Description
Technical field
The present invention relates to a kind of railway and subtract vibration insulation structure, be specifically related to a kind of railway being arranged between railroad track and building and subtract vibration insulation structure continuously.
Background technology
Railway transportation effectively improves traffic environment, facilitates people's trip, has driven town and country construction and economic development, had significant economic benefit and social benefit.But being as high-speed railway, the developing rapidly of heavy haul railway, the continuous acceleration of urbanization scale, the vibration that railway transportation causes also brings some negative effects to urban and rural environment.On the one hand, the serious vibration of excess have impact on passenger and the orthobiosis of Along Railway people；On the other hand, vibration also can cause the fatigue damage of device structure and surrounding building.And along with living standard requirement is improved constantly by people, the adverse effect that Railway Vibration brings highlights day by day, and the protection of track Along Traffic Trunk Lines environment is constantly promoted by governments at all levels.
Therefore, take to subtract accordingly vibration isolation measure in rail track periphery adjacent domain, reduce the adverse effect that railway operation causes, it has also become a key issue faced by having in railway construction.For the vibration of railway transportation, mainly control three broad aspect be controlled from vibration source control, Vibration propagation control and building self.For the rail track built up and building, control Vibration propagation and just become a kind of particularly important means.
Traditional control Vibration propagation subtract in vibration isolation measure, empty ditch to subtract vibration isolating effect best, but it is affected by soil body self stability, applies the degree of depth the most shallower, it is impossible to reaches preferable vibration isolating effect, limits the popularization and application in Practical Project of the sky ditch.Traditional ditch of filling is typically to fill the material such as concrete or foam plastics of single in empty ditch, tamps, centre does not interspaces；Although so can ensure that the depth requirements of vibration isolation barrier, but cost is the highest, and vibration isolating effect is not as good as empty ditch.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of railway subtracts vibration insulation structure continuously.
The present invention solves that this problem is adopted the technical scheme that:
The railway of the present invention subtracts vibration insulation structure continuously, and its agent structure, for filling ditch, is provided with continuous compact arranged hollow cylinder in filling ditch, is provided with obturator between outer wall and the filling ditch inwall of hollow cylinder.
Described hollow cylinder is double-wall corrugated pipe.
Described obturator is EPS particle cement soil mixing inserts.
The present invention has the advantage that with good effect:
The railway of the present invention subtracts vibration insulation structure continuously, arranges the most closely double-wall corrugated pipe filling in ditch, and arranges obturator at double-wall corrugated pipe and the hole filled between ditch, it is ensured that subtract vibration insulation structure stability, be conducive to increasing the projected depth of vibration insulation structure.Obturator uses the EPS particle cement soil mixing inserts of lightweight, on the one hand protects the structural stability of double-wall corrugated pipe self, on the other hand improves the wave impedance ratio between different medium, improves vibration isolating effect.The vibration insulation structure that subtracts of the present invention is arranged between vibration source and protected structure, forms medium variation band, effectively stop vibration to the propagation of protected structure its subtract that vibration isolating effect is notable, speed of application is fast, pollution-free, cheap, durable in use.

Detailed description of the invention
Referring to the drawings and specific embodiment subtracts vibration insulation structure continuously to the railway of the present invention and is described further.Following each embodiment is merely to illustrate the present invention and not limitation of the present invention.
The invention provides a kind of railway and subtract vibration insulation structure continuously, this structure is to arrange double-wall corrugated pipe in filling ditch, double-wall corrugated pipe uses EPS particle cement soil mixing inserts with filling between ditch, formation one is effectively continuous subtracts vibration insulation structure, and its detailed description of the invention is as follows.
Fig. 1 is the structural representation that the railway of the present invention subtracts vibration insulation structure continuously；Fig. 2 is the sectional view of line A-A along Fig. 1.As depicted in figs. 1 and 2, the railway of the present invention subtracts vibration insulation structure continuously, and its agent structure, for filling ditch 1, is provided with continuous compact arranged hollow cylinder 3 in filling ditch 1, is provided with obturator 2 between outer wall and filling ditch 1 inwall of hollow cylinder 3.
Hollow cylinder is double-wall corrugated pipe, and the inner and outer wall of double-wall corrugated pipe has annular corrugated structure, greatly strengthen the ring stiffness of tubing, thus enhances the pipeline resistance to soil load, improves the stability of empty well structure.Under conditions of waiting load, double-wall corrugated pipe has only to relatively thin tube wall just can meet requirement.Therefore, compared with real wall pipe mutually, the raw material about half can be saved, so the cost of double-wall corrugated pipe is relatively low.And, double-wall corrugated pipe lightweight, to carry and connect all very convenient, quick construction, maintenance work is simple, is more suitable for the situation that the duration is tight and execution conditions are poor.
Obturator is the EPS particle cement soil mixing inserts that the natural impedance with surrounding soil and double-wall corrugated pipe differs greatly.EPS(Expanded Polystyrene, expanded polystyrene (EPS)) particle cement soil mixing inserts is to add after EPS granule, curing materials and water mix and blend the lightweight earth working material through solidifying to form in the feed.The raw material soil of EPS beads-mixed lightweight soil can be drawn materials because of ground, mud, sand and clay；Curing materials is cement；EPS granule is expanded polystyrene (EPS) spherolite or waste plastic foam crushed particles.EPS beads-mixed lightweight soil has that density is little, intensity is high, the advantage of intensity scalable, good economy performance.On-the-spot use casting and constructing, first raw material soil, EPS granule, curing materials and water be mixed into the slurry with mobility, then with pump as power supplying apparatus, with pipeline for medium by slurry pipeline steel to job site, carry out casting and constructing, easy construction is quick.
The present invention is filling in ditch the most closely double-wall corrugated pipe, and arranges obturator at double-wall corrugated pipe and the hole filled between ditch, it is ensured that originally subtract vibration insulation structure stability, be conducive to increasing the projected depth of vibration insulation structure.Obturator uses the EPS particle cement soil mixing inserts of lightweight, on the one hand protects the structural stability of double-wall corrugated pipe self, on the other hand improves the wave impedance ratio between different medium, improves vibration isolating effect.
Its concrete work progress is as follows: excavating filling ditch 1 to the designated depth of wide 600mm, mud off guarantees the stability of groove, the most closely puts into the double-wall corrugated pipe of diameter 315mm along groove center line, and fixes with support.Double-wall corrugated pipe uses lifting method down tube, with threaded between pipe.EPS particle cement soil mixing inserts is inserted in the gap filled between ditch inwall and double-wall corrugated pipe outer wall.
The present invention is arranged between vibration source and protected structure, forms a medium variation band, effectively stops the vibration propagation to protected structure.The railway of the present invention subtract continuously vibration insulation structure subtract that vibration isolating effect is notable, speed of application is fast, pollution-free, cheap, durable in use.
