Background
Retaining walls are structures that prevent the collapse of the earth mass. Currently, common retaining walls include gravity type, weight balance type, reinforced concrete cantilever type, counterfort type, and the like.
The gravity type retaining wall and the balance weight type retaining wall prevent the soil body behind the wall from slipping and overturning and keep stable by means of the weight of materials. The closer the center of gravity is to the soil body, the higher the efficiency of the retaining wall is, therefore, most of the retaining walls are of lying inclined structures with the bottom expanded outwards and the top contracted inwards, and the defects are that the top recovery loses the use area when the bottom presses the planned red line.
The reinforced concrete cantilever type and counterfort type retaining wall is integrally cast by an upper wall plate and a lower bottom plate into a whole, wherein the upper wall plate mainly has the functions of preventing the soil body behind the wall from sliding and transmitting the pressure of the soil body to the bottom plate, the lower bottom plate transmits the force of the upper wall plate to a foundation, and the soil on the wall plate, the bottom plate and the bottom plate jointly act to prevent the soil body behind the wall from sliding, overturning and keeping stable. The upper wall plate of the retaining wall can be vertically manufactured, and the lower bottom plate needs to be provided with large feet extending out of the wall in order to balance the bending moment caused by the soil pressure. The disadvantage is that if the planning red line is pressed, the large foot of the lower bottom plate of the upper wallboard must extend out of the planning red line, otherwise, the planning red line is pressed by the large foot, the upper wallboard must retreat into the red line for a certain distance, and the upper use area is also lost.
