How to write the content of laying water stability, and how to write a brief description of the wate

Kiss! Hello, happy to answer your <>

The pro-construction process is as follows: 1. Preparation of virtual work, which includes quality inspection of raw materials, material preparation, confirmation of construction mix ratio, site cleaning, equipment status confirmation, etc.; 2. Measurement control, the process includes surveyors according to the requirements of the specification and equipment parameters to make points and lofts, generally marked with steel nails and red cloth; 3. Transportation, the process includes centralized mixing of mixed materials, and transportation of qualified vehicles to the site for paving after unified management; 4. Paving and shaping, the process includes the equipment entering the predetermined point, paving at a uniform speed, continuous and uninterrupted, rolling the roller to the surface without traces, process inspection and trimming; 5. Joint treatment, which mainly refers to the cleaning of the increased transverse joints due to construction interruption; 6. Health preservation, the process includes the setting of signs, sprinkling water to nourish the tung tree, etc. Points to note in the construction of water-stabilized layer 1, in the design of the mix ratio, in the case of meeting the strength requirements, choose a smaller amount of cement.

The blind pursuit of high-dose cement can ensure strength, but it is not economical and prone to vertical and horizontal cracks. The actual amount of base cement should be controlled in the range of 3-5%, which not only ensures the quality of construction, but also is very economical. 2. Set the elevation indicator pile when paving, and the wire is made of 2-3mm stainless steel wire.

When tensioning, it is fixed with a tensioner, and the tensioning force is not less than 800N, and the length of each erection is not greater than when the top surface of the water-stabilized layer is constructed on the inner side of the super-high section, if the longitudinal drainage ditch of the super-high section has been completed, the height of the water-stabilized layer near the ditch should be strictly controlled. In general, the elevation of the top surface after compaction should be controlled at 2cm to ensure the thickness of the screed in the middle area. Hope mine can help you <>

Do you have any other questions?

<> water first blind stabilized gravel is used in the paving water stabilized layer. The water-stabilized layer is the abbreviation of the cement-stabilized gravel layer, that is, the cement is used to consolidate the graded gravel, which is completed by compaction and curing. The water-stabilized mix with celery ratio should be tested in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregates, and at the same time Tan Wang to determine the maximum dry density, and the water stabilized mixing plant can be used to mix the large amount.

Its initial strength is high, and the strength increases with the age and quickly forms a plate, so it has high strength, impermeability and frost resistance. The dosage of water-stabilized cement is generally 3%-6% of the mixture, and the unconfined compressive strength can be reached in 7 days, which is higher than that of other subgrade materials. After the water is stable and survives, it is not muddy in the rain, and the surface is solid, which is an ideal base material for high-grade pavement.

Hydrostabilisation is the abbreviation of water-stabilized layer, and the full name is cement stone powder stabilized layer.

The general practice of the construction site of the water-stabilized layer is as follows: a car of stone powder (about 20 cubic meters) plus 16 20 bags of cement.

Machinery (mostly hook machine) mixing, watering, flattening, compacting.

Of course, there is a design or a design.

It is the construction of cement stabilized layer, which is divided into cement stabilized gravel, cement stabilized gravel, etc. according to different materials.
