Description
Technical Field
The invention belongs to the field of civil engineering, and particularly relates to a combined structure of a prefabricated alternate tooth whisker lattice and an anchor rod.
Background
The anchor rod lattice beam system is one new type of supporting and retaining structure, and is one comprehensive protecting measure utilizing grouted rubble, cast-in-place reinforced concrete or prestressed concrete to protect slope and anchor rod fixing. In recent years, the reinforcing technology of the anchor rod lattice beam system is greatly developed in slope reinforcement in China, particularly in reinforcement of weak slopes, so that the form of the supporting slope of the anchor rod lattice beam system is also developed and improved.
The anchor rod lattice beam system is a supporting system consisting of reinforced concrete lattices and soil layer anchor rods, and the supporting method is convenient to construct, economical and practical, and is widely applied to reinforcing treatment of cutting and embankment slope surfaces in line engineering such as highways and railways. In recent years, the lattice anchor rod combination reinforcement technology has the characteristics of strong practicability, small interference on the slope, good reinforcement, low cost and the like, can be widely applied to reinforcement and prevention of the high slope, can effectively enhance the self-stability capability of the high slope, and has important significance for reducing road diseases and protecting the relative stability of the ecological environment.
The anchor rod lattice beam system can be divided into a prestressed anchor rod lattice beam system and a non-prestressed anchor rod lattice beam system according to the type of an anchor rod; the cast-in-place anchor rod lattice beam system and the prefabricated anchor rod lattice beam system can be divided according to the type of the lattice beam.
Japan is the country which firstly applies the prestressed anchor rod lattice supporting method, and because of the special geomorphic geological conditions of Japan and the domestic demand conditions, a construction mode which adapts to the characteristics of Japan is gradually developed and formed, and is called as a Q & S (Quiek & Strong) frame construction method. The Q & S lattice beam construction method is that a rectangular reinforcement cage which is processed and assembled in a factory in advance is arranged on a side slope according to a rectangle or a rhombus, and then concrete is sprayed on the reinforcement cage. The Q & S construction method can be widely used in that the construction method is economical, rapid, and has significant advantages in reinforcing performance, construction and strength in the field.
China starts to invest in development and apply a cast-in-place anchor rod lattice beam structure from the last 90 th century, and is widely applied in China, and in the aspects of summarizing the experience of others and combining the conditions of China, the essence and the dregs of the people are taken out and absorbed and converted into an anchor rod lattice beam system in China. The system is widely popularized, not only because the system has good supporting effect, but also the arrangement is beautiful and flexible, is not limited by terrain conditions, and can be tightly attached to the slope surface. The common forms of the material are square, diamond, herringbone, arc and the like. However, the cast-in-place anchor rod lattice beam structure has poor performance and durability, the slope protection has low reliability, the most important construction is troublesome, the construction period can be seriously influenced, meanwhile, the cast-in-place anchor rod lattice beam structure is difficult to avoid different sizes, and certain influence is caused on use and attractiveness, and the prefabricated anchor rod lattice beam structure can exactly solve the series of problems.
In the 90 s of the last century in japan, a pc (prestressed concrete) lattice anchoring method was developed, which consisted of a precast prestressed concrete lattice beam and prestressed anchor cables. The construction method well combines the integral reinforcement of the side slope and the flexible support of the slope surface in the process of reinforcing the side slope. Is suitable for the side slope with poor integral stability and is also suitable for the side slope with a loose accumulation layer on the surface layer. The PC construction method has basically realized standardization and modernization, and the design specification is more perfect. In Japan, the PC lattice anchoring method has four types of structural forms, square, semi-square, cross and straight 25.
The combined structure of the prefabricated alternate tooth whisker lattice and the anchor rod is a better combined structure form. The prefabricated lattice and the anchor rod are welded to form a whole, and the problem that the integral transportation is difficult can be solved due to the fact that the volume of the lattice is large and the prefabricated alternate tooth whisker lattice; the most critical cast-in-place anchor rod lattice beam structure is extremely difficult to construct in the process of emergency repair of a side slope, and when the side slope is repaired by the aid of the combined structure of the prefabricated alternate tooth lattice and the anchor rod, the prefabricated lattice structure is only required to be lapped along the alternate teeth, a steel plate is covered, and a steel bar is inserted to complete installation, so that the emergency repair time can be greatly shortened, and the safety crisis and the economic loss are minimized.
As a new object, the combined structure of the prefabricated alternate tooth whisker lattice and the anchor rod is always in a specific environment, is suitable for various soil slopes and rock slopes, and has obvious effects on weak soil layers, rock stratums with severe shallow weathering and landslide bodies with large thickness of accumulated layers. The combined structure of the prefabricated alternate tooth whisker lattice and the anchor rod can be widely applied to various slope reinforcements, such as high slope stability and skid resistance, retaining wall and cavern reinforcement, dam foundation and dam body stability reinforcement and earthquake resistance, and has obvious technical and economic superiority in engineering practice. Along with the development of the traffic, water conservancy, mining and energy cause of China, a great amount of artificial slopes appear, so that the landslide disaster problem is gradually highlighted, and therefore, the combined structure of the prefabricated alternate tooth whisker lattice and the anchor rod plays an increasingly important role in the management of the slopes.
