Abstract
The invention provides a kind of multiple-top vibrator for sand lining pile, formed by two or more vibrating heads (1).The wing plate (11) of each vibrating head (1) weldering is inserted in the opening (12) of bottom inner sleeve (2) tube wall.The top of each vibrating head (1) is top inner sleeve (3) by the inboard that dowel bar and pillar (5) thereof connect motor (7), dowel bar and pillar (5) thereof, and the bottom that its outside is outer tube (6), outer tube (6) is to irritate the flap valve (4) that sand is used.Vibrating head (1) produces needed horizontal vibration power, and has enough spaces to place bigger reinforcing cage between the vibrating head (1).Working as ultimate bearing capacity according to test is that 4.11 ton hours adopt the present invention to save concrete 65% than common filling pile.
Description
The invention belongs to foundation pile construction equipment.
No. 85104918 patents of CN provide the construction special equipment of a kind of concrete tamper stake, and it can once be finished two operations of moulding of the perfusion of tamper and concrete core, its techno-economic effect is tangible.But its used diameter of inner pipe is subjected to the restriction of submersible motor structure.Can't be too big.And diameter of inner pipe has limited the reinforcing cage diameter of stake.Like this, reinforcing cage just is too near to the center of stake.When eccentric load, influenced the performance of reinforced steel bar strength.Obviously, this is an improved problem of needs.
Purpose of the present invention just is to provide a kind of multiple-top vibrator for sand lining pile.This how excellent vibrator bottom is made up of two or more vibrating head, and the wing plate that welds on each vibrating head is inserted in the opening of bottom inner pipe wall.Vibrating head produces needed horizontal vibration power, and has enough spaces to place bigger reinforcing cage between the vibrating head.
The technical scheme of above-mentioned task illustrates as embodiment in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 now.
Fig. 1 is the structural representation of how excellent vibrator;
Fig. 2 is II-II sectional drawing of Fig. 1;
Fig. 3 is I-I sectional drawing of Fig. 1;
Fig. 4 is III-III sectional drawing of Fig. 1.
Vibrating head among Fig. 2 (1) is 5.In fact vibrating head (1) can be more than 2 or 2.The quantity of vibrating head (1) is determined by the diameter of tamper stake and the diameter of vibrating head (1).Vibrating head (1) can be the concrete vibration bar of 50 millimeters of existing φ or 70 millimeters of φ or other specification on the market.
Be welded with two wing plates (11), wide 20 millimeters on the side of vibrating head (1) symmetrically, thick 5 millimeters, length is identical with vibrating head; Disconnect at the position that vibrating head need be dismantled.The wing plate (11) of vibrating head (1) is inserted in the opening (12) that hoop distributes on bottom inner sleeve (2) tube wall, the both sides of opening (12) are made up of relative vertical notch (13), vertical notch (13) is wide 9 millimeters, dark 20 millimeters, two cell walls are wide 20 millimeters, thick 5 millimeters, length is identical with wing plate (11).
Opening (12) lower end that hoop distributes on the tube wall of bottom inner sleeve (2) and the bottom of inner sleeve (2) be not in same level, and its distance requires decision by the bulk strength of how excellent vibrator construction.The bottom of bottom inner sleeve (2) is a complete steel pipe.There is not opening, as shown in Figure 3.The upper end of each vibrating head (1) is connected with dowel bar and pillar (5) thereof.The upper end of dowel bar and pillar thereof (5) is connected with motor (7), and its quantity is identical with vibrating head (1).
Fig. 4 is III-III sectional drawing of Fig. 1.As seen from Figure 4, dowel bar and pillar thereof (5) nestle up top inner sleeve (3), and its outside is outer tube (6).Connect by junction plate (10) between top inner sleeve (3) and the outer tube (6).Concrete in top in pipe box (3) and the bottom inner sleeve (2), sand then flow through flap valve (4) via the annular canister between outer tube (6) and the top inner sleeve (3) and time be sunken to the concrete pile core around.
Two vertical vibrators (8) are installed in the outside, upper end of top inner sleeve (3) symmetrically.Top inner sleeve (3) top is provided with suspension ring, is suspended on the outside pile frame by lifting rope (9).
Multiple-top vibrator for sand lining pile is usually used in the soft foundation construction.As when hard soil foundation is constructed, can be earlier with common auger boring, then with the stake of how excellent vibrator construction tamper.For in the hard soil foundation easy construction, also can temporarily remove two vertical vibrators (8) of how excellent vibrator and outer tube (6).
The present invention has done the tamper stake test of 300 millimeters of φ in the boring on hard soil foundation.Stake is long 1800 millimeters, and 219 millimeters of bottom inner sleeve φ, top inner sleeve are 108 millimeters of φ.Result of the test shows: when the ultimate bearing capacity of stake is 4.11 ton hours.Tamper stake with pile of the present invention is saved concrete 65% than the cast-in-place concrete pile of same ultimate bearing energy, saves cost 55%.
Claims (2)
1, a kind of tamper stake vibrator comprises two or more vibrating heads (1).It is characterized in that these vibrating heads (1) are linked up by bottom inner sleeve (2), the top of each vibrating head (1) connects motor (7) by dowel bar and pillar (5) thereof, the inboard of dowel bar and pillar thereof (5) is the top inner sleeve (3) of vibrator, its outside then is outer tube (6), between outer tube (6) and the top inner sleeve (3) junction plate (10) is arranged, the bottom of outer tube (6) is flap valve (4).
2, connecting according to the described vibrating head of claim 1 (1) and bottom inner sleeve (2), it is characterized in that on vibrating head (1), being welded with wing plate (11), be inserted in the opening (12) that hoop distributes on bottom inner sleeve (2) tube wall, the both sides of opening (12) are made up of relative vertical notch (13).
