Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building waterproofing, in particular to a concealed concrete water dispersion structure. Background Art
[0002] Drainage is a protective layer laid around a building to prevent the infiltration of rainwater and water used for production and daily life. The purpose of installing a drain is to quickly drain away water accumulated near the base of the building's exterior walls and prevent dripping water from the eaves from eroding the soil around the exterior walls. This reduces the risk of water soaking the walls and foundations, protects them, and extends the life of the building.
[0003] Currently, scattered water is poured with cement mortar or concrete to form a sloped surface. The single color of the exposed surface and the unique function of the surface cannot meet the needs of development. Adding green plants or landscapes around buildings where people live or move around can not only enhance the visual effect, but also absorb harmful gases and dust, purify the air, and reduce noise to a certain extent.
[0004] Therefore, it is necessary to design a dispersion structure that can not only protect the foundation of the building, but also plant green plants and beautify the environment. Summary of the Invention
[0005] The utility model provides a concealed concrete water dispersion structure, in which the concealed water dispersion layer can effectively drain the ground water near the external wall foundation, and a planting soil layer can be laid above the concealed water dispersion layer for planting green plants.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A concealed concrete dispersion structure, which is arranged around the foundation of the building's outer wall; the dispersion structure includes, from bottom to top, a rammed earth layer, a concealed dispersion layer and a planting soil layer; the concealed dispersion layer includes, from bottom to top, a pebble grouting mortar layer, a C20 fine stone concrete layer and a waterproof geotextile layer; the pebble grouting mortar layer is arranged on the surface of the rammed earth layer, and the planting soil layer is arranged on the surface of the waterproof geotextile layer; an insulation layer is provided on the outer side of the building's outer wall, and a waterproof coating is provided on the outer side of the insulation layer; a caulking paste is provided between the waterproof coating and the waterproof geotextile layer.
[0008] The exterior wall of the building includes a foundation beam and a brick wall; the foundation beam is an "L"-shaped structure, and the "L"-shaped structure includes a horizontal part and a vertical part; the ends of the pebble pouring mortar layer and the C20 fine stone concrete layer are arranged in sequence on the horizontal part, the brick wall is close to the vertical part, and the bottom end of the brick wall is in contact with the C20 fine stone concrete layer.
[0009] The outer end of the C20 fine stone concrete layer is retracted inward by 100 to 150 mm to form a step structure with the pebble grouting mortar layer; the waterproof geotextile layer covers the outer ends of the C20 fine stone concrete layer and the pebble grouting mortar layer.
[0010] The surface of the buried water dispersion layer and the surface of the rammed earth layer below the buried water dispersion layer are both inclined downward to form a slope of 3 to 5%.
[0011] A sunken green space is provided above the rammed earth layer outside the buried scattered water layer. The height of the upper surface of the sunken green space is lower than the height of the upper surface of the planting soil layer, and the height difference is at least 100 mm.
[0012] The thermal insulation layer is a polyethylene foam board; the waterproof coating is composed of polymer cement mortar.
[0013] The outer ends of the pebble grouting mortar layer and the C20 fine stone concrete layer are both sloped at 40 to 50 degrees.
[0014] An overflow pipe is provided in the sunken green space, the mouth of the overflow pipe is 50 mm higher than the upper surface of the sunken green space, and crushed pebbles are filled around the mouth of the pipe.
[0015] A grate is provided above the pipe opening.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1) The water dispersion structure of the present invention includes a rammed earth layer, a buried water dispersion layer, and a planting soil layer.

[0018] 2) The exterior wall of the building of the present invention includes a foundation beam and a brick wall. The ends of the pebble-cast mortar layer and the C20 fine stone concrete layer are sequentially arranged on the horizontal part of the "L"-shaped foundation beam, which can increase the water path, facilitate water dispersion, and make the foundation less susceptible to erosion; the bottom end of the brick wall is in contact with the C20 fine stone concrete layer, which can improve the thermal insulation and waterproof effects. Coupled with the protection of the thermal insulation layer and the waterproof coating, the building has a strong ability to avoid water damage.
[0019] 3) The utility model is equipped with a sunken green space and an overflow pipe. If the rainfall is heavy, the sunken green space can collect rainwater and discharge it from the overflow pipe to avoid affecting the foundation of the building. BRIEF DESCRIPTION OF THE DRAWINGS
