Description

A kind of driver-extractor reclaiming for steel pipe fender post
Technical field
This utility model is related to fender post technical field of construction and in particular to a kind of pull out for rising of steel pipe fender post recovery Device, is primarily adapted for use in subway station steel pipe fender post and reclaims.
Background technology
With the quickening of Urbanization Process In China, urban population increases day by day substantially to be changed to the pressure that traffic brings.Thus Traditionally going up the corresponding underground traffic of traffic with us just becomes the new channel alleviating urban traffic pressure.Here it is it is current The subway transportation that city big or middle is strongly being developed.How foundation ditch protection is carried out using fender post in subway station is built, and enclose The cost at station about 15% ~ 20% shared by fender pile structure.And in subway station sets, supporting pile structure is usually temporary structure, Discard after construction when station, and supporting pile structure can not have enough to meet the need reuse, lead to station construction relatively costly.
This traditional supporting pile structure is constructed and is primarily present following deficiency:
1st, supporting pile structure can not reuse, and construction cost is high;
2nd, supporting pile structure working procedure is many, and the construction period is longer;
3rd, the road occupying of fender post pile driving construction, occupation of land are more.
Utility model content
For avoiding the weak point existing for above-mentioned prior art, this utility model provides one kind can improve and goes along with sb. to guard him pile driving construction Operation, with reduction of erection time and reduces cost, and improves the driver-extractor that fender post has enough to meet the need utilization ratio.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of driver-extractor reclaiming for steel pipe fender post, includes driver-extractor pedestal, auxiliary on this driver-extractor pedestal Help hanging apparatus and the anchor ear device for buckle steel pipe fender post, wherein between anchor ear device and driver-extractor pedestal, pass through thousand Jin top connects.
Described auxiliary hoisting device includes gate frame and the jack calabash that can be moved horizontally along this gate frame.
Described anchor ear device includes two semicircular circumferential band, very heavy with described at least provided with one in this circumferential band Push up the jacking block using cooperatively.
From above technical scheme, this utility model has carried out pulling out operation using assembled structure, has substantially increased Pull out working performance, reduce operation easier, save cost.

Specific embodiment
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As shown in Figure 1,2 and 3, described driver-extractor includes driver-extractor pedestal 10, auxiliary hoisting device 20, anchor ear device 30 and Four jack 40, wherein auxiliary hoisting device are located above driver-extractor pedestal, and for lifting anchor ear device, described jack sets It is placed between driver-extractor pedestal and anchor ear device, for loading anchor ear device, this anchor ear device is used for buckle steel pipe fender post 50.
Described driver-extractor pedestal 10 is welded by 8 H type steel, and for supporting auxiliary hoisting device 20, this auxiliary lifts Device 20 includes gate frame 21 and jack calabash 22, and this gate frame is formed by steel-pipe welding, and driver-extractor pedestal h is inserted in bottom The hole that section steel flange is reserved, tightens nut anchoring up and down, and described jack calabash can be carried out along the entablature of gate frame Move horizontally, install for anchor ear device is carried out with lifting.
Described anchor ear device 30 includes two semicircle circumferential band being snapped on steel pipe fender post, steel pipe fender post local Wall thickness reduces, and to inside contracting, reserves the space being available for buckle, and two circumferential band wedge the retracted position in steel pipe fender post respectively, It is merged into a full circle, the connecting sewing position of two circumferential band carries out bolt connection by prepared screw-bolt hole.On anchor ear device altogether If 4 jacking blocks, apply pulling force for jack.
Described jack 40 adopts 150t hydraulic jack, and the present embodiment is entered to anchor ear device using four groups of hydraulic jack Row is adjusted, and quadrangularly is arranged between driver-extractor pedestal and anchor ear device.
Share pulling force by four jack, high degree avoid steel pipe fender post rise pull out during indivedual directions stress Excessive lead to top be subject to curved, produce diastrophic possibility, improve the safety pulling out operation.
In conjunction with accompanying drawing 4-7, the concrete construction method that steel pipe fender post is reclaimed is described:
Step one, smooth location, lay driver-extractor steel plate basis 60, dispose driver-extractor pedestal 10, with reference to Fig. 4;
Step 2, the H type steel edge of a wing of driver-extractor pedestal are provided with hole, the gate frame 21 bottom insertion of auxiliary hoisting device Wherein, tighten nut, anchor gate frame up and down, thereafter jack calabash 22 is arranged on gate frame, with reference to Fig. 5;
Step 3, two circumferential band 31 of anchor ear device are wedged respectively the retracted position of steel pipe fender post 50, be merged into Full circle is buckled on steel pipe fender post, tightens link position bolt, with reference to Fig. 6;
Step 4, installation jack 40, load and set the 40% of pulling force, check that each part whether there is problem, as existed Problem, need to stop loading, continue to pull out operation after Resolving probiems, with reference to Fig. 7;
Step 5, set within pulling force by setting 60%, 80%, 100% being loaded of pulling force, press 110% in addition, 120% is loaded, and every one-level holds lotus 1 minute, during as steel pipe fender post occur substantially loosen, then stop load;As loaded To setting the 120% of pulling force, steel pipe fender post occurs substantially loosening not yet, then stop loading, analyze reason, wait to find the cause And repeat step five after solving, with reference to Fig. 7;
Step 6, remove driver-extractor, using crane, steel pipe fender post is extracted;
Step 7, repeat step one to six, until complete rising of all steel pipe fender posts to pull out operation.
The steel pipe fender post that this utility model is used, after the completion of Foundation Pit Construction, can adopt vibration pipe-drawing equipment Extract from the soil body, the steel pipe fender post extracted can put back into again, to reach reusable purpose.Using can week Turn reusable supporting pile structure, construction cost can be substantially reduced and economize on resources the enhancing competitiveness in subway market for the enterprise, And working procedure can be reduced and save the duration, employing simultaneously can be had enough to meet the need without assembling reinforcement during reusable steel construction, in city Construction land tenure can be reduced as far as possible in city's construction.
The above embodiment is only preferred implementation of the present utility model to be described, not to this practicality New scope is defined, and on the premise of setting spirit without departing from this utility model, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the guarantor that claims of the present utility model determine In the range of shield.
