preparation example Construction

[0049] A preparation method of environmentally friendly road paving blocks includes the following steps:

[0050] S1 prefabricated slurry, spare;

[0051] S2 Insert a hollow permeable pipe into the mold; weave the recycled steel bars to form a reinforcement layer for use;

[0052] S3 Pour half of the prefabricated slurry into the mold with the hollow permeable pipe inserted. After the prefabricated slurry is solidified, place the reinforcement layer woven in S1 on the solidified prefabricated slurry; then pour the remaining prefabricated slurry The material solidifies to form the top prefabricated layer.

[0053] Insert the permeable pipe in advance, on the one hand, it is not easy to block the cavity of the permeable pipe, on the other hand, the permeable pipe and the prefabricated slurry are better bonded. First import half of the prefabricated slurry, and place the reinforcement layer after solidification. It has better support for the reinforcement layer and easier to control the...

[0066] Preparation method of environment-friendly road paving block

[0067] In order to further improve the comprehensive index of the paving block and improve the construction efficiency, the inventor further improved the preparation method of the environmental protection road paving block. The difference between the preparation method of Example 10 and the above environmental protection road paving block is: The steel bar is inserted into the permeable pipe in the finished product obtained in S3, and the finished product is heated at a temperature of 850-880°C for firing for more than 72 hours.

[0068] In order to save test costs, the inventors only made the above improvements to the paving blocks prepared in Examples 3, 6, and 9. Although the water permeability was slightly reduced, it still reached T2 classification (≧150ml / min), compressive strength and resistance The folding strength is greatly improved, both increased by 12%-15%.

[0070] Construction waste treatment method

[0071] The comprehensive index of the paving block, the efficiency of the entire construction also includes the early garbage treatment. The inventor also improved the construction waste treatment method. The specific steps are as follows:

[0072] Step 1. Screening, screening the construction waste to obtain initial aggregates, stones, steel bars, plastics and other waste;

[0073] Step 2. Crush the rocks, put the rocks in a cooling chamber below 0°C for cooling, cool for more than 10 minutes and then crush them, and then screen them to obtain cooled aggregates after crushing;

[0074] Step 3. The initial aggregate obtained by the screening and the cooled aggregate are mixed and used in the environmental protection road paving blocks of Examples 3, 6, and 9.

[0075] After the above treatment, the stones are more easily broken, which is beneficial to improve the construction efficiency.

[0076] Furthermore, in step 2, spray water to lower th...

Abstract

The invention relates to the technical field of construction waste utilization and in particular to an environment-friendly road and a method for preparing environment-friendly road paving blocks. Theenvironment-friendly road comprises a water-permeable layer disposed on a foundation and a sand layer disposed on the water-permeable layer, wherein the water-permeable layer is formed by splicing paving blocks; the adjacent paving blocks are bonded by an adhesive; each paving block comprises a bottom pouring layer, a middle reinforcing layer formed by weaving steel bars and a top pouring layer;hollow water-permeable tubes pass through the paving blocks; and each paving block contains over 40% by weight of construction waste. The paving blocks are mainly used for paving roads in parks or forests, can use more construction waste under the premise of ensuring a required strength, is environmentally friendly, and has a good water-permeable effect.

Description

Technical field [0001] The invention relates to the technical field of recycling and utilization of construction waste, in particular to a preparation method of environmental protection roads and environmental protection road paving blocks. Background technique [0002] With the continuous development of society, urban municipal construction is also showing a trend of rapid development. Along with the demolition of many buildings, the construction waste generated during the demolition process needs to be screened first, and then recycled, reused or treated separately after screening. . [0003] Reuse of construction waste can not only reduce the environmental problems caused by waste dumping, but also save resources. Therefore, the effective treatment of construction waste is particularly important. The composition of construction waste is complex, and most construction waste contains a large amount of waste concrete. Research at home and abroad believes that it is feasible to use...
