Description
Technical field
The utility model relates to the pile foundation constructions of Large Diameter Super-long Bored Piles in river, are especially for river
The integrated dedicated positioning device of pile foundation steel bar cage and steel pile casting.
Background technique
In Large Diameter Super-long Bored Piles pile foundation construction, generally in 2m or more, designing pile length exists main bridge Pile Diameter
83-100m；Access bridge Pile Diameter is generally 1.8m, designing pile length 47-64m；15m below pile foundation top surface has additional directly in main stem
Diameter is the permanent steel pile casting of 2.2m, wall thickness 20mm, and the every section 12m of steel reinforcement cage used in pile foundation is at the construction field (site) in steel bar meter field
It is made, the weight of every section steel reinforcement cage is about 3t, and single pile foundation steel bar cage maximum weight is 21t, each permanent steel pile casting weight
Up to 15t.
In pile foundation construction, traditional steel reinforcement cage lowering operation is generally fixed using rod, such fixing means built on the sand, work
People's construction is very dangerous, and causes main reinforcement sleeve to be not easy to dock using rod fixed steel bars cage；Meanwhile permanent steel pile casting suspention
There are still difficulty for decentralization positioning greatly, construction insecurity factor.
Summary of the invention
The utility model aim is to provide a kind of dedicated positioning of the integration for river pile foundation steel bar cage and steel pile casting
Device.
To achieve the above object, the utility model takes following technical proposals:
Integrated dedicated positioning device described in the utility model for river pile foundation steel bar cage and steel pile casting, including positioning
Platform is provided with through thereon in the middle part of the locating platform, the positioning tube of following table, has been uniformly arranged at least three in locating platform
Locating platform lateral wall is extended in one end sliding of a positioning pluging rod, each positioning pluging rod and other end sliding extends to institute
It states in positioning tube.
Each positioning pluging rod is horizontally disposed each along the radial direction of the positioning tube, in the locating platform side wall
On be uniformly arranged multiple lifting lugs.
The both ends of each positioning pluging rod are respectively arranged with locking pin.
Its axial direction is provided with graduated scale on the positioning tube inner wall.
The positioning pluging rod is vertical plate structure.
The utility model aims at the positioning in construction of river pile foundation steel bar cage and permanent steel pile casting and designs, and utilizes positioning
Inserted link hangs steel reinforcement cage and permanent steel pile casting.It the advantage is that the positioning accurate that both ensure that steel reinforcement cage and the decentralization of permanent steel pile casting
Degree, and construction efficiency is improved, the decentralization positioning operation time of steel reinforcement cage and permanent steel pile casting is saved, while also grasping for worker
Provide safe operation platform.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, the dedicated positioning of the integration described in the utility model for river pile foundation steel bar cage and steel pile casting
Device, the locating platform 1 including square structure are provided in the middle part of locating platform through thereon, the positioning tube 2 of following table,
The radius R1 of positioning tube 2 is greater than the radius R2 of permanent steel pile casting 3 and the radius R3 of steel reinforcement cage 4, along its axial direction on 2 inner wall of positioning tube
It is provided with graduated scale 5, is uniformly arranged on 1 side wall of locating platform there are four lifting lug 6.
The uniformly distributed positioning pluging rod 7 there are six along the setting of 2 radial direction of positioning tube in locating platform 1, positioning pluging rod 7 are vertical plate
1 lateral wall of locating platform is extended in one end sliding of structure, six positioning pluging rods 7 and other end sliding extends in positioning tube 2,
The both ends of each positioning pluging rod 7 are respectively arranged with locking pin 8.1,8.2；The effect of locking pin 8.1 be in order to prevent steel reinforcement cage 4 and
It falls off on the self-positioning inserted link 7 of permanent steel pile casting 3, the effect of locking pin 8.2 is for the ease of positioning pluging rod 7 into and out behaviour
Make.
To further increase positioning accuracy, its axial direction is provided with graduated scale 9 on 2 inner wall of positioning tube.
In use, after drilling machine mentions brill, it is smooth to the progress of stake holes aperture periphery place, cross shield is gone out according to the setting-out of stake holes center
Stake slings locating platform 1 by lifting appliance, and adjustment 2 central point of positioning tube is overlapped with the central point of pile foundation.
Permanent steel pile casting 3 and steel reinforcement cage 4 are suspended on positioning pluging rod 7 by hangs muscle, and permanent steel pile casting 3 is hung using two
Point, steel reinforcement cage 4 use four suspension centres.
When the hangs muscle of permanent steel pile casting 3, the hangs muscle of steel reinforcement cage 4 are each located on the identical quarter of 2 inner wall high scale ruler 9 of positioning tube
When on degree, illustrate that permanent steel pile casting 3 and 4 central point of steel reinforcement cage are overlapped with 4 central point of pile foundation steel bar cage, thus adjusts permanent steel
The deviation that casing 3 and steel reinforcement cage 4 are transferred, improves the precision of decentralization.
Permanent steel pile casting 3 and steel reinforcement cage 4 are suspended in the positioning tube 2 at stake holes aperture simultaneously by positioning pluging rod 7,
Form the positioning integrated with steel reinforcement cage 4 of permanent steel pile casting 3.
The utility model transferred by pull positioning pluging rod 7 with fixed steel bars cage 4 and permanent steel pile casting 3, it is easy to operate,
Reduce when permanent steel pile casting 3 is transferred with interfering with each other in 4 decentralization process of steel reinforcement cage, reduces docking, the decentralization of steel reinforcement cage 4
Time, while reducing the quantity of construction personnel, it greatly improves work efficiency, ensure that construction quality.
