Description

Planting roof vegetation layer oozes drainage system

Technical Field

The invention relates to a vegetation layer drainage facility, in particular to a seepage drainage facility comprising a garage top plate and a house top plate vegetation layer.

Background

The existing vegetation greening of building roofs including underground garages, overground houses and the like is to lay soil layers on the roofs, and plant flowers, plants and trees on the soil layers. In order to ensure the discharge of the excessive moisture of the soil layer and the vegetable layer, a drainage plate is usually laid between a top plate and the soil layer, and the excessive moisture of the soil layer and the vegetable layer downwards seeps to the drainage plate under the action of natural gravity and is discharged through a flow channel of the drainage plate. The geotextile is laid on the drainage plate to prevent soil from falling to block a flow channel of the drainage plate. The arrangement is feasible in the non-heavy rain and heavy rain periods, but when heavy rain is encountered for a long time, particularly heavy rain, heavy rain and extra-heavy rain, a large amount of accumulated water in the soil layer and the vegetation layer cannot be discharged in time, the normal growth of the vegetation layer is influenced, and other environmental and ecological damages can be caused.

Furthermore, a guide pipe is connected below the overflow filter.

And further, a drainage plate is arranged at the corresponding position of the lower end of the seepage pipe, and geotextile B is laid on the drainage plate.

And furthermore, the lower end of the flow guide pipe is connected with a permeated water collecting pipe.

Preferably, the overflow filter has a water inlet top cover and a bottom sleeve, the water inlet top cover and the bottom sleeve are connected through a hinged shaft, a water inlet grid hole is formed in the water inlet top cover, the bottom sleeve is provided with an upper cavity body and a lower cavity body which are integrally connected and vertically communicated, a sleeve hole extending on the hole wall is formed in the bottom of the lower cavity body, and the upper end part of the flow guide pipe is internally sleeved with the sleeve hole.

Preferably, the upper surface of the trepanning is connected with a water passing supporting top.

Furthermore, the upper cavity of the bottom sleeve is internally provided with a filtering pocket, gravels are placed in the filtering pocket, a geotextile C is arranged between the gravels and the inner wall of the filtering pocket, and a geotextile D is arranged on the water passing supporting top.

The planting roof plate refers to a roof plate of buildings such as an underground garage and an overground house, and a vegetation layer can be arranged on the roof plate.

According to the planting top plate vegetation layer, the drainage plate is laid on the top plate, the geotextile is laid on the drainage plate, the soil layer is laid on the geotextile, and the vegetation layer on the soil layer is used for planting flowers, plants and trees. The excessive water in the vegetable layer and the soil layer can be infiltrated to the drainage plate and discharged. The present invention is applied to this occasion.

The overflow filter is installed corresponding to the surface of the soil layer, the upper opening of the overflow filter corresponds to the vegetation layer, and the lower opening of the overflow filter is embedded into the soil for a certain distance. The seepage pipe is sleeved on the periphery of the overflow filter, and the seepage pipe extends downwards to reach the geotextile on the drainage plate. The pipe wall of the seepage pipe is wrapped with geotextile A, so that soil is prevented from blocking the water through holes, and water in the soil layer can seep into the seepage pipe and flow down to the drainage plate.

The seepage pipe with the relatively small diameter is suitable for sandy soil layers, and water in the soil layers can seep into the seepage pipe from the lateral direction. The infiltration pipe with the relatively large diameter is suitable for the cohesive soil layer, because water in the cohesive soil layer is not easy to enter the infiltration pipe from the lateral seepage, so that broken stones are filled in the infiltration pipe with the relatively large diameter, geotextile is paved on the broken stones, and moisture on the vegetable layer and the shallow surface layer of the soil layer seeps from top to bottom and flows down to the drainage plate through the broken stones.

The seepage pipe is arranged on the periphery of the overflow filter, water in a soil layer can laterally enter the seepage pipe to be discharged, and the soil layer seepage pipe is particularly suitable for draining sandy soil layers. The infiltration pipe can be the diameter relatively big, also can be the diameter relatively little, and the infiltration pipe that the diameter is relatively big is filled with the rubble in the infiltration pipe intussuseption, has spread geotechnological cloth above the rubble, and the water on vegetable layer, soil horizon top layer can fall into from top to bottom, and it is discharged through the downward flow of rubble layer, and it is particularly suitable for viscidity soil layer, and because of the water on viscidity soil layer oozes the speed of flowing into the infiltration pipe slowly from the side direction, and top-down falls into the infiltration pipe and then discharges through the rubble layer relatively fast. The invention can accelerate the water seepage and drainage in the soil layer and ensure the excessive water in the soil layer and the vegetable layer to be drained in time due to the seepage pipe.

The invention is further described with reference to the following figures and detailed description.
