Description
Technical field
The present invention relates to construction of prefabricated piles technical field, be specifically related to a kind of deep or the embedding rock of ultra-deep is pre-
Pile driving construction equipment processed and construction method.
Background technology
In riverine, coastal area, widely distributed intensity is low, moisture content is high, compressibility is high,
The weak soil that permeability is low, thickness is big, its physico-mechanical properties is poor, in high-rise or high-rise stake
Basis is the most embedding relatively deep, uses prefabricated pile to be difficult to pile sinking, and to easily snap off, the highest
Layer or high-rise pile foundation generally use bored concrete pile technology, during common filling pile construction
To produce a large amount of mud, easy collapse hole, shrinkage cavity, sediment at the bottom of hole is difficult to clear up, is difficult in weak soil
Ensure pile quality, and casing original state soil taking and filling pile work progress need to fetch earth, when the soil body becomes soft
Moulding or be difficult to fetch earth successfully during liquid-plastic state, in casing, sediment is difficult to clear up, and speed of application is slow,
When there is mild wind, mild wind, middle air slaking or hard subjacent bed, the embedding rock of common filling pile is relatively
For difficulty, prefabricated pile is more difficult to.
By patent retrieval, there is following known technical scheme:
Patent 1:
Application number: 03124315.0, the applying date: 2003-04-30, authorized announcement date: 2003-11-26,
A kind of combined rock-embedding pile, including the pile cutoff being positioned in soil layer and the pile cutoff being positioned in rock stratum, described
Pile cutoff in soil layer and the pile cutoff in rock stratum link together, and described combined rock-embedding pile also comprises to be filled out
Fill material.Wherein, the pile cutoff in the soil layer of the present invention can be by prefabricated (including prestressing force) steel
Perfusion packing material in reinforced concrete sleeve pipe or steel pipe, and Section-steel Piles outsourcing packing material two kinds
Component is selected one.Pile cutoff in the rock stratum of the present invention can be by steel reinforcement cage, steel beam column and pre-
Reinforced concrete member these three component processed is selected a kind of or combination in any, formation pore is inoculated with
Described packing material.Pile body in petrosal foramen expands load by the cohesive force of packing material and petrosal foramen wall
It is scattered to depths, rock stratum, owing to its contact area with packing material is more than using the stake of normal configuration,
Therefore anchor force can be fully provided.
Patent 2:
Application number: 02121959.1, the applying date: 2002-05-28, authorized announcement date: 2002-12-25,
The invention discloses a kind of combined rock-embedding pile and construction method thereof, with prefabricated reinforced concrete pipe or other
Stake adds additional bar as the bearing carrier in soil layer, adds additional bar or pre-with reinforcing bar or component
Reinforced concrete member processed is inserted in deeper preboring petrosal foramen, then imposes the group that on-the-spot grouting material is formed
Closing stake, one of which reinforcing bar is through and waters the inside being fixed in above-mentioned component to bear pressure or pulling force,
And improve the seriality between pile cutoff, it is positioned at the pile body dependence of petrosal foramen and cohering of petrosal foramen sidewall
Power is uniformly spread to depths, rock stratum the load transmitted above.Owing to the bearing area of stake is than existing
The pure end having technology holds formula stake and is significantly increased, and its grouting material is the biggest with the adhesion of rock
Frictional force between the pure friction pile and soil of prior art, thus substantially increase whole stake
Bearing capacity.Due to all components of whole stake can industrial mass production, therefore can simplify design, side
Just construct, reduce cost.
Patent 3:
Application number: 200510084145.5, the applying date: 2005-07-14, authorized announcement date:
2007-01-17, a kind of steel-pipe concrete assembled pile of predrilled hole rock-embedded, including the steel with high intensity
Pipe shell and high compressive strength, the concrete of big rigidity or armored concrete inner core, described embedding rock
The cementitious packing material of in-site pouring is gone back between concrete filled steel tube built pile and preboring stake holes.In advance
Pile body in boring is diffused into rock stratum by the cohesive force of above-mentioned packing material and hole wall vertical load
Depths, is delivered to horizontal loading in surrounding soil.Owing to the present invention utilizes existing steel tube concrete
The excellent stress performance of earth pillar and embedded rock pile high-bearing capacity overcast by feature, make each of pile foundation
Plant bearing capacity, horizontal force resistant rigidity, construction quality and cost performance and other existing concreting in site
Concrete-pile is compared, and is all improved largely.
Being found by above retrieval, above technical scheme does not affect the novelty of the present invention；
And above patent document be mutually combined the creativeness not destroying the present invention.

One the most according to claim 8 is deep or ultra-deep embedding rock construction of prefabricated piles method, its
Be characterised by: step 3) in reversion rollback drilling rod (3) time select to stop according to the intensity of soil cement
Slurry reversion rollback drilling rod (3) or whitewashing reversion rollback drilling rod (3).
One the most according to claim 8 is deep or ultra-deep embedding rock construction of prefabricated piles method,
It is characterized in that: step 4) described in pile top basal diameter less than prefabricated pile diameter, more than drill bit
(3) diameter and light circle casing (1) or the difference of Flos Mume casing (2) diameter, pile top inclined-plane inclines
Tiltedly degree is equal with inverted cone inclined-plane (403) inclined degree of drill bit (3).
