Problems solved by technology

By laying the interlayer drainage device on the upper part of the geogrid to accelerate the consolidation of the muck, the water in the construction dregs will be collected in the drainage pipe through the interlayer drainage device and discharged, so as to improve the restraint of the reinforcement material on the soil and solve the problem of construction dregs Resource problem

Embodiment Construction

[0020] Below in conjunction with specific embodiment and accompanying drawing, the present invention is described in further detail:

[0021] 1. Remove debris on the surface, excavate the foundation, compact the base, and lay a gravel cushion (9) on the flat and compacted foundation. The gravel cushion (9) should exceed the reinforced soil retaining wall strip The outer side of the shaped foundation (9) is more than 1m, and the positions of the reinforced concrete strip foundation (8) and the drainage ditch (7) should be reserved, and the reinforced concrete strip foundation (9) should be poured at the reserved position Foundation (8) and gutter (7).

[0022] 2. Install the horizontal drainage pipe (5) and the first layer of vertical drainage pipe (4) on the gravel cushion (9), and use the sleeve (15) to connect the first layer of vertical drainage pipe (4) to the horizontal drainage pipe. The tubes (5) are connected as a whole.

[0023] 3. Fill the construction dregs filler...

Abstract

The invention discloses a geogrid reinforced earth retaining wall based on construction waste and a construction method. The reinforced earth retaining wall mainly comprises waste packing, geogrids, aprefabricated concrete panel, interlayer drainage devices and drain pipes. In order to guarantee confinement performance of the geogrids for the waste packing, on one hand, gradation of the waste packing nearby the geogrids is controlled, on the other hand, the interlayer drainage devices are laid at the upper parts of the geogrids, and water is collected into the drain pipes by the interlayer drainage devices and discharged in a unified manner, so that pore water pressure of the packing can be effectively reduced; the geogrid reinforced earth retaining wall is fast to consolidate, stable inmechanical property, short in construction time and low in cost, environmental protection is facilitated, and construction waste is recycled to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of reinforced soil, and in particular relates to a geogrid reinforced soil retaining wall structure based on construction dregs and a construction method thereof. Background technique [0002] At present, with the acceleration of the urbanization process, the construction industry is also developing rapidly at the same time. The construction of roads, excavation of foundation pits, construction of subways, etc. generate a particularly large amount of construction waste every year. Since the construction dregs contain a lot of cohesive soil, drainage and consolidation will be difficult, so it can neither be used for recycled aggregates nor recycled fillers. At present, the treatment methods of muck are basically landfill and stacking, which will cause great harm to the environment and increase the subsequent treatment costs. In December 2015, a landslide accident occurred at the Hong'ao muck receiving field ...
