Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

They cannot be changed according to foundation pits of different heights, which will cause waste of materials. In addition, disassembly and installation are also very troublesome, increasing the labor intensity of the staff.

[0024] In view of this, the utility model provides a combined foundation pit reinforcement device, which cooperates with support rods, threaded rods, threaded connecting tubes, square plates, hydraulic rods and support blocks. The threaded rods fixed on two support rods are connected by a threaded connecting tube to achieve the purpose of combining support rods.

[0025] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle.

The top of the reinforcement plate 2 is fixedly connected with a connecting plate 3, and the bottom of the reinforcement plate 2 is provided with a groove 4. A combined support mechanism is arranged above the base 1, and the combined support mechanism includes a support rod 5, a threaded rod 24, a threaded connection tube 6, a square plate 7, a hydraulic rod 8 and a support block 9. The support rod is arranged above the base, and the top and bottom of the support rod 5 are fixedly connected with a threaded rod 24, and the outer wall of the threaded rod 24 is threadedly connected with a threaded connection tube 6, and the outer wall of the threaded rod 24 is threaded. The thread pattern matches the inner wall thread of the threaded connection tube 6, and the purpose of such design is that the two support rods 5 can be screwed in and out by rotating the threaded rod 24 and the threaded connection tube 6 to achieve the purpose of installing or removing the support rod 5. The outer wall of the threaded connection tube 6 is fixedly connected with a square plate 7, and both sides of the square plate 7 are fixedly connected with hydraulic rods 8. The model of the hydraulic rod 8 is not limited. A support block 9 is installed at the end of the hydraulic rod 8. Such design is that the threaded connection tube 6 between the two support rods 5 is fixedly connected with the square plate 7. Under the cooperation of the hydraulic rod 8 and the support block 9 on the square plate 7, it plays a role in supporting both sides of the foundation pit, and the side of the support block 9 is in contact with the reinforcement plate 2;

[0027] In the specific implementation process, it is worth pointing out that the threaded rods 24 on the two support rods 5 are threadedly connected through the threaded connection tube 6, so that the support rods 5 can be combined according to the height in the foundation pit, and the height of the device is increased. At the same time, the number of threaded connection tubes 6, square plates 7, hydraulic rods 8 and support blocks 9 is increased, and the height of the device is changed to suit the height in the foundation pit. At the same time, the two reinforcement plates 2 on the same side are arranged in sequence from bottom to top, and the connecting plate 3 of one reinforcement plate 2 can be inserted into the groove 4 of the other reinforcement plate 2. The staff can select the number of reinforcement plates 2 according to the height in the foundation pit, and it is convenient to install and disassemble, and can be recycled many times;

[0028] Furthermore, a support column 10 is fixedly connected to the top of the base 1. The support column 10 can be made of a metal material such as aluminum alloy. A screw 17 is fixedly connected to the top of the support column 10. The screw 17 is threadedly connected to the bottom of the inner wall of the threaded connection tube 6.

[0029] In the specific implementation process, it is worth pointing out that the screw rod 17 on the support column 10 is connected to the threaded rod 24 on the support rod 5 through the threaded connection tube 6, so that the support column 10 can stably support a plurality of support rods 5, thereby improving the overall stability of the device;

[0030] Furthermore, the upper and lower parts of the reinforcing plate 2 near the base 1 are fixedly connected to the limiting tube 16, the inside of the limiting tube 16 is plugged with a movable block 18, the top of the movable block 18 is fixedly connected with an extrusion block 21, the movable block 18 passes through the inner wall of the limiting tube 16, the bottom of the movable block 18 is provided with a plug hole 19, the inside of the plug hole 19 is clamped with an insertion rod 25, the upper part of the outer wall of the movable block 18 is sleeved with a spring 20, and the top and bottom of the spring 20 are respectively fitted with the extrusion block 21 and the limiting tube 16;

[0031] During the specific implementation process, it is worth pointing out that when the staff needs to combine the reinforcement plates 2, the limiting tubes 16 on the upper and lower reinforcement blocks 2 are aligned and the extrusion block 21 is squeezed downward, and the spring 20 is also compressed. At the same time, the movable block 18 passes through the inner walls of the two limiting tubes 16. Then, the staff puts the insertion rod 25 into the insertion hole 19 at the lower end of the movable block 18 and releases the extrusion block 21. Due to the elastic deformation of the spring 20 and the limiting position of the insertion rod 25 in the insertion hole 19, the two reinforcement plates 2 can be further combined more closely, which is convenient for comprehensive reinforcement of the foundation pit over a large area, and avoids the impact on the reinforcement plate 2 in the event of foundation pit collapse.

[0032] Furthermore, an adjustment handle 22 is fixedly connected to the outer wall of the threaded connection tube 6, and an anti-skid pad 23 is provided on the outer wall of the support rod 5. The anti-skid pad 23 can be made of rubber material to facilitate the staff to take the support rod 5;

[0033] In the specific implementation process, it is worth pointing out that the function of the adjustment handle 22 is that the staff can rotate the adjustment handle 22 to tighten the threaded connecting tube 6 and the threaded rod 24 on the support rod 5 to prevent the problem of falling off;

[0034] Specifically, when using the combined foundation pit reinforcement device, the staff selects several support rods 5 according to the depth of the foundation pit, and then screws the threaded rod 24 on a support rod 5 into the screw 17 on the support column, and then combines the several support rods 5 from bottom to top through the threaded connection tube 6, and then inserts the connecting plate 3 fixedly connected to the top of one reinforcement plate 2 into the groove 4 provided at the bottom of another reinforcement plate 2 from bottom to top, and assembles and connects them, and then squeezes the extrusion block 21 to put the insertion rod 25 into the socket 19 in the movable block 18 to achieve the effect of further combining the reinforcement plates 2, so that the device can be suitable for foundation pits of different sizes.

[0035] Embodiment 2: By Figure 1 , 2 As shown in Figures 5 and 5, the two sides of the support column 10 are fixedly connected with a mounting plate 11, the inner side of the mounting plate 11 is rotatably connected with a telescopic rod 12 through a pin, and the end of the telescopic rod 12 is rotatably connected with a positioning block 13;

[0036] In the specific implementation process, it is worth pointing out that, because the mounting plate 11 and the telescopic rod 12 are in a rotational connection relationship, the staff can pull out the telescopic rod 12 and rotate it to a suitable angle so that the positioning block 13 at the end of the telescopic rod 12 contacts the ground. At the same time, because the end of the telescopic rod 12 and the positioning block 13 are also in a rotational relationship, the bottom of the positioning block 13 can be parallel to the ground.

[0037] Furthermore, a reserved hole 14 is provided on the inner wall of the positioning block 13, and a ground nail 15 is inserted into the reserved hole 14;

[0038] In the specific implementation process, it is worth pointing out that the ground nails 15 are inserted into the ground to increase the pressure between the support column 10 and the ground, thereby improving the overall stability of the device. At the same time, such a design can increase the support area of ​​the support column 10, disperse the load, and improve the bearing capacity of the support column 10;

[0039] Specifically, on the basis of the above-mentioned embodiment 1, the staff rotates the telescopic rod 12 rotatably connected to the mounting plate 11 so that the telescopic rod 12 is tilted at a reasonable position outside the support column 10, and then manually adjusts the length of the telescopic rod 12 so that the positioning block 13 rotatably connected to the end of the telescopic rod 12 is parallel to the ground, and then fixes the positioning block 13 to the ground through the reserved hole 14 with the ground nail 15, so that the support column 10 is stably fixed to the ground.
