[0023] See figure 1 The construction method of the present invention is as follows:
[0024] Construction survey
[0025] The construction survey is carried out in accordance with the usual soil filling roadbed construction methods, including restoring the center line of the roadbed, detecting the elevation of the underlying layer, measuring the elevation of the middle and side piles, and fixing the elevation piles to prepare for the paving of the coal gangue roadbed. The coal gangue is constructed by layered filling.
[0026] Bound soil construction
[0027] Before filling each layer of coal gangue, fill the edging soil of the same layer as the coal gangue, and pre-compact it to make it 5-8cm higher than the predetermined loose paving thickness of the same layer of coal gangue. After the coal gangue distribution of the same layer is completed, it will be compacted simultaneously with the coal gangue filling of the layer to increase the structural integrity. The edging soil is fill...
