Description
Technical field
The utility model relates to building, field of civil engineering, particularly relates to a kind of retaining wall.
Background technology
The earthquake calamity data such as Tai Wanji-collection earthquake, China's Wenchuan earthquake, Japanese Osaka-Kobe earthquake and U.S.'s Northridge earthquake show, geosynthetics has certain anti-seismic performance.Along with the development of Geosynthetics Technology, the continuous maturation of reinforced earth technology, the synthetic materials such as geotextiles, geo-grid has been widely used in the earth structure of the geotechnical engineerings such as highway, railway, ground, side slope and embankment.But geotextiles or geo-grid are two-dimension plane structure, limit by material structure, every layer of effective control area of reinforcement material is limited, for guaranteeing that native barricade is stablized, need to arrange multilayer reinforcement material and longer reinforced length, improve construction cost, waste a large amount of manpower and materials.The performance test of domestic and international system and model testing, result shows, novel three-dimensional geogrid is more stable than the performance of conventional grates, and in the plane, its multidirectional stressed superior performance, is particularly useful for moving loads, point load and local load situation.
Utility model content
For Problems existing in background technology, the utility model provides a kind of retaining wall structure based on rubbery chip and three-dimensional grill reinforce flexibility, and concrete technical scheme is as follows:
A kind of retaining wall, it is characterized in that: comprise metope layer (1), wall backing layer (3), mixed layer (2) between metope layer and wall backing layer, the top of described mixed layer (2) and wall backing layer (3) is provided with wall top (5), lacing wire structure (4) is embedded with in described mixed layer (2) and wall backing layer, lacing wire structure (4) is positioned at the top of mixed layer (2) and wall backing layer (3), and parallel with the substrate of retaining wall, lacing wire structure (4) is three-dimensional geogrid shape; Described mixed layer (2) described mixed layer (2) is rubbery chip-sand composite soil, includes elastic caoutchouc (20) fragment and sand.
The volume content of described elastic caoutchouc (20) fragment in mixed layer (2) is 50% or 75%.
Described metope layer (1) is cantilevered or modular retaining wall panel.
Described elastic caoutchouc (20) is damaged tire.
The material of described wall backing layer is building filler,
building filler is existing, is earth material and/or building stones.
In preference: three-dimensional geogrid is developed on the basis of traditional geo-grid, has high-strength pulling-resisting modulus of elasticity.It has employed triangular structure more stable on geometry and mechanics, and is tension type macromolecular material grid, each node has six roots of sensation rib, stressedly be similar to circle, there is good plane torsional rigidity, effectively can form interlocking with grogs, thus suppress the lateral displacement of grogs.Three-dimensional grid and grogs acting in conjunction, form mechanics stabilized zone, when being subject to geological process, by the vertical deformation of the soil body equably to horizontal direction diffusion, the shearing resistance deformability of the soil body can be given full play to, thus reduce the disturbance to the soil body.In addition, three-dimensional grid is connected in length and breadth, improves globality and the stability of reinforced structure, effectively can limit the distortion of the soil body.
Junked tire tensile strength is high, good toughness, durability, resistance to wear, anti-aging, antidetonation crashworthiness is excellent, the construction of tire reinforcement is fast simple, with low cost, there are good distortion conformability and long-time stability, environmental protection (to environment and underground water without negative effect), not perishable (usual underground water acid condition pH value is 4-5, and generally, tire is in this pH value environment, and it is aging, loss is negligible).Cut into pieces by junked tire, tire debris and sand are mixed into rubbery chip-sand composite soil by proper proportion and use as soil-baffling structure behind bed course, can play reinforcement, antidetonation, prevent the multiple compound actions such as liquefaction, draining.Conventional reinforced earth barricade does not generally arrange bed course behind, and should changing of adopting flexible tire debris earth structure preferably to bear is large, modulus of deformation is lower, the secondary stress produced when large sstrain is lower, there is higher damping, geological process more effectively can absorb energy, the lateral deformation that retaining wall structure causes due to earthquake can be effectively reduced, so more can be adapted to and not be destroyed, comply with the nature, at utmost reduce loss.
Under horizontal vibration, the horizontal movement top of soil barricade is large, bottom is little, be similar to the horizontal jitter of semi girder, for improving the resistance to overturning of retaining wall, consider to carry out reinforcement process to barricade top, use novel three-dimensional geogrid to carry on the back lacing wire at wall, make itself and rolling earth behind retaining wall acting in conjunction, greatly improve barricade resistance to capsizing, thus meet shockproof requirements.External correlation test result also shows, the part of retaining wall top reinforcement material extends can significantly improve its seismic stability.
This composite reinforced retaining wall structure tire debris and the acting in conjunction of three-dimensional grid, have mitigation pressure-bearing concurrently, reinforcement antidetonation, effective draining, prevent liquefaction function, and the reduction of erection time, cost-saving simultaneously, environmental protection.
When metope layer is cantilever structure, the novel three-dimensional grid of U-shaped bar connecting and metope layer can be used, when metope layer is precast module type panel, such module can be connected by the reserved steel bar of pin, backboard with muscle material, also can be directly fixed on by muscle material in the tenon mouth of building by laying bricks or stones.
The utility model only suitably arranges lacing wire at the top that retaining wall structure easily destroys, and non-full paving, and the permanent position of every layer of novel three-dimensional geogrid is parallel with substrate.Described wall facing inner wall is provided with U-shaped reinforcing bar, and the syndeton of novel three-dimensional geogrid to be fixed on reinforcing bar thus to be connected with metope layer.
Compared with conventional Geotextile Reinforced Earth Retaining Wall, the present invention has following advantages and good effect:
1. novel three-dimensional geogrid in three directions solids and grogs acting in conjunction, can be formed stable interlocking structure, greatly increases the effective range to the soil body, thus reduce the number of plies of reinforcement material setting;
2. barricade behind tire debris and sand mixing and rubbery chip-sand composite soil do bed course, can play reinforcement, antidetonation, prevent the multiple compound actions such as liquefaction, draining;
3. tire debris and sand mixing and rubbery chip-sand composite soil reinforcement cushion are without the need to compacting, the reduction of erection time, construct simple, with low cost;
4. novel three-dimensional grid retaining walls carry on the back lacing wire, junked tire fragment to mix with sand i.e. rubbery chip-sand composite soil be used as wall back pad layer make earth structure globality and stability better, improve soil-baffling structure anti-seismic performance more significantly;
Make full use of discarded object and on-the-spot filler, economic environmental protection.
