The precast pile pile hanging method
Technical field
The present invention relates to a kind of construction of prefabricated piles method, especially relate to a kind of precast pile pile hanging method.
Background technology
Traditional construction of prefabricated piles method mainly contains static pressure method and hammering method, but these two kinds of methods produce damage to pile body on the one hand, can produce soil compaction effect on the other hand, impact stake self construction quality and ambient environment.For addressing these problems, engineering circles has been developed the flush type construction method of replanting by holing in advance into precast pile.Wherein, pile body need to be sling when implanting precast pile.
In existing pile hanging method, use mechanical arm or the gripper precast pile of slinging, can be to the pile body injury of precast pile, and after the welding of precast pile pile body or connecting the steel member, then by the lifting steel member precast pile of slinging, also can be to the pile body injury of precast pile, and operation is more loaded down with trivial details.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of process of hanging to the pile body zero damage, and simple and easy to do precast pile pile hanging method.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of precast pile pile hanging method, and concrete steps are: a, choose many steel ropes, the two ends of described steel rope are the becket bridle of sealing; B, steel rope that step a is chosen wherein one along the precast pile pile body after two circles, the becket bridle of this steel rope one end is passed from the eye of the becket bridle of the other end; C, remaining steel rope is wound around the precast pile pile body with the method for step b, and the becket bridle that all pass is suspended on suspension hook; D, slow lifting hook are until all steel ropes locking precast pile; E, continuation lifting hook are sling precast pile.
Compared with prior art, the invention has the advantages that: this method wirerope-winding precast pile pile body, with the slow hoisting cable of suspension hook, after steel rope locking precast pile pile body, continuing lifting hook slings precast pile, whole work progress is simple and easy to do, and due to the elasticity of steel rope, can be to precast pile pile body injury.
As preferably, described steel rope is 2, and is symmetrical with the precast pile axis after described steel rope locking precast pile pile body, and two steel ropes exceed the equal in length of precast pile pile body part.The precast pile pile body is stressed steadily, is difficult for when slinging rocking.
As preferably, described steel rope is 3, after described steel rope locking precast pile, evenly distributes centered by the precast pile axis.The precast pile pile body is stressed more steady, and still can hang precast pile after the unexpected fracture of steel cable therein.
As preferably, the length of annulus is 20 centimetres~50 centimetres.According to the size of wirerope diameter, suitable annulus is set, can causes steel rope to be difficult to lock the precast pile pile body when annulus is excessive.
As preferably, the length of described steel rope is 200 centimetres~600 centimetres.Select suitable steel rope according to precast pile pile body size and length, and during the steel rope of selection different length, can prevent from disturbing between steel rope.

The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
The concrete steps of this precast pile pile hanging method are: a, choose many steel ropes 1, the two ends of steel rope 1 are the becket bridle 11 of sealing; B, steel rope 1 that step a is chosen wherein one along precast pile 2 pile bodies apart from 1/5 place, top after two circles, the becket bridle 11 of these steel rope 1 one ends is passed from the eye of the becket bridle 11 of the other end; C, with remaining steel rope with the method for step b be wound around the precast pile pile body should the place near, and all becket bridles that pass 11 are suspended on suspension hook; D, slow lifting hook are until all steel rope 1 locking precast piles 2; E, continuation lifting hook are sling precast pile 2.Whole work progress is simple and easy to do.Wherein, when slow lifting hook, due to the weight effect of precast pile, all steel ropes 1 can progressively be revised, and make all steel ropes 1 all lock precast pile 2.
Wherein, steel rope 1 is preferably 2~5.When steel rope is 2, can be in the slow lifting hook process of steps d suspension hook, adjust the steel rope position, symmetrical with the precast pile axis after making 2 steel ropes locking precast pile pile bodies, and two steel ropes exceed the equal in length of precast pile pile body part.When steel rope is 3, can be in the slow lifting hook process of steps d suspension hook, adjustment steel rope position, after making 3 steel rope locking precast piles, evenly distribute centered by the precast pile axis, the precast pile pile body is stressed more steady, and still can hang precast pile after the unexpected fracture of steel cable therein.
Select the thickness of steel rope 1 according to the weight of precast pile 2, the diameter of steel rope 1 is generally 5 millimeters~30 millimeters.The length of annulus 11 is generally 20 centimetres~50 centimetres according to the size setting of steel rope 1 diameter.The length of steel rope 1 is selected according to precast pile 2 pile body sizes and length, and length generally is generally 200 centimetres~600 centimetres.
This method adopts steel rope 1 as twister, is to consider that steel rope 1 has good elasticity, can be to precast pile pile body injury.
