JPH0953275A - Box type street drain block - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate cast-in-place concrete work other than the foundation and lid installation work to a conventional street drain, make it possible to reduce a construction period because of being good enough to install only a box type street drain block, adjust a channel with crushed stone, etc., instead of ready mixed concrete casting in a ground variable place and to economically manufacture it as a product. SOLUTION: Footing cobble stone 1 and footing concrete 2 with specific height are constructed, and in a box type street drain block installed on them, a mounting section of a joint metal fixture is formed in the joint end of the box type street drain block 4 to form an opening section in the top slab. Then, a block for head is provided to the end on the joint side inside the box type street drain block 4, and the projected bottom slab is provided on one side at a right angle lengthwise of the box type street drain block 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box-shaped gutter block for collecting sewage, rainwater and the like.

[0002]

2. Description of the Related Art Conventionally, foundation stones are laid and foundation concrete is placed thereon. The finished surface of the upper end of the base is made smooth and the variable side groove is installed. The height is adjusted with a floor mortar or liner, and fresh concrete is poured from the opening of the gutter top plate, and invert concrete is placed according to the slope of the water channel. It is generally known that a lid is attached thereafter.

[0003]

However, the invert concrete pouring work is performed by pouring fresh concrete into the invert portion through the top plate opening of the variable gutter in the above-mentioned prior art. However, it is a difficult task because the opening is narrow. Then, after that, I was working on attaching the lid, but this was a manual work and took time. Also, when a car passed over the lid, there was a rattling noise and a noise problem occurred. Also, when using it in a place where the ground height changes, a large amount of ready-mixed concrete was put into the variable gutter to adjust the canal height. In addition, it was uneconomical to use a large amount of ready-mixed concrete. Also, at the head of the head, a head block was constructed by hitting on the spot. And there is a problem that it takes time to work in a narrow place.

In view of this situation, the present invention provides a box-shaped gutter block in which a bottom plate is attached to a conventional variable gutter and integrally molded, and the opening at the top end is replaced with a water collecting hole. In addition, head blocks are attached to both sides of the main body, crushed stones, etc. are packed inside, and the top is inverted with concrete (this should be manufactured at the factory). It is another object of the present invention to provide a box-shaped gutter block in which a drop block is attached within a cross section of one side of the main body.

[0005]

The present invention employs the following technical means in order to solve the above-mentioned problems. In the invention according to claim 1, in a box-shaped gutter block which is constructed by building a foundation stone and concrete at a predetermined height and is installed thereon, a mounting portion of a joint metal fitting is formed at a connecting end of each gutter box block. However, the technical means of forming an opening in the top plate was adopted.

According to the second aspect of the present invention, the first aspect is provided.
In the box-shaped gutter block described, a technical means of providing a drop block at the connection side end inside the box-shaped gutter block is adopted.

According to the third aspect of the invention, a technical means is employed in which a protruding bottom plate is provided on one side in a direction orthogonal to the lengthwise direction of the box-shaped gutter block.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. First, a first embodiment of the box-shaped gutter block will be described in detail with reference to FIGS.

FIG. 1 is a side sectional view showing a box-shaped gutter block. In order to lay the box-shaped gutter block, a laying place is excavated and a foundation stone 1 (thickness: about 100 mm) is laid at a predetermined height. A box-shaped gutter block 4 is laid on the foundation stone 1 through a foundation concrete 2 and a floor mortar 3, and the box-shaped gutter blocks 4 are sequentially connected by a joint fitting 5 or the like in the flow direction of water collection. In addition, 6 is a water collecting hole, 7 is a long bolt, 13
Indicates insert nuts. Needless to say, the water blocking packing 8 is further attached to the connecting end surface.

Next, to provide a drop portion, a drop block 9 is attached on the inner side of both cross sections, crushed stones are packed inside, and an invert portion is finished with concrete 11 on it. By installing this product in a place where the ground height changes, it becomes a gutter that doubles as a retaining wall and can connect water channels continuously (In addition to the above crushed stone, use steel slag or lightweight aggregate. Can also).

Next, with reference to FIGS. 4 and 5, an embodiment in which a head is formed obliquely will be described. The drop blocks 9 are provided at both ends of the box-shaped gutter block 4 in the flow direction of the water collection, and crushed stones 10 are packed in the space surrounded by the drop block 9 and the box-shaped gutter block 4, and the concrete 11 is used for inversion. To finish. This work is done in advance in the factory.

Next, as can be understood from those shown in FIGS. 6 and 7, a product having a bottom plate provided on one side of the main body is used where the ground height changes and also serves as a retaining wall. In some cases. It is provided with a protruding bottom portion 12 provided on one side in a direction orthogonal to the length direction of the box-shaped gutter block 4, and is designed to ensure stability when the box-shaped gutter block 4 is laid. Is.

[0013]

EXAMPLE A concrete example of the mounting means for the drop block 9 will be described. As can be understood from the ones shown in FIGS. 8 to 11, the head block 9 as shown in FIG. 11 formed of rubber, plastic, concrete or the like is used as shown in FIGS. An insert nut 13 is embedded in the inner end portion of the, and is fixed with a bolt 14 or the like via the insert nut 13. Also,
The gap between the standing wall 15 and the bottom portion 16 of the box-shaped gutter block 4 and the drop block 9 is embedded and fixed with joint mortar.

Further, as shown in FIGS. 12 and 13, a mud-storing box-type gutter block 17 for sucking sludge and the like in the underdrain using the head block 9 is used for 10 m or 20.
It is an example in which one location is connected to m. The box-shaped gutter block 17 for mud storage is provided with an opening 18 with a grating.

[0015]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) There is no need for on-site casting other than the foundation and installation work of the lid in the conventional gutter, and the installation period can be shortened by simply installing the box-shaped gutter block of the present invention. (2) In the ground change area, the waterway was adjusted by placing ready-mixed concrete, but by adjusting it with crushed stone and commercializing it, it became economically better. (3) Since the lid is not used, there is no rattling or noise even when the car runs over.
