Problems solved by technology

[0002] Hard soil roads tend to be muddy in rainy days. Although the road surface will remain hard after drying, the mud in rainy days will change the shape of the road surface. Over time, the hard soil road surface will become potholes, which is very unsuitable for vehicles.
The existing hard soil road repair method is to use a large amount of cement and stones as raw materials for road repair, which requires a large transportation cost and also pollutes the environment. Therefore, we propose a hard soil special curing agent and its application method to solve the above problems

Embodiment 1

[0037] A special curing agent for hard soil is calculated in parts by weight. The raw materials of the curing agent include: 40 parts of polyacrylamide, 10 parts of nonionic surfactant, 160 parts of polypropylene glycol, and 70 parts of glass fiber.

[0038] The preparation method of above-mentioned curing agent comprises the following steps:

[0039] The first step, polyacrylamide, nonionic surfactant, polypropylene glycol, glass fiber are poured in the mixing tank of sealing, form mixture;

[0040] The second step is to raise the temperature of the mixed solution in the mixing tank to 100-110°C, and continue to stir the mixed solution at this temperature for at least 1 hour until the properties of any part of the mixed solution are consistent with other components of the mixed solution. the parts are of the same nature;

[0041] The third step is to fill and seal the mixed solution in the mixing tank to form a curing agent.

Embodiment 2

[0043] A method for applying a special curing agent for hard soil, comprising the following steps:

[0044] The first step, soil layer preparation: excavate and collect hard soil at a depth of 20 cm on the surface of the hard soil road surface, and level and compact the excavated hard soil road surface;

[0045] The second step, soil layer crushing: put the hard soil excavated in the previous step into a grinder to crush;

[0046] The third step, material mixing: Pour the crushed hard soil into the hard soil special curing agent diluted with water, and use a mixer to fully stir to form pavement materials;

[0047] The fourth step, pavement laying: spread the pavement material obtained in the previous step into the hard soil pavement, use a road roller to press it once, and then use a grader to shape it;

[0048] The fifth step, pavement forming: Repeat rolling with a vibratory roller for no less than 4 times;

[0049] Step 6. Road surface maintenance: After rolling and formi...

experiment Embodiment 1

[0051] The hard soil road surface that uses curing agent of the present invention to build carries out rainwater test:

[0052]1, adopt the scheme of embodiment one to prepare the special curing agent for hard soil, use the scheme of embodiment two to build a hard soil road surface as No. 1 road surface;

[0053] 2. Select an untreated hard soil road surface as the No. 2 road surface, and the experimental areas of the No. 1 road surface and the No. 2 road surface are the same;

[0054] 3. Use the shower to evenly spray the same amount of water on the two roads to simulate the rainstorm situation;

[0055] 4. After the water spraying is over, a homogeneous steel ball with a diameter of 10 cm is dropped freely from the height of 1 meter on the two roads at the same time, and a total of 10 target points are selected, and the experiment is repeated until all 10 target points are tested Finish;

[0056] 5. After the two road surfaces are completely dry, measure the relative heigh...

Abstract

The invention discloses a special hardener for hard soil and an application method of such hardener. The special hardener for hard soil comprises, by weight, 160-180 parts of polyacrylamide, 10-15 parts of nonionic surfactant, 150-160 parts of polypropylene glycol and 60-70 parts of glass fibers. Existing hard soil pavements for building low-grade roads are mostly built by cement and gravels, so that the original rural ecological environment is damaged and a great quantity of transport cost is wasted. The special hardener for hard soil has the advantages that local materials are utilized sufficiently to enhance the strength of the hard soil pavements, so that the hard soil pavements can bear higher transport volume; the hard soil pavements in rainy days cannot be muddy and deform due to softening, so that daily travel and transport are facilitated; the hardener is suitable for constructing the rural low-grade roads.

Description

technical field [0001] The invention relates to the related technical field of soil solidification, in particular to a special solidifying agent for hard soil and an application method thereof. Background technique [0002] Hard soil roads are prone to mud in rainy days. Although the road surface will remain hard after drying, the muddy rain will change the shape of the road surface. Over time, the hard soil road surface will become potholes, which is very unsuitable for vehicles. The existing hard soil road repair method is to use a large amount of cement and stones as raw materials for road repair, which requires a large transportation cost and also pollutes the environment. Therefore, we propose a hard soil special curing agent and its application method to solve the above problems. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a special curing agent for hard soil and its application ...
