The invention relates to a concrete faced rockfill dam water stop mortar bed construction trolley which comprises a frame. The frame and an electric winding machine installed on the top of a dam are connected through a traction steel wire rope. The bottom of the frame shares the same degree of inclination with a dam body. Wheels are arranged on the bottom of the frame. A mortar storing tank is arranged on the frame. A mortar pulling mold is arranged at the bottom of the mortar storing tank. A discharging opening of the mortar storing tank is located in the mortar pulling mold. According to the concrete faced rockfill dam water stop mortar bed construction trolley, the mortar storing tank and the mortar pulling mold on the construction trolley are matched and walk up and down under the drive of the electric winding machine along the center of a concrete face open seam. Thus, the amount of mortar needed in a mortar bed groove of a control panel can be accurately controlled, construction quality of a mortar bed is ensured and in addition, the construction trolley walks from bottom to top and the mortar is arranged from bottom to top. No damage will be caused to the paved mortar bed and the surface evenness of the mortar bed will not be affected.
Description
[0001] This application is a divisional application of a patent application titled "Construction Trolley for Water-stop Mortar Cushion of Concrete Face Rockfill Dam", filed on October 26, 2013, and with application number "2013105103813". technical field [0002] The invention relates to the field of mortar cushion construction under copper water-stop sheets of face rockfill dams in water conservancy projects, in particular to a construction device and method for a face-face dam water-stop mortar cushion. Background technique [0003] The current construction method for the upstream slope of face rockfill dams in water conservancy projects is to use a mobile side wall extrusion molding machine on the upstream slope to layer the mixed concrete materials with low grade and good water permeability in trapezoidal sections. A sloping wall made of superimposed slopes. It can be used not only as a supporting surface for concrete face construction but also as a retaining wall for fi...
