Abstract
The invention relates to an isolation trench which solves the problem that the traditional internally hollow isolation trench cannot be arranged under roads for the reason that the internally hollow isolation trench cannot bear loads. According to the isolation trench, a trench body with a trapezoidal section wide at top and narrow at bottom is arranged in a roadbed pure soil layer in a digging manner; polystyrene plates and reinforced concrete plates are paved in the skew walls on two sides of the trench body from upper part to lower part in sequence; a gravel filling layer flushing with the trench opening is in the trench body; a concrete road surface is poured above the gravel filling layer which is regarded as a base. The isolation trench disclosed by the invention is filled by gravels, so that the isolation trench has the load bearing capacity, and can be arranged under roads. Meanwhile, a vibration isolation tank is arranged in the gravel filling layer, so that transmitted vibration waves can be effectively adsorbed, and the transmission of the vibration waves on two sides of the isolation trench is further reduced.
Description
Technical field
The invention belongs to building vibration isolation technique field, relate to a kind of vibration isolate ditch be arranged on below road.
Background technology
Vibration isolate ditch is a kind of common engineering method, in order to hinder or to change peripheral vibration wave to the propagation by blind zone, thus reduces the ground vibration of blind zone.The principle of vibration isolate ditch is based upon on the basis of wave reflection, scattering.When propagate in ripple run into the interface of two kinds of different elastic fluids time, a part of incidence wave is reflected back the first medium, another part wave loops in the second medium, Here it is elasticity wave reflection and transmission phenomenon.Vibration isolate ditch can also change wave frequency distribution, the energy of the main frequency range of dispersive wave, is conducive to the dither effect reducing vibration.Because vibration wave is when underground runs into different medium, between medium, difference is larger, and vibrometer ground roll more easily reflects and not easily passes dielectric interface.For stoping surperficial wave propagation, the measure cutting off Vibration propagation approach can be taked, namely take ditching form on stratum.Be empty in the vibration isolate ditch ditch of common buildings, i.e. not packing material, then cover plate is set at vibration isolate ditch top, as the CN203531169U patent of Patent Office of the People's Republic of China's bulletin on April 9th, 2014, name is called that, from displacement shock insulation trench system, the ditch body inside of this structure of vibration isolation ditch is empty, above establishes cover plate, the heavy ability of cover plate, therefore the vibration isolate ditch of this structure can not be arranged on below road.
Summary of the invention
The object of the invention is to solve vibration isolate ditch empty in tradition cannot load-bearing, cannot be arranged on problem below road, provide a kind of vibration isolate ditch arranging the band below road and fill.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vibration isolate ditch, the ditch body of trapezoid cross section wide at the top and narrow at the bottom is dug at roadbed element soil layer, skew wall in ditch body both sides lays polyphenyl plate and armored concrete slab from down to up successively, be the sandstone packed layer concordant with the exit or entrance of a clitch in ditch body, water up based on sandstone packed layer and establish rigid pavement.This programme vibration isolate ditch position is road, so need carry out backfill process to vibration isolate ditch.According to the vibration isolate ditch mechanism of action, respectively arrange one deck armored concrete slab and polyphenyl plate at both sides furrow bank, middle filling sand, utilizes armored concrete slab and these two kinds of distinct materials of polyphenyl plate to carry out usable reflection to vibration wave thus reduces dither effect.Rigid pavement width is greater than the width of ditch body.
As preferably, described ditch body both sides skew wall and horizontal plane angle are 45 ~ 60 degree.Different according to soil property, select reasonably to pile angle of slope.
As preferably, described polyphenyl plate thickness is 40mm, and described steel concrete plate thickness is 100mm.
As preferably, in described sandstone packed layer, be provided with the vibration isolation water tank extended along ditch body direction, be provided with the dividing plate extended along ditch body direction in vibration isolation water tank, dividing plate evenly offers vibration damping hole.Vibration isolation water tank utilizes the vibration wave of the absorption of vibrations transmission of water body, eliminates vibration wave energy, damping vibration wave loops.Back and forth through the vibration damping hole on dividing plate when shaking about water body, the retardance of vibration damping hole to water body is utilized to cut down vibrational energy rapidly.
As preferably, the bottom of described vibration isolation water tank is placed on the bottom of ditch body, and vibration isolation tank top is no more than sandstone packed layer end face.
As there being choosing, described dividing plate is dull and stereotyped.
As other preferred, described dividing plate is waveform plate along ditch body direction, and two ends and the water tank sidewall weld of dividing plate are fixed, can be freely movable between the upper and lower side of dividing plate and water tank wall.Be ripple struction between dividing plate two fixed end, and upper and lower sides is free side, and dividing plate itself can be made can to absorb certain vibrational energy, reduces vibration intensity of wave.
As preferably, be arranged in parallel in described vibration isolation water tank multilayer insulating panel, and the vibration damping hole site of adjacent separator shifts to install.The concussion position of water body between two dividing plate vibration damping holes interlocks, and forms complicated shear action, can more effectively absorbing vibrational energy.
As preferably, described vibration isolation tank box top is provided with water inlet, and water inlet is communicated with rainwater on road surface mouth.Rainwater is utilized to supplement water in vibration isolation water tank.
As preferably, described vibration isolation water tank is along ditch body bearing of trend subsection setup.Vibration isolation water tank can be arranged in split, reduces difficulty of processing.
Vibration isolate ditch of the present invention adopts sandstone to fill, and makes vibration isolate ditch have weight capacity, can be arranged on below road; Vibration isolation water tank is set in sandstone packed layer, effectively can absorbs the vibration wave of transmission, reduce the transmission of vibration isolate ditch both sides vibration wave further.
