However, there are fewer and fewer places around the city that are suitable for use as receiving sites. As a last resort, the existing receiving sites can only be overloaded to form artificial mountains. The soil quality of this artificial mountain is relatively loose. Affected by changes in the geographical environment and

Embodiment 1
[0046] Example 1: 80% of soil, 20% of soil modifier, mixed evenly, and further mixed in an internal mixer at a temperature of 130-150 degrees Celsius to form;
Embodiment 2
[0047] Example 2: 85% of soil, 15% of soil modifier, mixed evenly, and then further mixed in an internal mixer at a temperature of 130-150 degrees Celsius to form;
[0048] Implementation: 3: The soil is 90%, and the soil modifier is 10%, mixed evenly, and then further mixed in an internal mixer under the condition of 130-150 degrees Celsius, and it can be formed;
[0049] As for the soil modifier, it can be mixed with 5-8 parts of cellulose, 1-3 parts of urea and 6-10 parts of ethylene-vinyl acetate copolymer;
[0050] For example, it can be made by mixing 5 parts of cellulose, 1 part of urea and 6 parts of ethylene-vinyl acetate copolymer; it can also be mixed with 7 parts of cellulose, 2 parts of urea and 8 parts of ethylene-vinyl acetate copolymer It can also be mixed with 8 parts of cellulose, 3 parts of urea and 10 parts of ethylene-vinyl acetate copolymer.
[0051] The cellulose in the present invention can be hydroxyethyl cellulose, hydroxypropyl methyl cellulose or h...
Embodiment 3
[0083] The abrasive member 111 can be made of the following high carbon iron alloy, which is composed of 16% by weight of titanium, 6% of carbon, 3% of silicon, 3% of lead, 8% of tungsten carbide, 0.3% of copper, 5% of boron, and 5% of chromium. , the remainder is iron.
[0084] The difference between the above alloys is that copper is generally considered a harmful element for iron alloys and cannot be used, but the present invention greatly improves the iron-titanium alloy by adding copper element and tungsten carbide into the iron-titanium alloy. Wear resistance.
[0085] Abrasive parts of the present invention and the comparison test method and results of the wear resistance of iron and titanium alloys purchased on the market:
[0086] Test method, using device, ML-10 abrasive wear testing machine, 200# corundum sandpaper, balance of 1 / 10,000 precision. The sample speed was 180 rpm, the normal load force was 750 N, and the time was 4 hours.
[0087] test results:

Abstract
The invention discloses a system for industrially treating silt residue soil. The system is mainly applicable to treating mud and sandy soil dug during urban construction and comprises an integral drum type mud and sand separating device, a mud and sand separating device and a mud treating portion. To-be-treated mud and to-be-treated sand can be primarily treated by the integral drum type mud and sand separating device; coarse sand and fine sand in the mud can be separated from each other by the mud and sand separating device; the mud without the sand further can be finely treated and then can be dehydrated by the mud treating portion to obtain dry mud for standby application. The system has the advantages that the to-be-treated mud and the to-be-treated sand are treated by the drum type mud and sand separating device to obtain dilute mud, sand and bulk material mixtures, and accordingly the waste soil transported by soil vehicles can be directly poured into the separating devices and can be quickly treated to obtain the dilute mud, sand and bulk material mixtures without being stacked; pottery products or porcelain products can be made of treated soil according to difference of soil components, accordingly, all waste can be truly completely utilized, waste materials can be recycled, and the system is a green and sustainable project.
Description
technical field [0001] The present invention relates to a processing system for processing silt and slag produced in the process of urban construction, in particular to the slag produced in the soil dug out in urban construction, such as subway construction, building foundation excavation and the like. technical background [0002] Subway construction and high-rise building construction are signs of a city's rapid development. In subway construction and high-rise building construction, a large amount of excavated soil is bound to be produced. At present, there is only one way to deal with this kind of soil, that is, to set up a number of soil receiving fields in the surrounding areas of the city, where it is suitable for piling soil. The soil generated in the process of urban construction is directly sent to these receiving sites for landfill through dirt trucks. This treatment method is essentially to transfer the soil excavated from the places that need to be built to the...
