At the same time, its storage and drainage function can effectively use the rainwater runoff increased by urbanization to make road rainwater resources, and can also solve the shortage of urban water resources and pollution. question.

Description

Reinforced concrete or natural stone U-shaped filter trough curb

technical field

The utility model relates to a building component for paving, in particular to a reinforced concrete or natural stone U-shaped filter trough curb stone.

Background technique

With the development of urban construction and the improvement of road network, the urban ground hardening rate is getting higher and higher. The supply of groundwater is gradually decreasing, and it is necessary to use rainwater in the face of urban water shortage. It is more and more important for the development of the whole city to use urban roads to effectively collect surface runoff due to urban ground hardening and make rational use of it. Modern urban rainwater utilization is a new type of multi-objective comprehensive technology, which can achieve goals such as water conservation, water conservation and protection, control of urban soil erosion and waterlogging, reduction of water pollution, and improvement of urban ecological environment.

In the usual urban road design, curb stones are set on both sides of the separation strip, and the curb stones are generally 10-20cm higher than the edge of the roadway. Each goes its own way to ensure that the road has a higher traffic capacity and the safety of pedestrians is guaranteed. At the same time, it also plays a role in collecting and guiding the rainwater from the driveway and sidewalk to flow into the rainwater outlet along the longitudinal direction. For this treatment method, rainwater enters the river channel through the urban drainage pipe network, but does not make effective use of rainwater resources, causing a large amount of rainwater resources to flow away in vain. This is a great waste of resources for my country's water-deficient areas.

Utility model content

The purpose of this utility model is to provide a reinforced concrete or natural stone U-shaped filter trough curb for collecting, storing, dissipating and filtering rainwater, so as to solve the problem that the existing curb cannot store and filter rainwater.

The utility model achieves through the following technical solutions:

This reinforced concrete or natural stone U-shaped filter trough curb consists of an asymmetric U-shaped trough formed by an open-hole edge stone, an open-hole soil retaining board and a bottom plate. The water inlet hole, the side of the perforated earth retaining plate is horizontally arranged with drainage holes connected with the soil body, the rainwater flows into the longitudinal U-shaped groove through the horizontal water inlet hole along the transverse slope of the road surface, and passes through the filter material in the U-shaped groove The filtered rainwater is stored in the U-shaped tank and supplemented with groundwater, and the overflowed rainwater is discharged into the rainwater collection well.

The U-shaped groove is filled with filter materials, and the filter materials can be gravel, pebbles or other filter materials.

The utility model saves resources and has good environmental performance. Utilize urban pavement to collect rainwater and combine road drainage with rainwater utilization, which not only ensures the safety of urban flood control, but also alleviates road surface water and urban road water damage, and ensures smooth urban traffic. At the same time, its storage and drainage function effectively utilizes the increased rainwater runoff of urbanization, makes road surface rainwater a resource, and can also solve the problem of urban water resource shortage and pollution, thus playing a positive role in promoting the development of urbanization.

Prefabricated reinforced concrete or natural stone U-shaped filter trough curbs are generally assembled before the pavement structure is paved. They are prefabricated in the factory and transported to the site for assembly. The construction process is similar to ordinary curbs.

Although the cost of prefabricated components is higher than that of ordinary curbs, the cost of blind ditch and seepage pipe is greatly reduced.

The filter material in the U-shaped groove is easy to clean, and it is not easy to be blocked during use. Easy to clean even if clogged.

The prefabricated components are prefabricated and assembled, and the maintenance and repair are more convenient. It only needs to be dismantled and replaced during maintenance, and generally there is no need to excavate the pavement structure.

Detailed ways

Prefabricated reinforced concrete or natural stone U-shaped filter trough curbstones, composed of open-hole edge stone 1, open-hole retaining board 3 and bottom plate 5 to form asymmetrical U-shaped trough strips, each component is made of steel bars, cement, gravel and It can be made of sand or natural stone; the structure can be prefabricated as a whole, or it can be assembled and installed by decomposing prefabrication. The filter material 6 is filled in the U-shaped groove, and the filter material can be selected from crushed stones, pebbles or other filter materials.

The length of each U-shaped groove block is generally 59cm. There are 1 to 3 water inlet holes 2 for collecting rainwater on the side of the opening edge stone, and the diameter is 10cm. The net distance between the holes is determined according to the number of holes. The water inlet hole 2 half of collecting rainwater is buried under the traffic road surface 7, and half is arranged on the road surface and forms the hole of " doorway " shape. The perforated earth retaining board of each U-shaped groove block is arranged on the side of the perforated earth retaining board, and there are 1 to 4 drainage holes 4 arranged horizontally, each with a diameter of 5 cm and a clear distance between the holes of 10 cm. The net distance from each end is 5cm, and the net distance between the two prefabricated U-shaped groove bar components is also 10cm.
