Description
Technical field
The utility model belongs to architecture construction technical field, and in particular to a kind of water-stopping steel sheet pile.
Background technique
Steel sheet pile is a kind of hot-rolled steel section with fore shaft, and there are straight panel shape, flute profile and Z-shaped etc. in section, there is all size ruler
Very little and interlocking form.It common are Ademilson formula of drawing, Lackawanna type etc..It is connected with each other and is engaged by fore shaft, form continuous steel plate
Piling wall is used to earth-retaining and water blocking；Its advantage are as follows: intensity is high, is easy to squeeze into hard soil layer；Can in deep subaqueous work, when necessary plus
Bearing diagonal becomes an inclosure.Waterproof performance is good；The cofferdam of various shapes can be formed as needed, and can be repeatedly used, because
This, it widely used.
But there are fore shafts between two pieces of steel sheet piles, bending deformation, Sloped rotating after steel sheet pile injection will lead to steel plate
Stake leakage.
To solve steel sheet pile fore shaft seepy question, have following two major classes method at present: a kind of way is in steel sheet pile fore shaft
It is inside coated in advance with sealing material, sealing material is mainly bloating tendency solvent, elastic sealing compound, resinae solvent and dilatancy rubber
Glue etc. is constituted；Or undisturbed soil is replaced with cement bentonite in the position grooving of steel sheet pile pile sinking in advance；It is pre- in steel sheet pile fore shaft position
First drilling, which is changed, fills out cement bentonite；It is changed in advance or after pile sinking near fore shaft and fills out the measures such as dilatancy sealing material progress manual seal
Fore shaft；This method is easy to happen leakage vulnerable to construction infection, and not easy to handle after discovery breakthrough.Another method is in steel
High-pressure rotary jet grouting pile is set after sheet pile or stirring pile water stopping curtain, this method cost are higher.
Summary of the invention
The purpose of this utility model is to provide a kind of structure is simple, at low cost, the higher steel plate for sealing water of sealing reliability
Stake.
Water-stopping steel sheet pile provided by the utility model, the steel sheet pile use market routine Larsen steel sheet pile, steel sheet pile
For strip shape steel plate, section is generally straight panel shape, flute profile and Z-shaped etc., and the fold curling of section both ends forms hook groove shape fore shaft 1；
The fore shaft of steel sheet pile successively links, and forms the steel plate wall of water blocking earth-retaining；
In the fore shaft 1, steel sheet pile length direction is provided with Grouting Pipe 2；And when the fore shaft 1 of two steel sheet piles is mutual
It links, when forming a cavity 3, Grouting Pipe 2 is located in the cavity 3；
The Grouting Pipe 2 is equipped with spaced circumferential cutting mouth 4；The closing of 2 bottom nozzle of Grouting Pipe, top nozzle are set
Set dismountable boring cover 5.
In the utility model, 2 length of Grouting Pipe is greater than steel plate pile length, and 2 top nozzle of Grouting Pipe is higher than steel sheet pile.
In the utility model, the spacing distance of the cutting mouth 4 is 300mm ~ 600mm, preferably 400mm.
In the utility model, the Grouting Pipe 2 is round tube, and the size incision of the cutting mouth 4 is 100 ° ~ 140 °, preferably
120°。
When the utility model is used, Grouting Pipe is fixed in the fore shaft of steel sheet pile, and makes the Grouting Pipe place of cutting open in face of outer
The cavity that side, fore shaft are formed.Construction, several steel sheet piles are connected in turn, are squeezed into ground；Between two steel sheet piles
It is connected by fore shaft, fore shaft hooks together mutually, the bending section of each fore shaft groove is formed to interconnection similar to groove shape
Another fore shaft groove opening portion is blocked, and makes to form cavity among groove and groove, Grouting Pipe is just in cavity.
After excavation of foundation pit, such as find that there is percolating water situation in the fore shaft junction of steel sheet pile, opens the Grouting Pipe at percolating water
Boring cover, in time to carrying out slip casting in Grouting Pipe.In Grouting Pipe when slip casting, since injecting paste material is clay-bentonite slurry,
Under certain pressure effect, it can fill up within a short period of time cavity by being permeated at Grouting Pipe cutting mouth to cavity and solidify, reach
To fore shaft position water-stagnating effect.
Due to construction site environment complexity, steel sheet pile is driven underground by machinery, so will appear some fore shaft deformations
Or soil etc. falls into the situation in the cavity of fore shaft formation；If direct slip casting cavity is not it is possible that slip casting is complete, blocking
Deng.So introduce Grouting Pipe can more preferably more evenly slip casting filling fore shaft formed cavity, reach sealing effect.
The utility model has the advantages of simple structure, at low cost, sealing high reliablity.When steel sheet pile recycling simultaneously, can easily it extract
And replace Grouting Pipe.If the non-leak of steel sheet pile carries out slip casting, Grouting Pipe still can be used after steel sheet pile recycling.
Detailed description of the invention
Fig. 1 is the utility model embodiment overall structure diagram.
Fig. 2 is the utility model knot Grouting Pipe facade structures diagram.
Fig. 3 is that embodiment steel sheet pile is sequentially connected plan structure diagram.
Figure label: 1 is fore shaft, and 2 be Grouting Pipe, and 3 be cavity, and 4 be cutting mouth, and 5 be boring cover.
Specific embodiment
In the utility model, there are straight panel shape, flute profile and Z-shaped etc. in the section of steel sheet pile, there is full range of sizes and interlocking shape
Formula.
U-shaped steel sheet pile is now selected, the fold curling of section both ends forms hook groove shape fore shaft 1, as shown in Figure 1.
The Grouting Pipe 2 uses rubber material, round tube, and circumferential cutting mouth 4 is alongst arranged at Grouting Pipe 2
On；The spacing distance of cutting mouth 4 is 400mm；Cutting mouth 4 is that the sector formed centered on the circular hollow section center of circle intersects with tube wall
Intersecting lens, it is 120 ° that define size incision, which be fan-shaped angle,.
Dismountable boring cover 5 is arranged in 2 bottom nozzle of the Grouting Pipe closing, top nozzle.
The Grouting Pipe 2 is set in fore shaft 1 along steel sheet pile length direction；And when the fore shaft 1 of two steel sheet piles is mutual
It links, when forming a cavity 3, Grouting Pipe 2 is located in the cavity 3.As shown in Figure 3.
The cavity that Grouting Pipe is fixed in the fore shaft of steel sheet pile, and forms the Grouting Pipe place of cutting open in face of outside, fore shaft.
Construction, several steel sheet piles are connected in turn, are squeezed into ground vertically；It is connected between two steel sheet piles by fore shaft,
Fore shaft hooks mutually together similar to groove shape, hooks and forms cavity among slot and hook slot, Grouting Pipe is just in cavity；Foundation pit is opened
After digging, such as find that there is percolating water situation in the fore shaft junction of steel sheet pile, opens the boring cover of the Grouting Pipe at percolating water, in time to note
Slip casting is carried out in slurry pipe.In Grouting Pipe when slip casting, since injecting paste material is clay-bentonite slurry, under certain pressure effect,
It can fill up within a short period of time cavity by being permeated at Grouting Pipe cutting mouth into cavity and solidify, reach fore shaft position and stop
Water effect, while when steel sheet pile recycling, it can easily extract and replace Grouting Pipe.If the non-leak of steel sheet pile carries out slip casting, slip casting
Pipe still can be used after steel sheet pile recycling.
Due to construction site environment complexity, steel sheet pile is driven underground by machinery, so will appear some fore shaft deformations
Or soil etc. falls into the situation in the cavity of fore shaft formation；If direct slip casting cavity is not it is possible that slip casting is complete, blocking
Deng.So introduce Grouting Pipe can more preferably more evenly slip casting filling fore shaft formed cavity, reach sealing effect.
