Problems solved by technology

[0003] Patent No. 200410008727.0 discloses "a soil curing agent for road construction", that is, the main components are dry fly ash and desulfurized gypsum produced when burning sub-coal or lignite in a power plant, and quicklime and / or cement, cooked It is made of gypsum, aluminum sulfate or alunite by forced mixing. This method is complicated to construct, and the structure is unstable, easy to damage, and the service life is not long, so it needs to be improved.

Embodiment Construction

[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] In July 2010, the inventor made a bio-enzyme-modified roller compacted concrete road test project construction on his own kiwi fruit park road in Lianghekou Village, Cenxi Township, Xiushan County, Chongqing City, and the construction road surface was 2100m long. The construction steps are as follows:

[0022] First prepare the materials, prepare biological modifiers, flexible fibers, coarse aggregates, sand, cement and biological enzymes, and the mixture ratio is: biological modifiers: flexible fibers: coarse aggregates: sand: cement = 2: 1:1650:495:250. Dry mixing is carried out first, that is, the above-mentioned proportioning materials are forced to mix, and then the biological enzyme is sprayed, that is, the biological enzyme solution is evenly sprayed on the dry-mixed material. The ratio of biological enzyme to the mixed mater...

Abstract

The invention discloses a bio-enzyme modified roller compacted concrete road engineering construction technology in which bio-enzyme is used as a curing agent and which is low in construction cost, and is easy to implement, pollution-free, low-carbon and environment-friendly. The technology has the advantages that a road base has high intensity and water stability and a good effect of stabilizing and curing soil. Compared with the conventional road building material, a bio-enzyme road is high in load carrying property, good in road performance, and high in construction speed, and low in cost, and easy to construct; and compared with the conventional road building technology, a bio-enzyme road engineering construction technology can save fund by 10 to 20 percent, and has obvious economic benefit and social benefit; the road is easy to cure, and the bio-enzyme road engineering construction technology greatly reduces the using amount of lime and cement, so the resources are saved; the used materials are mostly waste slag, spoil, hole slag, building slag and other waste materials, damage to an ecological environment is reduced, and the bio-enzyme modified roller compacted concrete road engineering construction technology has obvious economic benefit and social benefit.

Description

technical field [0001] The invention relates to a road construction technology, in particular to a biological enzyme modified roller compacted concrete road engineering construction technology. Background technique [0002] At present, my country's highway construction is advancing by leaps and bounds, and the investment is huge. Semi-rigid bases with lime, fly ash, cement and gravel as the main materials are mostly used as pavement bases. With the development of highway construction, the amount of construction materials such as sand and stones is also increasing, making these natural resources increasingly The destruction of the natural environment by its exploitation is becoming more and more serious. Therefore, it is of great practical significance to continuously develop and utilize some new building materials and build environment-friendly and resource-saving highways. [0003] Patent No. 200410008727.0 discloses "a soil curing agent for road construction", that is, t...
