Technical Field
The invention relates to the technical field of sponge city drainage, in particular to a drainage ditch system of a sponge city.
Background
Drainage ditches are currently installed in devices for draining accumulated water, such as houses, highways, construction sites, etc. The setting to the escape canal among the urban construction does not carry out careful design, generally adopts open drain drainage, adopts the brick to build and plasters the setting that carries out the escape canal. However, in heavy rain, municipal pipelines and corresponding water collecting systems cannot bear excessive rainwater under the condition of excessive drainage, so that rainwater is irrigated in a flood mode, and very adverse consequences are caused to various fields. In a traditional drainage ditch system, the phenomena of different losses caused by overlarge flow of rainwater in unit time in parks, municipal roads, construction sites and the like often occur. Therefore, it is urgently needed to develop a drainage ditch system to solve the problem of flood irrigation caused by the upper limit of the load of the drainage system in rainy season.

Detailed Description
The following examples are provided to further illustrate the present invention for better understanding, but the present invention is not limited to the following examples.
Referring to fig. 1, the invention provides a drainage ditch system of a sponge city, which comprises a ditch, a plant layer and an interlayer. When the trench is dug, the bottom of the trench is ensured to be lower than the water inlet of the municipal pipeline 1 or the water collecting well 2. After the trench is excavated, the sand-lime bricks 3 are laid on the two opposite side walls of the trench, so that the stability of the trench is ensured. The plant layer 4 is planted in the soil layer 5 at the bottom of the groove, in order to ensure the normal growth of the plant layer 4, the plant layer 4 is vegetation which likes the dark and humid environment, and the early-stage maintenance is carried out after the plant layer 4 is planted, so that the vegetation grows normally. The presence of the plant layer 4 protects the soil structure at the bottom of the trench from soil silting due to rain wash.
Referring to fig. 2 and 3, the interlayer is connected with the water inlet of the municipal pipeline 1 or the water collecting well 2 and comprises a bulge 60 and connecting parts 61 respectively connected with the bottom ends of the two sides of the bulge 60. In the present embodiment, the protrusion 60 has a trapezoidal shape, but may have other shapes in other embodiments, such as a U-shape, and the connecting portion 61 has a zigzag shape. The connection portion 61 is connected to the bottom end of the protrusion portion 60 to form a drain groove 62 through which water flows. In order to ensure the stability of the insulation, the connecting part 61 is fastened to the sand lime bricks 3, so that the insulation is firmly fixed to the sand lime bricks 3. A certain distance is reserved between the bottom of the installed interlayer and the bottom of the groove, so that a self-absorption drainage layer 63 capable of absorbing excessive water when rainfall is large is formed between the interlayer and the bottom of the groove. In order to facilitate the drainage pressure of the municipal pipeline 1 or the water collecting well 2 to be reduced when the water quantity is large, water can flow into the self-absorption drainage layer 63, a plurality of water inlet holes 64 for water to flow into are formed in the top surface of the protruding portion 60, so that when the rainfall is too large, rainwater flows over the protruding portion 60 and is drained down to the self-absorption drainage layer 63 through the water inlet holes 64 to be absorbed, the unit drainage quantity is controlled by the water inlet holes 64, and most of door impurities can be screened out to prevent the rainwater from entering the self-absorption drainage layer 63. In order to prevent that soil in the slot from entering into municipal pipeline 1 or sump pit 2, at the vertical stagnant water layer 7 that is provided with downwardly extending of interlayer and municipal pipeline 1 or sump pit 2's junction, this stagnant water layer 7 carries out the shutoff with soil layer 5 of self-absorption drainage blanket 63 and slot bottom, because this self-absorption drainage blanket 63 is kept apart outside municipal pipeline 1 or sump pit 2, consequently, the inside ponding of self-absorption drainage blanket 63 and soil can not get into municipal pipeline 1 or sump pit 2, the corresponding product of sump pit 2 and municipal pipeline 1 has been alleviated, the drainage ability, thereby reach the purpose of self-absorption. In addition, the drainage grooves 62 have a certain installation gradient, and particularly, the drainage grooves 62 are inclined downwards towards the municipal pipeline 1 or the water collecting well 2, so that rainwater can be conveniently drained into the water collecting well 2 or the municipal pipeline 1 through the drainage grooves 62 on the two sides of the interlayer. In order to facilitate later maintenance, the interlayer is spliced and erected and is made of waterproof hard materials.
In the case of applying the drainage ditch system of the present embodiment, as shown in fig. 4, in a rainy day, rainwater is drained to the municipal pipeline 1 or the water collecting well 2 through the drainage grooves 62 formed by the protrusions 60 and the connecting portions 61 of the partition, and a part of the rainwater vertically falls down to enter the lower self-absorbing drainage layer 63 through the water inlet holes 64 to be absorbed by soil. And when heavy rain falls, as shown in fig. 5, rainwater in the interlayer is drained into the corresponding water collecting well 2 or municipal pipeline 1 through the drainage grooves 62, but because the water level of the drainage grooves 62 on both sides of the interlayer is increased due to excessive rainfall, the increased rainwater overflows the protruding part 60 and then leaks to the lower self-absorption drainage layer 63 through the middle water inlet 64, is absorbed and digested in the self-absorption drainage layer 63, and because of the existence of the water stop layer 7, the self-absorption drainage layer 63 is isolated outside the municipal pipeline 1 or the water collecting well 2, so that accumulated water and soil in the self-absorption drainage layer 63 cannot enter the municipal pipeline 1 or the water collecting well 2, and the corresponding product and drainage capacity of the water collecting well 2 and the municipal pipeline 1 are relieved. In addition, due to the water inlet holes 64 and the self-absorption drainage layer 63, rainwater in the interlayer can be at a controllable height, time can be provided for pumping and drainage after water is accumulated in the water collecting well 2, the problem of flood irrigation caused by overlarge rainfall is solved, the receiving capacity of the municipal pipe network is relatively enlarged, and the water inflow in unit time is controlled.
While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
