Since the pile part 410 is inserted into the hollow formed in the support plate 420, the support plate 420 is movable along the longitudinal direction of the pile part 410. However, the separation from the pile part 410 by the stoppers 431 and 432 formed at both ends of the pile part 410 may be limited.
- FIG. 11 illustrates a pile construction apparatus 1000 according to an embodiment of the present invention, and illustrates a process of injecting a pile 400 having a support plate 420 illustrated in FIG. 10.
- the construction apparatus 100 for piles has a hollow 415 formed therein, and piles 400 and piles 400 that are infiltrated into the seabed are undersea.
- Excavation pump device 200 that can be inserted into the hollow 415 formed in the interior of the file 400 to be inserted into the excavation pump device 200, wherein the excavating pump device 200, described above with reference to FIGS. 300).
- the pile may be either a pile 100 having the large flange 120 shown in FIG. 2 or a pile 400 having the support plate 420 shown in FIG. 10, and other piles having various shapes. It may also include.
- the pile 400 including the support plate 420 is mounted on the sea bottom to be installed.
- the support plate 420 is located at the lower end of the pile portion 410 by its own weight, and maintains a contact with the stopper portion 432 protruding from the lower end of the pile portion 410.
- the excavation head 210 excavates the seabed ground, and the excavating head
- the lower end of the pile part 410 is introduced into the seabed ground disturbed by 210 by its own weight.
- the support plate 420 of the pile 400 is disposed on the sea bottom.
- the stopper part 431 formed at the upper end of the pile part 410 presses the support plate 420.
- the support plate 420 may be introduced into the seabed together with the pile part 410, and the support plate 420 may be completely inserted into the seabed as shown in FIG. 11C.
- the support plate 420 may be inserted into the subsea ground while maintaining the state coupled with the pile part 410 to increase the contact area with the surrounding ground of the entire pile 400. Accordingly, the bearing capacity of the pile 400 with respect to the pulling force applied to the pile 400 can be improved.
- FIG. 12 is a perspective view illustrating a construction device for a pile including a driving socket
- FIG. 13 is a cross-sectional view of the construction apparatus for a pile shown in FIG. 12.
- the force required to infiltrate the pile into the ground that is, the size of the tube input may be increased. More force may be required to infiltrate the pile, and the penetration of the pile may be facilitated by additionally implementing the driving process.
- the construction apparatus 1000 for piles includes a driving socket 500 mounted on an upper end of the pile 400 to allow additional penetration of the pile 400 by driving. ) May be further included, and in this case, an opening 510 through which the discharge pipe 220 of the excavating pump device 200 passes may be formed at a side of the driving socket 500.
- the pile construction apparatus 1000 may include the driving socket 500 to additionally perform the driving process together with the penetration process of the pile 400 by the excavation pump apparatus 200.
- the hitting machine 600 may indirectly apply the pipe input due to the hitting to the pile 400 by hitting the hitting socket 500.
- the driving socket 500 may be formed separately from the driving apparatus 600 and the pile 400, and may be integrally formed with the driving apparatus 600 or the pile 400.
- the opening 510 formed at the side of the driving socket 500 may provide a passage of various cables 260 as well as the discharge pipe 220, and is required for driving the excavation pump device 200 through the cable 260. It is possible to transmit and receive a signal for supplying power or controlling the excavator pump apparatus 200.
- opening hole 150 wire
- 252a and 252b fixed part 253a and 253b: excavator
- 254a, 254b exit 255a, 255b: inlet space
- support frame 262 base
- the construction cost is reduced by easily infiltrating the pile in a short time by discharging the liquefied seabed to the outside of the pile using a seawater pump by disturbing the hard sedimentary layer or the sandy bottom ground that obstructs pile penetration. There is an effect that can be saved.
