Abstract
The utility model discloses a kind of double sheet-pile wall revetment structure suitable for deep soft soil foundation,Mainly by preceding,Heel row sheet pile wall,And before connection,The top cast-in-place concrete cushion cap composition of heel row sheet pile wall,Before wherein,Heel row sheet pile wall can be by campshed,Prefabricated sheet pile or ground-connecting-wall are formed,Before,The soil body carries out basement process by rotary churning pile etc. between heel row sheet pile wall,Form the silo structure of one and half gravity type,The utility model not only avoid the earth excavation in narrow zone,Adapt to the Deep Thick Soft Ground geological conditions of features as poor geologic condition,The soil pressure of the high backfill in sheet pile rear can be carried,Meet the requirement of resistance to overturning,And structural reliability is high,It is good to control revetment horizontal displacement effect,Have a extensive future,It is particularly suitable for use on deep soft soil foundation,The forward position depth of water is deeper,Build narrow space,The regions such as surrounding enviroment complexity.
Description
Technical field
It the utility model is related to the revetment in water conservancy, marine traffic engineering, and in particular to a kind of double sheet-pile wall revetment structure, can
It is adapted to deep soft soil foundation.
Background technology
The important component that revetment connects as land and water, the extensive use in water conservancy, marine traffic engineering, recently as sea
The development in continuous city and coastal city, increasing requirement of engineering in city river and the newly-built revetment of city coastal region,
Newly-built revetment is frequently subjected to the forward position depth of water, geological conditions, builds the limitation such as place, surrounding enviroment in city.Deep Thick Soft Ground at present
Revetment structural shape on base often uses pile foundation reinforced concrete buttress type structure or the pull-type sheet-pile structure of anchor, and is close to sea or river course
Newly-built revetment, then need newly-built cofferdam to form dry work according to pile foundation reinforced concrete buttress type structure, applied so as to greatly increase
Work difficulty and construction investment, the pull-type sheet-pile structure of anchor can then be limited by construction place can not arrange anchor structure.
Utility model content
In order to solve the above-mentioned technical problem, the utility model proposes a kind of double sheet pile wall suitable for deep soft soil foundation
Revetment structure, solve the problems, such as deep soft soil foundation constructional difficulties.
Technical solution adopted in the utility model is as follows：
A kind of double sheet-pile wall revetment structure suitable for deep soft soil foundation, by forward and backward row's sheet pile wall, and connection institute
The cast-in-place concrete cushion cap composition on forward and backward row's sheet pile wall top is stated, wherein forward and backward row's sheet pile wall is by campshed, prefabricated board
Stake or ground-connecting-wall are formed, and soil stabilization body is provided between forward and backward row's sheet pile wall, so form the silo of one and half gravity type
Structure.
It is preferred that the soil stabilization body is by carrying out churning pile foundation to the soil body between forward and backward row's sheet pile wall
Processing is formed.
It is preferred that it is provided with back fill course above the cast-in-place concrete cushion cap.
Beneficial effect：The utility model not only avoid the earth excavation in narrow zone, adapt to the depth of features as poor geologic condition
Thick Soft Clay condition, the soil pressure at forward and backward row's sheet pile wall rear can be carried, meet the requirement of resistance to overturning, and structure
Reliability is high, good to control revetment horizontal displacement effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1 front-seat sheet pile wall, 2 heel row sheet pile walls, 3 cast-in-place concrete cushion caps, 4 back fill courses, 5 soil stabilizations
Body, 6 design mud upper threads.
Embodiment
As shown in figure 1, a kind of double sheet-pile wall revetment structure suitable for deep soft soil foundation, by forward and backward row's sheet pile wall
1st, 2, and the forward and backward row's sheet pile wall 1 of connection, the cast-in-place concrete cushion cap 3 on 2 tops form, the cast-in-place concrete cushion cap 3 is set up
In on forward and backward row's sheet pile wall 1,2, the cast-in-place connection of node, wherein forward and backward row's sheet pile wall 1,2 by campshed, prefabricated sheet pile or
Ground-connecting-wall is formed, and forward and backward row's sheet pile wall 1,2 is two rows, and soil stabilization body 5, such shape are provided between forward and backward row's sheet pile wall 1,2
Into the silo structure of one and half gravity type；The soil stabilization body 5 is by being carried out to the soil body between forward and backward row's sheet pile wall 1,2
Rotary churning pile basement process is formed, and certainly also other methods that can reach this effect, is not repeated herein.The cast-in-place concrete is held
The top of platform 3 is provided with back fill course 4.The forward position of front-seat sheet pile wall 1 is design mud upper thread 6.The utility model is suitable for deep soft
Soil base.
A kind of construction process of double sheet-pile wall revetment structure suitable for deep soft soil foundation is as follows：
1st, structure monolithic stability, intensity etc. are carried out according to the current specifications of revetment structure to calculate, determines that the insertion of sheet pile is deep
Degree, basement process scope etc..
2nd, the calculating of pile foundation intensity is carried out according to the current specifications of sheet-pile structure, determines that front and rear row pile-type, stake footpath, top are held
Platform thickness etc..
3rd, construction revetment bottom sheet-pile structure.
4th, rotary churning pile basement process between sheet pile before and after constructing.
5th, the construction cast-in-place suspended deck structure in revetment top.
6th, construction cast-in-place cushion cap top back fill course.
Claims (3)
- A kind of 1. double sheet-pile wall revetment structure suitable for deep soft soil foundation, it is characterised in that：By forward and backward row's sheet pile wall, And the cast-in-place concrete cushion cap composition on connection forward and backward row's sheet pile wall top, wherein forward and backward row's sheet pile wall is by row Stake, prefabricated sheet pile or ground-connecting-wall are formed, and soil stabilization body is provided between forward and backward row's sheet pile wall, so form one and half weights The silo structure of power formula.
