Description
Technical field
The utility model is related to subgrade engineering reinforcement technique fields, particularly a kind of drilling drilling tool for carrying soil filling device.
Background technology
At present, domestic many existing railways can not meet the needs of passenger-cargo surge, it is necessary to which Speed Increased Reformed, this just holds roadbed
It carries power and proposes higher requirement.Existing railway originally is generally filled using silty clay soil, and the lime that surface layer employs 20cm changes
Good layer, but the silty clay soil under layer is improved due to water logging and the influence of dynamic load, minimum requirements of the bearing capacity well below 150kPa,
Therefore need to carry out consolidation process to roadbed.
Existing subgrade strengthening is frequently with cement-soil compaction pile mode, i.e.,：Firstly the need of between two sleepers base course drill out
The drilling of multiple a diameter of 24cm, then layering rams and fills out soil cement filler, using in the high intensity and formation of pile of soil cement
Crowd in-out effects achieve the purpose that improve subgrade bed bearing capacity.During such mode is implemented, drilling is one more important
Operation link, success or failure directly affect the consolidation effect of roadbed.Currently used bore mode have the drilling of artificial Luoyang Spade and
Spiral card punch pore-forming two ways.1) manually Luoyang Spade pore-forming is manually to lift Luoyang Spade, boring extracting soil is poured, then soil
Secondary Shocks fetch earth again after removal, are constantly recycled to regulation hole depth.This method there are the shortcomings that, first, Luoyang Spade active area is big,
Own wt is limited, for there is the roadbed of improvement layer, can not penetrate improvement layer, it is necessary to which the drill rod instrument for coordinating weight big is worn
Saturating operation；Second is that worker's amount of labour is big, it is usually the point operation of evening skylight due to reinforcing, worker is easily tired, causes drilling matter
Amount is low；Third, low construction efficiency, one hour of two people is only capable of into a hole, if uninterrupted working time is long, pore-forming
Time may further increase.2) spiral card punch pore-forming is using motor-driven auger bore, which bores soft soil horizon
Hole efficiency is higher, but since its drill bit helical blade is big, above active force it is small, often skid, can not wear in improvement layer construction
Saturating roadbed improvement layer is, it is necessary to which the drill rod for coordinating weight big abolishes improvement layer to construct；And the dregs drilled out is deposited directly on
On bed, railway roadbed can be polluted, railway roadbed is made to lose effect, increase economic input.
In addition, the daily Window time of construction of railways is generally three hours, the construction time is shorter, will if efficiency is low
Delay the duration, harmful effect is caused to operation.
Utility model content
