Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage, in particular to a concrete drainage structure based on an urban drainage system. Background Art

[0002] Concrete drain pipes are pipes used in drainage systems, usually made of concrete, to collect and discharge rainwater or sewage. Such drain pipes are often used in urban roads, buildings and other places to effectively manage and direct water flow and prevent water soaking and accumulation. Sponge city is an urban planning and construction concept that aims to minimize rainwater runoff and incorporate rainwater into urban ecosystems for utilization by mimicking the principles of natural ecosystems. The drainage system of sponge cities includes a variety of measures, such as green roofs, permeable pavement, rain gardens, wetland parks, etc., as well as reasonably designed rainwater collection and discharge facilities. Concrete drain pipes play an important role in the drainage system of sponge cities. They can be used in combination with other drainage facilities in sponge cities, such as rain gardens, wetland parks, etc., to build a complete and sustainable drainage system. At the same time, concrete drain pipes themselves can also help achieve effective collection and discharge of rainwater by designing reasonable slopes and layouts, and equipping them with appropriate filtering equipment. In sponge cities, the design and use of concrete drain pipes need to take into account their interaction with natural ecosystems and their impact on the environment. They not only need to have the functions of traditional drainage pipes, but also need to pay more attention to coordination with the surrounding environment to maximize the utilization of rainwater resources, protect the ecological environment, and enhance the resilience and sustainable development capabilities of the city.

[0003] The prior art has the following problems:

[0004] The existing concrete drainage structure based on the urban drainage system has two traditional drainage methods: point drainage and linear drainage. Point drainage is to set a rainwater inspection well at a certain distance on the ground. The inspection well collects surface rainwater and flows it into the underground drainage network. Its disadvantage is that when encountering severe weather such as heavy rain, it is impossible to collect surface rainwater in time and in sufficient quantity, thus forming waterlogging; linear drainage is to set drainage ditches of different materials on the surface to collect surface rainwater and flow it into the underground drainage network. Although this method can solve the shortcomings of point drainage, it has a relatively high construction cost due to the configuration of various covers (grates) of different materials. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a concrete drainage structure based on an urban drainage system to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete drainage structure based on an urban drainage system, comprising a drainage structure main body, a drainage pipe is fixedly installed inside the drainage structure main body, a drainage cavity is arranged inside the drainage pipe, a water collection port is arranged on the top of the drainage structure main body, a water inlet is arranged inside the water collection port, and a stainless steel grate is arranged on the top of the water collection port.

[0007] As a preferred technical solution of the utility model, the inner wall of the main body of the drainage structure is provided with reinforcing ribs.

[0008] As a preferred technical solution of the utility model, the drainage pipe runs through the interior of the drainage structure body.

[0009] As a preferred technical solution of the utility model, a plurality of water inlet holes are provided, and the water inlet holes are evenly and symmetrically distributed on the top of the water collection port, and the water inlet holes are connected to the drainage pipe.

[0010] As an optimal technical solution of the utility model, the stainless steel grate includes a water filter port and a slot. The top of the stainless steel grate is provided with a water filter port, the bottom of the stainless steel grate is provided with a slot, and there are several water filter ports, which are evenly and symmetrically distributed on the stainless steel grate.

[0011] As a preferred technical solution of the utility model, the size and position of the water filter port correspond to the water inlet hole.

[0012] As a preferred technical solution of the utility model, the inner diameter of the slot is matched with the outer diameter of the water collection port, and the stainless steel grate is movably connected with the water collection port through the slot.

[0013] Compared with the prior art, the utility model provides a concrete drainage structure based on the urban drainage system, which has the following beneficial effects:

[0014] 1. This concrete drainage structure based on the urban drainage system, the height of the water collection port of this application can be adjusted arbitrarily within a certain range. First, it can meet the design requirements of different heights of the slotted stainless steel cover plates on the traditional drainage ditch. Second, it can meet the design requirements of different loads. The greater the height of the water collection port, the thicker the C25 concrete or C30 concrete layer poured on both sides of the linear water collection port, and the higher the bearing capacity; third, it effectively reduces the cost of the cover plate. Although stainless steel or cast iron grates are also required on the upper part of the water collection port of this product, the cost is relatively low because the water collection port of this product is very narrow and the consumables are small.

[0015] 2. This concrete drainage structure based on the urban drainage system, the water collection port of this application can be adjusted to be high at one end and low at the other end, which can effectively solve the slope problem in engineering construction. This application is equipped with rainwater inspection wells of various specifications and models, which can smoothly flow the surface rainwater collected by the drainage pipe into the underground drainage network. This application can effectively avoid the defects of point drainage and linear drainage through structural design, and can give play to the common advantages of both. At the same time, this application has the common functions of linear drainage ditches and branch drainage pipes. BRIEF DESCRIPTION OF THE DRAWINGS
