Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trough support pile used when a trough for accommodating power cables, communication cables and the like is installed on the ground.

[0002]

2. Description of the Related Art When installing the above trough on the ground, a method is used in which the lower half of the trough support pile is buried in the ground and the trough is attached to the upper surface thereof. And as such a trough support pile, a prismatic concrete one is generally used.

[0003]

However, since this conventional concrete trough support pile is heavy and can be stably installed, it requires a considerable amount of labor for transportation to the installation site and installation work. I have a problem to do. In addition, when a trough support pile is manufactured from a plastic material in order to reduce the weight, there is a problem in that the trough support pile lacks stability due to its low weight, and it is easy to pull out from the ground or incline. Therefore, there has been a long-awaited demand for trough support piles that are lightweight, easy to handle, and can be installed in a stable state.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a support pile body made of a plastic material is provided with a space for inflowing earth and sand which communicates with a side opening. It is characterized by being provided.

[0005]

The trough support pile constructed as described above is installed by exposing the upper portion of the main body of the pile to a required height above the ground surface and burying the lower portion of the main body in the ground. The installation of is similar to the conventional one. However, according to the present invention, since the supporting pile main body is made of a plastic material, it is lightweight and easy to handle, and the supporting pile main body is provided with a void for communicating the earth and sand with the side opening. When buried, earth and sand enter the void through the side opening. For this reason, it is possible to prevent slipping out of the soil and inclination regardless of the light weight, and to install in a stable state.

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 4, reference numeral 1 denotes a support pile main body made of a plastic material such as FRP resin or high-density polyethylene resin having a vertically long rectangular frame shape, and the support pile main body 1 has a side opening 1a.
A space portion 1b for communicating with earth and sand is provided. That is, the support pile main body 1 has an upper plate portion 3 stretched between upper ends of a pair of side plate portions 2 and 2 and a lower plate portion 4 stretched at a lower end portion to form front and rear side face portions in side face openings 1a and 1a. In addition, the pair of side plate portions 2, 2 and the upper plate portion 3 and the lower plate portion 4 form the space portion 1b for the inflow of earth and sand.

The supporting pile main body 1 has a side plate portion 2, 2 having a trapezoidal outer side shape in which the width of the upper end edge is shorter than the width of the lower end edge is a trapezoidal vertically long quadrangular shape. The width of the upper plate portion 3 stretched between the upper ends of the is wider than that of the lower plate portion 4 stretched between the lower ends, and the front external shape is an inverted trapezoidal vertically long quadrangular shape. It is trapezoidal in shape and can be prevented from slipping out of the ground. Also, by installing the wide upper plate part 3 as the trough mounting surface,
A large trough 21 as shown in FIG. 1, FIG. 2 and FIG.
By installing the narrow lower plate portion 4 as a trough mounting surface, it is possible to cope with a small trough 22 as shown in FIG.

Reference numeral 5 denotes a stabilizing plate which also serves as a reinforcing plate stretched over the intermediate portions of the side plate portions 2 and 2 of the supporting pile body 1 at a required interval, and 6 denotes an intermediate portion in the front-rear direction of each stabilizing plate 5. Reinforcement plates stretched between them, 7 and 7 are side plate parts for attaching auxiliary stabilizer plates 8 for tensioning the wing plate parts to the outsides of the side plate parts 2 and 2 in order to enhance stability when installed on soft ground. A rectangular tube portion 9 which is a window hole provided in the side plate portions 2 and 2 and which also functions as a stabilizer plate through which the auxiliary stabilizer plate 8 can be inserted is provided between the window holes 7 and 7 integrally with the side plate portions 2 and 2. The front plate portion 10 and the rear plate portion 11 of the square tube portion 9 are provided with screw mounting holes 12 for inserting screws for fixing the auxiliary stabilizing plate 8.

The thus constructed structure is the main body 1 of the supporting pile.
The upper part of the above is exposed to the required height from the ground surface and embedded in the ground, and the trough connecting portion is attached to the upper surface of the support pile main body 1, that is, the upper plate portion 3 by means of screwing or the like. Moreover, according to the present invention, since the supporting pile main body 1 is made of a plastic material, it is lightweight and easy to handle, and does not require much labor for transportation to the installation site and installation work.

Further, when the lower part of the supporting pile main body 1 is buried in the ground, the side opening 1a is formed in the space 1b of the supporting pile main body 1.
Since the earth and sand enter from the ground, the support pile main body 1 can be prevented from slipping out of the ground and tilting even though the main pile body 1 is lightweight, and can be installed in a stable state. Further, when the stabilizer 5 is stretched over the side plate portions 2 and 2 of the support pile body 1 at a required interval as in this embodiment, the stabilizer 5 comes into contact with the earth and sand. Therefore, it can be installed in a more stable state.

[0011]

EFFECTS OF THE INVENTION As is clear from the above description, the trough support pile of the present invention is handled because the support pile main body made of plastic material is provided with the space portion for the inflow of earth and sand which communicates with the side opening. It is easy to install, and the earth and sand flow into the space during installation, so it can be installed in a stable state. Therefore, the present invention is of great practical value as a solution to the conventional problems.
