Problems solved by technology

[0004] At the same time, with the development of the economy, the total amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Landfill, this treatment method not only takes up a lot of land resources, but also causes serious environmental pollution

Embodiment Construction

[0032] The invention is described in detail below in conjunction with accompanying drawing and embodiment 1:

[0033] Such as Figure 1 to Figure 4 As shown, a geocell 5 reinforced sand cushion doped with construction waste mainly forms a honeycomb three-dimensional three-dimensional structure from a plurality of construction waste layers 1 and reinforced structure layers 2 intersected in the foundation from bottom to top. The construction waste layer 1 is mainly formed by compacting waste concrete 4 after crushing treatment, the reinforced structure layer 2 is a geocell 5, and the bottom of the geocell 5 partially intersects with the construction waste layer 1 below The middle and upper parts of the geocell 5 are filled with sand 3, and a sand layer is formed above the geocell 5, and another construction waste layer 1 is arranged on the sand layer.

[0034] Both the construction waste layer 1 and the reinforced structure layer 2 are 2-4 layers, each of which is 2 layers in t...

Abstract

The invention discloses a building waste-doped geogrid cell reinforced sand blanket and a construction method. The geogrid cell reinforced sand blanket mainly consists of a plurality of building waste layers and reinforced structure layers which are crossly arranged in a ground foundation from bottom to top; each building waste layer is formed by compacting and paving the crushed waste concrete; each reinforced structure layer is a geogrid cell; the bottom part of each geogrid cell is partially crossed with the building waste layer thereunder, sand is charged to the middle part and upper part of each geogrid cell, and a sand layer is formed above each geogrid cell; another building waste layer is arranged on each sand layer. The geogrid cell reinforced sand blanket has the advantages that the main body materials are building wastes and geogrid cells, so that the problem of building waste filling is solved, the resource is saved, and the manufacturing cost of project is reduced; the building waste is compacted, and a tight engaged skeleton is formed and is combined with the three-dimensional geogrid cells, so that the bearing capacity of the ground foundation is improved, and the damage due to overlarge deformation of the ground foundation is overcome.

Description

technical field [0001] The invention belongs to the technical field of soft soil foundation reinforcement, and in particular relates to a geocell reinforced sand cushion mixed with construction waste and a construction method. Background technique [0002] Since the tensile strength of the soil is very low, the strength of the soil will be greatly improved by adding a geosynthetic material with a certain tensile strength into the soil. The weak foundation mixed with geotechnical materials can effectively limit the horizontal displacement of foundation soil. The role of geotechnical materials here is to improve the anti-sliding stability of the embankment, increase the limit filling height of the embankment, make the embankment sink evenly, and prevent the embankment from cracking. [0003] Reinforced sand cushion is a kind of soft foundation shallow treatment method. Compared with the deep treatment method with complex construction technology, long construction period and...
