Problems solved by technology

Using the construction method of sliding the mortar from the dam crest along the slope to the tank from top to bottom and smoothing it with artificial cloth, the existing problems are that the speed and the amount of the material are not well controlled, and the second is that It is very difficult to meet the quality requirements of the flatness of the mortar cushion, leaving quality hidden dangers for the later installation of copper water-stop sheets

Embodiment Construction

[0026] Such as figure 1 Among them, the overall structure of the mortar cushion layer 7 and the copper water-stop sheet 3 located at the joint of the dam body is as follows: a mortar cushion layer 7 is provided in the mortar cushion layer groove 1, a PVC gasket 2 is arranged on the mortar cushion layer 7, PVC The gasket 2 is provided with a copper waterstop 3, the copper waterstop 3 is provided with a composite waterstop 4, and a rubber rod 5 is provided at the bend of the nose of the copper waterstop 3, and the nose of the copper waterstop 3 The inside is also filled with polyurethane foam filler 6. The installation quality of the copper water stop 3 is closely related to the quality of the mortar cushion 7.

[0027] Such as figure 2 Among them, a construction trolley for the water-stop mortar cushion of a face rockfill dam includes a vehicle frame 8, which is connected to an electric winch 17 installed on the dam crest through a traction wire rope 16, and the center line ...

Abstract

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

technical field [0001] 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 trolley for face rockfill dam water-stop mortar cushion layers. Background technique [0002] 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 filling dam body slag. [0003] Since the trapezoidal section extruded by the side wall extruder is used to layer the inclined wall along the outer slope, the flatness between each layer is not very good, and there are often staggered platform...
