Detailed Description
The application is described in further detail below with reference to fig. 1-3.
The embodiment of the application discloses an ecological grass planting ditch for gardens.
Referring to fig. 1, the ecological grass planting groove for gardens includes a groove 1 and slope protection 2 disposed at both sides of the groove 1 in an inclined manner. The inside that is located slot 1 has set gradually plain soil tamp layer 11, gravel drainage layer 12, first geotechnique cloth layer 13, sand layer 14, second geotechnique cloth layer 15, planting soil layer 16, diapause layer 17 and vegetation layer 18 from bottom to top, and vegetation layer 18 comprises one or more of green grass, slide rail, bush. The roots of the plants used in the vegetation layer 18 penetrate into the interior of the planting soil layer 16.
The slope protection 2 is provided with a protecting foot 3 at the slope foot, and the protecting foot 3 is formed by piling pebbles. When rainwater flows into the groove 1 along the slope protection 2, the feet 3 can block soil left with water, and the water can flow through gaps among pebbles, so that the water flows to the upper side of the stagnant water layer 17.
Referring to fig. 1 and 2, a plurality of vertically arranged installation pipes 4 are further arranged in the groove 1, the inside of the re-planted soil layer 16 is pre-buried and fixed by the installation pipes 4, and the top pipe orifice of the installation pipes 4 is exposed from the top end face of the stagnant water layer 17. The bottom end of the installation tube 4 pierces the second geotextile layer 15 so as to be inserted into the interior of the sand layer 14.
The inside of the installation tube 4 is provided with a vertically arranged drain pipe 5, and the drain pipe 5 is inserted into the inside of the installation tube 4 and is clamped in the inside of the installation tube 4. The top end of the drain pipe 5 is higher than the top end face of the stagnant water layer 17 so as to leave a distance from the top end face of the stagnant water layer 17. The height of the top end of the drain pipe 5 can be determined according to the height of the plant selected in the vegetation layer 18 and the water demand of the plant.
In the case of rainy weather, when the water level of water above the stagnant water layer 17 is higher than the top nozzle of the drain pipe 5, the water higher than the drain pipe 5 is introduced into the inside of the sand layer 14 along the drain pipe 5. The rainwater entering the sand layer 14 is firstly filtered by the sand layer 14, the water filtered by the sand layer 14 passes through the first geotextile layer 13 and then flows into the gravel drainage layer 12, and finally is discharged through the gravel drainage layer 12. The water below the top nozzle of the drain pipe 5 remains above the stagnant water layer 17. When water flows into the gravel drainage layer 12 along the drainage pipe 5, the drainage of water above the stagnant water layer 17 can be quickened, and the time for plants in the vegetation layer 18 to be submerged in the water can be reduced.
Referring to fig. 1 and 2, a plurality of first water penetration holes 41 are formed in a position where the pipe wall of the installation pipe 4 is opposite to the planting soil layer 16, and the first water penetration holes 41 are arranged at intervals along the circumferential direction of the installation pipe 4. The outer side surface of the pipe wall of the installation pipe 4 is provided with a fork 42 which extends outwards, and the fork 42 and the installation pipe 4 are integrally formed. The forked thorns 42 are arranged in a staggered manner with the first water seepage holes 41.
The outside of the installation tube 4 is further provided with a filter cloth 6 wrapping the installation tube 4 inside. The filter cloth 6 wraps the first water penetration holes 41 of the installation tube 4 inside. The prongs 42 pierce the filter cloth 6 so as to be exposed from the outer side surface of the filter cloth 6. When the mounting pipe 4 is pre-buried in the planting soil layer 16, the mounting pipe 4 can be firmly fixed in the planting soil layer 16 due to the presence of the fork thorns 42.
The outer diameter of the drain pipe 5 is smaller than the bore diameter of the mounting pipe 4. The side wall of the drain pipe 5 is provided with a plurality of second water penetration holes 51 spaced apart along the circumferential direction of the drain pipe 5. An elastic claw 52 extending to the outer side of the pipe wall of the drain pipe 5 is arranged at the inner top end of the second water seepage hole 51, and the elastic claw 52 and the drain pipe 5 are integrally formed. The elastic claw 52 is provided obliquely in the bottom end direction of the drain pipe 5. The number of the second water penetration holes 51 is the same as that of the first water penetration holes 41, and the included angle between the axes of two adjacent second water penetration holes 51 is the same as that between the axes of two adjacent first water penetration holes 41.
When the drain pipe 5 is inserted into the installation pipe 4, the elastic claw 52 is in a pressed state when the elastic claw 52 enters into the inner hole of the installation pipe 4, and the elastic claw 52 is clamped into the corresponding first water penetration holes 41 when the second water penetration holes 51 of the drain pipe 5 are opposite to the first water penetration holes 41 on the installation pipe 4 one by one. When the elastic claw 52 is clamped into the first water seepage hole 41, a gap for water to pass through is reserved between the elastic claw 52 and the wall of the first water seepage hole 41.
Referring to fig. 1 and 3, a cylindrical valve core 7 is slidably connected to the inside of the drain pipe 5, and the cylindrical valve core 7 is vertically arranged. The inside of the cylindrical valve core 7 is provided with a drain hole 71 communicating with the bottom end surface of the cylindrical valve core 7, and the top side wall of the cylindrical valve core 7 is provided with a water inlet hole 72 communicating the drain hole 71 with the side wall outer surface of the cylindrical valve core 7. The top end of the cylindrical valve core 7 is fixed with a floating ball 73, and the diameter of the floating ball 73 is larger than the top end pipe orifice of the drain pipe 5. When the water level is lower than the top pipe orifice of the drain pipe 5, the cylindrical valve core 7 is under the action of gravity, and the floating ball 73 seals the top pipe orifice of the drain pipe 5. When the water level is higher than the drain pipe 5, the floating ball 73 floats with the increase of the water level, and pulls the cylindrical valve core 7 to move upwards until the water inlet hole 72 moves out of the top pipe orifice of the drain pipe 5.
When the water inlet hole 72 is higher than the top nozzle of the drain pipe 5, water flows into the inside of the drain hole 71 along the water inlet hole 72, and finally flows into the inside of the drain pipe 5.
The inside that is located sand bed 14 and the below of every drain pipe 5 have all been pre-buried fixed block 8, link to each other through flexible cotton rope 9 between fixed block 8 and the cylinder case 7, and cotton rope 9 one end is fixed with fixed block 8, and the other end and the cylinder case 7 of cotton rope 9 are fixed. When the rope 9 is in a straightened state, the bottom end of the cylindrical valve core 7 is positioned in the inner hole of the drain pipe 5.
The implementation principle of the ecological grass planting ditch for gardens in the embodiment of the application is as follows: when the water level of the water which is gathered into the grass planting ditch is higher than the water draining pipe 5, the water flows into the sand layer 14 from the water draining pipe 5 and flows downwards along the sand layer 14 until flowing into the gravel water draining layer 12, finally flows out along the gravel water draining layer 12, the water is quickly drained into the gravel water draining layer 12 through the water draining pipe 5 and filtered through the sand layer, so that the water level above the water retaining layer is quickly lowered, and the time for plants in the vegetation layer to submerge in the water is reduced.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
