AUGER COMPRISING DOUBLE DRILLING ROD AND DRILLING ROD EQUIPPED WITH SAME AUGER

The present invention refers to double perforated rod 321 and the augers with device is provided to a puncturing mounted, or in the topcoat less more specifically, such as ground bedrock in formation difficult to clause other work sheet pile formed at the both ends of sheet pile junction ear the insulator is electrically connected through the adjacent sheet pile said sheet file remain a virtual be set on installation of alternately about line to position the perforated double selectively punctured alternately ground with rod 321 and the augers mounted relates to device of the apertures.

Generally various a drop bolt when the building structure to take advantage of an undergrand space of excavating the ground. a certain amount of. When retaining wall, and a composite underground method of excavating the ground are supplied to the inside of the retaining wall, and a composite underground that is not significantly impair order for the height of inner when adding method employs.

For preventing disruption for drilling retaining wall, and a composite underground method using lagging at mokp'otype with public law , sheet file retaining wall, and a composite underground effect and order by clause other performed with clause other public law file be possible for a sheet to be, a high pressure injection perforations the ground thus- with public law main heat using deep cement mixing, bentonite, to underground oh knit of excavating the ground to allow air to rise in a stable solutions, and internal reinforcement structure and a rail network sample wall of malleable pitted continuous underground using a. representative methods.

Order for the height of inner type include injection method, a high pressure injection method, deep cement mixing and blow-in public law or file clause other sheet such as method.

The ground method said injection for the injection of an grout gap and a order, a high pressure injection said ground won: a process using energy for blowing high pressure cutting at the time of breaking a the ground is filling the, said sheet file clause other public law sheet pile for clause other (river board pile) and is ground by, said deep cement mixing: a process cement mixing ground toe won. aggregate about agitating.

Retaining wall, and a composite underground utilized space geometry method securely the ground is selected according to the drilling when flange is coupled to the first flange thin explicitly within the environment-site method orders of optimum state according to economy steel rod and method for selecting the order.

Wherein, for the height of inner order of excavating the ground when be used as for the height of inner retaining wall, and a composite underground effect and satisfy sheet pile clause other public law economy (river board pile) which is excellent in arc so as to allow, holes are formed to easily engage the supply of sheet pile, after construction of a drawing sheet pile, and is separated from the and reused, in domestic and foreign is used, easily manufacture, until the current.

General also clause other public law the sheet pile as shown in 1a, vibration hammer (14) using sheet pile (16) a method for clause other ground a frangible in is method which can be used. The, said sheet pile (16) also the as shown in 1b, provided about line provided an imaginary method of recall of foodstuff regardless of the position thereof are inserted in ground. Wherein, said sheet pile (16) junction returning home lever adjacent sheet pile is formed (16) together outputs a relay driving signal. on is kept.

Therefore, ground is to be rigid or gravel, less layer, bedrock clause other public law by a vibration hammer is method is difficult to applied.

Ground is to be rigid or gravel, less layer, bedrock sheet file for clause other using jet watermark improved method of wet liquid to flow down. Also: a process water jet as shown in 2a, sheet pile (26) to be reduced in size rear view of steel pipe (27) at the tip sheet pile the belt from being a high pressure injection nozzle (not shown) by attaching high pressure water for cutting the ground vibration hammer (24) is of water purifying system clause other to. Also by the spray nozzle as long as said high-pressure fuel injection as shown in 2b, sheet pile (26) and an inner wall surface of the, i.e. virtual installation of line to the opposing surfaces and said steel pipe (27) are provided on.

Therefore, the watermark jet: a process hard ground or gravel layer less but smoothly clause other work a high-pressure injection pressure limitations of bedrock or in the topcoat at multiple channels/levels constructing, in addition water clause other sheet pile plate is used are accompanied by developing subsidence of ground after. having a regular interval are marked on.

For the height of inner jet the watermark a native shaft in order to rotate the box a is so simple and easy to assemble the device is used in clause other public law. Native clause other method less layer a is so simple and easy to assemble, bedrock i.e. shore hole is buried a triangle by using rigid or ground a riprap the muscle mouth it will do to bedrock intestine to make ' safety device for use when, as shown in 3a also, circular casing (33) and by this the urging force of, said casing (33) internal piercing rod (34) and drilling hammer (35) is located where it is heated perforated rod (34) mounted on top of the augers (32) using it into the drilled rod (35) attached to the fore-end of excavator hammer (35) consists of a-up Image and an excavating for or rock less the after and by filling an sand or soil in drilled holes, said casing (33) for drawing out the sheet pile method is that facilitate clause other.

I.e., a native clause other public law 3b is so simple and easy to assemble is native such as a sand or soil of rock is so simple and easy to assemble after replacing, herein sheet pile (36) for by a rope. inserted by clause other.

However, native clause other public law 10m or more native ball depth a is so simple and easy to assemble or bedrock degree of vertical drilling machines that, during operation, ball native in the case of overlapping construction the aim than an axial thickness of the support to change of construction quality occurs.

Is used for a development on conventional surfaces of a techniques,
