Description
Technical field
The present invention relates to foundation construction field of engineering technology, more specifically refer to a kind of foundation pit of network column supporting.
Background technique
The weak soil foundation pit of existing foundation construction, such as Collapsible Loess District weak soil, powder fine sand soil, miscellaneous fill, rubbish
The deep-foundation pit engineering of the engineering constructions such as rubbish soil field complex geologic conditions needs mostly since soil property is relatively soft to support base basis,
With the four sides soil nail wall on support base, progress is fully consolidated, and the design stability structure of foundation pit is difficult to ensure, foundation pit is caused to be easy
It collapses, construction is more troublesome.And existing foundation pit is fixed with Grouting Pipe consolidation and prestressed anchor mostly.Since Grouting Pipe does not have
There is guiding role, while the directionality of anchor pole is difficult to fix, is protected without the comprehensive support of grid posts, the consolidation of entire foundation pit
Stability is bad.Also, since Grouting Pipe does not have directionality, easily Grouting Pipe is caused to deform, anchor rod prestress direction changes, and makes
It is deviated at the prestressed anchor direction of foundation pit, foundation pit structure is stable and firm.
It is difficult to pore-forming in weak soil anchor bolt construction at present, the tensioning direction that not can guarantee prestressed anchor is stablized, Grouting Pipe
Directionality is poor, and the grid support capacity on support base is poor, and the surrounding of foundation pit is but reinforced without soil nail wall, and three is not effective
In conjunction with construction, whole foundation pit is difficult to ensure that foundation pit horizontal comparison and Vertical Settlement meet the requirements, it is difficult to bear soil pressure and hydraulic pressure
Power is pushed away effect, causes foundation pit is insecure to be easy to collapse, and causes house dangerous.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of foundation pits of network column supporting, using laterally fixed on support base
Xiang Guanwei Grouting Pipe locks prestressed anchor, while the waist rail of channel steel up and down of supporting network lattice column and channel steel waist rail welds, and is formed horizontal
It is fixed to vertical grid posts, while being arranged at intervals with soil nailing slip casting with Soil Nailing Wall alien invasion, structure is steady after foundation pit slip casting
It is fixed secured.
In order to solve the above technical problem, the present invention provides a kind of foundation pit of network column supporting, including it is foundation pit, anchor pole, fixed
To steel pipe and supporting network column；The bottom of the foundation pit is equipped with support base basis, fixed in the support base basis anchor pole,
Steel pipe and supporting network lattice column are oriented, the orientation steel pipe is slip casting shape steel tube, and slip casting locks the anchor pole, the protection support lattice
Column is located on the basis of the support base, is welded and fixed with channel steel waist rail, and be fixed on soil nail wall alien invasion, the supporting network lattice column
Interval is fixedly installed multiple soil nailings, and slip casting.
Further scheme is that the slip casting shape steel tube plays the angle of guiding and the control anchor pole.When slip casting shape steel tube
When slip casting, while playing the role of Grouting Pipe.
Further scheme is that the supporting network lattice column is the grid posts that iron staff is welded.Iron staff forms grid.
Further scheme, which is that the supporting network lattice column is connect with the channel steel waist rail, is welded into outer groove steel mesh lattice column, resists soil
Pressure and water pressure.
Further scheme is that the channel steel waist rail is divided into vertical channel steel support and lower vertical channel steel support, and uses mutually
The connection of anchor pole fixed block vertical welding.
Further scheme is that the support base basis hammers into soil solidifying by slip casting shape steel tube.Slip casting is by slip casting shape steel tube
Into, and carry out slip casting.
Further scheme is the 0.3-0.5m lower pad plank of the slip casting shape steel tube.It is easy for observing in this way, simultaneously
Play the role of rigid support, guarantees that the sinking Height Standard of foundation pit is no more than 0.3-0.5m.
Further scheme is that the anchor pole is prestressed anchor, is locked after grouting reinforcement tensioning with the channel steel waist rail.
Guarantee the stability of whole foundation pit.
Further scheme is, the slurries of the slip casting shape steel tube solidification mixed by cement, flyash, water and additive and
At.The solidification of injection slurry mixed proportion is strong.
Further scheme is that the anchor pole is HRB400 screw-thread steel.Bearing strength is big, resists soil pressure and hydraulic pressure.
Compared with the prior art, the invention has the advantages that: the foundation pit of inventive network column supporting is using horizontal on support base
It is Grouting Pipe to oriented tube, locks prestressed anchor, while the waist rail of channel steel up and down of supporting network lattice column and channel steel waist rail welds, shape
It is fixed at lateral and vertical grid posts, while being arranged at intervals with soil nailing slip casting with Soil Nailing Wall alien invasion, and oriented tube and pre-
Stress anchor pole orients slip casting, and soil nail wall is Ji Ba, and stable structure is secured after foundation pit slip casting, and resistant to pressure and soil pressure is strong, and foundation pit is stablized
Ground is secured.
