Abstract
The invention discloses a construction method for a rammed and reamed pre-stressed hollow pipe pile. The construction method comprises the following steps: arranging a PVC (Polyvinyl Chloride) protective pipe in a pile hole of a hollow pile; filling dry concrete into the PVC protective pipe and hammering the dry concrete by using a long-column hammer to form a soil and water obstructing pile plug; subsequently filling C30 dry concrete into the PVC protective pipe; hammering the soil and water obstructing pile plug and the C30 dry concrete by using the long-column hammer in order to form a rammed and reamed body, and forming the hollow pipe pile disclosed by the invention by using the rammed and reamed body and the hollow pile. The construction method disclosed by the invention is quick in construction; the pile body is good in quality; the pile hole of the hollow pile is used as a ramming and reaming outer pipe, and an expanded head is formed at the pile end, so the bearing capacity of a single pile is greatly increased.
Description
Technical field:
The present invention relates to a kind of construction method rammed and expand pre stressed empty piped piles.
Background technology:
Existing prestressing pipe pile construction uses static pressure method or hammering method that lower end has pile top hollow shell pill be driven in design soil layer.Hollow shell pill speed of application is fast, and pile quality is good.But stake end area is less, and bearing capacity of pile tip is the highest.
Existing rammed bulb pile typically uses first pore-forming, rammed bulb pile end, in situ concrete pile, and speed of application is slow, and pile quality is wayward.
Summary of the invention:
The present invention provides the construction method ramming expansion pre stressed empty piped piles that a kind of pile driving construction speed is fast, pile quality good, bearing capacity is high.
The technical solution adopted in the present invention has: a kind of construction method ramming expansion pre stressed empty piped piles, including:
1) Prefabricated hollow pile: concrete and steel reinforcement cage pour formation hollow pile；
2) hollow pile squeezes into soil layer: put pile top on soil layer to be onstructed, is placed in this pile top by described hollow pile, rams hollow pile, hollow pile and pile top is squeezed in described soil layer；
3) protection pipe is put into: protection pipe is put into the stake holes of hollow pile；
4) pile top departs from hollow pile: long column weight is put into protection pipe, hammering pile top repeatedly so that pile top departs from hollow pile；
5) resistance earth, water stake plug are formed: in protection pipe, irrigate dryness concrete, by this dryness concrete of long column weight hammering repeatedly and at the formation of the bottom of hollow pile resistance earth, water stake plug；
6) rammer expansion hollow shell pill is formed: repeatedly perfusion is more than C30 dryness concrete in protection pipe, and with concrete described in the hammering repeatedly of long column weight, formation rammer expands body, and described rammer expands body and forms described rammer expansion hollow shell pill with hollow pile.
Further, described steel reinforcement cage includes that main muscle and stirrup, some main ribs surround a columned cage body, and described stirrup is circumferentially positioned in this cage body.
Further, the diameter of described hollow pile is not less than 500mm.
Further, the diameter of described protection pipe is less than the diameter 50-80mm of hollow pile.
Further, described protection pipe uses PVC material to make.
There is advantages that
The present invention puts into PVC protection pipe in the stake holes of hollow pile; and protect pipe pour into dryness concrete and pass through this dryness concrete of long column weight hammering and form resistance earth, water stake plug to this PVC; C30 dryness concrete is poured into again to PVC protection pipe; again by long column weight hammering resistance earth, water stake plug and C30 dryness concrete; formed to ram and expand body; consequent provide the benefit that: speed of application of the present invention is fast; pile quality; the stake holes utilizing hollow pile expands outer tube as ramming; form enlarged footing at stake end, substantially increase the bearing capacity of single pile.
Accompanying drawing illustrates:
Fig. 1 is that soil layer construction figure is squeezed in construction method hollow core stake of the present invention.
Fig. 2 is to put into protection tubular construction figure in construction method of the present invention in hollow pile.
Fig. 3 is the structure chart that in construction method of the present invention, pile top departs from hollow pile.
Fig. 4 is to form resistance earth, the structure chart of water stake plug in construction method of the present invention.
Fig. 5 is to be formed in construction method of the present invention to ram the structure chart expanding hollow shell pill.
Fig. 6 is the reinforcement cage structure figure in hollow core pile tube of the present invention.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1 to Fig. 5, the present invention is a kind of rams the construction method expanding pre stressed empty piped piles, and its construction procedure is as follows:
1) Prefabricated hollow pile, concrete and steel reinforcement cage pour formation hollow pile 1, and the diameter of this hollow pile 1 is not less than 500mm.
2) hollow pile squeezes into soil layer, puts pile top 2 on soil layer to be onstructed, is placed in pile top 2 by above-mentioned hollow pile 1, rams hollow pile 1 by piling machine, hollow pile 1 and pile top 2 is squeezed in soil layer.During piling machine hammering hollow pile 1 enters soil layer, pile top 2 contributes to hollow pile 1 and enters soil layer, and can effectively prevent earth from entering in the stake holes of hollow pile 1, such as Fig. 1.
3) putting into protection pipe, put into protection pipe 3 in the stake holes of hollow pile 1, this protection pipe uses PVC material to make, and diameter is less than the diameter 50-80mm of hollow pile, such as Fig. 2.
4) pile top departs from hollow pile, the long column weight 4 less than hollow pile 1 diameter 50-80mm is put into the tube chamber of protection pipe 3, hammering pile top repeatedly 2 so that pile top 2 departs from hollow pile 1, such as Fig. 3.
5) resistance earth, water stake plug are formed; being proposed by long column weight 4, in the tube chamber of protection pipe 3, influx height is the dryness concrete of 100mm, by this dryness concrete of long column weight 4 hammering repeatedly; this dryness concrete is made to form resistance earth, water stake plug 5 in the bottom of hollow pile 1, such as Fig. 4.
6) form rammer and expand hollow shell pill; repeatedly in protection pipe, perfusion is more than C30 dryness concrete; with this dryness concrete of long column weight 4 hammering repeatedly and resistance earth, water stake plug 5; and make C30 dryness concrete and resistance earth, water stake plug 5 form rammer expansion body 6 in the bottom of hollow pile 1; this rammer expands body 6 and rams expansion hollow shell pill, such as Fig. 5 with the hollow pile formation present invention.
Such as Fig. 6, the steel reinforcement cage 10 in hollow pile 1 includes that main muscle 11 and stirrup 12, some main muscle 11 surround a columned cage body, and stirrup 12 is circumferentially positioned on the inside and outside circle cylinder of this cage body.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
