deepest depth, but since the largest area is in contact with the ground, the greatest stress acts on the frame 420. It is very important to determine the most efficient inclination in consideration of the depth to be excavated and the stress caused by the ground, and to allow the excavation means to carry out the excavation while maintaining the determined inclination, which can be more efficiently excavated by the inclination measuring unit 800. To do that.

In addition, as shown in FIG. 18, an aggregate input unit 900 for injecting aggregate into the ground 600 excavated by the chain excavation device 400 may further include the aggregate input unit. 900 is provided in the forward direction of the chain excavation device 400 when the chain excavation device 400 is moved by the moving unit 130, the moving unit 130 is a lattice-shaped steel Further comprising a support frame 301 is configured, the aggregate input unit 900 is to be coupled to the support frame 301.

Here, the hopper described above is a configuration that can be simply installed on the support frame 301 and the installation cost is also relatively low, so it can be configured very efficiently considering the economics of the device.

Therefore, when the soil is injected into the front of the chain drilling device 400 by the aggregate input unit (900) (scattering the soil to be sprayed on the bottom surface GL located in the forward direction of the chain drilling device 400) In the process of excavating the chain excavation device 400, the earth and sand injected are mixed with the excavated soil and the hardening material, thereby increasing the strength of the ground wall.

That is, when the hardener is used as concrete, it is difficult to add and the cost is increased compared to the cement mix. The aggregate input unit 900 allows the surrounding soil to be used as aggregate to reduce the cost of the underground wall. The effect of increasing the strength can be expected.
