Anti-toppling retaining wall building block

Abstract

The invention discloses an anti-toppling retaining wall building block, which comprises a straddle solid building block. The anti-toppling retaining wall building block is characterized in that: the straddle solid building block (1) is at least provided with a horizontal clamping tenon (2) and a horizontal clamping groove (3); and after being built in place, the horizontal clamping tenons (2) andthe horizontal clamping grooves (3) of the straddle solid building blocks of the upper and lower layers form a horizontal nested structure. The built wall has the characteristics of strong integrity,good anti-toppling capability, firm clamping and anchorage for bars, high flatness and the like, is convenient and quick for construction, is suitable for various retaining structures in the fields of traffic, water conservancy, municipal administration and buildings, and is particularly suitable to be used as a retaining wall.

Description

technical field [0001] The invention relates to an anti-tilt retaining wall block, in particular to a dry-built concrete block for a reinforced retaining wall. Background technique [0002] At present, the shapes of blocks used in reinforced retaining walls are various. Among them, self-embedded concrete blocks are a rising star. Because of their simple structure, convenient and fast construction, and low cost, they are more and more widely used. These self-embedded concrete blocks are staggered layer by layer through a single row of blocks. The upper block and the lower block are nested in the vertical direction to limit the horizontal displacement of the block, so there is no need for slurry and anchor bolts. , can be dry-built to form a retaining wall. However, since they are only nested in the vertical direction and there is no horizontal nesting structure, the relative vertical displacement between the upper and lower blocks cannot be limited. Turning, the upper and l...

Problems solved by technology

However, because the reinforcement is bent many times inside the wall, it is not in a flat state. After bearing the tension and tightening, the bending place will generate upward or downward force on the upper and lower blocks. The upward additional lifting force has an adverse effect on the stability of the retaining wall, and because there is no horizontal nesting structure between the upper and lower blocks, the blocks only rely on the self-weight pressure of the upper masonry and the friction with the soil to maintain balance, so it is easy to At the same time, the clamping force on the reinforcement is weakened, the anchor structure of the reinforcement is damaged, and the reinforcement is loosened, so the retaining wall loses effective traction, and the overall instability is destroyed

[0004] The dry-built reinforced retaining wall does not need to use slurry, and the blocks are directly built up layer by layer. Therefore, any deviation in the size of the blocks or uneven placement will affect the quality of the blocks in this layer and the layers above. Flatness, which not only affects the quality of the masonry, but also affects the anchoring quality of the reinforcement. If it is not discovered and adjusted in time, it will be adjusted when the accumulated deviation of the multi-layered layers is relatively large, which will lead to rework, resulting in a huge waste of manpower and material strength. , wasting time

However, problems such as the deviation of the size of a single block or uneven placement are not easy to find with the naked eye. Each block is controlled by instruments and equipment to adjust the flatness, which is time-consuming and laborious, and it is not easy to implement. Therefore, dry block There have always been problems in the control and adjustment of the flatness of earth wall blocks
