The upper end of sounding sleeve pipe is higher than the upper end 75mm of sound detecting pipe; The lower end of sounding sleeve pipe is lower than pile crown line of cut 25mm, the length that can calculate sounding sleeve pipe is thus 1100mm, the external diameter of sound detecting pipe is 50mm, the space being not less than 5mm should be retained between the internal diameter of sound detecting pipe external diameter and sounding sleeve pipe, cut out the PE pipe 3 that the long external diameter of 1100mm is 65mm, internal diameter is 60mm.
Two security strips preventing from rising of steel cage from causing separator tube position offseting are provided with at described reinforcing cage bottom position; Described security strip is security strip be width is 50mm, thickness is the steel plate of 5mm, and two security strips become right-angled intersection to arrange, the vertical main muscle in security strip width face.
B. the length section that main muscle needs cover to become owner of tendon bush is the length of lower end to main muscle top of main tendon bush, thus void filler is set at the length section of main muscle downward 1025mm from top, void filler is foamed glue and plastic foil, described plastic foil is wrapped on main muscle external diameter, blend compounds band is fixed on main muscle, at plastic foil trypsin method foamed glue.
Sound detecting pipe needs the length section being inserted in sounding sleeve pipe to be the length of lower end to sound detecting pipe top of sounding sleeve pipe, void filler is put thus at the length section of sound detecting pipe downward 1025mm from top, void filler is foamed glue and plastic foil, described plastic foil is wrapped on sound detecting pipe external diameter, blend compounds band is fixed in sounding, at plastic foil trypsin method foamed glue.
C. the main tendon bush cut by step a is inserted in the main muscle being provided with void filler by step b, be enclosed within the lower end of the main tendon bush on main muscle lower than pile crown line of cut 25mm, sealant tape is wound around in the lower end of main tendon bush, sealant tape cover main tendon bush length L4=50mm, cover the length L5=50mm(of main muscle as shown in Figure 5), be wound around the number of turns and be not less than 5 circles, sealant tape makes the gap between main tendon bush and main muscle be sealed and makes main tendon bush be fixed on main muscle; The sounding sleeve pipe cut by step a is inserted in the sound detecting pipe being provided with void filler by step b, be enclosed within the position of lower end lower than 25mm below pile crown line of cut of the sounding sleeve pipe on sound detecting pipe, sealant tape is wound around in the lower end of sounding sleeve pipe, the length of sealant tape covering sounding sleeve pipe is 50mm, the length covering sounding is 50mm, be wound around the number of turns and be not less than 5 circles, the gap between sounding sleeve pipe and sound detecting pipe is sealed and sounding sleeve pipe is fixed on sound detecting pipe.To main tendon bush higher than filling-foam glue in the pipeline section of main muscle upper end; To sounding sleeve pipe higher than filling-foam glue in the pipeline section of sound detecting pipe upper end.
D. flexible outer tube and the Inner muscle of described separator tube is cut according to the length of enclosing around reinforcing cage main muscle one and described extension; Flexible outer tube is external diameter is 40mm, internal diameter is the rubber tube of 35mm, the wire rope of Inner muscle to be diameter be 20mm; The extension of flexible outer tube is 100mm, the length around main muscle one circle of reinforcing cage and extension is surveyed with flexible outer tube, the flexible outer tube Inner muscle identical with flexible outer tube with length is cut by the length of actual measurement, interior muscle is penetrated in the endoporus of flexible outer tube, in the space between flexible outer tube and interior muscle, fill fine sand, the two ends sealant tape of separator tube seals.
E. separator tube steps d made has the reinforcing cage of main tendon bush main muscle one circle at pile crown line of cut position ring around cover, and separator tube arranges the extension extended to pile foundation outer wall direction at two ends joining place; Adopt steel wire by separator tube colligation on the external diameter of main tendon bush, during colligation, first by steel wire tighten on main tendon bush, then colligation separator tube, controls the colligation dynamics of separator tube, muscle in the separator tube after by colligation is moved in flexible outer tube.
F. to pile foundation concreting, concretely build the position highly exceeding separator tube, when concreting, the two ends junction of separator tube is marked.
G. after pile foundation concrete reaches hardness requirement, excavation pile foundation makes the above position of pile crown line of cut expose, according to the mark of step f to the two ends junction of separator tube, the concrete of the two ends junction of hammering separator tube, makes the two ends junction of separator tube expose the extension of separator tube; Remove in the termination of extension the sealant tape be wound around, from separator tube, extract Inner muscle out.Continue along pile crown line of cut position hammering concrete, the concrete between separator tube and pile foundation outer wall is come off, and separator tube exposes.When extracting Inner muscle out, thickness because the intensity of Inner muscle is higher, between separator tube and pile foundation outer wall is less, makes the concrete between separator tube and pile foundation outer wall come off sometimes, whole separator tube is pulled out, therefore can, no longer along pile crown line of cut position hammering concrete, operation be simplified.
H. use hammer drill to bore 6 sorting holes around pile foundation to vertical pile body direction along the position ring of separator tube in pile foundation, the degree of depth of described sorting hole is not less than 300mm; Then will be separated chock to insert in sorting hole, pile foundation is knocked in the position along separator tube, is separated until sorting hole place pile crown produces with design pile body end face.
I. use lifting machine to hang out the top pile crown be separated with pile foundation pile body, main tendon bush and sounding sleeve pipe are together hung out with described top pile crown.Then the plastic foil of colligation on main muscle and sound detecting pipe and foamed glue (i.e. described void filler) is removed.
