Description
Technical field
The invention belongs to technical field of building construction, and in particular to a kind of construction method for collapsibility soil body stake.
Background technique
Static pressure compaction pore-forming production pile foundation is usually used in collapsible loess foundation treatment process, existing static pressure compaction pore-forming
There are mainly two types of the methods for making pile foundation, and one is being perfused after immersed tube soil compaction, this method is to use Static pressure pile driver by rounded pencil
In shape steel pipe indentation soil, then into pipe concrete perfusion or other at pile material, extract immersed tube in perfusion；Another kind is to use
Pile for prestressed pipe is squeezed into and forms pile foundation in soil by the methods of static pressure or hammering.During making multiple pile foundations, when stake spacing
The collapsibility that cannot play the role of eliminating soil when larger needs the native stake of otherwise designed construction or lime soil pile with Compaction variables, phase
To duration longer higher cost, it is unfavorable for construction fugitive dust improvement；Stake spacing above two method when smaller, during soil compaction
The pile foundation for closing on completion of having constructed may be impacted, the pile foundation constructed generates the risks such as broken pile, deviation, cracking, therefore
The prior art needs further improve.
Summary of the invention
The purpose of the present invention is to provide a kind of Compaction variables can pour to form pile foundation or compound simultaneously in batches in advance
The construction method for the stake of the collapsibility soil body of ground reinforcement.
Based on above-mentioned purpose, the present invention is adopted the following technical scheme that:
A kind of construction method for collapsibility soil body stake, comprises the steps of:
(1) it upper section stake holes: squeezes to form upper section stake holes using static pressure compaction hole forming method；
(2) lower section stake holes:, which being drilled using long-spiral drilling machine through upper section, and continues soil rotary drilling downwards removes section drilling, shape
At stake holes；
(3) use pours material and is poured from bottom to top to the designed elevation of stake holes, material solidification to be poured, and forms stake.
Further, the length of the upper section stake holes is greater than collapsibility the thickness of the layer 1-2m.
Further, the horizontal plane of the length direction of the stake holes and ground.
Further, the stake in the step (3) is pile foundation or composite foundation reinforcement.
Use the method for above-mentioned preparation method batch making stake, which is characterized in that comprise the steps of:
(1) several upper section stake holes first are squeezed using static pressure compaction hole forming method；
(2) successively reuse long-spiral drilling machine through upper section drill and continue soil rotary drilling downwards remove section drilling, formation
Stake holes；
(3) use pours material and pours several stake holes one by one, and material solidification to be poured forms stake.
The present invention is forming several upper section stake holes using static pressure compaction hole forming method first when batch forms stake holes, due to
The length of upper section stake holes is merely greater than collapsibility the thickness of the layer 1-2m, therefore after first upper section stake holes is formed, in adjacent bit
When setting production second upper section drilling, since the length of its second upper section drilling is relatively short, to first upper section stake holes
Influence is smaller, while the present invention also uses long-spiral drilling machine successively to carry out secondary cutting one by one to several upper section stake holes, drills through down
Section drilling, long-spiral drilling machine are not only again corrected the aperture of upper section stake holes, prevent during secondary cutting
When making upper section stake holes using static pressure compaction hole forming method, adjacent upper section stake holes interacts the deformation of generation, influences stake holes
Size.In addition, using method of the invention can first batch making stake holes, poured in batches, greatly reduce the construction time,
Increase working efficiency.
