Description

A stone paving structure for anti-pan-alkali pool

technical field

The utility model relates to a stone paving structure for a water pool, in particular to a stone paving structure for an anti-pan-alkali water pool.

Background technique

The problem of efflorescence in waterscape is a common problem faced by domestic projects at present. The existing pool wall stone paving structure includes a concrete structure layer, a cement mortar leveling layer, a waterproof protection layer, and a finishing layer. If the existing paving process is adopted, it may be caused by factors such as stone paving is not full of slurry; caulking is not solid, and the caulking agent does not play its due role; the plastering mortar is not dried in the sun; the stone is not waterproof, etc. The resulting large-scale rework will not only seriously affect the landscape effect of the waterscape, but may also cause cost overruns and delay the construction period.

Utility model content

The purpose of the utility model is to provide an anti-efflorescence pool stone paving structure, which is stable in structure and low in cost, can effectively solve the problem of efflorescence of the surface layer of stone materials in the waterscape, and ensure the beautiful landscape effect of the waterscape.

In order to achieve the above purpose, the utility model provides an anti-pan-alkali pool stone paving structure, which includes a facing layer, a waterproof protection layer, a cement mortar leveling layer and a concrete structure layer arranged sequentially from top to bottom. A waterproof bonding layer and a low-alkali cement protective layer are sequentially arranged between the surface layer and the waterproof protective layer, and a stone powder cushion layer and a plain soil compaction layer are arranged sequentially below the concrete structure layer from top to bottom.

As a further improvement of the utility model, the waterproof adhesive layer adopts beneficial glue with a thickness of 30-40mm.

As a further improvement of the utility model, the concrete structure layer is made of impervious concrete with impermeability grade ≥ P6, C25.

As a further improvement of the utility model, the compaction coefficient of the plain soil compacted layer is 0.9.

As a further improvement of the utility model, the waterproof protective layer is made of K11 flexible waterproof slurry.

As a further improvement of the utility model, the facing layer adopts facing bricks spliced with close seams or facing bricks spliced with a gap of 5mm.

Compared with the prior art, the beneficial effects of the anti-pan-alkali pool stone paving structure of the present invention are as follows:

(1) A waterproof bonding layer and a low-alkali cement protective layer are provided between the finishing layer and the waterproof protective layer, and a stone powder cushion and a plain soil compacted layer are provided under the concrete structure layer. The plain soil compacted layer has little water seepage, The stone powder cushion can play the role of isolation, anti-pan-alkaline, and leveling, and the low-alkali cement protective layer and waterproof bonding layer have waterproof effect, so that it can effectively solve the problem of pan-alkali in the surface layer of the waterscape, and ensure that the landscape effect of the waterscape is beautiful, and the overall The structure is stable and the cost is low.

(2) Yijiao mud with a thickness of 30-40mm is used, so that the adhesion is good, the sealing is good, and it can block water, so as to effectively prevent efflorescence and facilitate construction.

(3) The compaction coefficient of the plain soil rammed layer is 0.9, so the water seepage is small, and the possibility of efflorescence is greatly reduced.

(4) The waterproof protective layer is made of K11 flexible waterproof slurry, so that the waterproof effect is good.

The utility model will become clearer through the following description in conjunction with the accompanying drawings, which are used to explain the embodiments of the utility model.

Description of drawings

Fig. 1 is a schematic diagram of the stone paving structure of the anti-pan-alkali water pool of the present invention.

Detailed ways

Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

Please refer to Figure 1, the anti-pan-alkali pool stone paving structure includes a facing layer 1, a waterproof adhesive layer 2, a low-alkali cement protective layer 3, a waterproof protective layer 4, and cement mortar arranged in sequence from top to bottom Leveling layer 5, concrete structure layer 6, stone powder cushion layer 7 and plain soil compaction layer 8. The facing layer 1 adopts facing bricks spliced closely or with a gap of 5 mm. When the facing bricks are spliced with a gap of 5 mm, after the surface of the facing brick is dry, clean the surface of the facing brick and use waterproof paint around the facing brick. Apply 1-2 layers to the crevices. The waterproof adhesive layer 2 adopts beneficial cement with a thickness of 30-40mm, and is bonded with the low-alkali cement protective layer 3. The beneficial cement with a thickness of 30-40mm has good adhesion, good sealing performance, and can block water, thereby effectively preventing Pan-alkaline, and easy to construct. The low-alkali cement protective layer 3 uses cement mortar of 1:2.5 (that is, the ratio of cement to mortar is 1:2.5), and the sand is fine sand so as to be combined with the waterproof adhesive layer 2 . The waterproof protective layer 4 is made of K11 flexible waterproof slurry, so the waterproof effect is good. K11 flexible waterproof slurry needs to be applied twice to form the waterproof protective layer 4, and the second application must be done after the first application is dry. The concrete structure layer 6 is made of impervious concrete with an impermeability grade ≥ P6, C25. The stone powder cushion layer 7 is mixed with 6% cement, so that the strength of the stone powder cushion layer can be improved, and the stone powder cushion layer can be hardened, so as to block water and further prevent efflorescence. The compaction coefficient of the plain soil tamping layer 8 is 0.9, so the water seepage is small, and the possibility of efflorescence is greatly reduced.

The utility model has been described above in conjunction with the best embodiments, but the utility model is not limited to the above-disclosed embodiments, but should cover various modifications and equivalent combinations based on the essence of the utility model.
