Description
Technical Field
The utility model relates to a retaining wall technical field, concretely relates to check guest retaining wall.
Background
The Gabion retaining wall is also called a Gabion retaining wall, and is a flexible retaining wall formed by filling discrete materials such as soil or rock blocks in a net cage woven by a Gabion net. In China, the gabion structure is mainly applied to slope protection of riverways, but also shows excellent performance in highway application, and the novel structure shows better superiority than a rigid and semi-rigid structure in engineering application. The retaining walls with similar purposes are mainly classified into the following 5 types:
1. gravity type retaining wall
The gravity type retaining wall is generally made of rock blocks, bricks or plain concrete, is kept stable by the gravity of self-bearing, has high rigidity, is used in a good field of foundation soil, has the height of less than 5m, and has the characteristics of simple structure, easy material taking and convenient construction. However, in the environment of weak foundation soil and complex field, especially in the roadbed flushed by river water, the range is limited because the foundation soil is often subjected to uneven settlement or even collapse due to the fact that the foundation soil is emptied by flood.
2. Cantilever (wall) type retaining wall
The cantilever (wall) type retaining wall is made of reinforced concrete, its stability is mainly maintained by the gravity borne by the soil above the cantilever of the wall heel, the tension of the cantilever part is born by the steel bar, its advantage is that the wall body cross-section size is small, the requirement for bearing capacity of the foundation is not high, the construction is simple, the wall height can be greater than 5m, it belongs to the semi-flexible semi-rigid structure, when used in the ordinary working site, it has very good deformation resistance and non-uniform settlement resistance. However, when the water-saving anti-overturning water-saving device is used for water-saving water. In severe cases, the wall body can be greatly displaced, and collapse accidents are likely to happen when the wall body exceeds a certain height.
3. Buttress retaining wall
The counterfort retaining wall is made of reinforced concrete as the cantilever type retaining wall, the height of the wall is generally more than 10m, in order to increase the bending rigidity of the wall, one counterfort is arranged at intervals of 0.8-1 m in the longitudinal direction of the wall, the engineering quantity of the counterfort retaining wall is small, the requirement on the bearing capacity of a foundation is not high, but the construction process is complex, the construction cost is higher than that of other retaining walls, once the counterfort retaining wall is damaged, the counterfort retaining wall is difficult to repair, and the counterfort retaining wall is uneconomical when used for protecting a water-damaged roadbed.
4. Anchor rod and anchoring plate type retaining wall
The anchor plate retaining wall is composed of prefabricated reinforced concrete wall panels, upright posts, steel pull rods and anchor plates buried in the filled soil, and the anchor plate retaining wall is a light retaining structure generally composed of the upright posts, the wall panels and anchor rods. The retaining wall has the advantages of light structure, high flexibility, small engineering quantity, low counterfeiting and suitability for engineering with lower foundation bearing capacity. However, the construction process is complex, corresponding construction conditions are not provided in a plurality of water-damaged roadbed sections, the flexibility is large, the out-of-plane rigidity is low, large plastic deformation can be generated under the impact action of water flow and the action of uneven soil pressure, the repairing is difficult, the impact resistance is weak, the durability is poor, and the water-damaged roadbed is not suitable for working in the water-damaged roadbed fields.
5. Ordinary gabion retaining wall
The common gabion is also called a gabion retaining wall, and is a flexible retaining wall formed by filling discrete materials such as soil bodies or block stones in net cages woven by a gabion net. Ordinary gabion retaining wall cost is low, simple manufacture, and limited few, the practicality is strong. But its disadvantages are: the novel stone cage is formed by simply piling up a gabion net, is stable only by self gravity, is less in restraint, is easy to displace when impacted by water flow, and can be unevenly settled or collapsed due to the fact that a bottom soil layer is emptied by flood. In addition, fillers such as stones, filling soil and the like in the gabion mesh are easily taken out when flushed by flood to cause the inner part of the wall body to form a cavity, and the strength and stability of the wall body are affected.
In summary, five types of retaining walls commonly used at present have the following disadvantages when used in a water-damaged roadbed field: 1. the rigidity is high, and the method is not suitable for water-damaged roadbed and other soft soil layers; 2. the wall base is exposed under the washing of flood, so that the instability phenomenon is easily caused; 3. the drainage capacity of the wall body is poor, and rainwater is easily accumulated in the soil body behind the wall, so that the soil pressure on the wall body is increased and instability occurs. 4. The wall body is made of a material with low plane external rigidity and poor deformation resistance, and is easy to generate plastic deformation under the direct impact of water flow and difficult to repair. 5. The concrete retaining wall generally undergoes construction links such as reinforcing steel bar binding, formwork erecting and pouring, and the laying and ramming of roadbed seasonings behind the wall can be carried out only when the concrete reaches a certain strength, so that the construction period is long, and a certain technical threshold is provided, so that the concrete retaining wall cannot meet the requirements of quick, efficient and economic restoration of a water-damaged roadbed.
