Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

Fig. 1 is a structural schematic diagram of a moisture-proof and heat-insulating ground system provided by an embodiment of the present invention. As shown in Figure 1, a moisture-proof and heat-insulating ground system, the system includes:

base layer 1;

The moisture-proof layer 2 is laid on the base layer 1;

The insulation layer 3 is laid on the moisture-proof layer 2;

The inorganic thermal insulation mortar layer 4 is laid on the thermal insulation layer 3 .

In the embodiment of the utility model, the base layer 1 provides a supporting foundation for the ground system, preventing local collapse, deformation and damage of the ground system. In this embodiment, the base layer may be formed by pouring concrete, or laid with bricks or rubble, or rammed lime soil, composite soil or plain soil to form the base layer. The materials used for the base layer in the above embodiments are all economical and readily available materials, which can be reasonably selected according to local conditions, and the construction method is simple and easy. The main function of the moisture-proof layer 2 is to isolate the moisture of the earth and prevent the moisture from affecting the ground system and the space above the ground system. In this embodiment, waterproof roll material or PVC plastic film is used as the moisture-proof isolation layer. On the one hand, the materials are cheap and easy to obtain, and on the other hand, these materials have relevant national standards, so the quality is easy to guarantee. The joints of the waterproof membrane or PVC plastic film are fixed by bonding or welding to ensure the integrity of the moisture-proof layer. During construction, the empty laying process is adopted to not bond with the base layer as a whole, so as to avoid stress and strain on the moisture-proof layer during uneven settlement of the base layer, which will cause the moisture-proof layer to be torn. On the one hand, the thermal insulation layer 3 plays the main role of thermal insulation of the ground system, effectively preventing the heat in the space above the ground system from exchanging heat with the earth, and on the other hand, plays a role of protection for the moisture-proof layer. In this embodiment, prefabricated insulation boards are used to lay the insulation layer 3 . Insulation layer 3 is dry-laid and flat without adhesive materials. On the one hand, it does not interfere with the moisture-proof layer below. On the other hand, no adhesive materials are used between the insulation panels to avoid the phenomenon of cold and heat bridges affecting the overall thermal insulation effect of the insulation layer. . The prefabricated insulation board in this embodiment can be molded polystyrene board, extruded polystyrene board, rigid polyurethane foam board, foam glass board, aerated concrete board or foam concrete board. The prefabricated thermal insulation board material selected in this embodiment has a low thermal conductivity and good thermal insulation effect, and at the same time, the supply is sufficient in the market and is easy to purchase. On the one hand, the inorganic thermal insulation mortar layer 4 has a good thermal insulation effect, and together with the thermal insulation layer 3, it can effectively prevent the heat in the space above the ground system from exchanging heat with the earth, thus reducing the maintenance of the ground system. The temperature of the space needs to consume energy. On the other hand, the inorganic thermal insulation mortar layer in this embodiment is a non-combustible material, which is laid on the thermal insulation layer to protect the thermal insulation layer from being ignited by the fire source that may come from the room. The ground system of the utility model integrates moisture-proof, heat-insulating and fire-proof, and conforms to the development direction of ground engineering of multi-storey or low-rise industrial and civil buildings in the future. On the premise of ensuring safety, the energy consumption is greatly reduced, and it has remarkable economic and social benefits.

When surface decoration is required for other requirements such as comfort in use, the ground system also includes a leveling layer 5 and a ground decoration layer 6. The foundation maintains the stability of the ground decoration layer 6 and prevents its deformation; the ground decoration layer 6 is laid on the leveling layer 5 .

Splicing is often required when laying the moisture-proof layer. When splicing waterproof coiled materials or PVC plastic films, the width of the lap joints should not be less than 10cm, and the lap joints should be fixed by bonding or ultrasonic welding. Make the moisture-proof layer form a solid structure, improve the moisture-proof effect and service life. Generally speaking, the thickness of the waterproof membrane is not less than 2mm, and the thickness of the PVC plastic film is not less than 0.1mm. This thickness provides sufficient strength and moisture resistance.

The insulation layer is laid with prefabricated insulation boards, no bonding materials are required during construction, and the dry laying is smooth. The thickness of the insulation board is not less than 5cm, which ensures the insulation effect. The selected insulation board can be divided into organic insulation board and inorganic insulation board according to the material. The compressive strength of the organic insulation board is not less than 0.15MPa, and the compressive strength of the inorganic insulation board is not less than 0.3MPa, which ensures the strength of the insulation board. The insulation board is mainly selected from: molded polystyrene board, extruded polystyrene board, rigid polyurethane foam board, foam glass board, aerated concrete board or foam concrete board, etc.

The inorganic thermal insulation mortar layer adopts vitrified microbead thermal insulation mortar or expanded perlite thermal insulation mortar, which is applied on-site by plastering and pressing, and the thickness is not less than 5cm. After hardening, the compressive strength of the thermal insulation mortar shall not be less than 0.2MPa.

The leveling layer is leveled with cement mortar on site, and the anti-cracking reinforced steel mesh is built in during construction to ensure the strength of the leveling layer and avoid cracking. The thickness of the leveling layer is preferably 1-2cm, and the compressive strength after hardening is not less than 20MPa.
