Abstract
The utility model discloses a water sealing device between steel cofferdams and concrete, and relates to a water sealing device for bridge foundation construction. The water sealing device comprises water seal rings, which are hermetically fixed on an inner wall of the steel cofferdams, are positioned within height of the bottom concrete, and are closed rings along the inner wall of the steel cofferdams. The water sealing device can be used between large steel cofferdams/steel hanging boxes and the bottom concrete, so as to prevent water seepage between the steel cofferdams and the bottom concrete.
Description
Technical field
The utility model relates to a kind of antipriming of bridge foundation construction, is applicable to the sealing construction between heavy steel cofferdam or steel box and bottom concrete.
Background technology
Steel cofferdam or steel box are works important in the bridge foundation.Steel cofferdam is built bottom concrete after sinking to the absolute altitude and position of appointment in steel cofferdam.After bottom concrete is fixed, in steel cofferdam, form dry construction condition, in the construction of carrying out the subsequent handlings such as cushion cap reinforcing bar binding, concreting.
After in steel cofferdam, building bottom concrete, often because steel cofferdam is different works with bottom concrete, uncertain different with both the temperature shrinkage ratio of size of adhesion stress between the two, tend to form the slit between steel cofferdam and the bottom concrete, phenomenon appears leaking and seeping water, and shown in Figure 1 such as accompanying drawing.In addition because steel cofferdam structure is subjected to current etc. to affect the phenomenon that can occur rocking in water.Rock the slit that can cause between steel cofferdam and the bottom concrete and further increase, infiltration phenomenon between the two is aggravation further.Cause the cushion cap dry construction condition of design to realize, bearing platform construction quality and personnel's job safety are caused adverse effect.
The utility model content
The purpose of this utility model is: propose the antipriming between a kind of heavy steel cofferdam or steel box and bottom concrete, so that do not seep water between steel cofferdam and the bottom concrete.
The purpose of this utility model realizes by following technical proposals:
Antipriming between a kind of steel cofferdam and concrete comprises being sealingly fastened in the steel cofferdam inwall and being positioned at the bottom concrete height, becomes the seal ring of closed hoop along inwall.
As optimal way, described seal ring is connected and fixed from beginning to end by some angle steel and forms.
As optimal way, described seal ring is connected and fixed from beginning to end by some "T"-shaped steel plates and forms.
Working method of the present utility model: add man-hour at steel cofferdam, in steel cofferdam inwall bottom concrete height, add whole circle and end dihedral or "T"-shaped steel plate for sealing water.Bottom concrete build finish after, the seal ring by the steel cofferdam inwall increases has increased the cementation of steel cofferdam and bottom concrete.Newly-increased seal ring and bottom concrete have formed extremely strong interlock, substantially do not have the slit that can seep water between steel cofferdam and the bottom concrete, reach impermeable purpose between steel cofferdam and the bottom concrete.
The beneficial effects of the utility model: blocked the penetrating passage between steel cofferdam and the bottom concrete, greatly improvement effect has been played in the infiltration between steel cofferdam and bottom concrete, reached preferably stagnant water effect.For bearing platform construction has been created well dry construction condition.
Description of drawings
Fig. 1 is the schematic diagram of prior art;
Fig. 2 is the antipriming mounting plane schematic diagram of the utility model embodiment;
Fig. 3 is the antipriming installation site elevation of the utility model embodiment;
Among the figure, 1 is steel cofferdam, and 2 is bottom concrete, and 3 is seal ring, and 31 is angle steel, and 32 is "T"-shaped steel plate.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Shown in Fig. 2,3, the antipriming between a kind of steel cofferdam and concrete comprises being sealingly fastened in steel cofferdam 1 inwall and being positioned at bottom concrete 2 height, becomes the seal ring 3 of closed hoop along inwall.Seal ring 3 has two circles, and a circle seal ring 3 is connected and fixed by some angle steel 31 head and the tail and forms.Another circle seal ring 3 is connected and fixed by some "T"-shaped steel plate 32 head and the tail and forms.
Working method of the present utility model: add man-hour at steel cofferdam, in steel cofferdam 1 inwall bottom concrete 2 altitude ranges, add whole circle angle steel or "T"-shaped steel plate device.According to the needs of bottom concrete height and antiseepage, determine that one encloses or a few.Steel plate for sealing water is fixed by welding and steel cofferdam 1 inwall, and weld should be closely knit, can not seep water.
Bottom concrete build finish after, by the seal ring 3 that steel cofferdam 1 inwall increases, increased the cementation of steel cofferdam 1 with bottom concrete 2.Newly-increased seal ring 3 has formed extremely strong interlock with bottom concrete 2, has blocked the penetrating passage between steel cofferdam 1 and the bottom concrete 2, does not substantially have the slit that can seep water between steel cofferdam 1 and the bottom concrete 2.Even steel cofferdam 1 is rocked by water currents, can not form the penetrating passage between steel cofferdam 1 and the bottom concrete 2 yet, reached preferably stagnant water effect.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
1. the antipriming between a steel cofferdam and concrete is characterized in that: comprise being sealingly fastened in the steel cofferdam inwall and being positioned at the bottom concrete height, become the seal ring of closed hoop along inwall.
