Abstract
The utility model discloses a fast connection device of a prestressed concrete pipe pile, comprising a lower end head and an upper end head of the pipe pile which are adjacent. A plurality of arc-shaped bolts connecting the upper and the lower end heads are disposed at a position where the lower and the upper end heads are connected. The upper and the lower end heads are connected through the arrangement of the arc-shaped bolt, thereby the mode of traditional welding pile splicing is replaced by the mode of bolt connection. An arc-shaped bolt hole for installing the arc-shaped bolt can be reserved when the pipe pile is prefabricated without adding an additional complicated process. The utility model has advantages of possessing simple structure, low processing cost, and fast and stable pile splicing; shortening construction period; having wide application in the process of prestressed concrete pipe pile splicing.
Description
Technical field
The utility model relates to a kind of piecing devices of prestressed concrete pipe pile.
Background technology
Prestressed concrete pipe pile now is extensive use of in civil construction project, and that generally uses at present has static pressure pipe pile and a hammering pile tube.In the prestressed concrete pipe pile construction process, pile extension technology mainly adopts traditional welding procedure, but this pile extension speed is slow, has influenced the integral construction speed of stake, and welding quality is difficult to guarantee that the anticorrosion endurance issues also is difficult to solve.Can't satisfy the requirement of this rapid construction worker of major diameter drilling follow pile tube method, spin out the duration.
The utility model content
The purpose of this utility model is for a kind of quick coupling device that need not to adopt the prestressed concrete pipe pile that welding procedure can firmly connect two pile tubes is provided.
The solution that the utility model solves its technical problem is:
A kind of quick coupling device of prestressed concrete pipe pile comprises the lower end and the upper end of two adjacent pile tubes, and the position that described lower end and upper end join is provided with several with the two arc bolt that links up.
As further improvement in the technical proposal, respectively be provided with several arc bolts hole in correspondence with each other on described lower end and the upper end, described arc bolt is positioned at the arc bolt hole.
As further improvement in the technical proposal, with the central axis of described pile tube be in, the arc opening of described arc bolt hole outwardly, and the arc trend is parallel with described central axis.
As further improvement in the technical proposal, described arc bolt hole is that the center is symmetrically distributed with described central axis.
As further improvement in the technical proposal, the described arc bolt hole outside is provided with plastic pipe.
As further improvement in the technical proposal, the two ends of described arc bolt hole are provided with the pile body frustum groove that is embedded on lower end and the upper end.
As further improvement in the technical proposal, the connecting port position of described pile body frustum groove and arc bolt hole is provided with the pad scrobicular ring of diameter greater than the aperture of arc bolt hole.
The beneficial effects of the utility model are: the utility model is provided with the arc bolt by the assembly at lower end and upper end by the position the two is linked up, thereby has substituted the mode of traditional welding pile extension with the mode of Bolt Connection.The arc bolt hole that will process for the arc bolt is installed can be reserved in prefabricated tubular pile, need not to increase extra complicated technology.The utility model is simple and reliable for structure, low processing cost, and pile extension is firm fast, has shortened the construction period, is widely used in the prestressed concrete pipe pile pile extension operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is axial complete section figure of the present utility model;
Fig. 2 is the A-A vertical view among Fig. 1;
Fig. 3 is the pile body frustum groove elevation in the utility model.
The specific embodiment
With reference to Fig. 1, a kind of quick coupling device of prestressed concrete pipe pile comprises the lower end 1 and the upper end 2 of two adjacent pile tubes, and described lower end 1 is provided with several with the two arc bolt 3 that links up with the position that upper end 2 joins.
Be further used as preferred embodiment, respectively be provided with several arc bolts hole 4 in correspondence with each other on described lower end 1 and the upper end 2, described arc bolt 3 is positioned at arc bolt hole 4.Described arc bolt hole 4 can promptly be made when making prestressed concrete pipe pile synchronously, by mode headspaces such as pipe layings.
Be further used as preferred embodiment, with the central axis of described pile tube be in, the arc opening of described arc bolt hole 4 outwardly, and the arc trend is parallel with described central axis.
See figures.1.and.2, be further used as preferred embodiment, described arc bolt hole 4 is that the center is symmetrically distributed with described central axis.Concrete, described arc bolt hole 4 can stay 4～8.
Be further used as preferred embodiment, described arc bolt hole 4 outsides are provided with plastic pipe 5.Described plastic pipe 5 is used for determining the position and the shape of arc bolt hole 4.
With reference to Fig. 3, be further used as preferred embodiment, the two ends of described arc bolt hole 4 are provided with the pile body frustum groove 6 that is embedded on lower end 1 and the upper end 2.
Be further used as preferred embodiment, described pile body frustum groove 6 is provided with the pad scrobicular ring 7 of diameter greater than the aperture of arc bolt hole 4 with the connecting port position of arc bolt hole 4.Described pad scrobicular ring 7 is used to place bolt pad 8, prevents that nut 9 from getting loose and wear and tear.
Be a kind of embodiment of the utility model in practical operation below:
(a) when making prestressed concrete pipe pile, near lower end 1 and upper end 2 both pile bodies, reserve some arc bolts hole 4, can determine the position and the shape of arc bolt hole 4 by pre-buried plastic pipe 5.
(b) after in the stratum, being pressed into, squeezing into or implanting the first segment prestressed concrete pipe pile, sling second the joint prestressed concrete pipe pile, and carry out centering (promptly allowing lower end 1 aim at upper end 2) with first segment prestressed concrete pipe pile corresponding position, in the pad scrobicular ring 7 in arc bolt hole 4 apertures, place bolt pad 8 then, arc bolt 3 is inserted in the arc bolt hole 4, again nut 9 is connected with arc bolt 3.In nut 9 and arc bolt 3 rundown process, should will need each arc bolt 3 of connection and nut 9 evenly afterburning on the termination up and down, tighten other nut 9 and arc bolt 3 more one by one after forbidding certain nut 9 and arc bolt 3 once tightened, be to cause stress too concentrated because of the changing of the relative positions like this in order to prevent, not only influence neutrality, also allow bolt fracture easily.The N joint is same as above with the connecting mode of N+1 joint.
More than be that better embodiment of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
