When the chain driver 210 is operated as described above, the excavating chain 260 of the caterpillar is rotated, and the rake cap 265 covered with the rake 261 is cut horizontally to cut the ground layer 300. Will be

As the rake cap 265 scrapes off the stratum, the rake cap 265 is worn out by friction, and the excavation ability is lowered, thereby replacing the worn rake cap 265. The rake cap 265 is a rake 261. Since it is fixed to the pin (266), remove the pin (266) fixing the rake cap (265) and remove the rake cap (265) and replace the new rake cap (265).

Thus, the worn rake cap 265 can be replaced in the field and continued excavation construction can solve the problem that the excavation construction is stopped due to the damage of the rake cap 265 to extend the air due to the interruption of the excavation work This also has the economic effect of preventing cost increases.

As described above, the excavation work is performed to form the horizontal continuous wall horizontally with the excavation chain 260 of the endless track, and the pneumatic supply pipe 212 installed in the chain excavation arm 230 of the excavation device 200 is performed. Pneumatic is supplied to blow the soil to be excavated by the chain digging device to crush the soil mass and the concrete mortar (330) is mixed with the excavated soil while the cement mortar is supplied to the ground through the cement mortar supply pipe (213) Underground concrete continuous retaining walls filling the horizontal excavation portion 320 is constructed.

As such, when the concrete mortar fills the horizontal excavation part 320, the H-beam 340 is driven before the concrete mortar is hardened to build the underground concrete continuous retaining wall.

The present invention is vertically excavated with a conventional auger drill mechanism on a crawler crane operating on the ground, and then horizontally excavated with a chain excavation device to install pneumatic and cement mortar to form underground continuous walls with cement concrete. It has the effect of constructing the wall, and by installing the chain digging device, it is possible to construct vertical concrete wall as well as vertical excavation with the roller crane, so it is economical effect to reduce the equipment cost and diversify the function. If the rake to excavate the soil in the chain digging device that can be excavated horizontally, it can be used only replace the worn rake, it is a useful design with high economical efficiency and workability.
