Dissipate, it is to avoid deformation.
Further, the precast frame is square hollow steel pipe, and cross-sectional width is 5-10cm, after fixation and hollow
Steel duct carries out mortar and poured into so that individual layer reinforced mesh is more consolidated.
Application method of the present utility model is：After the construction of deep basal pit surrounding fender post is finished, excavation of foundation pit certain depth, in
Cast-in-situ bored pile pile body sets bushing type expansion bolt, using boom hoisting, and Heave Here is placed in lifting strenthening member, by steel
Muscle mesh sheet is even hung between pile body side wall and expansion bolt end, is then welded horizontal beading and expansion bolt end so that
Closely connected cast-in-situ bored pile and the vertical muscle of reinforced mesh is expressed on the outside of horizontal beading and reinforced mesh, to pouring into sand in precast frame
In individual layer reinforced mesh top layer gunite concrete after slurry, that is, spray anchor concrete layer so that face soil body side in foundation ditch and be wrapped in spray
Among the concrete penetrated, then by excavation of foundation pit to projected depth.
The beneficial effects of the utility model are compared with prior art：The utility model is mainly to traditional suspended net shotcrete foundation ditch
Enclosing Technique is improved, by setting bushing type expansion bolt in pile body, horizontal beading with expansion bolt spot welding firmly, can
Lean on, and extrude individual layer reinforced mesh, be allowed to fixed, prevent from coming off, lifting strenthening member can avoid lifting from deforming, and that sets up is prefabricated
Framework to consolidate indeformable, suspended net shotcrete building enclosure between formation stake in individual layer reinforced mesh top layer gunite concrete, protected
Leak does not occur, sand is gushed for card foundation pit side-wall, reaches the target for reducing foundation ditch risk, is soft especially for foundation pit side-wall inter-pile soil
The situation of weak soil layer, fixes reinforced mesh with the method that spot welding is combined using expansion type and then forms the higher reinforcing bar of intensity
Concrete structure, effectively reduces foundation pit enclosure structure deformation, reaches deep footing groove enclosing structure intensity height, the mesh of good integrity
's.Suspended net shotcrete technology is improved about than suspended net shotcrete techniques intensity between traditional stake between the stake of expansion type fixation reinforced mesh
30%, the repair rate after mesh sheet comes off reduces by 95%, and the duration shortens 30%, it is not necessary to which large-scale equipment is with installing equipment, construction
Technique is simple, and construction quality is guaranteed, and can more effectively ensure Extra-Deep Foundation Pit safety.The utility model mainly for
Foundation pit side-wall m esh-hanging sprayed concrete reinforced mesh fix loosely, a set of expansion type of the design that comes off fixed between the stake of reinforced mesh
Suspended net shotcrete building enclosure, the technology construction application scope is wide, work progress simple, short time limit, fixation, reliable, intensity
High, quality is easily guaranteed that.
