Description
[technical field]
This utility model is related to technical field of civil engineering, and specifically one kind bores vibration major diameter PHC pipe for interior
The pile-sinking device of stake.
[background technology]
PHC pile tube, full name is prestressed high-strength concrete pile, is to adopt pretensioned prestressing and centrifugation in professional factory
Moulding process, a kind of pile tube made through steam press maintenance.
With the high speed expansion in city, the infrastructure construction such as high-speed railway, highway, port and pier, bridge spanning the sea
Extensive development, because PHC concrete precast pile is quick for installation, convenient, steady quality, the advantages of save the engineering time,
Current utilization is more and more wider.It is reported that, China PHC pile tube yield reaches 3.5 hundred million meters within 2011.
The main method of heavy PHC pile tube is as follows at present：
(1) plunging.As prefabricated pile is pressed into underground by self gravitation by Static pressure pile driver.Its advantage is tranquility environmental protection, but sets
The shortcoming of standby both bulk, the soil layer jacked pile more than hard formation particularly medium coarse sand is highly difficult.
(2) squeeze into method.Hit with diesel hammer or hydraulic hammer and sink to.Its advantage is efficiency high, but shortcoming is noise, vibrates greatly,
And the soil layer driven pile more than medium coarse sand is highly difficult.
(3) implantation.External more of this method, construction is seldom at home.It is first to use drill hole of drilling machine, fills in the hole
Cement injection, then prefabricated pile is implanted in the hole.Its advantage is non-soil compaction and environmental protection, but shortcoming to be efficiency of construction relatively low, and cold
Cold day gas cannot be constructed due to freezing slurry.
(4) middle pick method.This method is Japanese's invention, and it is particularly well-suited to the construction of the prefabricated pile of major diameter.Advantage is
Non- soil compaction and environmental protection, but the shortcoming huge, equipment that is device systems and construction cost is high, efficiency is low.
(5) vibratory drilling method.This method makes a soil resistance reduce using vibration, reaches pile sinking purpose under gravity.Its advantage
It is that equipment is simple, efficiency of construction is high, but has vibration effect, and typically can not sink to severely-weathered above soil layer.
Now, PHC concrete precast pile pile tube gets more and more used in the basic aspect of heavy construction, and the base of heavy construction
Plinth stake generally requires PHC tube pile of major diameter, and PHC tube pile of major diameter is sunk to soil layer, particularly sinks to the soil of more than medium coarse sand
Layer is highly difficult with existing method, and high cost, efficiency are low.
[utility model content]
The purpose of this utility model is to solve the deficiencies in the prior art, provides and bores vibration PHC tube pile of major diameter in one kind
Pile-sinking device, for large-diameter tubular pile hollow feature, in conjunction with the Construction Principle of vibrohammer and rig, give full play to each excellent
Point, rationally carries out construction operation.It was both fetched earth in pile tube using rig, reduced end resistance, reduced stake soil using vibration again
Resistance, acts on reaching pile sinking purpose in conjunction with two machines.
To achieve these goals, a kind of pile-sinking device for interior brill vibration PHC tube pile of major diameter of design, common including exempting from
Center of percussion hole vibration hammer, pile tube fixture, long-spiral drilling machine, drilling rod and pile frame are it is characterised in that exempt to resonate mesopore vibration hammer by pipe
Pile holder tool clamping pile tube, is provided with drilling rod in pile tube, drilling rod top connects long-spiral drilling machine, described exempt to resonate mesopore vibration hammer and
Long-spiral drilling machine is connected with pile frame.
Described resonance mesopore vibration hammer of exempting from includes power-driven mechanism, eccentric shaft assembly, in described drive mechanism
Motor using the resistance to motor that shakes of frequency conversion, described eccentric shaft assembly comprises multiple eccentric shafts, between described eccentric shaft according to
Secondary be connected, described eccentric shaft assembly the first eccentric shaft near end is power input shaft, in addition eccentric shaft be dynamic
Power output shaft, described power input shaft, the rearward end of power output shaft is fixedly installed gear, centre position is provided with
Eccentric block, described power input shaft axle head is provided with belt pulley.
This utility model compared with the existing technology, has an advantage in that：
1. can operate with any soil layer, you can suitable under quicksand, mud, sandy gravel and easy collapse hole and underground bearing water geology
Complete pile sinking sharply；
2. no " resonate " harm, retaining wall, fetch earth is carried out simultaneously, pile sinking efficiency high；
3. rig fetches earth the soil only taking in pile tube endoporus, and genus part fetches earth.Both can guarantee that enough side frictions, reduced again
The adverse effect that full soil compaction is brought；
4. it is not required to mud etc., not only civilization was dry clean but also was protected from weather influences for construction.
