Problems solved by technology

[0003] However, the construction of permeable pavement is different from ordinary roads. In order to maintain the water permeability of the pavement, the bonding layer of permeable bricks cannot use ordinary concrete, otherwise it will block the infiltration of rainwater; the existing permeable bricks are mainly paved on sand cushions When laying bricks, use a rubber hammer to lightly knock them flat, but the stability of the sand cushion is not high, which may easily cause problems such as settlement and fracture of permeable bricks

Embodiment 1

[0025] Such as figure 1 As shown, a waste steel slag permeable base layer includes a base layer 1, a curb 2, a crushed stone stabilization layer 3, a permeable concrete layer 4, a leveling layer 5, and a permeable brick 6. The base layer 1 is a cleaned road. Curb stones 2 are arranged on both sides of the base layer 1, the gravel stabilizing layer 3 is evenly laid between the curb stones 2 on the base layer 1, and the permeable concrete layer 4 is laid on the gravel stabilizing layer. On layer 3, the permeable concrete layer 4 is a permeable concrete structure with pores inside, the leveling layer 5 is laid on the permeable concrete layer 4, and the material of the leveling layer 5 includes waste steel slag and cement, The permeable brick 6 is laid on the leveling layer 5, the permeable bricks 6 are connected by a fine sand layer 7, and the fine sand layer 7 connects the permeable brick 6 and the curb stone 2. The permeable brick 6 includes a bottom water permeable layer 8 and...

Embodiment 2

[0038] Such as figure 1 As shown, a water-permeable base layer of scrap steel slag has a structure as described in Example 1.

[0039] A method for laying a permeable base layer of waste steel slag includes the following steps:

[0040] Step 1. Preparation before laying: clean the surface of the base layer 1 where the permeable base layer is to be laid, and set curbs 2 on both sides of the base layer 1;

[0041] Step 2. Laying the crushed stone stabilizing layer 3: The crushed stone stabilizing layer 3 is made of crushed stones with a particle size of 5-20 mm, and they are evenly laid on the surface of the base layer 1 cleaned in the step 1, and the surface is poured after laying. Water to wet the surface of the crushed stone stabilizing layer 3, and the thickness of the crushed stone stabilizing layer 3 is preferably 35 cm;

[0042] Step 3. Laying the permeable concrete layer 4: The permeable concrete layer 4 is a concrete structure with pores and permeable inside, and is evenly lai...

Abstract

The invention discloses a waste steel slag permeable base layer and a laying method thereof. According to one aspect of the invention, a waste steel slag permeable base layer is provided, and comprises a base layer, kerb stone, a crushed stone stabilizing layer, a permeable concrete layer, a leveling layer, and a permeable brick, wherein the leveling layer is laid on the permeable concrete layer,and the materials of the leveling layer include waste steel slag and cement. According to another aspect of the invention, a laying mode of the waste steel slag permeable base layer is provided, and includes six steps. The materials of the leveling layer adopts the waste steel slag produced by directly placing the residue after iron ore smelting in cold water, not only the waste steel slag is treated, but also the inside of the waste steel slag has a honeycomb structure, which improves the permeability and saves energy, compared with a sand cushion, the stability of the leveling layer is greatly improved, and the structural stability of permeable bricks is ensured.

Description

Technical field [0001] The invention relates to the field of paving methods for base layers, in particular to a water-permeable base layer of waste steel slag and a paving method thereof. Background technique [0002] As a new type of environmentally friendly and ecological roads, permeable roads have received increasing attention from people, especially the industry. Permeable roads can quickly seep rainwater into the ground, effectively replenish groundwater, alleviate the urban heat island effect, and balance the urban ecosystem. Permeable ground can also permeate "earth air", making the ground warm in winter and cool in summer, permeable in rainy season, and melting snow in winter, which can increase the comfort of urban living. In addition, because the permeable ground has many pores and large surface area, it has a strong adsorption force for dust, which can reduce dust pollution and noise. Permeable brick is a very important environmental protection material for paving p...
