Description

Technical Field

[0001] The invention belongs to the technical field of electric power facilities, in particular to an assembled power cable trench prefabricated component. Background Art

[0002] The cable trench is an underground pipeline used for laying and replacing power or telecommunication cable facilities. It is also the enclosure structure for the laid cable facilities. There are rectangular, circular, arched and other pipeline structural forms. Cable supports are installed in the cable trench. The cable supports are usually made of metal materials and are fixed to the trench wall by welding or screws. The cables are supported by the supports and maintain a certain distance from the bottom of the trench.

[0003] The cable trench is generally made of concrete or brick, and the top is covered with a cover plate. The cover plate surface can be flush with the ground for easy opening, or slightly lower than the ground and a layer of cement is painted on the cover plate to prevent the unevenness of the cover plate and the ground and rainwater from entering the cable trench; depending on the number of cables laid, the cables can be placed in a single layer at the bottom of the cable trench, or in layers on the brackets of the cable trench, and most of them use the latter form; the cables laid in layers have longitudinal and transverse spacing; the cable brackets can be installed on one side or both sides of the cable trench according to the number of cables laid; a certain width of channel is left between the brackets on both sides or between the brackets and the side wall of the cable trench (single-side brackets).

[0004] During the use of power cable trenches, a cable mounting frame for support is usually installed inside the cable trench. During the subsequent cable laying process, the cables are laid in layers on the cable mounting frame. Existing cable support frames are generally made of metal. During installation, the mounting frame is mainly fixed to the side wall of the cable trench by expansion bolts. However, this form often increases the workload during the laying of the cables, resulting in low installation efficiency of the mounting frame inside the cable trench. At the same time, when disassembly is required, it is often difficult to achieve rapid disassembly. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes an assembled power cable trench prefabricated component. The present invention is mainly used to solve the problem of the inconvenience of the existing cable trench bracket during installation and disassembly.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an assembled power cable trench prefabricated component, including a trench body, a cover plate, a mounting groove and a support frame; the cover plate is arranged on the upper part of the trench body; the cover plate is overlapped with the trench body; the mounting grooves are evenly spaced on the side walls of the trench body; limiting parts are arranged on the upper and lower sides of one end of the mounting groove; the limiting part is fixedly connected to the trench body; the support frame is arranged inside the mounting groove; the support frame is slidably connected to the inner wall of the mounting groove; the limiting part is used to limit the support frame from rotating in the vertical direction inside the mounting groove.

[0007] During operation, an installation groove is opened on the side wall of the trench body (the length of the installation groove is longer than twice the width of the support frame, and the height of one side of the installation groove is greater than the height of the support frame). During installation, the construction personnel can easily place one side of the support frame into the interior of the installation groove, and then push it horizontally to move the support frame toward one side of the installation groove. Since limited position portions are arranged on the upper and lower sides of one end of the installation groove, the installation frame can no longer move except for sliding in the horizontal direction, so as to meet the function of supporting the cable, and the support frame can be quickly installed, thereby improving the efficiency of the cable trench during cable laying. At the same time, since no additional drilling and locking bolts are required during the installation and disassembly process, the installation and disassembly work is reduced, making the cable trench convenient in use. At the same time, when adding or reducing support frames, it can be more convenient and easy to operate, thereby improving the applicability of the cable trench.

[0008] Preferably, a sliding bar is provided on the side wall of the mounting groove; the sliding bar is fixedly connected to the side wall of the mounting groove; the sliding bar is slidably connected to the side wall of the support frame; wherein a sliding rod is provided on the limiting portion at the lower part of the mounting groove; the sliding rod is connected to the limiting portion; and the support frame is in contact with the sliding rod.

[0009] During operation, since the surface of the concrete is relatively rough and the weight of the support frame is large, the resistance to the movement of the support frame is large during the sliding process, which makes the installation of the support frame more difficult; therefore, in the present solution, a sliding bar is provided on the side wall of the installation groove, so that the contact area between the support frame and the side wall of the installation groove can be maintained, thereby reducing the resistance when the support frame slides, and at the same time, since the surface of the sliding bar is relatively smoother than the concrete surface, the friction resistance of the sliding bar is small, further reducing the resistance when the support frame moves; at the same time, during the sliding process of the support frame, the gravity of the support frame mainly acts on the bottom surface of the installation groove, thereby causing the friction resistance of the bottom surface to be large during the sliding process, therefore, in the present solution, a sliding rod is provided on the limiting portion, and the sliding rod contacts the support frame during installation, so that the bottom surface of the support frame does not contact the bottom of the installation groove, thereby avoiding friction on the ground, and at the same time, since the surface of the sliding rod is relatively smooth and the contact surface is small, the resistance to the support rod during the movement is reduced, further improving the convenience of the installation of the support frame.

[0010] Preferably, springs are evenly spaced apart at the lower portion of the sliding rod; one end of the spring is fixedly connected to the sliding rod; and the other end of the spring is fixedly connected to the limiting portion.

[0011] During operation, due to the small contact area between the sliding rod and the support frame, the stability of the support frame after installation is reduced. Therefore, in the present solution, a spring is arranged at the lower part of the sliding rod, and during installation, the spring props up the sliding rod, so that the support frame does not contact the bottom surface of the installation groove, so that the support frame can be installed more easily. After the support frame is installed, after the cable is placed on the support frame, the spring is compressed under the action of the gravity of the cable, so that the bottom surface of the support frame contacts the side wall of the installation groove, so that the support frame is more stable during use after installation. At the same time, due to the arrangement of the spring, when the cable trench is in use and is subjected to external vibration interference, the spring can absorb part of the vibration impact through its own deformation, so that the cable is less impacted, thereby protecting the cable.

[0012] Preferably, a sawtooth structure is provided on the bottom surface of the support frame; and a clamping structure cooperating with the sawtooth structure is provided at one end of the mounting groove close to the limiting portion.

[0013] During operation, after the support frame is installed, the support frame can still move in the horizontal direction, which reduces the stability of the support frame. At the same time, since the cable is sometimes laid in the form of dragging during the laying process, there is a risk of causing the support frame to fall off. Therefore, in the present solution, a serrated structure is provided on the bottom surface of the support frame, and a clamping structure is provided on the bottom surface of the installation groove. After the support frame is installed in place and the cable is overlapped on the support frame, the support frame moves downward under the center and bottom of the cable gravity, so that the serrated structure cooperates with the clamping structure on the installation groove, so that the movement of the support frame in the horizontal direction is restricted, thereby improving the stability of the support frame after installation, thereby avoiding the situation where the support frame slides due to the dragging of the cable during the laying process, thereby improving the safety of the cable installation.

[0014] Preferably, spiral sleeves are symmetrically arranged on both sides of the mounting groove; the spiral sleeves are fixedly connected to the groove body; a screw is arranged inside the spiral sleeve; the screw is threadedly connected to the spiral sleeve; a cam is arranged at one end of the screw; the cam is fixedly connected to the screw; a handwheel is arranged on one side of the cam; the handwheel is fixedly connected to the screw.

[0015] During operation, since the cables in the cable trench usually need to be repaired or the lines need to be modified and upgraded, there will be an increase or decrease in the number of support frames. At the same time, since the part of the support frame that receives the cables is usually inclined, the cables often need to be moved diagonally upward when they are detached from the support frame. Therefore, in this solution, screw rods are arranged on both sides of the support frame, and then when the cables need to be lifted, the screw rods are rotated by a handwheel, so that the screw rods move in the horizontal direction. At the same time, since a cam is arranged on the screw rod, the cam rotates as the screw rod moves, so that the cables move in the vertical direction, so that the cables move diagonally upward, so that the cables are detached from the support frame, and the support frame can move in the horizontal direction, which facilitates the removal and replacement of the support frame, thereby improving the convenience of maintenance and replacement of the cable trench, and thereby improving the practicality of the cable trench.

[0016] Preferably, an elastic extrusion bag is provided on the upper part of the support frame; one side of the elastic extrusion bag is fixedly connected to the support frame; clamping claws are symmetrically provided on both sides of the elastic extrusion bag; the clamping claws are slidably connected to the elastic extrusion bag; a flap is provided at one end of one of the clamping claws; one end of the flap is rotatably connected to the clamping claw; a protrusion is provided at one end of the other clamping claw; a clamping portion is provided at the other end of the flap; and the clamping portion cooperates with the protrusion.

[0017] During operation, when the cable is placed on the support frame, the cable's own gravity causes the cable to squeeze the elastic extrusion bag, thereby reducing the volume of the elastic extrusion bag, thereby increasing the pressure inside the elastic extrusion bag, causing the clamping claw to extend outward to wrap the cable, and then the flap is rotated to engage the clamping part and the protrusion, so that the clamping claw clamps the cable column, thereby preventing the cable from falling off, thereby improving the stability of the cable, and thereby improving the safety of the cable trench.

[0018] Preferably, slideways are symmetrically arranged on both sides of the outside of the ditch body; a water-blocking bin is arranged inside the slideway; the water-blocking bin is slidably connected to the slideway; and a filtering hole is arranged on the side of the water-blocking bin away from the ditch body.

[0019] During operation, by setting a water-blocking bin on the side of the trench body, when rainwater from the outside enters the cable trench, it will first gather inside the water-blocking bin, thereby avoiding the formation of a mud layer between the trench body and the soil, thereby avoiding the deviation of the trench body during later use, thereby improving the stability of the cable trench. At the same time, since water gathers inside the water-blocking bin, due to its large specific heat capacity, it can absorb more heat, which can have a better cooling effect on the trench body, thereby reducing the temperature of the internal cable and improving the safety of the trench body.

[0020] Preferably, main reinforcement is arranged inside the groove body; the main reinforcement is arranged in the middle of the side wall of the groove body; auxiliary reinforcement is arranged at the limiting part; and the auxiliary reinforcement is fixedly connected to the main reinforcement.

[0021] During operation, in this solution, during use of the support frame, under the action of the gravity of the cable, the force points of the trench body are mainly distributed at the limiting portion. Therefore, stress concentration is often easy to occur at the limiting portion, which can easily cause damage there. Therefore, in this solution, main reinforcement is arranged along the vertical direction of the red wall of the trench body, and then auxiliary reinforcement is arranged at the limiting portion, and the auxiliary reinforcement is fixedly connected to the main reinforcement, thereby improving the structural strength of the limiting portion, and at the same time improving the shaping direction of the trench body, thereby improving the strength of the trench body, and thereby improving the service life of the trench body.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, an installation groove is opened on the side wall of the trench body (the length of the installation groove is longer than twice the width of the support frame, and the height of one side of the installation groove is greater than the height of the support frame). Therefore, during installation, the construction personnel can easily place one side of the support frame into the interior of the installation groove, and then push it horizontally, so that the support frame moves toward one side of the installation groove. Since limited positions are provided on the upper and lower sides of one end of the installation groove, the installation frame can no longer move except for sliding in the horizontal direction, so that the function of supporting the cable can be met, and the support frame can be quickly installed, thereby improving the efficiency of the cable trench during cable laying. At the same time, since no additional drilling and locking bolts are required during the installation and disassembly process, the installation and disassembly work is reduced, thereby making the cable trench convenient in use. At the same time, when adding or reducing the support frame, it can be more convenient and easy to operate, thereby improving the applicability of the cable trench.

[0024] 2. In the present invention, since the surface of the concrete is relatively rough and the weight of the support frame is large, the resistance to the movement of the support frame is large during the sliding process, which makes the installation of the support frame more difficult; therefore, in this solution, by arranging a sliding bar on the side wall of the installation groove, the contact area between the support frame and the side wall of the installation groove can be maintained, thereby reducing the resistance of the support frame when sliding, and at the same time, since the surface of the sliding bar is relatively smoother than the concrete surface, the friction resistance of the sliding bar is small, further reducing the resistance of the support frame when moving; at the same time, during the sliding process of the support frame, the gravity of the support frame mainly acts on the bottom surface of the installation groove, thereby causing the friction resistance of the bottom surface to be large during the sliding process, therefore, in this solution, by arranging a sliding rod on the limiting part, the sliding rod contacts the support frame during installation, so that the bottom surface of the support frame does not contact the bottom of the installation groove, thereby avoiding friction on the ground, and at the same time, since the surface of the sliding rod is relatively smooth and the contact surface is small, the resistance to the support rod during the movement is reduced, further improving the convenience of installation of the support frame.

[0025] 3. In the present invention, since the contact area between the sliding rod and the support frame is small, the stability of the support frame after installation is reduced. Therefore, in this scheme, a spring is arranged at the lower part of the sliding rod, and during installation, the spring props up the sliding rod, so that the support frame does not contact the bottom surface of the installation groove, so that the support frame can be installed more easily. After the support frame is installed, after the cable is placed on the support frame, the spring is compressed under the action of the gravity of the cable, so that the bottom surface of the support frame contacts the side wall of the installation groove, so that the support frame is more stable during use after installation; at the same time, since the spring is arranged, when the cable trench is in use and is subjected to external vibration interference, the spring can absorb part of the vibration impact through its own deformation, so that the cable is less impacted, thereby protecting the cable.

[0026] 4. In the present invention, after the support frame is installed, the support frame can still move in the horizontal direction, which reduces the stability of the support frame. At the same time, since the cable is sometimes laid in the form of dragging during the laying process, there is a risk of causing the support frame to fall off. Therefore, in this solution, a serrated structure is provided on the bottom surface of the support frame, and a clamping structure is provided on the bottom surface of the installation groove. After the support frame is installed in place and the cable is overlapped on the support frame, the support frame moves downward under the center and bottom of the cable gravity, and the serrated structure cooperates with the clamping structure on the installation groove, so that the movement of the support frame in the horizontal direction is restricted, thereby improving the stability of the support frame after installation, thereby avoiding the situation where the support frame slides due to the dragging of the cable during the laying process, and thereby improving the safety of the cable installation.

[0027] 5. In the present invention, since the cables in the cable trench usually need to be repaired or the lines need to be modified and upgraded, there will be an increase or decrease in the number of support frames. At the same time, since the part of the support frame that receives the cables is usually arranged at an angle, the cables often need to be moved diagonally upward when they are separated from the support frame. Therefore, in the present solution, screw rods are arranged on both sides of the support frame, and when the cables need to be lifted, the screw rods are rotated by a hand wheel, so that the screw rods move in the horizontal direction. At the same time, since a cam is arranged on the screw rod, the cam rotates as the screw rod moves, so that the cables move in the vertical direction, so that the cables move diagonally upward, so that the cables are separated from the support frame, and the support frame can move in the horizontal direction, which facilitates the removal and replacement of the support frame, thereby improving the convenience of maintenance and replacement of the cable trench, and thereby improving the practicality of the cable trench.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 8 As shown, an assembled power cable trench prefabricated component is characterized in that: it includes a trench body 1, a cover plate 2, a mounting groove 3 and a support frame 4; the cover plate 2 is arranged on the upper part of the trench body 1; the cover plate 2 is overlapped with the trench body 1; the mounting grooves 3 are evenly spaced on the side walls of the trench body 1; limiting parts 5 are arranged on the upper and lower sides of one end of the mounting groove 3; the limiting part 5 is fixedly connected to the trench body 1; the support frame 4 is arranged inside the mounting groove 3; the support frame 4 is slidably connected to the inner wall of the mounting groove 3; the limiting part 5 is used to limit the support frame 4 from rotating in the vertical direction inside the mounting groove 3.

[0040] During operation, in the process of using the power cable trench, a cable mounting frame for support is usually installed inside the cable trench. In the subsequent cable laying process, the cables are laid in layers on the cable mounting frame. The existing cable support frame 4 is generally made of metal. During installation, the mounting frame is mainly fixed to the side wall of the cable trench by expansion bolts. However, since this form often increases the workload during the laying of the cables, the installation efficiency of the mounting frame inside the cable trench is low. At the same time, when disassembly is required, it is often difficult to achieve rapid disassembly. Therefore, in this solution, a mounting groove 3 is opened on the side wall of the trench body 1 (the length of the mounting groove 3 is twice the width of the supporting frame 4, and the height of one side of the mounting groove 3 is greater than the height of the supporting frame 4). During installation, the construction personnel One side of the support frame 4 can be easily placed into the interior of the installation groove 3, and then pushed horizontally to make the support frame 4 move toward one side of the installation groove 3. Since the limiting parts 5 are arranged on the upper and lower sides of one end of the installation groove 3, the installation frame can slide in the horizontal direction but can no longer move, so as to meet the function of supporting the cable, and the support frame 4 can be quickly installed, thereby improving the efficiency of the cable trench during cable laying. At the same time, during the installation and disassembly process, no additional drilling and locking bolts are required, thereby reducing the installation and disassembly work, thereby making the cable trench convenient in use. At the same time, when adding or reducing the support frame 4, it can be more convenient and easy to operate, thereby improving the applicability of the cable trench.

[0041] like Figure 3 and Figure 5 As shown, a sliding bar 6 is provided on the side wall of the mounting groove 3; the sliding bar 6 is fixedly connected to the side wall of the mounting groove 3; the sliding bar 6 is slidably connected to the side wall of the support frame 4; wherein a sliding rod 7 is provided on the limiting portion 5 at the lower part of the mounting groove 3; the sliding rod 7 is connected to the limiting portion 5; and the support frame 4 is in contact with the sliding rod 7.

[0042] During operation, since the surface of the concrete is relatively rough and the weight of the support frame 4 is relatively large, the resistance to the movement of the support frame 4 is relatively large during the sliding process, which makes the installation of the support frame 4 difficult; therefore, in this solution, by providing a slide bar 6 on the side wall of the installation groove 3, the contact area between the support frame 4 and the side wall of the installation groove 3 can be maintained, thereby reducing the resistance of the support frame 4 when sliding. At the same time, since the surface of the slide bar 6 is relatively smoother than the concrete surface, the friction resistance of the slide bar 6 is relatively small, further reducing the resistance of the support frame 4 when moving; At the same time, during the sliding of the support frame 4, the gravity of the support frame 4 mainly acts on the bottom surface of the installation groove 3, which makes the friction resistance of the bottom surface during the sliding process larger. Therefore, in the present solution, a sliding rod 7 is arranged on the limiting portion 5, and the sliding rod 7 contacts the support frame 4 during installation, so that the bottom surface of the support frame 4 does not contact the bottom of the installation groove 3, thereby avoiding friction on the ground. At the same time, since the surface of the sliding rod 7 is relatively smooth and the contact area is small, the resistance encountered by the support rod during the movement is reduced, further improving the convenience of installation of the support frame 4.

[0043] like Figure 2 , Figure 3 and Figure 8 As shown, springs 8 are evenly spaced apart at the lower portion of the sliding rod 7 ; one end of the spring 8 is fixedly connected to the sliding rod 7 ; and the other end of the spring 8 is fixedly connected to the limiting portion 5 .

[0044] During operation, since the contact area between the sliding rod 7 and the support frame 4 is small, the stability of the support frame 4 after installation is reduced. Therefore, in the present solution, a spring 8 is arranged at the lower part of the sliding rod 7, and during installation, the spring 8 props up the sliding rod 7, so that the support frame 4 does not contact the bottom surface of the installation groove 3, so that the support frame 4 can be installed more easily. After the support frame 4 is installed, after the cable is placed on the support frame 4, the spring 8 is compressed under the action of the gravity of the cable, so that the bottom surface of the support frame 4 contacts the side wall of the installation groove 3, so that the support frame 4 is more stable during use after installation; at the same time, since the spring 8 is arranged, when the cable trench is in use and is subjected to external vibration interference, the spring 8 can absorb part of the vibration impact through its own deformation, so that the cable is subjected to less impact, thereby protecting the cable.

[0045] like Figure 4 and Figure 5 As shown, a sawtooth structure 9 is disposed on the bottom surface of the support frame 4 ; and a clamping structure 10 cooperating with the sawtooth structure 9 is disposed at one end of the mounting groove 3 close to the limiting portion 5 .

[0046] During operation, after the support frame 4 is installed, the support frame 4 can still move in the horizontal direction, which reduces the stability of the support frame 4. At the same time, since the cable is sometimes laid in the form of dragging during the laying process, there is a risk of causing the support frame 4 to fall off; therefore, in this solution, a serrated structure 9 is provided on the bottom surface of the support frame 4, and a clamping structure 10 is provided on the bottom surface of the installation groove 3. After the support frame 4 is installed in place and the cable is overlapped on the support frame 4, the support frame 4 moves downward under the center and bottom of the cable gravity, so that the serrated structure 9 cooperates with the clamping structure 10 on the installation groove 3, so that the movement of the support frame 4 in the horizontal direction is restricted, thereby improving the stability of the support frame 4 after installation, thereby avoiding the situation where the support frame 4 slides due to the dragging of the cable during the laying process, thereby improving the safety of the cable installation.

[0047] like Figure 2 and Figure 6 As shown, spiral sleeves 11 are symmetrically arranged on both sides of the mounting groove 3; the spiral sleeves 11 are fixedly connected to the groove body 1; a screw rod 12 is arranged inside the spiral sleeve 11; the screw rod 12 is threadedly connected to the spiral sleeve 11; a cam 13 is arranged at one end of the screw rod 12; the cam 13 is fixedly connected to the screw rod 12; a hand wheel 14 is arranged on one side of the cam 13; the hand wheel 14 is fixedly connected to the screw rod 12.

[0048] During operation, since the cables in the cable trench usually need to be repaired or the lines need to be modified and upgraded, there will be situations where the support frame 4 is increased or decreased. At the same time, since the part of the support frame 4 that receives the cables is usually arranged at an angle, the cables often need to be moved diagonally upward when they are separated from the support frame 4. Therefore, in this solution, screw rods 12 are arranged on both sides of the support frame 4, and then when the cables need to be lifted, the screw rods 12 are rotated by the handwheel 14, so that the screw rods move in the horizontal direction. At the same time, since a cam 13 is arranged on the screw rod 12, as the screw rod 12 moves, the cam 13 rotates, so that the cables move in the vertical direction, so that the cables move diagonally upward, so that the cables are separated from the support frame 4, so that the support frame 4 can move in the horizontal direction, so that the removal and replacement of the support frame 4 is convenient, so that the convenience of maintenance and replacement of the cable trench is improved, and the practicality of the cable trench is improved.

[0049] like Figure 7As shown, an elastic extrusion bag 15 is provided on the upper part of the support frame 4; one side of the elastic extrusion bag 15 is fixedly connected to the support frame 4; clamping claws 16 are symmetrically provided on both sides of the elastic extrusion bag 15; the clamping claws 16 are slidably connected to the elastic extrusion bag 15; one end of one of the clamping claws 16 is provided with a flap 17; one end of the flap 17 is rotatably connected to the clamping claw 16; one end of the other clamping claw 16 is provided with a protrusion; the other end of the flap 17 is provided with a clamping portion 18; the clamping portion 18 cooperates with the protrusion.

[0050] During operation, when the cable is placed on the support frame 4, the cable's own gravity causes the cable to squeeze the elastic squeezing bag 15, thereby reducing the volume of the elastic squeezing bag 15, thereby increasing the pressure inside the elastic squeezing bag 15, and causing the clamping claw 16 to extend outward to wrap the cable, and then the flap 17 is rotated to engage the clamping portion 18 and the protrusion, so that the clamping claw 16 clamps the cable column, thereby preventing the cable from falling off, thereby improving the stability of the cable, and thereby improving the safety of the cable trench.

[0051] like Figure 1 and Figure 2 As shown, slideways 19 are symmetrically arranged on both sides of the outside of the ditch body 1; a water-blocking bin 20 is arranged inside the slideway 19; the water-blocking bin 20 is slidably connected to the slideway 19; and a filtering hole is arranged on the side of the water-blocking bin 20 away from the ditch body 1.

[0052] During operation, by setting a water-blocking bin 20 on the side of the ditch body 1, when external rainwater enters the range of the cable trench, it will be preferentially collected in the water-blocking bin 20, thereby avoiding the formation of a mud layer between the ditch body 1 and the soil, thereby avoiding the ditch body 1 from being tilted during later use, thereby improving the stability of the cable trench, and at the same time, because water is collected in the water-blocking bin 20, due to the large specific heat capacity of water, it can absorb more heat, thereby having a better cooling effect on the ditch body 1, thereby reducing the temperature of the internal cable, thereby improving the safety of the ditch body 1.

[0053] like Figure 8 As shown, a main rib 21 is arranged inside the groove body 1 ; the main rib 21 is arranged in the middle of the side wall of the groove body 1 ; a secondary rib 22 is arranged at the limiting portion 5 ; the secondary rib 22 is fixedly connected to the main rib 21 .

[0054] During operation, in this solution, during use of the support frame 4, under the action of the gravity of the cable, the force points of the trench body 1 are mainly distributed at the limiting portion 5. Therefore, stress concentration is often easy to occur at the limiting portion 5, which can easily cause damage there. Therefore, in this solution, a main reinforcement 21 is arranged along the vertical direction of the red wall of the trench body 1, and then a secondary reinforcement 22 is arranged at the limiting portion 5, and the secondary reinforcement 22 is fixedly connected to the main reinforcement 21, thereby improving the structural strength of the limiting portion 5, and at the same time improving the shaping direction of the trench body 1, thereby improving the strength of the trench body 1, and thereby improving the service life of the trench body 1.

[0055] During operation, by opening an installation groove 3 on the side wall of the trench body 1 (the length of the installation groove 3 is twice the width of the support frame 4, and the height of one side of the installation groove 3 is greater than the height of the support frame 4), during installation, the construction personnel can easily place one side of the support frame 4 into the interior of the installation groove 3, and then push it horizontally, so that the support frame 4 moves toward one side of the installation groove 3. Since the limiting parts 5 are provided on the upper and lower sides of one end of the installation groove 3, the installation frame can no longer move except for sliding in the horizontal direction, so that it can meet the function of supporting the cable, and the support frame 4 can be quickly installed, thereby improving the efficiency of the cable trench during cable laying. At the same time, since no additional drilling and locking bolts are required during the installation and disassembly process, the installation and disassembly work is reduced, making the cable trench convenient during use. At the same time, when adding or reducing the support frame 4, it can be more convenient and easy to operate. The utility model discloses that the utility model discloses ...
