Description

[Detailed explanation of the invention] (a) Industrial application field This invention is used to create barriers and drainage ditches to temporarily prevent the entry of vehicles, etc. at the boundary between roads and parking lots and other public squares. It is about structures and their combinations.

(b) Conventional technology Conventionally, to prevent the entry of vehicles, etc., structures using collapsible iron plates were temporarily installed at the required locations, or cylindrical metal containers were vertically placed underground. The common method was to bury the cylinder, and if necessary, pull out the cylinder used for the framework above the ground and fix it for use.

(c) Problems that the invention aims to solve However, these fences may be removed without permission, require a considerable amount of work to construct because they are buried deep underground, and the spacing between the blocks is fixed due to their structure. There were many cases where the result was lost due to mischief.

In addition, fences to prevent these vehicles from entering are often installed at the boundary between roads and plazas, etc. In this case, it is necessary to separately install a drainage ditch as a side gutter for the road or plaza, which poses a cost problem. It was hot. The present invention aims to eliminate these drawbacks.

(d) Means for solving the problem To explain this invention based on drawings, it consists of a rectangular steel pipe-shaped drainage groove 3 with a linear cutout 2 on a smooth surface 1 made of a steel plate, and its inner surface. a base portion 4 of the stake that is approximately inscribed with a slight margin along the line and that fits loosely in the drainage ditch; a main body portion 5 of the stake that is connected and integrated with this and is loosely inserted through the cutout of the drainage ditch; This is supported by the surface part 1 of the drainage ditch.
The structure is characterized in that the end of the drainage ditch is provided with wheels 6 for sliding the pile, and the end of the drainage ditch is provided in the catch basin 7, and the pile is inserted or removed from the same place.

(E) Function According to this idea, the drainage ditch is easy to construct by simply burying it underground, except for the surface part, and there is no need to excavate the ground deeply, and rainwater on the road surface can be drained through the straight cut part. The water flows into the drainage ditch and is drained as sewage through the catch basin connected to the end of the ditch, while the wheels that are inserted through the opening at the end of the ditch provided in the catch basin can easily and smoothly drain water. The groove surface portion can be slid.

In addition, in order to fix the piles that are inserted one after another at intervals necessary to prevent vehicles from entering, it is possible to connect the pile bodies to each other with chains, or to connect the piles and the drainage ditch. However, in order to avoid complicated handling and to make it difficult to remove from the outside, small holes 8 or hooks are provided in the base part 4 of each pile located in the drainage ditch, and the length is determined according to the required spacing. You can prevent each pile from moving by connecting each pile by pulling a chain in sequence, and securing both ends of the chain in a water collection basin. It is also possible to pull the end of the chain and use it as an auxiliary means for movement.

Furthermore, in order to prevent the piles from being removed without permission, it is sufficient to provide a lid 9 on the catchment basin where the opening at the end of the drain exists and lock it. If drains of the same type are installed in the same direction, these drains can be relocated and moved when the walls installed in one direction are unnecessary. It is also possible to store and store a large number of stakes in an orderly manner in a drainage ditch laid in a place where there will be little hindrance.

Note that the linear incision at the top of the drainage ditch can be made to prevent bending and damage by bending the punched steel plate, etc., depending on the thickness of the steel plate used for the pile. The thickness of the steel plate can be kept at around 5mm, and the width of the incision will not be more than 1cm, so it will not pose a danger to pedestrians.
It is also possible to provide appropriate small holes in the top surface to function as drainage channels, and depending on the shape of the installation location, it is also possible to design and construct the pile in a gentle curve within the range that allows the pile to move.

(f) Effects of the invention According to this invention, there is no need to separately provide fences and drainage ditches, and fences can be installed and fixed at arbitrary intervals to temporarily prevent the entry of vehicles, etc., and removed if necessary. It has great practical value in terms of its range of use and economical effects on construction.
