[0026] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] The following is combined with Figure 1 The present invention is described in further detail.

[0028] The embodiment of the present invention discloses a support device and construction method for a trench. Figure 1 The supporting device for the groove includes a supporting assembly 1, which includes a supporting rod 11 with adjustable length and a baffle 12 for contacting the groove walls on both sides of the groove. The baffle 12 is provided with two pieces, which are respectively hinged to the two ends of the supporting rod 11, and the hinge point is located at the center position of the baffle 12. The baffle 12 can be rotated on the supporting rod 11, and the inclination angle of the two baffles 12 can be adjusted according to the inclination angle of the groove walls on both sides of the groove, so that the baffle 12 is more closely fitted to the groove walls on both sides of the groove, and the two baffles 12 are respectively pressed against the groove walls on both sides of the groove by adjusting the length of the supporting rod 11.

[0029] The support assembly 1 also includes an adjusting screw 13. In this embodiment, two support rods 11 are provided, and two baffles 12 are respectively hinged on the two support rods 11. The ends of the two support rods 11 away from the baffles 12 are provided with external threads that match the internal threads of the adjusting screw 13, and the external threads on the two support rods 11 are in opposite directions. The two ends of the adjusting screw 13 can be sleeved on the two support rods 11 and matched with the support rod 11 threads. By rotating the adjusting screw 13, the two support rods 11 can be moved in opposite directions, and the length of the support rod 11 can be adjusted, so that the two baffles 12 can be more tightly pressed against the two side walls of the groove, which can effectively support the groove walls.

[0030] A reinforcement assembly 2 for reinforcing the baffle 12 is also provided on the two support rods 11. The reinforcement assembly 2 includes a reinforcement rod 21 with adjustable length and a sleeve 22 slidably mounted on the support rod 11. The two ends of the reinforcement rod 21 are hinged to the lower side wall of the sleeve 22 and the baffle 12 respectively. The hinge point of the reinforcement rod 21 and the baffle 12 is located below the hinge point of the support rod 11 and the baffle 12. By adjusting the length of the reinforcement rod 21, the sleeve 22 can be moved on the support rod 11, and at the same time, the position of the baffle 12 close to the lower side can be pressed against the groove walls on both sides of the groove, thereby reinforcing the baffle 12 and further increasing the support effect on the groove walls on both sides of the groove.

[0031] The reinforcement assembly 2 also includes an adjusting rod 23. There are two reinforcement rods 21. The two reinforcement rods 21 are hinged to the sleeve 22 and the baffle 12 respectively. The movable ends of the two reinforcement rods 21 are hollow and the hollow side walls of the two reinforcement rods 21 are provided with internal threads in opposite directions. The two ends of the adjusting rod 23 are provided with external threads in opposite directions. The two ends of the adjusting rod 23 are respectively inserted into the hollow positions of the two reinforcement rods 21 and are threadedly matched with the two reinforcement rods 21. By rotating the adjusting rod 23, the two reinforcement rods 21 can be moved in opposite directions, thereby reinforcing the baffle 12.

[0032] At the same time, in order to facilitate the rotation of the adjusting rod 23, the middle position of the adjusting rod 23 is set flat. When the adjusting rod 23 needs to be rotated, the adjusting rod 23 can be rotated using tools such as a wrench, making the rotation of the adjusting rod 23 more convenient.

[0033] During the construction process, increased vibration is likely to occur. During the vibration process, the adjusting screw 13 is likely to rotate, resulting in a change in the distance between the two support rods 11, which affects the support effect. A fastening assembly 3 is provided on each of the two support rods 11. The fastening assembly 3 includes a fastening tube 31. The fastening tube 31 is arranged between the sleeve 22 and the adjusting screw 13. In this embodiment, four fastening tubes 31 are provided and are slidably sleeved on the two support rods 11 in pairs. The two fastening tubes 31 on the same support rod 11 are respectively pressed against the ends of the adjusting screw 13 and the sleeve 22, locking the sleeve 22 and the adjusting screw 13 on the support rod 11 to prevent the sleeve 22 and the adjusting screw 13 from moving.

[0034] The fastening assembly 3 also includes a fixing rod 32, an adjusting tube 33, a push rod 34 and a locking sleeve 35. The fixing rod 32 vertically passes through the support rod 11 and is inserted at the bottom of the groove, and the fixing rod 32 is located in the middle position of the sleeve 22 and the adjusting screw 13. The adjusting tube 33 is slidably sleeved on the fixing rod 32 and is located above the support rod 11. The push rod 34 is symmetrically arranged on both sides of the adjusting tube 33 and the two ends are hinged to the adjusting tube 33 and the two fastening tubes 31 respectively. The locking sleeve 35 is threadedly sleeved on the fixing rod 32. The locking sleeve 35 is rotated downwards and pushes the adjusting tube 33 downwards. During the downward movement of the adjusting tube 33, the two push rods 34 are pushed back on both sides. The two push rods 34 can push the two fastening tubes 31 on the support rod 11 to move to both sides and press against the ends of the sleeve 22 and the adjusting screw 13, locking the sleeve 22 and the adjusting screw 13 on the support rod 11, which can further enhance the stability of the baffle 12 on the groove walls on both sides of the groove.

[0035] At the same time, in order to increase the overall strength of the device, fastening bolts 14 are threadedly installed on both support rods 11. By rotating the fastening bolts 14, the fastening bolts 14 can be tightened against the side wall of the fixing rod 32, fixing the fixing rod 32 on the support rod 11, so that the fixing rod 32 and the support rod 11 become one, which can enhance the overall strength of the device.

[0036] A trench support construction method comprising the following steps:

[0037] Step 1: Turn the adjusting screw 13 to adjust the length of the support rod 11 according to the groove width, so that the baffle 12 contacts the groove walls on both sides of the groove;

[0038] Step 2: Turn the adjusting rod 23 to adjust the length of the reinforcing rod 21 and press the baffle 12 against the groove walls on both sides of the groove;

[0039] Step 3: Insert the fixing rod 32 through the support rod 11 into the bottom of the groove, and use the fastening bolts 14 on the support rod 11 to fix the fixing rod 32;

[0040] Step 4: Rotate the locking sleeve 35 downward so that the locking sleeve 35 pushes the adjusting tube 33 downward. During the downward movement of the adjusting tube 33, the push rod 34 pushes the fastening tube 31 to move to both sides and abuts against the ends of the adjusting screw tube 13 and the sleeve 22.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
