Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-3, a kind of directional expansion pipe 4 for dustless directional fracture foundation pile pile crown, comprise outer expansion tube 42, the lower end lower end cap 41 of described outer expansion tube 42 seals, prevent the expansion agent in outer expansion tube 42 from flowing out, described outer expansion tube 42 inside is also provided with interior expansion tube 44, and between outer expansion tube 41 and interior expansion tube 44, be provided with the spring 43 being in compressive state, described spring 43 lower end contacts with lower end cap 41, upper end is connected with interior expansion tube 44 lower end, the upper end upper plug head 45 of interior expansion tube 44 seals, and upper plug head 45 connecting stay wire 46 one end, described bracing wire 46 other end is connected with the cross bar 49 being arranged on upper plug head 45 outside, the balanced line 48 for balancing spring 43 elastic force is also provided with between described cross bar 49 and lower end cap 41, described balanced line 48 is connected with cross bar 49 by the metal hook of end.The tube wall of described outer expansion tube 42 and interior expansion tube 44 is equipped with some axial notches 47, for reducing pipeline strength, is convenient to pipeline and is inflated agent and bursts.
Refer to Fig. 4 and Fig. 5, the Specific construction step that application the utility model carries out dustless directional fracture foundation pile pile crown comprises:
(1) on reinforcing cage 1, design the pile crown interface 3 of level;
(2) at least one directional expansion pipe 4 that the inclined upward of pile crown interface 3 is installed, and directional expansion pipe 4 is 5-15 ° with the angle of pile crown interface 3, and reinforcing cage 1 is stretched out in directional expansion pipe 4 upper end, and the central axis of reinforcing cage 1 is pointed in lower end;
(3) outside of every root vertical reinforcement 6 of the reinforcing cage 1 of pile crown interface more than 3 is set with isolated tube 5, and isolated tube 5 and vertical reinforcing bar 6 matched in clearance, isolated tube 5 upper and lower side does sealing process; Described isolated tube 5 adopts plastic pipe (pvc pipe) or metal tube or foam software, prevents the concrete of pile crown from contacting with vertical reinforcement 6, plays insulation blocking effect;
