The utility model discloses adopt the mode that the cross joint plus only starched iron sheet in underground continuous wall width of cloth section seam crossing, cement thick liquid winds to connect the case from both ends when can preventing ground even wall concrete placement behind one's back around pouring concrete around forming, connects the prevention of seepage effectually, has effectively solved the seepage problem that ground even wall connects the universal appearance, and construction reliability is strong, the risk is little.
Description
Technical field
The utility model relates to a kind of anti-seepage flow grouting device of diaphragm wall width section seam crossing.
Background technology
In recent years, super large, ultra-deep foundation pit get more and more, and residing hydrogeological situation also becomes increasingly complex, and according to different designing requirements, different support forms is arranged.Diaphragm wall has that the side direction bending rigidity is large, globality and impervious good, the advantage such as fast of constructing, become the support form of the first-selection of super large foundation ditch, can be used as the double outer wall of basement of doing of supporting and protection structure, in the situation that lower floor's soil property is good, at the bottom of permeability, diaphragm wall has intercepted the contact of inside and outside head, only need in Excavation Process, discharge the hole internal stagnant water, saved the process of precipitation, avoid occurring the generation of the situations such as quicksand, piping, so the problem that is treated as a key of ground-connecting-wall construction width section seam.
The utility model content
The utility model provides a kind of diaphragm wall to prevent seepage flow grouting device, solve that width section seam crossing joint anti-seepage effect is bad, cement grout to adjacent width around the technical problem of filling with.
The utility model solves the technical scheme that its technical problem adopts:
This diaphragm wall is prevented seepage flow grouting device, comprises reinforcing cage, joint, end socket muscle and joint case, and described reinforcing cage both sides are connected with the grouting iron sheet;
Described joint is the cross rigid joint that steel plate for sealing water and end socket steel plate are formed by connecting, and the cross rigid joint is connected in the reinforcing cage end of wall width in advance;
Described end socket muscle is V-arrangement, and the end socket muscle is connected in the reinforcing cage end of rear row wall width;
Described joint case is installed on cross rigid joint dorsal part when the wall width is constructed in advance, and the steel plate for sealing water of cross rigid joint stretches in the groove of joint case.
Described end socket steel plate is connected by angle iron connecting piece I with the grouting iron sheet.
The junction arranged outside of described end socket steel plate and grouting iron sheet has press strip.
Described end socket steel plate is connected by angle iron connecting piece II with the horizontal bar of reinforcing cage.
Described joint case is overall structure, or is formed by connecting vertically by two above steel members.
In described joint case, filler is arranged.
The beneficial effects of the utility model are as follows:
The utility model adopts the mode of the additional grouting iron sheet of cruciform joint at diaphragm wall width section seam crossing, efficiently solve the seepage problem that the ground-connecting-wall joint generally occurs, this technology has following advantage: 1, impervious effective
Rigid joint is cross, at the steel plate for sealing water of seam crossing, stretches out 250mm, has extended the percolation path of underground water, greatly increases the groundwater seepage difficulty, the joint good seepage-proof property.
2, the anti-side seepage of grouting iron sheet
By the grouting iron sheet is installed in the reinforcing cage both sides, along with concrete, build, due to the flexibility of grouting iron sheet, after expanding under pressure, large deformation has held out against sidewall, the adjacent width of constructing backward while having stoped concreting around filling, guaranteed the joint waterproofing requirement.The protective layer thickness of ground-connecting-wall reaches 70mm, and the protection of joint case is arranged, and under powerful lateral pressure, the grouting iron sheet can not crushed.
3, the joint case rises and pulls out easily
After the lifting reinforcing cage, at the dorsal part of end socket steel plate, increase the joint case, to playing anti-seepage flow and steel plate for sealing water, played effective protective effect, can together with steel plate for sealing water, bear the lateral pressure of placing of concrete to the outside, termination.300mm～500mm at the bottom of joint case insertion groove, can prevent that the bottom concrete from flowing into the adjacent slot section, causes follow-up adjacent slot section excavation difficulty.With circular locking notch pipe difference, be, because the end socket steel plate is isolated concrete and joint case mutually, joint case discord concrete is directly contacted, and both sides welderings grouting iron sheet on reinforcing cage, in the time of can preventing ground-connecting-wall concreting cement grout from two ends around to the joint case behind to form around filling with concrete.This joint pulling force is much smaller, and joint quality can guarantee, construction reliability is strong, risk is little.
