Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

The strong drainage system 100 for stadiums comprises a plurality of underground drainage structures 1 laid under the stadium, the sum of the drainage areas of all the underground drainage structures 1 is equal to the area of the stadium, each underground drainage structure 1 comprises a plurality of drainage pipelines laid under the ground and a strong drainage pump connected with the drainage pipelines and used for enhancing the drainage effect, each drainage pipeline is provided with an independent drainage port communicated with an external main drainage pipe 2, and each drainage pipeline is a drainage pipe with water seepage or water leakage function. This scheme sets up through the aforesaid, divide the stadium into a plurality of regions and lay independent drainage pipe, when needs drainage, the accessible starts the forced drainage pump that corresponds the region and makes the pipeline form negative pressure environment, alright quick realization carries out independent accurate forced drainage to certain region of stadium, this kind of mode not only can make the drainage more high-efficient, and because every regional ponding degree is different, only need open the forced drainage pump in certain several regions and just can make the place can satisfy the needs of the race, it is more intelligent energy-conserving to drain water.

The drainage system of the scheme is not only suitable for stadiums, but also can be applied to golf courses or other green places, and the function of forced drainage of each application place accurate area can be realized after adaptive modification is carried out on different places.

Meanwhile, the underground drainage structures 1 in each area are independent, namely, each underground drainage structure 1 is connected with the external main drainage pipe 2, so that accumulated water in each area can be directly drained from the external main drainage pipe 2 when forced drainage is carried out, other areas do not need to flow through, drainage efficiency is improved, and the problem that drainage is influenced by the fact that drainage pipelines are occupied by other areas when the accumulated water flows through the other areas is avoided.

The division of region can divide regional shape, size and figure according to the actual conditions (ponding degree, frequency of use etc.) in this scheme, and this scheme does not do the restriction to regional shape, size and figure, and the shape of arranging (rectangle, circular, fan-shaped, fish bone shape etc.), structure, size and figure of drainage pipe can also arrange along with regional difference in a flexible way simultaneously. The above-described modifications are within the scope of the present disclosure without further modifications. In the embodiment, the stadium is preferably divided into ten independent areas, and each area is independently and directly connected to a main drainage pipeline of the stadium to realize a traditional drainage function; meanwhile, each area can be independently controlled to be one area. The advantage of such a design is not only the general drainage function; more importantly, when forced venting is required, the equipment requiring forced venting does not require significant power. By dividing the field, the requirement on equipment supply is greatly reduced, and the method is more economical and has higher efficiency. In addition, partition control can be realized, and accurate management can be achieved.

Preferably, wherein the shape in every region is the rectangle, drainage pipe includes that a plurality of drainage branch pipes 11 surround the rectangle drainage frame that regional edge constitutes and be parallel interval set up in a plurality of drainage branch pipes 11 in the rectangle drainage frame, drainage branch pipes 11 all communicate with each other, wherein rectangle drainage frame be equipped with forced-ventilated pump interface 12 that forced-ventilated pump is connected, forced-ventilated pump interface 12 extends to ground from the underground and is connected with forced-ventilated pump, constitutes independent drainage system in an area from this.

Preferably, forced-ventilated pump interface 12 in this scheme is extended to ground, and because dividing whole stadium in this scheme has reduced the working strength of forced-ventilated pump, therefore the forced-ventilated pump in this scheme is less type and portable (can also install the forced-ventilated pump outside the stadium equally, its area is also very little). When a certain area needs to be drained in a stadium, the underground drainage structures 1 connected to the area and corresponding to the forced drainage pumps can be pushed to realize forced drainage, one forced drainage pump does not need to be configured for each underground drainage structure 1 in each area, occupied space is saved, and meanwhile, a lot of cost is saved.

When strong drainage is carried out, the strong drainage pump is started to pump air from the strong drainage pump connector 12 so that the underground drainage structure 1 forms negative pressure (smaller than atmospheric pressure), at the moment, water permeating into soil also enters the drainage branch pipe 11 due to pressure, and finally accumulated water flows into the external main drainage pipe 2 under the combined action of self gravity and negative pressure. (the arrows in FIG. 2 are directed to the direction of flow of water in the underground drainage structure under the action of the forced displacement pump).

The branch drainage pipe in the scheme is a drainage pipe with water seepage or water leakage functions, wherein the branch drainage pipe can be a drainage pipe with a seepage hole and a drainage pipe with water seepage on the pipe wall. Preferably, the drain branch pipe 11 is a double-wall corrugated pipe with the infiltration hole, and the infiltration hole is arranged below the double-wall corrugated pipe. The double-wall corrugated pipe is a novel pipe with an outer wall of an annular structure and a smooth inner wall, the outer wall of the double-wall corrugated pipe is of an annular corrugated structure, the annular rigidity of the pipe is greatly enhanced, the resistance of the pipe to soil load is enhanced, and meanwhile, the smooth inner wall can reduce the friction coefficient and is larger than other pipe passing through the same caliber. Finally, the flexible layer has proper flexibility, and can be directly paved in the uneven groove without using a pipe connector.

The drainage of the stadium is mainly designed in two ways, one is surface drainage, and the other is gravity underground drainage; when the intensity of rainfall is greater than the soil infiltration speed, the moisture can not fully infiltrate the soil, runoff can be generated on the ground surface, and the runoff water flows into the drainage ditches around the field along the gradient of the field and is discharged. Part of rainwater also permeates into the soil and is drained through an underground drainage pipe; in order to increase the drainage efficiency of the gravity underground drainage mode, the drainage pipeline is obliquely arranged from the center of the stadium to the periphery, and the inclination of the inclination is 3-5 per mill (the specific inclination degree can be changed according to the specific adaptability of the applied stadium). When the intensity of rainfall equals or is less than soil infiltration speed, and when soil moisture content does not reach the field moisture capacity of soil, the earth's surface just can not produce the runoff, and the rainwater is all in the infiltration soil, and wherein partly is detained in soil, and another part forms gravity water and discharges through underground drainage pipe, and the drainage pipe design of slope can make the more rapid outside main drain pipe 2 of flow direction of rainwater.

Because the self shape structure of stadium is the tortoise back form, it is that the higher position all around of intermediate position is low promptly, therefore can know through foretell two kinds of drainage modes, and some ponding that is located the intermediate position can descend to ooze the drainage system that gets into this region underground, and still partly has flowed towards all around along with the relief from the earth's surface, therefore the ponding degree of intermediate position can be less than the ponding degree of all around region, to this embodiment the density that drainage pipe laid increases from stadium center to all around for the ponding of all around region can be fast the light emission. Meanwhile, the density of the drainage pipelines in each area can be adjusted according to the use frequency of the area, such as: the large forbidden zone range in the football field has high use frequency, the area is an activity area of a goalkeeper and is more intensively trampled, so the large forbidden zone can be independently divided into one area, the density of the drainage pipelines in the area can be higher than that of the drainage pipelines in other areas, accumulated water in the large forbidden zone can be quickly drained, and the requirement of a match is met.

In addition, when a large international event is held in a city with a high latitude, if the local climate of the city holding the event is cold, the growth of the lawn in the sports field may be affected at this time, so that the requirement of the event cannot be met. To this end, the underground drainage structure 1 in this embodiment further includes a temperature adjusting device communicated with the drainage pipeline and used for heating and cooling, so as to adjust the temperature of the root soil, provide an optimal growing environment for the growth of the lawn, enable the lawn to grow at an appropriate temperature, and ensure that the quality of the lawn can meet the requirements of the event in cold weather.

Preferably, the underground drainage structure 1 further includes a blowing device for blowing out gas in the soil. In the process of daily lawn maintenance, the drainage system can blow up the root layer to discharge harmful gas in the root layer soil, improve the lawn growth environment and maintain a high-quality stadium lawn. The air blowing device can be realized by the forced-ventilated pump, and the forced-ventilated pump is bidirectional, so that the air blowing function can be realized only by exchanging the interface of the forced-ventilated pump.

Through foretell, the drainage system of this scheme not only has the function of bleeding and forming the negative pressure forced drainage, still has the function that blows into the intrinsic harmful gas that blows off the root layer from the infiltration hole of entering drainage branch pipe 11 simultaneously, to this, this embodiment is preferred drainage pipe is equipped with aqueous vapor separation valve 13 with the junction of outside main drain pipe 2, and this aqueous vapor separation valve 13 can guarantee inclosed under the state of bleeding, makes the intracavity form negative pressure and takes unnecessary water out from the root layer, and the rethread main drain pipe 2 discharges. While in the aerated state allowing the aeration means to blow through the drain leg 11 into the root zone.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
