Description
Technical field
The invention belongs to construction engineering technical fields, and in particular to base pit engineering, more particularly to it is a kind of to be suitable for excavation face
The construction method of the larger deep foundation pit supporting structure of product.
Background technology
During urban development, soil more becomes deficient, effectively can constantly be reduced using land resource, but urban human
Mouth is but constantly expanding, and various engineerings are in underground and the opposite development trend in two kinds of space, engineering also in construction like a raging fire
Design, which directly results in foundation pit area, becomes increasing, and foundation depth is also constantly being deepened, and Construction of Deep Excavation Engineering undoubtedly becomes
The antecedent basis of all kinds of engineering constructions can not all despise in safety, quality, in terms of the duration.
In current Construction of Deep Excavation Engineering, have more universal to pattern foundation pit supporting structure is following two：
1. fender post adds reinforced concrete inner support
Concrete inner support pours and curing time is long, and the time that building enclosure is in unsupported exposed state is long, in weak soil
Big to passive area land movement, the supporting removal time is long, causes the foundation phase construction period long, and remove when due to dust, make an uproar
Sound generation effect on environment is big, and secondly a large amount of reinforced concrete inner supports increase construction costs；
2. fender post adds steel pipe to support
Steel pipe is higher to construction process requirement to supportting, node and support construction such as deal with improperly or Construction Support not in time, it is inaccurate
Really, unstability can be caused；For the foundation pit that area is larger, centre will add a large amount of lattice columns, to construction process requirement and high,
Very big inconvenience is brought to site operation simultaneously, total lever factor is influenced big.
Invention content
The present invention is in view of the above-mentioned problems, provide a kind of construction party suitable for the larger deep foundation pit supporting structure of excavation area
Method.
The purpose of the present invention can be realized by following technical proposals：A kind of deep basal pit larger suitable for excavation area
The construction method of supporting construction, includes the following steps：
（1）According to excavation of foundation pit sideline, constructs in foundation pit surrounding and enclosed by what water-stop curtain and several first cast-in-situ bored piles were constituted
Protection structure, the top construction Guan Liang of the first cast-in-situ bored pile are stirred in Foundation Pit bottom surrounding along building enclosure edge setting soil cement
A sub-merged pier is mixed to be reinforced to the foundation pit side soil body of building enclosure, several second cast-in-situ bored piles of construction and several the in foundation pit
Three cast-in-situ bored piles, several second cast-in-situ bored piles surround outer ring, and several third cast-in-situ bored piles surround inner ring；
（2）Using the soil body in central island-type in proportion slope excavation pit, make periphery soil excavation to default first of waist rail
Position and construct first of waist rail, so that central island soil excavation is enclosed to the substrate elevation location of third cast-in-situ bored pile fulcrum
First cast-in-situ bored pile of protection structure between third cast-in-situ bored pile fulcrum reserve the first back-pressure soil body, excavation pit center
First raft foundation in domain cubic metre of earth and central area of constructing；
（3）First of curved steel support is installed between first of waist rail and third cast-in-situ bored pile fulcrum, excavates first of oblique steel branch
The first lower back-pressure soil body of support makes the periphery soil excavation of the first back-pressure soil body to the position of default second waist rail and construction the
Two waist rails make central island soil excavation to the substrate elevation location of the second cast-in-situ bored pile fulcrum, the first of building enclosure bore
Hole pouring pile is to the second back-pressure soil body is reserved between the second cast-in-situ bored pile fulcrum, construct the second cast-in-situ bored pile fulcrum and third
The second raft foundation between cast-in-situ bored pile fulcrum；
（4）Second curved steel support is installed between second waist rail and the second cast-in-situ bored pile fulcrum, excavates the oblique steel branch of second
The second lower back-pressure soil body of support pours second curved steel support fulcrum to the third raft foundation at raft foundation edge, constructs the
The first load transfering strip between three raft foundations and the first cast-in-situ bored pile of building enclosure；
（5）Second curved steel support is removed, construction second curved steel support removes the first underground agent structure of rear region, backfill
The soil body between first underground agent structure and the first cast-in-situ bored pile of building enclosure agent structure and goes along with sb. to guard him knot under construction ground
The second load transfering strip between first cast-in-situ bored pile of structure；
（6）First of curved steel support is removed, first of curved steel support of constructing removes the second underground agent structure of rear region, backfill
The soil body between second underground agent structure and the first cast-in-situ bored pile of building enclosure.
Further, the step（1）In, the second cast-in-situ bored pile gives second oblique steel pipe support, third drill-pouring
Stake provides end reaction to first of oblique steel pipe support, the second cast-in-situ bored pile and third cast-in-situ bored pile with building enclosure together
Construction is completed, and the control of the absolute altitude of the second cast-in-situ bored pile and third cast-in-situ bored pile is in excavation of foundation pit face.
Further, the step（3）In, one end of first of oblique steel pipe support is supported on first of waist rail, and first
The other end of the oblique steel pipe support in road is supported on the first raft foundation；The step（4）In, one end of the oblique steel pipe support of second
It is supported on second waist rail, the other end of the oblique steel pipe support of second is supported on the second raft foundation；Wherein, first tiltedly
Steel pipe support and first of oblique steel pipe support are arranged in blossom type.
Further, the step（4）In, it is oblique to second after the concrete of the first load transfering strip of construction reaches intensity
Steel pipe support support replacement.
Further, the step（5）In, after the concrete of the second load transfering strip of construction reaches intensity, tiltedly to first
Steel pipe support support replacement.
Compared with prior art, the present invention efficiently uses construction structure underground structure raft foundation as inner support branch
Point, stage form back-pressure using the reserved soil body not excavated and ensure that foundation pit is stablized, the advantage is that：
1. cost-effectiveness：The armored concrete or steel pipe mentioned in inner supporting structure are gone along with sb. to guard him because substantially reducing similar background technology
Equal materials, cost are greatly reduced；
2. duration benefit：Either reinforced concrete inner support or steel pipe in the foundation pit supporting construction construction stage and tear support open
It is overall to occupy duration shortening except stage work amount is reduced；
3. environmental benefit：Without dust, noise pollution.
