Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, concretely is a floor optimization drainage bearing structure based on fine reinforcement and geotextile combination. BACKGROUND

[0002] In the field of building engineering, as the key part of the building and ground contact, the performance of the floor is directly related to the use function, safety and durability of the building. The traditional floor drainage structure, especially the widely used drainage plate structure, has many problems that cannot be ignored.

[0003] The drainage plate usually has a large void ratio, which provides a channel for the discharge of water to a certain extent, but also causes the existence of "weak layer" below the floor, which makes the force transmission poor, so that the floor is difficult to withstand bending and tension. At the same time, the thickness of the drainage plate is thick, which is easy to form a weak layer under the floor layer. Under the action of dynamic load generated by frequent driving of vehicles and long-term static load in the area bearing heavy load, such as industrial plant, large parking lot, etc., the weak layer cannot effectively disperse and transfer pressure. This makes the connection between the floor layer and the structure layer gradually damaged, resulting in cracking, settlement and separation of the floor and the structure layer. Not only affects the normal production and business activities, but also greatly increases the maintenance cost and downtime.

[0004] The drainage efficiency of the traditional drainage plate is limited by its structure and material properties. In the face of heavy rainfall, large amount of ground water or high humidity environment, the drainage speed of the drainage plate is difficult to meet the actual demand, resulting in serious water accumulation on the floor surface. The water accumulation soaks the floor for a long time, not only accelerates the damage of the floor structure, but also may penetrate to the structure layer, causing damage to the foundation of the building. Moreover, the durability of the drainage plate is poor, and its performance will gradually decrease under the long-term water erosion and environmental action, further weakening the drainage and bearing capacity.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a floor optimization drainage bearing structure based on fine reinforcement and geotextile combination. CONTENT OF UTILITY MODEL

[0006] The utility model aims at providing a floor optimization drainage bearing structure based on fine reinforcement and geotextile combination.

[0007] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0009] Preferably, a waterproof layer is arranged between the reinforcing mesh and the structural layer.

[0010] Preferably, the reinforcing mesh is subjected to sand blasting treatment to Sa2.5 level and then subjected to corrosion protection treatment using a polyurea coating.

[0011] Preferably, the reinforcing mesh is fixed by binding a plurality of fine steel bars with fine iron wires to form a stable grid structure, wherein the fine steel bars are selected from hot-rolled smooth round steel bars with a diameter of 4-6 mm HPB300.

[0012] Preferably, after the geotextile is laid, fine gaps formed on both sides of the fine steel bars constitute a mesh fine water channel, and the mesh fine water channel is communicated with a surrounding drainage ditch and a water collecting well.

[0013] Preferably, the geotextile is selected from polypropylene staple needle-punched geotextile with a unit area mass in a range of 200-300 g / m².

The bending and pulling effects on the floor are significantly reduced, and the risks of floor cracking and settlement are reduced. The geotextile forms fine water channels on the side surfaces of the steel bars together with the steel bars, and also serves as an upper and lower isolation layer, thereby reducing the reflection cracks when the upper and lower layers are inconsistent in deformation, further enhancing the overall stability of the structure, and improving the anti-deformation ability of the floor.

[0023] 3. Improve durability: fast drainage effectively avoids the floor to be in the water environment for a long time, reduces the erosion and freeze-thaw damage of water to the floor material, thereby prolongs the service life of the floor.
