L) is connected and extended to the external control unit.

10 and 11 are diagrams of the construction procedure using the ground perforation guide device of the present invention, Figure 10 is a topography of the present invention for constructing the pile in the water or the seabed where the upper soft layer 42 is present on the lower rock layer 44 Figure 1 is an example of using the adaptive ground boring guide device, Figure 11 is an example of using the topographic condition adaptive ground drilling guide device of the present invention to construct a pile in the sea or the seabed where the rock layer 44 is present.

First, referring to FIG. 10, the construction procedure for simultaneously constructing piles at various locations in the water or under the sea where the upper soft layer 42 is present on the lower rock layer 44 using the adaptive terrain drilling guide device according to the present invention is described in more detail. Explain.

The contractor loads the small equipment such as the ground drilling guide device of the present invention on a barge, a small crane ship or a small self-elevated pants (Self Elevated Pontoon Barge) installed with a small crane and moves to the surface of the excavation position (Fig. 10). Step 1). At this time, the spacing between the guide structure 2 constituting the guide structure assembly 4 is adjusted in advance in accordance with the planned installation interval of the pile.

Thereafter, the guide structure assembly 4 of the ground boring guide device is placed in the medallion subsea excavation position by using a small crane or the like (second step in FIG. 10). The control unit 40 reports various necessary situations to the control unit from time to time while communicating with the control unit outside the communication unit 36 cylinder drive unit 34.

When the ground detection sensor 22 installed on the bottom of each guide structure 2 detects ground contact, the control unit 40 responds to the ground, and as shown in the third step of FIG. 10, the entire guide structure 2 is horizontal. It is controlled through the height adjustment cylinder drive 34 to maintain the state. That is, the controller 40 determines the current tilt state of all the guide structures 2 by using the detection signal of the horizontal sensor 20 and drives the height adjustment cylinder driver 34 so that the current tilt becomes a horizontal state. The extension length of the guide structures 2 through the height adjustment cylinder 14 is appropriately controlled.

When the entire guide structure 2 is kept horizontal by proper expansion and contraction adjustment of the guide structures 2 constituting the guide structure assembly 4, the vertical guide hole 9 of each guide structure 2 is in contact with the water surface. It is going to be vertical. In other words, a precise drilling perpendicular is formed. At this time, since the flange-shaped footrest 12 of each guide structure 2 forms a large floor area, the floor can be safely landed on the sea floor even if the floor is slightly soft or soft.

After the ground drilling guide apparatus of the present invention is settled in the subsea excavation position, if all of the plurality of guide structures 2 remain horizontal, the lifting tool of the small crane is released and is pulled up to the barge.

Thereafter, as in the fourth step of FIG. 10, the tubular casings 18 are suspended and inserted into the vertical guide holes 9 of the guide structures 2 held vertically, respectively, and each horizontal movable rotation wheel part 30. By activating), the horizontally advanced guide roll 26 is roll-supported to the tubular casing 18.

 Thereafter, as in the fifth step of FIG. 10, the upper soft layer 42 of the casing 18 is drilled by using the drilling tool 46 mounted on the lower end (tip) of the tubular casing 18. The guide roll 26 is driven using the guide roll driving part 24 to be inserted into the drilling hole 48 formed in the bottom thereof, or press the tubular casing 18 from the top.

By inserting a plurality of casings 18 in the same manner as described above, it is possible to simultaneously drill vertically to the rock line (step 4 of FIG. 10), and thus the hole 48 of the soft layer 42 is supported by the casing 18. Does not fall on

After that, the casing 18 descends to the surface of the rock layer 44 but no longer, and only the drilling tool 46 extends the drilling hole 48 while maintaining the verticality so as to simultaneously drill the desired point. (The fifth step of FIG. 10).

When the simultaneous drilling of several places is completed, each drilling tool 46 is recovered (sixth step of FIG. 10).

Thereafter, through the vertical guide hole 9 of the guide structure 2, through the casing 18 vertically installed to the upper soft layer 42 and through the hole 48 formed in the rock layer 44 under the casing 18. Simultaneously inserting several piles 50 such as steel pipes (seventh step of Figure 10),

Then, using the piles 50 formed at the same time, the construction of the foundation 52 is completed (the eighth step of FIG. 10), and after the construction of the foundation 52 is completed, additional installations on the required foundation ( 54) can be completed by the construction (step 9 of FIG. 10).

In the ninth step of FIG. 10, one example of the foundation 52 and the additional fixture 54 installed thereon is a pier where the foundation 52 is a pier substructure and the additional fixture 54 is a pier pillar and pier coping. (coping) and bridge upper structure.

Next, with reference to Figure 11 will be described the construction procedure for the simultaneous construction of the piles in the water or the seabed only the rock bed layer 44 is present using the terrain condition adaptive ground perforation guide device of the present invention.

In the pile construction procedure in which only the rock layer 44 of FIG. 11 exists, the casing 18 is inserted only to the surface layer of the rock layer 44, and the rest of the construction procedure is the same as the pile construction procedure of FIG. The insertion of the casing 18 to the surface layer of the rock layer 44 is to prevent the maintenance of the verticality of the drilling tool 46 due to the ground surface of the rock layer 44 being broken during the drilling.

In addition, the casing 18 inserted into the vertical guide hole 9 of the guide structure 2 may serve as a reaction wall of the self-propelled drilling tool 46. After the body of the self-propelled drilling tool 46 is in close contact with the casing 18, it will be able to perforate while advancing downward in that state. When the drilling hole 48 of the rock layer 44 is completely hard, the self-propelled drilling tool 46 is supported by the drilling hole 48 closely, and then moves downward in the state.

The horizontal adjustment of all the guide structures 2 in the case of the rock layer 44 on the ground surface is preferably performed by using the support legs 16, and the guide structures 2 when the support legs 16 are not enough. It is also preferable to use the height adjusting cylinder 14 together to perform horizontal maintenance.
