Description
Technical field
This utility model is related to diaphragm wall and excavates field, and more particularly to a kind of diaphram wall is fragile except pile crown.
Background technology
Diaphram wall excavation technology originates from Europe.It is to use mud and underwater pouring according to well-digging and oil drilling
The method of concrete and grow up, nineteen fifty in Milan, ITA initially with slurry coat method construction of diaphragm wall,
50 ~ sixties of 20th century, the technology was promoted in western developed country and the former Soviet Union, becomes underground engineering and deep foundation is applied
Effective technology in work.
Diaphram wall is that foundation engineering adopts a kind of trench machine on the ground, along the periphery axle of deep excavation project
Line, under the conditions of mud off, excavates out a long and narrow deep trouth, after clear groove, steel reinforcement cage is hung in groove, then use tremie method
Underwater concreting with tremie method builds up a unit groove section, so carries out paragraph by paragraph, builds up continuous reinforced concrete wall together in underground
Wall, as intercepting water, antiseepage, load-bearing, water-retaining structure.Basement, market place builet below the ground suitable for construction of buildings, parking lot, underground
Oil depot, retaining wall, the deep foundation of skyscraper, reverse construction building enclosure, the deep pond of industrial building, hole, vertical shaft etc..
In diaphram wall casting process, due in process of vibrating with inside concrete bubble or hole rising
It is laitance to stake top part, stake top certain limit, or mud during underwater concrete pouring, mortar mix, in order to ensure stake
The empty stake on top need to be cut by body concrete strength.
Only need to reach using the vertical pile body direction drilling of air drill, drilling depth during broken pile head at stake top setting
The 1/5 of stake footpath, then will separate in contract son insertion drilling, and be tapped using external force, until drill hole pile crown and stake
Body face produces separation, and then recurrence hangs out top pile crown.
Because which is more tight with internal bar connecting after concrete coagulation, is broken and separated more from reinforcing bar
Arduously, so needing to design a kind of diaphram wall fragile except pile crown.
Utility model content
The purpose of this utility model is that a kind of diaphram wall of offer is fragile except pile crown, and it has the spy for being easy to abolish
Point.
Above-mentioned purpose of the present utility model technical scheme is that:A kind of diaphram wall is fragile to be removed
Some sections of reinforcing bars of benchmark above ground level, the plastic tube being sheathed on some sections of reinforcing bars, for sealing in pile crown, including diaphragm wall
The sealing member in gap between plastic tube upper end open and plastic tube lower end and reinforcing bar, the reinforcing bar, plastic tube and sealing member
Poured in concrete together.
By adopting above-mentioned technical proposal, first plastic tube is arranged on reinforcing bar is above the ground level the lengths of rebar of the part of benchmark,
Then the opening of plastic tube upper end and lower end and the clearance seal of reinforcing bar, after such casting concrete, are mixed using sealing member
Solidifying soil is detached with reinforcing bar, there is no bonding relation between the two.When abolishing pile crown, staff only needs to abolish concrete
The bonding relation of itself, and without the need for viscous as what is will destroyed between concrete itself and concrete and rebar in prior art simultaneously
Relation is connect, compared to existing technology, the pile crown of the diaphram wall of the design is easy to be abolished.
This utility model is further arranged to:Diaphragm wall is above the ground level in the part of benchmark and is arranged at intervals with demarcation strip, institute
State in demarcation strip concreting.
By adopting above-mentioned technical proposal, if the concrete on pile crown can be divided into stem portion by demarcation strip, compare original
Integral structure, with demarcation strip segmentation after pile crown caking property reduce, it is easy to abolished.
This utility model is further arranged to:The sealing member includes covering the door held on the plastic tube and is sheathed on
Reinforcing bar and it is close to the rubber ring of plastic tube lower end.
Sealed by adopting above-mentioned technical proposal, door and rubber ring, for preventing concrete from touching reinforcing bar.
Rubber ring is elastomer, and which can preferably fill gap, so the sealing of rubber ring is preferable.Rubber ring is because have one simultaneously
Fixed elastic deformability, the requirement to quality of fit are low, so easy for installation.
This utility model is further arranged to:The door is made using elastomeric material.
By adopting above-mentioned technical proposal, using elastomeric material made by elastomeric material, with certain elastic deformation energy
Power, the requirement to quality of fit are low, so easy for installation.
This utility model is further arranged to:The rubber ring is provided with inward flange and outward flange, inward flange and outward flange
Annular bayonet socket is formed, annular bayonet socket snaps in the lower end of plastic tube.
Can quickly be set on reinforcing bar and pacify by interface arrangment by adopting above-mentioned technical proposal, such rubber ring
The lower end of plastic tube is attached to, it is easy for installation.
This utility model is further arranged to:The diapire of the door has extended downwardly annular ridge, the side wall of door and
Annular ridge forms caulking groove, the upper end of the embedded plastic tube of caulking groove.
By adopting above-mentioned technical proposal, door more solid can effectively be connected to plastic tube upper end, sealability, anti-
Exfoliation ability is more preferable.
This utility model is further arranged to:The sealing member adopts the upper and lower end of adhesive tape, plastic tube to use adhesive tape circumvolution
Sealing.
By adopting above-mentioned technical proposal, just can be close by plastic tube in a few circles of upper and lower end circumvolution of plastic tube using adhesive tape
Envelope, it is without the need for specially remanufacturing sealing member, cost-effective.
This utility model is further arranged to:The demarcation strip is made using sheet metal.
Batch machining is easier by adopting above-mentioned technical proposal, sheet metal, while it is more smooth to compare its surface of plank,
It is worse with the cementability of concrete so as to abolish pile crown more laborsaving.
In sum, this utility model has the advantages that:First it is arranged on reinforcing bar is above the ground level the part of benchmark
Then the opening of plastic tube upper end and lower end and the clearance seal of reinforcing bar are so poured coagulation using sealing member by plastic tube
After soil, concrete and rebar will not be contacted, and there is no bonding relation between the two.
Simultaneously the concrete on pile crown is split by demarcation strip again so that this part concrete caking property of itself is entered
One step is reduced.When abolishing pile crown, staff only needs to the bonding relation for abolishing concrete itself, and without the need for as in prior art
The bonding relation destroyed between concrete itself and concrete and rebar simultaneously, compared to existing technology, the underground of the design
The pile crown of diaphragm wall is easy to be abolished.
