" V " shape reinforcing bar 6 is equipped with away from one end of foundation pile ontology 1, the setting of " V " shape reinforcing bar 6 enhances the stability of fixed steel bars 5,
When fixed steel bars 5 loosen, " V " shape reinforcing bar 6 limits fixed steel bars 5, and fixed steel bars 5 is avoided to face away from 6 side of " V " shape reinforcing bar
To movement, it is free to be additionally provided with band away from foundation pile ontology 1 between 2 bottom of foundation pile ontology 1 and foundation pit for the point of " V " shape reinforcing bar 6
The supporting table 4 of gap, the area of 4 table top of supporting table are more than the floor space of foundation pile ontology 1, and the fixed steel bars 5 on foundation pile ontology 1 pass through
Supporting table 4, foundation pile ontology 1 contact at supporting table 4, and water has been poured in the gap between 2 bottom of 4 table top of supporting table and foundation pit
Mud has poured cement in the gap between 2 side wall of foundation pile ontology 1 and foundation pit.
Implementation process：Supporting table 4 is mounted in foundation pit 2, then foundation pile ontology 1 is placed in supporting table 4, makes foundation pile sheet
Fixed steel bars 5 and " V " shape reinforcing bar 6 on body 1 pass through the gap in supporting table 4, since the area of 4 table top of supporting table is more than foundation pile
Cement is injected into 4 table top of supporting table in the following, by pouring water by the floor space of ontology 1 by the gap around 4 table top of supporting table
Mud connects supporting table 4 and foundation pit 2, meanwhile, cement in foundation pit 2 is by the fixed steel bars 5 and " V " shape on foundation pile ontology 1
Reinforcing bar 6 is fixed, and by being fixed to fixed steel bars 5 and " V " shape reinforcing bar 6, realizes the limiting in the vertical direction to foundation pile ontology 1.
After joints cement below 4 table top of supporting table, by the gap between 2 side wall of foundation pile ontology 1 and foundation pit, by water
Mud is cast in gap, and by the joints cement in gap, foundation pile ontology 1 and foundation pit 2 are connected, foundation pile ontology 1 is made to exist
It is limited in horizontal direction.
After foundation pile ontology 1 is limited in the horizontal direction with vertical direction, precast pier 17 is placed on foundation pile ontology 1
In pier hole 3, when installing precast pier 17, the first reinforcing bar 8 is made to be inserted into the first reinforced hole 7, the second reinforcing bar 14 is inserted into second
In reinforced hole 15, precast pier 17 is limited, cement is cast between precast pier 17 and pier hole 3 by slope 16
In gap, then by the second reinforced hole 15 cement is cast in the second reinforced hole 15 through one end of precast pier 17, so as to
Second reinforced hole 15 is tightened together with the second reinforcing bar 14, due to the outer profile of the profile that gusset 9 forms and precast pier 17
Match, gusset 9 is put into one end limiting to precast pier 17 close to foundation pile ontology 1, avoids its inclination.
Embodiment 2：A kind of bridge pier foundation pile precast construction, with embodiment 1 the difference lies in, as shown in Figure 4 and Figure 5,
