Description
Technical field
It the utility model is related to the buffering antidetonation of Geotechnical Engineering, more particularly to high intensity Zone retaining wall.
Background technology
In high intensity Zone, the use of retaining wall is restricted, in order to meet the requirement of the seismic stability of retaining wall, gear
The size of cob wall is very big, and relatively low using wall height, and these factors seriously constrain its use in high intensity Zone, so as to
Handled using other engineering measures costly, the basic reason for these problems occur is that retaining wall is in highlight lines
In the presence of shake, its structure is unable to buffering energy-absorbing, and huge seismic force directly acts on retaining wall, so as to retaining wall structure size
It is larger, therefore use wall height also critical constraints.Therefore, urgently need a kind of retaining wall antidetonation buffer structure to solve problems,
And promote application of the retaining wall in earthquake territory.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of retaining wall antidetonation buffer structure, to effectively improve gear
The shock resistance of cob wall, the construction investment of retaining wall is saved, expand use range of the retaining wall structure in high intensity Zone.
Technical scheme is used by the utility model solves its technical problem：
A kind of retaining wall antidetonation buffer structure of the present utility model, including retaining wall and the rubble anti-filter for being arranged at its back side
Layer, it is characterized in that：Buffering energy-absorbing layer is provided between retaining wall and the rubble loaded filter；The buffering energy-absorbing layer is by spring knot
Structure, frame structure, permeable geotextiles are formed, and the both ends of spring structure are connected with frame structure, and permeable geotextiles wrap up housing knot
Structure.
The beneficial effects of the utility model are to utilize deformation energy-absorbing function of the buffering energy-absorbing layer under geological process, buffering
To great force caused by retaining wall during geological process, the deformation of buffering energy-absorbing layer is automatic after shake recovers, the suction of buffering energy-absorbing layer
The physical dimension that can reduce retaining wall can be acted on, so as to save the construction investment of retaining wall, it can also be expanded in highlight lines
The use range in earthquake region, the structure has easy for construction, buffering energy-absorbing effect is good, energy-absorbing deformation is automatic to recover, and economic dispatch
Feature, there is wide popularizing application prospect.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is a kind of schematic cross-sectional view of retaining wall antidetonation buffer structure of the utility model.
Fig. 2 is a kind of buffering energy-absorbing Rotating fields schematic diagram of retaining wall antidetonation buffer structure of the utility model.
Component name and corresponding mark are shown in figure：Retaining wall 1, rubble loaded filter 2, buffering energy-absorbing layer 3, spring knot
Structure 31, frame structure 32, permeable geotextiles 33.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, a kind of retaining wall antidetonation buffer structure of the present utility model include retaining wall 1 and are arranged at its back side
Rubble loaded filter 2, buffering energy-absorbing layer 3 is provided between the retaining wall 1 and rubble loaded filter 2.Retaining wall 1 is used as earth-retaining stress
Structure, rubble loaded filter 2 are that the progress of the backer side of buffering energy-absorbing layer 3 is levelling as the anti-filter Rotating fields after the wall of retaining wall 1.Profit
With deformation energy-absorbing function of the buffering energy-absorbing layer 3 under geological process, to huge work caused by retaining wall 1 when buffering geological process
Firmly, the energy-absorbing deformation that buffering energy-absorbing layer 3 occurs after shake can recover automatically, therefore the repetition that can tackle earthquake occurs, buffering
The energy-absorbing function of absorbing energy layer 3 can greatly reduce earthquake and occur to hugely brisance caused by retaining wall 1, so as to effective
The physical dimension of reduction retaining wall 1, therefore the construction investment of the effectively save retaining wall of energy, while it is expanded in high intensity Zone
Use range, in addition buffering energy-absorbing layer 3 also have the anti-filter drain function of retaining wall 1 concurrently.
Reference picture 2, the buffering energy-absorbing layer 3 are made up of spring structure 31, frame structure 32, permeable geotextiles 33, spring
The both ends of structure 31 are connected with frame structure 32, and permeable geotextiles 33 wrap up frame structure 32.The major function of spring structure 31 is
The energy-absorbing buffering that deforms acts on, and it need to do anti-corrosion treatment, and elastic stiffness is analyzed true according to earthquake intensity and its THICKNESS CALCULATION
It is fixed, but rigidity needs to meet that big deformation does not occur when the active earth pressure of retaining wall 1 acts under nominal situation, while must have shake
Elastic deformation auto restore facility afterwards.Frame structure 32 can use etch-proof wire netting or composite geotextile material to make, and it is made
For the fixed frame of spring structure 31, the both ends of spring structure 31 are connected with frame structure 32, so that the stress of spring structure 31
Direction is consistent with horizontal earthquake force direction.Permeable geotextiles 33 are wrapped in the surrounding of frame structure 32, can be to spring knot
Structure 31, frame structure 32 play a protective role, and it needs the loaded filter permeability rate requirement for meeting retaining wall 1.
The advantage of the relatively current technology of this structure is generally to set certain thickness rubble anti-filter after retaining wall at present
Layer, and the permeable composite geotextile material of laying, the main function that rubble loaded filter and earth working material rise is loaded filter drainage,
Although with certain pooling feature, it is extremely limited that it buffers deformation, to the buffer capacity very little of high-intensity earthquake active force,
And it does not have recoverable force ability, therefore retaining wall structure size can not be optimized, expand retaining wall makes in high intensity Zone
Use scope.The utility model proposes structure have that buffering energy-absorbing ability is adjustable, and with deforming automatic recovery capability, Ke Yichong
Geological process power is resisted again.
The size of retaining wall 1 can carry out inspection calculation by the 30-50% values of highest earthquake intensity seismic force.Rubble loaded filter
2 thickness are generally 0.2-0.3m.The spring structure 31 need to do anti-corrosion treatment, and elastic stiffness is according to earthquake intensity and its thickness
Analysis is calculated to determine, but rigidity needs to meet that big deformation does not occur when the active earth pressure of retaining wall 1 acts under nominal situation, together
When must have shake after elastic deformation auto restore facility.Permeable geotextiles 33 should meet the loaded filter permeability rate requirement of retaining wall 1.
Some the of the present utility model principles described above that simply explain through diagrams, are not intended to the utility model being confined to
In shown and described concrete structure and the scope of application, the corresponding modification particularly made to buffering energy-absorbing layer, thus it is every all
The corresponding modification that may be utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
