Description
Technical field
The present invention relates to a kind of piling strtucture, a kind of piling strtucture of umbrella, belongs to building structure technology field specifically.
Background technology
At present, in order to keep, city is unimpeded arranges street lighting and traffic guide facility to town road.These facility height can reach 10 ~ 20 meters, belong to that vertical load is relatively little, horizontal loading produce the larger structure of moment of flexure, resistance to capsizing requires that the wind loads such as high, especially coastal, mountain area are particularly evident compared with large regions.
At present, these general employing cast-in-situ steel reinforced concrete single footings, facility basis, for meeting overturning or slip resistance analysis requirement basis pedestal foot general buried depth at 3 ~ 4 meters not etc., conventional form of construction work is anti-excavation construction after road surface structure is basically completed, and carries out building of pattern foundation pit supporting structure and reinforced concrete independent foundation.This form of construction work not only long construction period, excavation supporting costly and road repeatedly excavate and cause road structure to destroy.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide that a kind of structure is simple, easy construction, the duration is short, cost the is low piling strtucture of falling umbrella.
According to technical scheme provided by the invention, a kind of piling strtucture of falling umbrella comprises pile body main body and web frame, it is characterized in that: pile body main body is hollow spike-like structures, comprise pile cover, stake bar and pile crown, pile cover, stake bar and pile crown are in turn connected into one from top to bottom, be provided with several Grouting Pipe in pile body main body, the sidewall of stake bar is provided with the through propelling groove in left and right; Web frame is for falling umbrella-shaped structure, comprise movable geosynclinal block, quarter butt, stock, fixing geosynclinal block and advance frame, fixing geosynclinal block is fixed on a bar bottom, advance frame is connected inside movable geosynclinal block, advance frame is slidably mounted on and advances in groove, the hinged multiple quarter butt of movable geosynclinal block external surface, multiple quarter butt is along the circumferential direction uniformly distributed, the hinged corresponding stock arranged in lower end of each quarter butt, the fixing hinged multiple stock arranged with quarter butt one_to_one corresponding of geosynclinal block external surface, multiple stock is along the circumferential direction uniformly distributed.
Further, pile crown is pyramidal structure, and the cross section of pile crown diminishes from top to bottom gradually.
Further, stake bar is hollow rod shape structure.
Further, pile cover is provided with several bolts of appearing.
Further, movable geosynclinal block is hollow annular structure.
Compared with the prior art the present invention has the following advantages:
Existing monolithic reinforced concrete structure is optimized to the prefabricated piling strtucture of falling umbrella by the present invention, can modularized production, without the need to concrete curing, can greatly reduce construction period and ensure product quality; Because piling and slip casting all complete by small-sized movable engineering apparatus, piling, grouting equipment convenient transportation, take up room little, mechanization can implement, greatly reduces difficulty of construction and operating expenses.Importantly do not need excavation present situation pavement of road to carry out concreting, do not need the measures such as excavation, supporting, reduce engineering cost and be convenient to safe construction.

Description of reference numerals: 1-pile cover, 2-stake bar, 3-pile crown, 4-advance groove, 5-Grouting Pipe, 6-appear bolt, the movable geosynclinal block of 7-, 8-quarter butt, 9-stock, 10-fix geosynclinal block, 11-advance frame.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises pile body main body and web frame, and pile body main body is hollow spike-like structures, comprises pile cover 1, stake bar 2 and pile crown 3, and pile cover 1, stake bar 2 and pile crown 3 are in turn connected into one from top to bottom.
Be provided with several Grouting Pipe 5 in pile body main body, grouting equipment is by Grouting Pipe 5 to the slip casting of web frame surrounding soil, and these slip castings basis of formation together with web frame amplifies pin, guarantees structure foundation bearing capacity and resistance to capsizing.
Described pile crown 3 is pyramidal structure, and the cross section of pile crown 3 diminishes from top to bottom gradually, and pile crown 3 is more easily driven underground, and during construction, ringing engine can be adopted to construct.
Described stake bar 2 is hollow rod shape structure, and the sidewall of stake bar 2 is provided with the through propelling groove 4 in left and right, advances in groove 4 for installing advance frame 11.
Described pile cover 1 is as the erection support of means of transportation, and pile cover 1 is provided with several bolts 6 of appearing, and by appearing, bolt 6 connects external equipment.
Web frame is for falling umbrella-shaped structure, comprise movable geosynclinal block 7, quarter butt 8, stock 9, fixing geosynclinal block 10 and advance frame 11, fixing geosynclinal block 10 is fixed on a bar 2 bottom, and movable geosynclinal block 7 is hollow annular structure, inner side connects advance frame 11, and advance frame 11 is slidably mounted on and advances in groove 4.The hinged multiple quarter butt 8 of movable geosynclinal block 7 external surface, multiple quarter butt 8 is along the circumferential direction uniformly distributed.The hinged corresponding stock 9 arranged in lower end of each quarter butt 8.The fixing hinged multiple stock 9 arranged with quarter butt 8 one_to_one corresponding of geosynclinal block 10 external surface, multiple stock 9 is along the circumferential direction uniformly distributed.
