Description

Technical Field

[0001] The utility model belongs to the technical field of farmland water channel construction, in particular to an integrated concrete drainage channel for farmland irrigation. Background Art

[0002] Farmland irrigation is introduced into farmland through ditches dug on the ground. The canals are generally dug by hand and can be paved with stone or precast cement slabs to reduce channel water leakage losses and prevent the collapse of the soil side walls on both sides of the channel. This not only saves irrigation water, but also avoids multiple repair operations on the canal in the later stage and prevents secondary salinization of the soil.

[0003] In the prior art, cement prefabricated panels are installed in a single piece, and there is no positioning structure or connection structure between two adjacent cement prefabricated panels. The assembly construction is difficult and the position accuracy is not easy to control. After the assembly of the cement prefabricated panels is completed, the gaps need to be grouted and sealed to improve the anti-seepage performance of the water channel, and the construction operation cycle becomes longer accordingly. Utility Model Content

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] An integrated concrete drainage channel for farmland irrigation comprises a plurality of juxtaposed channel side plates and a channel bottom plate, wherein the middle portion of the channel side plate has a middle hole, and the left and right sides of the channel side plate respectively have semi-open holes, the semi-open hole on the left side of one channel side plate is arranged correspondingly to the semi-open hole on the right side of another adjacent channel side plate, and the middle hole and the semi-open hole both penetrate the height direction of the channel side plate; a connecting screw is fixedly arranged in the channel side plate along its length direction, and both ends of the connecting screw are respectively provided with end external threads with opposite rotation directions, a connecting screw fixedly arranged in one channel side plate is arranged correspondingly to a connecting screw fixedly arranged in another adjacent channel side plate, and the ends of the two connecting screws are fixedly connected by a double-threaded sleeve, and the two ends of the double-threaded sleeve are respectively threadedly connected to the end external threads of the two connecting screw ends.

[0007] As a further improved technical solution of the utility model, both ends of the connecting screw extend into the semi-open hole and do not exceed the left and right sides of the channel side plate, and the connecting screw and the channel side plate are integrally formed by concrete casting.

[0008] As a further improved technical solution of the utility model, the left and right sides of the channel side plate are respectively integrally formed with a rectangular notch and a trapezoidal notch, and a rubber waterstop strip with a trapezoidal cross-section is arranged in the trapezoidal notch. The outer part of the rubber waterstop strip protrudes from the trapezoidal notch, and the outer part of the rubber waterstop strip on the right side of one channel side plate can be pressed into the rectangular notch on the left side of another channel side plate.

[0009] As a further improved technical solution of the utility model, the cross-section of the middle hole is rectangular, the cross-section of the semi-open hole is rectangular, and the semi-open holes on the left and right sides of the two channel side plates are combined to have the same size and shape as the middle hole.

[0010] As a further improved technical solution of the utility model, the concrete cast in the channel side plate is integrally formed with a transverse through hole, and the transverse through hole is arranged along the length direction of the channel side plate. The connecting screw is fitted in the transverse through hole, and the middle part of the connecting screw is provided with two sections of middle external threads, and the two sections of middle external threads are respectively screwed with locking nuts, and the side surfaces of the two locking nuts can respectively press against the inner walls on both sides of the middle hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The concrete drainage channel of the utility model is assembled by splicing the two channel side panels. First, the double-threaded sleeve is screwed to fix the ends of the two connecting screws to achieve the rough positioning of the relative position between the two channel side panels, and then the outer part of the rubber water stop strip on the side of the channel side panel is pressed into the rectangular notch on the side of the other channel side panel. Then, the double-threaded sleeve is continued to be screwed to further reduce the relative position between the two channel side panels until the two are against each other, and it is ensured that the outer part of the rubber water stop strip is completely pressed into the rectangular notch to achieve a better sealing and anti-seepage effect. Therefore, the utility model realizes the rapid positioning and prefabrication of the concrete drainage channel, saves the labor cost of the assembly operation, and further improves the construction quality and shortens the construction period.

[0013] 2. The two channel side plates of the utility model are fixedly connected into one by connecting screws. On the one hand, the overall strength of the concrete drainage channel and the flatness of the channel side walls are improved. The connecting screws can be integrally formed with the channel side plates by concrete casting, or they can be fixedly connected by two locking nuts against the inner walls on both sides of the middle hole. The installation and disassembly are convenient and quick. On the other hand, the channel side plates, connecting screws, rubber water stop strips, locking nuts and double-headed threaded sleeves can be replaced or reused, which greatly saves construction costs and shortens the replacement operation time.
