Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of urban construction, and particularly relates to a hidden rainwater well cover of a sponge city pervious concrete and a construction method BACKGROUND

[0002] As a new generation of urban rainwater management concept, a sponge city refers to the excellent flexibility of a city in adapting to environmental changes and coping with natural disasters caused by rainwater. The concept can also be referred to as a "water-resilient city". Specifically, a city has significant "flexibility" in environmental adaptability and natural disaster response, which is commonly referred to as "low-impact development rainwater system construction" internationally. During rainfall, a city can perform water absorption, water storage, water penetration and water purification functions, and release stored water resources for use when necessary, so as to realize the free flow of rainwater in the urban space.

[0003] In municipal road engineering and outdoor auxiliary construction, rainwater well covers are widely used as an indispensable building material. At present, ductile iron well covers have become the mainstream choice due to their excellent performance, and their installation method is mainly exposed. However, there are certain difficulties in the connection of ductile iron well covers with pervious asphalt roads and pervious concrete, which limits their application in new pervious asphalt roads and pervious concrete roads. In order to meet the aesthetic requirements, rainwater well covers are usually placed under new pervious asphalt roads and pervious concrete roads. However, traditional rainwater well covers do not have the function of water permeability, so the development of pervious concrete well covers becomes the key to solving this problem. In addition, although pervious asphalt roads and pervious concrete roads can effectively block large foreign matter and garbage from entering the sewer, they are difficult to intercept fine sand particles carried in the water flow, which leads to the gradual accumulation of these particles on the surface of the well cover, thereby reducing the water permeability of the drainage well cover. This phenomenon needs to be solved by regular manual cleaning, which increases the complexity of maintenance. SUMMARY

[0004] In order to solve the problem that the traditional well cover cannot effectively intercept the sand carried in the water flow under the pervious concrete layer, and the sand accumulates on the inner surface of the well cover after interception, and frequent manual cleaning is required, the present application provides a hidden rainwater well cover of a sponge city pervious concrete and a construction method to solve the above problems.

[0017] Further, a sealing strip is arranged at the connection between the hidden well circle and the well seat, and the upper part of the hidden well circle can be electroplated with color.

[0018] Further, the recess arranged at the center of the hidden well circle is internally filled with asphalt, water permeable concrete or pebble material.

[0020] Further, the well seat, the hidden well circle, the pull holes and the steel bottom net are all made of metal material with certain strength, and have certain strength to meet the design vehicle load requirements.

[0021] Further, the well seat can be factory-produced, and the well mouth can be mass-produced according to common sizes DN900, DN800 and DN600, or can be customized according to design requirements.

[0022] Further, the recessed part of the hidden well circle can be filled with asphalt, water permeable concrete or pebble, and can be applicable to various scenes.

[0023] Further, when the water permeable hidden rainwater well cover is used in urban roads, the recessed part of the hidden well circle can be filled with asphalt surface layer to improve the comfort of drivers and ensure the overall visual effect.

[0024] Further, when the water permeable hidden rainwater well cover is used in road surface construction with water permeability requirements, the recessed part can be filled with water permeable materials such as water permeable concrete and water permeable asphalt, which can improve the visual quality and driving comfort, and the water permeable hidden rainwater well cover can assist in collecting and discharging rainwater, preventing road waterlogging and relieving urban waterlogging.

[0025] Further, when the water permeable hidden rainwater well cover is used in green landscape construction, the recessed part can be filled with pebble and other particle materials to ensure the visual quality while achieving rainwater collection, permeation and discharge.

[0026] Further, the hidden well circle can be electroplated with color to distinguish different functional wells and meet various use requirements.

[0030] The fluid diode reduces the flow resistance in one direction and increases the flow resistance in the opposite direction by designing a unique micro-nano structure, and the two are perfectly combined without interfering with each other, realizing long-distance self-driven transmission of liquid.

[0031] The water flow penetrating the pervious concrete layer is guided by the upper well cover and flows into the groove in the center of the hidden well circle, and then drips into the flow channel. Under the action of the fluid semiconductor, the water flow spontaneously flows along the flow channel and gradually collects into a larger water flow. When the water flow flows in the flow channel, it washes the flow channel, and at the same time, the height difference between the inner and outer layers of the flow channel forms an effective water flow washing effect, ensuring uniform distribution of the sand and preventing the sand from accumulating in a specific area. This design helps to prolong the overall cleaning period and the service life of the well cover. Finally, the water flow carrying the sand flows into the rainwater well through the metal mesh. After long-term use, the metal mesh may accumulate sand, at which time the staff only needs to start the rotating motor in the adjacent control room to drive the cleaning arm to perform cleaning work, thereby removing the sand attached to the lower surface of the well cover. This process further prolongs the interval time of manual cleaning and improves the overall maintenance work efficiency.

[0032] A construction method of a sponge city pervious concrete hidden rainwater well cover, comprising the following steps:

[0033] S1, according to the drawing requirements, the corresponding specification and model of the inspection well are made, and each inspection well is assembled according to the drawing;

[0035] Before the road surface layer construction, the hidden well circle is placed in the rebate inside the well seat, and the hidden well circle is tightly attached to the well seat without loosening;

[0036] S3, a1: when used in landscape, green engineering, the concave part of the hidden well ring is filled with pebble material; the concave part of the hidden well ring should be constructed together, the internal filler of the well ring is consistent with the material used in the road surface, and manual paving and mechanical compaction should be used during paving to ensure the flatness of the road surface;

[0037] a2: when the whole rainwater well is covered by the road surface, first install the partition plate and the flow splitter in the hidden well ring, and then install the well lid, and then pave the road surface after installation is completed.
