Building side, i.e. far field vibration isolation are laid.The vibration wave that railway operation induces is transferred to roadbed by rail, when vibration wave runs into
When of the invention, because the bounce-back of diaphram wall, the Railway Vibration energy of transmission underground wall body is weakened.Then, vibration wave
Transmittance process is constantly consumed energy in air in the cavities, wherein mainly high-frequency vibratory energy is largely dissipated.Afterwards, shake
Dynamic ripple is by continuous reflection, refraction and diffraction between wave resistance block, and in this process, the low-frequency vibration wave energy of vibration wave is by significantly
Degree weakens.Then, partial vibration ripple is transmitted through behind wave resistance block surface, into hollow area, and vibration wave rubs transmission in atmosphere
Further consumed energy.Next, vibration wave is passed through consumes portion of energy by reflection once more during the second wall body.Finally, iron
Road operation induce vibration wave energy by the present invention dissipation effect after, building high-speed railway operation is induced height,
The response of low frequency secondary vibration is greatly suppressed.The present invention is used for railway vibration isolation construction work.

Embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing clear
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to constitute more excellent draw bail.Each technical characteristic in the present invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
Reference picture 1, this is embodiments of the invention, specifically：
The construction method of a kind of diaphragm wall, hollow wave resistance block railway vibration insulation structure, comprises the following steps：
A) in the side of railway, cheated along the groove that railway bearing of trend is excavated out；
B) put on the left and right wall of groove hole and set continuous wall 2, allow wall 2 to be abutted with the wall that groove is cheated so that two
Wall 2 directly forms cavity；
If c) being provided with individual wave resistance group in cavity, if the individual wave resistance group is set along the width interval that groove is cheated, each wave resistance
Group includes the hollow wave resistance block 1 that several cheat spaced pile shape on length direction along groove；
D) groove cheat top covered with top plate so that cavity turn into a closing chamber.
The present invention is arranged on the ground between high-speed railway and building, and should be that is, remote close proximity to building side
Field vibration isolation is laid.The vibration wave that railway operation induces is transferred to roadbed by rail, when vibration wave runs into the present invention, because ground
The bounce-back of lower diaphragm wall, the Railway Vibration energy of transmission underground wall body is weakened.Then, wave energy air in the cavities is vibrated
Middle transmittance process is constantly consumed, wherein mainly high-frequency vibratory energy is largely dissipated.Afterwards, vibration wave is between wave resistance block
By continuous reflection, refraction and diffraction, in this process, the low-frequency vibration wave energy of vibration wave is significantly weakened.Then, part
Vibration wave is transmitted through behind wave resistance block surface, into the hollow area of wave resistance block, and the vibration wave transmission that rubs in atmosphere further disappears
Energy consumption.Next, vibration wave is passed through consumes portion of energy by reflection once more during the second wall body.Finally, railway operation is lured
After dissipation effect of the vibration wave energy of hair by the present invention, the high and low frequency that building is induced high-speed railway operation is secondary
Vibratory response is greatly suppressed.
The section of the wave resistance block 1 of the present embodiment is circle, and this can allow vibration wave to be encountered after wave resistance block 1, its direction of propagation
It is more complicated, vibration isolating effect can be improved.
Wave resistance block 1 in same wave resistance group has one kind in the steel pipe or concrete reinforced pipe of sealing using two ends
Steel pipe of the two ends with sealing, two in concrete reinforced pipe are respectively adopted in wave resistance block 1 in structure, or same wave resistance group
Plant structure.Steel pipe easily transmits dither ripple, while having good reflex to low-frequency vibration ripple, coordinates steel duct
Hollow part just can well simultaneously to high and low frequency secondary vibration response suppress.
In order to improve effectiveness in vibration suppression, increase its order of reflection and reflection space, including three wave resistance groups, same wave resistance group
The line of the cross-section centroid of interior wave resistance block 1 is wave resistance line, and the distance of the wave resistance line of wall 2 and side is a, adjacent wave resistance line
Distance be b, a：B=3:4.Make a smaller, allow vibration to enter as early as possible, vibration damping is then realized by adjacent wave resistance group, it is such
Set, can also allow the present invention width try one's best it is small.
In order to make vibration interreflection, increase reflective distance in two adjacent wave resistance groups adjacent to consume its energy
Two wave resistance groups shift to install.
In order to be able to obtain enough vibration isolating effects, the width of cavity is 1~2m.
Because the ground of railway is deeper, and ground is often easily transmitted vibration, and the depth of cavity is 5~10m.So,
Even if the vibration of ground can bypass the present invention, it is also desirable to by very long propagation distance, and will be by during propagation
Consumed energy.
Step b) the walls 2 include the prefabricated wall element of multiple interconnections laid along the wall that groove is cheated, many
Individual wall element is put into cavity by repeatedly lifting, and the wall element in same wall 2 is adjacent to be set.
Suddenly b) in wall 2 lower end stretched into the mode beaten of pressure groove hole at least 1 meter of bottom depth, in step b)
Wave resistance block 1 is first first to be drilled in pit bottom, the depth at least 1 meter of bottom for then again cheating the insertion groove of wave resistance block 1.So not
Reinforced with other, connector can just realize safe fixation.
Step c1 is additionally provided between step c) and step d))：On the bottom that groove is cheated base is laid to mortar concrete
Bottom., cavity internal water accumulation can be so prevented, causes groove to cheat the softening of bottom ponding.
The better embodiment to the present invention is illustrated above, but the present invention is not limited to the embodiment,
Those skilled in the art can also make a variety of equivalent modifications or replacement on the premise of without prejudice to spirit of the invention, this
Equivalent modification or replacement are all contained in the application claim limited range a bit.
