Input cost is low, and construction tool is simple, operates simple and easyly, and instant effect, has replaced in the past digging machine on ship to pressPlay the loaded down with trivial details construction that steel pipe is set up steelframe platform, accelerated the progress of setting up of steelframe platform, shortened the duration,The input of having saved labour and plant equipment, has reduced Construction Cost, has reduced potential safety hazard, avoidsAt sea, the generation of interior korneforos ship construction safety accident. This construction is applicable to water conservancy dyke, edgeThe cast-in-situ bored piles waterborne such as sea is enclosed and cultivated, lock station, inland river are the geology bar such as mud, silt clay folder flour sand layerPart.
Detailed description of the invention
Bias of the present invention is vibrated and is set up steelframe platform construction engineering method, utilizes the eccentric vibrating principle of eccentric vibrator,The rotating shaft with eccentric mass that utilizes vibrator center to install, the centrifugal force producing in the time of High Rotation Speed passes throughBearing passes to oscillating flat plate, thereby makes vibrating head produce circular vibration. Eccentric vibrator is one to be hadThe motor of effect of vibration, has installed oscillating flat plate in the bottom surface of this machine, and when work, oscillating flat plate is attached to steelGuan Shang, the vibration wave that vibrator produces passes to steel pipe by Bottom Board Steel cylinder, thereby steel pipe is sunk.
This construction need to be prepared following material:
1, Φ 114 steel pipes, No. 14 channel-section steels, No. 14 I-steel, No. 5.0 channel-section steels, oxygen, acetylene, cableLine, springboard, a small amount of Φ 14 round steel, Φ 20 screw-thread steels.
2, various Escape and Survival Equipments, because this engineering method is mainly coastal sea, the riverine area of enclosing and cultivating, anti-Flood control task is heavier, and life vest, lifebuoy etc. must be equipped with.
3, plant:
3.1, intermediate frequency formula (83-133HZ, 5000-8000 time/min) is if eccentric vibrator, manual 3T cucurbitDry cover, for the insertion construction of steel pipe post.
3.2,4 covers of single flow electric welding machine, for the processing and fabricating of steel pipe post and connect in length and breadth rod member and cutCutter support welding, 2 of the two rubber-tired carts of repacking, for the transport of steel pipe post.
3.3, the some T of steel pipe, for the maintenance of steelframe steelframe platform.
This construction comprises the steps:
(a) steelframe Platform Structure Design: steel platform framed bent belongs to provisional operation platform, only executes as pile foundationWork, vertically mainly bears the loads such as a machine, steel reinforcement cage and personnel, and level is mainly born the impact of wind, wave,Therefore operation platform structure is only made Analysis of Vertical Load Capacity, does not consider the effect of horizontal force stormy waves.
1, platform structure bearing capacity and stability Calculation
Invar platform is bearing the gravity load of top stake machine and the dynamic load of ram machine construction, therefore need to be to steelPlatform inserts soil layer bearing capacity and checks, in order to prevent the stressed rear unstability of platform main member, therefore need to be rightThe main rod member of platform checks, and presses respectively XY-3 convolution drilling machine construction, and embedded rock pile adopts CZ20 to impactTwo kinds of situations of drilling machine construction are analyzed:
1.1, equipment weight parameter
1. rig circles round: convolution rig stake machine chassis is of a size of 4500 × 2000mm (L × W), and the deadweight of stake machine is45KN, irrigates by lifting water to a higher level with a water pump, etc. the frictional resistance of generation while comprising drilling rod and drill bit or conduit and perfusion concrete, and steel reinforcement cage is conducted oneself with dignity approximately10.6KN (pressing temporarily friction pile 40m steel reinforcement cage weight considers), while considering drill hole of drilling machine, to operation platform, vibrations are doneWith, getting dynamic magnification factor is 1.2.
Every ram machine construction effect total load head of convolution rig calculates: F=(45+10.6) × 1.2=66.72KN
2. percussive drill: stake machine deadweight 40KN (comprising block stamp), block stamp is to uplift force 15KN, and steel reinforcement cage is certainlyWhen heavily about 11.1KN (press embedded rock pile steel reinforcement cage weight consider) considers drill hole of drilling machine to operation platform shock effect,Getting dynamic magnification factor is 1.2.
Every ram machine construction effect total load head of convolution rig calculates: F=(40+15+11.1) × 1.2=79.32KN
According to above analysis, percussive drill construction loads is greater than convolution rig construction loads, bearing capacity, stableProperty analysis is all calculated by percussive drill construction loads.
2, Bearing Capacity of Steel Pipe Piles calculates
Because of rig work quality, be to pass to traveling roller by chassis, then pass to I-steel by traveling roller,Then pass to steel pipe post by I-steel, finally pass to ground by column. Arrange according to general maximum spacing,Calculate by worst operating mode, longitudinally maximum spacing is temporarily by 2.5 meters, and laterally maximum spacing is temporarily by 2.5Rice, every bench drill machine has the traveling roller of four, and the every long 5.0m of cylinder directly passes to afterwards therefore girder steel is stressedSteel pipe post, is mainly subject to vertical steel pipe radical N=2 × 3=6 root in a bench drill machine.
According to pile foundation technology code (JGJ94-2008) vertical bearing capacity calculation requirement, safety coefficient KGet 2, therefore single steel pipe bearing capacity is 79.32 × 2/6=26.44KN
The single stake of steel pipe post is about 10-12m, inserts the about 4-6 rice of beach face meter, and it is mud that column is squeezed into stratumLayer, silt clay folder flour sand layer, steel pipe single upright column vertical limit standard value of bearing capacity, according to pile foundation skillArt code (JGJ94-2008) steel-pipe pile calculates, the limit collateral resistance q of mudsikPress 18kpa value, become silted upThe limit collateral resistance q of shale clay folder flour sand layersikPress 25kpa value, calculate by least favorable insertion beach face 4mThe checking computations of limit by row bearing capacity, specific as follows:
Quk=Qsk+Qpk=u∑qsikli+qpkAp
Quk=3.14×0.114×(18×3+25×1)+0=28.27KN
Quk=28.27KN > F/n=26.44KN (bearing capacity meets the demands)
In formula:
U-steel-pipe pile outer perimeter
qsik-sidewall limit frictional resistance standard value λs=0.8
li-stake end enters soil depth
λp-pile end block effect coefficient, for closed steel pile tube λ=1.0
qpk-stake end limit penetration resistance standard value, for steel-pipe pile qpk≈0
Ap-stake end area
3, steel platform structure calculates
3.1, No. 14 I-steel of longeron calculate
Calculate temporarily according to 2.5 meters of maximum spacings, because stake machine entirety chassis is of a size of 4.5 × 2.0m (L × W),Chassis effect girder steel has two kinds of the most unfavorable processing condition forms substantially, and I-steel is connected all employings with channel-section steel and steel pipeBe welded to connect, I-steel calculates according to single span built-in beam.
Suppose that chassis stepless action is at each girder steel, the gravity laod of girder steel is:
F1=F/n=79.32/(3×1.5)=17.62KN
(1) No. 14 I-steel mechanics parameter
Cross sectional moment of inertia: I=712 × 104mm4, cross section resistance moment: W=102 × 103mm3,E=2.1×105N/mm2(2) the first load action operating mode
(2.1) intensity:
Mmax=2F1a2b2/L3=2×17.62×0.52×22/2.53=2.26KN·m
σ=M/W=2.26×106/102×103=22.16N/mm2<f=210N/mm2
Intensity meets the demands.
(2.2) rigidity:
Rigidity meets the demands.
(3) the second load action operating mode
(3.1) intensity:
Mmax=F1L/8=17.62×2.5/8=5.51KN·m
σ=M/W=4.63×106/102×103=54.01N/mm2<f=210N/mm2
Intensity meets the demands.
(3.2) rigidity:
Rigidity meets the demands.
Act on No. 14 I-steel through checking computations stake machine, its intensity, rigidity all meet the demands.
3.2, steel pipe post calculates
Calculate according to critical load.
In formula: K1-safety coefficient, gets K1≥1.8
μ-drift correction factor, gets 0.65
