Abstract
The present invention relates to pile foundation construction.Percussion Piles wall protecting method in soft sandy ground matter, it includes：Step 1, each stake position is gone out according to blueprint measuring at the scene, mark is carried out at stake position；Step 2, the place for intending construction stake is carried out with digging machine or forklift to roll smooth compacting, ensures the compactness of top sandy soils, rolled while cover the thick clays of one layer of 30cm, be embedded into sand top layer, make surface-closed；Step 3, it is different according to stake footpath at stake position, 2 ~ 3 meters of long steel pile castings are installed, casing diameter is more than stake footpath 10cm, and casing bassets 200 ~ 300mm；Step 4, using stake position center as the center of circle, casing is border, carries out mortar depositing construction in the range of 1 times of stake radial width outside casing, and slip casting depth is depending on weak sandy soils thickness；Step 5, slip casting are conserved after terminating, and the formal Percussion Piles construction stage is transferred to after reaching some strength.The present invention effectively solves the problems, such as that Percussion Piles hole wall easily caves in weak sandy soils.
Description
Technical field
The present invention relates to punching pile construction method in pile foundation construction, more particularly to soft sandy ground matter.
Background technology
In deep weak sandy strata, when design uses impact holing stake, due to the soft givey spy of sandy soils
Property, in punch process, vibration caused by tup impact stratum is sprung up with slurry fluid, hole wall can be produced compared with large disturbances,
1.5 ~ 2 meters of long steel pile castings generally are used in construction, prevent hole wall sand caves in from causing buried via hole accident.But work as weak sand soil layer
When thickness is larger, conventional 1.5 ~ 2 meters of steel pile casting can not meet the needs of site operation, and if using casing is greatly enhanced, then
Must be by means of the equipment such as big machinery, vibration hammer, mechanical arm, and degree control also more difficult grasp.
The content of the invention
A kind of present invention seek to address that drawbacks described above, there is provided Percussion Piles wall protecting method in soft sandy ground matter.The present invention can have
Effect solves the problems, such as that Percussion Piles hole wall easily caves in weak sandy soils.
To solve the above problems, Percussion Piles wall protecting method in soft sandy ground matter, it includes：
Step 1, each stake position is gone out according to blueprint measuring at the scene first, obvious mark is carried out at stake position；
Step 2, the place for intending construction stake is carried out with digging machine or forklift to roll smooth compacting, ensures the closely knit of top sandy soils
Degree, roll while cover the thick clays of one layer of 30cm, be embedded into sand top layer, make surface-closed；
Step 3, it is different according to stake footpath at stake position, 2 ~ 3 meters of long steel pile castings are installed, casing diameter is more than stake footpath 10cm, casing
Basset 200 ~ 300mm；
Step 4, using stake position center as the center of circle, casing is border, progress slip casting is applied in the range of 1 times of stake radial width outside casing
Work, slip casting depth is depending on weak sandy soils thickness；Slurries are mainly mixed by cement and chemical paste, waterglass；
Step 5, slip casting are conserved after terminating, and the formal Percussion Piles construction stage is transferred to after reaching some strength.
The present invention is hardened layer of sand closed upper part grouting behind shaft or drift lining using cohesive soil, prevents that slurries are altered from layer of sand surface during slip casting
Go out, improve grouting consolidation effect；Effectively solve the problems, such as that Percussion Piles hole wall easily caves in weak sandy soils.After grouting and reinforcing,
The operation side after hardening can be provided for follow-up Percussion Piles stake machine erect-position and machine-walking and personnel's operation, be advantageous to civilization
Construction.Cost of the present invention is low, and method is simple, material therefor goods and materials, is easily to obtain conventional goods and materials.
Embodiment
Percussion Piles wall protecting method in the soft sandy ground matter of the present invention, it includes：
Step 1, each stake position is gone out according to blueprint measuring at the scene first, obvious mark is carried out at stake position；
Step 2, the place for intending construction stake is carried out with the machinery such as digging machine or forklift to roll smooth compacting, ensures top sandy soils
Compactness, roll while cover the thick clay of one layer of 30cm, be embedded into sand top layer, make surface-closed；
Step 3, it is different according to stake footpath at stake position, 2 ~ 3 meters of long steel pile castings are installed, casing diameter is more than stake footpath 10cm, casing
Basset 200 ~ 300mm；
Step 4, using stake position center as the center of circle, casing is border, progress slip casting is applied in the range of 1 times of stake radial width outside casing
Work, slip casting depth is depending on weak sandy soils thickness；Slurries for cement and chemical paste, waterglass mainly by mixing；
Step 5, slip casting are conserved after terminating, and the formal Percussion Piles construction stage is transferred to after reaching some strength.
