Description
Technical Field
The invention belongs to the field of mountain road traffic facilities, and particularly relates to a mountain road buffer protection structure system.
Background
Slope engineering is of particular importance in the entire civil engineering, because of its high volume, technical difficulty and accident rate. The slope engineering object is a rock or soil body, the rock and soil body is naturally generated and can not be manufactured artificially, and the slope engineering object is characterized in that: the properties vary from place to place and from time to time; human understanding is not exhaustive; mechanical parameters cannot be accurately provided; the design level varies from person to person. These characteristics present great difficulties for the engineering construction, with the result that: the rock-soil body is not mastered properly, and the accident rate is high (the side slope accident rate in the building engineering is about 70% according to knowledge); the design schemes are different, and the cost difference is large; the geological conditions change greatly, and an economical and reasonable slope supporting method is lacked in many cases. At present, the main structural bodies adopted in the treatment of the high fill side slope are as follows: cantilever pile retaining wall, anchor pile retaining wall, gravity type retaining wall, reinforced earth retaining wall, batter pile self-balancing retaining wall and the like. Wherein: when the height of the gravity retaining wall is more than 8 meters, the engineering cost is increased quickly, and the economy is particularly poor for a high retaining wall; the bending moment of the cantilever pile retaining wall is the largest of all structural types, so the cost is very high; for tall retaining walls, anchor pile retaining walls have been used in recent years because anchor pile retaining walls have been used at a lower cost than the former two, while oblique piles have been used at the lowest cost from the balance retaining wall. The anchor pile retaining wall needs anchor pulling conditions, the inclined pile self-balancing retaining wall does not depend on the anchor pulling conditions, and the anchor pile self-balancing retaining wall has greater advantages in the aspects of economy and geological condition adaptation. The key of the batter pile self-balancing retaining wall technology lies in that: the slope thrust is reduced by adopting an inclined pile support; and the thrust bending moment of the side slope is balanced by adopting the reverse bending moment generated by the gravity of the upper retaining wall. The structure has the characteristic of reasonable stress, greatly reduces the construction cost of the side slope, has little dependence on geological conditions, and has strong applicability. Also due to this construction, a slope is required to have a certain inclination (typically 20 degrees from the vertical), which means that the slope stops take up some space. However, in some slope projects without a slope space, the application of the inclined pile self-balancing retaining wall is limited. The retaining wall is a structure for supporting roadbed filling or hillside soil and preventing the filling or soil from deforming and destabilizing. In the construction of the approach construction period of large and medium-sized urban road level bridges, the construction period of the road shoulder retaining wall is short. The limitations of surrounding buildings make it necessary to construct retaining walls of the prefabricated type. In addition, for those areas with poor foundation conditions and lack of stones, the use of fabricated retaining walls is the best choice because of the small weight of the wall, the small floor space and the low bearing capacity of the foundation. The fabricated retaining wall can shorten the construction period of a project, so that the construction has small negative influence on the surrounding social environment and ecological environment, the traffic pressure of urban road construction can be relieved, and the fabricated retaining wall plays an important role in promoting the construction of a low-carbon conservation-oriented society.
