The middle part of described reinforcing bar II and one end of connecting rod II hinged; Described connecting rod II other end is evenly hinged on annulus II; Described annulus II slip cap to be contained on concrete pipe and to be positioned at below annulus I;
Described wire rope group I one end is connected to connecting rod I; Described wire rope group II one end is connected on connecting rod II; Described steel strand I have many, and it is connected with reinforcing bar I colligation; Described steel strand II have many, and it is connected with reinforcing bar II colligation; When upwards pulling wire rope group I and wire rope group II, annulus I and annulus II are along concrete pipe outer wall upward sliding, and when reinforcing bar I and reinforcing bar II outwards strut and reach assigned position by connecting rod I and connecting rod II, steel strand I and steel strand II are in complete tensioning state.
It is further: between described reinforcing bar II and reinforcing bar III, be connected with steel strand III; Steel strand IV are connected with between described reinforcing bar I and reinforcing bar III; When upwards pulling wire rope group I and wire rope group II, annulus I and annulus II are along concrete pipe outer wall upward sliding, when reinforcing bar I and reinforcing bar II outwards strut and reach assigned position by connecting rod I and connecting rod II, steel strand I and steel strand II are in complete tensioning state, and steel strand III and steel strand IV are in the state that is straightened completely simultaneously.
The invention has the beneficial effects as follows:
1, after filling concrete, its pile becomes Pear-Shaped, increases steadiness and the intensity of pile.
2, the reaming part of hole-expanding pile has reinforced bar support, after concrete setting, improves the reliability of stake.
3, the present invention may reduce quantity and the diameter of existing stake, thus can reduce construction cost, reduction of erection time.
4, the present invention build there is broken pile time, still reinforcing cage can be taken out, avoid unnecessary waste.

Detailed description of the invention
Be below a specific embodiment of the present invention, existing the invention will be further described by reference to the accompanying drawings.
As shown in Figures 1 to 4, a kind of skirt-type opened reinforcing cage of hole-expanding pile, it comprises stirrup II 10, reinforcing bar III 7, concrete pipe 8; Stirrup II 10 is evenly arranged in around concrete pipe 8, and each stirrup II 10 is fixedly connected with by reinforcing bar III 7; Device also comprises stirrup I 1, reinforcing bar I 2, reinforcing bar II 5, connecting rod I 4, connecting rod II 12, annulus I 9, annulus II 14, wire rope group I 11, wire rope group II 13, steel strand I 3 and steel strand II 6; Stirrup I 1 horizontal arrangement, its inner ring is connected with reinforcing bar III 7 colligation formed a circle; Reinforcing bar I 2 is multiple altogether, and its one end is evenly hinged on stirrup I 1, and one end of the other end and reinforcing bar II 5 is hinged; Middle part and connecting rod I 4 one end of reinforcing bar I 2 are hinged; Connecting rod I 4 other end is evenly hinged on annulus I 9; Annulus I 9 slip cap is contained on concrete pipe 8; The middle part of reinforcing bar II 5 and one end of connecting rod II 12 hinged; Connecting rod II 12 other end is evenly hinged on annulus II 14; Annulus II 14 slip cap to be contained on concrete pipe 8 and to be positioned at below annulus I 9; Wire rope group I 11 one end is connected to connecting rod I 4; Wire rope group II 13 one end is connected on connecting rod II 12; Steel strand I 3 have many, and it is connected with reinforcing bar I 2 colligation; Steel strand II 6 have many, and it is connected with reinforcing bar II 5 colligation; Steel strand III 15 are connected between reinforcing bar II 5 and reinforcing bar III 7; Steel strand IV 16 are connected between reinforcing bar I 2 and reinforcing bar III 7; When upwards pulling wire rope group I 11 and wire rope group II 13, annulus I 9 and annulus II 14 are along concrete pipe 8 outer wall upward sliding, when reinforcing bar I 2 and reinforcing bar II 5 outwards strut and reach assigned position by connecting rod I 4 and connecting rod II 12, steel strand I 3 and steel strand II 6 are in complete tensioning state, and steel strand III 15 and steel strand IV 16 are in the state that is straightened completely simultaneously.
The course of work is:
1, by the state that the present invention does not open by Fig. 4, annulus I 9 and annulus II 14 are enclosed within concrete pipe 8, put into the boring that reaming is complete.
2, pull-up wire rope group I 11 and wire rope group II 13, move extreme position to, and now the present invention is as the state of Fig. 2, and steel strand I 3, steel strand II 6, steel strand III 15, steel strand IV 16 are all tightened up.
3, under steel strand I 3, steel strand II 6, steel strand III 15, steel strand IV 16 are all tightened up state, by concrete pipe concreting, for ensureing pouring quality, during concreting, the position that concrete pipe end opening is enough dark inside concrete all the time, avoids broken pile.In casting process, concrete pipe is constantly promoted, and when concrete pipe departs from annulus I 9 and annulus II 14, can open in skirt-type reinforcing cage and be full of concrete, become concrete reinforcement component.Now continue tense wire rope group I 11 and wire rope group II 13, keep the tensioning degree of reinforcement component, until build end, wire rope group I 11 and wire rope group II 13 are also cast in concrete.
