Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline construction, specifically to a pipeline positioning device. Background Technology
[0002] Pipeline engineering is an important form of modern engineering structure. Depending on the construction method, pipelines can be constructed using open excavation, pipe jacking, or tunnel boring machines (TBMs). Different construction methods are suitable for different technological processes and operating conditions. The open excavation method is suitable for plains areas. According to construction requirements, a corresponding construction cross-section is excavated, generally including a slope and a bottom surface. Then, the pipeline is hoisted into the bottom surface and fixed, and the soil is backfilled.
[0003] For water pipelines, which are generally large in size, necessary positioning is required during hoisting to prevent large displacement. Existing positioning methods rely heavily on manual experience, which results in large positioning deviations and cannot achieve effective displacement calibration. Summary of the Invention
[0004] This utility model addresses the problems of the prior art by providing a pipeline positioning device. Through reasonable design of the positioning device, it achieves reasonable and efficient positioning during pipeline construction.
[0005] This utility model provides a pipe positioning device. The pipe is a water pipeline. A slope and a bottom horizontal surface are formed by excavating the ground. A coarse sand cushion layer is placed on the bottom horizontal surface, and a concrete cushion layer is placed on top of the coarse sand cushion layer. Both the coarse sand cushion layer and the concrete cushion layer are connected to the slope. The device comprises a left positioning plate, a right positioning plate, a pad plate, a left fixing plate, a right fixing plate, a left spring, and a right spring. The left and right positioning plates are symmetrically arranged along the central axis of the pipe. Both the left and right positioning plates are fixedly connected to the pad plate. The upper surface of the pad plate has an arc-shaped surface, which is aligned with the pipe... The dimensions are compatible. Both the left and right positioning plates include a vertical plate and a folded plate, which are fixedly connected and integrally formed. The left and right fixing plates are symmetrically arranged along the central axis of the pipeline, and both are fixed to the concrete pad by anchor rods. The anchor rods pass through the coarse sand pad and the concrete pad, penetrating deep into the foundation. The folded plate of the left positioning plate is fixedly connected to the left fixing plate by a left spring, and the folded plate of the right positioning plate is fixedly connected to the right fixing plate by a right spring. The pipeline is located between the left and right positioning plates and on the pad.
[0006] Preferably, the left positioning plate and the right positioning plate are integrally formed with the pad, and the left positioning plate, the right positioning plate and the pad are all fixed on the concrete pad.
[0007] Preferably, the concrete pad is provided with pre-embedded bolts during the pouring process. The pre-embedded bolts extend out of the pad plate, and the pad plate is provided with through holes that mate with the pre-embedded bolts. By setting nuts on the pre-embedded bolts, the pad plate and the concrete pad are fixedly connected, thereby achieving the fixed connection between the left fixing plate, the right fixing plate, the pad plate and the concrete pad.
[0008] Preferably, the left positioning plate, the right positioning plate, and the pad are all made of rubber.
[0009] Preferably, the left fixing plate and the right fixing plate are made of steel, and the anchor rod is connected to the left fixing plate and the right fixing plate by welding or bolting.
[0010] The working principle of this utility model is as follows:
[0011] For pipeline construction, positioning devices need to be fabricated according to the shape of the pipeline. The left and right positioning plates in the positioning device are made of rubber, and their flexible structure will not damage the outer wall of the pipeline. Both the left and right positioning plates include folded plates at a certain angle, creating upward openings that facilitate pipeline hoisting and placement. The positioning device includes a pad, which acts as a damping buffer, preventing direct contact and friction between the pipeline and the concrete base layer, thus avoiding rigidity damage. The upper surface of the pad has an arc-shaped surface that matches the dimensions of the pipeline. This arc-shaped surface not only serves a positioning function but also utilizes the pipeline's weight to enhance contact between the pipeline and the pad, reducing friction. The left and right fixing plates are integrally formed with the pad and fixed to the concrete base layer. When bolts are used for fixing, the bolt positions should avoid the arc-shaped surface.
[0012] A left and right fixing plate are installed on a concrete pad. The left positioning plate is fixedly connected to the left fixing plate via a left spring, and the right positioning plate is fixedly connected to the right fixing plate via a right spring. During pipe hoisting and placement, displacement may cause stress on the folding plate. The spring and fixing plate ensure the stability of the folding plate. Especially when the stress increases, the spring provides damping and energy dissipation. The greater the displacement, the greater the spring force, preventing excessive stress and displacement on the folding plate during pipe hoisting, which could cause damage. Simultaneously, the spring and folding plate work together to apply a force to the pipe, helping it move along the opening formed by the folding plate, thus ensuring the pipe's positioning and hoisting. By setting the corresponding left and right positioning plates, the pipe positioning operation is achieved. The folding plate forms an upward opening, facilitating initial pipe positioning at the opening. If displacement deviation occurs, the folding plate and spring generate a reaction force, ensuring the pipe moves along the vertical direction of the positioning plate and ultimately engages with the curved surface of the pad to complete the positioning work.
[0013] The advantages of this utility model are:
[0014] This utility model provides a pipe positioning device for positioning pipes after slope excavation. The device creates a slope and a bottom horizontal surface through ground excavation. A coarse sand layer and a concrete layer are placed on the bottom horizontal surface. A left positioning plate, a right positioning plate, and a pad are fixed on the concrete layer. The upper surface of the pad has an arc-shaped surface adapted to the pipe size. Both the left and right positioning plates include a vertical plate and a folded plate. A left and right fixing plate are placed on the concrete layer, and the folded plate is fixedly connected to the left and right fixing plates by left and right springs, respectively. This pipe positioning device enables accurate positioning of pipes during hoisting, preventing significant pipe displacement. Attached Figure Description

[0018] The following provides a detailed explanation of the limitations of this utility model.
[0019] This utility model provides a pipe positioning device, wherein the pipe 1 is a water conveyance pipe 1, and a slope 2 and a bottom horizontal surface are formed by excavating the ground. A coarse sand cushion layer 3 is set on the bottom horizontal surface, and a concrete cushion layer 4 is set on the coarse sand cushion layer 3. Both the coarse sand cushion layer 3 and the concrete cushion layer 4 are connected to the slope 2. The device is characterized in that: the pipe 1 positioning device includes a left positioning plate 5, a right positioning plate 6, a pad 7, a left fixing plate 8, a right fixing plate 9, a left spring 10, and a right spring 11. The left positioning plate 5 and the right positioning plate 6 are symmetrically arranged along the central axis of the pipe 1. Both the left positioning plate 5 and the right positioning plate 6 are fixedly connected to the pad 7. The upper surface of the pad 7 is provided with an arc-shaped surface, and the arc-shaped surface is symmetrical with respect to the dimensions of the pipe 1. The left positioning plate 5 and the right positioning plate 6 are adapted to each other. Both include a vertical plate 51 and a folded plate 52. The vertical plate 51 and the folded plate 52 are fixedly connected and integrally formed. The left fixing plate 8 and the right fixing plate 9 are symmetrically arranged along the central axis of the pipe 1. Both the left fixing plate 8 and the right fixing plate 9 are fixed to the concrete pad 4 by anchor rods. The anchor rods pass through the coarse sand pad 3 and the concrete pad 4 and penetrate into the foundation. The folded plate 52 of the left positioning plate 5 is fixedly connected to the left fixing plate 8 by a left spring 10. The folded plate 52 of the right positioning plate 6 is fixedly connected to the right fixing plate 9 by a right spring 11. The pipe 1 is located between the left positioning plate 5 and the right positioning plate 6 and is located on the pad 7.
[0020] A cavity is formed between the left positioning plate 5 and the right positioning plate 6 to accommodate the pipe 1, which is used to position and place the pipe 1. The folding plate 52 forms an upward opening. When the pipe 1 is hoisted and placed, the opening position is first positioned, and then it is placed on the arc-shaped surface of the pad 7 between the left positioning plate 5 and the right positioning plate 6. The left positioning plate 5, the right positioning plate 6, the left fixing plate 8, and the right fixing plate 9 are all symmetrically arranged along the center line of the pipe 1.
[0021] Preferably, the left positioning plate 5 and the right positioning plate 6 are integrally formed with the pad 7, and the left positioning plate 5, the right positioning plate 6 and the pad 7 are all fixed on the concrete pad 4.
[0022] Preferably, the concrete pad 4 is pre-embedded with bolts during pouring, with the bolts extending out of the pad 7. The pad 7 has through holes that mate with the pre-embedded bolts. By placing nuts on the pre-embedded bolts, the pad 7 is fixedly connected to the concrete pad 4, thereby achieving a fixed connection between the left fixing plate 8, the right fixing plate 9, the pad 7, and the concrete pad 4. The openings on the pad 7 should be staggered from the arc-shaped surface to ensure that there are no nuts on the arc-shaped surface. Preferably, the openings are located on both sides of the pad 7.
[0023] Preferably, the left positioning plate 5, the right positioning plate 6, and the pad 7 are all made of rubber. However, the materials of the left positioning plate 5, the right positioning plate 6, and the pad 7 can also be other materials with flexible properties.
[0024] Preferably, the left fixing plate 8 and the right fixing plate 9 are made of steel, and the anchor rod is connected to the left fixing plate 8 and the right fixing plate 9 by welding or bolting.
[0025] The positioning devices are set at intervals along the excavation section, or they can be set along the entire length. To save costs, it is generally sufficient to set one at each end of the pipeline 1. After the section is excavated and the coarse sand cushion layer 3 and concrete cushion layer 4 are formed, the corresponding positioning devices are set. After the pipeline 1 is hoisted and positioned, the positioning devices are not removed, and the soil can be backfilled directly.
