Description
Technical field
The invention belongs to technical field of bridge construction, and in particular to a kind of permanent protecting tube embedding construction of bridge pier column outsourcing
Method, the method for excavating exposed permanent protecting tube embedding construction afterwards of first constructing especially suitable for bridge pier column.
Background technique
General protecting tube embedding method, using vibration hammer inserting piling steel pile casting.When vibration hammer operates, under the action of eccentric hammer
High-frequency vibration is generated, high frequency vibrating power acts on steel pile casting by hydraulic gripper, then the ground being in contact with it is transmitted to by steel pile casting
Layer makes the contact surface for contacting stratum generate " liquefaction ".Vibration hammer clamper and steel pile casting are under the action of exciting force and self weight, no
It is disconnected to sink to stratum, to then hollow out soil in steel pile casting in steel pile casting inserting piling to soil layer, sinking frictional resistance is reduced, so
After continue with vibration hammer inserting piling until inserting piling branch design altitude.But since geological layering is uneven, situations such as containing erratic boulder, vibration
Inserting piling steel pile casting is hammered into shape it is difficult to ensure that the accurate positioning of steel pile casting is spent with vertical, and steel pile casting is easily deformed, damaged.
Summary of the invention
To solve the existing deficiency of engineering technology, the purpose of the present invention is to propose to a kind of bridge pier column outsourcing permanent steel shield
Cylinder burial and construction method.
The present invention adopts the following technical solutions to accomplish the above objectives:
A kind of permanent protecting tube embedding construction method of bridge pier column outsourcing, the specific steps of which are as follows:
1) bridge pier steel pile casting is processed, winds 4~6 layers of plastic film in bridge pier steel pile casting outer wall；
2) surveying and locating determines the burial place of bridge pier steel pile casting；
3) rotary drilling rig is in place and starts to perform construction pilot hole, the big 40cm of aperture ratio bridge pier steel pile casting outer diameter；
4) when drilling to bridge pier protecting tube embedding bottom absolute altitude, downward outdrill 50cm；
5) it to the clay for the construction pilot hole bottom backfill 100cm being drilled with, is inverted using rotary drilling rig and is compacted clay；
6) the bridge pier steel pile casting that outside wall surface is wound with plastic film is hung in construction pilot hole, and be accurately positioned, then by bridge
Pier steel pile casting is pressed into clay 50cm；
7) bridge pier steel pile casting upper surface is open and is accurately positioned and is fixed with timber wedge, the timber wedge is outside bridge pier steel pile casting
Wall surface and the multiple bolts for performing between pilot hole inner wall, being uniformly distributed along the circumference, in bridge pier steel pile casting and perform pilot hole inner wall
Concrete between wall is poured in gap between face；
8) after concrete reaches intensity between wall, the bolt is taken down, boring steel pile casting is installed；Boring steel pile casting
Internal diameter is greater than the internal diameter of bridge pier steel pile casting；The lower end of the boring steel pile casting is supported between the wall on concrete, on
Distal process backfills clay for described performs pilot hole, in the gap between pilot hole and boring steel pile casting and tamps；
9) rotary drilling rig continues drilling to stake bottom absolute altitude, and bridge pile foundation steel bar cage is installed in hole, pours pile foundation concrete to setting
Absolute altitude, and superfilled 50cm are counted, boring steel pile casting is pulled out；
10) after pile foundation concrete reaches intensity, pile crown is excavated and cut, carries out pile measurement, bent cap of constructing after detection is qualified
And superstructure；
11) after the completion of the construction of other structures object, the earthwork under bridge is excavated, by steel pile casting outer wall concrete chisel removal, it is thin to remove plastics
Film brushes antirusting paint.
The permanent protecting tube embedding construction method of a kind of bridge pier column outsourcing proposed by the present invention, by adopting the above technical scheme,
Compared to existing protecting tube embedding construction method, the present invention is accurately positioned simultaneously fixed steel pile casting by construction pilot hole, and hole wall with
The method of concrete perfusion between steel pile casting outer wall, while guaranteeing that steel pile casting is accurately positioned and spends vertically, steel pile casting is not variable
Shape, damage, and image appearance is good after excavation；The characteristics of this method is adaptable strong, convenient for construction, simple process simultaneously.
