The present invention relates to a water exploration wall excavator for constructing a water expedient wall to reinforce the ground during underground excavation work, and more specifically, casing and excavation of the drilling device portion while installing the wall surface excavation unit in the form of "+" By allowing the spheres to rotate in opposite directions, it is to provide an exponential wall excavator that can be easily connected in all directions with adjacent exponential walls and can be constructed with a small power.

In general, when constructing various buildings as well as port construction or subway construction, the first thing to be done is underground excavation work. If you dig deep into the ground for underground excavation, the water is weak from the ground and the ground becomes weak. There is a big problem such as collapse and the collapse of the placenta by the weight of the adjacent building.

Therefore, in the case of underground excavation for the construction of various buildings, the basic construction to reinforce the ground must be carried out. In general, the most easily seen method is the underground construction when constructing subway construction or general buildings. How to install a block for preventing earth and earth collapse on the "H" beam so as to dig out the ground where the "H" beam hits the H beam at a predetermined interval, and to prevent the sediment from flowing out. As shown in FIG. 2, two methods are used to excavate an underground wall while underground drilling as an exponential wall excavator.

The index wall excavator 10 shown in FIG. 1 connects two index wall excavators 10 as the connecting members 20 to form the index wall 30 in the ground. Excavating holes (11) provided with a plurality of bits for rotation to form a cylindrical hole 31, the first hole (31) excavated in a cylindrical shape as a chain excavator (12) located above the excavator hole (11) On one side of the wall surface is to be formed long groove 32 is to be formed.

In the process of forming the hole 31 and the long groove 32 as described above is filled in the hole 31 and the long groove 32 while spraying the punched water mixed with the chemical liquid, mortar, and water to the lower side of the excavator 11 The perforated water solidifies to form the exponential wall 30 in the ground.

On the other hand, the ground wall excavator 10 can be used to hang on a crane (not shown) and can be ground excavated by the ground of the ground wall excavator (10).

As shown in FIG. 1, the two expansive wall excavators 10 are connected to each other as the connecting member 20, and each chain excavator 12 is installed inwardly so as to face each other, thereby making the long groove 32 as shown in FIG. This connection is made to form the exponential wall 30, and by using the exponential wall excavator is a combination of the two as described above to form a continuous wall as shown in FIG. have.

However, such a conventional exponential wall excavator has a problem that a large power is required because the perforated cylinder-shaped hole for forming the exponential wall as a single excavation is increased. In addition, since only one chain excavator is formed in one direction to form the long groove for wall formation, as shown in FIG. 2, it is difficult to connect the adjacent exponent walls. Since the inefficient work to form the wall (a) has to be done, there is a problem that the working time is delayed and the construction cost is increased due to the large amount of chemical liquid, mortar, water, etc. for forming the exponential wall.

Conventional exponential wall excavators are difficult to construct exponential walls despite the problems described above, and the exponential walls thus constructed have only weakly structural problems.

Therefore, the present invention is to completely solve all the problems as described above, the object of the present invention is to construct an exponential wall with a small power to the exponential wall excavator for constructing the exponential wall is constructed to reinforce the ground, By facilitating interconnection with adjacent exponential walls, the wall excavation device is installed in the form of a "+" to construct a solid exponential wall and provides a water wall excavator that the casing and the digging holes of the perforation device are rotated in opposite directions.

When the rotational force of the motor 110 is transmitted to the second gear 134, the second hollow shaft 105 installed in the second gear of the second gear 134 is half the same as the two gears of the second gear. It rotates in a clockwise direction and rotates counterclockwise with the sun gear 152 of the wall surface excavation device unit 150 provided in the second hollow shaft 105.

As the sun gear 152 is rotated in the counterclockwise direction as described above, each of the satellite gears 153 meshed with the sun gear 152 is rotated in the clockwise direction, and the satellite gears 153 are the same. A bevel gear 155 is installed on the shaft 154, and another bevel gear 156 for driving the sprocket 158 outside the casing 151 is meshed with the bevel gear 155 at a right angle to install the sprocket ( 158). At this time, the chain support 159 is installed fixed to the outer end of the casing 151, the sprocket 160 is installed on the front end, chain sprockets 158, 160 are arranged on a predetermined interval a plurality of bits 161 are arranged at a predetermined interval 162 is rolled to excavate the long groove of the "+" shape in all the holes excavated by the drilling unit 170.

As described above, the drilling device unit 170 and the wall excavation device unit are operated at the same time. As the drilling device unit is located below the wall excavation device unit, the drilling device unit first excavates and descends a cylindrical hole, and the upper side thereof. As the wall surface excavation device portion 170 is located in the excavated hole in the "+" shape is to excavate the long groove.

In the process of digging the exponential wall as described above, through the supply pipe 109 installed above the first hollow shaft 101 as shown in FIG. 3, perforated water mixed with chemical, mortar, and water is supplied to the perforated water. It is injected through the outlet hole 179 of the first excavation hole 175 shown in the excavation wall excavation is made more easily, the perforated water in the hole and the long grooves excavated by the excavation wall excavator 100 of the present invention It is filled and hardened to form an exponential wall. At this time, since the first hollow side 101 is being rotated but the supply pipe 109 is not to rotate, the first hollow shaft 101 is provided with a shovel 108 provided with a bearing 107 and the shovel 108 is provided with a tip. The supply pipe 109 is installed in the supply pipe 109 does not rotate to be able to stably supply the punched water. In addition, as shown in FIGS. 3 and 10, a suction pump 210 that is detachable as necessary is installed on the frame 104 of the water jet excavator 100 so as to drill the ground as the drilling unit 170.
