Description
Technical field
Geotechnical Engineering is the utility model is related to, the pile foundation cantilever barricade closing slope knot being more particularly to arranged on soft soil foundation
Structure.
Background technology
The foundation soil embankment closing slope that pile foundation cantilever barrier wall structure is applied to be also easy to produce differential settlement is reinforced, but when its setting
In soft soil foundation particularly weak soil thicker ground or higher barricade, the horizontal distortion of pile foundation cantilever barricade may be larger,
And the resistance to overturning of structure may be influenced whether.It is therefore proposed that a kind of pile foundation cantilever barrier wall structure suitable for soft soil foundation
It is significant.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of soft soil foundation pile foundation cantilever barrier wall structure, makes effectively
The horizontal distortion of pile foundation cantilever barricade is controlled, and it is easy for construction.
Technical scheme is as follows used by the utility model solves above technical problem：
A kind of soft soil foundation pile foundation cantilever barrier wall structure of the present utility model, it is characterized in that it includes：Pile foundation and cantilever gear
Wall, pile foundation are in a row disposed in firm ground through soft soil foundation, and cantilever dams setting is at the top of pile foundation and fixed thereto
Connection；Reinforcing pile and cushion layer structure, reinforcing pile are disposed in the soft soil foundation on the inside of cantilever barricade, and cushion layer structure is arranged on
On the composite foundation that reinforcing pile is formed；Embedded bar, is arranged on the inner side of cantilever barricade bottom plate, and with geotechnological lattice in cushion layer structure
Grid tense connection；Roadbed filling body, placement in layers is on the inside of cushion layer structure and cantilever barricade.
The beneficial effects of the utility model are that to efficiently solve pile foundation cantilever barricade horizontal distortion on soft soil foundation larger
Problem, and have the characteristics that easy for construction, economical and environmentally friendly, there is popularizing application prospect.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is a kind of sectional schematic diagram of soft soil foundation pile foundation cantilever barrier wall structure of the utility model.
Fig. 2 is a kind of local drawing of soft soil foundation pile foundation cantilever barrier wall structure of the utility model.
Component name and corresponding mark are shown in figure：Pile foundation 1, cantilever barricade 2, reinforcing pile 3, cushion layer structure 4, under it is broken
Rock layers 41, medium stone layer 42, upper metalling 43, lower GSZ 44, lower GSZ 45, embedded bar 5, roadbed filling body 6,
Soft soil foundation A.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Reference picture 1, Fig. 2, a kind of soft soil foundation pile foundation cantilever barrier wall structure of the present utility model include：Pile foundation 1 and cantilever
Barricade 2, pile foundation 1 are in a row disposed in firm ground through soft soil foundation A, cantilever barricade 2 be arranged on the top of pile foundation 1 and with
Be fixedly connected；Reinforcing pile 3 and cushion layer structure 4, reinforcing pile 3 are disposed in the soft soil foundation A of the inner side of cantilever barricade 2, pad
Rotating fields 4 are arranged on the composite foundation of the formation of reinforcing pile 3；Embedded bar 5, is arranged on the inner side of the bottom plate of cantilever barricade 2, and with
GSZ tenses connection in cushion layer structure 4；Roadbed filling body 6, placement in layers is in cushion layer structure 4 and the inner side of cantilever barricade 2.
Cantilever barricade 2 is undertaken as pile foundation 1, load caused by roadbed filling body 6 and superstructure, and solve soft soil foundation not
Uniform settlement, cantilever barricade 2 carry out closing slope and reinforcing to roadbed filling body 6, and reinforcing pile 3 solves the weak soil of the inner side of cantilever barricade 2
Ground A settlement issues and undertake upper load, the composite foundation and top roadbed filling that cushion layer structure 4 is formed as reinforcing pile 3
The buffer structure of body 6 so that be more uniformly stressed.GSZ in embedded bar 5 and cushion layer structure 4, which tenses, to be connected, can be with
Make soil want grid to produce an inside pulling force to cantilever barricade 2, solve the problems, such as that the horizontal distortion of cantilever barricade 2 is excessive.The knot
Structure solve thes problems, such as that pile foundation cantilever barricade horizontal distortion is larger on soft soil foundation, and has easy for construction, economy and ring
The features such as guarantor, there is popularizing application prospect.
The pile foundation 1 uses cast-in-situ bored pile, and stake is long and stake footpath meets sedimentation and stability requirement, the reinforcing pile (3)
Using cement mixing pile or rotary churning pile.
Reference picture 2, the cushion layer structure 4 by from bottom to top lay successively lower metalling 41, lower GSZ 44, in it is broken
43 compound composition of rock layers 42, upper GSZ 45 and upper metalling, embedded bar 5 and lower GSZ 44, upper GSZ 45
Tense connection.
Some of the utility model a kind of soft soil foundation pile foundation cantilever barrier wall structure described above that simply explains through diagrams are former
Reason, it is not intended to the utility model being confined in shown and described concrete structure and the construction method scope of application, thus it is every
Corresponding modification and the equivalent being utilized are possible to, belongs to the apllied the scope of the claims of the utility model.
