Embodiment
[0051] A block stone retaining wall structure such as figure 1 As shown, the gravel filter layer 5, the retaining wall body 1, the cement mortar layer 3 and the stone material 2 are arranged in sequence, and the gravel filter layer 5 is located between the retaining wall body 1 and the slope.
[0052] Such as figure 1 As shown, a plurality of drain pipes 14 of PVC material are pre-embedded in the retaining wall body 1 to form drain holes with a diameter of 100mm. The drain pipes 14 are arranged along the length direction of the retaining wall body 1 at an interval of 2-3 m, and are arranged staggered up and down. The distance between the lower drain pipes 14 and the ground is 50 cm.
[0053] Such as figure 2 As shown, the thickness of the gravel filter layer 5 is 0.3m, and it is arranged along the length direction of the retaining wall body 1 . One end of the drain pipe 14 towards the gravel filter layer 5 is provided with a sandless concrete slab 17 , which is embedded in...

The invention belongs to the technical field of support protection structures and discloses a block stone retaining wall structure. According to the main points of the technical scheme, the block stone retaining wall structure comprises a retaining wall main body, a stone material and a cement mortar layer, wherein a plurality of flanges are arranged at the side, facing the cement mortar layer, ofthe retaining wall main body; a plurality of fixing steel bars are pre-buried in the retaining wall main body, and the fixing steel bars penetrate out from the side facing the cement mortar layer ofthe retaining wall main body; grooves are formed in the corners, corresponding to the fixing steel bars, of the stone material; and metal wires are glued in the grooves, and the ends, far from the stone material, of the metal wires are wound on the fixing steel bars. The invention discloses a construction technology used for building the block stone retaining wall structure. According to the mainpoints of the technical scheme, the technology comprises: carrying out measurement and setting-out, excavating a foundation pit, casting the retaining wall main body, paving a gravel reverse filteringlayer, and paving a decorative stone material. The stone material paved on the outer wall of the retaining wall main body can be stably connected with the retaining wall main body, and the stone cannot fall for years.
Description
technical field [0001] The invention relates to the technical field of retaining and protecting structures, in particular to a construction technique for building block stone retaining wall structures. Background technique [0002] For steep slopes, embankment sections or steep cutting slope sections, etc., because the slope is too large, the shallow soil is difficult to fix on the slope surface, and it is often necessary to set up a retaining structure to prevent the slope soil or fill from slumping. Retaining wall is the most commonly used support and protection structure in engineering construction. It is mainly used to bear the lateral earth pressure of the soil, support the embankment fill or slope soil, and prevent the fill or soil from deformation and instability. [0003] The Chinese patent with the publication number CN104929150A discloses a construction method of rigid-flexible composite pre-displacement retaining wall, which includes the following steps: a, measur...
