Description

Concrete wall for retaining grains in wine lees storage yard Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a lees retaining concrete wall of a lees storage yard structure. Background Art

[0002] A lees yard is essential for distiller's grains resource utilization projects. To effectively utilize the yard's space and increase storage capacity, the yard structure requires numerous concrete walls to retain the grains. Furthermore, to meet the requirements for impermeability of the lees liquid, the lees yard structure typically incorporates a structural, impermeable reinforced concrete floor. Current design methods for retaining walls generally draw on those used for earth retaining walls.

[0003] The load diagram for calculating the anti-slip performance of retaining walls in conventional design methods is shown in Figure 1. The load that generates the horizontal sliding force of the retaining wall is the horizontal force F generated by the lees and the underlying soil layer. j , resisting horizontal force F j Passive earth pressure F of fill behind the wall s1 The friction force F generated by the foundation s2 , satisfying F s1 +F s2 =kF j , where k is the structural design safety factor. s2 It is mainly caused by the deadweight of the foundation slab and the fill and lees above it. The higher the retaining wall is, the greater the horizontal force is. In order to resist the horizontal force, the width of the foundation wall heel needs to be increased proportionally.

[0004] The load diagram of the retaining wall anti-overturning calculation in the conventional design method is shown in Figure 2. The load that produces the horizontal force of the retaining wall overturning is the horizontal force F generated by the lees and the underlying soil layer. j , resisting the horizontal overturning force F j Passive earth pressure F of fill behind the wall s1 and the weight of the foundation and its overlying fill and lees G s1 , satisfying F s1 K1+G s1 K2=mF j H1, where m is the structural design safety factor. s1 It is mainly caused by the deadweight of the foundation slab and the fill and lees above it. The higher the retaining wall is, the greater the horizontal force is. In order to resist the horizontal force, the width of the foundation wall heel needs to be increased proportionally.

[0005] It can be seen that the existing retaining wall design method fails to combine the retaining wall design with the anti-seepage concrete base plate design, which leads to the retaining wall foundation size being designed to be larger in order to meet the requirements of anti-slip stability and anti-overturning stability; at the same time, in order to resist horizontal loads, the retaining wall is equipped with more steel bars.
