Set up bracing members at interval of certain distance in foundation ditch between cover plate, in the soil body in described hole, open up pre- grooving, described bracing members
It is arranged in described pre- grooving, described cover plate bottom is fixedly connected with prefabricated hook member, described prefabricated hook member is along described
The length direction arrangement of bracing members.
While using technique scheme, the utility model can also adopt or combination is using further below
Technical scheme：
The top of described foundation ditch sets up reinforced concrete support, and described reinforced concrete support is arranged on described pre- grooving
Interior, described cover plate is erected on described reinforced concrete support.
When reaching bracing members installation site, the bracing members in pre- grooving are lifted to by steel strand wires using hoisting equipment
Designed elevation, and installed.
Described prefabricated hook member includes reinforcing bar crotch, prefabricated steel and suspension hook, and described reinforcing bar crotch hangs and is welded on
In the cage bar of cover plate, described prefabricated steel is fixedly connected on reinforcing bar crotch lower end, and described suspension hook is fixedly connected on described pre-manufactured steel
On plate.
After the completion of prefabricated hook member welded and installed, using cover plate concrete, cover plate is poured.
The beneficial effects of the utility model are：Structure of the present utility model can be in the base pit engineering of cover and cut method construction
In, by the method for grooving embedded steel tube, carry out Horizontal steelwork bracing in any absolute altitude using prefabricated hook member and hoisting equipment
Lifting, system is reliable, simple operation, overcomes the bracing members lifting causing in cap excavation method foundation pit construction due to narrow space
Difficult.

Specific embodiment
Referring to the drawings.
Gai Shun of the present utility model digs the foundation pit structure of practice construction, including the soil body 1, structure base slab 6 and cover plate 4 in hole,
Described foundation ditch the week side of boss is provided with diaphram wall 3, at interval of a spacing in the foundation ditch between described structure base slab 6 and described cover plate 4
From setting up bracing members 5, open up pre- grooving 7 in the soil body 1 in described hole, described bracing members 5 are arranged in described pre- grooving 7, described
Cover plate 4 bottom is fixedly connected with prefabricated hook member 8, and prefabricated hook member 8 is by reinforcing bar crotch 14, prefabricated steel 15 and suspension hook 16
It is welded, reinforcing bar crotch 14 should be welded in cover plate cage bar 13.
Described prefabricated hook member 8 is along the length direction arrangement of described bracing members 5.
The top of described foundation ditch sets up reinforced concrete support 11, the structure of reinforced concrete support 11 and bracing members 5 phase
Same, it also is provided with the pre- grooving 7 supporting with reinforced concrete support 11 in the soil body 1 in hole, described reinforced concrete support 11 is arranged
In described pre- grooving 7, described cover plate 4 is erected on described reinforced concrete support 11.
Described prefabricated hook member 8 includes reinforcing bar crotch 14, prefabricated steel 15 and suspension hook 16, and described reinforcing bar crotch 14 hangs
And be welded in the cage bar 13 of cover plate 4, described prefabricated steel 15 is fixedly connected on reinforcing bar crotch 14 lower end, and described suspension hook 16 is fixing
It is connected in described prefabricated steel 15.After the completion of prefabricated hook member 6 welded and installed, using cover plate concrete 12, cover plate is carried out
Pour.
When foundation pit construction is carried out using cover and cut method, as shown in figure 1, carry out first levelling of the land, hole in external reinforcement and
Diaphram wall 3 is constructed, and starts grooving and pour first Guan Liang, support and cover plate 4 after diaphragm wall reaches design strength requirement,
Recover floor traffic 2, subsequently progressively excavate the soil body 1 in hole below 4 in cover plate and to each road bracing members absolute altitude and apply, excavation of foundation pit
Complete after-pouring bed course and structure base slab 6, finally carry out the construction of structure from bottom to top.
The installation of steel bracket as shown in Fig. 2 first according to bracing members design and installation position in the soil body 1 in hole in advance
Grooving 7, the bracing members 5 that need to set up at this are entirely within, and make prefabricated hook member 8 according to Fig. 5, and are welded and cover plate
4 bottoms corresponding position, carry out pouring of cover plate concrete 12, prefabricated suspension hook structure after the completion of prefabricated hook member 8 welded and installed
Part 8 and cover plate 4 should be adjusted according to bracing members deadweight, from suitable reinforcing bar label and plate size.
Pre- grooving 7 should be able to accommodate all bracing members 5 and prefabricated hook member 8 it is considered to first support of foundation ditch may be adopted
With concrete support, prefabricated hook member 8 can avoid concrete support arrangement.
As shown in figure 3, with the excavation of the soil body 1 in hole, when reaching first bracing members installation site, being set using elevator
Bracing members 5 in pre- grooving 7 are lifted to designed elevation by steel strand wires 10 by standby 9, and are installed.In the diagram, prefabricated suspension hook
Component 8 should be arranged symmetrically along bracing members 5 length direction to guarantee that during lifting, bracing members 5 keep balance.
