Abstract
The utility model discloses a kind of Retaining Structure with Double-row Piles, supporting construction is made up of front campshed (1), rear campshed (2), front-seat dowel crown beam (3), heel row dowel crown beam (4), stake top linking beam (5) and pile body linking beam (6), between forward and backward campshed (1), (2) in addition to linking beam is set on stake top, also linking beam is set at pile body.This utility model is due to being reliably connected of linking beam between forward and backward campshed (1), (2) so that the overall lateral rigidity of double-row pile has obtained great lifting.Simultaneously as the coverage of the Construction on Environment of this structure is less, municipal works decrease the problem that affects of the underground piping on close to buildings, pipeline etc., therefore there is the process characteristics such as the most applicable, easily operated.
Description
Technical field
This utility model relates to the pile body of a kind of Retaining Structure with Double-row Piles, particularly double-row pile.
Background technology
Gradually expansion and development along with project scale in the present age, traditional single friction pile technology can not better meet the requirement of engineering the most, its basic reason is that single bank protection cantilever pile effect in terms of controlling Horizontal Displacement is not satisfactory, is especially more restricted in the engineer applied stricter to Pull-out test.And Retaining Structure with Double-row Piles is as a kind of retaining structure being suitable for large-scale engineering, become support form conventional in base pit engineering, slope project.Traditional Retaining Structure with Double-row Piles is typically to arrange Guan Liang at front two rows stake pile body, and only arranges one space structure pushing up the similar door frame of coupling beam composition between campshed front and back, and this can play the cooperative bearing effect of before and after campshed to a certain extent jointly.But, when some situation stake is long or geological condition change is complex, owing to double-row pile only has one connection on stake top so that front and back the line of deflection change between campshed may be not consistent, this bending resistance leveraging double-row pile and overall lateral rigidity.As solved this problem by the way of adding anchor, then need to consider that anchor pole, anchor cable etc. affect problem to the underground piping of close to buildings, pipeline etc..Therefore, how on the premise of less on close to buildings impact, improved the overall lateral rigidity of double-row pile by corresponding strengthening measure, be the problem needing in civil engineering to consider.
Summary of the invention
The technical problems to be solved in the utility model: provide a kind of Retaining Structure with Double-row Piles, to solve the overall lateral insufficient rigidity when double-row pile, and uses and adds problem encountered when the measures such as anchor affect the underground piping of close to buildings, underground utilities.
Technical solutions of the utility model are: a kind of Retaining Structure with Double-row Piles, including front campshed and rear campshed, be provided with stake top linking beam, be provided with pile body linking beam between the pile body of forward and backward campshed between the stake top of forward and backward campshed.
Front campshed, rear campshed, longitudinally in being arranged in parallel, the most rectangular are arranged in juxtaposition.
For strengthening the globality between every campshed, front campshed, rear campshed are respectively provided with Guan Liang on stake top.
Connect at stake very useful stake top linking beam between front campshed, rear campshed.
For cooperative bearing effect between campshed before and after playing and improve its bending resistance and overall lateral rigidity, it is reliably connected with pile body linking beam between pile body of row pile front and back, the vertical distribution spacing of pile body linking beam is 1～3 meter, is arranged at above pile body part at the bottom of Foundation Pit.
Steel used by pile body linking beam include reinforcing bar, rail or I-steel.
This utility model forms a redundant structure by linking beam between front campshed, rear campshed, front-seat dowel crown beam, heel row dowel crown beam and multiple tracks stake, and this structure can make double-row pile preferably coordinate and stress, substantially increases the overall lateral rigidity of double-row pile.Meanwhile, with traditional add the methods such as anchor compared with, this structure need not consider the to construct pipeline on close to buildings, pipeline etc. affects problem, and the coverage of construction is less.Slope body to some strict control deformation requirements, this structure also has the fabulous suitability.

Detailed description of the invention
Seeing accompanying drawing 1～accompanying drawing 2, this utility model is a kind of Retaining Structure with Double-row Piles arranging linking beam at pile body, including front campshed 1, rear campshed 2, front-seat dowel crown beam 3, heel row dowel crown beam 4, stake top linking beam 5 and pile body linking beam 6.
The stake position of double-row pile is arranged according to design pile-type, stake footpath and pilespacing etc., the most front campshed 1, rear campshed 2 are longitudinally in being arranged in parallel (as shown in Figure 1, campshed 2 after the corresponding a line of campshed 1 before a line), the most rectangular it is arranged in juxtaposition (as shown in Figure 2, in terms of cross-sectional direction, the rectangular frame-shaped of campshed 2 after a front campshed 1 and).The complete excavation i.e. carrying out hole stake of pile layout, hole stake is artificial digging pile or mechanical hole building stake, and construction and excavation process must be by related specifications strict implement.After hole stake excavation, lay steel reinforcement cage and pour into a mould concrete and maintenance.Steel reinforcement cage must reserve the position of pile body linking beam 6 when colligation, in order to the construction in later stage and operation, and the vertical interval of pile body linking beam 6 is 1～3 meter, and pile body linking beam 6 is arranged at above pile body part at the bottom of Foundation Pit.
Determine front-seat dowel crown beam 3, heel row dowel crown beam 4, sectional dimension, arrangement of reinforcement and the connection of stake top linking beam 5 and construct.
Be drilled with the connecting hole of pile body linking beam 6 from foundation ditch side, boring direction is level, 130 millimeters～150 millimeters of aperture, and boring controlling depth is advisable with the pile center slightly above rear campshed.Holing and complete put into pile body connecting material and with M30 cement mortar slip casting, connecting material can use reinforcing bar, rail or I-steel etc., and before and after it is a length of, the centre distance between campshed is long.
