Shape fixing channel and field all-angle seamless connection method thereof

Abstract

The invention discloses a shape fixing channel and a field all-angle seamless connection method thereof. The channel comprises channel body and concrete turning connectors. The channel body comprises a main channel body, and the two ends of the main channel body are provided with notches and lap joints; the main channel body is of an open type groove structure, and rib plates are arranged on the outer sides of the upper edges of the main channel body; each lap joint comprises outer side surfaces and outer side stand surfaces, the outer side surfaces and the outer side of the main channel body are located on the same plane, and the outer side stand surfaces and the outer side surfaces are inclined by 60 degrees; each notch comprises an inner side surface and inner stand surfaces, the inner side surface is perpendicular to the inner stand surfaces, and the shape and the inner diameter of each notch are matched with the shape and the inner diameter of the corresponding lap joint correspondingly; and during linear connection, rubber water stop belts are arranged inside the notches for lap joint connection through the lap joints, and during turning connection, adhesive connection is performed at the lap joints through the cast-in-place concrete turning connectors. The shape fixing channel and the field all-angle seamless connection method thereof have the advantages that the channel is simple in structure, and turning mounting of one section of main channel body can be achieved at all angles within 30 degrees; and the connection method is simple and convenient, the strength of the connection positions is high, the anti-seepage effect is remarkable, the whole stability of the channel is high, and the application range is wide.

Description

technical field [0001] The invention relates to a hydraulic engineering device, in particular to a shaped channel and a method for seamlessly connecting it at any angle in the field, and belongs to the technical field of agricultural water conservancy facilities. Background technique [0002] Shaped concrete channels have been widely used in the field of farmland irrigation. They are shaped products produced by the factory. The cross-sectional size of the channel is determined according to the needs. Generally, the length is 2m, and the connection is carried out. The current shaped concrete channels have poor connection at the joints and are prone to water leakage. , reducing water utilization. The utility model with the patent No. ZL201420124659.3 discloses a water-saving water conservancy channel prefabricated part, which includes a channel body, a plugging notch and a plugging protrusion. Figure 1a It can be seen that when plugging, the plug protrudes and inserts into th...

Problems solved by technology

Both of the above two technical solutions have the following defects: 1) the insertion groove and the insertion joint are relatively thin, the manufacturing process is difficult, and they are fragile during insertion; 2) the two channels can only be inserted on the same straight line, that is, only Straight insertion, unable to meet the needs when encountering a curve
