About crash bearer horizontal layout:
First build water intake and outlet, arine railway, pump house river arrange landing stage etc., all must not take planning navigation channel.Crash bearer is arranged at water-fetching head front end 1.20m, both sides 4.01m, distance embankment about 34.31m；Distance downstream wide pearl railway bridge about 36.85m；Water river road, distance south boat trough rim line about 9.82m, the horizontal layout of crash bearer is rational.Leg, the engineering place depth of water is about 2～3m, and anti-collision facility cope level etc., higher than highest navigable stage, is Huanghai Sea elevation 2.646m.
About engineering department designed navigable stage:
Navigation channel, engineering place is connected into Huang Maohai by downstream sluice mutually with precipice door channel, and upstream drips, by Nan Shuiyunhe, Nan Shui, a water channel of crowing with chicken in Nan Shui river mouth and is connected, and intake position and chicken crow a water channel at a distance of about 15km.Precipice door channel lowest navigable stage is Huanghai Sea elevation-1.438m, and a chicken water channel lowest navigable stage of crowing is Huanghai Sea elevation-0.734m, and engineering downstream sluice lowest navigable stage is Huanghai Sea elevation 0.39m.Owing to section, engineering place is by water gate control, belong to comprehensive utilization region, should be according to the requirement of comprehensive utilization and combine the regulation of this standard the 6.2.2 article and determine according to the 6.3.2.2 lowest design navigable water level in " inland navigation standard ", therefore it is the lowest navigable stage of engineering department that suggestion takes the crow Huanghai Sea elevation-0.734m of a water channel lowest navigable stage of chicken.Taking the crow Huanghai Sea elevation 2.646m of a water channel highest navigable stage of chicken is the highest navigable stage of engineering department.It is rational that design navigation low water level takes Huanghai Sea elevation-1.42m.
About crash bearer layout design:
Crash bearer is designed by VIII grade of crashproof ability in navigation channel, and ship navigation tonnage is 30 tonnes.
In order to avoid the collision to newly-built intake 6, each at water intake 6 front end 1.20m, both sides 4.01m a crash bearer 7 is set, each crash bearer 7 is made up of navigation light 5 high for 1.5m on 6 Φ 325 steel-pipe piles, cushion cap 1 thick for stake top 0.8m and cushion cap 1, and pile foundation end points is not past cushion cap frontal line.Anti-collision facility cope level is higher than highest navigable stage, is Huanghai Sea elevation 2.646m.Stake top mark a height of Huanghai Sea elevation 1.946m, absolute altitude at the bottom of stake is Huanghai Sea elevation-41.65m.Steel-pipe pile is straight stake, vertical bearing capacity of single pile eigenvalue Ra=500kN.Steel-pipe pile and reinforcement steel plate material use Q345B steel (16Mn).
The long 3.6m of cushion cap 1 of described each crash bearer, wide 2.2m, thick 0.8m, produce crash bearer during for preventing ship collision and destroy, and each crash bearer front end respectively sets a D200*200*2000 rubber fender；During for preventing ship collision producing hull and destroy, both sides, cushion cap 1 front end set top rake 350*600.
Specific embodiment 2:
Being technically characterized by comprising the steps as follows: of this specific embodiment 2 arranges at least two crash bearers 7 in the front end of intake 6 and both sides; described crash bearer 7 is distributed in before intake 6 and both sides; intake 6 is formed cambered surface protection structure; it is distributed in before intake 6 and the crash bearer 7 of both sides, forms the semi-surrounding structure to intake 6；Crash bearer 7 front is 1-1.3 rice with the front air line distance of intake 6, forms the front safeguard protection distance to intake；Being positioned at the crash bearer 7 of intake 6 both sides, inside it, the air line distance with intake 6 side is 3.5-4.5 rice, forms the side airbag guard space to intake；I.e. formed prevent boats and ships from front, the crash bearer structure of side impact intake 6.Remaining is with specific embodiment 1.
