Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an improvement in gutter blocks.

(Prior art and its problems) There are two types of side gutters: those made using the trough construction method and those made using the connected block construction method.

A trough is formed by integrally forming the river bed and slope of a gutter. For example, trough 1 in Figures 5 and 6
0 is a U-shaped quadrangle in which a U-shaped groove 10a is formed. These troughs 10 are buried in a continuous manner in the front-rear direction (front and front sides) in Figure 5, and joints are created between each trough 10 to form a gutter, but there are the following problems. .

Because the slope and river bed are formed as one piece, cracks are likely to occur due to stress caused by earth pressure, freezing, etc. Additionally, the depth of the gutter is determined by the trough used and cannot be changed.

The connected block construction method involves combining river bed blocks and slope blocks and binding them with steel wire or the like to construct a gutter, but it has the following problems.

When combining the riverbed block and the slope block, the width of the riverbed varies. In addition, there are many joints, which makes it easy for water to run away and leak, causing water to flow behind the block and wash away earth and sand, which can easily cause damage to the river bed.

(Technical Problem) The present invention was made to solve the above-mentioned problems.The technical problem to be solved by the present invention is to form part of the slope part on both sides of the river bed integrally, The purpose is to make it easy to attach slope blocks on both sides and to avoid being affected by frozen earth pressure.

(Structure) The gutter block of the present invention has substantially mountain-shaped embankments narrow on the upper side and wide on the lower side on both sides of the riverbed, and in the embankment, from the outer slope to the bottom of the lower side of the riverbed. It is characterized by having a through-hole for the mounting hole.

(Embodiment) An embodiment of the present invention will be explained with reference to FIGS. 1 to 3. The figure shows a concrete gutter block 1
It is.

The gutter block 1 is constructed by integrally forming embankment parts 3 having a triangular mountain cross-section on both sides of a river bed part 2 which is formed into a flat plate having a substantially square plan view.

Two attachment holes 4 each having a long cross section are perpendicularly drilled through the outer slope of each embankment portion 3.

The mounting hole 4 is used to position a slope block (described later) that is continuous with the embankment section 3 through a steel wire or the like.

An example of the gutter using the gutter block 1 is shown in the fourth example.
To explain with reference to the drawings, first, the ground A is dug and gutter blocks 1 are buried in a continuous manner, and slope blocks 5 are arranged on the outer slope 3a of the embankment 3 of each block 1.

The slope block 5 is a substantially square plate material in which a through hole 6 that is continuous with the mounting hole 4 of the gutter block 1 is bored.

A steel wire 7 is passed through each of the attachment holes 4 and through holes 6 and bent into a U shape to connect the gutter block 1 and the slope block 5, and the blocks 1 and 5 are bound together continuously.

The groove depth in the side gutter can be changed by using slope blocks 5 of different lengths or by changing the number of slope blocks 5 arranged in a row in the height direction, which is very flexible.

(action, effect) According to the present invention, there are the following functions and effects.

Since a part of the slope is formed integrally with the riverbed, the number of joints in the riverbed is reduced, reducing water run-off and water leakage.

It is convenient because an arbitrary gutter depth can be obtained by changing the length of the slope block provided on the embankment of the gutter block.

By using the mounting holes in the embankment of the gutter block, the slope block can be mounted accurately. The slope blocks can move freely according to the strength of the frozen earth pressure, and the initial state of construction can be maintained for a long period of time without cracking unlike a U-shaped trough.

Claims (1)

[Scope of utility model registration request] This gutter block has almost mountain-shaped embankment parts narrow on the upper side and wide on the lower side on both sides of the riverbed part, and in the embankment part, a mounting hole is drilled through the embankment part to reach the bottom surface on the lower side of the river bed.
