Abstract
The invention discloses a long pile and short pile combined single-row pile and horizontal internal support pile supporting structure and a construction method thereof. The structure is characterized in that long piles and short piles are arranged in a staggering way at equal intervals in a single row of pile; the clear spacing between two adjacent piles is 200 to 400mm; two rows of concrete deep stirring piles are arranged behind a support pile to serve as a waterproof curtain; the layer number of internal supports is 1 to 3; the first layer of horizontal internal supports is generally arranged on the top of the support pile; the distance between the adjacent internal supports which are arranged up and down is 4 to 6m. When the supporting structure is designed, in all the rows of piles, parameters of the short piles are calculated to make sure that the requirements on the horizontal displacement, the bending capacity and the overturning resistance of the short piles are met and then parameters of the long piles are calculated to make sure that the requirement on the deep slide stability of the long piles is met. The construction method comprises the following main construction steps of constructing the long piles, constructing the short piles, constructing the concrete deep stirring pile curtain, hardening the ground before excavating a foundation pit, constructing a drainage facility, excavating the first layer of earth, constructing a pile top beam and the horizontal internal supports, excavating the second layer of earth, and performing the other steps until the earth is excavated to the bottom of the foundation pit.
Description
Technical field
The present invention relates to the Deep Foundation Pit Supporting Project technical field, specifically a kind of stake support supporting and protection structure and job practices thereof of single stake+horizontal inner support of length stake combination.
Background technology
In the Deep Thick Soft Ground Area Deep Thick Soft Ground zone of Wuhan Area particularly, in order to guarantee the Against Deep sliding of foundation ditch, monolithic stability, anti-protuberance is stablized requirements such as reaching overturning or slip resistance analysis, foundation pit supporting pile need to enter down the good ground that covers better performances through Deep Thick Soft Ground, the stake of soldier pile is long mainly to be determined by the buried depth that covers good ground under Soft Soil Layer, little with the cutting depth relation of foundation ditch self, in this case, when the excavation of foundation pit degree of depth is deepened, the general stake footpath that only needs to adjust soldier pile of design of its support, the layer t53fg number of the arrangement of reinforcement of pile body and additional horizontal inner support, the long variation of stake of soldier pile is little.The result caused thus is: for the foundation ditch of the middle deep about cutting depth 7 ~ 10m, its soldier pile length is more than 20m, even reach more than 30 meter, increased widely the cost of pattern foundation pit supporting structure, profligacy country and social resource, with the low-carbon environment-friendly theory of current whole society promotion, run in the opposite direction.
Summary of the invention
The present invention is directed to the long present situation that unanimously causes the social resources significant wastage of the long long and adjacent soldier pile stake of Deep Thick Soft Ground Area base pit engineering soldier pile stake, a kind of stake support supporting and protection structure and job practices thereof of single stake+horizontal inner support of length stake combination are provided, this foundation pit supporting construction and job practices thereof are applicable to any stratum, especially remarkable in the deep soft soil layer economic benefit.
The stake support supporting and protection structure of the single stake+horizontal inner support of a kind of length stake of the present invention combination, comprise: one is long and the other is short that interval is arranged for single stake, establish two draining earth deep-mixed piles after soldier pile and make water-stop curtain, be connected with the steel concrete waling on soldier pile, on the steel concrete waling, be connected with inner support.
Described single stake is single deposited reinforced concrete pile.
The cross sectional shape of described single deposited reinforced concrete pile is circular or square.
The stake footpath of described cement-soil mixing pile is 500mm, pile spacing 350mm, and row of piles is apart from 400mm.
The length stake equidistantly arranges, the clear spacing of adjacent two piles is 200 ~ 400mm, and the excessive effect of the barrier to weak soil of clear spacing reduces, and is unfavorable for anti-deep sliding stability requirement.
Described inner support is steel pipe support, shaped steel support or steel concrete support.
The number of plies of inner support depends on the excavation of foundation pit degree of depth, surrounding enviroment condition and sitework geological conditions etc., is generally 1 ~ 3 layer, and the 1st layer of horizontal inner support generally is located at the soldier pile top, and the spacing of neighbouring two-layer inner support is 4 ~ 6m.
The waling of described inner support is the steel concrete waling, and the waling of the 1st layer of horizontal inner support is steel concrete Guan Liang, and the waling of all the other each layer of horizontal inner supports is reinforced concrete waist rail.
When Foundation Pit Support Design is calculated, all campshed is first pressed stub calculating, guarantees that its horizontal movement, anti-bending bearing capacity, overturning or slip resistance analysis meet the demands; Then calculate by long stake, guarantee that its deep sliding stability meets the demands.
A kind of job practices of stake support supporting and protection structure of single stake+horizontal inner support of length stake combination, its step is as follows:
1. long pile driving construction: measure unwrapping wire, rig is in place, pore-forming, and clear hole, reinforcing cage system peace, conduit is installed, secondary pile hole cleaning, underwater concrete perfusion;
2. stub construction: measure unwrapping wire, rig is in place, pore-forming, and clear hole, reinforcing cage system peace, conduit is installed, secondary pile hole cleaning, underwater concrete perfusion;
3. cement-soil mixing pile curtain construction: deep mixer is located, and the preparation cement paste, stir sinking in advance, and whitewashing is stirred, promoted, and repeats stirring and sinks, and repeats to stir whitewashing and is promoted to aperture, shutdown, cleaning, displacement;
4. before excavation of foundation pit, to the ground in the 3～5m scope of top, slope, adopt the C20 plain concrete of thick 6～8cm to make cure process, in 1.0m left and right, top, distance slope, top, one slope catchwater is set;
5. the 1st layer of soil excavation is at the bottom of soldier pile stake apical cap beam;
6. Guan Liang construction;
7. the horizontal inner support construction of first floor;
8. descend one deck soil excavation;
If 9. the number of plies of horizontal inner support is more than 1 layer, successively by soil excavation at the bottom of the waist rail of each layer of horizontal inner support, each layer of horizontal inner support of constructing successively;
10. repeating step 8., by the pit earthwork stage excavation to foundation ditch bottom.
The stake support supporting and protection structure of the single stake+horizontal inner support of a kind of length stake of the present invention combination and job practices thereof adopt the stake support supporting and protection structure of the single stake+horizontal inner support of length stake combination, can save the consumption of the constructional materialss such as reinforcing bar, concrete, cement, duration can be saved again, thereby for the Construction Party reduces investment outlay, reduce the wasting of resources, reach the target of low-carbon environment-friendly, energy-saving and emission-reduction.
