Description
Technical field
The utility model relates to building technical fields, in particular relate to deep footing groove enclosing structure, in particular to a kind of double
Stake combines the supporting construction of wide-angle anchor cable.
Background technique
Currently, especially northern, the most commonly used is pile-anchor retainings, single in the Deep Foundation Pit Supporting Engineering of vertical cut
Campshed adds a layer anchor pole, the retaining design following points limitation or defect:
1, since city surrounding building underground is built, structures influence, horizontal rock-bolt length is too long to construct, Single row pillars
The case where anchor structure cannot achieve is relatively common；
2, the stratum of rich groundwater, anchor bolt construction destroy construction curtain, cause soil erosion on the outside of foundation pit, construction finishes
Rear wall anchor hole largely seeps water, and foundation pit periphery differential settlement is caused when serious；
3, the anchor pole number of plies is more, and stage excavation construction anchor pole is long in time limit, needs earth excavation close fit, and deep basal pit needs to turn
A ramp is changed, causes foundation pit long in time limit, earthwork cooperation is costly.
And under the environmental condition for can not achieve multiple-layer horizontal anchor pole, also there is the supporting patented technology of many double-row piles.
But it is looked into, the double-row pile patented technology having disclosed, entirely cantilever earth-retaining, stake top does not have the operative constraint of horizontal force,
Foundation pit displacement is relatively large, and stringent to deformation requirements for surrounding enviroment cannot meet the requirements；In addition to stake top between double-row pile
Except, most technologies do not connect effectively, and pile body local pressure is big, cause a diameter and arrangement of reinforcement larger, cost is higher.
Wherein, associated patented technology, an entitled " double-row pile composite construction and its construction party for deep basal pit supporting and retaining system
The patent application of method " (application No. is 201810123369.X), discloses double -- rowed pipe pile supporting, and heel row tubular pole vertically sets pre- answer
Power anchor cable, the main function of the vertical anchor cable are the resistance to capsizings for increasing supporting construction, substantially or cantilever soil-baffling structure.
Entitled " double-row pile combines Deep Foundation Pit Support for Soft Soil structure and construction method with diagonal brace " (application No. is
201610516496.7) patent application discloses that a kind of double-row pile combines Deep Foundation Pit Support for Soft Soil structure with diagonal brace, in base
Soil layer is consolidated along the inside of interior campshed setting hole prime cement in hole bottom；Diagonal brace is set between interior campshed and Base isolation system, diagonal brace across
The middle vertical steel lattice column of setting；Waist rail is arranged with interior campshed joint in diagonal brace and Base isolation system joint setting bottom support pier.
Diagonal brace is set after foundation pit inner excavation a part, needs to excavate close fit, complex process, the duration is longer.
The hair of entitled " a kind of drag-line double-row pile (wall) supporting construction " (application No. is 201510294044.4)
Bright application discloses that a kind of front-seat support pile elevates above the soil to form Suo Zhu, heel row support pile plane earth, Suo Zhuyu heel row supporting
It is provided between stake to prestressed cable, which belongs to the connection structure between two campsheds, complex process, wherein below earth's surface
Drag-line be difficult to realize, it is many that preceding campshed is higher by earth's surface, influences live civil construction, cost is higher.
One entitled " Double-row-piles Structure that a kind of pile body is equipped with concrete-cored horizontal jet grouting stake " (application No. is
201410847109.9) patent of invention discloses on the basis of Retaining Structure with Double-row Piles, the horizontal concrete-cored rotation of construction in layer
Stake is sprayed, reinforcing body is prefabricated pile, and construction and excavation process is similar to multilayer suspension roof support, needs a cubic metre of earth close fit, need to convert
Ramp, long in time limit, cost is higher.
Entitled " a kind of Retaining Structure with Double-row Piles " (application No. is 201510635259.8), is by existing again after pile
Pile body drilling installation fashioned iron and slip casting, front and back campshed are attached, so that the whole lateral rigidity of double-row pile has obtained greatly
Promotion, first this method can destroy the most important some main reinforcements of pile body, seriously affect safety of structure；On the other hand,
Since drilling will pass through armored concrete, soil layer, armored concrete, existing drilling technique is difficult to realize；Third, double-row pile it
Between linking beam arrangement be it is uniformly distributed, do not consider the loading characteristic of double support pile and accordingly arranged.
How foundation pit deformation effectively controlled using Retaining Structure with Double-row Piles, the space for occupying periphery is smaller, avoids side wall
A large amount of infiltrations become the Important Problems that those skilled in the art need to solve.
