Description
Technical field
The invention belongs to building machinery technical field, be specifically related to a kind of road surface with soft subgrade and dust treating apparatus.
Background technology
Weak soil refers generally to outward appearance based on grey, and natural void ratio is more than or equal to 1.0, and natural moisture content is greater than the fine grained soils of liquid limit.Comprise mud, mucky soil (Muddy Bottoms cohesive soil silt), peat, cumulosol etc.Mainly, compressibilty high, supporting capacity low mud deposit large by natural moisture content and the soil that a small amount of humus forms.Weak soil refers to the fine grained soils that natural moisture content is high, void ratio is large, compressibilty is high, shear strength is low of strand, lakes and marhshes, valley floor, river shoal deposition.Have that natural moisture content is high, natural void ratio is large, compressibilty is high, shear strength is low, the coefficient of consolidation is little, consolidation time is long, highly sensitive, perturbation large, bad hydraulic permeability, soil layer layered distribution are complicated, the features such as physico-mechanical properties difference is larger between each layer.
Shallow layer soft ground treatment technology has following several: (1) Sand-gravel-cushion Technioue, is generally used for roadbed filling lower ground section, requires that the sedimentation value of in use soft base does not affect expected design object.When arranging bed course, can adopt different materials as the case may be, conventional material has sand or gravel and dirt, also comprehensively can use process with geo-grid, rubble extrusion, Base with Sand Gravel Cushion.(2) cushion, in highway construction, run into water content higher, soft layer is more shallow, and is easy to excavate when being not suitable for material, generally takes to excavate cushion, comprises compressive setting comparatively large, even occurs the soft base that is out of shape and mire area.Process this ground, before excavation, draining protected working will be carried out, the material that is not suitable for excavated out is transported or processed, then back-filling in layers on request, the visual concrete condition sand of backfilling material, gravel, dirt or other appropriate materials.(3) squeeze method, when speedway is half congealed through water, fishpond and the strong mud location of darker mobility, often run into that water content is high, mud compressibilty is large, the soft base of silt clay and Underwater Soft Foundation etc., exclusion method can be adopted process to this kind of soft base.Exclusion method can be divided into two kinds again: one is jackstone exclusion, and another kind is blast exclusion.(5) additive method, when being cohesive soil for top layer, mixes people's additive in the cohesive soil of top layer, improves compression performance and the strength characteristics of ground, to protect the traveling of construction machinery.Also can reach the effect improving banket stable and consolidation simultaneously.Adding material is normally used is quicklime, hydrated lime and cement.Lime adding material is mixed and stirred or plantmix by scene, except reducing soil moisture content, producing except granule effect, As time goes on chemically consolidation can occur, make the change of clay component generation matter to by the soil of consolidation, thus promote soil stabilization.
In additive method, all need to increase additive in weak soil, improve compression performance and the strength characteristics of ground, for additive, some adding materials are normally used is quicklime, hydrated lime and cement.At present, be directed to solid adding material and how mix uniformly with roadbed, be very scabrous problem in engineering construction always.
Summary of the invention
The present invention is directed to above shortcoming, based on solid adding material in solution treatment of soft foundation process how with soft foundation evenly the problem mixed.Propose a kind of road surface with soft subgrade to dust treating apparatus, this equipment mechanism is reasonable in design, drives to squeeze in weak soil carry out material spray by machinery, make solid adding material with soft foundation evenly mix, increase subgrade rating.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of road surface with soft subgrade dusts treating apparatus, and comprise brill tank, be arranged on the stator on described brill tank, it is characterized in that: be movably installed with shower nozzle by securing member above described stator, described shower nozzle top is provided with spray orifice, and conveying pipeline is connected to and bores between tank and shower nozzle; Described brill tank top is provided with air blowing interface and conveying interface, upper cover covers above brill tank, described air blowing interface and conveying interface are provided with chuck, conveying expansion link is by chuck and conveying orifice, air blowing expansion link is by chuck and air blowing orifice, all be connected with joint above described conveying expansion link and air blowing expansion link, swingle is connected with brill tank through upper cover.
Preferentially, described brill pot bottom is also vertically provided with stuff-spraying pipe.
Preferentially, described upper cover surrounding is also provided with hanger.
Preferentially, described conveying pipeline material is metal hose.
Compared with prior art, advantage of the present invention is as follows: driven by machinery and squeeze in weak soil and carry out material spray, by air pressure, solid additive is extruded with soft foundation evenly mix, increase bearing capacity of foundation soil.Mechanism design of the present invention is reasonable, and speed of application is fast, is applicable to promoting the use of.
