The present invention relates to a method of constructing a J type roadside drain and a sliding form to allow to install and construct a J-type roadside drain rapidly and safely with inexpensive costs by a mechanized construction method without using a form. The method of constructing the J-type roadside drain comprises: a first step of applying concrete primarily to fit the height of a first upper projection portion using the sliding form and a concrete casting apparatus on the ground and forming a drain body; a second step of sticking and curing a steel reinforcement in the upper side of the other side of the drain body of the first upper projection portion in a curing process before the drain body is completely solid; and a third step of forming a second upper projection portion using the sliding form and the concrete casting apparatus in order to surround the steel reinforcement when the drain body stuck with the steel reinforcement in the second step is completely solid and constructing the J-type roadside drain. The sliding form comprises: a first casting portion and a second casting portion which have an opened space to which the concrete is injected and which are symmetric each other; a first partition portion and the second partition portion which are longitudinally extended in order to divide the first casting portion and the second casting portion into a first section and a second section; a first vibration mounting portion which is adhered to the first partition portion and the second partition portion and is extended to the center of the first section; a second vibrator mounting portion which is adhered to the wall of the first section and is extended to the center of the first section; and a third vibrator mounting portion which is adhered to the wall of the second section of the first casting portion and the second casting portion and is extended to the bottom side of the first partition portion and the second partition portion. |
