Main construction method 1.0 Preparations1.1 Equipment: Mobilization and commissioning of tower crane, sliding d

6、evices, welder, etc, so as to ensure the slip form works in the normal way. 1.2 Materials: Work out the plan of steel and carry out the fabrication work, prepare the plan of concrete and other materials.1.3 Job site: Smooth and straight so as to ensure the convenience of material transportation.1.4

7、Adequate manpowers.2.0 Silo wall slip form construction2.1Slip form constructiona. ConcreteThe concrete adopted for this job will be ready mixed concrete. The following data shall be noted in the plan sheet: pouring and vibrating time, pouring section, strength requirement, slumps and the quantity (

8、cubic meters) intended to be poured and planned time of pouring. When slipform starts, the concrete shall be continuous, and the masons follows to vibarte. The concrete will be put into formworks and vibrated at the same time from both directions, so as to avoid the occurrence of slots or cracks cau

9、sed by the already hardened concrete when only work to one direction. The proper slump requirement for slipform is 90-140mm. Concrete transportation: the concrete in the self-fabricated tipcart will be transported by the headframe to the sliding platform, and supplied to place of pouring by the tipc

10、art.Vertical transportation: After calculation, the capacity of the tower crane meets the actual transportation demand. At the same time vertical transportation of the concrete should meet the demand for different section, Therefore, three headframe, which could goes up with the platform, is needed

11、for silo wall sliding up, and self-fabricated tipcart, actually the capacity of the lorry is 0.18 cubic meters. Concrete pouring: when the silo wall is sliding up, put the concrete from the tipcart onto the platform between two slip form supports, masons shovel all the concrete on the platform into

12、the formwork, masons following to vibrate the concrete. The concrete shall be continuously, and put into formworks and vibrated at the same time to both directions, so as to avoid the occurrence of slots or cracks caused by the already hardened concrete when only work in one direction.After put the

13、concrete into the formwork, vibrate it in time with poker vibrator. The working principle is “quick insert and slowly pull out”, “one vibrator after another”, “vibrating in parallel”. For each point, the vibrating time is 20s-30s, the vibration could not be stopped only when the concrete surface doe

14、s not go down obviously, and there is no air bubble comes out, and thick liquid occurs on the concrete surface. When vibrating the upper layer, the insert to the lower layer could not more than 5cm and connection joints between these two layers shall be eliminated. No vibration and over vibration is

15、 forbidden.When concrete is delivered, slump should be checked. The proper slump for slip form construction is 90-140mm.Records must be taken and kept for the strength test, and mark out the pouring section and strength etc. The concrete shall be crushed at 7 and 28 days. When results are satisfacto

16、ry, the documents shall be kept in the archives. As for the disqualified cubes, the reasons have to be found out and actions for that batch have to be taken.b. ReinforcementThe vertical rebars lapping shall staggered at 1/4, and the overlapped area of ring horizontal rebars shall be no less than 50d

17、. when the overlapping joints staggered distance is longer than 1000, then one rebar could be overlapped in the same area every four pieces. The rebars above the door and of the silo wall shall be bond when sliding up, the binding works shall be done with the concrete grouting one after the other.Th

18、e concrete cover and position of the rebars are ensured to be correct by the clips installed in the horizontal beam of the slip form supports.c. sliding-upPreliminary sliding-up: when begin with silo wall grouting, the concrete shall be grouted in 3 layers into the formwork of 1200mm on both directi

19、ons. Try to slide up the wall after 4 or 5 hours with 2 to 4 courses. Test the concrete out of the formwork with hand, when there is only a slight fingerprint and the concrete does not stick to the hand, then the normal sliding up procedure could be carried out after a short break.After completion o

20、f the soleplate construction, the above-mentioned method shall be taken for the grouting of upper silo wall. Attention:When start constructing silo wall above the soleplate, please pay attention to see whether the concrete strength of the soleplate meet sliding-up requirement because the sliding-up

21、will start immediately after finish soleplate grouting works. If the concrete is not strong enough, the sliding-up speed shall be decreased. Normal sliding up: each time sliding up 30cm, the concrete shall be grouted circularly on both directions. It shall be lifted at an interval of 1.5-2.0 hours,

22、and when the temperature is high, it could be lifted 1-2 courses additionally. Whenever sliding up, correction works has to be done to avoid excursion and torsion, in case the deviation of the plummets for excursion and torsion controlling exceed 15mm (generally if any deviation occurs), correction

23、works shall be done. Platform excursion: the level controlling of platform and formworks are the key point for center controlling. Before sliding up the formworks, the whole platform and the level of the jack must be checked and corrected by water level. The support shall be checked by water level a

24、s well, it shall be checked every other grouting.Deviation of the platform shall be corrected by inclining, lift the jack on the deviated side to a proper height and sliding up when the platform is inclined (no more than 1%), after the deviation has been corrected, continue with normal sliding proce

25、dure. Platform torsion: torsion of the platform shall be corrected by dragging, 8 points shall be selected evenly along the periphery and dragged by manual hoists to the opposite direction of the torsion, the torsion will be corrected when lift up the formwork.Attention:The poles must be reinforced

26、when lifting up the platform without concrete.Stop sliding: when the sliding up must be stopped due to construction necessity or special cases, it shall be lifted up 1-2 courses at an interval of 0.5-1.0 hour, until the formwork and concrete do not stick together (around 4 hours), and it shall be li

27、fted up 1 course the next day.Special record sheets have been taken for this job for technical controlling of every item, detailed information see attachment.d.Embedded parts and openings: on the sliding platform, nameplates shall be installed for all the embedded parts and openings and marked the c

28、ode of embedded parts, size, and elevation data, and one person shall specially manage these nameplates.Attention:During construction there are much more iron parts and openings, therefore, the responsible person of the platform shall review and check the drawing and construction markings carefully
