The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1 to 3, the prefabricated assembly type rainwater and sewage drainage common ditch of the present embodiment includes a prefabricated drainage ditch main body 10 and a prefabricated interlayer cover plate 20, the drainage ditch main body 10 is opened upwards, and includes two side walls 11 arranged oppositely and a bottom plate 12 connecting bottom ends of the two side walls 11, convex supporting flanges 13 are formed on opposite side surfaces of the two side walls 11, as shown in fig. 3, the supporting flange 13 on the left side wall 11 protrudes to the right side, the supporting flange 13 on the right side wall 11 protrudes to the left side, two side edges of the interlayer cover plate 20 are correspondingly lapped on the supporting flange 13, and the interlayer cover plate 20 separates an inner space of the drainage ditch main body 10 into a sewage runner 30 located below the interlayer cover plate 20 and a rainwater runner 40 located above the interlayer cover plate 20.
The sewage flow groove 30 is arranged below, the sewage flow groove 30 is arranged above, sewage in dry seasons is discharged in the sewage flow groove 30 below, and the upper part of the sewage flow groove is separated from the rainwater flow groove 40 of the open ditch above through the interlayer cover plate 20, so that the emission of sewage odor is reduced; the two sides of the interlayer cover plate 20 are lapped on the corresponding supporting convex edges 13, so that the assembly and the daily opening of the interlayer cover plate 20 are convenient for overhauling the sewage launder 30.
Specifically, the drainage ditch body 10 is of an integral structure, and is integrally precast and poured by reinforced concrete, that is, the side walls 11 and the bottom plate 12 are integrally cast, and the interlayer cover plate 20 is also precast and poured by reinforced concrete, and the width of the interlayer cover plate is slightly smaller than the distance between the two opposite side surfaces of the two side walls 11, so that the interlayer cover plate can be smoothly placed into the drainage ditch body 10 from top to bottom and is lapped on the supporting convex edges 13 at the two sides. The top surfaces of the supporting convex edges 13 on the two side walls 11 are located on the same horizontal plane, and the interlayer cover plate 20 is a rectangular cover plate, and is in plane contact with the supporting convex edges 13 on the two sides, so that the top surface of the interlayer cover plate 20 is ensured to be horizontal, the interlayer cover plate 20 is stable, and the bottom of the rainwater flow groove 40 is prevented from being polluted.
Further, as shown in fig. 3, an arc-shaped groove 14 is formed on the top surface of the bottom plate 12, and the arc-shaped groove 14 forms the bottom of the sewage flow tank 30, i.e., the bottom of the sewage flow tank 30 is arc-shaped. The profile of the arc-shaped groove 40 is approximately semicircular without dead angles so as to avoid the deposition of sewage impurities as much as possible.
Because the impurity is more in the sewage, if sewage chute 30 surface is too coarse, can reduce sewage velocity of flow, leads to impurity easily to deposit, for solving this problem, in some embodiments of this application, can pre-buried arc PVC pipeline in the bottom plate 12, arc PVC pipeline and arc recess 14 looks adaptation. Specifically, the arc PVC pipeline is located arc recess 14 department, and its inner wall exposes, and the inner wall of PVC pipeline is smooth, improves sewage velocity of flow, is favorable to preventing sewage impurity and deposits.
Since the common drainage ditch is usually long, in order to facilitate prefabrication and field assembly, as shown in fig. 1 and 2, the main drainage ditch 10 of this embodiment is formed by connecting a plurality of sub-ditch bodies 15 in sequence (i.e. along the length direction of the common drainage ditch), and in order to prevent water leakage along the connecting seam, in two adjacent sub-ditch bodies 15, the end parts of the side walls 11 of one sub-ditch body 15 are lapped on the end part of the bottom plate 12 of the other sub-ditch body 15, i.e. in a staggered lapping mode, the flow path of the water leakage is blocked. Specifically, in two adjacent sub-groove bodies 15, the bottom end of the sidewall 11 of one sub-groove body 15 has a sidewall convex edge 11A, and the top end of the bottom plate 12 of the other sub-groove body 15 has a bottom plate convex edge 12A, and when overlapping, the sidewall convex edge 11A is located on the bottom plate convex edge 12A, as shown in fig. 2. Each sub-ditch body 15 is correspondingly small in size, so that prefabrication and field assembly are facilitated, and the corresponding pouring mold is small in size and low in cost.
In some embodiments of the present application, a sealing component 50, such as a rubber gasket or a silica gel pad, is disposed between the supporting flange 13 and the interlayer cover plate 20, which is beneficial to sealing between the rainwater channel 40 and the sewage channel 30, so as to prevent a large amount of rainwater from entering the sewage channel 30 in the lower part in rainy season, and to seal the sewage channel 30 in the western region, so as to achieve sewage arrangement, reduce odor emission, and improve living environment of rural residents.
Also for the convenience of prefabrication and on-site assembly, as shown in fig. 1, the partition cover plate 20 is formed by connecting a plurality of sub cover plates 21 in sequence (i.e. along the length direction of the drainage common ditch), and in two adjacent sub cover plates 21, the end part of one sub cover plate 21 is overlapped on the end part of the other sub cover plate, i.e. the overlapping mode of the staggered stubble is also adopted, so that rainwater is prevented from leaking downwards along the seam as much as possible. Each sub-cover plate 21 is correspondingly small in size, so that prefabrication and field assembly are facilitated, the corresponding pouring mold is small in size, and the cost is low.
Further, as shown in fig. 4 and 5, in two adjacent sub-cover plates 21, a snap 21A is formed at the overlapping position of the end of one sub-cover plate 21, and a snap 21B is formed at the overlapping position of the end of the other sub-cover plate 21, and the snap 21A and the snap 21B are fastened to connect the two adjacent sub-cover plates 21 to each other, so that the sealing effect can be improved, and rainwater in the rainwater tank 40 at the upper part of rainy season can be prevented from seeping through the gap between the two adjacent sub-cover plates 21.
The top surface of the partial sub-cover plate 21 is provided with lifting lugs 21C, the sub-cover plate 21 provided with the lifting lugs 21C is installed at a certain interval and is used for maintenance and maintenance management of the later-stage lower-layer sewage runner 30, and the lifting lugs 21C can be made of steel bars.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
