Abstract
The utility model relates to a kind of diaphragm wall seam grouting device, grouting device is made up of two floral tubes, Dense mesh screen and Duo Gen steel pipe, two floral tubes are laterally communicated with many steel pipes, two floral tubes are respectively with after Dense mesh screen parcel, be welded in diaphragm wall reinforcing cage two side seams in advance, if later stage diaphragm wall seam crossing generation seepage, two floral tubes of grouting device can be directly utilized to carry out two fluid grouting leak stopping; If there is not seepage, then with two floral tubes of cement paste shutoff grouting device.The utility model has the advantage that treatment effeciency is high, expense is low, and is carry out leak stopping, Be very effective from body of wall inside, effectively can solve the leakage problems of diaphragm wall seam crossing.
Description
Technical field:
The utility model belongs to the realm of building construction, relates generally to diaphragm wall seam grouting device, is applicable to diaphragm wall.
Background technology:
In huge ultradeep foundation pit engineering, the construction quality of diaphragm wall, is related to the progress of soil excavation, and due to the underground soil property of complexity and hydrological environment, diaphragm wall there will be unavoidably leak, the phenomenon such as quicksand, especially at diaphragm wall seam crossing, the maximum probability had an accident.Existing sealing leaking-stopping measure is: arrange H profile steel in reinforcing cage both sides, and two width reinforcing cage seam crossings can have occlusion to a certain degree, reduces the phenomenon of seepage.
Because the concreting of H profile steel both sides has sequencing, first have a small amount of concrete along concentrated flow to H profile steel opposite side as region, when brush wall device cleaning foreign material are incomplete, still have water along seam crossing to seepage in hole.
Summary of the invention:
The utility model is the shortcoming and defect existed to make up prior art, a kind of diaphragm wall seam grouting device is provided, the utility model is without the need to too much input, shutoff fast can be carried out in time after there is seepage, and owing to being from the inner slip casting of body of wall, plugging effect is remarkable, also effectively can control later stage diaphragm wall seam and occur the impact of seepage on subsequent construction.
The technical scheme that the utility model realizes is:
A kind of diaphragm wall seam grouting device, be made up of two floral tubes, Dense mesh screen and Duo Gen steel pipe, it is characterized in that: two floral tubes are laterally communicated with many steel pipes, two floral tubes, respectively with after Dense mesh screen parcel, are welded in diaphragm wall reinforcing cage two side seams in advance.
Described floral tube is opened injected hole by DN48*3 steel pipe and is made, and injected hole is that plum blossom-shaped is arranged along steel pipe total length, spacing 400mm, aperture 4-6mm.
After described floral tube is welded in diaphragm wall in advance, floral tube top mark exceeds diaphragm wall reinforcing cage top mark height 200mm, absolute altitude at the bottom of floral tube low go out absolute altitude 2000mm at the bottom of foundation ditch, and bottom shutoff.
Two floral tubes, at a distance of 250mm, are communicated with spacing 2000mm transverse weld with DN20*3 steel pipe.
Utilize the construction method of above-mentioned diaphragm wall seam grouting device, it is characterized in that carrying out according to the following steps: when making diaphragm wall reinforcing cage, grouting device is welded in reinforcing cage both sides in advance, if later stage diaphragm wall seam crossing generation seepage, directly utilizes two floral tubes to carry out two fluid grouting leak stopping; If there is not seepage, then use cement paste shutoff two floral tubes.
Grouting device of the present utility model is fixed on diaphragm wall reinforcing cage both sides in advance, and when seepage appears in diaphragm wall seam crossing, can carry out two fluid grouting by two of a grouting device floral tube in body of wall, effective sealing leak stopping is carried out at butt joint position; If there is not seepage, then use cement paste shutoff two floral tubes.The utility model can process leakage problems fast, and Be very effective, expense are low.
Accompanying drawing illustrates:
Floral tube network for location when Fig. 1 is the utility model use.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, device of the present utility model is made up of two floral tubes 1, Dense mesh screen 2 and Duo Gen steel pipe 3, it is characterized in that: two floral tubes 1 are laterally communicated with many steel pipes 3, after two floral tubes 1 wrap up with Dense mesh screen 2 respectively, be welded in diaphragm wall reinforcing cage two side seams in advance.
Construction method is carried out according to the following steps: when diaphragm wall fabrication of reinforcing cage, grouting device of the present utility model is embedded in advance diaphragm wall reinforcing cage two side seams, when there is seepage in diaphragm wall seam crossing, can carry out two fluid grouting by two of a grouting device floral tube 1 in body of wall, effective sealing leak stopping is carried out at butt joint position.
As shown in Figure 2, in the utility model the making of grouting device and use procedure as follows
1, grouting device makes requirement
Floral tube leaves injected hole by DN48*3 steel pipe and is made, and injected hole is that plum blossom-shaped is arranged along steel pipe total length, spacing 400mm, aperture 4-6mm, and floral tube external application Dense mesh screen wraps up; Two floral tubes, at a distance of 250mm, are communicated with spacing 2000mm transverse weld with DN20*3 steel pipe.Floral tube length is determined according to absolute altitude, and after described floral tube is embedded in diaphragm wall in advance, floral tube top mark exceeds diaphragm wall reinforcing cage top mark height 200mm, absolute altitude at the bottom of floral tube low go out absolute altitude 2000mm at the bottom of foundation ditch, and bottom shutoff.
2, pre-buried grouting device
Grouting device bar dowel is fixedly welded on inside diaphragm wall reinforcing cage, divides into together with reinforcing cage, then builds diaphragm wall concrete.
3, floral tube is anti-blocking
Consider that having a small amount of cement paste when diaphragm wall concreting infiltrates floral tube, may block floral tube, therefore, before concreting, pipe domestic demand fills clear water, sinks at the bottom of pipe after can ensureing to allow cement paste be diluted by clear water.
4, blocking method
In subsequent construction, if the phenomenon of seam crossing seepage appears in diaphragm wall, can carry out two fluid grouting by floral tube, effective sealing leak stopping is carried out at butt joint position;
If there is not seepage, then use cement paste shutoff floral tube.
