DETAILED DESCRIPTION OF THE INVENTION

(9) FIG. 3 discloses the quick-fit self-priming drain pipe (100), comprising at least two pipes (1) and at least a joint pipe (2). The pipe body (1) is a hard pipe as shown in FIG. 1, e.g. rigid plastics or metal materials, formed in one, its surface is surrounded with several endlong extended slots (11) in the axial direction of the pipe body (1), from the end face of the pipe body (1), as shown in FIG. 1a, the slot (11) comprises a groove (111) and a narrow slit (112) connecting the inside diameter of the groove (111) to the outer side of the pipe body (1) from inside to outside. The outer surface at the ends of the pipe body (1) is surrounded with several positioning holes (12). The joint pipe (2), as shown in FIG. 2, can be connected to the pipe body (1), and it has at least two ports (21) corresponding to one end of the pipe body (1), and its inner surface is surrounded with several locating pieces (22) corresponding to the positioning holes (12).

(10) The present invention only requires several trenches in the land, the pipe body (1) is fitted with the joint pipe (2) and placed in the trench and covered with soil, the overall process is simple, the working efficiency is increased greatly. The pipe body (1) is designed as hard pipe, the structural strength is enhanced, it will not be deformed under the pressure of soil cover, the slot (11) formed of groove (111) and slit (112) can collect and discharge water after landfill.

(11) In terms of the connection mode of the pipe body (1) and joint pipe (2) of the present invention, two pipes (1) can be connected to a joint pipe (2), and multiple pipes (1) can be connected to multiple joint pipes (2) to form a long pipe. The inner surface of joint pipe (2) is provided with several locating pieces (22), which are tenoned in the positioning holes (12) of pipe body (1), so that they can be fastened firmly.

(12) After the pipe body (1) is connected to the joint pipe (2), the drainage pattern is shown in FIG. 4, the water in soil flows into the slots (11) on the surface of pipe body (1), and into the trench holes (111) through the slit (112), the height difference makes the water flows to the low end of pipe body (1). When the water flows to the joint pipe (2), the water collected in the trench holes (111) flows from the low end of pipe body (1) into another pipe body (1), so that the water is discharged from another low end of pipe body (1).

(13) FIG. 5 shows another implementation pattern of joint pipe (2), there are tensioning slots (23) on both sides of the positioning member (22) at the end of port (21), when the pipe body (1) and joint pipe (2) are assembled as shown in FIG. 6, when one end of pipe body (1) passes through the through hole (11) and contacts the positioning member (22), the outside diameter of through hole (11) is forced to expand outwards, when the positioning hole (12) of pipe body (1) corresponds to the positioning member (22), they are clipped, as shown in FIG. 7. In addition, the circumference of one end of pipe body (1) can be chamfered, the pipe body (1) is easy to pass through the through hole (11) for its convergent end, it is favorable for assembly, and the assembly time is shortened greatly, the time cost is reduced.

(14) As shown in FIGS. 5-6, the inner surface of the joint pipe (2) is provided with several stop pieces (24) for propping the end face of the pipe body (1) after the pipe body (1) is inserted in the port (21). They keep the end faces of two pipes (1) away from each other at an appropriate distance without reducing the draining efficiency of slots (11), so that the water on the surface of pipe body (1) can flow into the pipe.

(15) The end face of the positioning member (22) facing the inside of the joint pipe (2) is a bevel face or an arc face. In the case of bevel face, the slots (11) are free from the blocking of locating pieces (22), the height difference makes the water flows through the positioning holes (12) into the pipe body (1). In the case of arc face, the water can flow into the pipe body (1).

(16) The sectional form of the pipe body (1) is one of the following shapes, circle, square and polygon, so the implementation is not limited to the circle shown in the figures.
