[0019] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] Please refer to the attached Figure 1-2A cable trench for direct burial installation, comprising a plurality of U-shaped frames 1 fixed in the cable trench, wherein the plurality of U-shaped frames 1 are in contact with each other, and grooves are provided at two vertical portions at one end of the U-shaped frame 1, into which a rectangular plate 3 is inserted, and a plurality of circular grooves are provided in the groove, into which a round rod 7 is inserted, and the round rod 7 is connected and fixed to a surface of the rectangular plate 3 facing the circular groove, and a plurality of rectangular grooves communicating with the circular grooves are provided on two opposite side surfaces of the U-shaped frame 1, and a support plate 5 for laying cables is inserted in the rectangular groove, and a circular hole is provided at the contact point between the support plate 5 and the circular groove, and the round rod 7 is inserted in the circular hole.

[0022] The support plate 5 for laying cables is fixed by plugging the round rods 7, thereby saving the use of fixing workpieces such as bolts, reducing the installation cost and improving the efficiency. The U-shaped frame 1 is arranged in a mutually contacting manner, so that the multiple round rods 7 connected and fixed to the rectangular plate 3 continue to be supported and limited, and the single U-shaped frame 1 is easy to disassemble, thereby making maintenance and inspection more convenient.

[0023] In order to facilitate the insertion of the round rod 7 into the round hole, a horn groove 8 is provided on the side of the round hole facing the rectangular plate 3 .

[0024] In order to prevent the cables from sliding on the support plate 5 , a plurality of semicircular grooves 6 for fixing the cables are provided on the upper surface of the support plate 5 .

[0025] In order to protect the cables in the U-shaped frame 1 , a sealing plate 4 is connected and fixed to the upper surface of the U-shaped frame 1 .

[0026] In order to prevent rainwater from accumulating in the U-shaped frame 1 , a plurality of drainage grooves 2 are provided at the bottom of the U-shaped frame 1 .

[0027] The specific operation process of the utility model is as follows: first, multiple support plates 5 are inserted into the rectangular groove from the side close to the groove in sequence, and the round rods 7 are inserted into the round holes for fixing, until all the rectangular holes on the U-shaped frame 1 are inserted with the support plates 5, and then the next U-shaped frame 1 is installed, saving the use of bolts and other fixing workpieces, so that the installation cost and efficiency are improved.

[0028] The U-shaped frame 1 is used to support the rectangular plate 3 in the last installed U-shaped frame 1 to prevent the support plate 5 from shaking when laying the cable, causing the round rod 7 inserted in the support plate 5 to gradually separate from the groove.
