Utility model content
The purpose of this utility model is to provide a kind of and replaceablely faces upward oblique drainage hole structure.
According to one side of the present utility model, provide and a kind of replaceablely face upward oblique drainage hole structure, this is replaceable faces upward oblique drainage hole structure, comprise: the outer pvc pipe of hollow and the internal layer pvc pipe be sheathed in outer pvc pipe, described outer pvc pipe is provided with boring equably, be enclosed with the first screen cloth at the external surface of described outer pvc pipe, be enclosed with the second screen cloth at the external surface of described internal layer pvc pipe.
Further, the angle of the tube wall of described boring and described outer pvc pipe is 5 ° ~ 10 °, and the aperture of described boring is 100 ~ 150 millimeters.
Further, be a unit with the outer pvc pipe surface area of 100 square millimeters, in each unit, be provided with many five of the quantity of boring.
Further, the sieve mesh of described first screen cloth and the second screen cloth is 10 ~ 200.
Further, the aperture of described outer pvc pipe is 100 ~ 150 millimeters, and its optimum aperture is 100 millimeters.
Further, the aperture of described internal layer pvc pipe is 50 ~ 70 millimeters, and its optimum aperture is 50 millimeters.
The beneficial effects of the utility model are: for current side slope, it is little that the deep layer that the works tradition such as roadbed and tunnel uses faces upward oblique drain hole diameter, easy blocking, not easily change and affect defect or the deficiency such as its durability and draining effect, hereby have developed Novel replaceable and face upward oblique drainage hole structure, outer pvc pipe of the present utility model and the operation simultaneously of internal layer pvc pipe, and outsourcing is suitable for the filter material in aperture, have during silting and extract interior pipe, cleaning, replaceable, improve the advantages such as durability, therefore be suitable for very much in side slope, apply in the structure deep layer draining such as roadbed and tunnel.Through slope, the pearl north, the support engineering capital on-site verification of a year, it is respond well that on-the-spot deep layer faces upward oblique water drainage, do not occur the diseases such as silting, and interior pipe can extract cleaning, considerably increases the durability of drain hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and Fig. 2 show schematically show and face upward oblique drainage hole structure according to one of the present utility model is replaceable.
The one that the present embodiment provides is replaceable faces upward oblique drainage hole structure, as shown in Figure 1, comprise: the outer pvc pipe 10 of hollow and the internal layer pvc pipe 20 be sheathed in outer pvc pipe 10, wherein, the aperture of described outer pvc pipe 10 is 100 ~ 150 millimeters, and the aperture of internal layer pvc pipe 20 is 50 ~ 70 millimeters; Be enclosed with the first screen cloth 30 at the external surface of described outer pvc pipe 10, be enclosed with the second screen cloth 40 at the external surface of described internal layer pvc pipe 20, the sieve mesh of described first screen cloth 30 and the second screen cloth 40 is 10 ~ 200; Specifically on described outer pvc pipe 10, be provided with boring 11 equably, be a unit with outer pvc pipe 10 surface area of 100 square millimeters, many five of the quantity of boring 11 is provided with in each unit, boring 11 is 5 ° ~ 10 ° with the angle of the tube wall of described outer pvc pipe 10 in addition, and the aperture of described boring 11 is 100 ~ 150 millimeters.
Above-mentioned each aperture, sieve mesh, angle etc. can adjust according to actual conditions:
As in embodiment 1, the aperture of outer pvc pipe 10 is 100 millimeters, and the aperture of internal layer pvc pipe 20 is 50 millimeters, first screen cloth 30 is 10, the sieve mesh of the second screen cloth 40 is 140, and boring 11 is 5 ° with the angle of the tube wall of described outer pvc pipe 10, and the aperture of boring 11 is 100 millimeters;
And for example in embodiment 2, the aperture of outer pvc pipe 10 is 150 millimeters, and the aperture of internal layer pvc pipe 20 is 70 millimeters, first screen cloth 30 is 100, the sieve mesh of the second screen cloth 40 is 200, and boring 11 is 10 ° with the angle of the tube wall of described outer pvc pipe 10, and the aperture of boring 11 is 150 millimeters;
