Description
Technical field
It the utility model is related to a kind of foundation structure, more particularly to a kind of street lamp and traffic sign foundation structure.
Background technology
At present, town road is in order to keep the city traffic capacity typically to set street lighting and traffic to guide facility.These
Street lamp and traffic guiding facility height up to 10 ~ 20 meters, belong to vertical load is relatively small, moment of flexure produced by horizontal loading compared with
Big structure, resistance to capsizing require high.
These street lamps and traffic sign facility basis typically use cast-in-situ steel reinforced concrete isolated footing at present, anti-to meet
Topple requirement, basic pedestal foot is set in foundation bottom, for general buried depth at 3 ~ 4 meters, conventional form of construction work is in road
After pavement structure is basically completed, carries out counter excavate of pattern foundation pit supporting structure and carry out pouring for armored concrete.This mode is not only constructed week
Phase is long, excavation supporting is costly and road excavates and causes pavement structure to destroy repeatedly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of street lamp and traffic sign foundation structure, is utilizing the road
Lamp and traffic sign foundation structure solve that foundation structure resistance to capsizing is poor, structural stability is not high and the easy leakage conductance of street lamp causes
The problem of security incident.
In order to solve the above-mentioned technical problem, street lamp and traffic sign foundation structure of the present utility model include precast pile,
The prefabricated pile crown being connected with pile body lower end, precast pile outer sheath are provided with cannulated sleeve, and cannulated sleeve upper end is provided with several fillings
Hole is starched, cannulated sleeve is connected by several cross bars being uniformly arranged with precast pile, and every cross bar each extends to cannulated sleeve
Outside, precast pile upper end mounting flange, pre-buried two Grouting Pipes in precast pile, Grouting Pipe upper end on ring flange with holding level with both hands
Together, Grouting Pipe lower end is stretched into prefabricated pile crown and extends to prefabricated pile head side-wall outer side, pre-buried some lower margins in precast pile
Bolt, the lower end of foundation bolt are embedded to inside precast pile, and ring flange, prefabricated pile crown bottom connection are stretched out in the top of foundation bolt
Earth brace.
The length that the cross bar is extended on the outside of cannulated sleeve is 20cm.
The foundation bolt radical is 4.
The prefabricated pile crown is tapered.
The a diameter of 50cm of precast pile.
Using this street lamp and traffic sign foundation structure, there is advantages below：
1st, existing monolithic reinforced concrete structure is optimized to precast reinforced concrete pile by the utility model, it is not necessary to is opened
Dig present situation pavement of road, simple in construction, convenient for installation and maintenance and construction is simple, it is not necessary to the measure such as excavation supporting, can machinery
Change and implement, substantially reduce construction period and operating expenses.
2nd, because precast pile outer sheath is provided with cannulated sleeve, cannulated sleeve upper end is provided with several grout holes, hollow sleeve
Cylinder is connected by several cross bars being uniformly arranged with precast pile, pre-buried two Grouting Pipes, Grouting Pipe upper end in precast pile
Concordant with ring flange upper end, Grouting Pipe lower end is stretched into prefabricated pile crown and extends to prefabricated pile head side-wall outer side, by hollow
Resistance to plucking and overturn-preventing performance are strengthened in sleeve and in the slip casting of prefabricated pile crown both sides, is each extended to by cross bar outside cannulated sleeve
Side, so add mass-type foundation structure and the snap-in force of ground.
3rd, because prefabricated pile crown bottom connects earth brace, it can so prevent street lamp electric leakage from causing the generation of security incident.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is schematic diagram of the present utility model.
Wherein have：1. precast pile；2. prefabricated pile crown；3. cannulated sleeve；4. cross bar；5. grout hole；6. lower margin
Bolt；7. Grouting Pipe；8. ring flange；9. earth brace.
Embodiment
The prefabricated pile crown that street lamp shown in Fig. 1 and traffic sign foundation structure include precast pile, is connected with pile body lower end, in advance
Pile body outer sheath processed is provided with cannulated sleeve, cannulated sleeve upper end is provided with several grout holes, and cannulated sleeve is by being uniformly arranged
Several cross bars are connected with precast pile, and every cross bar is each extended on the outside of cannulated sleeve, precast pile upper end mounting flange,
Pre-buried two Grouting Pipes in precast pile, Grouting Pipe upper end is concordant with ring flange upper end, and Grouting Pipe lower end is stretched into prefabricated pile crown
And extend to prefabricated pile head side-wall outer side, pre-buried some foundation bolts in precast pile, foundation bolt lower end embedment it is prefabricated
Inside pile body, ring flange is stretched out on the top of foundation bolt, and prefabricated pile crown bottom connects earth brace.
The length that the cross bar is extended on the outside of cannulated sleeve is 20cm.
The foundation bolt radical is 4.
The prefabricated pile crown is tapered.
The a diameter of 50cm of precast pile.
Mass-type foundation structure is squeezed into ground during implementation, then the grout hole in cannulated sleeve upper end and Grouting Pipe upper end
Grouting.Existing monolithic reinforced concrete structure is optimized to precast reinforced concrete pile by the utility model, it is not necessary to is excavated existing
Shape pavement of road, simple in construction, convenient for installation and maintenance and construction is simple, it is not necessary to the measure such as excavation supporting, can mechanization reality
Apply, substantially reduce construction period and operating expenses.Because precast pile outer sheath is provided with cannulated sleeve, cannulated sleeve upper end is provided with
Several grout holes, cannulated sleeve are connected by several cross bars being uniformly arranged with precast pile, pre-buried two in precast pile
Root Grouting Pipe, Grouting Pipe upper end is concordant with ring flange upper end, and Grouting Pipe lower end is stretched into prefabricated pile crown and extends to prefabricated pile crown
Side-wall outer side, by strengthening resistance to plucking and overturn-preventing performance in cannulated sleeve and in the slip casting of prefabricated pile crown both sides, pass through cross bar
Each extend on the outside of cannulated sleeve, so add mass-type foundation structure and the snap-in force of ground.Because prefabricated pile crown bottom connects
Earth brace is connect, can so prevent street lamp electric leakage from causing the generation of security incident.
The technical characteristic for not having to describe in detail in the application is prior art.Above-described embodiment only illustrative the application
Principle and its effect, not for limitation the application.Any person skilled in the art all can be in the essence without prejudice to the application
