Description
Technical field
The present invention relates to the inner supporting structure construction method of construction engineering technical field, more particularly to pattern foundation pit supporting structure, it is adaptable to underground
The structure time stage of building need to retain the situation of foundation ditch support system.
Background technology
In the development process of urban underground space, groups of building and infrastructure are more and more intensive so that underground engineering construction space
Reduce, construction environment is complicated；On the other hand, develop with the exploitation of the underground space towards direction that is extensive, complicating, ground
The excavation of foundation pit area and depth of lower engineering are increasing, the flexibility of underground structure arrangement and building requirements more and more higher.On ground
In lower engineering, due to the limitation of construction space, building requirements and site condition, for horizontal stroke of the control building enclosure under Water And Earth Pressures
To deformation, using needing to retain foundation ditch support system during the agent structure for building the close building enclosure of construction along the practice time, make
It continues stress, the just dismountable support until structure completes that lateral Water And Earth Pressures can be born.But in underground main structure construction
In often encounter agent structure and inner support collide resistance the problem of.Agent structure normal construction should be ensured, interior branch is ensured again
Safe and reliable support body system is the problem constructed.
The content of the invention
The invention reside in provide it is a kind of can meet effective support of foundation ditch, can guarantee that again underground structure smoothly return build and improve structure
Globality, and reduce cost, shorten the concrete inner support end of duration and use the construction method of shaped steel tectonic system, with full
The construction of the higher super large area deep foundation pit engineering of sufficient environmental requirement needs.
The object of the present invention is achieved like this：A kind of concrete inner support end uses the construction method of shaped steel tectonic system, should
Shaped steel tectonic system includes enclosure wall, encloses purlin, shaped steel, structural wall, horizontal support, seal plate band, and the purlin that encloses is fixed on institute
State on enclosure wall, horizontally disposed shaped steel is arranged on the enclosing between purlin and horizontal support of enclosure wall side, structural wall be located at enclosure wall with
Between horizontal support, the vertical reinforcement in structural wall is passed through from bottom to top from shaped steel both sides, and seal plate band is coated on shaped steel side,
Seal plate band at least surround shaped steel one week, and the seal plate band is located in the structural wall, and shaped steel two ends are fixed with shrouding, shrouding
It is respectively placed in and encloses in purlin and horizontal support, shrouding is provided with reinforcement.
It is preferred that a kind of concrete inner support end use shaped steel tectonic system construction method, it is characterised in that concrete construction method
It is as follows：Construct first enclosure wall, the excavation pit after its intensity reaches design requirement；Second step, treats in foundation ditch the soil body to level
More than supported design absolute altitude pre-buried shaped steel, assembling reinforcement concrete horizontal support and enclosed the reinforcing bar in purlin, then install horizontal support
And enclose the template of purlin, and pour into a mould concrete, construction shaped steel, horizontal support and enclose purlin；The support system for treating to be formed in second step
Concrete strength reaches progress subsoil body excavation after design requirement；Returned after 4th step, the solidifying earth foundation bottom plate of construction and build underground main body
Structure, constructing structure post, wall, beam, plate, when the structural wall close to foundation ditch side is constructed to horizontal support, incite somebody to action vertical from bottom to top
Reinforcing bar is passed through from the bottom to top from shaped steel both sides, integrated cast structure wall after supporting module, and structural wall coats the partial-length of shaped steel；5th
Step, returns and builds underground agent structure, to agent structure horizontal force System forming can braced cuts wall it is met deformation requirements when,
The part shaped steel stretched out on the inside of structural wall is cut off, whole road reinforced concrete support is removed.
The present invention a kind of concrete inner support end using shaped steel tectonic system construction method possess rational power transmission mechanism, can
Construction quality, easily construction process and the good economic benefit leaned on, not only ensure that excavation of foundation pit stage horizontal struts system reaches
To force request, resist building enclosure and occur transversely deforming, also speeded up construction speed, and reduce cost, improve construction
Quality.

Embodiment
The implementation of the present invention is described in detail below with reference to accompanying drawing.
A kind of concrete inner support end use shaped steel tectonic system construction method, the shaped steel tectonic system include enclosure wall 1,
Purlin 2, shaped steel 7, structural wall 5, horizontal support 9, seal plate band 6 are enclosed, purlin 2 is enclosed and is fixed on the enclosure wall 1, level
The shaped steel 7 of arrangement is enclosed between purlin 2 and horizontal support 9 installed in the side of enclosure wall 1, and structural wall 5 is located at enclosure wall 1 and level
Between support 9, the vertical reinforcement 8 in structural wall 5 is passed through from bottom to top from the both sides of shaped steel 7, and seal plate band 6 is coated on shaped steel
7 sides, seal plate band 6 at least surround shaped steel 7 one weeks, and seal plate band 6 is located in structural wall 5, and the two ends of shaped steel 7 are fixed with
Shrouding 4, shrouding 4, which is respectively placed in, to be enclosed in purlin 2 and horizontal support 9, and shrouding 4 is provided with reinforcement 3.
A kind of concrete inner support end uses the construction method of shaped steel tectonic system, and concrete construction method is as follows：
The first step, construct enclosure wall 1, the excavation pit after its intensity reaches design requirement；
Second step, is treated in foundation ditch more than the soil body to the designed elevation of horizontal support 9, pre-buried shaped steel 7, assembling reinforcement concrete horizontal
Support 9 and reinforcing bar in purlin 2 is enclosed, then install horizontal support 9 and enclose the template of purlin 2 and pour into a mould concrete, construction shaped steel 7,
Horizontal support 9 and enclose purlin 2；
3rd step, after the concrete strength of the support system formed in step 2 reaches design requirement, carries out lower floor's soil excavation；
Returned after 4th step, construction concrete foundation base plate and build underground agent structure, from bottom to top constructing structure post, wall, beam, plate,
When structural wall 5 close to foundation ditch side is constructed to horizontal support, vertical reinforcement 8 is passed through from the bottom to top from the both sides of shaped steel 7, installed
Integrated cast structure wall 5 after template, structural wall 5 coats the partial-length of shaped steel 7；
5th step, return build underground agent structure, to agent structure horizontal force System forming, can braced cuts wall 1, make it
When meeting deformation requirements, the part shaped steel 7 that the inner side of excision structural wall 5 is stretched out removes whole road reinforced concrete support.
