Broken ground in the foundation ditch and reinforced, broken ground to reinforce to distinguish and adopt slip casting to reinforce. Broken ground in the foundation ditch and reinforced below for elevation at the bottom of the basement bottom plate 1 to 1.2 times of foundation ditch cutting depth of the degree of depth, broken ground and reinforce the width for 1.2-1.8m within the basement bottom plate edge.

Description

A kind of pattern foundation pit supporting structure ruggedized construction
Technical field
The utility model relates to pattern foundation pit supporting structure ruggedized construction, is applicable to the realm of building construction.
Background technology
Along with the development of urban construction; excavation of foundation pit has been tending towards large-scale and the large degree of depth; and be main mainly with Open Cut Method; work progress is along with extremely strong environmental effect; if do not carry out strict Deformation control to deep foundation pit construction; contiguous building can affect it and normally use because of moderate finite deformation, even accidents caused time serious, the economic loss caused and social influence are immeasurable.Therefore, Safety Construction of Deep Foundation Pit problem is the problem that engineers and technicians pay close attention to.
Utility model content
The utility model is to provide a kind of pattern foundation pit supporting structure ruggedized construction, solves the problem of foundation pit support construction safety.
For this reason, the utility model comprises capping beam, ground tackle, anchor pole, three axes agitating pile, shaped steel, stabilization zone of being broken ground, waist rail.
Foundation ditch capping beam adopts Two bors d's oeuveres channel-section steel, soldier pile adopts three axes agitating pile to insert shaped steel mode, three axes agitating pile stake footpath is 600 ~ 700mm, three axes agitating pile overlap joint 200mm, three axes agitating pile arranged outside water-stop curtain, the water-stop curtain degree of depth is 2.5 ~ 3 times of the excavation of foundation pit degree of depth, it is 14 ~ 20m that anchor pole inserts margin of foundation pit foundation soil length, anchor pole inclination angle is 20 ° ~ 25 °, anchor pole is full length fastening bonding, anchor pole tensioning lock definite value is 50kN, and first floor anchor pole is fixed on capping beam by ground tackle, and second layer anchor pole is fixed on waist rail by ground tackle.Broken ground in foundation ditch and reinforce, stabilization zone of being broken ground adopts grouting and reinforcing.Reinforcement depth of being broken ground in foundation ditch is below absolute altitude at the bottom of basement bottom board 1 to 1.2 times of excavation of foundation pit degree of depth, and reinforcing width of being broken ground is 1.2 ~ 1.8m within basement bottom board edge.
The utility model load is reliable, and stress performance is good, and degree of safety is high.
Accompanying drawing explanation
Fig. 1 is pattern foundation pit supporting structure ruggedized construction schematic diagram.
In each accompanying drawing: 1, capping beam, 2, ground tackle, 3, anchor pole, 4, three axes agitating pile, 5, shaped steel, 6, by stabilization zone of breaking ground, 7, waist rail.
Detailed description of the invention
Place complicated geology residing for certain Deep Foundation Pit, underground utilities complex distribution near foundation ditch.Near foundation ditch, 15 ~ 20m place also has building, and safety requirements is high.Foundation ditch shape very irregular, foundation ditch area is 7850m 2, excavation of foundation pit, the degree of depth is 5.35m.This place's groundwater table is higher, is distributed with the mud that thickness reaches 15m.
As shown in the figure, the present embodiment comprises capping beam, ground tackle, anchor pole, three axes agitating pile, shaped steel, stabilization zone of being broken ground, waist rail.Foundation ditch capping beam 1 adopts Two bors d's oeuveres channel-section steel, soldier pile adopts three axes agitating pile 4 to insert shaped steel 5 mode, three axes agitating pile 4 footpaths are 600 ~ 700mm, three axes agitating pile 4 overlaps 200mm, three axes agitating pile 4 arranged outside water-stop curtain 8, water-stop curtain 8 degree of depth is 2.5 ~ 3 times of the excavation of foundation pit degree of depth, it is 14 ~ 20m that anchor pole 3 inserts margin of foundation pit foundation soil length, anchor pole 3 inclination angle is 20 ° ~ 25 °, anchor pole 3 is full length fastening bonding, anchor pole 3 tensioning lock definite value is 50kN, first floor anchor pole 3 is fixed on capping beam 1 by ground tackle 2, second layer anchor pole 3 is fixed on waist rail 7 by ground tackle 2.Broken ground in foundation ditch and reinforce, stabilization zone 6 of being broken ground adopts grouting and reinforcing.Reinforcement depth of being broken ground in foundation ditch is below absolute altitude at the bottom of basement bottom board 1 to 1.2 times of excavation of foundation pit degree of depth, and reinforcing width of being broken ground is 1.2 ~ 1.8m within basement bottom board edge.
Be provided with monitoring point for displacement in foundation pit slope protection stake, carry out long term monitoring to excavation slope, arrange 26, monitoring point altogether, according to Surveillance data statistics, base pit stability is good, and accumulative displacement value is all within 16mm, and single shift value is within 2mm, and whole slope is stablized.
