Description

Technical Field

[0001] This utility model relates to the field of urban drainage construction equipment technology, specifically to a pipeline support structure for urban drainage construction. Background Technology

[0002] Urban drainage pipe networks are one of the most important infrastructures in a city. During the construction of pipeline projects, it is necessary to first dig pipe trenches. The walls of the foundation pits are easily affected by groundwater and precipitation and may collapse. Therefore, it is necessary to support the trenches and pipes.

[0003] Currently, when supporting drainage pipelines, retaining walls are typically installed on both sides of the trench, and support rods are used to brace the retaining walls to prevent trench collapse. There are various types of support rods available; adjustable-length support rods usually involve threaded structures, with the length adjusted by rotating the corresponding threaded sleeve. However, the threads of this type of support pipe are usually exposed, making them prone to accumulating rainwater and dust, which can damage the threads. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pipeline support structure for urban drainage construction, addressing the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A pipe support structure for urban drainage construction includes retaining plates, support rods and pads. Multiple retaining plates are provided on both sides of the trench, and multiple pads are provided at the bottom of the trench. The support rod includes a first connecting rod, a second connecting rod, and a sleeve. The first ends of the first connecting rod and the second connecting rod can be detachably connected to the retaining plate. The second ends of the first connecting rod and the second connecting rod are provided with threaded holes. A fixing part is provided inside the sleeve. Both ends of the fixing part are provided with screws. The screws can be assembled with the threaded holes. Both ends of the inner side of the sleeve are provided with sealing rings.

[0006] Furthermore, the first ends of both the first connecting rod and the second connecting rod are hinged with mounting seats, which can be detachably connected to the retaining plate.

[0007] Furthermore, the retaining plate has an installation part on the side away from the trench. The installation part includes two vertically arranged side plates, which are parallel to each other and perpendicular to the retaining plate. The mounting base and the side plates can be fixedly connected by bolts.

[0008] Furthermore, the mounting part also includes a U-shaped plate, which is disposed between the two side plates, and the mounting base and the U-shaped plate can be fixedly connected by bolts.

[0009] Furthermore, there are two mounting parts, which are located on both sides of the retaining plate.

[0010] Furthermore, the top of the retaining plate is provided with several slots, and the bottom of the retaining plate is provided with several inserts, the inserts being able to be inserted into the slots.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The first and second connecting rods of the support rod in this application are connected by a sleeve and assembled by a threaded connection. When the sleeve rotates, the relative position of the first and second connecting rods can be adjusted to change the length of the support rod, so that the support rod abuts against the retaining plates on both sides to support the pipeline trench. The sleeve is provided with sealing rings at both ends. When the sleeve is connected to the connecting rod, the sealing rings can fill the gap between the sleeve and the connecting rod to prevent rainwater and dust from entering, prevent the threads from being damaged, and improve the service life of the support rod.

[0017] Example 1 like Figure 1 As shown in the figure, this embodiment discloses a pipeline support structure for urban drainage construction, including a retaining plate 1, a support rod 2, and a pad 3.

[0018] A pad 3 is provided at the bottom of the trench 4, and multiple pads 3 are provided along the length of the trench 4, and the pipe 5 can be placed on the pad 3.

[0019] Retaining plates 1 are installed on both sides of the trench 4, and multiple retaining plates 1 are installed along the length of the trench 4, with support rods 2 installed between the retaining plates 1.

[0020] Figure 2 and Figure 4 As shown, the support rod 2 includes a first connecting rod 21, a second connecting rod 22, and a sleeve 23. The first end of the first connecting rod 21 can be detachably connected to one of the retaining plates 1. The other end of the first connecting rod 21 has a threaded hole 24. The first end of the second connecting rod 22 can be detachably connected to the other retaining plate 1. The second end of the second connecting rod 12 has a threaded hole 24. A fixing part 231 is provided in the middle of the inner side of the sleeve 23. Both ends of the fixing part 231 are provided with screws 232. The screws 232 can be threaded into the threaded hole 24. Both ends of the inner side of the sleeve 23 are provided with sealing rings 25. When the first connecting rod 21 / second connecting rod 12 is connected to the sleeve 23, the sealing rings 25 can fill the gap between the sleeve 23 and the first connecting rod 21 / second connecting rod 12, thereby preventing rainwater and dust from entering the sleeve.

[0021] Both ends of the inner side of the sleeve 23 are provided with annular grooves, and the sealing ring 25 is embedded in the annular grooves.

[0022] like Figure 3As shown, the retaining plate 1 is provided with two mounting parts 11. The mounting parts 11 are located on the side of the retaining plate 1 away from the trench 4, and the two mounting parts 11 are respectively located on both sides of the retaining plate 1. The mounting part 11 includes two side plates 111 and two U-shaped plates 112. The two side plates 111 are both vertically arranged and parallel to each other, and the side plates 111 are perpendicular to the retaining plate 1. The U-shaped plates 112 are arranged between the two side plates 111, and the two U-shaped plates 112 are distributed on the upper and lower parts of the side plates 111. The U-shaped plates 112 are used to connect the two side plates and also serve a reinforcement function.

[0023] Specifically, in this embodiment, the two side plates 111 are formed by bending sheet metal. The plate connecting the two side plates 111 can be fixed to the retaining plate 1 by welding or bolting.

[0024] Specifically, multiple assembly holes are provided on both the side plate 111 and the U-shaped plate 112. The first end of the first connecting rod 21 and the second connecting rod 22 is provided with a mounting seat 26. The mounting seat 26 is provided with a strip hole, so that the mounting seat 26 and the side plate 111 / U-shaped plate 112 can be fixedly connected by bolts.

[0025] Specifically, the outer side of the sleeve 23 has two opposing planes, allowing the sleeve 23 to be gripped and rotated using tools such as wrenches to adjust the length of the support rod 2. Additionally, a handle can be provided on the outer side of the sleeve 23 for easy manual rotation by the operator.

[0026] Workflow: After the trench 4 is dug, the pad block 3 is placed in the trench 4, and the pipe 5 is hoisted into the trench 4 by the lifting equipment, and the pad block 3 is used to support and limit the pipe 5. Multiple retaining plates 1 are inserted on both sides of the trench 4, and the support rods 2 (first connecting rod 21, second connecting rod 22 and sleeve 23 in the assembled state) are hoisted into the trench 4, and the two mounting seats 26 are respectively placed between the corresponding two side plates 111. By rotating the sleeve 23, the relative distance between the first connecting rod 21 and the second connecting rod 22 can be adjusted so that the support rod 2 extends to the preset length and abuts against the two retaining plates 1 to support the pit wall. Then the mounting seats 26 can be fixed to the two side plates 111 with bolts.

[0027] Understandably, the above installation process is only an example. During construction, the installation sequence and the installation position of the mounting base 26 can be adjusted according to actual needs. For example, the mounting base 26 can be installed between the two side plates 111 on two adjacent retaining walls 1. Figure 5 As shown.

[0028] Example 2 This embodiment is an improvement on embodiment 1.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the top of the retaining plate 1 is provided with multiple slots 12, and the bottom of the retaining plate 1 is provided with multiple inserts 13, which can be inserted into the corresponding slots 12. During construction, the insert 13 at the bottom of the lowest retaining plate 1 can be inserted into the bottom of the trench 4 so that the retaining plate 1 can be initially fixed in the trench 4.

[0030] When the trench 4 is deep, multiple retaining plates 1 can be stacked vertically to meet the construction depth requirements. When connecting the upper and lower retaining plates 1, align the insert 13 at the bottom of the upper retaining plate 1 with the slot 12 at the top of the lower retaining plate 1, and continue to lower the upper retaining plate 1 so that the two retaining plates 1 can be spliced ​​together.

[0031] Preferably, when two or more retaining plates 1 are stacked vertically, before installing the retaining plates 1, I-beams can be inserted at intervals on both sides of the trench 4 so that when installing the retaining plates 1, the retaining plates 1 are embedded between two adjacent I-beams to limit the position of the retaining plates 1.
