Technical Field

[0001] The utility model relates to the technical field of slope drain pipes, in particular to a slope drain pipe. Background Technique

[0002] A slope drain pipe is a facility used for draining water on a slope. Its principle is to guide the accumulated water inside the slope through the drain pipe, reducing the accumulation of groundwater. This can reduce the water pressure inside the slope and the infiltration and extrusion force of groundwater on the slope. The existing patent (application number: CN202322193000.5) discloses a slope drain hole device, including a drain pipe, a limiting mechanism, and a filter capsule bag. The end cross-section of the inlet end of the drain pipe is Z-shaped. The filter capsule bag is arranged inside the drain pipe and is located at the inlet end of the drain pipe. The limiting mechanism penetrates through the drain pipe, and the limiting mechanism abuts against the end of the filter capsule bag. The inlet end of the drain pipe is connected to the slope soil body. The utility model adopts a Z-shaped end design; during the process of burying the drain pipe into the slope, it is often that the constructor inserts the drain pipe into the slope while winding the geotextile filter layer onto the surface of the drain pipe, making the operation process very troublesome and laborious for the constructor. Therefore, in view of the above problems, the applicant provides a slope drain pipe. Content of the Utility Model

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A slope drain pipe includes a pressing strip, the pressing strip is pressed against the circumferential outer wall of the geotextile filter layer cylinder, and the inner diameter of the geotextile filter layer cylinder is processed to be 1 mm larger than the outer diameters of the first drain pipe and the second drain pipe, making it convenient for manual wrapping around the first drain pipe and the second drain pipe. Threaded hole three is opened on the pressing strip, and a positioning bolt is threadedly connected to the threaded hole three.

[0006] Preferably, it further includes a first drain pipe and a second drain pipe. Inner threaded ends and outer threaded ends are respectively opened at both ends of the first drain pipe. Inner threaded ends and outer threaded ends are respectively opened at both ends of the second drain pipe. The inner threaded end of the first drain pipe is threadedly connected to the outer threaded end of the second drain pipe.

[0007] Preferably, the surfaces of the first drain pipe and the second drain pipe are both wrapped with geotextile filter layer cylinders, and drain holes are evenly opened on the first drain pipe and the second drain pipe.

[0008] Preferably, a plurality of threaded holes one are arranged in a circular array on the first drain pipe and the second drain pipe, and a plurality of threaded holes two are arranged in a circular array on the geotextile filter layer cylinder.

[0009] Preferably, the positioning bolt is threadedly connected to the third threaded hole, and extends from the second threaded hole to the first threaded hole.

[0010] The utility model has the following beneficial effects:

[0011] In the utility model, during the installation of the first drain pipe and the second drain pipe, workers have to wrap the strip-shaped filter layer geotextile tube around the first drain pipe and the second drain pipe one by one, which is laborious and troublesome; by respectively arranging the internal thread end and the external thread end at both ends of the first drain pipe and the second drain pipe, it is avoided that there is no connection structure at both ends of the first drain pipe and the second drain pipe, and only by inserting one end of the first drain pipe into one end of the second drain pipe, it is easy to cause disconnection of the first drain pipe and the second drain pipe and gaps at the connection, which affects the drainage work.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Refer to Figures 1-4 , a slope drain pipe, including a pressing strip 4, the pressing strip 4 is pressed against the circumferential outer wall of the filter layer geotextile tube 3, the inner diameter of the filter layer geotextile tube 3 is processed to be 1 mm larger than the outer diameter of the first drain pipe 1 and the second drain pipe 2, so that it is convenient for manual wrapping on the first drain pipe 1 and the second drain pipe 2, a third threaded hole 40 is opened on the pressing strip 4, and the third threaded hole 40 is threadedly connected with a positioning bolt 5.

[0019] Further, it further includes a first drain pipe 1 and a second drain pipe 2. Inner threaded ends 10 and outer threaded ends 20 are respectively provided at both ends of the first drain pipe 1. Inner threaded ends 10 and outer threaded ends 20 are respectively provided at both ends of the second drain pipe 2. The inner threaded end 10 of the first drain pipe 1 is threadedly connected to the outer threaded end 20 of the second drain pipe 2.

[0020] Further, the surfaces of the first drain pipe 1 and the second drain pipe 2 are both wrapped with an anti-filter layer geotextile tube 3. Drainage holes 21 are equidistantly provided on the first drain pipe 1 and the second drain pipe 2.

[0021] Further, a plurality of first threaded holes 22 are provided on the first drain pipe 1 and the second drain pipe 2 in an annular array. A plurality of second threaded holes 30 are provided on the anti-filter layer geotextile tube 3 in an annular array.

[0022] Further, the positioning bolt 5 is threadedly connected to the third threaded hole 40, the second threaded hole 30 into the first threaded hole 22.

[0023] The usage method and advantages of the present utility model: When the DC motor that is convenient for installation and fixation is in use, the working process is as follows:

[0024] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4 As shown, when using the device, the anti-filter layer geotextile tube 3 is sleeved on the surfaces of the first drain pipe 1 and the second drain pipe 2, and then the holes of the third threaded hole 40, the first threaded hole 22 and the second threaded hole 30 are aligned, or the positioning bolt 5 can be first threadedly screwed into the third threaded hole 40 and the second threaded hole 30 and then screwed into the first threaded hole 22;

[0025] Through the positioning of the pressing strip 4 and the positioning bolt 5, the anti-filter layer geotextile tube 3 can be tightly attached to the circumferential outer wall surfaces of the first drain pipe 1 and the second drain pipe 2, that is, the movement of the anti-filter layer geotextile tube 3 is avoided, and the labor and trouble of the worker wrapping the strip-shaped anti-filter layer geotextile tube 3 around the first drain pipe 1 and the second drain pipe 2 one by one during the installation of the first drain pipe 1 and the second drain pipe 2 are avoided.

[0026] When the first drain pipe 1 or the second drain pipe 2 is pre-buried in the slope, since the length of a single first drain pipe 1 or the second drain pipe 2 is short, the first drain pipe 1 and the second drain pipe 2 need to be connected. At this time, only the inner threaded end 10 and the outer threaded end 20 need to be aligned and screwed in, so that the first drain pipe 1 and the second drain pipe 2 are connected into a section for use, that is, the situation that the two ends of the first drain pipe 1 and the second drain pipe 2 are not provided with a connection structure is avoided. Only by inserting one end of the first drain pipe 1 into one end of the second drain pipe 2, it is easy to cause the disconnection of the first drain pipe 1 and the second drain pipe 2 and the gap at the connection affecting the drainage work is avoided.

[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
