Lime, fly ash and gravel mixture rolling method for survival and conservation

I. Lime, fly ash, gravel mixture rolling method

The compacted thickness of lime, fly ash and gravel mix is ​​up to 20cm. Paved mixes should be rolled immediately. Before the roller compaction work, the thickness and actual elevation of the paving shall be checked again, and the rolling shall be carried out from the low point to the high point without fail. After the first rolling, the stop shall be stopped for repair. As the paving, there may be dense and loose uneven phenomenon, the initial pressure will be found two times the level of uneven phenomenon, for low places should be used to fill the aggregate mixture of more aggregate, for high places, should be scattered to dig Unequal pits, and then spread the surrounding mix with iron shovels, can not directly use the shovel to remove part of the aggregate method. After repairing, rolling can continue until the density requirement is reached. It is not possible to supplement the work of seeking compensation, and it is not possible to throw sand on it. The surface after rolling should be rough, with coarse aggregates on the surface.

田径场地

During the entire rolling process, there should be no water accumulation on the surface of the mixture to prevent sticking and squeezing. In case of sticking and grinding, the sticky and grinded mixture should be scooped off in time. At the same time, it is necessary to carefully inspect the entire site for the phenomenon of tumble, such as the presence of differently sized elastic surfaces, or the presence of transverse cracks in the direction of the vertical rolling wheel. Found a place to be dealt with in a timely manner, the treatment method is to completely excavate the mixture of all elastomers, re-filled into the new mixture.

For segmented work, the place where the joint is located may be 30-50cm long without rolling, and when the second stage is paved, the unpressed area will be reserved for planing, mixing the old and new materials. Add a bit of water to the ground, after the smoothing and smoothing, you can use the entire roller compaction. After the roller compaction is completed, check for unevenness. If there is any unevenness, you should continue to trim once.

2. How to maintain after the survival of lime, fly ash and gravel base?

The compacted lime, fly ash, and gravel bases have not finished the entire process of the knot board, so the maintenance work should be carried out in time after compaction. The main method is to sprinkle the water on the compacted surface. The watering method can be sprinkled with water or can be sprayed with tap water. No matter which method of spraying, the surface of the mixed material should be kept moist after compaction. The surface of the mix is ​​damaged by spraying the curing water.

The time for conservation should not be less than 6 days after the completion of rolling.

If asphalt mixture emulsion is sprayed on the top of the mixture, asphalt emulsion should be sprayed in time, and the surface of sprayed mixture can be cured without watering.

During the entire maintenance period, mechanical walking or slotting operations are prohibited.

Welded Wire Mesh Gabion

Welded Gabion Box (baskets), also known as welded stone cage, are made of Welded Wire Mesh panel. Welded gabion baskets can be connected with other similar containers and filled with stone to form flexible and permeable structures for retaining of riverbank and soils.This kind of wire mesh containers are uniformly welded and can be supplied of various sizes.

Characteristics
(1) Economic:just fill the stone into the Gabions and seal it
(2) Simple installation: no special technology needed
(3) Weather proof under natural destroy, corrosion resistant
(4) No collapse even under big scope of deforming
(5) Sludge in the stones is good for plant growing
(6) Good permeation can prevent the damage by hydrostatic
(7) Less transport freight. It can be folded together for transport and further installation
