Basis for there being specified level bearing capacity to need selects to provide a kind of new pile-type.
Brief description
Fig. 1 is longitudinal semi-cutaway of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Fig. 3 is end view drawing of the present utility model.
Detailed description of the invention
Describe preferred embodiment of the present utility model below in conjunction with accompanying drawing in detail, but, the utility model is not limited to
Detail in above-mentioned embodiment, in technology concept of the present utility model, can be to skill of the present utility model
Art scheme carries out multiple equivalents, and these equivalents belong to protection domain of the present utility model.
This embodiment is partially prestressed concrete pile tube, and it mainly includes the 3rd deformed bar 301, and prism of third order body mixes
Solidifying soil 302, the 3rd tubular steel grid 303, the 3rd non-prestressing tendon 304, the 3rd steel hoop 305, the 3rd end plate
306 and the 3rd steel hoop indenture 307.
In this embodiment, pile concrete selects C60～C80.Pile concrete by the consumption requirement of every centrifugal pile tube,
Use charge car that fresh concrete uniformly fills up female die along mould, many as far as possible some concrete of cloth in stretch-draw one end.
Pile concrete wall thickness takes 80～130mm.Grid in tubular bar-mat reinforcement is rhombus.Tubular bar-mat reinforcement is away from stake end three
Increase mesh-density, to reach cipher round results in times stake footpath is interval.The steel grid of tubular bar-mat reinforcement resists according to required bending resistance
Cutting the difference of bearing capacity, steel grid angulation is also different, in the range from 30 °～150 °.Tubular bar-mat reinforcement
Network length of side span is at 50mm～400mm.The reinforced steel bar strength used of tubular bar-mat reinforcement resists according to required bending resistance
Cut the difference of bearing capacity, can be selected for the round reinforcing bar of hot calendering or employing first class cold-drawn low-carbon wire.Steel used by tubular bar-mat reinforcement
Muscle diameter is otherwise varied according to selected bar types difference, the round bar diameter of hot calendering between choose 6～10mm,
And first class cold-drawn low-carbon wire diameter is at 4～8mm.Nonprestressed reinforcement is different from ductility according to required bending strength,
Arrange a non-prestressing tendon between every deformed bar, it is possible to often between several deformed bars, arrange a non-pre-
Stress reinforcing bar.The reinforced steel bar strength of nonprestressed reinforcement according to the difference of required bending strength, its reinforcing bar can for HPB300,
HRB335, HRB400 and HRB500.The diameter of nonprestressed reinforcement is unsuitable with deformed bar different diameters excessive.
It is the diameter thin-wall circular steel pipe equal with pile tube external diameter that pile tube two ends are equipped with steel hoop, and end plate is identical with pile tube cross section
Circular hollow steel plate, end plate is welded on steel hoop one rear flank and is arranged on an end.It is welded with inside end plate with non-prestressing tendon with rule
Lattice, the anchor rib of equivalent amount, welding distributed points is basically identical with pile body non-prestressing tendon position.Non-prestressing tendon and anchor
Gu the mode using colligation overlap joint between reinforcing bar connects, the mode that anchor rib uses weld all around or stopple to weld with end plate is connected.Steel
Cuff is provided with two indentures on surface.Indenture is arranged at steel hoop, along the lateral arrangement two of steel hoop.
In this embodiment, longitudinal prestressing reinforcing bar and the non-pre-of the partially prestressed concrete pile tube of grid form of reinforcement should
Power muscle is wrapped up by tubular steel grid, and integrated tubular steel grid is increasing mesh-density cloth in three times of stake footpaths of stake end are interval
Put, and suitably adjust network angle and the length of side according to actual needs.The prestressed concrete pipe pile of grid form of reinforcement
Two ends are equipped with the diameter thin-wall circular steel pipe cuff equal with pile tube external diameter, and end plate mixes for the prestressing force with grid form of reinforcement
The identical circular hollow steel plate in solidifying soil pile tube cross section, end plate is welded on steel hoop one rear flank and is arranged on an end, adds inside end plate
Weldering and non-prestressing tendon same specification, the anchor rib of equivalent amount, welding distributed points and pile body non-prestressing tendon position basic
Cause.The mode using colligation overlap joint between non-prestressing tendon with anchor bar is connected, and anchor rib uses weld all around or hole with end plate
The mode of plug welding connects.
In a word, the utility model engineering structure antidetonation pile tube, especially its built-in stirrup are grid form of reinforcement, outside mixed
Solidifying soil is high-strength concrete.Vertical bearing capacity is good, and when by horizontal loading, netted form of reinforcement is compared to general
The generation of pile body diagonal crack and the inhibitory action of development are become apparent from by logical tie hoop, and its bending resistance shear-carrying capacity is compared
Having bigger lifting in prestressed concrete pipe pile, nonprestressed reinforcement can improve the ductility of pile tube itself simultaneously, compensate for
The general hypodynamic shortcoming of prestressed concrete pipe pile lateral loading.
