[0005] A drainage ditch, the upper end of one side wall has a positioning groove;

[0006] A retaining net, a circle of frames is fixedly sleeved on the outer side wall, and one side of the frame is detachably fixedly connected to the positioning groove;

[0007] A plurality of support components are arranged on the frame, and the support components are located on the frame of the retaining net on the side opposite to the positioning groove;

[0008] The support component includes

[0009] A support column, located below the frame;

[0010] A threaded column is arranged on the support column;

[0011] Wherein, the frame has a second positioning hole corresponding to the position of the threaded column, and the threaded column penetrates

[0012] through the second positioning hole and is fixedly connected to a nut.

[0013] Preferably, a gasket is sleeved on the threaded column, and the aperture of the gasket is smaller than the diameter of the support column.

[0014] Preferably, the frame has a plurality of first positioning holes corresponding to the position of the positioning groove, the inner wall of the positioning groove has a threaded groove corresponding to the position of the first positioning hole, and a screw rod penetrating through the first positioning hole and threadedly connected to the threaded groove is arranged in the first positioning hole.

[0015] Preferably, a T-shaped sliding groove is provided on the side frame of the retaining net opposite to the positioning groove, and a baffle is slidably arranged in the sliding groove, and the baffle is inclined.

[0016] The beneficial effects of adopting the above technical solutions are as follows:

[0017] In this application, the support columns provided on the frame can support one end of the frame far from the positioning groove, so that the entire retaining net can be stable. At the same time, in this application, support columns of different lengths can adapt to drainage ditches of different depths, making the use more flexible. At the same time, the baffle can block the protruding threaded posts to prevent scratching workers or tires. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0025] As Figures 1-5 , in the first embodiment, a retaining net for an underground drainage ditch includes

[0026] a drainage ditch 20, and a positioning groove 43 is provided at the upper end of one side wall;

[0027] a retaining net 30, and a frame 40 is fixedly sleeved on the outer side wall, and one side of the frame 40 is detachably and fixedly connected to the positioning groove 43;

[0028] a plurality of support assemblies 60 are arranged on the frame 40, and the support assemblies 60 are located on the frame 40 of the retaining net 30 opposite to the positioning groove 43;

[0029] The support assembly 60 includes

[0030] a support column 61 located below the frame 40;

[0031] a threaded column 62 disposed on the support column 61;

[0032] Wherein, the frame 40 has a second positioning hole 42 corresponding to the threaded column 62, and the threaded column 62 passes through the second positioning hole 42 and is fixedly connected to a nut 63.

[0033] This embodiment is implemented as follows:

[0034] When this application is in use, by connecting the nut 63 to the threaded column 62, the support column 62 can be fixed on the frame 20. At this time, the support column 61 can extend into the drainage ditch 20 to support one side of the frame 20. And when this application is in use, workers can replace the support columns 61 with different lengths according to the depth of the drainage ditch 20.

[0035] Please refer to Figure 2 , a gasket 64 is sleeved on the threaded column 62, and the aperture of the gasket 64 is smaller than the diameter of the support column 61;

[0036] Selecting an appropriate number of gaskets 64 can adjust the height of the frame 20.
