Description

Technical Field

[0001] This utility model belongs to the field of ditch support, and in particular relates to a ditch support device for water conservancy and hydropower engineering construction. Background Technology

[0002] Water conservancy and hydropower engineering construction refers to the process of constructing water conservancy and hydropower facilities for purposes such as flood control, irrigation, power generation, water supply, and navigation in or around rivers, lakes, reservoirs, and other water bodies through a series of engineering and technical means. Its core is to achieve the rational utilization of water resources and disaster prevention by artificially intervening in and modifying the natural water environment.

[0003] In the construction of water conservancy and hydropower projects, the layout of underground water conveyance systems is a crucial link in the efficient allocation of water resources. This system typically requires the installation of water pipelines through surface trench excavation; however, construction conditions vary significantly depending on the geological environment. When encountering soft soil foundations or soil with high water content, the stability of the trench sidewalls is significantly reduced, easily leading to sidewall collapse or slippage. Such geological conditions can easily cause deformation and damage to the excavated trenches, increasing the difficulty of pipeline installation and seriously affecting construction progress and project quality. Utility Model Content

[0004] The purpose of this utility model is to provide a ditch support device for water conservancy and hydropower engineering construction, which prevents the collapse or slippage of both sides of the ditch without affecting the installation of water pipes, so as to ensure the construction progress and project quality.

[0005] The aforementioned ditch support device for water conservancy and hydropower engineering construction includes two vertically arranged baffles, which are aligned horizontally. A base plate is horizontally fixed to the bottom of the two baffles. Vertical rods are vertically fixed to the inner sidewalls of all the baffles. A sliding groove with vertical connection is opened on the inner sidewall of the vertical rod. A support rod is horizontally arranged between the two vertical rods. The two ends of the support rod are independently engaged in the two sliding grooves. A positioning component for detachable positioning of the support rod is provided on all the vertical rods. A vertically connected opening is opened on the base plate corresponding to the sliding groove.

[0006] Furthermore, an installation groove is provided on the groove wall at the end of the support rod corresponding to the slide groove. The installation groove is located in the lower half of the slide groove. Several rollers are rotatably installed in the installation groove. All rollers are evenly distributed in the vertical direction. The groove wall at the end of the support rod corresponding to the slide groove is flush with the outer surface of all rollers.

[0007] Furthermore, the positioning component includes a positioning pin, a through hole communicating with the slide groove is provided on the side wall of the vertical rod, and a positioning hole is provided on the support rod corresponding to the through hole, with the positioning pin independently inserted into the through hole and the positioning hole.

[0008] Furthermore, the base plate has several through holes, and each through hole is independently fitted with a ground nail.

[0009] Furthermore, a pull ring is fixed to the top of the ground nail.

[0010] Furthermore, the upper end of the ground stake is fitted with a retaining ring that fits against the top of the base plate.

[0011] Furthermore, a positioning groove is provided at the top center of the support rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: After the ditch is excavated, two baffles are first attached to the side walls of the ditch, ensuring the base plate is fully in contact with the ditch bottom, thus reinforcing the ditch side walls. Support rods are used to support the two baffles, preventing inward displacement. Before laying the water pipe, the pipe is placed in the positioning groove of the support rod, using the groove's limiting effect to position the pipe. During subsequent laying, the support rod is pressed downwards to move it towards the bottom of the ditch, ensuring it is in contact with the bottom. Before backfilling, the baffles and base plate are pulled upwards and removed, leaving the support rod embedded in the ditch for installation along with the water pipe. The support rod, positioned between the water pipe and the ditch bottom, effectively prevents the pipe from sinking and reduces damage caused by friction between the pipe and the ditch bottom. By sequentially installing several of these ditch support devices along the ditch, the side walls of the ditch are effectively reinforced, preventing collapse or slippage without affecting the water pipe installation, thus ensuring construction progress and project quality.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0015] Example This embodiment describes a ditch support device for water conservancy and hydropower engineering construction, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes two vertically arranged baffles 1, which are aligned horizontally and horizontally. The two baffles 1 are arranged opposite each other. When excavating a ditch, the two baffles 1 are attached to the two side walls of the ditch respectively. The baffles 1 are used to block and reinforce the two side walls of the ditch, thereby preventing the side walls of the ditch from collapsing or sliding. The bottom of the two baffles 1 is horizontally fixed with a base plate 7, such as Figure 1 and Figure 4 As shown, the sidewalls of the two baffles 1 facing each other are the inner sidewalls, and the sidewalls facing away from each other are the outer sidewalls; the baffles 1 and the base plate 7 are perpendicular to each other, and the outer end of the base plate 7 is flush with the outer sidewall of the baffles 1, so that the baffles 1 and the base plate 7 are combined to form an "L" shape; the base plate 7 can effectively increase the contact area with the bottom of the ditch, and the base plate 7 supports the baffles 1, so that the baffles 1 can be effectively kept vertical, and more effectively block the sidewalls of the ditch; The base plate 7 has several through holes, and each through hole is independently fitted with a ground nail 9; for example Figure 2 and Figure 4 As shown, two ground stakes 9 are spaced apart on the base plate 7. By inserting the ground stakes 9 into the soil at the bottom of the trench, the base plate 7 can be effectively fixed, preventing displacement during use and further enhancing the blocking effect of the baffle 1. The upper end of the ground stakes 9 is fitted with a retaining ring that fits against the top of the base plate 7, such as... Figure 2 and Figure 4 As shown, after the ground stake 9 is inserted into the ground, the retaining ring base plate 7 can block the base plate 7, preventing the base plate 7 from shifting during use, thus making the base plate 7 more stable; as Figure 3 and Figure 4 As shown, a pull ring is fixed to the top of the ground nail 9. The pull ring makes it easier for workers to pull upwards when pulling out the ground nail 9, making the process of pulling out the ground nail 9 easier and more convenient. Vertical rods 2 are fixed vertically on the inner sidewalls of all baffles 1, such as Figure 1 , Figure 2 and Figure 4 As shown, the vertical rod 2 is located in the middle of the inner wall of the baffle 1, and the vertical rods 2 on the left and right baffles 1 are parallel and aligned with each other; the vertical rod 2 can significantly improve the bending stiffness of the baffle 1, and by forming a combined structure, part of the load is transferred to the vertical rod 2, reducing the bending moment borne by the baffle 1 alone; A vertical groove 3 is provided on the inner side wall of the vertical rod 2, and a support rod 4 is horizontally arranged between the two vertical rods 2. The two ends of the support rod 4 are independently engaged in the two grooves 3; Figure 1 , Figure 2 and Figure 4As shown, the sliding grooves 3 on the two vertical rods 2 are parallel and aligned with each other. The two end faces of the support rod 4 are respectively attached to the corresponding groove walls of the two sliding grooves 3. The support rod 4 supports the baffles 1 on the left and right sides to prevent the two baffles 1 from moving inward. Figure 1 and Figure 4 As shown, the slide groove 3 and the support rod 4 are not fixed, so there is a gap between the support rod 4 and the groove wall of the slide groove 3, which allows the end of the support rod 4 to slide up and down along the corresponding slide groove 3. A positioning groove 5 is provided at the top center of the support rod 4; in this embodiment, the support rod 4 can be made of wood, concrete, concrete-reinforced concrete composite material, or wood chip-resin composite material, and the appropriate material is selected according to factors such as the service life of the buried water pipe, the cost of use, geological conditions, and the environment; for example Figure 1 , Figure 2 and Figure 4 As shown, before burying the water pipe, the water pipe can be placed on the support rod 4 so that the water pipe is engaged in the positioning groove 5. The positioning groove 5 is used to position the water pipe so that the water pipe can be aligned with the center of the ditch. This avoids the water pipe from being misaligned before, during and after burying, ensuring the installation accuracy of the water pipe, making the connection between the water pipes more accurate and tight, and avoiding problems such as water leakage. To elaborate further, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a preferred embodiment includes a positioning pin 10. A through hole communicating with the slide groove 3 is provided on the side wall of the vertical rod 2, and a positioning hole is provided on the support rod 4 corresponding to the through hole. The positioning pin 10 is independently installed in both the through hole and the positioning hole. Figure 1 , Figure 3 and Figure 4 As shown, when the baffle 1 reinforces the sides of the ditch, both ends of the support rod 4 are respectively engaged in the upper half of the slide 3, aligning the positioning hole on the support rod 4 with the through hole. The positioning pin 10 is independently inserted into the through hole and the positioning hole, thereby positioning the support rod 4 and ensuring that the support rod 4 continuously supports the two baffles 1. When it is necessary to move the support rod 4 downwards, simply pull out the positioning pin 10. This scheme constitutes a positioning assembly for detachable positioning of the support rod 4. Of course, the positioning assembly can also use bolts, on the side wall of the slide 3. A through hole is provided for the bolt to pass through. Corresponding to the through hole, a threaded hole is provided on the support rod 4 to engage with the bolt. When the baffle 1 blocks and reinforces both sides of the ditch, the two ends of the support rod 4 are respectively engaged in the upper half of the slide groove 3, so that the through hole on the support rod 4 is aligned with the threaded hole. The threaded end of the bolt is passed through the through hole, so that the bolt is fitted into the threaded hole, thereby fixing and positioning the support rod 4 and keeping the support rod 4 continuously supporting the two baffles 1. When it is necessary to move the support rod 4 downward in the future, simply loosen the bolt and pull it out.

[0016] The corresponding slide groove 3 has an opening 8 on the base plate 7 that connects vertically; for example Figure 1 , Figure 3 and Figure 4 As shown, when the support rod 4 moves towards the bottom of the ditch, its end can pass through the opening 8 of the two base plates 7, allowing the support rod 4 to fit snugly against the bottom of the ditch. During subsequent backfilling, the baffle 1 and base plate 7 are pulled up and removed, leaving the support rod 4 in the ditch and buried together with the water pipe. The support rod 4, positioned between the water pipe and the bottom of the ditch, prevents the water pipe from sinking. The bottom of the ditch may be uneven; if the water pipe is placed directly at the bottom, it may sink due to its own weight and the pressure of the soil above during subsequent backfilling and compaction. The support rod 4, placed between the water pipe and the bottom of the ditch, prevents the water pipe from sinking. Between the water pipe and the bottom of the ditch, a stable support surface is provided for the water pipe, which can evenly distribute the pressure on the water pipe, effectively prevent the water pipe from sinking, and ensure that the drainage pipe maintains a relatively stable position throughout its service life, ensuring the normal operation of the drainage system; reduce friction between the water pipe and the bottom of the ditch: during the installation and subsequent use of the water pipe, the water pipe may be worn due to friction with the bottom of the ditch. The support rod 4, as a buffer layer between the water pipe and the bottom of the ditch, can reduce the direct contact and friction between the water pipe and the bottom of the ditch, reduce the degree of wear on the water pipe, and extend the service life of the water pipe; A mounting groove is provided on the groove wall at the end of the sliding groove 3 corresponding to the support rod 4. The mounting groove is located in the lower half of the sliding groove 3, and several rollers 6 are rotatably mounted in the mounting groove. All rollers 6 are evenly distributed in the vertical direction, and the groove wall at the end of the sliding groove 3 corresponding to the support rod 4 is flush with the outer surface of all rollers 6. Figure 1 , Figure 3 and Figure 4 As shown, when the support rod 4 moves downward, the end face of the groove 3 will contact the roller 6, and the rolling friction will replace the sliding friction, thereby significantly reducing the resistance when the support rod 4 moves, making it easier for the support rod 4 to move downward.

[0017] In actual use, after the ditch is dug, the two baffles 1 are first attached to the two side walls of the ditch, while ensuring that the bottom plate 7 is completely attached to the bottom of the ditch. The bottom plate 7 effectively increases the contact area with the bottom of the ditch, and its supporting effect keeps the baffles 1 in a vertical state, so as to reinforce the blocking of the ditch side walls. Subsequently, ground nails 9 are inserted into the pre-set through holes in the base plate 7, and the ground nails 9 are vertically inserted into the soil layer at the bottom of the trench to form a stable anchoring structure, effectively preventing the base plate 7 from shifting during use. Next, the two ends of the support rod 4 are respectively inserted into the upper half of the sliding groove 3 on the two vertical rods 2, so that the end face of the support rod 4 fits against the groove wall of the sliding groove 3, forming a transverse support system to prevent the two baffles 1 from shifting inward; After the support rod 4 is in place, adjust its position so that the positioning holes at both ends are aligned with the corresponding through holes of the vertical rod 2. Then, insert the positioning pin 10 independently into the through holes and positioning holes to complete the positioning and fixing of both ends of the support rod 4 and ensure its continuous and stable support. Before burying the water pipe, the water pipe can be placed in the positioning groove 5 of the support rod 4. The positioning groove 5 will limit the positioning of the water pipe. During subsequent installation, all positioning pins 10 must be pulled out first, and then the support rod 4 should be pressed down to move it towards the bottom of the ditch. The two ends of the support rod 4 will move down smoothly through the pre-set openings 8 of the base plate 7 until they are completely in contact with the bottom of the ditch. Before backfilling, the baffle 1 and the base plate 7 should be pulled up and removed, leaving the support rod 4 buried in the ditch along with the water pipe. The support rod 4, located between the water pipe and the bottom of the ditch, can effectively prevent the water pipe from sinking and reduce the damage caused by friction between the water pipe and the bottom of the ditch. By sequentially installing several ditch support devices along the ditch, the two side walls of the ditch can be effectively supported and reinforced. Without affecting the installation of water pipes, the collapse or slippage of the two sides of the ditch can be prevented, ensuring the construction progress and project quality.
