Description
Technical field
The utility model belongs to valve body technical field, is specifically related to a kind of concrete safety check.
Background technique
CFST Arch Bridge concrete-filled steel tube arch is a kind of structural type belonging to concrete filled steel tube, it concrete is poured in steel tube arch rib make steel pipe and concrete acting in conjunction, strengthen the strength and stiffness of structure, there is form grace, span is large, easy construction, antidetonation, resistance to compression, feature that cracking resistance is high.During steel-pipe concrete arch construction, arch springing often adopts at reserved the second stage of abut concrete, first steel tube arch rib is installed, and build the second stage of abut concrete, consolidation is carried out to steel tube arch rib, then mouth is watered locating respectively to open a concrete identical with concrete pumping line diameter at steel tube arch rib two ends apart from abut about 1 ~ 2m, then from the bottom upwards symmetrical jacking concreting of steel tube arch rib, water Man Houzai concrete to be watered mouth place and close, perfusing hole after the final set of steel tube arch rib concrete on welded closure steel tube arch rib, forms steel tube arch rib and the cooperative composite structure of pipe inner concrete.For preventing the concrete backflow when concrete delivery pipe is removed, need backflow valve being set bottom arch rib, just can preventing concrete from refluxing.
Summary of the invention
Problem to be solved in the utility model is to overcome concrete filled steel tube and pours and reflux and prevent spillage in concrete pumping jacking process from causing the shortcoming of plugging, provide a kind of reasonable in design, good sealing effect, structure simple, the flat concrete safety check of low-cost high-efficiency.
Solving the problems of the technologies described above adopted technological scheme is: one end of pump line connecting tube is provided with right flange plate, right flange plate is processed with through hole a, one end of steel pipe connecting adapter is provided with left flange plate, left flange plate is processed with through hole b, check valve plate is provided with between right flange plate and left flange plate, check valve plate is processed with through hole c, pump line connecting tube and steel pipe connecting are taken over and are connected, between right flange plate and check valve plate, on right flange plate, the arranged outside of through hole a has right seal ring, between left flange plate and check valve plate, on left flange plate, the arranged outside of through hole b has left seal ring.
The internal diameter that the aperture of the internal diameter of pump line connecting tube of the present utility model and the aperture of through hole a, through hole b, the aperture of through hole c, steel pipe connecting are taken over is equal, and the center line that the center line of the center line of pump line connecting tube and the center line of through hole a, through hole b, the center line of through hole c, steel pipe connecting are taken over overlaps.
In the middle part of check valve plate of the present utility model along its length on be evenly distributed with 3 screws, through hole c is between adjacent two screws.
The utility model adopts at right flange plate and arranges seal ring between left flange plate and check valve plate; improve valve seal; prevent from overflowing from the gap between left and right flanges dish and check valve plate in concrete slurry pumping jacking process and cause plugging and affect concrete pumping continuity constructing; and protect valve body; improve the working life of valve body, the utility model has that structure is simple, sealing effect is good, easy to operate, working efficiency is high, the advantage of long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to following mode of execution.
Embodiment 1
In FIG, the flat concrete safety check of the present embodiment is by pump line connecting tube 1, right flange plate 2, check valve plate 3, left flange plate 4, steel pipe connecting adapter 5, left seal ring 6, right seal ring 7 connects and composes, one end outer wall that pump line connecting tube 1 connects pump line is along the circumferential direction processed with groove, for connecting with pump line, the other end of pump line connecting tube 1 is welded with right flange plate 2, the center of right flange plate 2 is processed with through hole a, the aperture of through hole a is equal with the internal diameter of pump line connecting tube 1, the center line of through hole a overlaps with the center line of pump line connecting tube 1, on the right side of right flange plate 2, the outside of through hole a is processed with circular groove, right seal ring 7 is installed in circular groove, one end of steel pipe connecting adapter 5 is welded with left flange plate 4, the center of left flange plate 4 is processed with through hole b, the aperture of through hole b is identical with the internal diameter of steel pipe connecting adapter 5, the center line of through hole b overlaps with the center line of steel pipe connecting adapter 5, on the left side of steel pipe connecting adapter 5, the outside of through hole b is processed with circular groove, left seal ring 6 is installed in circular groove, between right flange plate 2 and left flange plate 4, check valve plate 3 is installed, the geometrical shape of check valve plate 3 is rectangular slab, check valve plate 3 center line along its length is evenly processed with 3 screws, through hole c is processed with between side two screw of check valve plate 3, the aperture of through hole c is identical with the aperture of through hole b with through hole a, the center line of through hole c overlaps with the center line of through hole a and through hole b, right flange plate 2 and left flange plate 4 and check valve plate 3 are fixedly connected by screw threads for fastening coupling.
Check valve plate of the present utility model can ensure that when concreting concrete passes through smoothly, after having built, unclamp bolt fixing on left flange disc 4 and right flange plate 2 and check valve plate 3, move down check valve plate 3, through hole c on check valve plate 3 and right flange plate 2 through hole a and left flange plate 4 through hole b is misplaced, again the bolt on fastening left flange disc 4 and right flange plate 2 and check valve plate 3, effectively stops concrete backflow.Concrete reflux problem when the utility model solves concreting in Large-diameter Steel tubing string preferably, ensure that the concrete degree of compaction of tubular arch, thus ensures the integral construction quality of steel core concrete column, and reduce concrete backflow wastes simultaneously; There is volume little, lightweight, good seal, simple and quick, the application requirement of different amount position can be met in different work progress, uses manpower and material resources sparingly, the feature such as fixed.
