Description

A Simple Ground Moisture-proof Layer Applicable to Rural Residences in the South of the Yangtze River

technical field

The utility model relates to a simple ground moisture-proof layer suitable for rural residences in the south of the Yangtze River. The operation of the moisture-proof layer is simple and efficient.

Background technique

The first floor of residential buildings in the Jiangnan area is prone to moisture. There are three reasons: 1. Smooth and dense floor tiles have poor water absorption and cannot adjust the humidity of the air on the surface of the ground. 2. In spring and summer, the temperature rises, the relative humidity of the air is high, and the ground temperature is low. When the external hot and humid air enters the room and encounters the relatively low temperature ground, it is easy to condense and form small water droplets or condensed water, causing The return of moisture on the ground, this problem can be solved by improving the thermal insulation performance of the ground; 3. In coastal areas, due to the high groundwater level, when the pores of the floor material are very small, it is easy to cause the "capillarity" of groundwater vapor rising along the pores , "Capillary action" causes dampness on the ground at the corner of the wall and at the bottom of the column. This problem can be solved by using large-pore floor materials. However, in most residential buildings, due to the limitations of economic and technical conditions, basically no ground moisture-proof measures have been taken.

Contents of the invention

The purpose of this utility model is to provide a simple ground moisture-proof layer suitable for rural residences in the south of the Yangtze River for the deficiencies of the prior art.

The technical solution adopted by the utility model to solve its technical problems is as follows:

The utility model comprises plain soil tamping layers, large pebbles or block stone moisture-proof layers, cushion layers and surface layers arranged sequentially from bottom to top.

When the moisture-proof layer of large pebbles or blocks is arranged, the thickness of the moisture-proof layer of large pebbles or blocks is 150 mm to 200 mm;

The cushion layer is concrete, that is, soil material mixed and compacted with lime, clay and fine sand. In order to enhance the thermal insulation performance of the ground, inorganic thermal insulation materials such as boiler slag and fly ash are mixed in the concrete. The source of the material is wide and low price; the thickness of the cushion layer is 80mm-100mm; and a layer of non-woven geotextile is set between the cushion layer and the large pebbles or block stone moisture-proof layer, which is used to cut off and prevent the composite soil in the cushion layer from falling into large pebbles or block stone moisture barriers.

The surface layer is a clay brick, which has good air permeability and water permeability, and the thickness of the surface layer is 20mm;

The beneficial effects that the utility model can achieve:

The utility model adopts the nearby large pebbles or block stones in rural areas in the south of the Yangtze River as the moisture-proof layer, which not only makes full use of local resources, but also is simple and easy to operate. Prevent condensation and moisture on the ground.

Description of drawings

Fig. 1 is a structural representation of the utility model.

In the figure: plain soil compaction layer 1, large pebble or block stone moisture-proof layer 2, composite soil cushion layer 3, clay brick surface layer 4.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a simple ground moisture-proof layer suitable for rural residences in the south of the Yangtze River consists of a plain soil rammed layer 1, a large pebble or block stone moisture-proof layer 2, a composite soil cushion 3, and a clay brick surface arranged in sequence from bottom to top. Layer 4.

When the large pebble or block stone moisture-proof layer 2 is arranged, the thickness of the large pebble or block stone moisture-proof layer 2 is 150 mm to 200 mm;

The cushion layer is composite soil, and the thickness of the cushion layer is 80 mm to 100 mm; and a layer of non-woven geotextile is arranged between the cushion layer and the large pebble or block stone moisture-proof layer.

The surface layer is clay brick, and the thickness of the surface layer is 20mm.

Plain soil tamping layer 1 is combined with large pebbles or block stone moisture-proof layer 2 to make the subsurface structure more stable, and can also effectively prevent the rise of moisture; on the large pebbles or block stone moisture-proof layer 2, lay a composite soil cushion layer 3 , that is, the soil material made of lime, clay and fine sand mixed and compacted. In order to enhance the thermal insulation performance of the ground, inorganic thermal insulation materials such as boiler slag and fly ash are combined in the composite soil, which can effectively prevent the ground from being damp. The effect of long-term effective insulation of the ground. And a layer of non-woven geotextile is set at the large pebbles or the block stone moisture-proof layer 2 and the composite soil cushion layer 3, which is used to cut off and prevent the composite soil in the cushion layer 3 from falling into the large block pebbles or the block stone moisture-proof layer 2. Then lay the 20mm thick clay brick surface layer 4, which not only ensures the flatness and smoothness of the surface layer, but also realizes the hygroscopicity of the surface layer and effectively prevents moisture.
