Abstract
The utility model discloses a building rubbish road bed course structure, including the four layers, from top to bottom be in proper order: road road surface structural layer, dust improvement layer, building rubbish bed course and soil matrix layer. Using building rubbish road bed course to substitute the blotter, satisfying road surface structure and road bed strength requirement, the outward transport of effectual reduction building rubbish reduces construction cost.
Description
Technical field
The utility model relates to a kind of building waste road cushion structure.
Background technology
Building waste refer to build and demolition of buildings process in the discarded object that produces.Along with the quickening of China's urbanization, industrialization development speed, urban construction develops simultaneously from extensional mode exploitation with extensive reconstruction of the old city town, the reorganization and expansion of residential quarters scale construction and road, causes a large amount of building waste sharply to produce.These building wastes overwhelming majority, without any process, is just transported to countryside air storage or landfill, not only causes the refuse collection cost of great number, occupy a large amount of soil, and the omission, dust, dust and sand etc. of clearing and producing in stacking cause environment pollution again.
Therefore, gather materials on the spot, study novel building waste road cushion, for saving, intensive use resource, preserve the ecological environment, reduce road foundation process construction costs, have important practical significance.
Summary of the invention
For solving prior art above shortcomings, the invention provides a kind of building waste road cushion structure, substituting hardcore bed with building waste, meeting road structure and subgrade strength requirement, the effective building waste that reduces is transported outward, and reduces construction cost.
For achieving the above object, the present invention adopts following technical scheme:
A kind of building waste road cushion structure, comprises four layers, is from top to bottom followed successively by: the improvement of road surface structure layer, dirt layer, building waste bed course and soil matrix.
Described building waste road cushion structure is applicable to filled-up ground, cut subgrade or fish pond and irrigation canals and ditches roadbed.
Described building waste is become by concrete block, masonry and local soil type.
The maximum particle diameter of described building waste is not more than 400mm.
The thickness of described road surface structure layer is 50-70cm, and the thickness of described dirt improvement layer is 20-30cm.
When described building waste road cushion structure is used for filled-up ground, the top of described building waste bed course is provided with the building waste transition zone that thickness is 250-400mm, the maximum particle diameter of described building waste transition zone is less than 15 centimetres, and the fine granules content being less than 0.05mm is not less than 30%.
When described building waste road cushion structure is cut subgrade, the thickness of described building waste bed course is 30-60cm.
When described building waste road cushion structure is filled-up ground, or fish pond and irrigation canals and ditches roadbed time, all filled by described building waste bed course between described dirt improvement layer and soil matrix.
The beneficial effects of the utility model are:
Use building waste road cushion to substitute hardcore bed, meet road structure and subgrade strength requirement, the effective building waste that reduces is transported outward, and reduces construction cost; Building waste transition zone can effectively improve bed course resistance to overturning and subgrade strength.
Building waste is made up of inorganic matter classes such as gravel-concrete, brickbat watt and broken sandy and stony soils.Its chemical composition is silicate, oxide, hydroxide, carbonate, sulfide and sulfate etc.It has goodish intensity, hardness, abrasion resistance, impact toughness, frost resistance and water resistance etc., i.e. high, the good stability of intensity.Building waste has again goodish physics and chemistry stability, and its performance is better than clay, silty soil, even sand and rendzinas.
Building waste good water permeability, meets water not freezing up, does not shrink, and is the constructional materials that water stability that highway construction is rare is good.Building waste particle is large, and specific area is little, few containing film water, does not possess plasticity.Good water permeability can block capillary water and rise, and under dampness and environment, the foundation pad of building waste, Strength Changes is little, is that desirable intensity is high, the Load materials of good stability.
Accompanying drawing explanation
Fig. 1 is building waste road cushion schematic diagram of the present utility model;
Wherein, 1. road surface structure layer, 2. dirt improvement layer, 3. building waste bed course, 4. soil matrix.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Material requirements:
(1) building waste mainly becomes with concrete block, masonry and local soil type, the debris such as household garbage of must not adulterating and branch weeds.
(2) the maximum particle diameter principle of building waste should not be greater than 400mm.
Construction and technical requirements
The thickness of road surface structure layer is 50-70cm, and the thickness of described dirt improvement layer is 20-30cm.
(1) filled-up ground
When building waste is used for filled-up ground, compaction quality control criterion is with reference to " highway subgrade design specifications " (JTGD30-2004) 3.8.3 bar soft building stones compaction quality control criterion.
Building waste roadbed treatment and dirt are improved between layer and are arranged building waste transition zone, thickness 250 ~ 400mm, and transition zone maximum particle diameter should be less than 15 centimetres, and the fine granules content being wherein less than 0.05mm should not be less than 30%.
(2) cut subgrade
Cut subgrade, groundwater table is too high or soil property is poor, need roadbed treatment and change when filling out to adopt building waste, compaction quality control criterion is with reference to " highway subgrade design specifications " (JTGD30-2004) 3.8.3 bar soft building stones compaction quality control criterion.The thickness of the building waste bed course of cut subgrade is 30-60cm.
(3) fish pond and irrigation canals and ditches roadbed treatment
When fish pond and irrigation canals and ditches roadbed treatment, building waste is first adopted to carry out squeezing silt and backfill.
As shown in Figure 1, a kind of building waste road cushion application, comprises road surface structure 1, dirt improvement layer 2, building waste bed course 3 and soil matrix 4 from top to bottom successively; Wherein, dirt improvement layer is 6% dirt improvement, and the thickness of road structure is 64cm; The thickness of 6% dirt improvement is 20cm; The thickness of building waste bed course is 30cm.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
