Abstract

PROBLEM TO BE SOLVED: To produce a curb stone with an integrated drainage pipe for discharging a water pool on a sidewalk as a barrier-free measure in a sidewalk pavement to a roadway side at a factory.
The present invention provides a drainage device for draining by providing a drainage pipe penetrating from the roadway side to the sidewalk side at an angle of 0 ° to 35 ° and penetrating through the base of the curb. It is a curb that is included. Since the drain pipe is included, the product is standardized and the accuracy is significantly increased. In addition, since the drain pipe is included in the curbstone, there is no need for the construction of the drainage function device, so that the construction is extremely easy and the economic effect is great.

Description

  The present invention relates to a curb stone in a drain pipe laid along a boundary between a sidewalk and a roadway.

  In large suburban roads and urban areas of the town, concrete blocks are arranged side by side between the sidewalk and the roadway to define the boundary of the roadway. The concrete block is a rectangular cube with a trapezoidal cross section and is molded from concrete. It is generally called a curb. As a conventional drainage method from the curbstone, there is an L-shaped pedestrian boundary block that directly flows into a water collecting basin provided on the surface of the roadway without flowing into the roadway side. And there is concrete for drainage. In addition, there is a curb that is provided with a groove in the curb itself to allow rainwater on the sidewalk to flow into the roadway. Similarly, there is a curb that is integrally molded with a drainable curb sandwiched between the curb base and the curb top.

  Since conventional drainage hardware is mounted manually by humans, it may protrude from the upper surface of the curb, and during winter snow removal work, the drainage hardware gets caught on the blade of the snowplow grader and breaks. It is possible to end up. Moreover, it can be considered that it takes a considerable amount of time to install the drainage hardware.

  The present invention is an application for improvement by the same person who has already obtained a patent for the curb stone in the drainage device.

  JP-A-2005-231299

  In the current construction method, the installation of conventional drainage hardware is uneven in accuracy, and during winter snow removal work, the drainage hardware is damaged by getting caught on the blade of the snowplow grader and spending time on construction There is.

  An object of the present invention is to solve such a conventional problem, and an object of the present invention is to realize a curbstone which can be efficiently attached with a drainage metal and has a constant accuracy and is not likely to be damaged.

Means to solve the problem

  In order to achieve the above-mentioned object, the present invention is one in which a drain pipe is enclosed in a curbstone at a factory and is struck together to be integrally molded.

  Explaining with reference to the drawings, if the height of the road surface 1 and sidewalk surface 2 in Fig. 1 and Fig. 2 is the same, or if the height of the sidewalk surface 2 side is higher than the road surface 1 side, all drain pipes The thickness of the concrete between the drainage pipe enclosed in the concrete curb and the drainage pipe on the sidewalk side of the drainage pipe and the drainage pipe contained in the concrete curb is set to a thickness that does not peel off the concrete. By doing so, it is not necessary to cover the drain pipe with a plate material.

Effect of device

  As described above, the curb stone in the drainage pipe of the present invention is an epoch-making work that can be laid at the same time as the drainage pipe function in exactly the same way as a conventional curbstone with high accuracy and standardization in factory production. Can provide a typical drainage stone.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  1 and 2 show a drain pipe internal margin stone according to the present invention. The drainage pipe inclusion curb is integrally molded with the drainage pipe 3 enclosed in the curbstone.

  There are a casting method and a bi-con method as a method for integrally forming drainage pipes and curbs.

  First, a general casting method will be described. The jig which fixes a drain pipe is attached to the wall surface of the conventional casting curb form, the drain pipe 3 is put there, and ready-mixed concrete is cast.

  Next, the bicon method will be described. The Bicon method is super hard concrete that is molded by compaction of wave vibration and compression with a water / cement ratio of 38% or less. Since considerable vibration and pressure are applied, a rod having a length that hits the wall surfaces on both sides of the mold is fixed to the drain pipe 3. After that, in the same way as the pouring method, it is attached to a conventional form frame for bicon curb, injecting super hard concrete, and molding by compaction of wave vibration and compression.

  In the present embodiment, the material of the drainage pipe 3 is a steel square pipe and galvanized coating as a rust preventive. Other than that, it can be made of stainless steel, aluminum, FRP, etc., and the material and surface coating are not particular. In addition to square pipes, round pipes, handmade products, etc. may be used as drain pipes, and the shape and size are not particularly particular.
