Description
Technical field
The present invention relates to technical field of civil engineering, are specifically related to a kind of intelligent construction method for planting stake.
Background technology
In field of civil engineering, traditional construction of prefabricated piles mainly has hammering method and static pressure method, both modes are deposited
The problems such as penetrating resistance is big, speed is slow, soil compaction is serious, to the building on periphery, pipeline and structure during construction of prefabricated piles
It builds object and generates harm.Although taking some stress release measures that can alleviate the harm of soil compaction, this soil compaction facts have proved
Harm is difficult to eliminate.In addition, formation resistance is bigger, need the pressure of pile sinking bigger, leads to damage of the pile driving process to pile body just
It is bigger.In order to protect pile body without damage in work progress, it is necessary to using the piling compared with high-bearing capacity so that the cost of pile foundation
Increase very much.Another method is pilot hole drag reduction, and this not only adds construction costs, although and pilot hole drag reduction, also reduce
The side-friction force of foundation soil, leads to the reduction of bearing capacity of pile foundation, to increase project cost.
In mud class soft layer, since the frictional resistance of the soil body is relatively low, cause the side bearing capacity of pile body smaller so that
The intensity of pile shaft material does not play effect, cannot fully apply, and generates larger waste.
Prefabricated pile enters decomposed rock and is currently impossible across dense sand stratum, to limit the application range of prefabricated pile.
For the region of surrounding enviroment complexity, it can only use cast-in-situ bored pile, cast-in-situ bored pile in the construction process will production
Raw a large amount of slurry coat method and pore-forming pulping will generate pollution to environment.Simultaneously as the quality of concrete placed under water is difficult to
Ensure and the mudcake on drill-pouring pile body periphery causes pile body bearing capacity to decline so that the cost of cast-in-situ bored pile is than prefabricated pile
Cost is high by 40% or more.
It drills in sandy gravel stratum, borehole cleaning is very difficult, so that the construction time of cast-in-situ bored pile and cost is increased more.
The problem of being haveed the advantages that based on prefabricated pile basis and bored pile foundation and respective, the highly desirable general of engineering circles
The advantages of this two kinds of pile foundations, develops, overcome its there are the shortcomings that, need to innovate a kind of pile foundation construction equipment.
Invention content
Technical problem to be solved by the present invention lies in overcome problems of the prior art, provide a kind of intelligence
Plant pile construction method.
A kind of intelligent plant pile construction method, includes the following steps:
(1) fluidised form solidified earth is formed
1) slurries are configured:
Slurries parameter is inputted in the pulp feeding system of backstage, carries out River Bank Stability automatically;
2) construction mixing pile:
Construction parameter is inputted in the intellectualizing system of mixing pile construction equipment, using the drilling rod with upper and lower mouth spray,
Soil body aliquot replacement in stake holes, stir in situ are formed fluidised form solidified earth by lower brill construction;In drilling process, upper mouth spray spray
The slurries gone out by the blade on drilling rod further with soil shear failure;After inputting construction parameter, whole process automated construction;
(2) it is implanted into prefabricated pile:
It is implanted into prefabricated pile body in fluidised form solidified earth, prefabricated pile body is docked by more piece, and it is solid that previous section pile body is inserted into fluidised form
Change in soil and reserved banjo fixing butt jointing, later section pile body are lifted by crane and docked with previous section pile body, prefabricated pile is continued into after docking
Body forms composite pile until all prefabricated piles are all implanted into;
Cycle construction mixing pile, implantation prefabricated pile successively, form more composite piles.
Lower in step 2) to bore construction, detailed process is as follows:
A) drilling rod stirring is sunk, and is sunk since stake top absolute altitude h1, and lower mouth spray opens whitewashing, lasting whitewashing stirring to stake
Bottom h3;
B) drilling rod stirring is promoted to h2 from h3, and mouth spray is descended to whitewash in the process;
C) drilling rod stirs again from h2 and sinks down into a bottom h3, does not whitewash in the process, pure stirring;
D) drilling rod stirring is promoted to h2, in the process upper mouth spray whitewashing;
E) drilling rod stirring is promoted to stake top absolute altitude h1, and upper mouth spray continues to whitewash in the process.
When stake top absolute altitude is ground elevation, h1 0.
When stake top absolute altitude is located at ground elevation or less, need to fetching earth within the scope of stake top to ground elevation, drilling rod
Upper corresponding position is provided with helical blade, and helical blade takes out the soil body in stake top h1 to 0 range of ground elevation, and stake top
It does not whitewash within the scope of to ground elevation.
E) in step, when drilling rod stirring is promoted to stake top absolute altitude h1,0-3 meters can be shifted to an earlier date and close upper mouth spray whitewashing.
Drilling rod course changing control is as follows:
Drilling rod stirs since stake top absolute altitude h1 and sinks down into a bottom h3, and drilling rod rotates forward;
By being carried in the h3 stirrings of stake bottom to h2, drilling rod inverts drilling rod in the process, then stirs sink down into a bottom again, and drilling rod rotates forward;
Drilling rod is promoted to h1 sections by stake bottom h3 stirrings, and drilling rod first inverts, and when needing progress stake top to fetch earth, drilling rod rotates forward.
Implantation construction of prefabricated piles is immediately begun to after mixing pile construction, the construction time of every prefabricated pile is small less than 1.5
When, it plants pile driving construction overall process and carries out measuring for verticality and adjustment.
In step (2), the connection of prefabricated pile body using mechanical connection or is welded to connect.
In prefabricated pile docking operation, previous section prefabricated pile end is clamped using a pile follower equipment, then later section stake with
It is docked, and after docking, is unclamped the end clamping of previous section prefabricated pile, will be docked using prefabricated pile gravity or application pressure
Prefabricated pile implantation afterwards.
It configuring in slurry processes, backstage pulp feeding system is weighed stirring automatically according to the slurries total amount of setting, the ratio of mud, and oneself
Trend mixing pile construction equipment is for slurry.
Advantageous effect:Compared with prior art, using upper and lower mouth spray combination by the way of whitewash, can make whitewashing with
The soil body is adequately stirred, and especially upper mouth spray, when drilling rod above carries, slurries are stirred blade and are stirred, at reinforcing
Weak soil basis is managed, uniform intensity, uniform density, higher bearing capacity and preferable water-stagnating effect, construction is made it have and makes
Valence is low, and full automatic backstage pulp feeding system so that dust pollution is controlled in work progress, and non-environmental-pollution is environmentally protective.
