Abstract
The utility model discloses a dark excavation supporting's interior bearing structure waters district behind the structure post position, supports the concrete column pile cluster by supporting steel stand, reinforced concrete collar tie beam, cellar structure beam slab, the reinforced concrete contignation reinforcing body, basement beam slab department, sets up reinforced concrete collar tie beam and the reinforcing of reinforced concrete contignation in cellar structure floor elevation position and personally experiences sth. Part of the body and be under construction simultaneously and be connected with the support post with the cellar structure beam slab. Can strengthen excavation supporting overall stability greatly, improve the excavation supporting security, consequently the excavation supporting construction period shortens construction period for cellar structure construction stage promptly greatly. As permanent structure, having avoided demolition construction simultaneously, having avoided supporting and demolishd the wasting of resources that causes, reduced the construction process simultaneously, construction process is simple, and economic benefits is outstanding, is the dark excavation supporting's interior bearing structure of an ideal.
Description
Technical field
The present invention relates to the technical field of deep foundation pit support, the inner supporting structure shape of more particularly to a kind of deep foundation pit support
Formula.
Background technology
In recent years, develop along with expressway around city, land resource is day by day rare, development profit of the urban construction to the underground space
With more and more, pattern foundation pit supporting structure utilizes an indispensable part, support pattern to become more diverse as the underground space, supporting skill
Art also reaches its maturity.The continuous development utilized with skyscraper and the underground space, corresponding multi-storey basement, subterranean tunnel,
The supporting foundation such as ferrum, commercial street, makes engineering yet to be built usually adjacent to skyscraper or underground structure etc., as people's right-safeguarding is anticipated
The raising of knowledge often also causes the space that foundation pit supporting construction cannot temporarily beyond occupied ground red line so that foundation pit anchor, anchor
The use of the anchor system such as rope receives certain restriction, and inner supporting structure then avoid well support system to red line with
The impact occupied problem, reduce to external world of the outer underground space, using being also increasingly taken seriously.Traditional inner support is main
There are temporary steel support, temporary concrete to support and basement top-down method, and temporary steel support anti-bending strength and stability in the large
Poor, support stress is little often to cause support interval little, and steel usage amount is greatly, big to later stage earth excavation construction infection, construction
Period is installed with dismounting and to supporting protective measure to have high demands, and cost is high.Temporary concrete support can according to foundation ditch flat shape,
The layout pattern for building up relatively optimization is poured, and the rigidity for supporting is big, stability in the large is good, and stress is big, the advantages of easy construction, but its
For temporary project, as the basement structure construction stage need to carry out bracing demolition, Demolition Construction difficulty is big, long in time limit easily to week
Side impacts safely, and temporary concrete inner support can not be reused, and a large amount of building wastes is produced after dismounting and causes resource
It is a large amount of to waste.And though traditional basement top-down method need not additionally arrange support system, to basement structure and basic shape
Formula has particular/special requirement, needs a large amount of precast construction posts, and underground chamber base must use pile foundation, and is one pile for one column shape
Formula, structure node is complicated, complicated construction technique, and construction technical requirement is high, and existing needs to increase substantial amounts of pile foundation, earthwork work
Journey needs the high defect of the unfavorable factor construction period such as tunneling length, engineering cost, and to pattern foundation pit supporting structure construction many deficiencies are brought.
The content of the invention
The technical problem to be solved be to provide it is a kind of it is safe and reliable, convenient and swift, when effectively can save construction
Between and reduce construction cost, a kind of inner supporting structure of deep foundation pit support of environmental protection.
To achieve these goals, technology of the invention solves to put case is：A kind of inner supporting structure of deep foundation pit support by
Diaphram wall campshed, reinforced concrete circle beam, basement structure beam slab, reinforced concrete beam and plate reinforcement, supporting steel
Column, structural column reserve Hou Jiao areas, outdoor ground, support concrete column stake composition；Holding force is drilled into using mechanical stake machine
Lifting after layer supports steel column, carry out stand column pile base concrete pour be combined into steel column and stand column pile support is vertical to be carried
Component, a reinforced concrete circle beam, collar tie beam and underground are arranged in basement structure floor elevation location along building enclosure edge
Diaphragm wall campshed and basement structure beam slab are attached, and avoid basement structure post position and arrange reinforced concrete beam and plate
Reinforcement, reinforced concrete beam and plate reinforcement is attached with steel column is supported, reinforced concrete collar tie beam, basement structure
Beam slab, the reinforcing bar of reinforced concrete beam and plate reinforcement should simultaneously carry out colligation, and concrete is poured simultaneously, ground when pouring
The reserved Hou Jiao areas of lower room contignation and basement structure post binding site, make reinforced concrete collar tie beam, basement structure beam slab,
Reinforced concrete beam and plate reinforcement is poured jointly becomes a structure entirety and support post is connected to become one reliably
Inner supporting structure.
Described reinforced concrete inner support structure can need to arrange one or more layers according to the basement number of plies.
Described basement contignation treats that excavation of foundation pit is completed with the reserved Hou Jiao areas of basement structure post binding site, enters
Row basement structure post is poured simultaneously when constructing, alternative after basement structure post concrete strength reaches design requirement
Steel column is supported, and steel column will be supported to be removed.
Beneficial effects of the present invention：Using arrange reinforced concrete collar tie beam and reinforced concrete beam and plate reinforcement and
Basement structure beam slab and basement structure post junction arrange Hou Jiao areas, pour jointly with reference to basement structure beam slab and with
Support column effectively connection becomes a permanent structure, can greatly enhance pattern foundation pit supporting structure stability in the large, improves pattern foundation pit supporting structure safety
Property, therefore be the basement structure construction stage during foundation pit support construction greatly shortens construction period.Simultaneously as permanent knot
Structure, it is to avoid Demolition Construction, it is to avoid the wasting of resources that supporting removal is caused, while reduce working procedure, construction technology letter
Single, economic benefit is projected, and is a kind of inner supporting structure of preferable deep foundation pit support.
Description of the drawings
Utility model invention is further described with reference to the accompanying drawings and detailed description.
Accompanying drawing 1 is a kind of inner supporting structure floor map of deep foundation pit support.
Accompanying drawing 2 is a kind of inner supporting structure elevational schematic view of deep foundation pit support.
In figure：1st, diaphram wall campshed, 2, reinforced concrete circle beam, 3, basement structure beam slab, 4, armored concrete
