revetment cedar pilesThey are wooden piles made of fir and are mainly used to treat soft foundations, river embankments, slope protections, revetments, etc. The raw material is fir, which is also called sandwood or sand tree.revetment cedar pilesThe wood is yellow-white, sometimes with light reddish-brown heartwood. It is soft, fine, fragrant, straight-grained, easy to process, has a specific gravity of 0.38, has strong corrosion resistance, and is not eaten by termites.revetment cedar pilesThe soft soil belongs to the composite foundation. The composite foundation is composed of soft soil and fir piles, so the load around the fir piles is borne by the fir piles. Suqian Water Conservancy Project fir pilesrevetment cedar pilesThe main features are: high strength and low density, with the advantages of light weight and high strength, good elasticity and toughness, can withstand impact and vibration, corrosion resistance, and good durability. The material is light and soft, easy to dry, has small shrinkage, does not warp and crack, and is durable. Good performance, easy processing, good bonding performancerevetment cedar pilesIf the defects are easy to observe from the outside, the defective fir wood piles will not be used for important structures. Some fir artificial fast-growing timbers grow quickly, have wide annual rings, become timber quickly, and have low density. For example, the density of the fast-growing fir wood is low. Less than 0.5g\/cm3.revetment cedar pilesSince hammering is used during construction, there is a strong squeezing effect around the pile body, which increases the density of the soil layer within a certain range of the pile, thereby increasing the bearing capacity of the soil between the piles and reducing the compressibility.revetment cedar pilesIssues that need attention when using: Do not replace "fir wood piles" with "pine wood piles" or other piles. Many woods will corrode if soaked in water for a long time. They will soon turn black, deformed and rotten in the water, especially in the humid south. , the water level changes greatly and rots quickly, so it must not be used.revetment cedar pilesWhen driving piles in the soil, gravel or pebble layer, pile boots need to be installed on the ends of the wooden piles to prevent the fir piles from being driven in rows.revetment cedar pilesThe materials used should be based on the design size, with few knots, corrosion-free hollows, small head diameter differences, the bending vector of the entire length of the pile wood should not be greater than half of the pile diameter, and the twist of the wood grain within 1 meter of the installed wood should not be Larger than half the circumference of the pile log
revetment cedar pilesBoiled in bitumen to preserve it.

revetment cedar pilesThe design method of composite foundation is similar to that of ordinary composite foundation, but the pile spacing of fir piles is very small.

revetment cedar pilesIt is generally used in the construction of some river slope protection projects and as support poles for greening trees. Generally speaking, fir piles have a small diameter, so handling, transportation and installation are more convenient, and their strength is not Because of the impact of being too thin, fir has relatively good toughness and strength, making it a very good choice for greening support poles.

revetment cedar pilesIts cost performance is very high, which is mainly due to the rapid growth rate of fir. In fact, the growth rate of fir is quite fast, and it is widely planted in the Huaihe River Basin, so the output is quite huge, so the price is relatively It's lower.

revetment cedar pilesIts anti-corrosion and insect-proof effect is very good. In many cases, it can be used underwater and in other harsh environments for a long time. At the same time, the smell of fir is also very effective in preventing insect damage, and it is used in construction. , furniture manufacturing and other aspects are very good.
