Abstract
The utility model discloses a kind of deep foundation pit steel tube/concrete and be combined inner supporting structure, being characterized in that the inner supporting structure of this deep basal pit is tiltedly thrown support by the concrete support being arranged on steel column with steel and formed, described concrete support is arranged on steel column and two ends are fixing with the waist rail of fender post is connected；What described steel tiltedly threw support one end and fender post encloses that purlin is fixing to be connected, and the other end is fixed with the bracket in Horizontal concrete support and is connected.It is good that this utility model compared with prior art has structural stability, excavation deformation and hole end resilience are little, the advantage that construction speed is fast, and soil excavation is convenient, advantage little to surrounding environment influence, work efficiency is high, especially bracing members can recycle after removing, and saves cost, and engineering cost is low, preferably resolve the cost height that deep pit digging uses multiple tracks concrete support to bring, the problems such as the duration is longer.
Description
Technical field
This utility model relates to deep footing groove enclosing structure technical field, and especially a kind of deep foundation pit steel tube/concrete is combined
Inner supporting structure.
Background technology
Currently, the comprehensive exploitation of Underground Space Resource becomes the important channel of city Sustainable Development, the many employings of excavation of foundation pit
Having support excavation to combine with building enclosure, pattern foundation pit supporting structure form is varied.
The deep basal pit of prior art the most all uses bracing members or concrete horizontal to support, and building enclosure has cast-in-situ bored pile
Campshed, diaphram wall, cement-soil-stirred pile method for strengthening etc., substantial amounts of concrete support structure adds making of pattern foundation pit supporting structure
Valency, and per pass concrete can excavate lower floor's earthwork after needing to reach prescribed strength, will be by concrete support after having excavated
Dismantling, cause the wasting of resources, the construction period is longer, concrete support dismounting difficulty, generally uses cutting mode to become after removing
Building waste abandons, and is also unfavorable for the sustainable development in city while ample resources has been lost.
Utility model content
The purpose of this utility model is that a kind of deep foundation pit steel tube/concrete designed for the deficiencies in the prior art is combined
Inner supporting structure, uses concrete horizontal to support and throws, with steel, the inner supporting structure that support combines, alleviate support system deadweight, stability
Good, soil excavation is convenient, and excavation deformation and hole end resilience are little, and work efficiency is high, and project progress is fast, and especially bracing members can after removing
With recycling, saving cost, engineering cost is low, preferably resolves deep pit digging and uses making of bringing of multiple tracks concrete support
Valency is high, removes difficulty, the problems such as the duration is longer.
The purpose of this utility model is achieved in that a kind of deep foundation pit steel tube/concrete is combined inner supporting structure, including
It is arranged on the fender post of foundation ditch periphery and is arranged on the waist rail enclosing purlin and middle part at fender post top, being characterized in this deep basal pit
Inner supporting structure tiltedly thrown support by the concrete support being arranged on steel column with steel and form, described concrete support is for being provided with cattle
The horizontal support elements of lower limb, concrete support is arranged on steel column and two ends are fixing with the waist rail of fender post respectively is connected；Institute
State steel and tiltedly throw support for the steel beam column of oblique pull, its one end and fender post enclose that purlin is fixing to be connected, the other end and Horizontal concrete support
On bracket fixing connect.
Described enclose to be equipped with on purlin, waist rail and bracket with steel tiltedly throw support and concrete support fixes the built-in fitting being connected.
Described steel column is arranged under the bracket of concrete support.
It is good that this utility model compared with prior art has structural stability, excavation deformation and hole end resilience little, construct into
Spending fast advantage, and soil excavation is convenient, advantage little to surrounding environment influence, work efficiency is high, after especially bracing members is removed
Can recycle, save cost, engineering cost is low, preferably resolves deep pit digging and uses multiple tracks concrete support to bring
Cost is high, removes difficulty, the problems such as the duration is longer.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2～Fig. 3 is that this utility model specifically uses schematic diagram.
Detailed description of the invention
Refering to accompanying drawing 1, this utility model is by being arranged on the waist rail 3 enclosing purlin 2 and middle part at fender post 1 top and being arranged on
Concrete support 8 on steel column 9 tiltedly throws support 7 composition with steel, and described concrete support 8 is the horizontal support structure being provided with bracket 6
Part, concrete support 8 is arranged on steel column 9 and one end is fixing with the waist rail 3 of fender post 1 is connected, its other end and opposite side waist
Beam 3 is fixing to be connected；Support 7 tiltedly thrown by described steel is the steel beam column of oblique pull, is connected to enclose the steel inside purlin 2 and tiltedly throws support 7, its one end with enclose
Connection fixed by the purlin 2 that encloses of fender pile 1, and the other end is fixing with the bracket 6 in Horizontal concrete support 8 to be connected；Described enclose purlin 2, waist rail 3
Support 7 and the fixing built-in fitting being connected of concrete support 8 is tiltedly thrown with steel with being equipped with on bracket 6；Described steel column 9 is arranged on coagulation
Soil supports the bracket 6 times of 8, bears concrete support 8 deadweight and steel is tiltedly thrown the steel column 9 of support 7 axle power and used steel structure column or steel
Pipe.
Refering to accompanying drawing 2～Fig. 3, this utility model is so construction: completes fender post 1, encloses purlin 2 and enclosing inside purlin 22
After burying the construction of built-in fitting 4 and steel column 9 underground, stay soil to put slope and be excavated to first and support the end, slope ratio for 1:1.5 ~ 1:2.0,
Casting concrete support 8 and bracket 6, and in bracket 6, bury built-in fitting 4 underground, at concrete support 8 end reserved steel bar, then
Fluting sets up steel and tiltedly throws support 7, soil excavation will be stayed complete, after pouring waist rail 3, pour concrete support 8 to waist rail 3 and push up reality,
Steel is tiltedly thrown the supporting of support 7 and is accelerated excavation of foundation pit speed, and foundation ditch top soil pressure is transferred to concrete support 8 He by tiltedly throwing support 7
Steel column 9, makes full use of the axial press capacity of concrete, and Appropriate application is as the steel column 9 of vertical applied force component simultaneously
Undertaking part soil pressure, shorten the whole construction period, reduce concrete amount, alleviate support system deadweight, bracing members is removed
After can recycle, save cost.
More than simply this utility model is further described, and is not used to limit this patent, all for this equivalence enforcement,
Within being intended to be limited solely by the right of this patent.
