Description

A kind of construction method of castinplace pile
Technical field
The present invention relates to building foundation engineering technical field, particularly a kind of construction method of castinplace pile.
Background technology
Friction when castinplace pile has a construction, without the advantage such as soil compaction, noise be little, to be widely applied in all kinds of civil construction project.In perfusion formation of pile, due to cement paste returning, in filling process, pile body top falls into the reason such as earth, impurity unavoidably, and pile crown intensity can be caused to be difficult to ensure, therefore needs superly to fill with a part of pile body, is abolished, i.e. broken pile head in the later stage.Traditional filling pile construction flow process can be summarized as: levelling of the land, surveying setting-out, bury casing, boring and clear hole underground, lay reinforcing cage, hang conduit, concrete perfusion, dismounting conduit, excavate inter-pile soil, broken pile head.
In above-mentioned traditional construction flow process; broken pile head operation is carried out after pile body filling concrete completes and reaches some strength or design strength; first excavate inter-pile soil to the super complete exposure of pile body of filling with part; for the pile body of super filling; it exceeds the instruments such as reinforcing cage main muscle part emery wheel and blocks; concrete cover outside main muscle is carefully destroyed by the instrument such as part pneumatic pick containing main muscle, and confirm that main reinforce position descendant hammer hits bore bit, at design of pile top absolute altitude place, support is disconnected.This traditional cast-in-place pile construction method, is subject to the restriction of main muscle, and the labour intensity of workman's broken pile head is very large, and operating efficiency is very low.
Summary of the invention
The present invention is to solve the problem, and provides a kind of easy construction, is conducive to the cast-in-place pile construction method of quick broken pile head.
Technical scheme of the present invention is: a kind of cast-in-place pile construction method, comprises the following steps:
(1) excavate ground: excavation original ground or foundation trench bottom surface, cutting depth should ensure more than the ground of super filling part pile body all after excavation, and reserves the degree of depth that pile body top embeds cushion cap, and super part pile body height of filling with should not be less than 80cm;
(2) stake holes is formed: on the construction ground that excavation is formed afterwards, bury the casing with flange I underground, casing installs and should ensure that casing end face absolute altitude is for design stake top mark is high or in specification allowable variation, take casing as guiding punching, form satisfactory stake holes;
(3) lower sleeve is installed: the lower sleeve with flange II is installed on casing, with bolt, lower sleeve and casing is pasted close linking together; Described lower sleeve internal diameter is identical with casing, high 10 ~ 15cm, and its upper mouth has circumferential semi-circular recesses, and number of recesses is identical with the quantity of muscle main in reinforcing cage, groove diameter 0.5 ~ 1.0cm larger than main muscle diameter;
(4) lay reinforcing cage, bend main muscle: be placed in stake holes by reinforcing cage, and main for reinforcing cage corresponding for lower sleeve upper mouth groove bottom muscle position is bent, make the protruding groove of main muscle of more than bending place;
(5) install sleeve: the upper bush with flange III is installed on lower sleeve, with bolt, upper bush and lower sleeve are pasted close linking together; Described upper bush internal diameter is identical with lower sleeve, upper bush height be super fill with part pile body high deduct lower sleeve high (height of super perfusion part pile body be lower sleeve and upper bush height and), the lower edge mouth of upper bush has circumferential semi-circular recesses, and the quantity of groove is identical with the groove arranged in lower sleeve with diameter; After upper bush installation, the respective slot of its each groove and aforementioned lower sleeve forms circular hole;
(6) concrete perfusion: hang conduit, continous pouring pile body concrete rises to concrete surface and flushes with upper bush end face;
(7) remove upper bush: after pile body filling concrete completes, extract conduit, removed by upper bush, casing is stayed in the soil body, and now lower sleeve is still arranged on casing;
(8) part super filling pile crown is abolished: after removing upper bush, if the not yet initial set of the concrete in upper bush, with smooth stiff sheet from lower sleeve upper mouth by the concordant excision of this part concrete, if this part concrete initial set, after final set by its with cutting tools such as emery wheels from lower sleeve upper mouth by its concordant excision;
(9) main muscle straightening, abolishes residue super filling pile crown: after pile body concrete reaches design strength, by the main muscle straightening of bending, remove lower sleeve, and artificial chisel is except a small amount of surpassing remaining in lower sleeve filling with concrete; When super filling pile crown is all abolished complete, upwards extract casing.
Further, the inwall of described lower sleeve and upper bush all scribbles concrete isolation agent;
Further, in described step (4), the angle of bending is no more than 90 degree;
Further, the wall thickness of described lower sleeve and upper bush is all no more than casing wall thickness;
Further, in described step (7), remove upper bush and carry out immediately after extracting conduit, or carry out after pile body concrete curing a period of time;
Further, described stiff sheet is steel plate or plank, and plate is wide is not less than pile body diameter;
Further, in described step (4), adopt Portable reinforcing steel bar to bend stretching all-in-one and bend main muscle;
Further, in described step (9), Portable reinforcing steel bar is adopted to bend the main muscle of stretching all-in-one straightening.
beneficial effect of the present invention
The invention provides a kind of new method of filling pile construction, by preposition for the operation excavating inter-pile soil before broken pile head in conventional construction method, pile body has poured into can abolish super major part (also can abolish after health a period of time) of filling with pile crown easily and efficiently, small part pile crown is only stayed manually to abolish after reaching design strength, easy construction, greatly reduce the labour intensity of workman's broken pile head construction, improve efficiency of construction.Because the main muscle in reinforcing cage has carried out outside bending process in the bottom of lower jacket casing groove, therefore the pile body in upper bush is not containing main muscle, this part pile body can be abolished easily after removing upper bush, super pile crown of filling with is arranged in the part of lower sleeve when manually abolishing, due to have lower sleeve as mark instruction, there will not be super broken and damage pile body situation.Main muscle bending in the present invention and the connection of casing and sleeve can also play the effect of fixing reinforcing cage position, to make it in filling concrete not off normal, non-rising.The casing with flange used in the present invention, sleeve, connecting bolt etc. all can have enough to meet the need use, cost-saving.
