Description
Technical field
The utility model is related to Road Bridge Pile Foundation field, more particularly to a kind of pile with fluting and use reinforcing bar outside weld pile extension
High frictional resistance prefabricated tubular pile.
Background technology
The end of the sixties in last century, Fengtai Bridge Factory of the Ministry of Railways starts production pretensioned prestressed concrete pipe pile (referred to as
PC pile tubes), it was mainly used in the infrastructure of railway bridge engineering at that time；Development and production seventies post stressed concrete pipe
Stake.The need for adapting to port construction development, the boat of 1987 year traffic portion three office introduces prestressed high-strength coagulation from a Japanese full set
Native pile tube (abbreviation PHC pile tubes) production line.The later stage eighties, Ningbo East Zhejiang province cement products Co., Ltd closes with relevant scientific research institutions
Make, the characteristics of for China's Coastal Areas mud Unfavorable geology, by the transformation to PC pile tubes, develop pretensioned prestressing and mix
Solidifying soil thin-wall pipe pile (abbreviation PTC pile tubes).
PHC pile tubes are primarily adapted for use in and vertically held by applying prestressing force formation prestressed concrete member to pile body reinforcing bar
Carry.PHC pile tubes anti-bending bearing capacity is not enough, aobvious fragility, cracking resistance are poor, therefore cannot be used for side slope, foundation ditch etc. and bear horizontal lotus
The situation of load and underconsolidated soil, then adds a number of nonprestressed reinforcement in prestressed concrete pipe pile, forms new
Type hybrid reinforcement pile for prestressed pipe (abbreviation PRC).Compared with PHC, PRC horizontal bearing capacities increase, deformation performance
Improved.
But above-mentioned prefabricated tubular pile is still undesirable for structure its resistance to plucking effect required with resistance to plucking.Traditional prefabricated tubular pile resists
Pull out and mainly realized by side friction between pile body and soil, the property of soil around pile directly affects pile body frictional resistance, soil around pile it is strong
Degree is higher, and pile side friction is bigger, accordingly, for such as mud, cumulosol and strand, lakes and marhshes, valley floor, river shoal warp
Deng weak soil intensity it is relatively low in the case of, pile side friction is then smaller even without this is phase for the structure required with resistance to plucking
When unfavorable.
The general single stake stake of prefabricated tubular pile is long not enough, it is necessary to carry out pile extension, and traditional pile extension method connects for tubular pile hoop formula
Connect, first segment stake is pressed into soil by work progress after being positioned for stake position setting-out, pile foundation using static pressure method, is then hung second section and is adopted
With the mode pile extension of welding plus mechanical connecting clamp between end plate.
Utility model content
It is low in order to improve current bridge pile foundation prefabricated tubular pile side friction, the problems such as extraction-resistant behavior difference and pile extension difficult,
The utility model provides a kind of pile with fluting and using the high frictional resistance prefabricated tubular pile of reinforcing bar outside weld pile extension, in PRC prestressed pipes
The pile body increase pile with fluting symmetrically and evenly of stake simultaneously uses welded reinforcement uniformly to be welded with the steel hoop of a determining deviation and two piles
Connect, connect two piles.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of pile with fluting and the high frictional resistance prefabricated tubular pile for using reinforcing bar outside weld pile extension, it is characterised in that：Prefabricated tubular pile (1)
Circumference arm on offer on pile body notch (2), pile body notch (2) same circumference at least provided with two, on same circumference
Spacing between pile body notch (2) is identical, and pile body notch (2) is arranged at an equal pitch along pile body；Need to dock two sections are prefabricated
The end of pile tube (1) is cased with steel hoop (3) respectively, and the two ends of reinforcing bar (4) are respectively welded at the outside of steel hoop (3), pass through steel
Muscle (4) realizes the docking to two sections of prefabricated tubular piles (1).
Prefabricated tubular pile (1) is PRC prefabricated tubular piles, and its pile body surrounding is provided with notch (2).
The welded reinforcement (4) makes two sections with a determining deviation and steel hoop (3) uniform welding of two sections of prefabricated tubular piles (1)
Prefabricated tubular pile (1) is docked.
The pile body notch (2), at least provided with two, is arranged at an equal pitch on same circumference along pile body.
The pile body notch (2) is the groove with chamfering.
The beneficial effects of the utility model are：
1st, the high frictional resistance prefabricated tubular pile of a kind of pile with fluting of the utility model and use reinforcing bar outside weld pile extension, pile with fluting,
Increase stake and the contact area of soil, the build-in for making pile body stronger with soil, the side friction increase of stake improves the resistance to plucking effect of stake
Really.
2nd, the high frictional resistance prefabricated tubular pile of a kind of pile with fluting of the utility model and use reinforcing bar outside weld pile extension, is prefabricated pipe
Stake, without cast in situs, environmental protection and construction is quick, while notch prefabrication can be standardized and mass.
3rd, the high frictional resistance prefabricated tubular pile of a kind of pile with fluting of the utility model and use reinforcing bar outside weld pile extension, is enclosed using reinforcing bar
Stake is welded, the length of a pile sinking is reduced, stake processed can be separated, reduction reduces difficulty of construction, increase to hanging device requirement
The precision of pile foundation positioning.
