Abstract

To provide a method with respect to a construction method natural stone pavement in which a fluidized object or CA mortar is poured in a void of a crushed stones or aggregate of spacers laid between a lower surface of a natural stone pavement surface layer block of natural stones and a base layer, to prevent an injection cylinder with a hole leading to an outside from moving during a crushed stone laying work when the cylinder is installed on the base layer and interfering with the laying work.SOLUTION: A polygonal cylinder, or a cylinder with a member or a fall prevention object so that a bottom side portion of the cylinder is parallel to a base layer surface is installed, instead of a cylindrical cylinder. A purpose of using the cylinder with a flat bottom portion is that it can be stably installed on the base layer.SELECTED DRAWING: Figure 1

Description

舗装断面の構造は、一般的に舗装表面から表層、モルタル層、基層、路盤、路床の構造になっている。自然石の舗装表層材ブロック（以下、ブロックという。）の下面と基層間に敷きつめられたスペーサーの砕石または骨材の空隙に流状体の物質やＣＡモルタルを注入する工法は公知である。
基層上に円筒形の筒を設置し、この筒からＣＡモルタルを流し込み、骨材からなるスペーサー組織へＣＡモルタルを筒内から筒外へ流出させる工法も公知（特許庁・特許願・受付番号２１９０１６９００９１）である。
本発明は、基層上に円筒形の筒ではなく、多角形の筒［本文：特許請求の範囲１］、または筒の底辺部が基層面と並行になるような部材［本文：特許請求の範囲２］もしくは転倒防止の物体を有する筒を設置することを目的としている。
多角形の筒を使用する目的は、円筒形の筒より筒の製作費が安価になる場合があること。また基層上に筒を設置した時にスペーサーの砕石の敷き均し作業途中で筒が移動し、敷均し作業を妨害することを防ぐことである。
底部が平面の筒を使用する目的は、基層上に安定して設置できるからである。筒底部に安定版を設置する目的は、スペーサーに使用する砕石を基層上に敷均し時に筒を移動しにくくするためである。The structure of the pavement cross section is generally the structure from the pavement surface to the surface layer, the mortar layer, the base layer, the roadbed, and the roadbed. A method of injecting a flowing substance or CA mortar into the voids of crushed stone or aggregate of a spacer laid between the lower surface of a pavement surface layer material block (hereinafter referred to as a block) of natural stone and the base layer is known.
A method is also known in which a cylindrical cylinder is installed on the base layer, CA mortar is poured from this cylinder, and the CA mortar is discharged from the inside of the cylinder to the outside of the cylinder into a spacer structure made of aggregate (Patent Office, Patent Application, Receipt No. 21901690091). ).
The present invention is not a cylindrical cylinder on the base layer, but a polygonal cylinder [text: claims 1], or a member such that the bottom of the cylinder is parallel to the base layer surface [text: claims]. 2] Or, the purpose is to install a cylinder with an object to prevent it from tipping over.
The purpose of using a polygonal cylinder is that the manufacturing cost of the cylinder may be cheaper than that of a cylindrical cylinder. Further, when the cylinder is installed on the base layer, the cylinder is prevented from moving during the laying work of the crushed stone of the spacer and interfering with the laying work.
The purpose of using a cylinder with a flat bottom is that it can be stably installed on the base layer. The purpose of installing the stable plate on the bottom of the cylinder is to make it difficult for the cylinder to move when the crushed stone used for the spacer is laid on the base layer.

図１は、ＣＡモルタル工法において舗装体の基層上のスペサーを構成するＣＡモルタル硬化体の作成時に使用するところの舗装体の基層上に設置する多角形の筒である。この筒の中へＣＡモルタルを流し、筒に開けた壁孔からスペーサー組織の砕石層空隙部にＣＡモルタルを流出させるものである。数１は基層上に設置する筒である。数２は、この筒の壁に開けた孔である。 FIG. 1 is a polygonal cylinder installed on the base layer of the pavement body, which is used when preparing the hardened CA mortar body constituting the spessor on the base layer of the pavement body in the CA mortar method. The CA mortar is poured into the cylinder, and the CA mortar is allowed to flow out from the wall hole formed in the cylinder into the crushed stone layer void portion of the spacer structure. Equation 1 is a cylinder installed on the base layer. Equation 2 is a hole made in the wall of this cylinder. 図２は、基層上に設置する多角形の筒の形状断面を示した例である。数３は、断面形状が三角形の筒の断面である。数４は、断面形状が四角形の筒の断面である。数５は、断面形状が半円形の筒の断面である。数６は、断面形状が楕円形の筒の断面である。数７は、筒の底部に筒が移動しづらくなるように底部に安定版を付けた筒の断面である。 FIG. 2 is an example showing a cross section of a polygonal cylinder installed on the base layer. Equation 3 is a cross section of a cylinder having a triangular cross-sectional shape. Equation 4 is a cross section of a cylinder having a quadrangular cross-sectional shape. Equation 5 is a cross section of a cylinder having a semicircular cross-sectional shape. Equation 6 is a cross section of a cylinder having an elliptical cross section. Equation 7 is a cross section of a cylinder having a stable plate on the bottom so that the cylinder does not easily move to the bottom of the cylinder.
