Description
Technical field
The present invention relates to technical field of civil engineering, a kind of specifically inner supporting structure of pattern foundation pit supporting structure.
Background technique
The inner support of pattern foundation pit supporting structure mainly has horizontally-supported, oblique throwing to support two seed types, and common backing material is mixed for reinforcing bar
Solidifying soil and fashioned iron.Set at present is horizontally-supported, covers the excavation face of foundation pit, subsequent digging muck haulage and underground structure is caused to be applied
Work is inconvenient, increases the problems such as duration and cost.When foundation pit plane is larger, horizontally-supported cost is quite high, long construction period.
Then there is steel construction and tiltedly throw support structure, preferably solve the horizontally-supported existing above problem, but tiltedly throw support structure to be
It is supported on the bottom plate of underground structure, it is necessary to first stay native slope to excavate the bottom plate formation supporting-point for tiltedly throwing support bearing position, this
It needs to be arranged post-cast strip to underground structure bottom plate and generates waterproof problem.Key is that native region is stayed to be located at the lower section for tiltedly throwing support, at this
Digging muck haulage in a region will be very difficult, and increased duration and cost hinder the application of such kind of support construction.
Existing inner support technology there are aiming at the problem that, domestic pharmaceutical industry proposes some solutions, such as: patent application
Number it is 201711143352.2, proposes " a kind of combined type fashioned iron, slip casting steel pipe bearing diagonal foundation pit enclosure structure "；Patent application
Number be 201820137088.5, propose " a kind of steel pipe-shaped steel combination formula diagonal brace foundation pit supporting construction "；Number of patent application is
201810596971.5 proposing " a kind of foundation pit diagonal brace pile construction method and its auxiliary tool "；Number of patent application is
201310529197.3, it proposes " a kind of big foundation pit diagonal brace structure ", these patent applications are proposed using in the diagonal
Supporter is inserted into bottom of foundation ditch stratum, forms supporting-point, is formed and is infused in the slip casting from inside to outside of fashioned iron bearing diagonal by Grouting Pipe
Slurry generates the methods of supporting force to replace existing oblique throwing support to be supported on floor structure, to solve foundation pit support and the earthwork
The difference of the difficulty of construction, these patents is only that material specification used in bearing diagonal, combination and type of attachment not
Together, but through analysis there are the following problems:
1) reinforcing of the diagonal brace bearing soil body is realized by grouting method, the diffusion of slurries not can control, along diagonal brace direction
The consolidation effect of the periphery soil body is difficult to ensure, in soft soil foundation, the supporting force of needs can not be provided；
2) diagonal brace, taper pile or plumb pile and the contact area of foundation pit lower part weak soil are limited, and horizontal bearing capacity is low, and weak soil provides
Frictional resistance be unable to satisfy diagonal brace bearing requirement；
3) when needing biggish support force, diagonal brace increases horizontal supporting component, the length of diagonal brace by increasing inclination angle
It certainly will will lengthen, there is no column rest, stability will be unable to guarantee, the axial force of the supports provided will be greatly decreased；
4) when the length of diagonal brace is longer, biggish deformation will be generated by not applying prestressed supporting beam initial deformation,
Cause the larger displacement of foundation pit；
5) support force is improved by the length of the insertion hole following soil layer in bottom, not accounting for friction section is to have critical length
, it is more than critical length, support force can not improve.
Existing technology and patent, if improving supporting force by widened diagonal brace cross dimensions or lengthening insertion depth
Words, will lead to diagonal brace insertion constructional difficulties, and cost is excessively high.It can be said that these methods do not take the increase bottom of foundation ditch soil body to mention
The supporting force measure for supplying diagonal brace is difficult to the Deformation control requirement for meeting diagonal brace to pattern foundation pit supporting structure.
Therefore, engineering circles need to find effective diagonal brace bearing method, can overcome defect existing for current diagonal brace technology,
Cost can be reduced again, accelerates speed of application, protects the environment on foundation pit periphery, realize civilized construction.
Summary of the invention
Technical problem to be solved by the present invention lies in overcome irrationality, the construction matter of existing inclined support structure and stress
The deficiencies of amount is difficult to ensure and detects, deformation control of foundation pit effect is poor provides a kind of a kind of taper pile support of novel pattern foundation pit supporting structure
Structure and construction method, main innovation point are to manufacture the supporting mass of a major diameter by jet mixing method；Pass through increase
Blade improves frictional resistance；Supporting force is improved by reversed diagonal brace and controls the displacement of diagonal brace；By being arranged horizontally at hole bottom
Beam and reinforcement cushion constrain the horizontal displacement of diagonal brace.
In order to achieve the above objectives, this patent the technical solution adopted is that:
The taper pile support structure is the skewed horizontal load structure being set on the inside of foundation pit, it is by upper support cant beam and lower part
