Description
Technical field
The present invention relates to high-speed railway subgrade technical field of construction, more particularly to vibrated roller intelligence frequency modulation
Amplitude modulation rolling method.
Background technique
It needs to carry out a large amount of earth material or gravel embankment in railway engineering and highway engineering construction, due to earth and stone material
Filling construction proportion is larger, thus, the construction method and quality of native stone reclamation work directly affect the quality of corresponding engineering
And cost.Especially high-speed railway, it is desirable that subgrade stability it is stronger, it is thus, tighter to construction method and quality requirement.
Currently, the filler that roadbed filling construction is used includes: A group-high quality filler, including lump stone, gradation is well and thin
The native content of grain is less than 15% erratic boulder soil, land pebble, gravelly soil, circle gravel soil, dust soil, gravelly sand, coarse sand, middle sand.
B group-is well gathered materials.Including dysgeogenous magma stone (cement is siliceous or calcareous), the erratic boulder of disproportionately graded
Soil, land pebble, gravelly soil, circle gravel soil, dust soil, gravelly sand, coarse sand, middle sand, fine grained soil content 15%~30% erratic boulder it is native,
Land pebble, gravelly soil, circle gravel soil, dust soil and fine sand, glutinous sand, emery dust soil, sand clay.
C group-general filler.Magma stone (cement is shale) including easy-weathering, fine grained soil content is 30% or more
Erratic boulder soil, land pebble, gravelly soil, circle gravel soil, dust soil and flour sand, silt, glutinous silt.D group-poor matter filler not easy to use.
Including severely-weathered and completely decomposed magma stone, glutinous silt and clay.
E group-forbid using filler inferior, including organoclay.
Roadbed filling construction generallys use layering, pave smooth, watering or sunning, cal rolling (road roller), examines label
The construction technology process such as card, road surface and side slope shaping are constructed, but in current cal rolling construction, often manual control
Rolling compaction machine is rolled, and Subgrade Compaction Quality includes compaction, is compacted the interior of three aspect such as uniformity and compaction stability
Hold.Compaction is exactly that roadbed rolls degree；Compacting uniformity refers to the uniform distribution of forces of road bed mechanical property；Compacting
Stability is the degree of stability of road bed mechanical property.
Detection & Controling for roadbed filling engineering compaction quality, using conventional " point type " sampling Detection method, i.e.,
After every layer is completed to roll, random selecting point, sampling Detection.Using conventional " point type " sampling Detection method, can not remember in real time
Record and inspection field compaction situation, and working efficiency is low.
Currently, during for the compacting operation of high-speed railway subgrade, what most process still required manual intervention,
It cannot achieve intelligent automatic running, manipulation road roller progress roadbed driven by operating personnel and is rolled, and roadbed is rolled
It carries out repeating to roll according to fixed mode, but needs to roll ginseng to roadbed often due to filler is different in practice of construction
Number is adaptively adjusted；And it is also different to corresponding Optimized Lamination Parameter that filler difference, which rolls the stage, in practice of construction
, still, there is no one kind to carry out intelligent frequency modulation tune for different fillers and filler different phase in the art
The road roller and rolling method of width.
Therefore, on the basis of the compaction state locating for detection filler automatically, optimal vibration that intelligent decision should currently use
Dynamic frequency, vibration amplitude and guide road roller to carry out the vibrated roller intelligence that automatic frequency-conversion luffing is constructed by optimized parameter
