The utility model is achieved in that multiple tracks annular concrete support pit earthwork outward transport construction provided by the utility model
Structure, including concrete supporting construction and multiple tracks annular concrete supported beam 12 in the soil body are formed, concrete supporting construction has multiple edges
The stand column pile 11 of foundation depth Longitudinal extending, and multiple stand column pile 11 are arranged around the periphery of foundation ditch, multiple tracks annular concrete supported beam
12 along the longitudinally spaced arrangement of foundation depth so that foundation pit side-wall keeps uniform force.
It is corresponding in the range of ramp 16 in adjacent annular concrete supported beam 12, multiple post plates 13 are set, the two of post plate 13
End is connected on adjacent annular concrete supported beam 12, multiple 13 laterally adjacent arrangements of post plate, and forms enclosed construction, this knot
The interim soil-baffling structure system of one of barricade of post plate 13 is configured to, can stop that the earthwork is back to support beam 12 when ramp 16 backfills
The problem of lower section, the backfilling of earthwork amount avoided at ramp 16 is big, and construction repeats.
During practice of construction, including following construction procedure：
1), smooth location to first of concrete supported beam 12 bottom absolute altitude, and construct first of annular concrete supported beam 12 so that
First of annular concrete supported beam 12 is connected with multiple stand column pile 11, forms the annular of closing, can so cause foundation pit side-wall by
Power is uniform；The embedded bar 14 on the position at the soil outlet of ramp 16 of concrete supported beam 12 simultaneously；
2), the earthwork that foundation ditch first layer is dug out, outwards transported by the way of ramp 16, continue earth excavation to second
The bottom absolute altitude of concrete supported beam 12, the earthwork in the range of ramp 16 is all excavated, second annular concrete supported beam 12 of then constructing,
So that second annular concrete supported beam 12 is connected the annular for forming closing with multiple stand column pile 11；It is located in the second concrete supported beam 12
Embedded bar 14 on position at the soil outlet of ramp 16；
3), before in the range of by backfilling of earthwork to ramp 16, in first of annular concrete supported beam 12 and second annular
Post plate 13 is set between concrete supported beam 12, and post plate 13 passes through reinforcing bar 14 and first annular concrete supported beam 12 and second respectively
Annular concrete supported beam 12 connects, and so forms an overall structure of post plate 13, and this structure forms the interim of one barricade of post plate 13
Soil-baffling structure system, the earthwork during backfill of ramp 16 can be avoided to be back to the lower section of support beam 12；After post plate 13 is constructed, on slope
The earthwork is backfilled in the range of road 16, recovers slight slope road 16；
4), foundation ditch continue down the construction and excavation earthwork when, when using ramp 16 when, according to construction procedure 3) method behaviour
Make, post plate 13 is set between adjacent annular concrete supported beam 12.
5) in construction procedure 4) after, when need not construct ramp 16 when, will last one of concrete supported beam 12 with it is upper together with concrete
The construction of post plate 13 between support beam 12 is completed, and forms a complete overall structure of post plate 13, then using the relay of excavator 17
Soil and grab bucket 18 are unearthed.
Above-mentioned multiple tracks annular concrete support pit earthwork outward transport constructing structure, annular concrete supported beam 12 are located at the orientation of ramp 16
Position be embedded with reinforcing bar 14, post plate 13 is connected by reinforcing bar 14 with annular concrete supported beam 12, for the connection bone next constructed
Frame provides firm tie point.
Connecting framework is connected with annular concrete supported beam 12, connecting framework is vertically arranged, and post plate 13 is connected with connecting framework,
So, post plate 13 and annular concrete supported beam 12 can be caused closely to link together, it is overall to form a firm post plate 13
Structure.
In the present embodiment, connecting framework is connection channel-section steel 15, and it plays support and fixed effect to post plate 13 so that shape
Into the overall structure of post plate 13 have enough intensity, the pressure in 16 cubic metres of earth of ramp can be born.
In the present embodiment, the both ends of post plate 13 are connected with annular concrete supported beam 12 respectively, can so cause the He of post plate 13
Connect between concrete supporting construction and more consolidate, and interval, post plate 13 between the inner side at the middle part of post plate 13 and stand column pile 11 be present
Ramp is isolated for 16 cubic metres of earth with the underlying space of support beam 12, reduces construction workload.
Along foundation depth direction, mutually abutted between the end of adjacent post plate 13, and in the range of ramp 16, two rings
Multiple post plates 13 between shape concrete supported beam 12 form enclosed construction.So, the structure of post plate 13 of a sealing is formed, can be very
Good keeps apart the earthwork and the space of the lower section of support beam 12.
Along the depth direction of foundation ditch, last one of concrete supported beam 12 on together with the structure of post plate 13 between concrete supported beam 12 apply
After the completion of work, between adjacent post plate 13, ramp 16 is ladder-like arranged, and is so advantageous to the relay of excavator 17 and falls native and grab
Bucket 18 is unearthed, and completes last unearthed work.
In the present embodiment, multiple tracks annular concrete support pit earthwork outward transport constructing structure also includes excavator 17 and grab bucket
18, when need not construct ramp 16 when, ramp 16 is arranged into a ladder, excavator 17 is placed on the ladder at interval, each to dig
Toward adjacent ladder, soil, the last earthwork are caught pick machine 17 using grab bucket 18.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
