A slip form or mule for continuously laying concrete along one or more adjacent lanes on the sloping side of a contoured drainage ditch. The slip form is affixed to or movably mounted from a construction machine that travels along the top berm of the ditch. A tool frame support slideably contains a form having an open top and bottom with longitudinally adjustable and segmented side walls and is suspended from cooperating derrick and pivotal frame supports along the side of the machine for registry with and travel spaced above the sloping side of the ditch. A flexible finishing pan follows the form means in the plane of its bottom edges and includes adjustable supports suspending or compressing the pan in relation to the concrete slab being laid. The tool frame support has a pair of rigid vertical spaced side walls with outwardly directed opposite and coplanar bottom flanges which slideably guide the adjustable side walls of the form as it is moved to adjust to the width of the ditch side wall or to the desired width of the slab. The tool frame support is longitudinally pivoted from the frame of the machine on an axis that extends along and above the top portion of the ditch and is carried by one or more adjustable extensions at about the midpoint of the tool frame support. |
