The trough support pile of the present invention has the following effects. 1. The trough support pile is rotated by the rotary driving body fitted to the fitting portion, and the trough support pile can be easily inserted into the ground, so that the labor burden of the operator is greatly reduced, and the workability and work efficiency are reduced. Efficiency is improved, the work of inserting the trough support piles is speedy, the number of personnel can be significantly reduced, and the cost can be significantly reduced. 2. The work can be done easily without having to dig a hole or back-fill it into a predetermined position at a predetermined depth, making it easy to insert even in places with steps. In addition, the height of the trough support pile (horizontal level) ) 3. There is no need to hit the head of the trough support pile at the time of insertion, so there is no damage such as chipping, cracking or cracking of the head. 4. Since the screw-shaped blade is provided on the outer periphery of the main body along the longitudinal direction, when the trough support pile is rotated by the rotary driving body, the blade also rotates, and the trough support pile is easily inserted into the ground. Since the blades cut into the ground, they are stable without using mortar or reinforcing material, and the inserted trough support pile is unlikely to rise from the ground or sink into the ground. For this reason, the horizontal level of the trough support is kept constant, the trough does not tilt or become uneven in the longitudinal direction, and the cables laid in the trough are less likely to be damaged. 5. When the rotary driving body is reversely rotated, the trough support pile is reversely rotated and pulled out, so that the trough support pile can be easily re-hit or replaced. 6. Since the mounting portion for mounting the trough support is provided at the fitting portion at the upper end of the pile main body, the mounting of the trough support is facilitated. 7. Since the pile body are a metal pipe-shaped, are lighter than those made of concrete, become easy to handle in transport and on-site at the track. 8. Since the blades are provided separately at the lower end and the upper end in the longitudinal direction of the pile main body, the number of blades is reduced, so that the blades can be inserted into the ground with weak force. Since it penetrates inside, the stability of the trough support pile after the penetration is also ensured. In addition, the smaller the number of blades, the easier the mounting to the pile main body, and the lower the cost.

According to the trough support structure of the present invention, a trough support is attached to two or more trough support piles which are inserted into the ground at intervals, and the trough is installed on the trough support, so that the trough is stable. The horizontal level is secured, and the cable is less likely to be damaged. Also, the fitting part of the trough support pile is
