Embodiment Construction

[0035] The following is attached Figure 1-4 The application is described in further detail.

[0036] The embodiment of the present application discloses a tiling device. refer to figure 1 and 2 , the tiling device includes a frame 1, the distance between the two sides of the frame 1 is equal to the width of the roadbed; four groups of rollers 2 are fixed on the lower end of the frame 1, and the upper end of the frame 1 is rotatably connected with a rotating shaft 3, and the rotating shaft 3 is covered Geotextile roll; when the frame 1 was transported forward, the geotextile 17 was unrolled and laid flat on the lower bearing layer.

[0037] Wherein, the upper ends of both sides of the frame 1 are respectively fixed with a half ring 1 4, the opening of the half ring 1 4 faces upwards, and the opening end of the half ring 1 4 is connected with a half ring 2 5 by hinge rotation, and the half ring 5 is connected with the half ring 4. The other end of the second 5 relative to t...

Abstract

The invention relates to a soft soil roadbed geosynthetic material three-dimensional reinforcement treatment construction method, which comprises the steps of 1, treating a lower bearing layer, and compacting and leveling the lower bearing layer; 2, laying geotextile, specifically, flatly laying the geotextile on the lower bearing layer, and partially overlapping the adjacent geotextile together;3, laying geogrids, specifically, laying the geogrids on the geotextile, enabling the widths of the two sides of each geogrid to be the same as the width of the roadbed, and partially overlapping theadjacent geogrids together; 4, laying a graded gravel cushion layer, laying gravel on the geogrids, and compacting the gravel layer; and 5, laying a gabion box, filling the gabion box with human headstone and a gravel cushion layer, laying the gabion box on the graded gravel cushion layer, and then feeding the human head stone and the graded gravel a to the gabion box in the mode that the human head stone is taken the main material and gaps are filled with the graded broken stone. The construction method has the effects of increasing the construction speed and reducing the construction cost to a certain extent.

Description

technical field [0001] The present application relates to the field of reinforcement of soft soil roadbeds, in particular to a construction method for three-dimensional reinforcement of geosynthetic materials for soft soil roadbeds. Background technique [0002] At present, the traditional treatment methods for soft soil subgrade mainly adopt filling replacement, soil curing agent method, composite pile method, etc. In the case of thick clay layer, the replacement filling method is relatively deep and prone to uneven settlement in the later stage of construction. The cost is high. The soil curing agent method cannot be fully mixed with the soil with high moisture content because the curing agent cannot be fully mixed, so the reinforcement effect is not very ideal. The composite pile method has high cost, high mechanical equipment, and poor applicability. [0003] In view of the related technologies mentioned above, the inventor believes that it is necessary to study a method...
