Description

Technical Field

[0001] The utility model relates to the technical field of outdoor water dispersion construction, in particular to a novel combined construction structure of water dispersion and a finished drainage ditch. Background Art

[0002] Splashwater refers to a slope with a certain slope built at the footing around the exterior wall of a building. Commonly used materials include concrete, stone slabs and blocks. Splashwater can quickly drain rainwater around the exterior wall of a building to prevent rainwater from accumulating and seeping into the foundation, causing foundation sinking. Splashwater is often constructed in combination with finished drainage ditches, thus having the functions of both rainwater discharge and collection: rainwater around the exterior wall of a building is discharged from the splashwater to the finished drainage ditch connected side by side with the splashwater, and the finished drainage ditch discharges the collected rainwater into the drainage network.

[0003] However, in actual construction, the splash water and the finished drainage ditch are constructed separately and then connected by pouring splash water concrete. This construction method is simple and convenient, but due to the different materials used for the splash water and the finished drainage ditch, uneven settlement is very likely to occur after long-term use, resulting in cracks and water ingress at the connection points between the two, and deformation and cracking of the finished drainage ditch. In addition, in this construction combination, there is a gray soil layer under the splash water, which is equivalent to having only a single waterproof barrier line, the splash water surface, with weak waterproof ability, and rainwater is easy to seep in, and collapse is very likely to occur after long-term use.

[0004] Therefore, it is necessary to invent a new type of combined construction structure of a water dispersion and a finished product drainage ditch to overcome the defects of the current combined construction method of water dispersion and a finished product drainage ditch, which is prone to uneven settlement and weak waterproofing ability. Utility Model Content

[0005] The utility model provides a novel combined construction structure of a water sprinkling and a finished drainage ditch to overcome the defects of uneven settlement and weak waterproofing ability in the current combined construction method of a water sprinkling and a finished drainage ditch.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A new type of combined construction structure of scattered water and finished drainage ditch, comprising a building wall waterproof layer and an external wall insulation layer installed on the right side of the building wall waterproof layer; and also comprising an L-shaped scattered water surface layer cast on the right side of the external wall insulation layer;

[0008] A concrete cushion layer is poured at the bottom of the external wall insulation layer, and the bottom of the vertical section of the L-shaped splash surface layer is connected to the concrete cushion layer; the space enclosed by the external wall insulation layer, the L-shaped splash surface layer and the concrete cushion layer is filled with a lime soil backfill layer;

[0009] A finished drainage ditch is installed on the concrete cushion layer, and the finished drainage ditch is closely arranged on the right side of the vertical section of the L-shaped dispersion surface layer.

[0010] Furthermore, the surface where the L-shaped water dispersion surface layer meets the external wall insulation layer, and the surface where the L-shaped water dispersion surface layer meets the finished drainage ditch are coated with silicone weather-resistant adhesive sealing strips.

[0011] Furthermore, the left end of the concrete cushion layer is connected to the outer side surface of the building wall waterproof layer.

[0012] Furthermore, the concrete cushion layer is a slope layer; the right end of the concrete cushion layer exceeds the right end of the finished drainage ditch.

[0013] The structural design of the utility model is reasonable and reliable. A concrete cushion layer and an L-shaped splash surface layer connected to the concrete cushion layer are provided, which can effectively prevent uneven settlement of the L-shaped splash surface layer and the finished drainage ditch. At the same time, compared with the current combined construction method of splashing and finished drainage ditch, the vertical section of the L-shaped splash surface layer and the connection between the bottom of the vertical section of the L-shaped splash surface layer and the concrete cushion layer in the utility model can play a certain degree of waterproofing effect, and the waterproof ability is significantly enhanced. In addition, the added silicone weather-resistant adhesive sealing strip can further block rainwater leakage. BRIEF DESCRIPTION OF THE DRAWINGS
