Description
Technical field
The present invention relates to field of civil engineering, particularly relate to the construction method of a kind of uplift pile.
Background technology
Along with building improving constantly of scientific and technological level, the requirement to building pile basis is strengthened the most accordingly, many times stake
Base not only needs compressive resistance, in addition it is also necessary to provide certain withdrawal resistance.In the patent documentation of the patent No. 98124854.3, it is provided that
The construction method of a kind of concrete deadman, by the steel reinforcement cage of a kind of expandable diameter part, and the method rammed with filler is by reinforcing bar
The expandable diameter part of cage spreads, and forms enlarged footing in stake end.But finding in being embodied as, what the method existed mainly asks
Topic, one is that the weight energy owing to using is very big, and the hammer end the most directly impacts on the reinforcing bar of expandable diameter part, easily causes reinforcing bar
Sheared and fractureed, thus lost withdrawal resistance；Two is although that the internal layer of expandable diameter part reinforcing bar is filled with compacted filler, but steel
The outer layer of muscle but only has original state soil layer, so the reinforcing bar of expandable diameter part does not has filled sufficient parcel；Three is complete with expanding
The frictional force of footpath portion reinforcing bar and enlarged footing provides withdrawal resistance, and the withdrawal resistance that therefore this kind of method is provided is insufficient, unstable.
Summary of the invention
The present invention is in order to solve above-mentioned problem and to propose, it is therefore intended that provide the construction method of a kind of uplift pile,
By the method can rapidly and efficiently formed a kind of anchoring pile possessing higher withdrawal resistance, or formed a kind of have simultaneously higher
Compressive Bearing Capacity and the concrete-pile of withdrawal resistance.
To achieve these goals, the construction method of the uplift pile of the present invention comprises the steps:
1) at stake position, casing is drowned into set depth；
2) inserting cement mixture in casing, described cement mixture is the blended stirring of main material by cement and sand and water
Form, by the way of hammering, the cement mixture inserted is rammed, form the bottom of carrier at stake end；
3) sinking to special anchoring piece in casing, described anchoring piece is made up of vertical anchor rod and bottom anchor dish, vertical anchor
Gu bar is made up of a reinforcing bar or many tendons, bottom anchor dish is made by reinforcing bar or steel plate, the diameter of bottom anchor dish
Internal diameter less than casing；
4) with the vertical anchor rod of anchoring piece as SMIS, sinking to punching hammer in casing, the internal diameter of described punching hammer is more than vertical
The diameter of anchor rod and external diameter are less than the internal diameter of casing；
5) inserting cement mixture in casing, cement mixture gap between punching hammer outer wall and casing inwall falls within
On bottom anchor dish；
6) in casing, promote punching hammer, ram inserted cement mixture with low away from, little energy；
7) repeat the above steps 5) and 6) insert cement mixture and hammer, with punching, the operation rammed into shape, the most gradually add
The heavy tamping energy of big punching hammer, thus the carrier possessing certain volume and degree of compaction is gradually formed at stake end, and by anchoring piece
Within bottom anchor dish parcel is mounted in carrier；
8) one of following method is used to carry out subsequent construction:
1. in casing, propose casing after cement injection mortar or plain concrete, form Pulling-Resistant Anchor Rod stake；
2. propose casing after sinking to steel reinforcement cage, concrete perfusion in casing, form pulling-resistant and pressure-resistant reinforced concrete pile.
In above-mentioned construction method, preferably, above-mentioned steps 1) described in the mode that institute's cylinder sinks to is included following method
One of or combination: 1. in casing place weight, utilize the impact kinetic energy of weight that foundation soil body is punched out, formed stake holes
Backward it is lowered into casing；2. use diesel hammer or hydraulic hammer or automatic mallet to drive inner tube to ram casing, make inner tube and casing
Synchronization is sunk to；3., after using the mode soil taking hole forming of auger or churning driven or manually digging hole, casing is sunk in stake holes；④
Use hammering or vibration or the mode of static pressure, by the casing with pile top precast pile tip or flapper pile tip to being lowered into.
In above-mentioned construction method, preferably, above-mentioned steps 3) described in vertical anchor rod in reinforcing bar be prestress steel
Muscle or regular reinforcement, described vertical anchor rod also is able to use fine steel tube or steel strand manufacturing.
In above-mentioned construction method, preferably, above-mentioned steps 2) and 5) described in cement mixture can also add granule
Footpath rubble and concrete admixture, between the maximum particle diameter of this cement mixture is less than between punching hammer outer wall and casing inwall
Gap.
In above-mentioned construction method, preferably, above-mentioned steps 6) and step 7) during, punching during punching hammer when being lifted up
The bottom of hammer suitable for reading without departing from casing all the time.
In above-mentioned construction method, preferably, above-mentioned steps 7) in, number can be used to hit pile penetration or with cement mixture
Insert quantity and control a degree of compaction for end carrier.
In above-mentioned construction method, preferably, above-mentioned steps 7) in carrier construction terminate after, can continue to construct one or
The expanding body of multiple continuous print, the construction method of this expanding body is: be lifted up casing certain altitude, insert cement mixture and with
Punching hammer is rammed.
Feature and the advantage of the present invention are:
1. fully improve withdrawal resistance from following many aspects: first, use special anchoring piece, and by the bottom anchor in anchoring piece
Gu dish build-in is wrapped in an end carrier, its build-in effect and breakout capacity significantly improve；Second, stake end carrier uses cement to mix
Compound is filler, and cement mixture density after curing and intensity are all much stronger than common compacted filler, increase further
The build-in effect of carrier and anchoring piece, the cement mixture of stake end carrier can be with the material such as pile concrete or mortar simultaneously
Hardening is combined as a whole, and more enhances pile quality and resistance to compression breakout capacity；3rd, by carry after casing certain altitude again
Carry out cement mixture fills out rammer, can form one or more continuous expanding body, to surrounding soil on stake end carrier
Carry out reinforcing compacted while strengthen pile body area, thus improve resistance to compression and the breakout capacity of stake further；4th, to anchoring
In the process of part, before and after employing, fill out the mode of rammer for twice so that bottom anchor dish can fully be wrapped in an end carrier, also
Avoid anchoring piece with in the soil body water and air contact generation corrosion.
2. from following many aspects raising work efficiency and quality: first, punching hammer is used to mate use with special anchoring piece,
The fast work efficiency of speed of application is high；Second, punching hammer is bottom suitable for reading without departing from casing all the time when being lifted up, and requires that cement is mixed simultaneously
Compound can be carried out while therefore realizing filler and hammering through the gap punching hammer and casing, it is to avoid weight originally
Hammer must propose the backward means just can rammed after casing mouth waits filler, it is ensured that continual hammering continuous doing work, significantly carries
High efficiency；3rd, use more low-yield during filling out rammer, therefore cement mixture is to be added when slowly extruding
Gu compacted, even if in the case of rich groundwater, the liquefaction of soil mass also not resulted in and softening, it is to avoid mud or water enter stake
Body bottom, significantly improves carrier and pile quality.
3. the method can form two kinds of pile-type, the purest Pulling-Resistant Anchor Rod stake and resistance to compression resistance to plucking carrier pile, different to be applicable to
Building and design requirement.
