Description
Technical field
It is particularly a kind of the invention belongs to Geotechnical Engineering field, more particularly to prestressed concrete pipe pile field
It is new it is prefabricated can drainage tubular pile and its prepare construction method.
Background technology
Recently as developing rapidly for China's economy, engineering of reclaiming fields from the sea, Storage Yard Project, highway builds work
Journey scale amounts are all sharply increased, and this class is coastal, along the lake, the weak soil problem that runs into riverine engineering becomes engineering construction
In have to the problem that faces.The main soft-soil foundation treatment method of current China has：Draining concretion method, heavy-tamping method, lime pile
Method, vibroreplacement, reinforcement local method, sinking tubular gravel pile method etc..But for some more deep Soft Soil Layers, above processing side
Method is extremely difficult to expected treatment effect.
Pile for prestressed pipe is high because of its industrialized production degree, and self-strength is big, and penetration power is strong, and bearing capacity of single pile is high, construction
Cycle is short, and effect on environment is small, is widely used the advantages of low cost in deep soft soil foundation processing, economic and social benefits show
Write.But pile for prestressed pipe as a kind of prefabricated pile squeezes into the soil body and carrys out soft soil foundation and still has some problems, specific table
It is now the following aspects：(1), in pile for prestressed pipe pile driving process, pile body occupies original sky of the soil body on its locational space
Between, especially when stake week is saturated soft soil, soil compaction effect substantially, easily causes its surrounding soil and destroyed, the phenomenon such as local eminence；
(2), in pile for prestressed pipe pile driving process, pile peripheral earth is squeezed by densification, cause it is adjacent be driven into pile body occur it is larger vertical and
Horizontal displacement, seriously results even in pile body and fractures；(3), caused super quiet pore water in pile for prestressed pipe pile driving process
Pressure value is larger, sometimes even over overlying stress and dissipates slow.Many scholars have developed a series of new based on this
Drainage tubular pile, such as：A kind of adaptive pressure-reducing drainage pipe pile of the research and development such as the Zhong Mei states of the patent No. 201110123235.6 hero professor；Specially
A kind of drainage tubular pile of the research and development such as small celebrating of Xu in profit number 201020649772.5；Tang Xiao forces etc. in the patent No. 201510150002.3
It has developed a kind of energy draining and increase the prefabricated tubular pile of frictional resistance.Such novel tubular pile is all by reserved laterally in pile body side wall
Hole provides drainage path, but soil particle can enter drainage channel and block default row in actual drainage procedure at the scene
Water route, actual Effect of Ground Treatment is unsatisfactory.In view of problem above, one kind slows down soil compaction effect, accelerate excess pore water pressure
The novel tubular pile of dissipation is urgently developed.
The content of the invention
In order to solve the above problems, the invention provides one kind it is new it is prefabricated can drainage tubular pile and its prepare construction method come
Slow down the soil compaction effect in pile driving process, accelerate pore water pressure dissipation and consolidation.In order to achieve the above object,
The present invention includes：Prefabricated tubular pile pile body, stake surface longitudinal and horizontal reserved groove, pervious concrete layer, corresponding tubular pile end
Plate etc..
As preferably it is described it is new it is prefabricated can drainage tubular pile by prefabricated concrete pipe pile pile body, pile body vertical and horizontal
Groove is reserved, pervious concrete layer, corresponding pile end board etc. is constituted, and its pile body outer wall relevant position is reserved with vertical and horizontal
Groove, groove width is 50-150mm, and groove depth is 10-20mm.
Isometric as the longitudinal fluting and pile body described in preferably, transverse concave groove is annular, laterally recessed around pile body outer wall
Its designed elevation of groove can be according to soil layer actual conditions Position Design, and this case is arranged in arranging at the longitudinal quarterline of pile body.
As being filled up in preferably described reserved groove by pervious concrete filling, pervious concrete is by 80% particle diameter
1.25-2.5mm aggregate, 20% particle diameter forms for 2.5-5mm aggregate mixing, and the ratio of mud is 0.3 and with the addition of in right amount early strong
Agent and water reducer.
As preferably described pile end board, it is left in slightly large-sized emptying aperture, emptying aperture with pile body groove correspondence position fills out
Filled with permeable geotextile, the fixed geotextiles of wire netting sealing are set on the outside of pile end board.
By above technical scheme, usefulness of the present invention has：
1, the wide 50-150mm reserved to prefabricated tubular pile pile body side wall vertical and horizontal relevant position, deep 10-20mm's is recessed
Filling pervious concrete provides passage for the discharge of inter-pile soil body pore water in groove, can accelerate pore water pressure dissipation and
Consolidation, effectively slows down soil compaction effect.
2, the present invention can avoid the phenomenon that the rise of piling process Pore Pressure causes pile peripheral earth to swell.Simultaneously can be with
Reduce vertical and horizontal displacement between adjacent pile body, it is to avoid the stake end caused by neighbouring pile body pile sinking is hanging, deflected file, pile body
The phenomenon such as fracture.
3, the present invention can effectively improve the mechanical property of inter-pile soil body and the bearing capacity of pile foundation, reduce settlement after construction and negative
Frictional resistance.
4, the reserved groove of lateral loops stake of the present invention can be positioned according to soil layer actual conditions, flexible, be had conscientiously
Effect.
5, the pile end board that the present invention is designed in the emptying aperture with pile body drainage channel correspondence position by inserting permeable geotechnique
Fabric is simultaneously blocked with wire netting, it is ensured that drainage channel is unimpeded after pile extension, and actual drainage effect is good.
6, the present invention provide it is a kind of it is new it is prefabricated can drainage tubular pile it is simple in construction, can factorial praluction, efficiency of construction height,
Ambient influnence is small, and Foundation Treatment Effect is good, and economic results in society are notable.
