CONSTRUCTION METHOD OF BOX CULVERT, AND PROTECTIVE SHEET FOR CONSTRUCTING BOX CULVERT CONNECTION JOINT
To provide a method for constructing a box culvert which can be easily constructed at the site.SOLUTION: When a box culvert formed of a concrete box body continuously arranged body is constructed in which concrete box bodies 1 having a hollow part 1a are serially arranged so that the hollow part 1a connects each other and a connection joint between the concrete box bodies 1 is filled with a joint 2, at least a hollow side ceiling portion of the connection joint part is covered with a protective sheet 3 having a base material layer formed of a glass cloth filled with a silicone rubber cured product having 10 to 90 hardness by Durometer A hardness meter and a silicone rubber cured product layer that is provided on one surface of the glass cloth and has 10 to 90 hardness by Durometer A hardness meter, and a silicone adhesive layer that is stacked on the silicone rubber cured product layer and has 1 to 60 Asker C hardness; and an adhesive layer is stuck or bonded to a concrete wall of the concrete box bodies 1 to prevent falling and outflow of a joint material from an adhesive joint part.SELECTED DRAWING: Figure 4
【課題】現場で簡単に施工が可能なボックスカルバートの施工方法を提供する。【解決手段】中空部１ａを有するコンクリート函体１相互をその中空部１ａが連通するように連設し、コンクリート函体１間の接続目地部に目地材２を充填して施設したコンクリート函体連設体よりなるボックスカルバートを施設する際に、接続目地部の少なくとも中空部側天井部分に、デュロメーターＡ硬度計による硬さが１０〜９０のシリコーンゴム硬化物で目止めされたガラスクロス及び該ガラスクロスの片面上に設けられたデュロメーターＡ硬度計による硬さが１０〜９０のシリコーンゴム硬化物層からなる基材層と該シリコーンゴム硬化物層上に積層されたアスカーＣ硬度で１〜６０のシリコーン系粘着層とを有する保護シート３を被覆し、粘着層をコンクリート函体１のコンクリート壁に粘着又は接着して、接着目地部からの目地材等の落下流出を防止する。【選択図】図４
