Abstract
The present invention provides a construction method for concrete piles, which is characterized in that a concrete pile with high bearing capacity can be formed in a hard foundation by low cost to meet the requirements of high-rise buildings and structural objects with high bearing capacity requirements. The method comprises the following steps: a) drilling a hole by a screw drill rod on the foundation of a pile position till a specified depth, and then lifting the screw drill rod out by reverse rotation to form a guide hole of a pile; b) putting a protective drum of which the external surface is provided with helical blades into the guide hole of the pile, wherein the total diameter of the protective drum and the helical blades is larger than the diameter of the guide hole of the pile; putting a guide member into the protective drum, and rotating the protective drum along the guide hole of the pile under the guide of the guide member to drive the protective drum to move downward till a specified depth; and c) carry outing the construction of the pile body, and lifting the protective drum by reverse rotation in the construction.
Description
Technical field
The present invention relates to the construction technology of foundation, particularly relate to the construction technology of concrete pile.
Background technology
In the past, in construction, once had the construction technology of following concrete pile, this technology is characterised in that by the mode of hammering with pipe, casing is arranged at the prescribed depth of ground, at the complex carrier of soil layer formation preferably, make pile body then, thus, transfer the following soil layer preferably of stake end fully, the bearing capacity that is the soil body of bearing stratum participates in stressed, thereby the cost of above-mentioned construction technology is lower, but the shortcoming of this construction technology is that it only is suitable for softer ground soil condition, such as, the foundation surface layer, compactness is less, loose silt, silty clay etc., and be not suitable for hardpan, the darker soil layer apart from ground, such as, the powder soil horizon that compactness is bigger, powder fine sand soil layer, coarse sands layer, cobble layers etc. that is to say, when running into above-mentioned hardpan, be difficult to by the mode of hammering with pipe, casing is arranged at the prescribed depth of ground, and consequently, above-mentioned construction technology is used for more shallow foundation soil mostly, it is not too high to make bearing capacity, the pile foundation that low-rise building is used, and be not suitable in darker foundation soil, such as, it is higher to make bearing capacity through the foundation ditch bottom surface of excavation, the pile foundation that high-rise building is used still, is followed the metropolis, such as, the high stratification of the building of Beijing, the market of the foundation that high-rise building is used is more and more, therefore, people are desirable to provide a kind of these needs that satisfy, the construction technology of the stake that cost is still low.
Summary of the invention
The object of the present invention is to provide a kind of job practices of concrete pile, the job practices of this concrete pile can be made the higher concrete pile of bearing capacity with lower cost in harder ground, so that satisfy high-rise building, the requirement of the works that requirement for bearing capacity is higher.
The objective of the invention is that job practices by following concrete pile realizes, this job practices comprises the steps:
A) in the ground at place, stake position, hole by auger stem, until the prescribed depth place, counter-rotating proposes auger stem then, forms the pilot hole of stake;
B) casing that external surface is had helical blade is put into the pilot hole of above-mentioned stake, the overall diameter of this casing and helical blade is greater than the diameter of the pilot hole of above-mentioned stake, in this casing, put into guide, under the guiding of above-mentioned guide, pilot hole along above-mentioned stake, above-mentioned casing is rotated and it is moved down, until prescribed depth;
C) carry out the construction of pile body, in this work progress, counter-rotating proposes above-mentioned casing.
If adopt the job practices of above-mentioned concrete pile, can in harder soil layer, carry out pore-forming apace, carry out the construction of concrete pile, it is higher to adapt to the bigger bearing capacity in market, such as, the needs of high-rise building.In addition, can make the stake of larger diameter.In addition, because the effect of guide can prevent that above-mentioned casing from deflection taking place in sinking to process.
In the job practices of above-mentioned concrete pile, best, the diameter of this casing equals the diameter of the pilot hole of above-mentioned stake.
According to such scheme, can utilize pilot hole most effectively, casing is sunk in the ground.
In the job practices of above-mentioned concrete pile, best, the construction of the pile body above-mentioned steps c) comprises the steps: 1) pass through this casing to bottom, stake hole, building waste is inserted in gradation, makes weight do elevating movement along this casing inside, and the building waste of being inserted is rammed, make the soil body of certain limit under the stake end obtain reinforcing closely knit, carry out aforesaid operations repeatedly, until satisfying the degree of ramming, this is rammed degree and determines according to three modes of hitting the injection amount in the complex carrier compaction pile design discipline; 2) by this casing, to bottom, stake hole, harsh concrete is inserted in gradation, this harsh concrete always the amount of inserting at 0.3～1m
3Scope in, and, make weight do elevating movement along the inside of this casing less than the amount of inserting always of building waste, the harsh concrete of being inserted is rammed; 3) the casing counter-rotating is promoted 30cm～50cm, insert harsh concrete once more, it is tamped, thereby form complex carrier; 4) place reinforcing cage in above-mentioned casing, Yi Bian pour into a mould vibrated concrete, Yi Bian counter-rotating promotes above-mentioned casing, the soil body back-out with the casing outer wall until proposing casing fully, forms pile body.
According to above-mentioned scheme, the concrete stake of complex carrier can be combined with technology of passing through hardpan of the present invention, make the concrete stake of complex carrier give full play to foundation soil body and participate in stressedly that characteristics are brought into play cheaply simultaneously in the ground of hardpan.
In the job practices of above-mentioned concrete pile, best, when this pile concrete of cast, vibrator is set in the casing bottom, concrete is vibrated.
According to above-mentioned scheme, can guarantee the bond quality between stake bottom cast-in-situ concrete and the harsh concrete.
In the job practices of above-mentioned concrete pile, best, above-mentioned guide adopts weight, above-mentioned steps b) described in the guiding of guide refer to weight be passed the bottom of above-mentioned casing and stretch out, a part that is weight in casing, the state of another part in pilot hole.
According to above-mentioned scheme, when the technology with the complex carrier concrete pile combines with the present invention, weight is used as guide, and guide needn't be set separately, can reduce the quantity of the building block of construction equipment, reduce cost.
In the job practices of above-mentioned concrete pile, best, above-mentioned to pass through action that auger stem holes be that the stake position is being carried out under the state of borehole in advance.
According to above-mentioned scheme, can realize auger boring first more easily.
In the job practices of above-mentioned concrete pile, best, the diameter of this casing is less than the diameter of the pilot hole of above-mentioned stake.
According to above-mentioned scheme, can prevent in the process that screws off of casing, soil body particle is dropped at the bottom of the hole and form loosened soil.
In the job practices of above-mentioned concrete pile, the construction of the pile body best, above-mentioned steps c) comprises according to complex carrier compaction pile design discipline, in the casing bottom to soil layer preferably between the bearing stratum, the soil body is reinforced compacted processing, make the complex carrier of stake bottom.
During pile body in forming pile body, preformed pile is inserted in the above-mentioned retaining wall cylindrical shell, above-mentioned casing counter-rotating is proposed, fluid concrete or mortar in the gap between above-mentioned preformed pile and the hole.
