Detailed Description
The present invention will be further described with reference to the structures or terms used herein. The description is given for the sake of example only, to illustrate how the utility model may be implemented, and does not constitute any limitation on the utility model.
As shown in fig. 1-5, a cover plate fixing structure for the sewage treatment field comprises an outlet channel 1, cover plates 2 and supporting angle irons 3, wherein a groove 11 is formed in the top wall of the outlet channel, part of the supporting angle irons 3 are pre-arranged in the groove 11, and part of the supporting angle irons are pre-buried in the wall of the outlet channel, a plurality of cover plates 2 span over the outlet channel 1 at equal intervals, two sides of each cover plate 2 are in contact with the supporting angle irons 3, adjacent cover plates 2 are fixed through T-shaped auxiliary pieces 4, each T-shaped auxiliary piece 4 comprises a horizontal block 41 and a vertical block 42, the horizontal block 41 is parallel to the horizontal direction of the cover plate 2, the vertical block 42 is positioned between the adjacent cover plates 2, and the T-shaped auxiliary pieces 4 are fixed on the supporting angle irons 3.
The T-shaped auxiliary pieces 4 are arranged to prevent the cover plates 2 from moving in the front-back direction and the left-right direction on the basis that the adjacent cover plates 2 keep a certain distance. Meanwhile, the damage of the surface anti-corrosion paint caused by welding of the cover plate 2 is avoided, the service life of the cover plate 2 is prolonged, and the production cost is reduced.
As a specific example, the horizontal block 41 includes a first horizontal contact surface 411 and a second horizontal contact surface 412, the vertical block 42 includes a first vertical contact surface 421 and a second vertical contact surface 422, the first horizontal contact surface 411 is attached to a horizontal end surface of an adjacent cover plate, and the first vertical contact surface 421 is attached to a vertical end surface of the cover plate; the second horizontal contact surface 412 is attached to the horizontal end surface of another adjacent cover plate, and the second vertical contact surface 422 is attached to the vertical end surface of the cover plate. Therefore, two adjacent cover plates 2 are tightly attached to the T-shaped auxiliary part 4, and the cover plates 2 are effectively prevented from moving.
As a specific example, the horizontal block 41 has a length of 40mm, a width of 8mm and a thickness of 20 mm; the vertical block 42 is 20mm long, 50mm wide and 20mm thick. The size of the T-shaped auxiliary member 4 is not limited to the above, and is determined according to the design requirements.
As a specific example, the T-shaped auxiliary 4 is welded to the support angle 3. The welding mode is simple to operate and the welding is firm.
As a specific example, T-shaped auxiliary members 4 are provided on both sides of the adjacent cover plates. Namely, two T-shaped auxiliary parts 4 are respectively arranged at two sides of the water outlet channel, so that two adjacent cover plates 2 are tightly attached to the T-shaped auxiliary parts 4, and the cover plates 2 are ensured not to move.
As a specific example, the top of the cover plate 2 is flush with the top of the recess 11. Filter brick is placed to 2 tops on the apron, just can't interlock each other if the difference of height filter brick, leads to the filter brick displacement easily, and the filter material will run off downwards for a long time, influences the filter effect.
As a specific example, the cover plate 2 is 2cm thick. The cover plate is not too thin and one of the functions of the cover plate 2 is to support the filter bricks, thus having a certain thickness and meeting the strength requirement. Meanwhile, the cover plate 2 is not too thick, and the cost is saved.
As a specific example, the width of the groove 11 is 8-10 cm. The width of the groove is such that the horizontal blocks of the T-shaped auxiliary element 4 are all located in the groove 11.
The installation process of apron does: support angle bar 3 part and bury in going out the canal wall in advance, partly in recess 11 in advance, with apron 2 lid on supporting angle bar 3, adjacent apron passes through T type auxiliary member 4 fastening, and apron 2 is laid and is accomplished, welds T type auxiliary member 4 on supporting angle bar 3.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
