Description
Technical field
The present invention relates to technical field of buildings, it is related to a kind of pile base construction method for having more.
Background technology
Pile foundation is by stake and the single-pile foundation that connects the deep foundation that constitutes of pile framing of stake top or be connected by post with pile foundation, stake
Base is common building foundation.When existing pile base construction method is constructed, if ground top layer is flat field back fill course recently
When, rainwater influences in addition, under the effect such as muddy water, and place mud is solidifying thicker, causes disturbance during drilling-machine shifter to soil layer, stirs into
Mud, drilling-machine shifter is extremely inconvenient, or even can not move, and has to stop work or takes the measures such as place mat steel plate, has both added construction
Cost, again can not smooth construction, cause the disastrous effect of construction delays.
The content of the invention
Problem to be solved by this invention is to provide a kind of pile base construction method.
To achieve these goals, the technical scheme taken of the present invention is：A kind of pile base construction method, it is characterised in that
Comprise the following steps：
(1) positioning is measured to building according to red line requirement, measurement baseline, water is checked in relevant personnel such as first management
On schedule, control point, stake site and accreditation rear of signing can be used, the measurement control point provided according to construction unit and design drawing
Each position central point is demarcated in paper, measurement, is squeezed into bar dowel and is aided with eye-catcher, and measuring goes out site elevation, and measurement is fixed
Position achievement seeks ways to return sb.'s kindness management or construction unit checks and can start construction after examination signature confirms, measuring stake position error cannot be greater than
Survey crew should be checked bar dowel head before pile sinking in 20m, and work progress, made with avoiding pile sinking and stake machine from travelling
Into uplift of soil influence stake position accuracy, to construct after stake also want tracking observation two to three days, whether the judgement soil body
It is subjected to displacement, whether vibrations soil compaction effect is strong；
(2) stake machine moves on to finger fixed pile, before piling must by stake platform leveling, it is in place after stake is hung in pressure cap, it is ensured that
Hammer, cap, stake three-core check that the perpendicularity of stake and stake position are inclined to just in a vertical line, ensuring there is good contact between cap and stake top
Difference, treats perpendicularity within 0.5% and pile position deviation cannot be greater than 20m, paper washer thick dolly selection 100mm or plastics system
Product, it is to avoid stress concentration causes pile crown to damage, and changing in time, and it is low away from piling to follow weight, completes one and saves the heavy of stake
After stake process, pile extension is welded, second section, Section three etc. of pile driving process are repeated, so as to complete the work progress of a pile；
(3) pile foundation joint form uses joints made by electric welding, and when saving stake welding up and down, lower section pile crown bassets 50-100mm,
First 4-6 point of spot welding is answered to fix so as to welding operation, during pile extension, then two electric welders are symmetrically welded, and ensure weld seam
Quality and size；
(4) the stake top absolute altitude that design is wanted is sent to by the live absolute altitude measured in advance, its error is ± 5cm, should measure correction
Pile feeder perpendicularity, it is to avoid the eccentric compression moment of flexure unnecessary to pile cutoff, when pile follower or strike-on, answering in precheck pile tube is
No to be full of water, if being full of water in pipe, should first pump can just apply after the water of part；
(5) engineering pile ceasing driving standard strictly carries out dual control, and the 20-40mm that injection is located at code requirement is hit with last three gust 10
For main Con trolling index, pile top is referred into bearing stratum depth, scale has been indicated above Pile feeder, the pile follower later stage is by seeing
Measurement scales are examined, pile penetration is hit in calculate last three gusts 10, and fills in into construction note table；
(6) after a Construction of Engineering Pile is finished, pile tube aperture is blocked with the plank slightly larger than pile tube inwall, it is to avoid stake week
The soil body is fallen into stake holes, and then reuses the working procedure of the other engineering pile of same procedure progress until engineering terminates.
Beneficial effect：The pile base construction method before piling must by stake platform leveling, it is in place after stake is hung in pressure cap,
Ensure that hammer, cap, stake three-core, to just in a vertical line, ensuring there is good contact between cap and stake top, check perpendicularity and the stake of stake
Position deviation, treats perpendicularity within 0.5% and pile position deviation cannot be greater than 20m, paper washer thick dolly selection 100mm or modeling
Material products, it is to avoid stress concentration causes pile crown to damage, and change in time, and it is low away from piling, the section stake of completion one to follow weight
Pile driving process after, be welded pile extension.The pile base construction method improves construction mobility, effectively increases foundation pile construction efficiency.
