JPS60102426A - Slope protection block - Google Patents

Abstract

PURPOSE:To shorten the construction period of slope protection blocks as well as to make the slope protection work easier by using an integrally formed block whose plane is of square or rectangular form and having a cylindrical cavity penetrating through its central part thicknesswise. CONSTITUTION:A block 1 having a cylindrical cavity in its central part is integrally formed by utilizing centrifugal force, having angled or beveled faces at X- and Y-positions. The block 1 also has projections as countermeasures against rain water on its surface. The homogeneous concrete blocks capable of well draining rain water and also of preventing slipping-down and containing usual reinforcing bars inside can be obtained.

ックに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stop block, and more particularly to a block that can be easily constructed on slopes on both sides of a road without much effort and that maintains uniformity.

してゆかねばならないから手間もか＼す、施行工期も永
くなり易く、技術も所要されるという欠点がある。As for conventional such blocks, each company has different types of blocks, and the way the blocks are interlocked is also different. For example, some commercially available legal frame blocks have 8 blocks of A, B, and O.
There is a Hodome block in which Hodome construction is done by combining and using blocks of each type. Although there is an advantage in this case, it is also time-consuming and the construction period tends to be longer because each individual block, A block, B block, and 0 block, must be finished while being combined. The disadvantage is that it requires a lot of skill.

濃度にも十分配慮せねばならないという欠点もある。In addition, blocks are manufactured by pouring concrete into molds, and in order to ensure uniformity without creating air bubbles in every corner of the mold, careful consideration must be given to the composition and concentration of the concrete components. There is also a drawback.

又従来から法とめブロックはブロック中央部の空いたと

自身が下方に滑り落ち易いといった欠点もある。Traditionally, the open space in the center of the block is filled with roses and grass, but when it rains and the slope is high and continues upwards, rain water from above is used. Therefore, there is a disadvantage that the ballast or grass in the center of the block below is damaged, and on the other hand, the block itself tends to slide downward.

The purpose is to provide a homogeneous block.

It has an inner diameter equal to , a height hl of 10 to 15 wn, and a thickness d of 10 to 15 WIn. Also, according to Figure 8,
On the lower edge of the front side of the pull block, there is an isosceles triangular plate with a base length equal to the length of the lower edge of the block, a height of about 40 mm, and a thickness of about 10 mm. In this way, rainwater flowing down from above the block is drained well and does not damage the ballast filling area in the center of the block or the lawn, which is an advantage, and the protrusion on the back side prevents the block itself from slipping. You can also get this advantage.
