Abstract
The invention discloses a double-row pile support structure which is composed of a front-row pile (1), a back-row pile (2), a front-row pile top beam (3), a back-row pile top beam (4), a pile top connecting beam (5) and pile body connecting beams (6), wherein between the front-row pile (1) and the back-row pile (2), a pile top is provided with the connecting beam, and a pile body is also provided with the connecting beams. According to the invention, the front-row pile (1) is reliably connected with the back-row pile (2) through the connecting beams, so that the integral lateral rigidity of the double-row pile structure is greatly improved. Meanwhile, because the construction of the structure has a relatively small range of influence to the environment, the influence to underground pipelines, ducts and the like of adjacent buildings can be reduced in the municipal engineering, so that the structure has the process characteristics of reliability, practicability, easy operation and the like.
Description
Technical field
The present invention relates to the pile body of a kind of Retaining Structure with Double-row Piles, particularly double-row pile.
Background technology
Along with expansion gradually and the development of contemporary project scale, traditional single antislide pile technology can not better meet the requirement of engineering sometimes, its basic reason is that single bank protection cantilever pile effect in control 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 that more can adapt to large-scale engineering, become support form conventional in base pit engineering, slope project.Traditional Retaining Structure with Double-row Piles normally arranges Guan Liang at front two rows stake pile body, and between the campshed of front and back, only arrange one space structures pushing up coupling beam and form similar door frame, and this can play the cooperative bearing effect of front and back campshed to a certain extent jointly.But, when some situation stake is long or geological condition change is comparatively complicated, because double-row pile only has one connection on stake top, make the change of the line of deflection between the campshed of front and back possible and inconsistent, this have impact on the bending resistance of double-row pile and overall lateral rigidity greatly.As the mode by adding anchor addresses this problem, then need to consider that anchor pole, anchor cable etc. affect problem to the underground pipeline, pipeline etc. of adjacent structure.Therefore, how under the prerequisite less on adjacent structure impact, being improved the overall lateral rigidity of double-row pile by corresponding strengthening measure, is the problem needing in civil engineering to consider.
Summary of the invention
The technical problem to be solved in the present invention: provide a kind of Retaining Structure with Double-row Piles, to solve when the unitary side of double-row pile is to insufficient rigidity, and employing adds underground pipeline, the underground utilities time institute problems faced that the measures such as anchor affect adjacent structure.
Technical solution of the present invention is: a kind of Retaining Structure with Double-row Piles, comprises front campshed and rear campshed, is provided with stake top linking beam, is 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 longitudinal direction is in being arranged in parallel, and transverse direction is rectangular to be arranged in juxtaposition.
For strengthening the globality between every campshed, front campshed, rear campshed all arrange Guan Liang on stake top.
Connect at stake very useful stake top linking beam between front campshed, rear campshed.
Improve its bending resistance and overall lateral rigidity for the cooperative bearing effect before and after playing between campshed, reliably connect with pile body linking beam between the pile body of row pile of front and back, the vertical distribute space of pile body linking beam is 1 ~ 3 meter, is arranged at above pile body part at the bottom of Foundation Pit.
Pile body linking beam steel used comprise reinforcing bar, rail or i iron.
The present invention forms a statically-indeterminate structure by linking beam between front campshed, rear campshed, front-seat dowel crown beam, rear campshed Guan Liang and multiple tracks stake, and this structure can make double-row pile better coordinate with stressed, substantially increases the overall lateral rigidity of double-row pile.Meanwhile, add compared with the methods such as anchor with traditional, this structure need not consider that construction affects problem to the pipeline, pipeline etc. of adjacent structure, and the influence basin of construction is less.To the slope body that some strict controlling distortion require, this structure also has fabulous applicability.
Accompanying drawing explanation
Fig. 1 is structural representation plan view of the present invention.
Fig. 2 is structural representation sectional drawing of the present invention.
Detailed description of the invention
See accompanying drawing 1 ~ accompanying drawing 2, the present invention is a kind of Retaining Structure with Double-row Piles arranging linking beam at pile body, comprises front campshed 1, rear campshed 2, front-seat dowel crown beam 3, rear campshed hat 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., wherein 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), transverse direction is rectangular to be arranged in juxtaposition (as shown in Figure 2, from cross-sectional direction, the rectangular frame-shaped of campshed 2 after a front campshed 1 and).The complete excavation namely carrying out hole stake of pile layout, hole stake is hand excavated pile or mechanical hole building stake, and construction and excavation process must by related specifications strict implement.After hole stake excavation, lay reinforcing cage and fluid concrete and maintenance.Reinforcing cage must reserve the position of pile body linking beam 6 when colligation, so that the construction in later stage and operation, 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 the sectional dimension of front-seat dowel crown beam 3, rear campshed hat beam 4, stake top linking beam 5, arrangement of reinforcement and connection 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, aperture, and boring controlling depth is to be advisable slightly above the pile center of rear campshed.Complete pile body connecting material of putting into of holing also uses the slip casting of M30 cement mortar, and connecting material can use reinforcing bar, rail or i iron etc., and its length is that the centre distance between the campshed of front and back is long.
