Description
Technical Field
[0001] The invention relates to the technical field of building waterproofing, and in particular to a concealed concrete water dispersion structure. Background Art
[0002] Diffusers refer to the protective layer laid around the building to prevent rainwater and water for production and life from seeping in. The purpose of setting up diffusers is to allow the ground water near the footing of the building's outer wall to be drained away quickly, and to prevent the dripping water from the eaves from eroding the soil around the outer wall, reduce the possibility of water soaking of the wall and foundation, protect the wall and foundation, and extend the life of the building.
[0003] At present, the surface of the scattered water is cast with cement mortar or concrete with a certain slope. The singleness of the exposed surface color and the uniqueness of the function cannot meet the needs of development. Matching some green plants or landscapes around the buildings where people live or move can not only increase 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 to beautify the environment. Summary of the invention
[0005] The present invention provides a concealed concrete water dispersion structure, in which a concealed water dispersion layer can effectively drain ground water near an 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 object, the present invention adopts the following technical solutions:
[0007] A concealed concrete splash water structure, which is arranged around the foundation of the outer wall of a building; the splash water structure includes, from bottom to top, a rammed earth layer, a concealed splash water layer and a planting soil layer; the concealed splash water layer includes, from bottom to top, a pebble pouring mortar layer, a C20 fine stone concrete layer and a waterproof geotextile layer; the pebble pouring 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 arranged on the outer side of the outer wall of the building, and a waterproof coating is arranged on the outer side of the insulation layer; a caulking paste is arranged 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 3-5%.
[0011] A sunken green space is arranged above the rammed earth layer outside the buried scattered water layer, and 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 pouring mortar layer and the C20 fine stone concrete layer are both sloped at 40 to 50 degrees.
[0014] An overflow pipe is arranged 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 arranged above the pipe opening.
[0016] Compared with the prior art, the present invention has the following beneficial effects:

[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 and facilitate water dispersion, making 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. In addition, 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 present invention is provided 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
