Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and more specifically to a drainage pipe support frame for water conservancy and hydropower engineering. Background Technology

[0002] In water conservancy and hydropower projects, when laying drainage pipes, it is necessary to excavate a foundation pit, lay the drainage pipes, and then backfill. Since the foundation pit has a certain depth, especially after the deep foundation pit is excavated, the side walls are prone to collapse, which poses a great risk to the workers on site. At present, drainage pipe support frames are generally used to support the side walls on both sides of the foundation pit, which plays a good role in preventing collapse. However, it also has certain drawbacks. Especially when the foundation pit is wide, the support rods of common support frames have a large self-weight, so the middle of the support rod is easy to bend downward, causing the direction of the support force to change and the support effect to drop significantly. Utility Model Content

[0003] One advantage of this utility model is that it provides a drainage pipe support frame for water conservancy and hydropower projects. The support rod has two functions: it can not only be set horizontally to achieve the effect of a conventional support rod, but also provide diagonal support to strengthen the structural strength and prevent the middle of the support rod from bending downward, thus effectively improving the stability of the support effect and ensuring the safety of the foundation pit.

[0004] To achieve at least one of the above advantages of this utility model, this utility model provides a drainage pipe support frame for water conservancy and hydropower projects, including two guard plate assemblies, and a support assembly is provided between the two guard plate assemblies.

[0024] The first embodiment of this utility model is as follows:

[0025] A drainage pipe support frame for water conservancy and hydropower projects includes two protective plate assemblies. The two protective plate assemblies are located on both sides of the foundation pit, closely attached to the side wall to support the vertical slope of the side wall. The protective plate assembly includes a protective plate 1, which is a flat plate structure with a smooth front. Two sets of connecting seats are symmetrically arranged on both sides of the back of the protective plate 1. Each set of connecting seats includes two vertically parallel ear plates 2. Several pin holes 8 are evenly arranged on the ear plates 2. According to the specific configuration during use, a set number of pins 11 can be inserted into the corresponding pin holes 8. The ends of the pins 11 are threaded and tightened with nuts.

[0026] Depending on the depth of the pit, multiple protective plates 1 can be connected vertically. The upper end of the protective plate 1 is provided with a notch 9 with an inclined lower surface, and the lower end of the protective plate 1 is provided with a protrusion 10 that matches the notch 9. Two adjacent protective plates 1 are connected as one unit through the coupling of the notch 9 and the protrusion 10, ensuring stable connection and easy disassembly, while the front can form a complete plane.

[0027] Several reinforcing plates 12 are horizontally arranged on the back of the protective plate 1. The two ends of the reinforcing plates 12 are fixedly connected to the ear plates 2 on both sides. A reinforcing plate 12 is also vertically arranged on the back of the protective plate 1 to connect all the horizontal reinforcing plates 12 and improve the strength of the structure.

[0028] A support assembly is also provided between the two guard plate assemblies. The two ends of the support assembly are detachably connected to the two guard plate assemblies, so that the two guard plate assemblies can be firmly pressed against the vertical earth slope of the side wall.

[0029] The support assembly includes a lateral support component and an oblique support component that keeps the lateral support component horizontal. The lateral support component includes two support rods 3. A connecting block 7 is fixedly installed at one end of each support rod 3. The other end of the connecting block 7 is provided with a groove with the same diameter as the pin 11. During installation, the connecting block 7 can be directly snapped onto the pin 11. At the same time, the end of the connecting block 7 is also provided with an inclined surface, which allows it to rotate on the pin 11. This setting is to ensure the versatility of the support rods 3. The support rods 3 of the oblique support component are the same as the support rods 3 of the lateral support component, which improves ease of use.

[0030] The other end of the support rod 3 is provided with a second insert 18.

[0031] The lateral support component also includes a telescopic rod 4, which is located between the two support rods 3 and is coupled to the second support rod 18 via a first insert 13. The telescopic rod 4 includes a sub-rod 6 and a mother rod 19. The sub-rod 6 has a first insert 13 adapted to the second insert 18 at one end facing the support rod 3, and the mother rod 19 has a first insert 13 adapted to the second insert 18 at the other end. Both the first insert 13 and the second insert 18 have adapted through holes. After the second insert 18 and the first insert 13 are coupled, they are connected by bolts 5, thereby connecting the sub-rod 6 and the mother rod 19 to the two support rods 3 respectively.

[0032] The other end of the sub-rod 6 is provided with a lead screw 14, and a nut 15 is engaged with the lead screw 14. The end of the female rod 19 facing the sub-rod 6 is provided with a blind hole 16. The inner diameter of the blind hole 16 is slightly larger than the outer diameter of the lead screw 14. The lead screw 14 is inserted into the blind hole 16. The outer surface of the nut 15 is hexagonal. The nut 15 can be turned with a wrench to move laterally on the lead screw 14. When the nut 15 moves toward the female rod 19 and hits the female rod 19, the overall length of the lateral support component can be increased by continuing to turn the nut 15, thereby pushing the two guard plate assemblies open to both sides.

[0033] To ensure that the middle part of the transverse support component does not bend downward, an oblique support component is provided. The oblique support component includes a support rod 3 that is common to the transverse support component. A third insert 17 is provided at the lower part of the support rod 3 near the second insert 18. The third insert 17 of the support rod 3 of the oblique support component is connected to the second insert 18 of the support rod 3 of the transverse support component by bolts 5.

[0034] During installation, select an appropriate number of protective plate components based on the depth of the pit, and then attach them to the side walls on both sides of the pit. At this time, the workers straighten them, and then install the mounting block of the support rod 3 onto the pin 11 at the preset position. Then, insert the lead screw 14 of the sub-rod 6 into the blind hole 16 of the mother rod 19. Then, install the sub-rod 6 and the mother rod 19 onto the two support rods 3 respectively through the first insert 13 and the second insert 18. Then, install the universal support rod 3 onto the preset pin 11, with a pin hole 8 between the two pins 11. Then, rotate the support rod 3 so that its second insert 18 is coupled with the third insert 17 of the upper transverse support rod 3. Then, use bolts 5 to connect and fix it to form a triangular structure. Finally, tighten the nut 15 to achieve the preset support force, and the overall safety is completed.

[0035] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
