Device abolished by a kind of bridge pile foundation pile crown of the utility model, effectively solves the damage problem that bridge pile foundation pile crown abolishes construction pile foundation sound detecting pipe and the main muscle of pile foundation.Avoid pile crown to abolish damage to sound detecting pipe under pneumatic pick in construction or External Force Acting, and the invalid pile crown of pile foundation disposablely can be abolished and puts in place, pile crown is abolished the main muscle of rear pile foundation and is repaired without the need to secondary adjustment.This apparatus structure is simple, and flexible operation, cost are low, economical and efficient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, device abolished by a kind of bridge pile foundation pile crown, comprises isolated location, lifting unit, and described isolated location is carved 4 by PVC sleeve pipe 1, rubber hose 2 and steel and formed; Lifting unit is made up of hoisting ring 3 and lifting rope 6.
Described PVC sleeve pipe 1 is the protective casing of the main muscle 5 of pile foundation, sound detecting pipe 8; diameter is φ 25mm or φ 55mm; many PVC sleeve pipes 1 are inserted on the main muscle 5 of many piles base, sound detecting pipe 8; coverage is the invalid pile body part 10 of pile foundation; PVC sleeve pipe 1, mainly as the main muscle 5 of pile foundation, sound detecting pipe 8 and concrete seven isolation sleeve pipe, seals after adopting adhesive tape 9 and the main muscle 5 of pile foundation, sound detecting pipe 8 to be wound around a few, fixes bottom PVC sleeve pipe 1.
Described rubber hose 2 circlewise, make a circle outside the invalid pile body part 10 bottom reinforcement bars cage (Pile Foundations Design absolute altitude H) being arranged in pile foundation, adopt thin wire and pile foundation main muscle 5 temporary fixed at interval of certain distance, in rubber hose 2 joint junction, wherein will vertically cause pile crown top outer by an end joint outside pile foundation wherein a main muscle, leak outside free segment 30cm.
Described steel is carved 4 and is carved for engineering ordinary steel, and the radius that 4 length are more than or equal to pile foundation carved by steel, and the later stage is as the cutting device between effective pile body part 11 of pile foundation and invalid pile body part 10.
Described hoisting ring 3 is plain bars processing and fabricating, and pre-buried to invalid pile body part 10 in pile foundation concrete seven is built, hoisting ring 3 is symmetrical set, and length of embedment is not less than 30cm.
Described lifting rope 6 is wire rope, and later stage and hoisting ring 3 are detained to tie and formed boom hoisting.
Implementation step:
1), pile foundation steel bar cage adds man-hour, according to design drawing pile foundation length, reinforcing cage measured design stake top mark high, and encloses on the main muscle 5 of pile foundation at reinforcing cage one and make mark; PVC sleeve pipe 1 is inserted in the main muscle 5 of the pile foundation of more than design elevation H, sound detecting pipe 8, main muscle 5, sound detecting pipe 8 seal after being wound around a few, fix with pile foundation by bottom PVC sleeve pipe 1 to adopt adhesive tape 9, do not enter in PVC sleeve pipe 1 when ensureing concreting, adhesive tape 9 stretches into 5cm in effective pile body part 11.
In reinforcing cage design elevation position, rubber hose 2 is adopted to enclose along the peripheral horizontal wrap one of reinforcing cage, and adopt thin wire interval temporary fixed, rubber hose 2 joint junction, wherein will vertically cause pile foundation main muscle 5 top by an end joint outside pile foundation wherein a main muscle 5, and reserved free segment 30cm.After being in place, all brushing release agent is together for PVC sleeve pipe 1, rubber hose 2.
2), by the reinforcing cage processed put into stake holes, pile foundation concrete can be built after the assay was approved.
3), pile foundation concrete reaches some strength, as: after 70%, carry out invalid pile crown and abolish construction, the artificial free segment firmly drawing rubber hose 2 in certain direction, thin wall concrete that is vertical and design elevation position horizontal segment outside rubber hose 2 is caused to come off, and take out rubber hose 2, now form a circle horizontal groove around pile body, it is high that this horizontal level is design stake top mark.
4), adopt pneumatic pick along described horizontal groove at interval of certain distance to pile body centre-drilling hole, drilling depth controls at 20cm, in boring, squeeze into steel after having holed carve 4, steel engraving tool 4 is squeezed in process and is frequently upwards prized for several times, due to plain concrete fragility characteristic, form horizontal breaking face at concrete groove position, effective pile body part 11 is all blocked with invalid pile body part 10 and is separated.
5), link closely firmly by lifting rope 6 and hoisting ring 3, adopt the lifting appliances such as backhoe will block pile body lifting, pile crown has been abolished.Remove the PVC sleeve pipe 1 that the main muscle 5 of pile foundation, sound detecting pipe 8 are inserted in advance, cleaning pile crown can carry out the pier stud construction of pile foundation top.
