Description
Technical field
The present invention relates to landslide, Slope Prevention and Base hole supporting technology field, be specifically related to a kind of Hoop-type circular-section anchor-rod slide-resistant pile and construction method thereof.
Background technology
Because antislide pile pile body adopts reinforced concrete structure, pile body stiffness is large, self-stability can be high, can resist larger Thrust of Landslide, start to be widely used in landslide control engineering in the sixties in last century.Antislide pile pile body part build-in is below slide plane, the counter-force provided by the following good ground of slide plane resists gliding mass thrust, this lower end is fixed, upper end freely beam type force modes makes the pile body cross section of antislide pile larger, embed pile body needed for good ground longer, construction material expends more.The appearance of anchor pole antislide pile successfully solves this problem, can the anchor pole of Shi Hanzhang or anchor cable by arranging in stake top section, antislide pile stress system becomes that lower end is fixed, upper end thereof, there will not be when making antislide pile resist gliding mass thrust on rear side of only pile body by curved situation, but simultaneously by moment of flexure before and after antislide pile stake, reduce Internal forces, give full play to the resistance to tension of anchor pole and the bending resistance of antislide pile, reach the object reducing pile body sectional dimension and antislide pile fixed section length.
Antislide pile section form mainly contains rectangle and circle shape, retailing piles with round section structure is well-balanced, mechanical hole building is convenient, is not only widely used in the indefinite complicated landslide control of main sliding direction of landslide, in the pattern foundation pit supporting structure being simultaneously also widely used in being applicable to mechanical hole building and high side slope engineering.Traditional doughnut draws antislide pile generally to adopt reserved bolthole or location rig directly from the construction method that pile body creeps into, be difficult to guarantee that anchor pole projection line is accurately arranged on the axis of symmetry of circular cross-section, thus cause the stressed and different design of actual pile body, the bending resistance of pile body can not be given full play to like this, pile body is also made to be subject to torsional interaction, do not reach the expection supporting effect of circular anchor pole antislide pile, and there is certain potential safety hazard.Therefore, a kind of novel circular section anchor pole antislide pile is invented significant for complexity landslide, high gradient slope improvement and deep foundation pit support.
Summary of the invention
The present invention seeks to the structural advantage in conjunction with anchor pole antislide pile force modes and circular cross-section antislide pile, to solve the connection of anchor pole and retailing piles with round section for cutting point, propose that a kind of structure is simple, with low cost, the Hoop-type circular-section anchor-rod slide-resistant pile of easy construction and construction method thereof.
A kind of Hoop-type circular-section anchor-rod slide-resistant pile of the present invention, comprising: retailing piles with round section, anchor ear type steel band, steel nail, anchor pole, ground tackle and shotcrete with wire mesh layer; On retailing piles with round section, cambered surface hoop has anchor ear type steel band, anchor pole connects anchoring through the anchor pole preformed hole on anchor ear type steel band straightway, and outside steel band straightway, coordinate anchor pole incident angle that oblique holder is set, ground tackle and billet is set between tiltedly holding in the palm, concrete sealing off and covering anchorage is arranged in tiltedly holder, outside anchor ear type steel band band, hang with shotcrete with wire mesh layer, steel nail inserts in the steel nail preformed hole on shotcrete with wire mesh layer, anchor ear type steel band and retailing piles with round section.
A kind of Hoop-type circular-section anchor-rod slide-resistant pile construction method of the present invention, concrete technical scheme is as follows:
1. retailing piles with round section is squeezed in sliding bed through gliding mass and slide strips;
2. in the outside cambered surface of retailing piles with round section, hoop has anchor ear type steel band;
3. steel nail inserts the steel nail preformed hole of pile body, anchor ear type steel band after smearing anchoring adhesive;
4. at precalculated position boring, placement anchor pole, anchor pole is squeezed into sliding bed and slip casting through gliding mass and slide strips;
5. ground tackle is utilized to be fixed on retailing piles with round section by anchor ear type steel band;
6. outside anchor ear type steel band straightway, coordinate anchor pole incident angle that oblique holder is set;
7. ground tackle and arrange billet between tiltedly holding in the palm, then encapsulates ground tackle and billet with concrete;
8. the last side extension contrary with retailing piles with round section at anchor ear type steel band carries out shotcrete with wire mesh.
Described retailing piles with round section is reinforced concrete structure, radially equidistant placement 3 ~ 8 steel nail preformed holes outside antislide pile pile body upper end.
Described anchor ear type steel band adopts steel plate compressing, and middle part arc section is semicircle, and internal diameter is consistent with retailing piles with round section diameter, and two ends straightway is vertical with half rounded head tangent line; Arc section equidistant placement five steel nail preformed holes, overlap with the steel nail preformed hole position on retailing piles with round section, both sides straightway respectively arranges an anchor pole preformed hole.
The technological merit of Hoop-type circular-section anchor-rod slide-resistant pile of the present invention is as follows:
(1) the present invention is in conjunction with the structural advantage of anchor pole antislide pile force modes and circular cross-section antislide pile, the effect counter-force of anchor pole is converted into radial pressure to pile body by anchor ear type, utilize the stronger anti-pressure ability of reinforced concrete structure, its resultant direction is overlapped with stake cross section axis of symmetry, the bending resistance of antislide pile and the resistance to tension of anchor pole are given full play to, avoid anchor bolt construction and destroy antislide pile pile body structure, prevent anchor pole antislide pile in use by torsional interaction.
(2) the present invention saves pile shaft material, is convenient to mechanical piling, is applicable to complicated landslide, high side slope and Deep Foundation Pit Supporting Project.
(3) anchor ear connecting portion of the present invention is easy to maintenance, only need chisel shotcrete with wire mesh layer if desired, and removing ground tackle can change the parts such as steel band, steel nail.
