Description
Technical field
The utility model relates to a kind of improved device of subgrade soils, and particularly relating to is a kind of highway subgrade improvement construction equipment.
Background technology
The surface layer of subgrade bed of roadbed is often called as bearing bed or the bearing stratum of roadbed, is the part of directly bearing car load.It is the important component part of roadbed design, and also for the roadbed of its lower floor provides protection, therefore surface layer of subgrade bed must have enough strength and stiffness, also will have stability and durability.Part construction section, because not meeting roadbed design specification, needs to adopt artificial modified soil, especially speedway.Along with large-scale load-carrying vehicle quantity increases, the speed of a motor vehicle is accelerated, and highway needs the time interval of maintenance more and more short.No matter be building or later period maintenance, a kind of requisite method by the soil property of improvement roadbed bearing bed, such as mix the aggregates such as cement, lime and flyash, and improve by lime the lime stabilized soil that some clay, expansive soils etc. obtain, certain resistance to compression and tensile strength can be improved, there is good water stablize and freezing stability, and economical and practical, roadbed topsoil can be widely used in.
Chinese invention patent ZL200810048912.0 relates to a kind of method utilizing steel slag to fill highway subgrade, the steps include: that (1) adopts steel slag filling roadbed; (2) the filling roadbed fill core concrete of slag need be controlled, ensure the stability of roadbed; (3) slag railway embankment using should adopt vibratory roller layered rolling; when rolling, slag should be within the scope of optimum moisture content; adopt the method for test section test to determine suitable to roll facility, adopt maximum dry density and optimum moisture content to calculate standard as the degree of compaction that slag is filling roadbed; (4) cross-sectional design of steel slag filled-up road embankment, comprises depth of fill, side slope of embankment ratio of slope, fills thickness, closedtop layer, underseal layer, interlayer, bank protection and drainage system.
This patented method is easy, easy to operate, decreases stacking place and the environment pollution of slag; turn waste into wealth, facilitate environmental protection, solve the not enough problem of highway engineering filler; cost is low, and the quality of its roadbed filled out can meet the construction requirement of High-Grade Highway Subgrade.
Said method is comparatively large to steel scrap metal material demand, and at present for the process of soft base, is mostly to adopt piling prepressing and vacuum method, and these two kinds of method process roadbeds are that the time is long, and speed is slow, and the earthwork building stones simultaneously needed are also many.Therefore, to the method being modified to another raising bearing capacity of subgrade soils, be all adopt grouting to carry out soft soil foundation at present, this method speed is slow, and cost is high, simultaneously the construction technology also more complicated of its device.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of highway subgrade improvement construction equipment, the utility model, by rational structure design, makes device can send in roadbed by aggregate fast when constructing, mix with roadbed, achieve good treatment effect.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of highway subgrade improvement construction equipment, comprise cylinder, it is characterized in that, described cylinder is divided into material spray room and is located at the motor room below described material spray room, and be provided with stepper motor in described motor room, taper bit is connected to below stepper motor; The sidewall of described material spray indoor is laid with the discharge tube under being tilted to, main slurry pipe is arranged on material spray indoor, uniformly above it is connected with shotcrete pipe; Be connected with slip casting interface above described main slurry pipe, above material spray room, be connected with material feeding interface.
Preferentially, described material spray indoor are also provided with cable protection pipe, and supply line is connected with stepper motor through described cable protection pipe.
Preferentially, little drill bit is also connected with above described taper bit.Little drill bit quantity is four, is 90 degree between any two and is arranged on taper bit surrounding.
Preferentially, also comprise the button block for connecting fluid cylinder pressure, described button block is arranged on cylinder top.
The beneficial effects of the utility model are: the utility model is driven by draw-gear and moves on roadbed, to be sent in roadbed by device by the lifting of hydraulic cylinder and carry out material spray, speed is fast, and treatment effect is good, construction technology is simple, and the bearing capacity of ground is strengthened.
