Abstract
The utility model relates to architecture Foundation Pit Engineering technical field, especially a kind of deep basal pit steel suspension device.It includes stull, and is respectively arranged in the movable end and fixed end at stull both ends；The stull is multi-section structure, and flange surface connection is fastened by bolts between section and section；The outer end of the movable end is flexibly connected by connector with gad block；The outer end of the fixed end is fixed with oblique angle.Compared with existing many method for supporting, it has a characteristic that more intuitive to foundation pit walls application prestressing force, the supporting effect played is more preferable first is that having jack on its steel support structure；Second is that its south and north flanks in foundation pit uses different single dual-grippers, the supporting for different parts, specific aim is stronger.
Description
Technical field
The utility model relates to architecture Foundation Pit Engineering technical field, especially a kind of deep basal pit steel suspension device.
Background technique
City construction engineering makes full use of the underground space at present, a large amount of deep basal pit occurs.Changsha rail traffic 5
The foundation pit that there is south-north direction in the construction site line Hua Yazhan and depth is about 17.5~20.3m, and have by foundation pit and its by north orientation south
The increasingly closer viaduct pier of distance.The supporting of this kind of large deep foundation pit has campshed supporting, cement retaining wall, steel sheet pile, soil
The support patterns such as wall are followed closely, undesirable to the consolidation effect of soft soil, especially this kind of support action of silty clay, silt is non-
It is often limited.
Utility model content
The purpose of this utility model is to provide a kind of deep basal pit steel suspension devices.
The purpose of this utility model is achieved through the following channels: a kind of deep basal pit steel suspension device, it includes stull,
And it is respectively arranged in the movable end and fixed end at stull both ends；
The stull is multi-section structure, and flange surface connection is fastened by bolts between section and section；
The outer end of the movable end is flexibly connected by connector with gad block；
The outer end of the fixed end is fixed with oblique angle.
The connector and gad block are inserted in corresponding position equipped with what is mutually agreed with respectively as a further optimization of the solution,
Head and jack.
A kind of deep basal pit steel suspension device of the utility model, compared with existing many method for supporting, it has following special
Point: first is that having jack on its steel support structure, more intuitive to foundation pit walls application prestressing force, the supporting effect played is more
It is good；Second is that its south and north flanks in foundation pit uses different single dual-grippers, the supporting for different parts, specific aim is stronger.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the side view floor map of the utility model foundation pit；
Fig. 3 is the utility model fixed end overlooking structure diagram；
Fig. 4 is the utility model using state structure diagram.
Specific embodiment
As Figure 1-Figure 4, a kind of deep basal pit steel suspension device of the utility model, it includes stull 3, and is installed respectively
Movable end 17 and fixed end 15 in 3 both ends of stull；
The stull 3 is multi-section structure, is connected between section and section by 11 clamp flange disk 16 of bolt；
The outer end of the movable end 17 is flexibly connected by connector 1 with gad block 8；The connector 1 and gad block 8
The plug 18 and jack 4 mutually agreed with is equipped in corresponding position respectively.
The outer end of the fixed end 15 is fixed with oblique angle 10.
In use, first support two expansion bolts 12 of bracket 5 are consolidated when earth excavation is to first of bracing members absolute altitude
It is scheduled on diaphram wall 9, then welds together with the steel plate 13 on diaphram wall 9.6 lower part support of steel purlin is in bracket
On 5, top is using turnbuckle 7 together with enclosed structure drawknot.Steel purlin 6 is all connected and fixed using welding spreading
In 9 two sides of diaphram wall.Then bracing members are assembled, selection is carried out according to excavation of foundation pit width dimensions and bracing members length and is matched
It saves, is flange surface 14 between the tube coupling of stull 3, connected with flange bolt 11, be assembled into the single molding stull 3 for being entirely capable of lifting
Afterwards, once earth excavation is good, first the fixing end of single bracing members is sling, the oblique angle 10 in 15 disk of fixed end is gently placed
In the steel purlin 6 of side, then the connector 1 in the disk of movable end 17 is placed in the steel purlin 6 of the other side, is passed through
Jack 2 is placed in the centre of movable end 17 disk and steel purlin 6, applies top power to steel purlin 6 and stull 3, makes both ends
It combines closely with earth-retaining part contact position, after steel purlin 6 and building enclosure close contact, gad block 8 is then passed through into jack 4
With on connector 1 plug 18 mutually it is chimeric after stopper, finally lay down the pressure of jack 2 and dismantle.Foundation pit from overpass away from
Closer south, using double bracing members.When earth excavation second supports absolute altitude, the installation side of first of bracing members is repeated
Method.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art, can be without creative labor in the technical scope disclosed by the utility model
The dynamic change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection model of the utility model
Enclosing be determined by the scope of protection defined in the claims.
