Cutting supporting and retaining device with dual balance weight plates

Abstract

The invention discloses a cutting supporting and retaining device with dual balance weight plates. The device comprises a retaining wall panel, an upper balance weight plate and a lower balance weight plate, wherein the upper balance weight plate and the lower balance weight plate are arranged on the outer side of the retaining wall panel and are perpendicular to the retaining wall panel, the lower balance weight plate is arranged at the bottom of the retaining wall panel, and the upper balance weight plate is located above the lower balance weight plate. With the cutting supporting and retaining device with dual balance weight plates, the manual labor intensity on site can be reduced, the operating conditions are improved, the environmental protection effect is improved, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of road cutting engineering, in particular to a double balance weight plate type road cutting support device. Background technique [0002] At present, the existing road and railway slope retaining structures often adopt a gravity-type inclined structure. The breast slope in this structure is generally 1:0.1 to 1:0.2, and the construction conditions for it are manual excavation. However, with the popularization of large-scale machinery, all slopes have now been excavated by large-scale machinery, and the slope of the temporary construction slope is much slower than 1:0.2. The rock-soil boundary conditions behind it changed from original surrounding rock to backfill soil, and the earth pressure increased significantly. Because the gravity retaining wall needs to rely on its own gravity to resist the earth pressure, it needs a lot of concrete and stone, and it occupies a large area, requires more excavation o...

Problems solved by technology

However, with the popularization of large-scale machinery, all slopes have now been excavated by large-scale machinery, and the slope of the temporary construction slope is much slower than 1:0.2. The rock-soil boundary condition behind has changed from the original surrounding rock to the backfill soil, and the earth pressure has increased significantly

Because the gravity retaining wall needs to rely on its own gravity to resist the earth pressure, it needs a lot of concrete and stone, and it occupies a large area, requires more excavation operations, and has poor environmental protection; in addition, the plain concrete gravity retaining wall has poor seismic performance. It relies on concrete to resist tension, so the material performance cannot be fully utilized, and the economy is poor; while the mortar-built stone retaining wall has even poorer earthquake resistance, and the labor intensity of workers during construction is extremely high, so it is difficult to effectively guarantee the construction quality

The above problems all indicate that the traditional plain concrete or grouted gravel gravity structure has lagged far behind the actual material, design and construction technical conditions, so it is necessary to update the technology
