Description

Inclined type gabion retaining wall

Technical Field

The utility model belongs to the hydraulic engineering field, concretely relates to face upward inclined retaining wall.

Background

The gabion net cage 1 (figure 1) is a core material of the gabion retaining wall, and takes a Golgin plated low-carbon steel wire mesh as a raw material, and the material has the characteristics of corrosion resistance, wear resistance and high strength. And hard stones are filled into the gabion net box 1, and the gabion net boxes with a plurality of sizes are wound and fixed through steel wires to form a whole, namely the gabion retaining wall. As shown in fig. 2, the gabion retaining wall 2 is generally designed in a manner that a breast wall is a step shape and a back wall is a vertical type, the staggered position can serve as a working platform for workers, and the workers can work by carrying hardware tools such as wire clippers, hammers, crowbars, no. 14 iron wires and the like.

The existing gabion retaining wall 2 adopts a construction mode of 'firstly building a wall and then backfilling', and when large-scale rolling equipment is used for backfilling and rolling back soil of the wall, the situation that the constructed gabion retaining wall on the same floor near a rolling part is squeezed and displaced can be caused, so that only small-scale rolling equipment can be used for completing backfilling and rolling the back soil of the wall. Because the construction height of the retaining wall is continuously increased, the visual field of an operator of the stone filling machine is blocked, and according to construction experience, when the stone filling machine performs filling operation on a fifth-order gabion net cage and an upper gabion net cage of the retaining wall, the stone filling machine can only ensure the effective operation time of the operator by taking a wall back backfill layer top as an operation platform, so when a small machine tool is adopted for construction, the wall back soil backfilling and rolling working period is long, the efficiency is low, the height of a wall back backfill layer cannot follow the construction height of the retaining wall, the stone filling machine cannot effectively enter the fifth-order retaining wall for construction in a forward-following manner when the fourth-order retaining wall is completed, even if the fifth-order retaining wall and the upper gabion net cage are subjected to filling operation, the stone filling machine can also perform cross construction due to low-efficiency operation of the small rolling machine tool, the efficiency between working procedures is reduced in double, vicious circle is caused, and the idle time exists in an operation team group, and the linear engineering with tight technological connection and high technological repeatability of the gabion retaining wall cannot be met.

If the existing vertical gravity type gabion retaining wall adopts a construction mode of 'backfilling first and then building the wall', each layer of backfilled soil needs to be made into a vertical step with the height of 0.7 m, and the backfilling material has higher quality requirements. Only the compact type gravels soil with the grain content of more than 38mm and 30 to 50 percent can be selected for backfill rolling operation. The backfill material has small selectable range and strict standard, and is not beneficial to construction.
