Description
Technical field
The invention belongs to foundation pit enclosure pile construction technology field, stake work is planted in more particularly to a kind of drilling high pressure draught vibration
Skill and prefabricated pile.
Background technology
Precast concrete pile is prefabricated in the factory shaping, by the side such as hammering, static pressure or prebored hole after transport to job site
Formula is implanted into stratum, good with pile quality, and speed of application is fast, the features such as high financial profit, in the construction of building and structures
On be widely used.Pile body is implanted into stratum by hammering and static-pressure pile planting by ambient pressure, mud-less pollution in work progress, construction
Place Green civilization.
Meanwhile, there is some defects and deficiency in existing prefabricated pile pile sinking process：
1) it is larger to ground perturbation during stake lower using hammering vibration, and there is problem of noise pollution, be not suitable in residential block
And school area construction；Stake although noise without friction under Static pressure pile driver, but soil compaction effect is there is also, there is shadow to ground and adjacent stake
Ring.
2) prebored hole joints cement soil is planted the technique of stake and needs the cooperation on slurrying backstage, stirring concrete earth complex process, when
Easily efficiency of construction is influenceed when slurrying backstage goes wrong.
Even if it is not enough fundamentally to solve these using the plant piling method that prebored hole and vibrating static-pressure are combined.
The content of the invention
In order to overcome the deficiencies in the prior art, stake technique, the work are planted the invention provides one kind drilling high pressure draught vibration
First with drill hole of drilling machine in skill, with the discharge part soil body, then secondary drilling is carried out by mixing pile machine, effectively prevent soil compaction effect
Should, and then the influence to ground and adjacent stake is avoided, meanwhile, by being passed through for cement grout, without backstage coordinative construction, construction
Program is simplified.
The concrete scheme of the non-bearing type water tank for water heater is as follows：
Stake technique is planted in one kind drilling high pressure draught vibration, including：
1) using after rig pore-forming to set depth, the soil body is discharged；
2) using mixing pile machine in step 1) continue on the basis of hole to drill, and cement grout, water are injected in hole
Slurry liquid is mixed to form cement grout with the soil body in hole；
3) by prefabricated pile implantation step 2) in hole in.
In above-mentioned technique, by rig elder generation pore-forming, the soil body is discharged, then continue to drill by mixing pile machine, and in mixing pile
During machine drill hole, without discharging the soil body, to cement grout is injected in hole, cement is mixed to form water with the soil body in drilling
Soil slurries, intensity is more than the soil body after cement grout solidification, and intensity is high, and can be used to fill between drilling and prefabricated pile
Space, it is ensured that the stability of prefabricated pile supporting, cement grout is stirred without backstage again, simplifies work progress, meanwhile,
The presence of cement grout, effectively reduces vibration noise during stake is planted.
Wherein, in the step 3) in, during prefabricated pile is implanted, high pressure is exported by the pile top of prefabricated pile empty
Gas, to the resistance of prefabricated pile, is smoothed out plant stake process to reduce cement grout in hole, can accelerate to plant stake speed, it is ensured that pre-
Bottom hole designed elevation is smoothly sunk in stake processed.
In order to realize being passed through for high pressure draught, longitudinal direction is embedded with air delivering pipeline, air delivering pipeline top in the prefabricated pile
Portion can be connected with air compressor, and air delivering pipeline is set from prefabricated pile top to pile top, and high pressure draught is passed through by pile top, is reduced
Resistance between prefabricated pile and cement grout.
When prefabricated pile is single-unit stake, the air delivering pipeline is one；When prefabricated pile is more piece stake, the air delivering pipeline
The air hose in the stake of each section is distributed in including multistage, adjacent air hose is attached by connector.
In order to improve early stage drilling efficiency, the step 1) in rig be twist bit.
The pre-buried wireway of pile top of the prefabricated pile, wireway is connected with described air delivering pipeline, and the wireway is can
The wireway of longitudinal extension；Wireway is divided to two sections, is connected with air delivering pipeline in a section embedment pile top, and another section is scalable.Plant stake
When wireway stretch out high pressure draught exported outside stake, plant stake by pile body gravity and high pressure draught impact cement grout, pile body is reached
After designed elevation, pile body and pressure of the hole in the bottom are by portion in wireway jacked pile body.
Further, to prevent cement grout during lower stake from causing blocking into wireway, air guide tube side part is provided with outlet
Hole.
In order to coordinate above-mentioned construction technology, present invention also offers a kind of prefabricated pile for being passed through high pressure draught, this is pre-
Stake processed can be passed through high pressure draught, effectively reduce the resistance planted during stake, reduce and plant the noise that stake is produced, and the prefabricated pile can also
It is applied in other construction of prefabricated piles techniques.
A kind of prefabricated pile for being passed through high pressure draught, including pile body, pile body inside set the appendix of longitudinally through pile body
Road, air delivering pipeline top be connected with air compressor with by air delivering pipeline to pile top conveying high-pressure gas.
The pile body pile top sets telescopic wireway, and wireway is connected with described air delivering pipeline.
During lower stake, liquid blocks wireway in the soil body or drilling, and the wireway is provided with venthole,
Venthole is located at the both sides of wireway.
When prefabricated pile is single-unit stake, the air delivering pipeline is one；When prefabricated pile is more piece stake, the air delivering pipeline
The air hose in the stake of each section is distributed in including multistage, adjacent air hose is attached by connector.
Compared with prior art, the beneficial effects of the invention are as follows：
1) present invention by substep drilled, early stage can discharge part drilling in the soil body, coordinate cement grout, it is to avoid
Soil compaction effect, and then avoid the influence to ground and adjacent stake.
It is 2) of the invention by the way that to cement grout is injected in hole, cement is mixed to form cement grout with the soil body in drilling,
Cement grout simplifies work progress without backstage coordinative construction, meanwhile, the presence of cement grout, during stake is planted
Effectively reduce vibration noise；Additionally, the mud intensity of the general retaining wall of soil cement slurry liquor ratio is big, concentration is sticky, after solidification can with it is pre-
Stake processed forms compound pile body, enhances the stability of pile body.
3) present invention is passed through high pressure draught by during stake is planted, and effectively reduces in hole cement grout to prefabricated pile
Resistance, make plant stake process be smoothed out, improve prefabricated pile plant stake efficiency, meanwhile, the effect of high pressure draught is also effectively reduced
Plant the vibrating noise during stake.
