Abstract
Stop well construction between a kind of underground deep space of soft soil foundation, it is characterized in that, the structure is included by the 1.2m of stake footpath 0.5, the long single shaft or multiaxis cement mixing pile for exceeding parking well depth 1 10m of stake or the stake of SMW engineering methods enclose curtain as peripheral sealing, by the 1.5m of stake footpath 0.7, the long cast-in-situ bored pile or interlocking pile for exceeding parking well depth 8 30m of stake is used as exterior wall, segmentation formwork pours into a mould thick 0.3 0.8m armored concrete interior wall from the top down or from below to up, shaft bottom is reinforced concrete floor and plain concrete back cover layer, plane is square or rectangle well type structured, underlie the waterstop that is made up of 5 10m solid cements mixing piles or high-pressure rotary jet grouting pile in back cover layer.Compared with prior art, can be used in the city business district of China coast soft soil foundation, with shaft bottom soil layer not on gush, required construction site is small, and construction equipment is simple, and speed of application is fast, low engineering cost, the advantages of water-tight.
Description
Technical field
The present invention relates to the well construction that stopped between building field, more particularly to a kind of underground deep space of soft soil foundation.
Background technology
It is well known that city parking difficulty is a bottleneck of current city development, it is also an important project supported by commen people, especially
It is Deposits in Eastern Coastal China soft soil foundation city parking difficulty it is even more serious, its reason be reform and opening-up in one's early years build cell by
In not planning long-range parking, basement or only one layer basement parking are not provided with substantially, nowadays, even if night roadside is all fully parked with
Private car, can not still meet growing private car parking and require.
The content of the invention
Stop well construction between a kind of underground deep space of soft soil foundation of present invention offer, can be in China coast soft soil foundation
City business district is used, small with required construction site, shaft bottom soil layer not on gush, construction equipment is simple, and speed of application is fast, engineering
Cost is low, the advantages of water-tight.
Stop well construction between a kind of underground deep space of soft soil foundation of the present invention, it is characterised in that the structure include by
Stake footpath 0.5-1.2m, the long single shaft or multiaxis cement mixing pile for exceeding parking well depth 1-10m of stake or the stake of SMW engineering methods are as periphery
Sealing encloses curtain, by stake footpath 0.7-1.5m, the long cast-in-situ bored pile or interlocking pile for exceeding parking well depth 8-30m of stake as exterior wall,
Segmentation formwork pours into a mould thickness 0.3-0.8m armored concrete interior wall from the top down or from below to up, and shaft bottom is reinforced concrete floor
And plain concrete back cover layer, plane be it is square or rectangle well type structured, back cover layer underlie have 5-10m solid cements mixing pile or
The waterstop of high-pressure rotary jet grouting pile composition.
The present invention compared with prior art, can be used in the city business district of China coast soft soil foundation, with shaft bottom soil
Layer not on gush, required construction site is small, and construction equipment is simple, and speed of application is fast, low engineering cost, the advantages of water-tight.
Brief description of the drawings
Fig. 1 is diagrammatic cross-section of the embodiment of the present invention.
Drawing explanation：1 miscellaneous fill, 2 soil cement water-stop curtains, the borehole wall in 3,4 wellholes, the outer borehole wall of 5 cast-in-situ bored piles, 6 become silted up
Mud layer, 7 argillic horizons, 8 gravel layers, 9 soil cement waterstops, 10 concrete sealing bottoms layer, 11 reinforced concrete floors.
Embodiment
According to Fig. 1, the embodiment construction procedure for the well construction that stopped between a kind of underground deep space of soft soil foundation is as follows：
1. at the construction field (site), cast-in-situ bored pile (5) of the construction diameter 1m length from ground to gravel layer (8).
2. in wellhole (4) bottom argillic horizon (7), with the thick soil cement waterstops (9) of churning ram machine construction 8m, filled in drilling
Note on the outside of stake (5), with the native water-stop curtain (2) of mixing pile machine construction 1.2m solid cements.
3. water filling digs a well the interior soil body to shaft bottom absolute altitude, then tremie concrete back cover layer (10).
4. after concrete sealing bottom layer (10) intensity reaches, drawn water in pit shaft (4), making reinforcing bar by existing construction technology mixes
Solidifying soil bottom plate (11).
5. it is segmented formwork from bottom to top by current art and pours 0.6m thickness armored concrete Inner walls (3), that is, completes a kind of soft
The construction of parking well construction between the underground deep space of soil base.
Claims (1)
1. stop well construction between a kind of underground deep space of soft soil foundation, it is characterised in that the structure is included by stake footpath 0.5-
1.2m, the long single shaft or multiaxis cement mixing pile for exceeding parking well depth 1-10m of stake or the stake of SMW engineering methods are enclosed as peripheral sealing
Curtain, by stake footpath 0.7-1.5m, the long cast-in-situ bored pile or interlocking pile for exceeding parking well depth 8-30m of stake as exterior wall, on to
Lower or segmentation formwork cast thickness 0.3-0.8m from below to up armored concrete interior wall, shaft bottom is that reinforced concrete floor and element are mixed
Solidifying grave bottom, plane is square or rectangle well type structured, and underliing in back cover layer has 5-10m solid cements mixing pile or high pressure rotation
Spray the waterstop of stake composition.
