Problems solved by technology

(2) Road rainwater runoff enters the water system in the form of pipeline discharge, which causes waste of rainwater to a certain extent, and cannot enable the city to obtain effective water resources after waterlogging
[0006] The above-mentioned patents have the following disadvantages: 1. The rainwater infiltration path is single, and the drainage speed cannot be effectively solved
2. There is no waterproof setting on the top surface of the subgrade, which will cause waste of water resources
3. The single type of bricks cannot meet the requirements of flexible selection of pavement paving
4. The drainage path after rainwater collection is not clear

Embodiment 1

[0037] Such as figure 1 As shown, it is a schematic diagram of the drainage brick provided in this embodiment. It can be seen that the drainage brick of this embodiment is rectangular, and the bottom surface is provided with a through drainage groove 1 on the opposite bottom edge. In order to improve drainage efficiency, the direction of the drainage groove setting To penetrate the width direction, the height of the drainage groove 1 is 1 / 3 of the height of the drainage bricks, and the drainage bricks are permeable bricks.

[0038] Use the above drainage bricks for urban road construction. The size of the drainage bricks is 220mm×115mm×60mm (length×width×thickness), and the width of the drainage groove is 30mm. The specific steps are as follows:

[0039] Step 1: Clean up the dust and sundries on the surface of the subgrade. If the part is uneven, the convex part should be chiseled flat, and the concave part should be filled up.

[0040] Step 2: Lay the cement gravel cushion,...

Embodiment 2

[0047] Such as image 3 As shown, it is a schematic diagram of another kind of drainage brick structure provided by this embodiment. It can be seen that the drainage brick shown is hexagonal, and each side of the bottom is provided with a drainage groove 1 perpendicular to the side, and each drainage groove is in the The centers at the bottom converge and connect with each other to form a connected drainage system.

[0048] Use the above drainage bricks for the construction of urban roads. The size of the drainage bricks used is 120mm×60mm (side length×thickness), and the width of the drainage groove on each side is 25mm. The specific steps are as follows:

[0049] Step 1: Clean up the dust and sundries on the surface of the subgrade. If the part is uneven, the convex part should be chiseled flat, and the concave part should be filled up.

[0050] Step 2: Lay the cement gravel cushion, remove the sundries on the cushion, fine-tune the level with coarse sand and compact it. ...

Abstract

The invention discloses a water draining brick for urban roads and a water draining method. The water draining brick is characterized in that a water draining groove is arranged at the bottom part ofthe water draining brick, and at least penetrates through a group of opposite bottom edges of the bottom surface, so that good water draining effect can be achieved, and meanwhile good supporting performance can be ensured. The water draining method comprises the following steps of: firstly carrying out construction of a cement-gravel cushion layer and a cement-mortar leveling layer on a road bed,and then splicing and paving the water draining brick according to the position of a water flow groove. The water draining brick and the water draining method disclosed by the invention have the beneficial effects that by the penetrated groove channels, rainwater permeating from the brick can flow to a water draining ditch at one side of a sidewalk, so that the purpose of fast water drainage is achieved; the rainwater collected by the water draining ditch can be reasonably utilized so as to conform to the development idea of a sponge city.

Description

technical field [0001] The invention relates to the technical field of urban roads, in particular to a drainage brick for urban roads and a drainage method. Background technique [0002] The process of urbanization in my country is accelerating. With the continuous expansion of urban construction, environmental problems such as urban water resource shortage and water pollution have emerged, which have greatly plagued urban development. The new concept of sponge city has aroused people's high attention. It has changed the traditional concept of urban management and broken through the idea of ​​urban rainwater management "based on drainage". In the process of urban road design, it is of great practical significance to realize the rational utilization of rainwater resources and maintain the urban ecological and hydrological environment. [0003] The drainage treatment measures of urban roads in my country mainly use the urban rainwater pipe system to realize the management of ...
