sheet piles currently used more widely in the country, by the praise of many construction projects. Common to stop, harbor, shipbuilding, construction and other projects in the river. We then construction how to calculate the correct distance between sheet piles and the support layers this is very important. Next Shun force steel industry has to share with you calculated data sheet pile support and the support layer distance:
sheet piles supporting data calculation
A sheet piles retaining data calculated
A height H1: 4.100 Mi construction water level H2: 3.000 m 2 ground elevation H0: 4.350 m excavation bottom H3: -3.400m excavation depth H: Soil bulk density plus whole γ1 average of 7.7500 m3: 18.3 KN / m soil rotameter bulk density γ ': 10.0KN internal friction angle plus whole averaged Ф / cubic meter: 20.10 ° 4 uniforms Q: 5 excavation length 20.0KN / 2 = 0.0 square Mickey excavation width b = 9.0 Meter
(1) in the external representation of the sheet piles
sheet pile Ka pressure distribution, strength and earth pressure = TG2 (45 ° -φ / 2) = TG2 (45-20.10 / 2) = 0.49 KP = TG2 (45 ° + φ / 2) = TG2 (45 + 20.10 / 2) = 2.05
In terms of foreign filling height of sheet pile uniform load H, H = Q / R = 20.0 / 18.3 = 1.09 m earth pressure on top of a pile of PA1 PA1 = R × (H + 0.25) = Ka × 18.3 (1.09 + 0.25) × 0.49 = 12.0KN / m²
Soil moisture compressive strength PA2 to PA2 = R × (H + 4.35 -3.00) = Ka excavation face earth pressure 18.3 × (1.09 + 4.35 -3.00) × PA3 PA3 0.49 = 21.8KN / m² = R × (H + 4.35 - 3.00) + (R-RW) (3.00 + 3.40)} = Ka × 18.3 (1.09 + 4.35 -3.00) + (18.3-10) × (3.00 + 3.40) × 0.49 = surface water pressure excavation 47.8KN / square m (after cofferdam pumping) PA4: PA4 = γ (3.00 + 3.40) = 10 × (3.00 + 3.40) = 64.0KN / m²
Second, the number of layers of sheet piles supporting distance interval
Bend and other arrangements in accordance with arrangements to see the sheet pile from the maximum bending can withstand the maximum allowable range of the pile board on top of the cantilever end is how much? According to our specific formula to obtain accurate data σ = M / WZ sheet piles. The maximum bending moment M0 = WZ × [σ] = 189.0KN * m
Technological innovation is the power of genes along the rapid development of China's first cold-formed sheet piles patent was born in Hue force along the force to build R & D team to lead the development direction of the global sheet piles, it won more than 20 national invention patents, utility models patent.
After two decades of development, the formation of more than two thousand full range of product specifications:
U-shaped cold-formed sheet piles, Z-type cold-formed steel sheet piling, wide hat cold-formed sheet piles, corrugated sheet piles retaining, H-shaped sheet piless, steel pipe piles, hot-rolled and cold-formed locking connector, etc., in the face various engineering and customers can provide the best cost-effective SL series.
