Description
Technical field
The invention belongs to municipal construction fields, are related to a kind of road construction method, in particular to a kind of steelframe geotechnique frame generation
The construction method of dirt road base is used for for block stone.
Background technique
Roadbed is the basis on track or road surface, is the earthen structure by excavating or filling and formed.The master of roadbed
Act on be for track or road surfacing and train or driving operation necessary condition is provided, and bear track and rolling stock or
The dead load and dynamic load of person road surface and traffic loading, while load being transmitted and being spread to ground depths.In civil engineering,
Roadbed is all occupied an important position in construction quantity, occupied area and investing.Roadbed is different according to the orographic condition locating for it, has
Two kinds of citation forms: embankment and cutting are commonly called as embankment and excavation.The material for building roadbed, no matter filling out or digging, mainly native stone class
Discrete material is often subject to the variation of the natural conditions such as geology, water, rainfall, weather, earthquake so roadbed is a kind of earth structure
Invasion and destruction, resistivity is poor.Sub-surface is with homogenous material on roadbed (or bed course) surface according to certain skill
The quality of layer structure made of art measure layering making, material and quality directly affects the quality and service performance on road surface.
Base is the supporting course of entire road.Play a part of to stablize road surface.In practical projects, either filled-up ground or excavation
Roadbed can all use block stone or cement stabilized soil etc. and be frequently encountered and roll not in whole process of deployment as roadbase
Sufficiently, the problems such as stability is insufficient, this also gives the road after entirely building up to bring hidden danger, and later period roadbed subsidence, flatness are not
The problems such as enough, is quite serious.
Summary of the invention
It is an object of the invention to solve existing dirt road base to use block stone or cement stabilized soil etc. as roadbase, in entirety
It in process of deployment, is frequently encountered and rolls the problems such as insufficient, stability is insufficient, cause later period roadbed subsidence, flatness inadequate
The problem of, a kind of construction method that steelframe geotechnique frame replaces block stone to be used for dirt road base is provided, steelframe geotechnique frame and geotechnological lattice are passed through

The following steps are included:
Step 1 excavates roadbed foundation trench, forbids phenomenon of backbreaking in digging process, guarantee the flatness and levelness of excavation face；
Step 2, making lower layer TGXG makees reinforcement processing in the banketing of compacting after the compacting of roadbed foundation trench bottom surface, enables
It is enough to become entirety in the cohesive strength that lacing wire direction obtains and the tensile strength of lacing wire is adaptable, become one can support it is outer
The composite construction of power self weight；
Step 3, by prefabricated steelframe geotechnique's frame proper alignment on roadbed, it is ensured that adjacent steel bar framework fits closely, simultaneously
Guarantee flatness and levelness；
It is real to fill soil pressure in steelframe geotechnique's frame for step 4, it is ensured that each framework compacting is abundant, uniform force；
Step 5 is laid with single layer multilayer steelframe geotechnique frame or repeats Step 3: four are laid with multilayer steelframe geotechnique's frame, in top layer
Making topsoil work grid on steelframe geotechnique's frame forms a whole composite construction with lower layer's grid collective effect；
Step 6 pours lightweight concrete base；
Step 7, casting concrete surface layer/asphalt surface course.
This method replaces block stone using prefabricated steelframe geotechnique's frame, and the steel bar framework of steelframe geotechnique's frame can provide better branch
Support effect, improves roadbed bearing capacity, reduces roadbed subsidence.Compared to the existing simple form of construction work using soil engineering bag, we
The steel bar framework of method not only acts as supporting role, and confines to soil engineering bag and banketing, when avoiding using soil engineering bag merely,
Soil engineering bag breakage flowing of banketing causes roadbed irregular, and pit etc. is generated under long term, causes surface evenness to be deteriorated, influences to hand over
Logical safety.
Preferably, in step 3, the adjacent steel bar framework fissure of displacement cloth before and after road direction of same layer steelframe geotechnique's frame
It sets.
Preferably, repeat Step 3: four be laid with multilayer steelframe geotechnique's frame when, the reinforcing bar of neighbouring layer steelframe geotechnique's frame
Frame or so layout of the wrong seam.
Preferably, repeat Step 3: four be laid with multilayer steelframe geotechnique's frame when, the reinforcing bar of neighbouring layer steelframe geotechnique's frame
Layout of the wrong seam before and after frame.
Preferably, first calculating the amount of fill of each steelframe geotechnique frame, addition first artificial preliminary bat after banketing in step 4
It is real, then practical road roller compacting.
Preferably, the length and width of the steelframe geotechnique frame is 0.8-1.2m, and it is highly 0.4-0.6m, the steelframe
The steel bar framework of geotechnological frame selects the molding of diameter 6mm reinforcement welding.
