Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1, the new epeirogenetic of this rubble mounding for sea-reclamation long spire pilot hole add the construction method of hammer piling, comprising steps of
S1: it is drilled, is drilled into default in the default pile sinking position for presetting new land by full-sleeve long-spiral drilling machine
Pile sinking height；
S2: default tubular pole is hammered to the default pile sinking height in the drilling of default pile sinking position by Driven Piles machine.
Pass through drilling machine on the ground at default pile sinking position in new epeirogenetic to drill, backfill layer in new epeirogenetic ground be drilled, in turn
Facilitate and tubular pole is sunk into default pile sinking position, facilitate pile sinking, prevents the intensive or biggish rock for backfilling layer in new epeirogenetic ground
Influence sinking to for tubular pole.
As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 8, further, step S1 includes:
S11: default pile sinking position is obtained；
S12: obtaining default tubular pole diameter, chooses corresponding drill bit according to default tubular pole diameter；
S13: according to the thickness of the new epeirogenetic ground jackstone backfill layer of rubble mounding for sea-reclamation, corresponding pilot hole steel sleeve is selected；
S14: adjustment drilling machine, bit location, so that bit location vertically stands on default pile sinking position；
S15: default pile sinking height is obtained, is drilled at default pile sinking position；
S16: it is drilled at default pile sinking position to default pile sinking height.
The diameter that pile sinking position and pile sinking height and tubular pole are determined according to the size of design drawing when pile sinking position, sinks
After stake height and tubular pole diameter determine, corresponding drill bit is chosen by the diameter of pile sinking height and identified tubular pole and is drawn
Drill bit and the rigid casing of pilot hole are built at default pile sinking position by hole steel sleeve vertically, and pilot hole steel sleeve is sheathed on brill when drilling
On head and the two rotates sinking simultaneously, and soil block, rock rise delivery port with helical blade, until drilling depth reaches and presets
Pile sinking height is mutually simultaneously stopped.
Further, step S16 further include:
S161: borehole perpendicularity is detected when drilling to 0.5m to 1m depth；
Judge whether borehole perpendicularity is vertical；
Depth is corresponded to as default pile sinking height if so, continuing downward pore-forming, if it is not, stopping pore-forming and repeating step
S14。
When drill bit and pilot hole steel sleeve drill, then the depth of 0.5~1.0m of subdrilling detects the verticality of institute's drilling bore hole,
If the verticality of drilling meets the requirements, drill bit and pilot hole steel sleeve work on, if the verticality of drilling is undesirable,
It then needs to readjust the angle at drill bit and default pile sinking position, prevents drilling run-off the straight and lead to not pile sinking.
Further, step S16 further include:
S162: drill bit, pilot hole steel sleeve are taken out when depth of pore forming reaches default pile sinking height；
S163: detection check borehole depth, bore diameter and borehole perpendicularity；
S164: in backfilling in drilling into rubble.
After jackstone backfill layer completes drawing hole construction, to avoid closing on the influence of stake position drawing hole construction, and stake position is closed on
The influence of subsequent hammer piling, while in order to avoid pilot hole collapse hole and security risk is reduced, stake is carried out using small particle gravelly soil
Hole backfill, to reinforce the finished product protection to drilling, the diameter of small particle gravelly soil should can guarantee in 10mm between 50mm
Drilling will not collapse, and can not influence tubular pole and sink to.
As shown in Fig. 5, Fig. 6, Fig. 7, further, step S2 includes:
S21: corresponding Driven Piles machine is selected according to default tubular pole diameter；
S22: adjusting Driven Piles seat in the plane and set, so that Driven Piles machine is vertically stood on above bore position；
S23: default tubular pole is put into drilling；
S24, tubular pole is pushed by Driven Piles machine.
After selecting corresponding hammering to install according to default tubular pole diameter, Driven Piles machine guide rod is adjusted, is allowed to perpendicular to default
At pile sinking position, then tubular pole is lifted by crane, tubular pole lower end aligned drill center is inserted just, while being mutually 90 degree with two theodolites
Angle, cooperation Driven Piles machine align stake, manage drilling, Driven Piles machine and tubular pole will by Driven Piles machine in after a vertical line
At stake indentation to default pile sinking position；
Further, step S24 includes:
S241: tubular pole is depressed by Driven Piles machine vertically downward；
S242: judge whether default tubular pole plan-position is in pre-determined stability state；
S243: default tubular pole is continuously beaten, until default tubular pole falls into presetting in drilling and sinks if so, hammering and filling the machine that hits
Stake height.
Driven Piles prow first presses downward to tubular pole, so that tubular pole keeps vertically being pressed into drilling under the pressure of Driven Piles machine
It is interior, static pressure type pile sinking is carried out, after the plan-position of tubular pole, verticality obtain correctly adjusting and stablize, enables tubing vertical
Be inserted into drilling, guarantee tubing it is subsequent continuously hammered when inclination in angle will not occur, recurrence is connected with Driven Piles machine
Continuous strike tubular pole, carries out paddle type mill pile sinking.
Further, step S243 includes:
S2431: hammering impinges upon when continuously beating default tubular pole, real-time judge tubular pole remain high height whether be less than it is default
Limiting altitude；
S2432: if so, welding another default tubular pole in default tubular pole upper end, and step S241 is repeated, until tubular pole height
It is consistent with default pile sinking height.
In construction, default pile sinking height is higher, such as, with high tubular pole, is easy to cause tubular pole using with default pile sinking height
Run-off the straight during hammering, and the working depth of Driven Piles machine requires also increase accordingly, and leads to cost and difficulty of construction
Increasing continuously hammered to tubular pole upper end in a upper tubular pole and do not fallen within drilling so the tubular pole for needing to select length shorter
When interior height is identical as predetermined limit height, stops hammering and welding accesses another tubular pole in tubular pole upper end, then repeat
Step S241, until tubular pole height is consistent with default pile sinking height.
Tubular pole, which remains high predetermined limit height, should be 500mm, when pile extension, remove completely to welding position, with mechanical
Derusting executes " steel-pipe pile flux-cored wire CO2 Welding Machine Welder to welding current, voltage, speed of welding etc.
Skill regulation ", interface position deforms if any clashing and breaking or has local damage deformation after hammering, burr occurs etc., it to be modified, close
It is welded again after lattice, pile extension counterpart misalignment should be less than 2mm, and local gap should be tamped greater than 2mm's using steel plate.
Pile extension throat depth increases 2mm than conventional, and weld seam answers continuous full, appearance pore-free, slag inclusion, stings meat depth
Less than 0.5mm and it should be less than a quarter of full circumference, postwelding removes slag, after pile extension weld, waits 3 minutes necessary cold
But time, the epoxide coal bituminous anti-decaying paint of pile extension position brushing quick-dry type of tubular pole, again into indentation tubular pole operation after parching.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
Generation, defined range that however, it does not deviate from the spirit of the invention.
