Description
Technical field
The utility model relates to slope retaining technical field, specifically a kind of cast-in-situ steel reinforced concrete gravity retaining wall knot
Structure.
Background technique
Gravity retaining wall refers to the retaining wall that soil body lateral pressure is resisted by wall self weight.Gravity retaining wall can
It uses block stone, slabstone, concrete precast block as masonry, or one-piece casting is carried out using piece stone concrete, concrete.Half gravity type
Concrete can be used in retaining wall or rare-reinforcement concrete pours.Gravity retaining wall can be built up with barnacle or concrete, generally all be done
At simple trapezoidal.Its advantages are to gather materials on the spot, easy for construction, good economical benefit.So gravity retaining wall is in China's iron
It is widely used in the engineerings such as road, highway, water conservancy, bay, mine.
During slope project supporting and retaining system, most commonly seen retaining structure is gravity retaining wall, traditional gravity type retaining wall
Mostly use block stone, slabstone, the concrete precast block as masonry, gravity retaining wall is to maintain earth-retaining with retaining wall self gravity
Wall soil pressure effect under stabilization, it is necessary to have enough overall stability and structural strength, be just able to satisfy antiskid, shearing resistance,
The requirement such as antidumping, therefore the masonry volume of gravity retaining wall is often larger, the construction period is longer, higher cost, while base
Plinth excavated volume is larger, often needs to handle more spoir, and masonry metope is high steep, it is difficult to which multiple green, visual Landscape is often bad.
Therefore, traditional gravity type retaining wall disadvantage is obvious.
