UHPC fabricated soil nailing wall structure and construction method

Abstract

The invention relates to the technical field of geotechnical engineering supporting, in particular to a UHPC fabricated soil nailing wall structure and a construction method, and a UHPC fabricated soil nailing wall is formed by combining and assembling a plurality of soil nailing anchor rods and UHPC prefabricated panels; the soil nail anchor rod and the UHPC prefabricated panel are mutually fixed through the combination of a base plate and a fixing bolt; the UHPC prefabricated panels adjacent in the transverse direction and the longitudinal direction are sequentially connected in a sleeved mode through the horizontal metal connecting pieces and the vertical metal connecting pieces. The structure is simple and reasonable, the slope body can be reinforced in time, and deformation of the slope body can be effectively reduced. The UHPC prefabricated panel can be subjected to factory-like prefabricated maintenance, field installation and fixation according to design requirements, and then the soil nail anchor rod part is constructed, so that the construction cost can be reduced, the construction is more environment-friendly, the construction period is shortened, and the construction is more convenient.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering support, in particular to a UHPC assembled soil nail wall structure and a construction method. Background technique [0002] my country's topography and landforms are diverse, and the terrain is undulating. With the development of the economy and society, the infrastructure construction is also advancing rapidly. The construction of various engineering facilities in mountainous and hilly areas is gradually increasing, such as new roads and railways of various levels, large-scale reservoirs, and mining of mineral resources. Wait. With the increase of engineering construction and human activities, various types of slope disasters are also occurring, especially in mountainous areas with abundant rainfall, slope disasters are more frequent, and the property losses and casualties caused by slope accidents are also very serious. Landslides will also affect the operation of roads and rai...

AI Technical Summary

Problems solved by technology

When using dry spraying machines, the equipment used is relatively small, but the raw materials used are bulk cement, sand and stones, and the dust pollution on the construction site is relatively serious. When using more environmentally friendly wet spraying, the equipment and tools are relatively large, and the concrete used Concrete tank trucks need to be used for transportation, and its volume and weight are large. When the slope height is high and the site is small, or the transportation is inconvenient, the equipment is inconvenient to use, that is, it is difficult to apply to some support projects with complex site conditions.

Moreover, the on-site construction period is long, the on-site management is difficult, and the quality is difficult to guarantee
