Description
Technical field
The present invention relates to interior casing mounting technique field, specially a kind of interior casing mounting process.
Background technology
In cast-in-situ bored pile, steel pile casting is often buried to position the stake position for needing to bore.Casing is steel pile casting, wall thickness 10mm,
When casing positions, first using stake position center as the center of circle, casing position is made on soil according to casing radius, after casing is in place, is applied
Casing is embedded to about 50cm by pressure.Difficulty is such as pushed, can the soil body at the position of hole first be dug out into a part, then place casing embedment
Underground.It should check whether casing is vertical during embedment, if finding deflection, should correct in time.Land casing bury put it is in place after,
It will be compacted with clay backfilling on the outside of casing, to prevent casing surrounding from drainage occur, backfill thickness about 40-45cm, top is high
Degree is higher by (water surface) ground 0.4-0.6m, and cylinder position is not greater than 50mm far from hole heart deviation；The cylinder s buried depth should be wanted according to design
It asks or the hydrological geological conditions of stake position determines, be not less than 1.0m in clay, be not preferably less than 1.5m in sandy soil, ordinary circumstance is embedding
Depth is preferably 2 ~ 4M, and special circumstances should deepen to ensure being smoothed out for drilling and concrete perfusion.There is the riverbed for washing away influence,
It should sink and be not less than 1.0 ~ 1.5M below people's local scour line.It is influenced or the cast-in-situ bored pile of underwater construction by fluctuation in stage, casing
Height should increase intensification, should squeeze into impermeable stratum when necessary.
Interior casing mounting process is complicated on current steady stake platform, and installation rear stability is poor, and shock resistance is poor.
Invention content
The purpose of the present invention is to provide a kind of interior casing mounting process, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides the following technical solutions：A kind of interior casing mounting process, including following step
Suddenly：
A, first steady stake platform is assembled, then whole to sling submerged, steel-pipe pile is sunk to sea by steady stake platform by dead weight
The certain depth of bed；
B, selectively apply certain vibration to steel-pipe pile top, by steady stake platform erection；
C, the card key of a steel-pipe pile is dismantled, gradually card key adjusting screw is unclamped simultaneously to discharge the pressure that steel-pipe pile is born, incites somebody to action
Steel-pipe pile vibration hammer or jump bit are squeezed into scar, in place after, again by the card key of the steel-pipe pile connection install；It repeats
Above procedure one by one squeezes into each steel-pipe pile；
D, it will be squeezed into scar across the interior casing of steady stake Platform center cylinder with hydraulic impact hammer；
E, steady stake platform lock-screw suitable for reading is pre-tightened, the suitable for reading and platform of interior casing is made to be linked together；
If F, the driving depth of interior casing with it is expected that it is quite different, cause the opposed platforms suitable for reading of interior casing it is suitable for reading height
Direction has exceeded the range of requirement, hangs steady stake platform with crane, gradually unclamps the adjusting screw of each card key, then remove card
Key, slinging steady stake platform makes its height along all six steel-pipe piles up or needed for lower slider, and new position again by
A installation card key fixed platform.
Preferably, further include following steps：Interior casing and steel-pipe pile must control swashing for vibration hammer when squeezing into scar
Power of shaking makes interior casing and steel-pipe pile reach required bottom bearing, and the bottom bearing of steel-pipe pile reaches 2000KN；The bottom bearing of interior casing
Up to 3000KN.
Preferably, the basil of the interior casing and steel-pipe pile is all made of the high-strength wearable steel making of thickening.
Compared with prior art, the beneficial effects of the invention are as follows：The mounting process that the present invention uses can improve shock resistance
Performance improves subsequent construction efficiency；In addition, in the present invention, the basil of interior casing and steel-pipe pile is intended to use the high-strength resistance to of thickening
It grinds steel to make, can be absorbed impact when to enter rock, and dig out certain contact surface in rock surface, ensure that reliable end is held
Power；In the present invention, interior casing uses hydraulic impact hammer pile sinking, it can be ensured that the bearing capacity of interior casing；In addition, interior casing and steady stake
It is pre-tightened by lock-screw between platform, is beneficial to casing height in the transmission and adjustment of bearing capacity.
Specific implementation mode
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work belongs to the model that the present invention protects
It encloses.
The present invention provides the following technical solutions：A kind of interior casing mounting process, includes the following steps：
