Description
Technical field
The present invention relates to a kind of underground engineering foundation ditch construction methods, especially a kind of in equal thickness Soil-cement Wall
The steel case and its construction method of insertion.
Background technique
Soil-cement Wall interpolation H profile steel is more environmentally friendly, reliable in quality a kind of building enclosure in deep foundation pit construction,
With work efficiency height, speed of application is fast, and core material can be partially recycled after construction, with good economic efficiency, in certain depth
Deep foundation pit support in have obvious advantage.But when foundation pit is deeper, general H profile steel rigidity is smaller, will lead to
The deformation of foundation pit is larger, uses be limited under certain environmental conditions, and conventional fashioned iron Soil-cement Wall is circular
The utilization rate in section, section is also relatively low.Due to the presence of problem above, so developing a kind of raising Soil-cement Wall benefit
With rate, not only can compared with deep basal pit using simultaneously but also can reduce foundation pit deformation construction technology it is very necessary.
Summary of the invention
In order to solve the problems, such as to appear above, the present invention is to provide for a kind of square in equal thickness Soil-cement Wall
Shape steel case and construction method improve the water-stagnating effect of wall, reduce foundation pit for improving the wall stiffness of Soil-cement Wall
Deformation reduces the influence to surrounding enviroment, and with good economic efficiency and social benefit.
To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of in equal thickness Soil-cement Wall
Rectangle steel case, including rectangle steel case, junction steel plate, multiple rectangle steel casees are linked into an integrated entity by junction steel plate, and are inserted into cement
In cob wall body, underground cement soil continuous wall body, the envelope structure as foundation pit are formed.
Further, the rectangle steel case is made by welding, and rectangle steel case two sides are respectively welded junction steel plate, wherein one
It is welded with female connector on the junction steel plate of side, is welded with pin end on the junction steel plate of the other side.
Further, between the junction steel plate of the adjacent rectangle steel case by the female connector that is welded on junction steel plate and
Pin end is cooperatively connected, and extends the permeation pathway of underground water by the female, male connector of rectangle steel case, reduces the percolating water of foundation pit.
A kind of construction method using for the rectangle steel case in equal thickness Soil-cement Wall, comprising the following steps:
1) Soil-cement Wall is inserted into rectangle steel case after wall stirs before the deadline;
2) rectangle steel case should keep the verticality of rectangle steel case using in leading truck insertion cement soil wall body in insertion process
With the stationarity of sinking, cope level should be controlled using suspension element at top after rectangle steel case is inserted into predetermined absolute altitude.
3) it is continuously constructed in such a way that female, male connector is connected between rectangle steel case, hole construction must not be jumped, to prevent square
Shape steel case can not be connected effectively.
4) after rectangle steel case is sequentially connected, subsequent construction can be carried out.
Further, the insertion of the rectangle steel case is inserted into cement soil wall body by self weight, when the soil for meeting difficulty
Layer can increase the measure that auxiliary is sunk, but cannot simultaneously be sunk by the way of loose hook falls using hoisting steel case is repeated several times, and prevent
Steel carton deformed and influence verticality.
The beneficial effects of the present invention are:
1. the present invention is connected by continuous steel case, while being inserted into cement soil wall body, forms underground soil cement and connect
Continuous wall has biggish strength and stiffness as the envelope structure of foundation pit, is conducive to foundation pit control deformation.
2. sealing of the invention is mainly to adopt the permeation pathway for extending underground water by the female, male connector of steel case, base is reduced
The percolating water in hole.
3. using the present invention, the available effective promotion of the construction depth of foundation pit, it is possible to reduce the deformation of foundation pit has simultaneously
There is good sealing performance.
To sum up, the wall stiffness of Soil-cement Wall can be improved in the present invention, improves the water-stagnating effect of wall, reduces foundation pit
Deformation, reduce influence to surrounding enviroment, and with good economic efficiency and social benefit.
Detailed description of the invention
Fig. 1 is the rectangle steel case connection schematic diagram in equal thickness Soil-cement Wall;
Fig. 2 is rectangle steel case floor map.
Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of rectangle steel case in equal thickness Soil-cement Wall, by rectangle steel case 2, junction steel plate
3, female connector 5 and pin end 4 etc. form.Multiple rectangle steel casees 2 are linked into an integrated entity by junction steel plate 3, and are inserted into cement soil wall
In body 1, underground cement soil continuous wall body, the envelope structure as foundation pit are formed.Between the junction steel plate 3 of adjacent rectangle steel case
It is cooperatively connected by the female connector 5 and pin end 4 that are welded on junction steel plate 3.Extended by the female, male connector of rectangle steel case 2
The permeation pathway of underground water reduces the percolating water of foundation pit.
As shown in Fig. 2, rectangle steel case 2 is formed in factory process, mainly to be formed by being welded in factory.Rectangle steel case
